+Part III - Debug drivers use of the DMA-API
+-------------------------------------------
+
+The DMA-API as described above as some constraints. DMA addresses must be
+released with the corresponding function with the same size for example. With
+the advent of hardware IOMMUs it becomes more and more important that drivers
+do not violate those constraints. In the worst case such a violation can
+result in data corruption up to destroyed filesystems.
+
+To debug drivers and find bugs in the usage of the DMA-API checking code can
+be compiled into the kernel which will tell the developer about those
+violations. If your architecture supports it you can select the "Enable
+debugging of DMA-API usage" option in your kernel configuration. Enabling this
+option has a performance impact. Do not enable it in production kernels.
+
+If you boot the resulting kernel will contain code which does some bookkeeping
+about what DMA memory was allocated for which device. If this code detects an
+error it prints a warning message with some details into your kernel log. An
+example warning message may look like this:
+

+The driver developer can find the driver and the device including a stacktrace
+of the DMA-API call which caused this warning.
+
+Per default only the first error will result in a warning message. All other
+errors will only silently counted. This limitation exist to prevent the code
+from flooding your kernel log. To support debugging a device driver this can
+be disabled via debugfs. See the debugfs interface documentation below for
+details.
+
+The debugfs directory for the DMA-API debugging code is called dma-api/. In
+this directory the following files can currently be found:
+
+	dma-api/all_errors	This file contains a numeric value. If this
+				value is not equal to zero the debugging code
+				will print a warning for every error it finds
+				into the kernel log. Be carefull with this
+				option. It can easily flood your logs.
+
+	dma-api/disabled	This read-only file contains the character 'Y'
+				if the debugging code is disabled. This can
+				happen when it runs out of memory or if it was
+				disabled at boot time
+
+	dma-api/error_count	This file is read-only and shows the total
+				numbers of errors found.
+
+	dma-api/num_errors	The number in this file shows how many
+				warnings will be printed to the kernel log
+				before it stops. This number is initialized to
+				one at system boot and be set by writing into
+				this file
+
+	dma-api/min_free_entries
+				This read-only file can be read to get the
+				minimum number of free dma_debug_entries the
+				allocator has ever seen. If this value goes
+				down to zero the code will disable itself
+				because it is not longer reliable.
+
+	dma-api/num_free_entries
+				The current number of free dma_debug_entries
+				in the allocator.
+
+If you have this code compiled into your kernel it will be enabled by default.
+If you want to boot without the bookkeeping anyway you can provide
+'dma_debug=off' as a boot parameter. This will disable DMA-API debugging.
+Notice that you can not enable it again at runtime. You have to reboot to do
+so.
+
+When the code disables itself at runtime this is most likely because it ran
+out of dma_debug_entries. These entries are preallocated at boot. The number
+of preallocated entries is defined per architecture. If it is too low for you
+boot with 'dma_debug_entries=<your_desired_number>' to overwrite the
+architectural default.

 1. About this guide
 
-This guide describes the basics of Message Signaled Interrupts (MSI),
-the advantages of using MSI over traditional interrupt mechanisms,
-and how to enable your driver to use MSI or MSI-X. Also included is
-a Frequently Asked Questions (FAQ) section.
-
-1.1 Terminology
-
-PCI devices can be single-function or multi-function.  In either case,
-when this text talks about enabling or disabling MSI on a "device
-function," it is referring to one specific PCI device and function and
-not to all functions on a PCI device (unless the PCI device has only
-one function).
-
-2. Copyright 2003 Intel Corporation
-
-3. What is MSI/MSI-X?
-
-Message Signaled Interrupt (MSI), as described in the PCI Local Bus
-Specification Revision 2.3 or later, is an optional feature, and a
-required feature for PCI Express devices. MSI enables a device function
-to request service by sending an Inbound Memory Write on its PCI bus to
-the FSB as a Message Signal Interrupt transaction. Because MSI is
-generated in the form of a Memory Write, all transaction conditions,
-such as a Retry, Master-Abort, Target-Abort or normal completion, are
-supported.
-
-A PCI device that supports MSI must also support pin IRQ assertion
-interrupt mechanism to provide backward compatibility for systems that
-do not support MSI. In systems which support MSI, the bus driver is
-responsible for initializing the message address and message data of
-the device function's MSI/MSI-X capability structure during device
-initial configuration.
-
-An MSI capable device function indicates MSI support by implementing
-the MSI/MSI-X capability structure in its PCI capability list. The
-device function may implement both the MSI capability structure and
-the MSI-X capability structure; however, the bus driver should not
-enable both.
-
-The MSI capability structure contains Message Control register,
-Message Address register and Message Data register. These registers
-provide the bus driver control over MSI. The Message Control register
-indicates the MSI capability supported by the device. The Message
-Address register specifies the target address and the Message Data
-register specifies the characteristics of the message. To request
-service, the device function writes the content of the Message Data
-register to the target address. The device and its software driver
-are prohibited from writing to these registers.
-
-The MSI-X capability structure is an optional extension to MSI. It
-uses an independent and separate capability structure. There are
-some key advantages to implementing the MSI-X capability structure
-over the MSI capability structure as described below.
-
-	- Support a larger maximum number of vectors per function.
-
-	- Provide the ability for system software to configure
-	each vector with an independent message address and message
-	data, specified by a table that resides in Memory Space.
-
-        - MSI and MSI-X both support per-vector masking. Per-vector
-	masking is an optional extension of MSI but a required
-	feature for MSI-X. Per-vector masking provides the kernel the
-	ability to mask/unmask a single MSI while running its
-	interrupt service routine. If per-vector masking is
-	not supported, then the device driver should provide the
-	hardware/software synchronization to ensure that the device
-	generates MSI when the driver wants it to do so.
-
-4. Why use MSI?
-
-As a benefit to the simplification of board design, MSI allows board
-designers to remove out-of-band interrupt routing. MSI is another
-step towards a legacy-free environment.
-
-Due to increasing pressure on chipset and processor packages to
-reduce pin count, the need for interrupt pins is expected to
-diminish over time. Devices, due to pin constraints, may implement
-messages to increase performance.
-
-PCI Express endpoints uses INTx emulation (in-band messages) instead
-of IRQ pin assertion. Using INTx emulation requires interrupt
-sharing among devices connected to the same node (PCI bridge) while
-MSI is unique (non-shared) and does not require BIOS configuration
-support. As a result, the PCI Express technology requires MSI
-support for better interrupt performance.
-
-Using MSI enables the device functions to support two or more
-vectors, which can be configured to target different CPUs to
-increase scalability.
-
-5. Configuring a driver to use MSI/MSI-X
-
-By default, the kernel will not enable MSI/MSI-X on all devices that
-support this capability. The CONFIG_PCI_MSI kernel option
-must be selected to enable MSI/MSI-X support.
-
-5.1 Including MSI/MSI-X support into the kernel
-
-To allow MSI/MSI-X capable device drivers to selectively enable
-MSI/MSI-X (using pci_enable_msi()/pci_enable_msix() as described
-below), the VECTOR based scheme needs to be enabled by setting
-CONFIG_PCI_MSI during kernel config.
-
-Since the target of the inbound message is the local APIC, providing
-CONFIG_X86_LOCAL_APIC must be enabled as well as CONFIG_PCI_MSI.
-
-5.2 Configuring for MSI support
-
-Due to the non-contiguous fashion in vector assignment of the
-existing Linux kernel, this version does not support multiple
-messages regardless of a device function is capable of supporting
-more than one vector. To enable MSI on a device function's MSI
-capability structure requires a device driver to call the function
-pci_enable_msi() explicitly.
-
-5.2.1 API pci_enable_msi
+This guide describes the basics of Message Signaled Interrupts (MSIs),
+the advantages of using MSI over traditional interrupt mechanisms, how
+to change your driver to use MSI or MSI-X and some basic diagnostics to
+try if a device doesn't support MSIs.
 
-int pci_enable_msi(struct pci_dev *dev)
 
-With this new API, a device driver that wants to have MSI
-enabled on its device function must call this API to enable MSI.
-A successful call will initialize the MSI capability structure
-with ONE vector, regardless of whether a device function is
-capable of supporting multiple messages. This vector replaces the
-pre-assigned dev->irq with a new MSI vector. To avoid a conflict
-of the new assigned vector with existing pre-assigned vector requires
-a device driver to call this API before calling request_irq().
+2. What are MSIs?
 
-5.2.2 API pci_disable_msi
+A Message Signaled Interrupt is a write from the device to a special
+address which causes an interrupt to be received by the CPU.
 
-void pci_disable_msi(struct pci_dev *dev)
+The MSI capability was first specified in PCI 2.2 and was later enhanced
+in PCI 3.0 to allow each interrupt to be masked individually.  The MSI-X
+capability was also introduced with PCI 3.0.  It supports more interrupts
+per device than MSI and allows interrupts to be independently configured.
 
-This API should always be used to undo the effect of pci_enable_msi()
-when a device driver is unloading. This API restores dev->irq with
-the pre-assigned IOAPIC vector and switches a device's interrupt
-mode to PCI pin-irq assertion/INTx emulation mode.
-
-Note that a device driver should always call free_irq() on the MSI vector
-that it has done request_irq() on before calling this API. Failure to do
-so results in a BUG_ON() and a device will be left with MSI enabled and
-leaks its vector.
-
-5.2.3 MSI mode vs. legacy mode diagram
-
-The below diagram shows the events which switch the interrupt
-mode on the MSI-capable device function between MSI mode and
-PIN-IRQ assertion mode.

-Figure 1. MSI Mode vs. Legacy Mode
-
-In Figure 1, a device operates by default in legacy mode. Legacy
-in this context means PCI pin-irq assertion or PCI-Express INTx
-emulation. A successful MSI request (using pci_enable_msi()) switches
-a device's interrupt mode to MSI mode. A pre-assigned IOAPIC vector
-stored in dev->irq will be saved by the PCI subsystem and a new
-assigned MSI vector will replace dev->irq.
-
-To return back to its default mode, a device driver should always call
-pci_disable_msi() to undo the effect of pci_enable_msi(). Note that a
-device driver should always call free_irq() on the MSI vector it has
-done request_irq() on before calling pci_disable_msi(). Failure to do
-so results in a BUG_ON() and a device will be left with MSI enabled and
-leaks its vector. Otherwise, the PCI subsystem restores a device's
-dev->irq with a pre-assigned IOAPIC vector and marks the released
-MSI vector as unused.
-
-Once being marked as unused, there is no guarantee that the PCI
-subsystem will reserve this MSI vector for a device. Depending on
-the availability of current PCI vector resources and the number of
-MSI/MSI-X requests from other drivers, this MSI may be re-assigned.
-
-For the case where the PCI subsystem re-assigns this MSI vector to
-another driver, a request to switch back to MSI mode may result
-in being assigned a different MSI vector or a failure if no more
-vectors are available.
-
-5.3 Configuring for MSI-X support
-
-Due to the ability of the system software to configure each vector of
-the MSI-X capability structure with an independent message address
-and message data, the non-contiguous fashion in vector assignment of
-the existing Linux kernel has no impact on supporting multiple
-messages on an MSI-X capable device functions. To enable MSI-X on
-a device function's MSI-X capability structure requires its device
-driver to call the function pci_enable_msix() explicitly.
-
-The function pci_enable_msix(), once invoked, enables either
-all or nothing, depending on the current availability of PCI vector
-resources. If the PCI vector resources are available for the number
-of vectors requested by a device driver, this function will configure
-the MSI-X table of the MSI-X capability structure of a device with
-requested messages. To emphasize this reason, for example, a device
-may be capable for supporting the maximum of 32 vectors while its
-software driver usually may request 4 vectors. It is recommended
-that the device driver should call this function once during the
-initialization phase of the device driver.
-
-Unlike the function pci_enable_msi(), the function pci_enable_msix()
-does not replace the pre-assigned IOAPIC dev->irq with a new MSI
-vector because the PCI subsystem writes the 1:1 vector-to-entry mapping
-into the field vector of each element contained in a second argument.
-Note that the pre-assigned IOAPIC dev->irq is valid only if the device
-operates in PIN-IRQ assertion mode. In MSI-X mode, any attempt at
-using dev->irq by the device driver to request for interrupt service
-may result in unpredictable behavior.
-
-For each MSI-X vector granted, a device driver is responsible for calling
-other functions like request_irq(), enable_irq(), etc. to enable
-this vector with its corresponding interrupt service handler. It is
-a device driver's choice to assign all vectors with the same
-interrupt service handler or each vector with a unique interrupt
-service handler.
-
-5.3.1 Handling MMIO address space of MSI-X Table
-
-The PCI 3.0 specification has implementation notes that MMIO address
-space for a device's MSI-X structure should be isolated so that the
-software system can set different pages for controlling accesses to the
-MSI-X structure. The implementation of MSI support requires the PCI
-subsystem, not a device driver, to maintain full control of the MSI-X
-table/MSI-X PBA (Pending Bit Array) and MMIO address space of the MSI-X
-table/MSI-X PBA.  A device driver should not access the MMIO address
-space of the MSI-X table/MSI-X PBA.
-
-5.3.2 API pci_enable_msix
+Devices may support both MSI and MSI-X, but only one can be enabled at
+a time.
 
-int pci_enable_msix(struct pci_dev *dev, struct msix_entry *entries, int nvec)
 
-This API enables a device driver to request the PCI subsystem
-to enable MSI-X messages on its hardware device. Depending on
-the availability of PCI vectors resources, the PCI subsystem enables
-either all or none of the requested vectors.
+3. Why use MSIs?
+
+There are three reasons why using MSIs can give an advantage over
+traditional pin-based interrupts.
+
+Pin-based PCI interrupts are often shared amongst several devices.
+To support this, the kernel must call each interrupt handler associated
+with an interrupt, which leads to reduced performance for the system as
+a whole.  MSIs are never shared, so this problem cannot arise.
+
+When a device writes data to memory, then raises a pin-based interrupt,
+it is possible that the interrupt may arrive before all the data has
+arrived in memory (this becomes more likely with devices behind PCI-PCI
+bridges).  In order to ensure that all the data has arrived in memory,
+the interrupt handler must read a register on the device which raised
+the interrupt.  PCI transaction ordering rules require that all the data
+arrives in memory before the value can be returned from the register.
+Using MSIs avoids this problem as the interrupt-generating write cannot
+pass the data writes, so by the time the interrupt is raised, the driver
+knows that all the data has arrived in memory.
+
+PCI devices can only support a single pin-based interrupt per function.
+Often drivers have to query the device to find out what event has
+occurred, slowing down interrupt handling for the common case.  With
+MSIs, a device can support more interrupts, allowing each interrupt
+to be specialised to a different purpose.  One possible design gives
+infrequent conditions (such as errors) their own interrupt which allows
+the driver to handle the normal interrupt handling path more efficiently.
+Other possible designs include giving one interrupt to each packet queue
+in a network card or each port in a storage controller.
+
+
+4. How to use MSIs
+
+PCI devices are initialised to use pin-based interrupts.  The device
+driver has to set up the device to use MSI or MSI-X.  Not all machines
+support MSIs correctly, and for those machines, the APIs described below
+will simply fail and the device will continue to use pin-based interrupts.
+
+4.1 Include kernel support for MSIs
+
+To support MSI or MSI-X, the kernel must be built with the CONFIG_PCI_MSI
+option enabled.  This option is only available on some architectures,
+and it may depend on some other options also being set.  For example,
+on x86, you must also enable X86_UP_APIC or SMP in order to see the
+CONFIG_PCI_MSI option.
+
+4.2 Using MSI
+
+Most of the hard work is done for the driver in the PCI layer.  It simply
+has to request that the PCI layer set up the MSI capability for this
+device.
+
+4.2.1 pci_enable_msi
+
+int pci_enable_msi(struct pci_dev *dev)
+
+A successful call will allocate ONE interrupt to the device, regardless
+of how many MSIs the device supports.  The device will be switched from
+pin-based interrupt mode to MSI mode.  The dev->irq number is changed
+to a new number which represents the message signaled interrupt.
+This function should be called before the driver calls request_irq()
+since enabling MSIs disables the pin-based IRQ and the driver will not
+receive interrupts on the old interrupt.
+
+4.2.2 pci_enable_msi_block
+
+int pci_enable_msi_block(struct pci_dev *dev, int count)
+
+This variation on the above call allows a device driver to request multiple
+MSIs.  The MSI specification only allows interrupts to be allocated in
+powers of two, up to a maximum of 2^5 (32).
+
+If this function returns 0, it has succeeded in allocating at least as many
+interrupts as the driver requested (it may have allocated more in order
+to satisfy the power-of-two requirement).  In this case, the function
+enables MSI on this device and updates dev->irq to be the lowest of
+the new interrupts assigned to it.  The other interrupts assigned to
+the device are in the range dev->irq to dev->irq + count - 1.
+
+If this function returns a negative number, it indicates an error and
+the driver should not attempt to request any more MSI interrupts for
+this device.  If this function returns a positive number, it will be
+less than 'count' and indicate the number of interrupts that could have
+been allocated.  In neither case will the irq value have been
+updated, nor will the device have been switched into MSI mode.
+
+The device driver must decide what action to take if
+pci_enable_msi_block() returns a value less than the number asked for.
+Some devices can make use of fewer interrupts than the maximum they
+request; in this case the driver should call pci_enable_msi_block()
+again.  Note that it is not guaranteed to succeed, even when the
+'count' has been reduced to the value returned from a previous call to
+pci_enable_msi_block().  This is because there are multiple constraints
+on the number of vectors that can be allocated; pci_enable_msi_block()
+will return as soon as it finds any constraint that doesn't allow the
+call to succeed.
+
+4.2.3 pci_disable_msi
+
+void pci_disable_msi(struct pci_dev *dev)
 
-Argument 'dev' points to the device (pci_dev) structure.
+This function should be used to undo the effect of pci_enable_msi() or
+pci_enable_msi_block().  Calling it restores dev->irq to the pin-based
+interrupt number and frees the previously allocated message signaled
+interrupt(s).  The interrupt may subsequently be assigned to another
+device, so drivers should not cache the value of dev->irq.
 
