+Description:
+                Various files for managing Cable Based Association of
+                (wireless) USB devices.
+
+                The sequence of operations should be:
+
+                1. Device is plugged in.
+
+                2. The connection manager (CM) sees a device with CBA capability.
+                   (the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
+
+                3. The CM writes the host name, supported band groups,
+                   and the CHID (host ID) into the wusb_host_name,
+                   wusb_host_band_groups and wusb_chid files. These
+                   get sent to the device and the CDID (if any) for
+                   this host is requested.
+
+                4. The CM can verify that the device's supported band
+                   groups (wusb_device_band_groups) are compatible
+                   with the host.
+
+                5. The CM reads the wusb_cdid file.
+
+                6. The CM looks it up its database.
+
+                   - If it has a matching CHID,CDID entry, the device
+                     has been authorized before and nothing further
+                     needs to be done.
+
+                   - If the CDID is zero (or the CM doesn't find a
+                     matching CDID in its database), the device is
+                     assumed to be not known.  The CM may associate
+                     the host with device by: writing a randomly
+                     generated CDID to wusb_cdid and then a random CK
+                     to wusb_ck (this uploads the new CC to the
+                     device).
+
+                     CMD may choose to prompt the user before
+                     associating with a new device.
+
+                7. Device is unplugged.

-Revision 7, 2007-04-19
-Jean Delvare <khali@linux-fr.org>

-
-This is a guide on how to convert I2C chip drivers from Linux 2.4 to
-Linux 2.6. I have been using existing drivers (lm75, lm78) as examples.
-Then I converted a driver myself (lm83) and updated this document.
-Note that this guide is strongly oriented towards hardware monitoring
-drivers. Many points are still valid for other type of drivers, but
-others may be irrelevant.
-
-There are two sets of points below. The first set concerns technical
-changes. The second set concerns coding policy. Both are mandatory.
-
-Although reading this guide will help you porting drivers, I suggest
-you keep an eye on an already ported driver while porting your own
-driver. This will help you a lot understanding what this guide
-exactly means. Choose the chip driver that is the more similar to
-yours for best results.
-
-Technical changes:
-
-* [Driver type] Any driver that was relying on i2c-isa has to be
-  converted to a proper isa, platform or pci driver. This is not
-  covered by this guide.
-
-* [Includes] Get rid of "version.h" and <linux/i2c-proc.h>.
-  Includes typically look like that:
-  #include <linux/module.h>
-  #include <linux/init.h>
-  #include <linux/slab.h>
-  #include <linux/jiffies.h>
-  #include <linux/i2c.h>
-  #include <linux/hwmon.h>	/* for hardware monitoring drivers */
-  #include <linux/hwmon-sysfs.h>
-  #include <linux/hwmon-vid.h>	/* if you need VRM support */
-  #include <linux/err.h>	/* for class registration */
-  Please respect this inclusion order. Some extra headers may be
-  required for a given driver (e.g. "lm75.h").
-
-* [Addresses] SENSORS_I2C_END becomes I2C_CLIENT_END, ISA addresses
-  are no more handled by the i2c core. Address ranges are no more
-  supported either, define each individual address separately.
-  SENSORS_INSMOD_<n> becomes I2C_CLIENT_INSMOD_<n>.
-
-* [Client data] Get rid of sysctl_id. Try using standard names for
-  register values (for example, temp_os becomes temp_max). You're
-  still relatively free here, but you *have* to follow the standard
-  names for sysfs files (see the Sysctl section below).
-
-* [Function prototypes] The detect functions loses its flags
-  parameter. Sysctl (e.g. lm75_temp) and miscellaneous functions
-  are off the list of prototypes. This usually leaves five
-  prototypes:
-  static int lm75_attach_adapter(struct i2c_adapter *adapter);
-  static int lm75_detect(struct i2c_adapter *adapter, int address,
-      int kind);
-  static void lm75_init_client(struct i2c_client *client);
-  static int lm75_detach_client(struct i2c_client *client);
-  static struct lm75_data lm75_update_device(struct device *dev);
-
-* [Sysctl] All sysctl stuff is of course gone (defines, ctl_table
-  and functions). Instead, you have to define show and set functions for
-  each sysfs file. Only define set for writable values. Take a look at an