-Argument 'entries' is a pointer to an array of msix_entry structs.
-The number of entries is indicated in argument 'nvec'.
-struct msix_entry is defined in /driver/pci/msi.h:
+A device driver must always call free_irq() on the interrupt(s)
+for which it has called request_irq() before calling this function.
+Failure to do so will result in a BUG_ON(), the device will be left with
+MSI enabled and will leak its vector.
+
+4.3 Using MSI-X
+
+The MSI-X capability is much more flexible than the MSI capability.
+It supports up to 2048 interrupts, each of which can be controlled
+independently.  To support this flexibility, drivers must use an array of
+`struct msix_entry':
 
 struct msix_entry {
 	u16 	vector; /* kernel uses to write alloc vector */
 	u16	entry; /* driver uses to specify entry */
 };
 
-A device driver is responsible for initializing the field 'entry' of
-each element with a unique entry supported by MSI-X table. Otherwise,
--EINVAL will be returned as a result. A successful return of zero
-indicates the PCI subsystem completed initializing each of the requested
-entries of the MSI-X table with message address and message data.
-Last but not least, the PCI subsystem will write the 1:1
-vector-to-entry mapping into the field 'vector' of each element. A
-device driver is responsible for keeping track of allocated MSI-X
-vectors in its internal data structure.
-
-A return of zero indicates that the number of MSI-X vectors was
-successfully allocated. A return of greater than zero indicates
-MSI-X vector shortage. Or a return of less than zero indicates
-a failure. This failure may be a result of duplicate entries
-specified in second argument, or a result of no available vector,
-or a result of failing to initialize MSI-X table entries.
-
-5.3.3 API pci_disable_msix
+This allows for the device to use these interrupts in a sparse fashion;
+for example it could use interrupts 3 and 1027 and allocate only a
+two-element array.  The driver is expected to fill in the 'entry' value
+in each element of the array to indicate which entries it wants the kernel
+to assign interrupts for.  It is invalid to fill in two entries with the
+same number.
+
+4.3.1 pci_enable_msix
+
+int pci_enable_msix(struct pci_dev *dev, struct msix_entry *entries, int nvec)
+
+Calling this function asks the PCI subsystem to allocate 'nvec' MSIs.
+The 'entries' argument is a pointer to an array of msix_entry structs
+which should be at least 'nvec' entries in size.  On success, the
+function will return 0 and the device will have been switched into
+MSI-X interrupt mode.  The 'vector' elements in each entry will have
+been filled in with the interrupt number.  The driver should then call
+request_irq() for each 'vector' that it decides to use.
+
+If this function returns a negative number, it indicates an error and
+the driver should not attempt to allocate any more MSI-X interrupts for
+this device.  If it returns a positive number, it indicates the maximum
+number of interrupt vectors that could have been allocated. See example
+below.
+
+This function, in contrast with pci_enable_msi(), does not adjust
+dev->irq.  The device will not generate interrupts for this interrupt
+number once MSI-X is enabled.  The device driver is responsible for
+keeping track of the interrupts assigned to the MSI-X vectors so it can
+free them again later.
+
+Device drivers should normally call this function once per device
+during the initialization phase.
+
+It is ideal if drivers can cope with a variable number of MSI-X interrupts,
+there are many reasons why the platform may not be able to provide the
+exact number a driver asks for.
+
+A request loop to achieve that might look like:
+
+static int foo_driver_enable_msix(struct foo_adapter *adapter, int nvec)
+{
+	while (nvec >= FOO_DRIVER_MINIMUM_NVEC) {
+		rc = pci_enable_msix(adapter->pdev,
+				     adapter->msix_entries, nvec);
+		if (rc > 0)
+			nvec = rc;
+		else
+			return rc;
+	}
+
+	return -ENOSPC;
+}
+
+4.3.2 pci_disable_msix
 
 void pci_disable_msix(struct pci_dev *dev)
 
-This API should always be used to undo the effect of pci_enable_msix()
-when a device driver is unloading. Note that a device driver should
-always call free_irq() on all MSI-X vectors it has done request_irq()
-on before calling this API. Failure to do so results in a BUG_ON() and
-a device will be left with MSI-X enabled and leaks its vectors.
-
-5.3.4 MSI-X mode vs. legacy mode diagram
-
-The below diagram shows the events which switch the interrupt
-mode on the MSI-X capable device function between MSI-X mode and
-PIN-IRQ assertion mode (legacy).

-
-Figure 2. MSI-X Mode vs. Legacy Mode
-
-In Figure 2, a device operates by default in legacy mode. A
-successful MSI-X request (using pci_enable_msix()) switches a
-device's interrupt mode to MSI-X mode. A pre-assigned IOAPIC vector
-stored in dev->irq will be saved by the PCI subsystem; however,
-unlike MSI mode, the PCI subsystem will not replace dev->irq with
-assigned MSI-X vector because the PCI subsystem already writes the 1:1
-vector-to-entry mapping into the field 'vector' of each element
-specified in second argument.
-
-To return back to its default mode, a device driver should always call
-pci_disable_msix() to undo the effect of pci_enable_msix(). Note that
-a device driver should always call free_irq() on all MSI-X vectors it
-has done request_irq() on before calling pci_disable_msix(). Failure
-to do so results in a BUG_ON() and a device will be left with MSI-X
-enabled and leaks its vectors. Otherwise, the PCI subsystem switches a
-device function's interrupt mode from MSI-X mode to legacy mode and
-marks all allocated MSI-X vectors as unused.
-
-Once being marked as unused, there is no guarantee that the PCI
-subsystem will reserve these MSI-X vectors for a device. Depending on
-the availability of current PCI vector resources and the number of
-MSI/MSI-X requests from other drivers, these MSI-X vectors may be
-re-assigned.
-
-For the case where the PCI subsystem re-assigned these MSI-X vectors
-to other drivers, a request to switch back to MSI-X mode may result
-being assigned with another set of MSI-X vectors or a failure if no
-more vectors are available.
-
-5.4 Handling function implementing both MSI and MSI-X capabilities
-
-For the case where a function implements both MSI and MSI-X
-capabilities, the PCI subsystem enables a device to run either in MSI
-mode or MSI-X mode but not both. A device driver determines whether it
-wants MSI or MSI-X enabled on its hardware device. Once a device
-driver requests for MSI, for example, it is prohibited from requesting
-MSI-X; in other words, a device driver is not permitted to ping-pong
-between MSI mod MSI-X mode during a run-time.
-
-5.5 Hardware requirements for MSI/MSI-X support
-
-MSI/MSI-X support requires support from both system hardware and
-individual hardware device functions.
-
-5.5.1 Required x86 hardware support
-
-Since the target of MSI address is the local APIC CPU, enabling
-MSI/MSI-X support in the Linux kernel is dependent on whether existing
-system hardware supports local APIC. Users should verify that their
-system supports local APIC operation by testing that it runs when
-CONFIG_X86_LOCAL_APIC=y.
-
-In SMP environment, CONFIG_X86_LOCAL_APIC is automatically set;
-however, in UP environment, users must manually set
-CONFIG_X86_LOCAL_APIC. Once CONFIG_X86_LOCAL_APIC=y, setting
-CONFIG_PCI_MSI enables the VECTOR based scheme and the option for
-MSI-capable device drivers to selectively enable MSI/MSI-X.
-
-Note that CONFIG_X86_IO_APIC setting is irrelevant because MSI/MSI-X
-vector is allocated new during runtime and MSI/MSI-X support does not
-depend on BIOS support. This key independency enables MSI/MSI-X
-support on future IOxAPIC free platforms.
-
-5.5.2 Device hardware support
-
-The hardware device function supports MSI by indicating the
-MSI/MSI-X capability structure on its PCI capability list. By
-default, this capability structure will not be initialized by
-the kernel to enable MSI during the system boot. In other words,
-the device function is running on its default pin assertion mode.
-Note that in many cases the hardware supporting MSI have bugs,
-which may result in system hangs. The software driver of specific
-MSI-capable hardware is responsible for deciding whether to call
-pci_enable_msi or not. A return of zero indicates the kernel
-successfully initialized the MSI/MSI-X capability structure of the
-device function. The device function is now running on MSI/MSI-X mode.
-
-5.6 How to tell whether MSI/MSI-X is enabled on device function
-
-At the driver level, a return of zero from the function call of
-pci_enable_msi()/pci_enable_msix() indicates to a device driver that
-its device function is initialized successfully and ready to run in
-MSI/MSI-X mode.
-
-At the user level, users can use the command 'cat /proc/interrupts'
-to display the vectors allocated for devices and their interrupt
-MSI/MSI-X modes ("PCI-MSI"/"PCI-MSI-X"). Below shows MSI mode is
-enabled on a SCSI Adaptec 39320D Ultra320 controller.

-6. MSI quirks
-
-Several PCI chipsets or devices are known to not support MSI.
-The PCI stack provides 3 possible levels of MSI disabling:
-* on a single device
-* on all devices behind a specific bridge
-* globally
-
-6.1. Disabling MSI on a single device
-
-Under some circumstances it might be required to disable MSI on a
-single device.  This may be achieved by either not calling pci_enable_msi()
-or all, or setting the pci_dev->no_msi flag before (most of the time
-in a quirk).
-
-6.2. Disabling MSI below a bridge
-
-The vast majority of MSI quirks are required by PCI bridges not
-being able to route MSI between busses. In this case, MSI have to be
-disabled on all devices behind this bridge. It is achieves by setting
-the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge
-subordinate bus. There is no need to set the same flag on bridges that
-are below the broken bridge. When pci_enable_msi() is called to enable
-MSI on a device, pci_msi_supported() takes care of checking the NO_MSI
-flag in all parent busses of the device.
-
-Some bridges actually support dynamic MSI support enabling/disabling
-by changing some bits in their PCI configuration space (especially
-the Hypertransport chipsets such as the nVidia nForce and Serverworks
-HT2000). It may then be required to update the NO_MSI flag on the
-corresponding devices in the sysfs hierarchy. To enable MSI support
-on device "0000:00:0e", do:
-
-	echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus
-
-To disable MSI support, echo 0 instead of 1. Note that it should be
-used with caution since changing this value might break interrupts.
-
-6.3. Disabling MSI globally
-
-Some extreme cases may require to disable MSI globally on the system.
-For now, the only known case is a Serverworks PCI-X chipsets (MSI are
-not supported on several busses that are not all connected to the
-chipset in the Linux PCI hierarchy). In the vast majority of other
-cases, disabling only behind a specific bridge is enough.
-
-For debugging purpose, the user may also pass pci=nomsi on the kernel
-command-line to explicitly disable MSI globally. But, once the appro-
-priate quirks are added to the kernel, this option should not be
-required anymore.
-
-6.4. Finding why MSI cannot be enabled on a device
-
-Assuming that MSI are not enabled on a device, you should look at
-dmesg to find messages that quirks may output when disabling MSI
-on some devices, some bridges or even globally.
-Then, lspci -t gives the list of bridges above a device. Reading
-/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI
-are enabled (1) or disabled (0). In 0 is found in a single bridge
-msi_bus file above the device, MSI cannot be enabled.
-
-7. FAQ
-
-Q1. Are there any limitations on using the MSI?
-
-A1. If the PCI device supports MSI and conforms to the
-specification and the platform supports the APIC local bus,
-then using MSI should work.
-
-Q2. Will it work on all the Pentium processors (P3, P4, Xeon,
-AMD processors)? In P3 IPI's are transmitted on the APIC local
-bus and in P4 and Xeon they are transmitted on the system
-bus. Are there any implications with this?
-
-A2. MSI support enables a PCI device sending an inbound
-memory write (0xfeexxxxx as target address) on its PCI bus
-directly to the FSB. Since the message address has a
-redirection hint bit cleared, it should work.
-
-Q3. The target address 0xfeexxxxx will be translated by the
-Host Bridge into an interrupt message. Are there any
-limitations on the chipsets such as Intel 8xx, Intel e7xxx,
-or VIA?
-
-A3. If these chipsets support an inbound memory write with
-target address set as 0xfeexxxxx, as conformed to PCI
-specification 2.3 or latest, then it should work.
-
-Q4. From the driver point of view, if the MSI is lost because
-of errors occurring during inbound memory write, then it may
-wait forever. Is there a mechanism for it to recover?
-
-A4. Since the target of the transaction is an inbound memory
-write, all transaction termination conditions (Retry,
-Master-Abort, Target-Abort, or normal completion) are
-supported. A device sending an MSI must abide by all the PCI
-rules and conditions regarding that inbound memory write. So,
-if a retry is signaled it must retry, etc... We believe that
-the recommendation for Abort is also a retry (refer to PCI
-specification 2.3 or latest).
+This API should be used to undo the effect of pci_enable_msix().  It frees
+the previously allocated message signaled interrupts.  The interrupts may
+subsequently be assigned to another device, so drivers should not cache
+the value of the 'vector' elements over a call to pci_disable_msix().
+
+A device driver must always call free_irq() on the interrupt(s)
+for which it has called request_irq() before calling this function.
+Failure to do so will result in a BUG_ON(), the device will be left with
+MSI enabled and will leak its vector.
+
+4.3.3 The MSI-X Table
+
+The MSI-X capability specifies a BAR and offset within that BAR for the
+MSI-X Table.  This address is mapped by the PCI subsystem, and should not
+be accessed directly by the device driver.  If the driver wishes to
+mask or unmask an interrupt, it should call disable_irq() / enable_irq().
+
+4.4 Handling devices implementing both MSI and MSI-X capabilities
+
+If a device implements both MSI and MSI-X capabilities, it can
+run in either MSI mode or MSI-X mode but not both simultaneously.
+This is a requirement of the PCI spec, and it is enforced by the
+PCI layer.  Calling pci_enable_msi() when MSI-X is already enabled or
+pci_enable_msix() when MSI is already enabled will result in an error.
+If a device driver wishes to switch between MSI and MSI-X at runtime,
+it must first quiesce the device, then switch it back to pin-interrupt
+mode, before calling pci_enable_msi() or pci_enable_msix() and resuming
+operation.  This is not expected to be a common operation but may be
+useful for debugging or testing during development.
+
+4.5 Considerations when using MSIs
+
+4.5.1 Choosing between MSI-X and MSI
+
+If your device supports both MSI-X and MSI capabilities, you should use
+the MSI-X facilities in preference to the MSI facilities.  As mentioned
+above, MSI-X supports any number of interrupts between 1 and 2048.
+In constrast, MSI is restricted to a maximum of 32 interrupts (and
+must be a power of two).  In addition, the MSI interrupt vectors must
+be allocated consecutively, so the system may not be able to allocate
+as many vectors for MSI as it could for MSI-X.  On some platforms, MSI
+interrupts must all be targetted at the same set of CPUs whereas MSI-X
+interrupts can all be targetted at different CPUs.

+Most device drivers have a per-device spinlock which is taken in the
+interrupt handler.  With pin-based interrupts or a single MSI, it is not
+necessary to disable interrupts (Linux guarantees the same interrupt will
+not be re-entered).  If a device uses multiple interrupts, the driver
+must disable interrupts while the lock is held.  If the device sends
+a different interrupt, the driver will deadlock trying to recursively
+acquire the spinlock.
+
+There are two solutions.  The first is to take the lock with
+spin_lock_irqsave() or spin_lock_irq() (see
+Documentation/DocBook/kernel-locking).  The second is to specify
+IRQF_DISABLED to request_irq() so that the kernel runs the entire
+interrupt routine with interrupts disabled.
+
+If your MSI interrupt routine does not hold the lock for the whole time
+it is running, the first solution may be best.  The second solution is
+normally preferred as it avoids making two transitions from interrupt
+disabled to enabled and back again.
+
+4.6 How to tell whether MSI/MSI-X is enabled on a device
+
+Using 'lspci -v' (as root) may show some devices with "MSI", "Message
+Signalled Interrupts" or "MSI-X" capabilities.  Each of these capabilities
+has an 'Enable' flag which will be followed with either "+" (enabled)
+or "-" (disabled).
+
+
+5. MSI quirks
+
+Several PCI chipsets or devices are known not to support MSIs.
+The PCI stack provides three ways to disable MSIs:
+
+1. globally
+2. on all devices behind a specific bridge
+3. on a single device
+
+5.1. Disabling MSIs globally
+
+Some host chipsets simply don't support MSIs properly.  If we're
+lucky, the manufacturer knows this and has indicated it in the ACPI
+FADT table.  In this case, Linux will automatically disable MSIs.
+Some boards don't include this information in the table and so we have
+to detect them ourselves.  The complete list of these is found near the
+quirk_disable_all_msi() function in drivers/pci/quirks.c.
+
+If you have a board which has problems with MSIs, you can pass pci=nomsi
+on the kernel command line to disable MSIs on all devices.  It would be
+in your best interests to report the problem to linux-pci@vger.kernel.org
+including a full 'lspci -v' so we can add the quirks to the kernel.
+
+5.2. Disabling MSIs below a bridge
+
+Some PCI bridges are not able to route MSIs between busses properly.
+In this case, MSIs must be disabled on all devices behind the bridge.
+
+Some bridges allow you to enable MSIs by changing some bits in their
+PCI configuration space (especially the Hypertransport chipsets such
+as the nVidia nForce and Serverworks HT2000).  As with host chipsets,
+Linux mostly knows about them and automatically enables MSIs if it can.
+If you have a bridge which Linux doesn't yet know about, you can enable
+MSIs in configuration space using whatever method you know works, then
+enable MSIs on that bridge by doing:
+
+       echo 1 > /sys/bus/pci/devices/$bridge/msi_bus
+
+where $bridge is the PCI address of the bridge you've enabled (eg
+0000:00:0e.0).
+
+To disable MSIs, echo 0 instead of 1.  Changing this value should be
+done with caution as it can break interrupt handling for all devices
+below this bridge.
+
+Again, please notify linux-pci@vger.kernel.org of any bridges that need
+special handling.
+
+5.3. Disabling MSIs on a single device
+
+Some devices are known to have faulty MSI implementations.  Usually this
+is handled in the individual device driver but occasionally it's necessary
+to handle this with a quirk.  Some drivers have an option to disable use
+of MSI.  While this is a convenient workaround for the driver author,
+it is not good practise, and should not be emulated.
+
+5.4. Finding why MSIs are disabled on a device
+
+From the above three sections, you can see that there are many reasons
+why MSIs may not be enabled for a given device.  Your first step should
+be to examine your dmesg carefully to determine whether MSIs are enabled
+for your machine.  You should also check your .config to be sure you
+have enabled CONFIG_PCI_MSI.
+
+Then, 'lspci -t' gives the list of bridges above a device.  Reading
+/sys/bus/pci/devices/*/msi_bus will tell you whether MSI are enabled (1)
+or disabled (0).  If 0 is found in any of the msi_bus files belonging
+to bridges between the PCI root and the device, MSIs are disabled.
+
+It is also worth checking the device driver to see whether it supports MSIs.
+For example, it may contain calls to pci_enable_msi(), pci_enable_msix() or
+pci_enable_msi_block().

+		PCI Express I/O Virtualization Howto
+		Copyright (C) 2009 Intel Corporation
+		    Yu Zhao <yu.zhao@intel.com>
+
+
+1. Overview
+
+1.1 What is SR-IOV
+
+Single Root I/O Virtualization (SR-IOV) is a PCI Express Extended
+capability which makes one physical device appear as multiple virtual
+devices. The physical device is referred to as Physical Function (PF)
+while the virtual devices are referred to as Virtual Functions (VF).
+Allocation of the VF can be dynamically controlled by the PF via
+registers encapsulated in the capability. By default, this feature is
+not enabled and the PF behaves as traditional PCIe device. Once it's
+turned on, each VF's PCI configuration space can be accessed by its own
+Bus, Device and Function Number (Routing ID). And each VF also has PCI
+Memory Space, which is used to map its register set. VF device driver
+operates on the register set so it can be functional and appear as a
+real existing PCI device.
+
+2. User Guide
+
+2.1 How can I enable SR-IOV capability
+
+The device driver (PF driver) will control the enabling and disabling
+of the capability via API provided by SR-IOV core. If the hardware
+has SR-IOV capability, loading its PF driver would enable it and all
+VFs associated with the PF.
+
+2.2 How can I use the Virtual Functions
+
+The VF is treated as hot-plugged PCI devices in the kernel, so they
+should be able to work in the same way as real PCI devices. The VF
+requires device driver that is same as a normal PCI device's.
+
+3. Developer Guide
+
+3.1 SR-IOV API
+
+To enable SR-IOV capability:
+	int pci_enable_sriov(struct pci_dev *dev, int nr_virtfn);
+	'nr_virtfn' is number of VFs to be enabled.
+
+To disable SR-IOV capability:
+	void pci_disable_sriov(struct pci_dev *dev);
+
+To notify SR-IOV core of Virtual Function Migration:
+	irqreturn_t pci_sriov_migration(struct pci_dev *dev);
+
+3.2 Usage example
+
+Following piece of code illustrates the usage of the SR-IOV API.
+
+static int __devinit dev_probe(struct pci_dev *dev, const struct pci_device_id *id)
+{
+	pci_enable_sriov(dev, NR_VIRTFN);
+
+	...
+
+	return 0;
+}
+
+static void __devexit dev_remove(struct pci_dev *dev)
+{
+	pci_disable_sriov(dev);
+
+	...
+}
+
+static int dev_suspend(struct pci_dev *dev, pm_message_t state)
+{
+	...
+
+	return 0;
+}
+
+static int dev_resume(struct pci_dev *dev)
+{
+	...
+
+	return 0;
+}
+
+static void dev_shutdown(struct pci_dev *dev)
+{
+	...
+}
+
+static struct pci_driver dev_driver = {
+	.name =		"SR-IOV Physical Function driver",
+	.id_table =	dev_id_table,
+	.probe =	dev_probe,
+	.remove =	__devexit_p(dev_remove),
+	.suspend =	dev_suspend,
+	.resume =	dev_resume,
+	.shutdown =	dev_shutdown,

+Smack Netlabel Exceptions
+
+You will often find that your labeled application has to talk to the outside,
+unlabeled world. To do this there's a special file /smack/netlabel where you can
+add some exceptions in the form of :
+@IP1	   LABEL1 or
+@IP2/MASK  LABEL2
+
+It means that your application will have unlabeled access to @IP1 if it has
+write access on LABEL1, and access to the subnet @IP2/MASK if it has write
+access on LABEL2.
+
+Entries in the /smack/netlabel file are matched by longest mask first, like in
+classless IPv4 routing.
+
+A special label '@' and an option '-CIPSO' can be used there :
+@      means Internet, any application with any label has access to it
+-CIPSO means standard CIPSO networking
+
+If you don't know what CIPSO is and don't plan to use it, you can just do :
+echo 127.0.0.1 -CIPSO > /smack/netlabel
+echo 0.0.0.0/0 @      > /smack/netlabel
+
+If you use CIPSO on your 192.168.0.0/16 local network and need also unlabeled
+Internet access, you can have :
+echo 127.0.0.1      -CIPSO > /smack/netlabel

-Apollo PLE 133 Chipset VT8601A North Bridge Datasheet, Rev. 1.82, October 22,
-2001, available from VIA:
-
-	http://www.viavpsd.com/product/6/15/DS8601A182.pdf
-
-The datasheet is incomplete, some registers that need to be programmed are not
-explained at all and important bits are listed as "reserved". But you really
-need the datasheet to understand the code.  "p. xxx" comments refer to page
-numbers of this document.
-
-XFree/XOrg drivers are available and of good quality, looking at the code
-there is a good idea if the datasheet does not provide enough information
-or if the datasheet seems to be wrong.

-#   Sample fb.modes file
-#
-#	Provides an incomplete list of working modes for
-#	the cyberblade/i1 graphics core.
-#
-#	The value 4294967256 is used instead of -40. Of course, -40 is not
-#	a really reasonable value, but chip design does not always follow
-#	logic. Believe me, it's ok, and it's the way the BIOS does it.
-#
-#	fbset requires 4294967256 in fb.modes and -40 as an argument to
-#	the -t parameter. That's also not too reasonable, and it might change
-#	in the future or might even be differt for your current version.

-Speed
-=====
-
-CyBlaFB is much faster than tridentfb and vesafb. Compare the performance data
-for mode 1280x1024-[8,16,32]@61 Hz.
-
-Test 1: Cat a file with 2000 lines of 0 characters.
-Test 2: Cat a file with 2000 lines of 80 characters.
-Test 3: Cat a file with 2000 lines of 160 characters.
-
-All values show system time use in seconds, kernel 2.6.12 was used for
-the measurements. 2.6.13 is a bit slower, 2.6.14 hopefully will include a
-patch that speeds up kernel bitblitting a lot ( > 20%).

-TODO / Missing features
-=======================
-
-Verify LCD stuff		"stretch" and "center" options are
-				completely untested ... this code needs to be
-				verified. As I don't have access to such
-				hardware, please contact me if you are
-				willing run some tests.
-
-Interlaced video modes		The reason that interleaved
-				modes are disabled is that I do not know
-				the meaning of the vertical interlace
-				parameter. Also the datasheet mentions a
-				bit d8 of a horizontal interlace parameter,
-				but nowhere the lower 8 bits. Please help
-				if you can.
-
-low-res double scan modes	Who needs it?
-
-accelerated color blitting	Who needs it? The console driver does use color
-				blitting for nothing but drawing the penguine,
-				everything else is done using color expanding
-				blitting of 1bpp character bitmaps.
-
-ioctls				Who needs it?
-
-TV-out				Will be done later. Use "vga= " at boot time
-				to set a suitable video mode.
-
-???				Feel free to contact me if you have any

-CyBlaFB is a framebuffer driver for the Cyberblade/i1 graphics core integrated
-into the VIA Apollo PLE133 (aka vt8601) south bridge. It is developed and
-tested using a VIA EPIA 5000 board.
-
-Cyblafb - compiled into the kernel or as a module?
-==================================================
-
-You might compile cyblafb either as a module or compile it permanently into the
-kernel.
-
-Unless you have a real reason to do so you should not compile both vesafb and
-cyblafb permanently into the kernel. It's possible and it helps during the
-developement cycle, but it's useless and will at least block some otherwise
-usefull memory for ordinary users.
-
-Selecting Modes
-===============
-
-	Startup Mode
-	============
-
-	First of all, you might use the "vga=???" boot parameter as it is
-	documented in vesafb.txt and svga.txt. Cyblafb will detect the video
-	mode selected and will use the geometry and timings found by
-	inspecting the hardware registers.
-
-		video=cyblafb vga=0x317
-
-	Alternatively you might use a combination of the mode, ref and bpp
-	parameters. If you compiled the driver into the kernel, add something
-	like this to the kernel command line:
-
-		video=cyblafb:1280x1024,bpp=16,ref=50 ...
-
-	If you compiled the driver as a module, the same mode would be
-	selected by the following command:
-
-		modprobe cyblafb mode=1280x1024 bpp=16 ref=50 ...
-
-	None of the modes possible to select as startup modes are affected by
-	the problems described at the end of the next subsection.
-
-	For all startup modes cyblafb chooses a virtual x resolution of 2048,
-	the only exception is mode 1280x1024 in combination with 32 bpp. This
-	allows ywrap scrolling for all those modes if rotation is 0 or 2, and
-	also fast scrolling if rotation is 1 or 3. The default virtual y reso-
-	lution is 4096 for bpp == 8, 2048 for bpp==16 and 1024 for bpp == 32,
-	again with the only exception of 1280x1024 at 32 bpp.
-
-	Please do set your video memory size to 8 Mb in the Bios setup. Other
-	values will work, but performace is decreased for a lot of modes.
-
-	Mode changes using fbset
-	========================
-
-	You might use fbset to change the video mode, see "man fbset". Cyblafb
-	generally does assume that you know what you are doing. But it does
-	some checks, especially those that are needed to prevent you from
-	damaging your hardware.
-
-		- only 8, 16, 24 and 32 bpp video modes are accepted
-		- interlaced video modes are not accepted
-		- double scan video modes are not accepted
-		- if a flat panel is found, cyblafb does not allow you
-		  to program a resolution higher than the physical
-		  resolution of the flat panel monitor
-		- cyblafb does not allow vclk to exceed 230 MHz. As 32 bpp
-		  and (currently) 24 bit modes use a doubled vclk internally,
-		  the dotclock limit as seen by fbset is 115 MHz for those
-		  modes and 230 MHz for 8 and 16 bpp modes.
-		- cyblafb will allow you to select very high resolutions as
-		  long as the hardware can be programmed to these modes. The
-		  documented limit 1600x1200 is not enforced, but don't expect
-		  perfect signal quality.
-
-	Any request that violates the rules given above will be either changed
-	to something the hardware supports or an error value will be returned.
-
-	If you program a virtual y resolution higher than the hardware limit,
-	cyblafb will silently decrease that value to the highest possible
-	value. The same is true for a virtual x resolution that is not
-	supported by the hardware. Cyblafb tries to adapt vyres first because
-	vxres decides if ywrap scrolling is possible or not.
-
-	Attempts to disable acceleration are ignored, I believe that this is
-	safe.
-
-	Some video modes that should work do not work as expected. If you use
-	the standard fb.modes, fbset 640x480-60 will program that mode, but
-	you will see a vertical area, about two characters wide, with only
-	much darker characters than the other characters on the screen.
-	Cyblafb does allow that mode to be set, as it does not violate the
-	official specifications. It would need a lot of code to reliably sort
-	out all invalid modes, playing around with the margin values will
-	give a valid mode quickly. And if cyblafb would detect such an invalid
-	mode, should it silently alter the requested values or should it
-	report an error? Both options have some pros and cons. As stated
-	above, none of the startup modes are affected, and if you set
-	verbosity to 1 or higher, cyblafb will print the fbset command that
-	would be needed to program that mode using fbset.
-
-
-Other Parameters
-================
-
-
-crt		don't autodetect, assume monitor connected to
-		standard VGA connector
-
-fp		don't autodetect, assume flat panel display
-		connected to flat panel monitor interface
-
-nativex 	inform driver about native x resolution of
-		flat panel monitor connected to special
-		interface (should be autodetected)
-
-stretch 	stretch image to adapt low resolution modes to
-		higer resolutions of flat panel monitors
-		connected to special interface
-
-center		center image to adapt low resolution modes to
-		higer resolutions of flat panel monitors
-		connected to special interface
-
-memsize 	use if autodetected memsize is wrong ...
-		should never be necessary
-
-nopcirr 	disable PCI read retry
-nopciwr 	disable PCI write retry
-nopcirb 	disable PCI read bursts
-nopciwb 	disable PCI write bursts
-
-bpp		bpp for specified modes
-		valid values: 8 || 16 || 24 || 32
-
-ref		refresh rate for specified mode
-		valid values: 50 <= ref <= 85
-
-mode		640x480 or 800x600 or 1024x768 or 1280x1024
-		if not specified, the startup mode will be detected
-		and used, so you might also use the vga=??? parameter
-		described in vesafb.txt. If you do not specify a mode,
-		bpp and ref parameters are ignored.
-
-verbosity	0 is the default, increase to at least 2 for every
-		bug report!
-
-Development hints
-=================
-
-It's much faster do compile a module and to load the new version after
-unloading the old module than to compile a new kernel and to reboot. So if you
-try to work on cyblafb, it might be a good idea to use cyblafb as a module.
-In real life, fast often means dangerous, and that's also the case here. If
-you introduce a serious bug when cyblafb is compiled into the kernel, the
-kernel will lock or oops with a high probability before the file system is
-mounted, and the danger for your data is low. If you load a broken own version
-of cyblafb on a running system, the danger for the integrity of the file
-system is much higher as you might need a hard reset afterwards. Decide
-yourself.
-
-Module unloading, the vfb method
-================================
-
-If you want to unload/reload cyblafb using the virtual framebuffer, you need
-to enable vfb support in the kernel first. After that, load the modules as
-shown below:
-
-	modprobe vfb vfb_enable=1
-	modprobe fbcon
-	modprobe cyblafb
-	fbset -fb /dev/fb1 1280x1024-60 -vyres 2662
-	con2fb /dev/fb1 /dev/tty1
-	...
-
-If you now made some changes to cyblafb and want to reload it, you might do it
-as show below:
-
-	con2fb /dev/fb0 /dev/tty1
-	...
-	rmmod cyblafb
-	modprobe cyblafb
-	con2fb /dev/fb1 /dev/tty1
-	...
-
-Of course, you might choose another mode, and most certainly you also want to
-map some other /dev/tty* to the real framebuffer device. You might also choose
-to compile fbcon as a kernel module or place it permanently in the kernel.
-
-I do not know of any way to unload fbcon, and fbcon will prevent the
-framebuffer device loaded first from unloading. [If there is a way, then
-please add a description here!]
-
-Module unloading, the vesafb method
-===================================
-
-Configure the kernel:
-
-	<*> Support for frame buffer devices
-	[*]   VESA VGA graphics support
-	<M>   Cyberblade/i1 support
-
-Add e.g. "video=vesafb:ypan vga=0x307" to the kernel parameters. The ypan
-parameter is important, choose any vga parameter you like as long as it is
-a graphics mode.
-

-      - the vesafb parameter has been removed as I decided to allow the
-      	feature without any special parameter.
-
-      - Cyblafb does not use the vga style of panning any longer, now the
-      	"right view" register in the graphics engine IO space is used. Without
-	that change it was impossible to use all available memory, and without
-	access to all available memory it is impossible to ywrap.
-
-      - The imageblit function now uses hardware acceleration for all font
-        widths. Hardware blitting across pixel column 2048 is broken in the
-	cyberblade/i1 graphics core, but we work around that hardware bug.
-
-      - modes with vxres != xres are supported now.
-
-      - ywrap scrolling is supported now and the default. This is a big
-        performance gain.
-
-      - default video modes use vyres > yres and vxres > xres to allow
-        almost optimal scrolling speed for normal and rotated screens
-
-      - some features mainly usefull for debugging the upper layers of the
-        framebuffer system have been added, have a look at the code
-
-      - fixed: Oops after unloading cyblafb when reading /proc/io*
-
-      - we work around some bugs of the higher framebuffer layers.

-I tried the following framebuffer drivers:
-
-	- TRIDENTFB is full of bugs. Acceleration is broken for Blade3D
-	  graphics cores like the cyberblade/i1. It claims to support a great
-	  number of devices, but documentation for most of these devices is
-	  unfortunately not available. There is _no_ reason to use tridentfb
-	  for cyberblade/i1 + CRT users. VESAFB is faster, and the one
-	  advantage, mode switching, is broken in tridentfb.
-
-	- VESAFB is used by many distributions as a standard. Vesafb does
-	  not support mode switching. VESAFB is a bit faster than the working
-	  configurations of TRIDENTFB, but it is still too slow, even if you
-	  use ypan.
-
-	- EPIAFB (you'll find it on sourceforge) supports the Cyberblade/i1
-	  graphics core, but it still has serious bugs and developement seems
-	  to have stopped. This is the one driver with TV-out support. If you
-	  do need this feature, try epiafb.
-
-None of these drivers was a real option for me.
-
-I believe that is unreasonable to change code that announces to support 20
-devices if I only have more or less sufficient documentation for exactly one
-of these. The risk of breaking device foo while fixing device bar is too high.
-
-So I decided to start CyBlaFB as a stripped down tridentfb.
-
-All code specific to other Trident chips has been removed. After that there
-were a lot of cosmetic changes to increase the readability of the code. All
-register names were changed to those mnemonics used in the datasheet. Function
-and macro names were changed if they hindered easy understanding of the code.
-
-After that I debugged the code and implemented some new features. I'll try to
-give a little summary of the main changes:
-
-	- calculation of vertical and horizontal timings was fixed
-
-	- video signal quality has been improved dramatically
-
-	- acceleration:
-
-		- fillrect and copyarea were fixed and reenabled
-
-		- color expanding imageblit was newly implemented, color
-		  imageblit (only used to draw the penguine) still uses the
-		  generic code.
-
-		- init of the acceleration engine was improved and moved to a
-		  place where it really works ...
-
-		- sync function has a timeout now and tries to reset and
-		  reinit the accel engine if necessary
-
-		- fewer slow copyarea calls when doing ypan scrolling by using
-		  undocumented bit d21 of screen start address stored in
-		  CR2B[5]. BIOS does use it also, so this should be safe.
-
-	- cyblafb rejects any attempt to set modes that would cause vclk
-	  values above reasonable 230 MHz. 32bit modes use a clock
-	  multiplicator of 2, so fbset does show the correct values for
-	  pixclock but not for vclk in this case. The fbset limit is 115 MHz
-	  for 32 bpp modes.
-
-	- cyblafb rejects modes known to be broken or unimplemented (all
-	  interlaced modes, all doublescan modes for now)
-
-	- cyblafb now works independant of the video mode in effect at startup
-	  time (tridentfb does not init all needed registers to reasonable
-	  values)
-
-	- switching between video modes does work reliably now
-
-	- the first video mode now is the one selected on startup using the
-	  vga=???? mechanism or any of
-		- 640x480, 800x600, 1024x768, 1280x1024
-		- 8, 16, 24 or 32 bpp
-		- refresh between 50 Hz and 85 Hz, 1 Hz steps (1280x1024-32
-		  is limited to 63Hz)
-
-	- pci retry and pci burst mode are settable (try to disable if you
-	  experience latency problems)
-
-	- built as a module cyblafb might be unloaded and reloaded using
-	  the vfb module and con2vt or might be used together with vesafb

-What:	old static regulatory information and ieee80211_regdom module parameter
-When:	2.6.29
+What:	The ieee80211_regdom module parameter
+When:	March 2010 / desktop catchup
+
+Why:	This was inherited by the CONFIG_WIRELESS_OLD_REGULATORY code,
+	and currently serves as an option for users to define an
+	ISO / IEC 3166 alpha2 code for the country they are currently
+	present in. Although there are userspace API replacements for this
+	through nl80211 distributions haven't yet caught up with implementing
+	decent alternatives through standard GUIs. Although available as an
+	option through iw or wpa_supplicant its just a matter of time before
+	distributions pick up good GUI options for this. The ideal solution
+	would actually consist of intelligent designs which would do this for
+	the user automatically even when travelling through different countries.
+	Until then we leave this module parameter as a compromise.
+
+	When userspace improves with reasonable widely-available alternatives for
+	this we will no longer need this module parameter. This entry hopes that
+	by the super-futuristically looking date of "March 2010" we will have
+	such replacements widely available.