-  existing 2.6 driver for details (it87 for example). Don't forget
-  to define the attributes for each file (this is that step that
-  links callback functions). Use the file names specified in
-  Documentation/hwmon/sysfs-interface for the individual files. Also
-  convert the units these files read and write to the specified ones.
-  If you need to add a new type of file, please discuss it on the
-  sensors mailing list <lm-sensors@lm-sensors.org> by providing a
-  patch to the Documentation/hwmon/sysfs-interface file.
-
-* [Attach] The attach function should make sure that the adapter's
-  class has I2C_CLASS_HWMON (or whatever class is suitable for your
-  driver), using the following construct:
-  if (!(adapter->class & I2C_CLASS_HWMON))
-          return 0;
-  Call i2c_probe() instead of i2c_detect().
-
-* [Detect] As mentioned earlier, the flags parameter is gone.
-  The type_name and client_name strings are replaced by a single
-  name string, which will be filled with a lowercase, short string.
-  The labels used for error paths are reduced to the number needed.
-  It is advised that the labels are given descriptive names such as
-  exit and exit_free. Don't forget to properly set err before
-  jumping to error labels. By the way, labels should be left-aligned.
-  Use kzalloc instead of kmalloc.
-  Use i2c_set_clientdata to set the client data (as opposed to
-  a direct access to client->data).
-  Use strlcpy instead of strcpy or snprintf to copy the client name.
-  Replace the sysctl directory registration by calls to
-  device_create_file. Move the driver initialization before any
-  sysfs file creation.
-  Register the client with the hwmon class (using hwmon_device_register)
-  if applicable.
-  Drop client->id.
-  Drop any 24RF08 corruption prevention you find, as this is now done
-  at the i2c-core level, and doing it twice voids it.
-  Don't add I2C_CLIENT_ALLOW_USE to client->flags, it's the default now.
-
-* [Init] Limits must not be set by the driver (can be done later in
-  user-space). Chip should not be reset default (although a module
-  parameter may be used to force it), and initialization should be
-  limited to the strictly necessary steps.
-
-* [Detach] Remove the call to i2c_deregister_entry. Do not log an
-  error message if i2c_detach_client fails, as i2c-core will now do
-  it for you.
-  Unregister from the hwmon class if applicable.
-
-* [Update] The function prototype changed, it is now
-  passed a device structure, which you have to convert to a client
-  using to_i2c_client(dev). The update function should return a
-  pointer to the client data.
-  Don't access client->data directly, use i2c_get_clientdata(client)
-  instead.
-  Use time_after() instead of direct jiffies comparison.
-
-* [Interface] Make sure there is a MODULE_LICENSE() line, at the bottom
-  of the file (after MODULE_AUTHOR() and MODULE_DESCRIPTION(), in this
-  order).
-
-* [Driver] The flags field of the i2c_driver structure is gone.
-  I2C_DF_NOTIFY is now the default behavior.
-  The i2c_driver structure has a driver member, which is itself a
-  structure, those name member should be initialized to a driver name
-  string. i2c_driver itself has no name member anymore.
-
-* [Driver model] Instead of shutdown or reboot notifiers, provide a
-  shutdown() method in your driver.
-
-* [Power management] Use the driver model suspend() and resume()
-  callbacks instead of the obsolete pm_register() calls.
-
-Coding policy:
-
-* [Copyright] Use (C), not (c), for copyright.
-
-* [Debug/log] Get rid of #ifdef DEBUG/#endif constructs whenever you
-  can. Calls to printk for debugging purposes are replaced by calls to
-  dev_dbg where possible, else to pr_debug. Here is an example of how
-  to call it (taken from lm75_detect):
-  dev_dbg(&client->dev, "Starting lm75 update\n");
-  Replace other printk calls with the dev_info, dev_err or dev_warn
-  function, as appropriate.
-
-* [Constants] Constants defines (registers, conversions) should be
-  aligned. This greatly improves readability.
-  Alignments are achieved by the means of tabs, not spaces. Remember
-  that tabs are set to 8 in the Linux kernel code.
-
-* [Layout] Avoid extra empty lines between comments and what they
-  comment. Respect the coding style (see Documentation/CodingStyle),
-  in particular when it comes to placing curly braces.
-
-* [Comments] Make sure that no comment refers to a file that isn't
-  part of the Linux source tree (typically doc/chips/<chip name>),
-  and that remaining comments still match the code. Merging comment
-  lines when possible is encouraged.