+What:	CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information
+When:	March 2010 / desktop catchup
+
 Why:	The old regulatory infrastructure has been replaced with a new one
 	which does not require statically defined regulatory domains. We do
 	not want to keep static regulatory domains in the kernel due to the
 	the dynamic nature of regulatory law and localization. We kept around
 	the old static definitions for the regulatory domains of:
+
 		* US
 		* JP
 		* EU
+
 	and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
-	set. We also kept around the ieee80211_regdom module parameter in case
-	some applications were relying on it. Changing regulatory domains
-	can now be done instead by using nl80211, as is done with iw.

+What:	fakephp and associated sysfs files in /sys/bus/pci/slots/
+When:	2011
+Why:	In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to
+	represent a machine's physical PCI slots. The change in semantics
+	had userspace implications, as the hotplug core no longer allowed
+	drivers to create multiple sysfs files per physical slot (required
+	for multi-function devices, e.g.). fakephp was seen as a developer's
+	tool only, and its interface changed. Too late, we learned that
+	there were some users of the fakephp interface.
+
+	In 2.6.30, the original fakephp interface was restored. At the same
+	time, the PCI core gained the ability that fakephp provided, namely
+	function-level hot-remove and hot-add.
+
+	Since the PCI core now provides the same functionality, exposed in:
+
+		/sys/bus/pci/rescan
+		/sys/bus/pci/devices/.../remove
+		/sys/bus/pci/devices/.../rescan
+
+	there is no functional reason to maintain fakephp as well.
+
+	We will keep the existing module so that 'modprobe fakephp' will
+	present the old /sys/bus/pci/slots/... interface for compatibility,
+	but users are urged to migrate their applications to the API above.
+
+	After a reasonable transition period, we will remove the legacy
+	fakephp interface.

-dquot-nr and dquot-max
-----------------------
-
-The file dquot-max shows the maximum number of cached disk quota entries.
-
-The file  dquot-nr  shows  the  number of allocated disk quota entries and the
-number of free disk quota entries.
-
-If the number of available cached disk quotas is very low and you have a large
-number of simultaneous system users, you might want to raise the limit.
-
-file-nr and file-max
---------------------
-
-The kernel  allocates file handles dynamically, but doesn't free them again at
-this time.
-
-The value  in  file-max  denotes  the  maximum number of file handles that the
-Linux kernel will allocate. When you get a lot of error messages about running
-out of  file handles, you might want to raise this limit. The default value is
-10% of  RAM in kilobytes.  To  change it, just  write the new number  into the
-file:
-
-  # cat /proc/sys/fs/file-max 
-  4096 
-  # echo 8192 > /proc/sys/fs/file-max 
-  # cat /proc/sys/fs/file-max 
-  8192 
-
-
-This method  of  revision  is  useful  for  all customizable parameters of the
-kernel - simply echo the new value to the corresponding file.
-
-Historically, the three values in file-nr denoted the number of allocated file
-handles,  the number of  allocated but  unused file  handles, and  the maximum
-number of file handles. Linux 2.6 always  reports 0 as the number of free file
-handles -- this  is not an error,  it just means that the  number of allocated
-file handles exactly matches the number of used file handles.
-
-Attempts to  allocate more  file descriptors than  file-max are  reported with
-printk, look for "VFS: file-max limit <number> reached".
-
-inode-state and inode-nr
-------------------------
-
-The file inode-nr contains the first two items from inode-state, so we'll skip
-to that file...
-
-inode-state contains  two  actual numbers and five dummy values. The numbers
-are nr_inodes and nr_free_inodes (in order of appearance).
-
-nr_inodes
-~~~~~~~~~
-
-Denotes the  number  of  inodes the system has allocated. This number will
-grow and shrink dynamically.
-
-nr_open
--------
-
-Denotes the maximum number of file-handles a process can
-allocate. Default value is 1024*1024 (1048576) which should be
-enough for most machines. Actual limit depends on RLIMIT_NOFILE
-resource limit.
-
-nr_free_inodes
---------------
-
-Represents the  number of free inodes. Ie. The number of inuse inodes is
-(nr_inodes - nr_free_inodes).
-
-aio-nr and aio-max-nr
----------------------
-
-aio-nr is the running total of the number of events specified on the
-io_setup system call for all currently active aio contexts.  If aio-nr
-reaches aio-max-nr then io_setup will fail with EAGAIN.  Note that
-raising aio-max-nr does not result in the pre-allocation or re-sizing
-of any kernel data structures.
-
-2.2 /proc/sys/fs/binfmt_misc - Miscellaneous binary formats
------------------------------------------------------------
-
-Besides these  files, there is the subdirectory /proc/sys/fs/binfmt_misc. This
-handles the kernel support for miscellaneous binary formats.
-
-Binfmt_misc provides  the ability to register additional binary formats to the
-Kernel without  compiling  an additional module/kernel. Therefore, binfmt_misc
-needs to  know magic numbers at the beginning or the filename extension of the
-binary.
-
-It works by maintaining a linked list of structs that contain a description of
-a binary  format,  including  a  magic  with size (or the filename extension),
-offset and  mask,  and  the  interpreter name. On request it invokes the given
-interpreter with  the  original  program  as  argument,  as  binfmt_java  and
-binfmt_em86 and  binfmt_mz  do.  Since binfmt_misc does not define any default
-binary-formats, you have to register an additional binary-format.
-
-There are two general files in binfmt_misc and one file per registered format.
-The two general files are register and status.
-
-Registering a new binary format
--------------------------------
-
-To register a new binary format you have to issue the command
-
-  echo :name:type:offset:magic:mask:interpreter: > /proc/sys/fs/binfmt_misc/register 
-
-
-
-with appropriate  name (the name for the /proc-dir entry), offset (defaults to
-0, if  omitted),  magic, mask (which can be omitted, defaults to all 0xff) and
-last but  not  least,  the  interpreter that is to be invoked (for example and
-testing /bin/echo).  Type  can be M for usual magic matching or E for filename
-extension matching (give extension in place of magic).
-
-Check or reset the status of the binary format handler
-------------------------------------------------------
-
-If you  do a cat on the file /proc/sys/fs/binfmt_misc/status, you will get the
-current status (enabled/disabled) of binfmt_misc. Change the status by echoing
-0 (disables)  or  1  (enables)  or  -1  (caution:  this  clears all previously
-registered binary  formats)  to status. For example echo 0 > status to disable
-binfmt_misc (temporarily).
-
-Status of a single handler
---------------------------
-
-Each registered  handler has an entry in /proc/sys/fs/binfmt_misc. These files
-perform the  same function as status, but their scope is limited to the actual
-binary format.  By  cating this file, you also receive all related information
-about the interpreter/magic of the binfmt.
-
-Example usage of binfmt_misc (emulate binfmt_java)
---------------------------------------------------
-
-  cd /proc/sys/fs/binfmt_misc  
-  echo ':Java:M::\xca\xfe\xba\xbe::/usr/local/java/bin/javawrapper:' > register  
-  echo ':HTML:E::html::/usr/local/java/bin/appletviewer:' > register  
-  echo ':Applet:M::<!--applet::/usr/local/java/bin/appletviewer:' > register 
-  echo ':DEXE:M::\x0eDEX::/usr/bin/dosexec:' > register 
-
-
-These four  lines  add  support  for  Java  executables and Java applets (like
-binfmt_java, additionally  recognizing the .html extension with no need to put
-<!--applet> to  every  applet  file).  You  have  to  install  the JDK and the
-shell-script /usr/local/java/bin/javawrapper  too.  It  works  around  the
-brokenness of  the Java filename handling. To add a Java binary, just create a
-link to the class-file somewhere in the path.
-
-2.3 /proc/sys/kernel - general kernel parameters
-------------------------------------------------
-
-This directory  reflects  general  kernel  behaviors. As I've said before, the
-contents depend  on  your  configuration.  Here you'll find the most important
-files, along with descriptions of what they mean and how to use them.
-
-acct
-----
-
-The file contains three values; highwater, lowwater, and frequency.
-
-It exists  only  when  BSD-style  process  accounting is enabled. These values
-control its behavior. If the free space on the file system where the log lives
-goes below  lowwater  percentage,  accounting  suspends.  If  it  goes  above
-highwater percentage,  accounting  resumes. Frequency determines how often you
-check the amount of free space (value is in seconds). Default settings are: 4,
-2, and  30.  That is, suspend accounting if there is less than 2 percent free;
-resume it  if we have a value of 3 or more percent; consider information about
-the amount of free space valid for 30 seconds
-
-ctrl-alt-del
-------------
-
-When the value in this file is 0, ctrl-alt-del is trapped and sent to the init
-program to  handle a graceful restart. However, when the value is greater that
-zero, Linux's  reaction  to  this key combination will be an immediate reboot,
-without syncing its dirty buffers.
-
-[NOTE]
-    When a  program  (like  dosemu)  has  the  keyboard  in  raw  mode,  the
-    ctrl-alt-del is  intercepted  by  the  program  before it ever reaches the
-    kernel tty  layer,  and  it is up to the program to decide what to do with
-    it.
-
-domainname and hostname
------------------------
-
-These files  can  be controlled to set the NIS domainname and hostname of your
-box. For the classic darkstar.frop.org a simple:
-
-  # echo "darkstar" > /proc/sys/kernel/hostname 
-  # echo "frop.org" > /proc/sys/kernel/domainname 
-
-
-would suffice to set your hostname and NIS domainname.
-
-osrelease, ostype and version
------------------------------
-
-The names make it pretty obvious what these fields contain:
-
-  > cat /proc/sys/kernel/osrelease 
-  2.2.12 
-   
-  > cat /proc/sys/kernel/ostype 
-  Linux 
-   
-  > cat /proc/sys/kernel/version 
-  #4 Fri Oct 1 12:41:14 PDT 1999 
-
-
-The files  osrelease and ostype should be clear enough. Version needs a little
-more clarification.  The  #4 means that this is the 4th kernel built from this
-source base and the date after it indicates the time the kernel was built. The
-only way to tune these values is to rebuild the kernel.
-
-panic
------
-
-The value  in  this  file  represents  the  number of seconds the kernel waits
-before rebooting  on  a  panic.  When  you  use  the  software  watchdog,  the
-recommended setting  is  60. If set to 0, the auto reboot after a kernel panic
-is disabled, which is the default setting.
-
-printk
-------
-
-The four values in printk denote
-* console_loglevel,
-* default_message_loglevel,
-* minimum_console_loglevel and
-* default_console_loglevel
-respectively.
-
-These values  influence  printk()  behavior  when  printing  or  logging error
-messages, which  come  from  inside  the  kernel.  See  syslog(2)  for  more
-information on the different log levels.
-
-console_loglevel
-----------------
-
-Messages with a higher priority than this will be printed to the console.
-
-default_message_level
----------------------
-
-Messages without an explicit priority will be printed with this priority.
-
-minimum_console_loglevel
-------------------------
-
-Minimum (highest) value to which the console_loglevel can be set.
-
-default_console_loglevel
-------------------------
-
-Default value for console_loglevel.
-
-sg-big-buff
------------
-
-This file  shows  the size of the generic SCSI (sg) buffer. At this point, you
-can't tune  it  yet,  but  you  can  change  it  at  compile  time  by editing
-include/scsi/sg.h and changing the value of SG_BIG_BUFF.
-
-If you use a scanner with SANE (Scanner Access Now Easy) you might want to set
-this to a higher value. Refer to the SANE documentation on this issue.
-
-modprobe
---------
-
-The location  where  the  modprobe  binary  is  located.  The kernel uses this
-program to load modules on demand.
-
-unknown_nmi_panic
------------------
-
-The value in this file affects behavior of handling NMI. When the value is
-non-zero, unknown NMI is trapped and then panic occurs. At that time, kernel
-debugging information is displayed on console.
-
-NMI switch that most IA32 servers have fires unknown NMI up, for example.
-If a system hangs up, try pressing the NMI switch.
-
-panic_on_unrecovered_nmi
-------------------------
-
-The default Linux behaviour on an NMI of either memory or unknown is to continue
-operation. For many environments such as scientific computing it is preferable
-that the box is taken out and the error dealt with than an uncorrected
-parity/ECC error get propogated.
-
-A small number of systems do generate NMI's for bizarre random reasons such as
-power management so the default is off. That sysctl works like the existing
-panic controls already in that directory.
-
-nmi_watchdog
-------------
-
-Enables/Disables the NMI watchdog on x86 systems.  When the value is non-zero
-the NMI watchdog is enabled and will continuously test all online cpus to
-determine whether or not they are still functioning properly. Currently,
-passing "nmi_watchdog=" parameter at boot time is required for this function
-to work.
-
-If LAPIC NMI watchdog method is in use (nmi_watchdog=2 kernel parameter), the
-NMI watchdog shares registers with oprofile. By disabling the NMI watchdog,
-oprofile may have more registers to utilize.
-
-msgmni
-------
-
-Maximum number of message queue ids on the system.
-This value scales to the amount of lowmem. It is automatically recomputed
-upon memory add/remove or ipc namespace creation/removal.
-When a value is written into this file, msgmni's value becomes fixed, i.e. it
-is not recomputed anymore when one of the above events occurs.
-Use auto_msgmni to change this behavior.
-
-auto_msgmni
------------
-
-Enables/Disables automatic recomputing of msgmni upon memory add/remove or
-upon ipc namespace creation/removal (see the msgmni description above).
-Echoing "1" into this file enables msgmni automatic recomputing.
-Echoing "0" turns it off.
-auto_msgmni default value is 1.
-
-
-2.4 /proc/sys/vm - The virtual memory subsystem
------------------------------------------------
-
-Please see: Documentation/sysctls/vm.txt for a description of these
+Please see: Documentation/sysctls/ directory for descriptions of these
 entries.
 
+------------------------------------------------------------------------------
+Summary
+------------------------------------------------------------------------------
+Certain aspects  of  kernel  behavior  can be modified at runtime, without the
+need to  recompile  the kernel, or even to reboot the system. The files in the
+/proc/sys tree  can  not only be read, but also modified. You can use the echo
+command to write value into these files, thereby changing the default settings
+of the kernel.
+------------------------------------------------------------------------------
 
-2.5 /proc/sys/dev - Device specific parameters
-----------------------------------------------
-
-Currently there is only support for CDROM drives, and for those, there is only
-one read-only  file containing information about the CD-ROM drives attached to
-the system:
-
-  >cat /proc/sys/dev/cdrom/info 
-  CD-ROM information, Id: cdrom.c 2.55 1999/04/25 
-   
-  drive name:             sr0     hdb 
-  drive speed:            32      40 
-  drive # of slots:       1       0 
-  Can close tray:         1       1 
-  Can open tray:          1       1 
-  Can lock tray:          1       1 
-  Can change speed:       1       1 
-  Can select disk:        0       1 
-  Can read multisession:  1       1 
-  Can read MCN:           1       1 
-  Reports media changed:  1       1 
-  Can play audio:         1       1 
-
-
-You see two drives, sr0 and hdb, along with a list of their features.
-
-2.6 /proc/sys/sunrpc - Remote procedure calls
----------------------------------------------
-
-This directory  contains four files, which enable or disable debugging for the
-RPC functions NFS, NFS-daemon, RPC and NLM. The default values are 0. They can
-be set to one to turn debugging on. (The default value is 0 for each)
-
-2.7 /proc/sys/net - Networking stuff
-------------------------------------
-
-The interface  to  the  networking  parts  of  the  kernel  is  located  in
-/proc/sys/net. Table  2-3  shows all possible subdirectories. You may see only
-some of them, depending on your kernel's configuration.
-
-
-Table 2-3: Subdirectories in /proc/sys/net 
-..............................................................................
- Directory Content             Directory  Content            
- core      General parameter   appletalk  Appletalk protocol 
- unix      Unix domain sockets netrom     NET/ROM            
- 802       E802 protocol       ax25       AX25               
- ethernet  Ethernet protocol   rose       X.25 PLP layer     
- ipv4      IP version 4        x25        X.25 protocol      
- ipx       IPX                 token-ring IBM token ring     
- bridge    Bridging            decnet     DEC net            
- ipv6      IP version 6                   
-..............................................................................
-
-We will  concentrate  on IP networking here. Since AX15, X.25, and DEC Net are
-only minor players in the Linux world, we'll skip them in this chapter. You'll
-find some  short  info on Appletalk and IPX further on in this chapter. Review
-the online  documentation  and the kernel source to get a detailed view of the
-parameters for  those  protocols.  In  this  section  we'll  discuss  the
-subdirectories printed  in  bold letters in the table above. As default values
-are suitable for most needs, there is no need to change these values.
-
-/proc/sys/net/core - Network core options
------------------------------------------
-
-rmem_default
-------------
-
-The default setting of the socket receive buffer in bytes.
-
-rmem_max
---------
-
-The maximum receive socket buffer size in bytes.
-
-wmem_default
-------------
-
-The default setting (in bytes) of the socket send buffer.
-
-wmem_max
---------
-
-The maximum send socket buffer size in bytes.
-
-message_burst and message_cost
-------------------------------
-
-These parameters  are used to limit the warning messages written to the kernel
-log from  the  networking  code.  They  enforce  a  rate  limit  to  make  a
-denial-of-service attack  impossible. A higher message_cost factor, results in
-fewer messages that will be written. Message_burst controls when messages will
-be dropped.  The  default  settings  limit  warning messages to one every five
-seconds.
-
-warnings
---------
-
-This controls console messages from the networking stack that can occur because
-of problems on the network like duplicate address or bad checksums. Normally,
-this should be enabled, but if the problem persists the messages can be
-disabled.
-
-netdev_budget
--------------
-
-Maximum number of packets taken from all interfaces in one polling cycle (NAPI
-poll). In one polling cycle interfaces which are registered to polling are
-probed in a round-robin manner. The limit of packets in one such probe can be
-set per-device via sysfs class/net/<device>/weight .
-
-netdev_max_backlog
-------------------
-
-Maximum number  of  packets,  queued  on  the  INPUT  side, when the interface
-receives packets faster than kernel can process them.
-
-optmem_max
-----------
-
-Maximum ancillary buffer size allowed per socket. Ancillary data is a sequence
-of struct cmsghdr structures with appended data.
-
-/proc/sys/net/unix - Parameters for Unix domain sockets
--------------------------------------------------------
-
-There are  only  two  files  in this subdirectory. They control the delays for
-deleting and destroying socket descriptors.
-
-2.8 /proc/sys/net/ipv4 - IPV4 settings
---------------------------------------
-
-IP version  4  is  still the most used protocol in Unix networking. It will be
-replaced by  IP version 6 in the next couple of years, but for the moment it's
-the de  facto  standard  for  the  internet  and  is  used  in most networking
-environments around  the  world.  Because  of the importance of this protocol,
-we'll have a deeper look into the subtree controlling the behavior of the IPv4
-subsystem of the Linux kernel.
-
-Let's start with the entries in /proc/sys/net/ipv4.
-
-ICMP settings
--------------
-
-icmp_echo_ignore_all and icmp_echo_ignore_broadcasts
-----------------------------------------------------
-
-Turn on (1) or off (0), if the kernel should ignore all ICMP ECHO requests, or
-just those to broadcast and multicast addresses.
-
-Please note that if you accept ICMP echo requests with a broadcast/multi\-cast
-destination address  your  network  may  be  used as an exploder for denial of
-service packet flooding attacks to other hosts.
-
-icmp_destunreach_rate, icmp_echoreply_rate, icmp_paramprob_rate and icmp_timeexeed_rate
----------------------------------------------------------------------------------------
-
-Sets limits  for  sending  ICMP  packets  to specific targets. A value of zero
-disables all  limiting.  Any  positive  value sets the maximum package rate in
-hundredth of a second (on Intel systems).
-
-IP settings
------------
-
-ip_autoconfig
--------------
-
-This file contains the number one if the host received its IP configuration by
-RARP, BOOTP, DHCP or a similar mechanism. Otherwise it is zero.
-
-ip_default_ttl
---------------
-
-TTL (Time  To  Live) for IPv4 interfaces. This is simply the maximum number of
-hops a packet may travel.
-
-ip_dynaddr
-----------
-
-Enable dynamic  socket  address rewriting on interface address change. This is
-useful for dialup interface with changing IP addresses.
-
-ip_forward
-----------
-
-Enable or  disable forwarding of IP packages between interfaces. Changing this
-value resets  all other parameters to their default values. They differ if the
-kernel is configured as host or router.
-
-ip_local_port_range
--------------------
-
-Range of  ports  used  by  TCP  and UDP to choose the local port. Contains two
-numbers, the  first  number  is the lowest port, the second number the highest
-local port.  Default  is  1024-4999.  Should  be  changed  to  32768-61000 for
-high-usage systems.
-
-ip_no_pmtu_disc
----------------
-
-Global switch  to  turn  path  MTU  discovery off. It can also be set on a per
-socket basis by the applications or on a per route basis.
-
-ip_masq_debug
--------------
-
-Enable/disable debugging of IP masquerading.
-
-IP fragmentation settings
--------------------------
-
-ipfrag_high_trash and ipfrag_low_trash
---------------------------------------
-
-Maximum memory  used to reassemble IP fragments. When ipfrag_high_thresh bytes
-of memory  is  allocated  for  this  purpose,  the  fragment handler will toss
-packets until ipfrag_low_thresh is reached.
-
-ipfrag_time
------------
-
-Time in seconds to keep an IP fragment in memory.
-
-TCP settings
-------------
-
-tcp_ecn
--------
-
-This file controls the use of the ECN bit in the IPv4 headers. This is a new
-feature about Explicit Congestion Notification, but some routers and firewalls
-block traffic that has this bit set, so it could be necessary to echo 0 to
-/proc/sys/net/ipv4/tcp_ecn if you want to talk to these sites. For more info
-you could read RFC2481.
-
-tcp_retrans_collapse
---------------------
-
-Bug-to-bug compatibility with some broken printers. On retransmit, try to send
-larger packets to work around bugs in certain TCP stacks. Can be turned off by
-setting it to zero.
-
-tcp_keepalive_probes
---------------------
-
-Number of  keep  alive  probes  TCP  sends  out,  until  it  decides  that the
-connection is broken.
-
-tcp_keepalive_time
-------------------
-
-How often  TCP  sends out keep alive messages, when keep alive is enabled. The
-default is 2 hours.
-
-tcp_syn_retries
----------------
-
-Number of  times  initial  SYNs  for  a  TCP  connection  attempt  will  be
-retransmitted. Should  not  be  higher  than 255. This is only the timeout for
-outgoing connections,  for  incoming  connections the number of retransmits is
-defined by tcp_retries1.
-
-tcp_sack
---------
-
-Enable select acknowledgments after RFC2018.
-
-tcp_timestamps
---------------
-
-Enable timestamps as defined in RFC1323.
-
-tcp_stdurg
-----------
-
-Enable the  strict  RFC793 interpretation of the TCP urgent pointer field. The
-default is  to  use  the  BSD  compatible interpretation of the urgent pointer
-pointing to the first byte after the urgent data. The RFC793 interpretation is
-to have  it  point  to  the last byte of urgent data. Enabling this option may
-lead to interoperability problems. Disabled by default.
-
-tcp_syncookies
---------------
-
-Only valid  when  the  kernel  was  compiled  with CONFIG_SYNCOOKIES. Send out
-syncookies when  the  syn backlog queue of a socket overflows. This is to ward
-off the common 'syn flood attack'. Disabled by default.
-
-Note that  the  concept  of a socket backlog is abandoned. This means the peer
-may not  receive  reliable  error  messages  from  an  over loaded server with
-syncookies enabled.
-
-tcp_window_scaling
-------------------
-
-Enable window scaling as defined in RFC1323.
-
-tcp_fin_timeout
----------------
-
-The length  of  time  in  seconds  it  takes to receive a final FIN before the
-socket is  always  closed.  This  is  strictly  a  violation  of  the  TCP
-specification, but required to prevent denial-of-service attacks.
-
-tcp_max_ka_probes
------------------
-
-Indicates how  many  keep alive probes are sent per slow timer run. Should not
-be set too high to prevent bursts.
-
-tcp_max_syn_backlog
--------------------
-
-Length of  the per socket backlog queue. Since Linux 2.2 the backlog specified
-in listen(2)  only  specifies  the  length  of  the  backlog  queue of already
-established sockets. When more connection requests arrive Linux starts to drop
-packets. When  syncookies  are  enabled the packets are still answered and the
-maximum queue is effectively ignored.
-
-tcp_retries1
-------------
-
-Defines how  often  an  answer  to  a  TCP connection request is retransmitted
-before giving up.
-
-tcp_retries2
-------------
-
-Defines how often a TCP packet is retransmitted before giving up.
-
-Interface specific settings
----------------------------
-
-In the directory /proc/sys/net/ipv4/conf you'll find one subdirectory for each
-interface the  system  knows about and one directory calls all. Changes in the
-all subdirectory  affect  all  interfaces,  whereas  changes  in  the  other
-subdirectories affect  only  one  interface.  All  directories  have  the same
-entries:
-
-accept_redirects
-----------------
-
-This switch  decides  if the kernel accepts ICMP redirect messages or not. The
-default is 'yes' if the kernel is configured for a regular host and 'no' for a
-router configuration.
-
-accept_source_route
--------------------
-
-Should source  routed  packages  be  accepted  or  declined.  The  default  is
-dependent on  the  kernel  configuration.  It's 'yes' for routers and 'no' for
-hosts.
-
-bootp_relay
-~~~~~~~~~~~
-
-Accept packets  with source address 0.b.c.d with destinations not to this host
-as local ones. It is supposed that a BOOTP relay daemon will catch and forward
-such packets.
-
-The default  is  0,  since this feature is not implemented yet (kernel version
-2.2.12).
-
-forwarding
-----------
-
-Enable or disable IP forwarding on this interface.
-
-log_martians
-------------
-
-Log packets with source addresses with no known route to kernel log.
-
-mc_forwarding
--------------
-
-Do multicast routing. The kernel needs to be compiled with CONFIG_MROUTE and a
-multicast routing daemon is required.
-
-proxy_arp
----------
-
-Does (1) or does not (0) perform proxy ARP.
-
-rp_filter
----------
-
-Integer value determines if a source validation should be made. 1 means yes, 0
-means no.  Disabled by default, but local/broadcast address spoofing is always
-on.
-
-If you  set this to 1 on a router that is the only connection for a network to
-the net,  it  will  prevent  spoofing  attacks  against your internal networks
-(external addresses  can  still  be  spoofed), without the need for additional
-firewall rules.
-
-secure_redirects
-----------------
-
-Accept ICMP  redirect  messages  only  for gateways, listed in default gateway
-list. Enabled by default.
-
-shared_media
-------------
-
-If it  is  not  set  the kernel does not assume that different subnets on this
-device can communicate directly. Default setting is 'yes'.
-
-send_redirects
---------------
-
-Determines whether to send ICMP redirects to other hosts.
-
-Routing settings
-----------------
-
-The directory  /proc/sys/net/ipv4/route  contains  several  file  to  control
-routing issues.
-
-error_burst and error_cost
---------------------------
-
-These  parameters  are used to limit how many ICMP destination unreachable to 
-send  from  the  host  in question. ICMP destination unreachable messages are 
-sent  when  we  cannot reach  the next hop while trying to transmit a packet. 
-It  will also print some error messages to kernel logs if someone is ignoring 
-our   ICMP  redirects.  The  higher  the  error_cost  factor  is,  the  fewer 
-destination  unreachable  and error messages will be let through. Error_burst 
-controls  when  destination  unreachable  messages and error messages will be
-dropped. The default settings limit warning messages to five every second.
-
-flush
------
-
-Writing to this file results in a flush of the routing cache.
-
-gc_elasticity, gc_interval, gc_min_interval_ms, gc_timeout, gc_thresh
----------------------------------------------------------------------
-
-Values to  control  the  frequency  and  behavior  of  the  garbage collection
-algorithm for the routing cache. gc_min_interval is deprecated and replaced
-by gc_min_interval_ms.
-
-
-max_size
---------
-
-Maximum size  of  the routing cache. Old entries will be purged once the cache
-reached has this size.
-
-redirect_load, redirect_number
-------------------------------
-
-Factors which  determine  if  more ICPM redirects should be sent to a specific
-host. No  redirects  will be sent once the load limit or the maximum number of
-redirects has been reached.
-
-redirect_silence
-----------------
-
-Timeout for redirects. After this period redirects will be sent again, even if
-this has been stopped, because the load or number limit has been reached.
-
-Network Neighbor handling
--------------------------
-
-Settings about how to handle connections with direct neighbors (nodes attached
-to the same link) can be found in the directory /proc/sys/net/ipv4/neigh.
-
-As we  saw  it  in  the  conf directory, there is a default subdirectory which
-holds the  default  values, and one directory for each interface. The contents
-of the  directories  are identical, with the single exception that the default
-settings contain additional options to set garbage collection parameters.
-
-In the interface directories you'll find the following entries:
-
-base_reachable_time, base_reachable_time_ms
--------------------------------------------
-
-A base  value  used for computing the random reachable time value as specified
-in RFC2461.
-
-Expression of base_reachable_time, which is deprecated, is in seconds.
-Expression of base_reachable_time_ms is in milliseconds.
-
-retrans_time, retrans_time_ms
------------------------------
-
-The time between retransmitted Neighbor Solicitation messages.
-Used for address resolution and to determine if a neighbor is
-unreachable.
-
-Expression of retrans_time, which is deprecated, is in 1/100 seconds (for
-IPv4) or in jiffies (for IPv6).
-Expression of retrans_time_ms is in milliseconds.
-
-unres_qlen
-----------
-
-Maximum queue  length  for a pending arp request - the number of packets which
-are accepted from other layers while the ARP address is still resolved.
-
-anycast_delay
--------------
-
-Maximum for  random  delay  of  answers  to  neighbor solicitation messages in
-jiffies (1/100  sec). Not yet implemented (Linux does not have anycast support
-yet).
-
-ucast_solicit
--------------
-
-Maximum number of retries for unicast solicitation.
-
-mcast_solicit
--------------
-
-Maximum number of retries for multicast solicitation.
-
-delay_first_probe_time
-----------------------
-
-Delay for  the  first  time  probe  if  the  neighbor  is  reachable.  (see
-gc_stale_time)
-
-locktime
---------
-
-An ARP/neighbor  entry  is only replaced with a new one if the old is at least
-locktime old. This prevents ARP cache thrashing.
-
-proxy_delay
------------
-
-Maximum time  (real  time is random [0..proxytime]) before answering to an ARP
-request for  which  we have an proxy ARP entry. In some cases, this is used to
-prevent network flooding.
-
-proxy_qlen
-----------
-
-Maximum queue length of the delayed proxy arp timer. (see proxy_delay).
-
-app_solicit
-----------
-
-Determines the  number of requests to send to the user level ARP daemon. Use 0
-to turn off.
-
-gc_stale_time
--------------
-
-Determines how  often  to  check  for stale ARP entries. After an ARP entry is
-stale it  will  be resolved again (which is useful when an IP address migrates
-to another  machine).  When  ucast_solicit is greater than 0 it first tries to
-send an  ARP  packet  directly  to  the  known  host  When  that  fails  and
-mcast_solicit is greater than 0, an ARP request is broadcasted.
-
-2.9 Appletalk
--------------
-
-The /proc/sys/net/appletalk  directory  holds the Appletalk configuration data
-when Appletalk is loaded. The configurable parameters are:
-
-aarp-expiry-time
-----------------
-
-The amount  of  time  we keep an ARP entry before expiring it. Used to age out
-old hosts.
-
-aarp-resolve-time
------------------
-
-The amount of time we will spend trying to resolve an Appletalk address.
-
-aarp-retransmit-limit
----------------------
-
-The number of times we will retransmit a query before giving up.
-
-aarp-tick-time
---------------
-
-Controls the rate at which expires are checked.
-
-The directory  /proc/net/appletalk  holds the list of active Appletalk sockets
-on a machine.
-
-The fields  indicate  the DDP type, the local address (in network:node format)
-the remote  address,  the  size of the transmit pending queue, the size of the
-received queue  (bytes waiting for applications to read) the state and the uid
-owning the socket.
-
-/proc/net/atalk_iface lists  all  the  interfaces  configured for appletalk.It
-shows the  name  of the interface, its Appletalk address, the network range on
-that address  (or  network number for phase 1 networks), and the status of the
-interface.
-
-/proc/net/atalk_route lists  each  known  network  route.  It lists the target
-(network) that the route leads to, the router (may be directly connected), the
-route flags, and the device the route is using.
-
-2.10 IPX
---------
-
-The IPX protocol has no tunable values in proc/sys/net.
-
-The IPX  protocol  does,  however,  provide  proc/net/ipx. This lists each IPX
-socket giving  the  local  and  remote  addresses  in  Novell  format (that is
-network:node:port). In  accordance  with  the  strange  Novell  tradition,
-everything but the port is in hex. Not_Connected is displayed for sockets that
-are not  tied to a specific remote address. The Tx and Rx queue sizes indicate
-the number  of  bytes  pending  for  transmission  and  reception.  The  state
-indicates the  state  the  socket  is  in and the uid is the owning uid of the
-socket.
-
-The /proc/net/ipx_interface  file lists all IPX interfaces. For each interface
-it gives  the network number, the node number, and indicates if the network is
-the primary  network.  It  also  indicates  which  device  it  is bound to (or
-Internal for  internal  networks)  and  the  Frame  Type if appropriate. Linux
-supports 802.3,  802.2,  802.2  SNAP  and DIX (Blue Book) ethernet framing for
-IPX.
-
-The /proc/net/ipx_route  table  holds  a list of IPX routes. For each route it
-gives the  destination  network, the router node (or Directly) and the network
-address of the router (or Connected) for internal networks.
-
-2.11 /proc/sys/fs/mqueue - POSIX message queues filesystem
-----------------------------------------------------------
-
-The "mqueue"  filesystem provides  the necessary kernel features to enable the
-creation of a  user space  library that  implements  the  POSIX message queues
-API (as noted by the  MSG tag in the  POSIX 1003.1-2001 version  of the System
-Interfaces specification.)
-
-The "mqueue" filesystem contains values for determining/setting  the amount of
-resources used by the file system.
-
-/proc/sys/fs/mqueue/queues_max is a read/write  file for  setting/getting  the
-maximum number of message queues allowed on the system.
-
-/proc/sys/fs/mqueue/msg_max  is  a  read/write file  for  setting/getting  the
-maximum number of messages in a queue value.  In fact it is the limiting value
-for another (user) limit which is set in mq_open invocation. This attribute of
-a queue must be less or equal then msg_max.
-
-/proc/sys/fs/mqueue/msgsize_max is  a read/write  file for setting/getting the
-maximum  message size value (it is every  message queue's attribute set during
-its creation).

-(the driver manages them):

-Note that this is what the DONE bit in the DS1621 configuration register is
-good for: Internally, one temperature conversion takes up to 1000ms. Before
-that conversion is complete you will not be able to read valid things out
-of REG_COUNT and REG_SLOPE. The DONE bit, as you may have guessed by now,
-tells you whether the conversion is complete ("done", in plain English) and
-thus, whether the values you read are good or not.
-
-The DS1621 has two modes of operation: "Continuous" conversion, which can
-be understood as the default stand-alone mode where the chip gets the
-temperature and controls external devices via its Tout pin or tells other
-i2c's about it if they care. The other mode is called "1SHOT", that means
-that it only figures out about the temperature when it is explicitly told
-to do so; this can be seen as power saving mode.
-
-Now if you want to read REG_COUNT and REG_SLOPE, you have to either stop
-the continuous conversions until the contents of these registers are valid,
-or, in 1SHOT mode, you have to have one conversion made.