+Initializing the driver
+=======================
+
+When the kernel is booted, or when your foo driver module is inserted,
+you have to do some initializing. Fortunately, just registering the
+driver module is usually enough.
 
-Most i2c devices can be present on several i2c addresses; for some this
-is determined in hardware (by soldering some chip pins to Vcc or Ground),
-for others this can be changed in software (by writing to specific client
-registers). Some devices are usually on a specific address, but not always;
-and some are even more tricky. So you will probably need to scan several
-i2c addresses for your clients, and do some sort of detection to see
-whether it is actually a device supported by your driver.

+MODULE_DESCRIPTION("Driver for Barf Inc. Foo I2C devices");
 
-To give the user a maximum of possibilities, some default module parameters
-are defined to help determine what addresses are scanned. Several macros
-are defined in i2c.h to help you support them, as well as a generic
-detection algorithm.
-
-You do not have to use this parameter interface; but don't try to use
-function i2c_probe() if you don't.
-
-
-Probing classes (Legacy model)
-------------------------------
-
-All parameters are given as lists of unsigned 16-bit integers. Lists are
-terminated by I2C_CLIENT_END.
-The following lists are used internally:
-
-  normal_i2c: filled in by the module writer. 
-     A list of I2C addresses which should normally be examined.
-   probe: insmod parameter. 
-     A list of pairs. The first value is a bus number (-1 for any I2C bus), 
-     the second is the address. These addresses are also probed, as if they 
-     were in the 'normal' list.
-   ignore: insmod parameter.
-     A list of pairs. The first value is a bus number (-1 for any I2C bus), 
-     the second is the I2C address. These addresses are never probed. 
-     This parameter overrules the 'normal_i2c' list only.
-   force: insmod parameter. 
-     A list of pairs. The first value is a bus number (-1 for any I2C bus),
-     the second is the I2C address. A device is blindly assumed to be on
-     the given address, no probing is done. 
-
-Additionally, kind-specific force lists may optionally be defined if
-the driver supports several chip kinds. They are grouped in a
-NULL-terminated list of pointers named forces, those first element if the
-generic force list mentioned above. Each additional list correspond to an
-insmod parameter of the form force_<kind>.
-
-Fortunately, as a module writer, you just have to define the `normal_i2c' 
-parameter. The complete declaration could look like this:
-
-  /* Scan 0x4c to 0x4f */
-  static const unsigned short normal_i2c[] = { 0x4c, 0x4d, 0x4e, 0x4f,
-                                               I2C_CLIENT_END };
-
-  /* Magic definition of all other variables and things */
-  I2C_CLIENT_INSMOD;
-  /* Or, if your driver supports, say, 2 kind of devices: */
-  I2C_CLIENT_INSMOD_2(foo, bar);
-
-If you use the multi-kind form, an enum will be defined for you:
-  enum chips { any_chip, foo, bar, ... }
-You can then (and certainly should) use it in the driver code.
-
-Note that you *have* to call the defined variable `normal_i2c',
-without any prefix!
-
-
-Attaching to an adapter (Legacy model)
---------------------------------------
-
-Whenever a new adapter is inserted, or for all adapters if the driver is
-being registered, the callback attach_adapter() is called. Now is the
-time to determine what devices are present on the adapter, and to register
-a client for each of them.
-
-The attach_adapter callback is really easy: we just call the generic
-detection function. This function will scan the bus for us, using the
-information as defined in the lists explained above. If a device is
-detected at a specific address, another callback is called.
-
-  int foo_attach_adapter(struct i2c_adapter *adapter)
-  {
-    return i2c_probe(adapter,&addr_data,&foo_detect_client);
-  }
-
-Remember, structure `addr_data' is defined by the macros explained above,
-so you do not have to define it yourself.
-
-The i2c_probe function will call the foo_detect_client
-function only for those i2c addresses that actually have a device on
-them (unless a `force' parameter was used). In addition, addresses that
-are already in use (by some other registered client) are skipped.
-
-
-The detect client function (Legacy model)
------------------------------------------
-
-The detect client function is called by i2c_probe. The `kind' parameter
-contains -1 for a probed detection, 0 for a forced detection, or a positive
-number for a forced detection with a chip type forced.
-
-Returning an error different from -ENODEV in a detect function will cause
-the detection to stop: other addresses and adapters won't be scanned.
-This should only be done on fatal or internal errors, such as a memory
-shortage or i2c_attach_client failing.
-
-For now, you can ignore the `flags' parameter. It is there for future use.