+How to instantiate I2C devices
+==============================
+
+Unlike PCI or USB devices, I2C devices are not enumerated at the hardware
+level. Instead, the software must know which devices are connected on each
+I2C bus segment, and what address these devices are using. For this
+reason, the kernel code must instantiate I2C devices explicitly. There are
+several ways to achieve this, depending on the context and requirements.
+
+
+Method 1: Declare the I2C devices by bus number
+-----------------------------------------------
+
+This method is appropriate when the I2C bus is a system bus as is the case
+for many embedded systems. On such systems, each I2C bus has a number
+which is known in advance. It is thus possible to pre-declare the I2C
+devices which live on this bus. This is done with an array of struct
+i2c_board_info which is registered by calling i2c_register_board_info().
+
+Example (from omap2 h4):
+
+static struct i2c_board_info __initdata h4_i2c_board_info[] = {
+	{
+		I2C_BOARD_INFO("isp1301_omap", 0x2d),
+		.irq		= OMAP_GPIO_IRQ(125),
+	},
+	{	/* EEPROM on mainboard */
+		I2C_BOARD_INFO("24c01", 0x52),
+		.platform_data	= &m24c01,
+	},
+	{	/* EEPROM on cpu card */
+		I2C_BOARD_INFO("24c01", 0x57),
+		.platform_data	= &m24c01,
+	},
+};
+
+static void __init omap_h4_init(void)
+{
+	(...)
+	i2c_register_board_info(1, h4_i2c_board_info,
+			ARRAY_SIZE(h4_i2c_board_info));
+	(...)
+}
+
+The above code declares 3 devices on I2C bus 1, including their respective
+addresses and custom data needed by their drivers. When the I2C bus in
+question is registered, the I2C devices will be instantiated automatically
+by i2c-core.
+
+The devices will be automatically unbound and destroyed when the I2C bus
+they sit on goes away (if ever.)
+
+
+Method 2: Instantiate the devices explicitly
+--------------------------------------------
+
+This method is appropriate when a larger device uses an I2C bus for
+internal communication. A typical case is TV adapters. These can have a
+tuner, a video decoder, an audio decoder, etc. usually connected to the
+main chip by the means of an I2C bus. You won't know the number of the I2C
+bus in advance, so the method 1 described above can't be used. Instead,
+you can instantiate your I2C devices explicitly. This is done by filling
+a struct i2c_board_info and calling i2c_new_device().
+
+Example (from the sfe4001 network driver):
+
+static struct i2c_board_info sfe4001_hwmon_info = {
+	I2C_BOARD_INFO("max6647", 0x4e),
+};
+
+int sfe4001_init(struct efx_nic *efx)
+{
+	(...)
+	efx->board_info.hwmon_client =
+		i2c_new_device(&efx->i2c_adap, &sfe4001_hwmon_info);
+
+	(...)
+}
+
+The above code instantiates 1 I2C device on the I2C bus which is on the
+network adapter in question.
+
+A variant of this is when you don't know for sure if an I2C device is
+present or not (for example for an optional feature which is not present
+on cheap variants of a board but you have no way to tell them apart), or
+it may have different addresses from one board to the next (manufacturer
+changing its design without notice). In this case, you can call
+i2c_new_probed_device() instead of i2c_new_device().
+
+Example (from the pnx4008 OHCI driver):
+
+static const unsigned short normal_i2c[] = { 0x2c, 0x2d, I2C_CLIENT_END };
+
+static int __devinit usb_hcd_pnx4008_probe(struct platform_device *pdev)
+{
+	(...)
+	struct i2c_adapter *i2c_adap;
+	struct i2c_board_info i2c_info;
+
+	(...)
+	i2c_adap = i2c_get_adapter(2);
+	memset(&i2c_info, 0, sizeof(struct i2c_board_info));
+	strlcpy(i2c_info.name, "isp1301_pnx", I2C_NAME_SIZE);
+	isp1301_i2c_client = i2c_new_probed_device(i2c_adap, &i2c_info,
+						   normal_i2c);
+	i2c_put_adapter(i2c_adap);
+	(...)
+}
+
+The above code instantiates up to 1 I2C device on the I2C bus which is on
+the OHCI adapter in question. It first tries at address 0x2c, if nothing
+is found there it tries address 0x2d, and if still nothing is found, it
+simply gives up.
+
+The driver which instantiated the I2C device is responsible for destroying
+it on cleanup. This is done by calling i2c_unregister_device() on the
+pointer that was earlier returned by i2c_new_device() or
+i2c_new_probed_device().
+
+
+Method 3: Probe an I2C bus for certain devices
+----------------------------------------------
+
+Sometimes you do not have enough information about an I2C device, not even
+to call i2c_new_probed_device(). The typical case is hardware monitoring
+chips on PC mainboards. There are several dozen models, which can live
+at 25 different addresses. Given the huge number of mainboards out there,
+it is next to impossible to build an exhaustive list of the hardware
+monitoring chips being used. Fortunately, most of these chips have
+manufacturer and device ID registers, so they can be identified by
+probing.
+
+In that case, I2C devices are neither declared nor instantiated
+explicitly. Instead, i2c-core will probe for such devices as soon as their
+drivers are loaded, and if any is found, an I2C device will be
+instantiated automatically. In order to prevent any misbehavior of this
+mechanism, the following restrictions apply:
+* The I2C device driver must implement the detect() method, which
+  identifies a supported device by reading from arbitrary registers.
+* Only buses which are likely to have a supported device and agree to be
+  probed, will be probed. For example this avoids probing for hardware
+  monitoring chips on a TV adapter.
+
+Example:
+See lm90_driver and lm90_detect() in drivers/hwmon/lm90.c
+
+I2C devices instantiated as a result of such a successful probe will be
+destroyed automatically when the driver which detected them is removed,
+or when the underlying I2C bus is itself destroyed, whichever happens
+first.
+
+Those of you familiar with the i2c subsystem of 2.4 kernels and early 2.6
+kernels will find out that this method 3 is essentially similar to what
+was done there. Two significant differences are:
+* Probing is only one way to instantiate I2C devices now, while it was the
+  only way back then. Where possible, methods 1 and 2 should be preferred.
+  Method 3 should only be used when there is no other way, as it can have
+  undesirable side effects.
+* I2C buses must now explicitly say which I2C driver classes can probe
+  them (by the means of the class bitfield), while all I2C buses were
+  probed by default back then. The default is an empty class which means
+  that no probing happens. The purpose of the class bitfield is to limit
+  the aforementioned undesirable side effects.
+
+Once again, method 3 should be avoided wherever possible. Explicit device
+instantiation (methods 1 and 2) is much preferred for it is safer and
+faster.

+Kernel driver isl29003
+=====================
+
+Supported chips:
+* Intersil ISL29003
+Prefix: 'isl29003'
+Addresses scanned: none
+Datasheet:
+http://www.intersil.com/data/fn/fn7464.pdf
+
+Author: Daniel Mack <daniel@caiaq.de>
+
+
+Description
+-----------
+The ISL29003 is an integrated light sensor with a 16-bit integrating type
+ADC, I2C user programmable lux range select for optimized counts/lux, and
+I2C multi-function control and monitoring capabilities. The internal ADC
+provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by
+artificial light sources.
+
+The driver allows to set the lux range, the bit resolution, the operational
+mode (see below) and the power state of device and can read the current lux
+value, of course.
+
+
+Detection
+---------
+
+The ISL29003 does not have an ID register which could be used to identify
+it, so the detection routine will just try to read from the configured I2C
+addess and consider the device to be present as soon as it ACKs the
+transfer.

+Neterion's (Formerly S2io) X3100 Series 10GbE PCIe Server Adapter Linux driver
+==============================================================================
+
+Contents
+--------
+
+1) Introduction
+2) Features supported
+3) Configurable driver parameters
+4) Troubleshooting
+
+1) Introduction:
+----------------
+This Linux driver supports all Neterion's X3100 series 10 GbE PCIe I/O
+Virtualized Server adapters.
+The X3100 series supports four modes of operation, configurable via
+firmware -
+	Single function mode
+	Multi function mode
+	SRIOV mode
+	MRIOV mode
+The functions share a 10GbE link and the pci-e bus, but hardly anything else
+inside the ASIC. Features like independent hw reset, statistics, bandwidth/
+priority allocation and guarantees, GRO, TSO, interrupt moderation etc are
+supported independently on each function.
+
+(See below for a complete list of features supported for both IPv4 and IPv6)
+
+2) Features supported:
+----------------------
+
+i)   Single function mode (up to 17 queues)
+
+ii)  Multi function mode (up to 17 functions)
+
+iii) PCI-SIG's I/O Virtualization
+       - Single Root mode: v1.0 (up to 17 functions)
+       - Multi-Root mode: v1.0 (up to 17 functions)
+
+iv)  Jumbo frames
+       X3100 Series supports MTU up to 9600 bytes, modifiable using
+       ifconfig command.
+
+v)   Offloads supported: (Enabled by default)
+       Checksum offload (TCP/UDP/IP) on transmit and receive paths
+       TCP Segmentation Offload (TSO) on transmit path
+       Generic Receive Offload (GRO) on receive path
+
+vi)  MSI-X: (Enabled by default)
+       Resulting in noticeable performance improvement (up to 7% on certain
+       platforms).
+
+vii) NAPI: (Enabled by default)
+       For better Rx interrupt moderation.
+
+viii)RTH (Receive Traffic Hash): (Enabled by default)
+       Receive side steering for better scaling.
+
+ix)  Statistics
+       Comprehensive MAC-level and software statistics displayed using
+       "ethtool -S" option.
+
+x)   Multiple hardware queues: (Enabled by default)
+       Up to 17 hardware based transmit and receive data channels, with
+       multiple steering options (transmit multiqueue enabled by default).
+
+3) Configurable driver parameters:
+----------------------------------
+
+i)  max_config_dev
+       Specifies maximum device functions to be enabled.
+       Valid range: 1-8
+
+ii) max_config_port
+       Specifies number of ports to be enabled.
+       Valid range: 1,2
+       Default: 1
+
+iii)max_config_vpath
+       Specifies maximum VPATH(s) configured for each device function.
+       Valid range: 1-17
+
+iv) vlan_tag_strip
+       Enables/disables vlan tag stripping from all received tagged frames that
+       are not replicated at the internal L2 switch.
+       Valid range: 0,1 (disabled, enabled respectively)
+       Default: 1
+
+v)  addr_learn_en
+       Enable learning the mac address of the guest OS interface in
+       virtualization environment.
+       Valid range: 0,1 (disabled, enabled respectively)
+       Default: 0
+
+4) Troubleshooting:
+-------------------
+
+To resolve an issue with the source code or X3100 series adapter, please collect
+the statistics, register dumps using ethool, relevant logs and email them to
+support@neterion.com.

+The OSD Standard
+================
+OSD (Object-Based Storage Device) is a T10 SCSI command set that is designed
+to provide efficient operation of input/output logical units that manage the
+allocation, placement, and accessing of variable-size data-storage containers,
+called objects. Objects are intended to contain operating system and application
+constructs. Each object has associated attributes attached to it, which are
+integral part of the object and provide metadata about the object. The standard
+defines some common obligatory attributes, but user attributes can be added as
+needed.
+
+See: http://www.t10.org/ftp/t10/drafts/osd2/ for the latest draft for OSD 2
+or search the web for "OSD SCSI"

+  The main component of OSD in Kernel is the osd-initiator library. Its main
+user is intended to be the pNFS-over-objects layout driver, which uses objects
+as its back-end data storage. Other clients are the other osd parts listed below.
+
+osd-uld:
+  This is a SCSI ULD that registers for OSD type devices and provides a testing
+platform, both for the in-kernel initiator as well as connected targets. It
+currently has no useful user-mode API, though it could have if need be.
+
+exofs:
+  Is an OSD based Linux file system. It uses the osd-initiator and osd-uld,
+to export a usable file system for users.
+See Documentation/filesystems/exofs.txt for more details
+
+osd target:
+  There are no current plans for an OSD target implementation in kernel. For all
+needs, a user-mode target that is based on the scsi tgt target framework is
+available from Ohio Supercomputer Center (OSC) at:
+http://www.open-osd.org/bin/view/Main/OscOsdProject
+There are several other target implementations. See http://open-osd.org for more
+links.

+The OSD-Initiator Library
+=========================
+osd_initiator is a low level implementation of an osd initiator encoder.
+But even though, it should be intuitive and easy to use. Perhaps over time an
+higher lever will form that automates some of the more common recipes.
+
+init/fini:
+- osd_dev_init() associates a scsi_device with an osd_dev structure
+  and initializes some global pools. This should be done once per scsi_device
+  (OSD LUN). The osd_dev structure is needed for calling osd_start_request().
+
+- osd_dev_fini() cleans up before a osd_dev/scsi_device destruction.
+
+OSD commands encoding, execution, and decoding of results:
+
+struct osd_request's is used to iteratively encode an OSD command and carry
+its state throughout execution. Each request goes through these stages:
+
+a. osd_start_request() allocates the request.
+
+b. Any of the osd_req_* methods is used to encode a request of the specified
+   type.
+
+c. osd_req_add_{get,set}_attr_* may be called to add get/set attributes to the
+   CDB. "List" or "Page" mode can be used exclusively. The attribute-list API
+   can be called multiple times on the same request. However, only one
+   attribute-page can be read, as mandated by the OSD standard.
+
+d. osd_finalize_request() computes offsets into the data-in and data-out buffers
+   and signs the request using the provided capability key and integrity-
+   check parameters.
+
+e. osd_execute_request() may be called to execute the request via the block
+   layer and wait for its completion.  The request can be executed
+   asynchronously by calling the block layer API directly.
+
+f. After execution, osd_req_decode_sense() can be called to decode the request's
+   sense information.
+
+g. osd_req_decode_get_attr() may be called to retrieve osd_add_get_attr_list()
+   values.
+
+h. osd_end_request() must be called to deallocate the request and any resource
+   associated with it. Note that osd_end_request cleans up the request at any
+   stage and it must always be called after a successful osd_start_request().
+
+osd_request's structure:
+
+The OSD standard defines a complex structure of IO segments pointed to by
+members in the CDB. Up to 3 segments can be deployed in the IN-Buffer and up to
+4 in the OUT-Buffer. The ASCII illustration below depicts a secure-read with
+associated get+set of attributes-lists. Other combinations very on the same
+basic theme. From no-segments-used up to all-segments-used.

+
+A block device request can carry bidirectional payload by means of associating
+a bidi_read request with a main write-request. Each in/out request is described
+by a chain of BIOs associated with each request.
+The CDB is of a SCSI VARLEN CDB format, as described by OSD standard.
+The OSD standard also mandates alignment restrictions at start of each segment.
+
+In the code, in struct osd_request, there are two _osd_io_info structures to
+describe the IN/OUT buffers above, two BIOs for the data payload and up to five
+_osd_req_data_segment structures to hold the different segments allocation and
+information.
+
+Important: We have chosen to disregard the assumption that a BIO-chain (and
+the resulting sg-list) describes a linear memory buffer. Meaning only first and
+last scatter chain can be incomplete and all the middle chains are of PAGE_SIZE.
+For us, a scatter-gather-list, as its name implies and as used by the Networking
+layer, is to describe a vector of buffers that will be transferred to/from the
+wire. It works very well with current iSCSI transport. iSCSI is currently the
+only deployed OSD transport. In the future we anticipate SAS and FC attached OSD
+devices as well.

+----------------------------------------------------------
+
+The "mqueue"  filesystem provides  the necessary kernel features to enable the

+API (as noted by the  MSG tag in the  POSIX 1003.1-2001 version  of the System
+Interfaces specification.)

+4. /proc/sys/fs/epoll - Configuration options for the epoll interface
+--------------------------------------------------------
+
+This directory contains configuration options for the epoll(7) interface.
+
+max_user_instances
+------------------
+
+This is the maximum number of epoll file descriptors that a single user can
+have open at a given time. The default value is 128, and should be enough
+for normal users.
+
+max_user_watches
+----------------
+
+Every epoll file descriptor can store a number of files to be monitored
+for event readiness. Each one of these monitored files constitutes a "watch".
+This configuration option sets the maximum number of "watches" that are
+allowed for each user.
+Each "watch" costs roughly 90 bytes on a 32bit kernel, and roughly 160 bytes
+on a 64bit one.
+The current default value for  max_user_watches  is the 1/32 of the available
+low memory, divided for the "watch" cost in bytes.

+
+The interface  to  the  networking  parts  of  the  kernel  is  located  in
+/proc/sys/net. The following table shows all possible subdirectories.You may
+see only some of them, depending on your kernel's configuration.

+..............................................................................
+
+1. /proc/sys/net/core - Network core options
+-------------------------------------------------------
+
+rmem_default
+------------
+
+The default setting of the socket receive buffer in bytes.
+
+rmem_max
+--------
+
+The maximum receive socket buffer size in bytes.
+
+wmem_default
+------------
+
+The default setting (in bytes) of the socket send buffer.
+
+wmem_max
+--------
+
+The maximum send socket buffer size in bytes.
+
+message_burst and message_cost
+------------------------------
+
+These parameters  are used to limit the warning messages written to the kernel
+log from  the  networking  code.  They  enforce  a  rate  limit  to  make  a
+denial-of-service attack  impossible. A higher message_cost factor, results in
+fewer messages that will be written. Message_burst controls when messages will
+be dropped.  The  default  settings  limit  warning messages to one every five
+seconds.
+
+warnings
+--------
+
+This controls console messages from the networking stack that can occur because
+of problems on the network like duplicate address or bad checksums. Normally,
+this should be enabled, but if the problem persists the messages can be
+disabled.
+
+netdev_budget
+-------------
+
+Maximum number of packets taken from all interfaces in one polling cycle (NAPI
+poll). In one polling cycle interfaces which are registered to polling are
+probed in a round-robin manner. The limit of packets in one such probe can be
+set per-device via sysfs class/net/<device>/weight .
+
+netdev_max_backlog
+------------------
+
+Maximum number  of  packets,  queued  on  the  INPUT  side, when the interface
+receives packets faster than kernel can process them.
+
+optmem_max
+----------
+
+Maximum ancillary buffer size allowed per socket. Ancillary data is a sequence
+of struct cmsghdr structures with appended data.
+
+2. /proc/sys/net/unix - Parameters for Unix domain sockets
+-------------------------------------------------------
+
+There is only one file in this directory.
+unix_dgram_qlen limits the max number of datagrams queued in Unix domain
+socket's buffer. It will not take effect unless PF_UNIX flag is spicified.
+
+
+3. /proc/sys/net/ipv4 - IPV4 settings
+-------------------------------------------------------
+Please see: Documentation/networking/ip-sysctl.txt and ipvs-sysctl.txt for
+descriptions of these entries.
+
+
+4. Appletalk
+-------------------------------------------------------
+
+The /proc/sys/net/appletalk  directory  holds the Appletalk configuration data
+when Appletalk is loaded. The configurable parameters are:
+
+aarp-expiry-time
+----------------
+
+The amount  of  time  we keep an ARP entry before expiring it. Used to age out
+old hosts.
+
+aarp-resolve-time
+-----------------
+
+The amount of time we will spend trying to resolve an Appletalk address.
+
+aarp-retransmit-limit
+---------------------
+
+The number of times we will retransmit a query before giving up.
+
+aarp-tick-time
+--------------
+
+Controls the rate at which expires are checked.
+
+The directory  /proc/net/appletalk  holds the list of active Appletalk sockets
+on a machine.
+
+The fields  indicate  the DDP type, the local address (in network:node format)
+the remote  address,  the  size of the transmit pending queue, the size of the
+received queue  (bytes waiting for applications to read) the state and the uid
+owning the socket.
+
+/proc/net/atalk_iface lists  all  the  interfaces  configured for appletalk.It
+shows the  name  of the interface, its Appletalk address, the network range on
+that address  (or  network number for phase 1 networks), and the status of the
+interface.
+
+/proc/net/atalk_route lists  each  known  network  route.  It lists the target
+(network) that the route leads to, the router (may be directly connected), the
+route flags, and the device the route is using.
+
+
+5. IPX
+-------------------------------------------------------
+
+The IPX protocol has no tunable values in proc/sys/net.
+
+The IPX  protocol  does,  however,  provide  proc/net/ipx. This lists each IPX
+socket giving  the  local  and  remote  addresses  in  Novell  format (that is
+network:node:port). In  accordance  with  the  strange  Novell  tradition,
+everything but the port is in hex. Not_Connected is displayed for sockets that
+are not  tied to a specific remote address. The Tx and Rx queue sizes indicate
+the number  of  bytes  pending  for  transmission  and  reception.  The  state
+indicates the  state  the  socket  is  in and the uid is the owning uid of the
+socket.
+
+The /proc/net/ipx_interface  file lists all IPX interfaces. For each interface
+it gives  the network number, the node number, and indicates if the network is
+the primary  network.  It  also  indicates  which  device  it  is bound to (or
+Internal for  internal  networks)  and  the  Frame  Type if appropriate. Linux
+supports 802.3,  802.2,  802.2  SNAP  and DIX (Blue Book) ethernet framing for
+IPX.
+
+The /proc/net/ipx_route  table  holds  a list of IPX routes. For each route it
+gives the  destination  network, the router node (or Directly) and the network
+address of the router (or Connected) for internal networks.

+
+video buffer helper functions
+-----------------------------
+
+The v4l2 core API provides a standard method for dealing with video
+buffers. Those methods allow a driver to implement read(), mmap() and
+overlay() on a consistent way.
+
+There are currently methods for using video buffers on devices that
+supports DMA with scatter/gather method (videobuf-dma-sg), DMA with
+linear access (videobuf-dma-contig), and vmalloced buffers, mostly
+used on USB drivers (videobuf-vmalloc).
+
+Any driver using videobuf should provide operations (callbacks) for
+four handlers:
+
+ops->buf_setup   - calculates the size of the video buffers and avoid they
+		   to waste more than some maximum limit of RAM;
+ops->buf_prepare - fills the video buffer structs and calls
+		   videobuf_iolock() to alloc and prepare mmaped memory;
+ops->buf_queue   - advices the driver that another buffer were
+		   requested (by read() or by QBUF);
+ops->buf_release - frees any buffer that were allocated.
+
+In order to use it, the driver need to have a code (generally called at
+interrupt context) that will properly handle the buffer request lists,
+announcing that a new buffer were filled.
+
+The irq handling code should handle the videobuf task lists, in order
+to advice videobuf that a new frame were filled, in order to honor to a
+request. The code is generally like this one:
+	if (list_empty(&dma_q->active))
+		return;
+
+	buf = list_entry(dma_q->active.next, struct vbuffer, vb.queue);
+
+	if (!waitqueue_active(&buf->vb.done))
+		return;
+
+	/* Some logic to handle the buf may be needed here */
+
+	list_del(&buf->vb.queue);
+	do_gettimeofday(&buf->vb.ts);
+	wake_up(&buf->vb.done);
+
+Those are the videobuffer functions used on drivers, implemented on
+videobuf-core:
+
+- Videobuf init functions
+  videobuf_queue_sg_init()
+      Initializes the videobuf infrastructure. This function should be
+      called before any other videobuf function on drivers that uses DMA
+      Scatter/Gather buffers.
+
+  videobuf_queue_dma_contig_init
+      Initializes the videobuf infrastructure. This function should be
+      called before any other videobuf function on drivers that need DMA
+      contiguous buffers.
+
+  videobuf_queue_vmalloc_init()
+      Initializes the videobuf infrastructure. This function should be
+      called before any other videobuf function on USB (and other drivers)
+      that need a vmalloced type of videobuf.
+
+- videobuf_iolock()
+  Prepares the videobuf memory for the proper method (read, mmap, overlay).
+
+- videobuf_queue_is_busy()
+  Checks if a videobuf is streaming.
+
+- videobuf_queue_cancel()
+  Stops video handling.
+
+- videobuf_mmap_free()
+  frees mmap buffers.
+
+- videobuf_stop()
+  Stops video handling, ends mmap and frees mmap and other buffers.
+
+- V4L2 api functions. Those functions correspond to VIDIOC_foo ioctls:
+   videobuf_reqbufs(), videobuf_querybuf(), videobuf_qbuf(),
+   videobuf_dqbuf(), videobuf_streamon(), videobuf_streamoff().
+
+- V4L1 api function (corresponds to VIDIOCMBUF ioctl):
+   videobuf_cgmbuf()
+      This function is used to provide backward compatibility with V4L1
+      API.
+
+- Some help functions for read()/poll() operations:
+   videobuf_read_stream()
+      For continuous stream read()
+   videobuf_read_one()
+      For snapshot read()
+   videobuf_poll_stream()
+      polling help function
+
+The better way to understand it is to take a look at vivi driver. One
+of the main reasons for vivi is to be a videobuf usage example. the
+vivi_thread_tick() does the task that the IRQ callback would do on PCI
+drivers (or the irq callback on USB).

+ ...
+
+( If your system does not list a debug port capability then you probably
+  wont be able to use the USB debug key. )
+
+ b.) You also need a Netchip USB debug cable/key:
+
+        http://www.plxtech.com/products/NET2000/NET20DC/default.asp
+
+     This is a small blue plastic connector with two USB connections,
+     it draws power from its USB connections.
+
+ c.) Thirdly, you need a second client/console system with a regular USB port.
+
+2. Software requirements:
+
+ a.) On the host/target system:
+
+    You need to enable the following kernel config option:
+
+      CONFIG_EARLY_PRINTK_DBGP=y
+
+    And you need to add the boot command line: "earlyprintk=dbgp".
+    (If you are using Grub, append it to the 'kernel' line in
+     /etc/grub.conf)
+
+    NOTE: normally earlyprintk console gets turned off once the
+    regular console is alive - use "earlyprintk=dbgp,keep" to keep
+    this channel open beyond early bootup. This can be useful for
+    debugging crashes under Xorg, etc.
+
+ b.) On the client/console system:
+
+    You should enable the following kernel config option:
+
+      CONFIG_USB_SERIAL_DEBUG=y
+
+    On the next bootup with the modified kernel you should
+    get a /dev/ttyUSBx device(s).
+
+    Now this channel of kernel messages is ready to be used: start
+    your favorite terminal emulator (minicom, etc.) and set
+    it up to use /dev/ttyUSB0 - or use a raw 'cat /dev/ttyUSBx' to
+    see the raw output.
+
+ c.) On Nvidia Southbridge based systems: the kernel will try to probe
+     and find out which port has debug device connected.
+
+3. Testing that it works fine:
+
+   You can test the output by using earlyprintk=dbgp,keep and provoking
+   kernel messages on the host/target system. You can provoke a harmless
+   kernel message by for example doing:
+
+     echo h > /proc/sysrq-trigger
+
+   On the host/target system you should see this help line in "dmesg" output:
+
+     SysRq : HELP : loglevel(0-9) reBoot Crashdump terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) saK show-backtrace-all-active-cpus(L) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) unRaw Sync show-task-states(T) Unmount show-blocked-tasks(W) dump-ftrace-buffer(Z)
+
+   On the client/console system do:
+
+       cat /dev/ttyUSB0
+
+   And you should see the help line above displayed shortly after you've
+   provoked it on the host system.
+
+If it does not work then please ask about it on the linux-kernel@vger.kernel.org
+mailing list or contact the x86 maintainers.

- * Definitions for PPC440
- *
- * Because of the 3 word TLB entries to support 36-bit addressing,
- * the attribute are difficult to map in such a fashion that they
- * are easily loaded during exception processing.  I decided to
- * organize the entry so the ERPN is the only portion in the
- * upper word of the PTE and the attribute bits below are packed
- * in as sensibly as they can be in the area below a 4KB page size
- * oriented RPN.  This at least makes it easy to load the RPN and
- * ERPN fields in the TLB. -Matt
- *
- * Note that these bits preclude future use of a page size
- * less than 4KB.
- *
- *
- * PPC 440 core has following TLB attribute fields;
- *
- *   TLB1:
- *   0  1  2  3  4  ... 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- *   RPN.................................  -  -  -  -  -  - ERPN.......
- *
- *   TLB2:
- *   0  1  2  3  4  ... 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- *   -  -  -  -  -    - U0 U1 U2 U3 W  I  M  G  E   - UX UW UR SX SW SR
- *
- * Newer 440 cores (440x6 as used on AMCC 460EX/460GT) have additional
- * TLB2 storage attibute fields. Those are:
- *
- *   TLB2:
- *   0...10    11   12   13   14   15   16...31
- *   no change WL1  IL1I IL1D IL2I IL2D no change
- *
- * There are some constrains and options, to decide mapping software bits
- * into TLB entry.
- *
- *   - PRESENT *must* be in the bottom three bits because swap cache
- *     entries use the top 29 bits for TLB2.
- *
- *   - FILE *must* be in the bottom three bits because swap cache
- *     entries use the top 29 bits for TLB2.
- *
- *   - CACHE COHERENT bit (M) has no effect on original PPC440 cores,
- *     because it doesn't support SMP. However, some later 460 variants
- *     have -some- form of SMP support and so I keep the bit there for
- *     future use
- *
- * With the PPC 44x Linux implementation, the 0-11th LSBs of the PTE are used
- * for memory protection related functions (see PTE structure in
- * include/asm-ppc/mmu.h).  The _PAGE_XXX definitions in this file map to the
- * above bits.  Note that the bit values are CPU specific, not architecture
- * specific.
- *
- * The kernel PTE entry holds an arch-dependent swp_entry structure under
- * certain situations. In other words, in such situations some portion of
- * the PTE bits are used as a swp_entry. In the PPC implementation, the
- * 3-24th LSB are shared with swp_entry, however the 0-2nd three LSB still
- * hold protection values. That means the three protection bits are
- * reserved for both PTE and SWAP entry at the most significant three
- * LSBs.
- *
- * There are three protection bits available for SWAP entry:
- *	_PAGE_PRESENT
- *	_PAGE_FILE
- *	_PAGE_HASHPTE (if HW has)
- *
- * So those three bits have to be inside of 0-2nd LSB of PTE.

+ * There are several potential gotchas here.  The 40x hardware TLBLO

+ * - We use only zones 0 (for kernel pages) and 1 (for user pages)
+ *   of the 16 available.  Bit 24-26 of the TLB are cleared in the TLB
+ *   miss handler.  Bit 27 is PAGE_USER, thus selecting the correct
+ *   zone.
+ * - PRESENT *must* be in the bottom two bits because swap cache
+ *   entries use the top 30 bits.  Because 40x doesn't support SMP
+ *   anyway, M is irrelevant so we borrow it for PAGE_PRESENT.  Bit 30
+ *   is cleared in the TLB miss handler before the TLB entry is loaded.
+ * - All other bits of the PTE are loaded into TLBLO without
+ *   modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
+ *   software PTE bits.  We actually use use bits 21, 24, 25, and

+ *
+ * Newer 440 cores (440x6 as used on AMCC 460EX/460GT) have additional
+ * TLB2 storage attibute fields. Those are:
+ *
+ *   TLB2:
+ *   0...10    11   12   13   14   15   16...31
+ *   no change WL1  IL1I IL1D IL2I IL2D no change
+ *
+ * There are some constrains and options, to decide mapping software bits
+ * into TLB entry.
+ *
+ *   - PRESENT *must* be in the bottom three bits because swap cache
+ *     entries use the top 29 bits for TLB2.
+ *
+ *   - FILE *must* be in the bottom three bits because swap cache
+ *     entries use the top 29 bits for TLB2.
+ *
+ *   - CACHE COHERENT bit (M) has no effect on original PPC440 cores,
+ *     because it doesn't support SMP. However, some later 460 variants
+ *     have -some- form of SMP support and so I keep the bit there for
+ *     future use
+ *
+ * With the PPC 44x Linux implementation, the 0-11th LSBs of the PTE are used
+ * for memory protection related functions (see PTE structure in
+ * include/asm-ppc/mmu.h).  The _PAGE_XXX definitions in this file map to the
+ * above bits.  Note that the bit values are CPU specific, not architecture
+ * specific.
+ *
+ * The kernel PTE entry holds an arch-dependent swp_entry structure under
+ * certain situations. In other words, in such situations some portion of
+ * the PTE bits are used as a swp_entry. In the PPC implementation, the
+ * 3-24th LSB are shared with swp_entry, however the 0-2nd three LSB still
+ * hold protection values. That means the three protection bits are
+ * reserved for both PTE and SWAP entry at the most significant three
+ * LSBs.
+ *
+ * There are three protection bits available for SWAP entry:

+ *
+ * This file is a driver for the the General Purpose Timer (gpt) devices
+ * found on the MPC5200 SoC.  Each timer has an IO pin which can be used
+ * for GPIO or can be used to raise interrupts.  The timer function can
+ * be used independently from the IO pin, or it can be used to control
+ * output signals or measure input signals.
+ *
+ * This driver supports the GPIO and IRQ controller functions of the GPT
+ * device.  Timer functions are not yet supported, nor is the watchdog
+ * timer.
+ *
+ * To use the GPIO function, the following two properties must be added
+ * to the device tree node for the gpt device (typically in the .dts file
+ * for the board):
+ * 	gpio-controller;
+ * 	#gpio-cells = < 2 >;
+ * This driver will register the GPIO pin if it finds the gpio-controller
+ * property in the device tree.
+ *
+ * To use the IRQ controller function, the following two properties must
+ * be added to the device tree node for the gpt device:
+ * 	interrupt-controller;
+ * 	#interrupt-cells = < 1 >;
+ * The IRQ controller binding only uses one cell to specify the interrupt,
+ * and the IRQ flags are encoded in the cell.  A cell is not used to encode
+ * the IRQ number because the GPT only has a single IRQ source.  For flags,
+ * a value of '1' means rising edge sensitive and '2' means falling edge.
+ *
+ * The GPIO and the IRQ controller functions can be used at the same time,
+ * but in this use case the IO line will only work as an input.  Trying to
+ * use it as a GPIO output will not work.
+ *
+ * When using the GPIO line as an output, it can either be driven as normal
+ * IO, or it can be an Open Collector (OC) output.  At the moment it is the
+ * responsibility of either the bootloader or the platform setup code to set
+ * the output mode.  This driver does not change the output mode setting.

+ [callee-clobbered]   |                    | [callee-clobbered] |

+
+ ( rsp is obviously invariant across normal function calls. (gcc can 'merge'
+   functions when it sees tail-call optimization possibilities) rflags is
+   clobbered. Leftover arguments are passed over the stack frame.)
+
+ [*]  In the frame-pointers case rbp is fixed to the stack frame.
+
+ [**] for struct return values wider than 64 bits the return convention is a
+      bit more complex: up to 128 bits width we return small structures
+      straight in rax, rdx. For structures larger than that (3 words or
+      larger) the caller puts a pointer to an on-stack return struct
+      [allocated in the caller's stack frame] into the first argument - i.e.
+      into rdi. All other arguments shift up by one in this case.
+      Fortunately this case is rare in the kernel.
+
+For 32-bit we have the following conventions - kernel is built with
+-mregparm=3 and -freg-struct-return:

+ ----------------------------------------
+  arguments         | callee-saved        | extra caller-saved | return

+ ( here too esp is obviously invariant across normal function calls. eflags
+   is clobbered. Leftover arguments are passed over the stack frame. )
+
+ [*]  In the frame-pointers case ebp is fixed to the stack frame.
+
+ [**] We build with -freg-struct-return, which on 32-bit means similar
+      semantics as on 64-bit: edx can be used for a second return value
+      (i.e. covering integer and structure sizes up to 64 bits) - after that
+      it gets more complex and more expensive: 3-word or larger struct returns
+      get done in the caller's frame and the pointer to the return struct goes
+      into regparm0, i.e. eax - the other arguments shift up and the
+      function's register parameters degenerate to regparm=2 in essence.

+ * GCC stack protector support.
+ *
+ * Stack protector works by putting predefined pattern at the start of
+ * the stack frame and verifying that it hasn't been overwritten when
+ * returning from the function.  The pattern is called stack canary
+ * and unfortunately gcc requires it to be at a fixed offset from %gs.
+ * On x86_64, the offset is 40 bytes and on x86_32 20 bytes.  x86_64
+ * and x86_32 use segment registers differently and thus handles this
+ * requirement differently.
+ *
+ * On x86_64, %gs is shared by percpu area and stack canary.  All
+ * percpu symbols are zero based and %gs points to the base of percpu
+ * area.  The first occupant of the percpu area is always
+ * irq_stack_union which contains stack_canary at offset 40.  Userland
+ * %gs is always saved and restored on kernel entry and exit using
+ * swapgs, so stack protector doesn't add any complexity there.
+ *
+ * On x86_32, it's slightly more complicated.  As in x86_64, %gs is
+ * used for userland TLS.  Unfortunately, some processors are much
+ * slower at loading segment registers with different value when
+ * entering and leaving the kernel, so the kernel uses %fs for percpu
+ * area and manages %gs lazily so that %gs is switched only when
+ * necessary, usually during task switch.
+ *
+ * As gcc requires the stack canary at %gs:20, %gs can't be managed
+ * lazily if stack protector is enabled, so the kernel saves and
+ * restores userland %gs on kernel entry and exit.  This behavior is
+ * controlled by CONFIG_X86_32_LAZY_GS and accessors are defined in
+ * system.h to hide the details.

+ * This file implements a driver for monitoring and handling events
+ * associated with the IMB DDR2 ECC controller found in the AMCC/IBM
+ * 405EX[r], 440SP, 440SPe, 460EX, 460GT and 460SX.
+ *
+ * As realized in the 405EX[r], this controller features:
+ *
+ *   - Support for registered- and non-registered DDR1 and DDR2 memory.
+ *   - 32-bit or 16-bit memory interface with optional ECC.
+ *
+ *     o ECC support includes:
+ *
+ *       - 4-bit SEC/DED
+ *       - Aligned-nibble error detect
+ *       - Bypass mode
+ *
+ *   - Two (2) memory banks/ranks.
+ *   - Up to 1 GiB per bank/rank in 32-bit mode and up to 512 MiB per
+ *     bank/rank in 16-bit mode.
+ *
+ * As realized in the 440SP and 440SPe, this controller changes/adds:
+ *
+ *   - 64-bit or 32-bit memory interface with optional ECC.
+ *
+ *     o ECC support includes:
+ *
+ *       - 8-bit SEC/DED
+ *       - Aligned-nibble error detect
+ *       - Bypass mode
+ *
+ *   - Up to 4 GiB per bank/rank in 64-bit mode and up to 2 GiB
+ *     per bank/rank in 32-bit mode.
+ *
+ * As realized in the 460EX and 460GT, this controller changes/adds:
+ *
+ *   - 64-bit or 32-bit memory interface with optional ECC.
+ *
+ *     o ECC support includes:
+ *
+ *       - 8-bit SEC/DED
+ *       - Aligned-nibble error detect
+ *       - Bypass mode
+ *
+ *   - Four (4) memory banks/ranks.
+ *   - Up to 16 GiB per bank/rank in 64-bit mode and up to 8 GiB
+ *     per bank/rank in 32-bit mode.
+ *
+ * At present, this driver has ONLY been tested against the controller
+ * realization in the 405EX[r] on the AMCC Kilauea and Haleakala
+ * boards (256 MiB w/o ECC memory soldered onto the board) and a
+ * proprietary board based on those designs (128 MiB ECC memory, also
+ * soldered onto the board).
+ *
+ * Dynamic feature detection and handling needs to be added for the
+ * other realizations of this controller listed above.
+ *
+ * Eventually, this driver will likely be adapted to the above variant
+ * realizations of this controller as well as broken apart to handle
+ * the other known ECC-capable controllers prevalent in other 4xx
+ * processors:
+ *
+ *   - IBM SDRAM (405GP, 405CR and 405EP) "ibm,sdram-4xx"
+ *   - IBM DDR1 (440GP, 440GX, 440EP and 440GR) "ibm,sdram-4xx-ddr"
+ *   - Denali DDR1/DDR2 (440EPX and 440GRX) "denali,sdram-4xx-ddr2"
+ *
+ * For this controller, unfortunately, correctable errors report
+ * nothing more than the beat/cycle and byte/lane the correction
+ * occurred on and the check bit group that covered the error.
+ *
+ * In contrast, uncorrectable errors also report the failing address,

-	  A RAID-5 set can be expanded by adding extra drives. This
-	  requires "restriping" the array which means (almost) every
-	  block must be written to a different place.
-
-          This option allows such restriping to be done while the array
-	  is online.
-
-	  You will need mdadm version 2.4.1 or later to use this
-	  feature safely.  During the early stage of reshape there is
-	  a critical section where live data is being over-written.  A
-	  crash during this time needs extra care for recovery.  The
-	  newer mdadm takes a copy of the data in the critical section
-	  and will restore it, if necessary, after a crash.
-
-	  The mdadm usage is e.g.
-	       mdadm --grow /dev/md1 --raid-disks=6
-	  to grow '/dev/md1' to having 6 disks.
-
-	  Note: The array can only be expanded, not contracted.
-	  There should be enough spares already present to make the new
-	  array workable.

  * 			in usbhid/hid-quirks.c
+ * Version 0.10:	A lot of cleanups and fixes: unpluging the device,
+ * 			few mutex locks were added, codinstyle issues, etc.

  *
  * Many things to do:
  * 	- Correct power managment of device (suspend & resume)
- * 	- Make x86 independance (little-endian and big-endian stuff)
  * 	- Add code for scanning and smooth tuning
- * 	- Checked and add stereo&mono stuff
  * 	- Add code for sensitivity value
  * 	- Correct mistakes
  * 	- In Japan another FREQ_MIN and FREQ_MAX

+ *             buffers until the ownership of the last list in the multi-list
+ *             sequence has been returned to the host.
+ *             Bits 8 to 11 - Reserved
+ *             Bits 12 to 15 - Transfer_Code. This field is only valid in

+ *             For multi-descriptor frames, the only valid gather code sequence
+ *             is {10, [00], 01}. In other words, the descriptors must be placed

+ *             Bits 28 to 29 - LSO_Frm_Encap. LSO Frame Encapsulation

+ * @control_1: Bits 0 to 4 - Reserved.
+ *             Bit 5 - Tx_CKO_IPv4 Set to a '1' to enable IPv4 header checksum

+ *             Bit 6 - Tx_CKO_TCP Set to a '1' to enable TCP checksum offload.
+ *             This field is only valid in the first TxD of a frame (the TxD's
+ *             gather code must be 10 or 11). The driver should only set this
+ *             bit if it can guarantee that TCP is present.
+ *             Bit 7 - Tx_CKO_UDP Set to a '1' to enable UDP checksum offload.
+ *             This field is only valid in the first TxD of a frame (the TxD's

+ *             Bit 46 - Tx_Int_Per_List Set to a '1' to instruct the adapter to
+ *             generate an interrupt as soon as all of the frames in the list
+ *             have been transmitted. In order to have per-frame interrupts,

+ *            total octets of transmitted frames, including framing characters,
+ *            multiply PORTn_TX_TTL_FRMS by 8 and add it to this stat (unless
+ *            otherwise configured, this stat only counts frames that have
+ *            8 bytes of preamble for each frame). This stat can be configured
+ *            (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count everything
+ *            including the preamble octets.
+ * @tx_data_octets: Count of data and padding octets of successfully transmitted
+ *            frames.
+ * @tx_mcast_frms: Count of successfully transmitted frames to a group address
+ *            other than the broadcast address.

+ * @tx_tcp: Count of transmitted TCP segments. Does not include segments
+ *            containing retransmitted octets.
+ * @tx_rst_tcp: Count of transmitted TCP segments containing the RST flag.
+ * @tx_udp: Count of transmitted UDP datagrams.
+ * @tx_parse_error: Increments when the TPA is unable to parse a packet. This
+ *            generally occurs when a packet is corrupt somehow, including
+ *            packets that have IP version mismatches, invalid Layer 2 control
+ *            fields, etc. L3/L4 checksums are not offloaded, but the packet
+ *            is still be transmitted.
+ * @tx_unknown_protocol: Increments when the TPA encounters an unknown
+ *            protocol, such as a new IPv6 extension header, or an unsupported
+ *            Routing Type. The packet still has a checksum calculated but it
+ *            may be incorrect.
+ * @tx_pause_ctrl_frms: Count of MAC PAUSE control frames that are transmitted.
+ *            Since, the only control frames supported by this device are
+ *            PAUSE frames, this register is a count of all transmitted MAC
+ *            control frames.
+ * @tx_marker_pdu_frms: Count of Marker PDUs transmitted

+ * @tx_lacpdu_frms: Count of LACPDUs transmitted on this Aggregation port.
+ * @tx_drop_ip: Count of transmitted IP datagrams that could not be passed to
+ *            the network. Increments because of:
+ *            1) An internal processing error
+ *            (such as an uncorrectable ECC error). 2) A frame parsing error
+ *            during IP checksum calculation.

+ *            is set to /T/ (i.e. the terminate character), thus the statistic
+ *            tracks the number of transmitted Terminate characters.
+ * @tx_xgmii_char1_match: Maintains a count of the number of transmitted XGMII
+ *            characters that match a pattern that is programmable through
+ *            register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern

+ *            to 4 x /E/ (i.e. a column containing all error characters), thus
+ *            the statistic tracks the number of Error columns transmitted at
+ *            any time. If XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is
+ *            set to 1, then this stat increments when COLUMN2 is found within
+ *            'n' clocks after COLUMN1. Here, 'n' is defined by
+ *            XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set
+ *            to 0, then it means to search anywhere for COLUMN2).
+ * @tx_xgmii_column1_match: Maintains a count of the number of transmitted XGMII
+ *            columns that match a pattern that is programmable through register
+ *            XMAC_STATS_TX_XGMII_COLUMN1_PORTn. By default, the pattern is set
+ *            to 4 x /I/ (i.e. a column containing all idle characters),
+ *            thus the statistic tracks the number of transmitted Idle columns.
+ * @tx_any_err_frms: Count of transmitted frames containing any error that
+ *            prevents them from being passed to the network. Increments if
+ *            there is an ECC while reading the frame out of the transmit
+ *            buffer. Also increments if the transmit protocol assist (TPA)
+ *            block determines that the frame should not be sent.
+ * @tx_drop_frms: Count of frames that could not be sent for no other reason
+ *            than internal MAC processing. Increments once whenever the
+ *            transmit buffer is flushed (due to an ECC error on a memory
+ *            descriptor).
+ * @rx_ttl_frms: Count of total received MAC frames, including frames received
+ *            with frame-too-long, FCS, or length errors. This stat can be
+ *            configured (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count
+ *            everything, even "frames" as small one byte of preamble.
+ * @rx_vld_frms: Count of successfully received MAC frames. Does not include
+ *            frames received with frame-too-long, FCS, or length errors.
+ * @rx_offload_frms: Count of offloaded received frames that are passed to
+ *            the host.
+ * @rx_ttl_octets: Count of total octets of received frames, not including
+ *            framing characters (i.e. less framing bits). To determine the
+ *            total octets of received frames, including framing characters,
+ *            multiply PORTn_RX_TTL_FRMS by 8 and add it to this stat (unless
+ *            otherwise configured, this stat only counts frames that have 8
+ *            bytes of preamble for each frame). This stat can be configured
+ *            (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count everything,
+ *            even the preamble octets of "frames" as small one byte of preamble
+ * @rx_data_octets: Count of data and padding octets of successfully received
+ *            frames. Does not include frames received with frame-too-long,
+ *            FCS, or length errors.
+ * @rx_offload_octets: Count of total octets, not including framing
+ *            characters, of offloaded received frames that are passed
+ *            to the host.
+ * @rx_vld_mcast_frms: Count of successfully received MAC frames containing a
+ *	      nonbroadcast group address. Does not include frames received
+ *            with frame-too-long, FCS, or length errors.
+ * @rx_vld_bcast_frms: Count of successfully received MAC frames containing

+ * @rx_accepted_ucast_frms: Count of successfully received frames containing
+ *            a unicast address. Only includes frames that are passed to
+ *            the system.
+ * @rx_accepted_nucast_frms: Count of successfully received frames containing
+ *            a non-unicast (broadcast or multicast) address. Only includes
+ *            frames that are passed to the system. Could include, for instance,
+ *            non-unicast frames that contain FCS errors if the MAC_ERROR_CFG
+ *            register is set to pass FCS-errored frames to the host.
+ * @rx_tagged_frms: Count of received frames containing a VLAN tag.
+ * @rx_long_frms: Count of received frames that are longer than RX_MAX_PYLD_LEN
+ *            + 18 bytes (+ 22 bytes if VLAN-tagged).
+ * @rx_usized_frms: Count of received frames of length (including FCS, but not
+ *            framing bits) less than 64 octets, that are otherwise well-formed.
+ *            In other words, counts runts.
+ * @rx_osized_frms: Count of received frames of length (including FCS, but not
+ *            framing bits) more than 1518 octets, that are otherwise
+ *            well-formed. Note: If register XMAC_STATS_GLOBAL_CFG.VLAN_HANDLING
+ *            is set to 1, then "more than 1518 octets" becomes "more than 1518
+ *            (1522 if VLAN-tagged) octets".
+ * @rx_frag_frms: Count of received frames of length (including FCS, but not
+ *            framing bits) less than 64 octets that had bad FCS. In other

+ * @rx_discarded_frms: Count of received frames containing
+ * 		any error that prevents
+ *            them from being passed to the system. See PORTn_RX_FCS_DISCARD,

+ * @rx_illegal_pdu_frms: Count of received frames (on this Aggregation port)
+ *            that carry the Slow Protocols EtherType, but contain a badly
+ *            formed PDU. Or frames that carry the Slow Protocols EtherType,
+ *            but contain an illegal value of Protocol Subtype.
+ * @rx_switch_discard: Count of received frames that are discarded by the
+ *            internal switch because they did not have an entry in the
+ *            Filtering Database. This includes frames that had an invalid
+ *            destination MAC address or VLAN ID. It also includes frames are
+ *            discarded because they did not satisfy the length requirements
+ *            of the target VPATH.
+ * @rx_len_discard: Count of received frames that are discarded because of an
+ *            invalid frame length (includes fragments, oversized frames and
+ *            mismatch between frame length and length/type field). This stat
+ *            can be configured
+ *            (see XMAC_STATS_GLOBAL_CFG.LEN_DISCARD_HANDLING).
+ * @rx_rpa_discard: Count of received frames that were discarded because the
+ *            receive protocol assist (RPA) discovered and error in the frame
+ *            or was unable to parse the frame.
+ * @rx_l2_mgmt_discard: Count of Layer 2 management frames (eg. pause frames,

+ *            discarded.
+ * @rx_rts_discard: Count of received frames that are discarded by the receive
+ *            traffic steering (RTS) logic. Includes those frame discarded
+ *            because the SSC response contradicted the switch table, because
+ *            the SSC timed out, or because the target queue could not fit the
+ *            frame.
+ * @rx_trash_discard: Count of received frames that are discarded because
+ *            receive traffic steering (RTS) steered the frame to the trash
+ *            queue.
+ * @rx_buff_full_discard: Count of received frames that are discarded because
+ *            internal buffers are full. Includes frames discarded because the
+ *            RTS logic is waiting for an SSC lookup that has no timeout bound.
+ *            Also, includes frames that are dropped because the MAC2FAU buffer
+ *            is nearly full -- this can happen if the external receive buffer
+ *            is full and the receive path is backing up.
+ * @rx_red_discard: Count of received frames that are discarded because of RED
+ *            (Random Early Discard).
+ * @rx_xgmii_ctrl_err_cnt: Maintains a count of unexpected or misplaced control
+ *            characters occuring between times of normal data transmission
+ *            (i.e. not included in RX_XGMII_DATA_ERR_CNT). This counter is
+ *            incremented when either -
+ *            1) The Reconciliation Sublayer (RS) is expecting one control
+ *               character and gets another (i.e. is expecting a Start
+ *               character, but gets another control character).
+ *            2) Start control character is not in lane 0
+ *            Only increments the count by one for each XGMII column.
+ * @rx_xgmii_data_err_cnt: Maintains a count of unexpected control characters
+ *            during normal data transmission. If the Reconciliation Sublayer
+ *            (RS) receives a control character, other than a terminate control
+ *            character, during receipt of data octets then this register is
+ *            incremented. Also increments if the start frame delimiter is not
+ *            found in the correct location. Only increments the count by one
+ *            for each XGMII column.
+ * @rx_xgmii_char1_match: Maintains a count of the number of XGMII characters
+ *            that match a pattern that is programmable through register
+ *            XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
+ *            to /E/ (i.e. the error character), thus the statistic tracks the
+ *            number of Error characters received at any time.
+ * @rx_xgmii_err_sym: Count of the number of symbol errors in the received
+ *            XGMII data (i.e. PHY indicates "Receive Error" on the XGMII).
+ *            Only includes symbol errors that are observed between the XGMII
+ *            Start Frame Delimiter and End Frame Delimiter, inclusive. And
+ *            only increments the count by one for each frame.
+ * @rx_xgmii_column1_match: Maintains a count of the number of XGMII columns
+ *            that match a pattern that is programmable through register
+ *            XMAC_STATS_RX_XGMII_COLUMN1_PORTn. By default, the pattern is set
+ *            to 4 x /E/ (i.e. a column containing all error characters), thus
+ *            the statistic tracks the number of Error columns received at any
+ *            time.
+ * @rx_xgmii_char2_match: Maintains a count of the number of XGMII characters
+ *            that match a pattern that is programmable through register
+ *            XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
+ *            to /E/ (i.e. the error character), thus the statistic tracks the
+ *            number of Error characters received at any time.
+ * @rx_local_fault: Maintains a count of the number of times that link
+ *            transitioned from "up" to "down" due to a local fault.
+ * @rx_xgmii_column2_match: Maintains a count of the number of XGMII columns
+ *            that match a pattern that is programmable through register
+ *            XMAC_STATS_RX_XGMII_COLUMN2_PORTn. By default, the pattern is set
+ *            to 4 x /E/ (i.e. a column containing all error characters), thus
+ *            the statistic tracks the number of Error columns received at any
+ *            time. If XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is set
+ *            to 1, then this stat increments when COLUMN2 is found within 'n'
+ *            clocks after COLUMN1. Here, 'n' is defined by
+ *            XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set to
+ *            0, then it means to search anywhere for COLUMN2).
+ * @rx_jettison: Count of received frames that are jettisoned because internal
+ *            buffers are full.
+ * @rx_remote_fault: Maintains a count of the number of times that link
+ *            transitioned from "up" to "down" due to a remote fault.

+config QUOTA
+	bool "Quota support"
+	help
+	  If you say Y here, you will be able to set per user limits for disk
+	  usage (also called disk quotas). Currently, it works for the
+	  ext2, ext3, and reiserfs file system. ext3 also supports journalled
+	  quotas for which you don't need to run quotacheck(8) after an unclean
+	  shutdown.
+	  For further details, read the Quota mini-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, or the documentation provided
+	  with the quota tools. Probably the quota support is only useful for
+	  multi user systems. If unsure, say N.
+
+config QUOTA_NETLINK_INTERFACE
+	bool "Report quota messages through netlink interface"
+	depends on QUOTA && NET
+	help
+	  If you say Y here, quota warnings (about exceeding softlimit, reaching

+	  say Y.

 It would be easier to read balance_leaf() if each of these summary
 lines was a separate procedure rather than being inlined.  I think
 that there are many passages here and in balance_leaf_when_delete() in
 which two calls to one procedure can replace two passages, and it
-might save cache space and improve software maintenance costs to do so.

+ * linux/mm/percpu.c - percpu memory allocator
+ *
+ * Copyright (C) 2009		SUSE Linux Products GmbH
+ * Copyright (C) 2009		Tejun Heo <tj@kernel.org>
+ *
+ * This file is released under the GPLv2.
+ *
+ * This is percpu allocator which can handle both static and dynamic
+ * areas.  Percpu areas are allocated in chunks in vmalloc area.  Each
+ * chunk is consisted of num_possible_cpus() units and the first chunk
+ * is used for static percpu variables in the kernel image (special
+ * boot time alloc/init handling necessary as these areas need to be
+ * brought up before allocation services are running).  Unit grows as
+ * necessary and all units grow or shrink in unison.  When a chunk is
+ * filled up, another chunk is allocated.  ie. in vmalloc area
+ *
+ *  c0                           c1                         c2
+ *  -------------------          -------------------        ------------
+ * | u0 | u1 | u2 | u3 |        | u0 | u1 | u2 | u3 |      | u0 | u1 | u
+ *  -------------------  ......  -------------------  ....  ------------
+ *
+ * Allocation is done in offset-size areas of single unit space.  Ie,
+ * an area of 512 bytes at 6k in c1 occupies 512 bytes at 6k of c1:u0,
+ * c1:u1, c1:u2 and c1:u3.  Percpu access can be done by configuring
+ * percpu base registers UNIT_SIZE apart.
+ *
+ * There are usually many small percpu allocations many of them as
+ * small as 4 bytes.  The allocator organizes chunks into lists
+ * according to free size and tries to allocate from the fullest one.
+ * Each chunk keeps the maximum contiguous area size hint which is
+ * guaranteed to be eqaul to or larger than the maximum contiguous
+ * area in the chunk.  This helps the allocator not to iterate the
+ * chunk maps unnecessarily.
+ *
+ * Allocation state in each chunk is kept using an array of integers
+ * on chunk->map.  A positive value in the map represents a free
+ * region and negative allocated.  Allocation inside a chunk is done
+ * by scanning this map sequentially and serving the first matching
+ * entry.  This is mostly copied from the percpu_modalloc() allocator.
+ * Chunks are also linked into a rb tree to ease address to chunk
+ * mapping during free.
+ *
+ * To use this allocator, arch code should do the followings.
+ *
+ * - define CONFIG_HAVE_DYNAMIC_PER_CPU_AREA
+ *
+ * - define __addr_to_pcpu_ptr() and __pcpu_ptr_to_addr() to translate
+ *   regular address to percpu pointer and back if they need to be
+ *   different from the default
+ *
+ * - use pcpu_setup_first_chunk() during percpu area initialization to
+ *   setup the first chunk containing the kernel static percpu area