+       --------------------------------------------------------
+
+This recipe describes how to get xen-ia64 source and build it,
+and run domU with pv_ops.
+
+============
+Requirements
+============
+
+  - python
+  - mercurial
+    it (aka "hg") is an open-source source code
+    management software. See the below.
+    http://www.selenic.com/mercurial/wiki/
+  - git
+  - bridge-utils
+
+=================================
+Getting and Building Xen and Dom0
+=================================
+
+  My environment is;
+    Machine  : Tiger4
+    Domain0 OS  : RHEL5
+    DomainU OS  : RHEL5
+
+ 1. Download source
+    # hg clone http://xenbits.xensource.com/ext/ia64/xen-unstable.hg
+    # cd xen-unstable.hg
+    # hg clone http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg
+
+ 2. # make world
+
+ 3. # make install-tools
+
+ 4. copy kernels and xen
+    # cp xen/xen.gz /boot/efi/efi/redhat/
+    # cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
+      /boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
+
+ 5. make initrd for Dom0/DomU
+    # make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
+      O=$(/bin/pwd)/build-linux-2.6.18-xen_ia64
+    # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.18.8-xen.img \
+      2.6.18.8-xen --builtin mptspi --builtin mptbase \
+      --builtin mptscsih --builtin uhci-hcd --builtin ohci-hcd \
+      --builtin ehci-hcd
+
+================================
+Making a disk image for guest OS
+================================
+
+ 1. make file
+    # dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
+    # mke2fs -F -j /root/rhel5.img
+    # mount -o loop /root/rhel5.img /mnt
+    # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
+    # mkdir /mnt/{root,proc,sys,home,tmp}
+
+    Note: You may miss some device files. If so, please create them
+    with mknod. Or you can use tar instead of cp.
+
+ 2. modify DomU's fstab
+    # vi /mnt/etc/fstab
+       /dev/xvda1  /            ext3    defaults        1 1
+       none        /dev/pts     devpts  gid=5,mode=620  0 0
+       none        /dev/shm     tmpfs   defaults        0 0
+       none        /proc        proc    defaults        0 0
+       none        /sys         sysfs   defaults        0 0
+
+ 3. modify inittab
+    set runlevel to 3 to avoid X trying to start
+    # vi /mnt/etc/inittab
+       id:3:initdefault:
+    Start a getty on the hvc0 console
+       X0:2345:respawn:/sbin/mingetty hvc0
+    tty1-6 mingetty can be commented out
+
+ 4. add hvc0 into /etc/securetty
+    # vi /mnt/etc/securetty (add hvc0)
+
+ 5. umount
+    # umount /mnt
+
+FYI, virt-manager can also make a disk image for guest OS.
+It's GUI tools and easy to make it.
+
+==================
+Boot Xen & Domain0
+==================
+
+ 1. replace elilo
+    elilo of RHEL5 can boot Xen and Dom0.
+    If you use old elilo (e.g RHEL4), please download from the below
+    http://elilo.sourceforge.net/cgi-bin/blosxom
+    and copy into /boot/efi/efi/redhat/
+    # cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
+
+ 2. modify elilo.conf (like the below)
+    # vi /boot/efi/efi/redhat/elilo.conf
+     prompt
+     timeout=20
+     default=xen
+     relocatable
+
+     image=vmlinuz-2.6.18.8-xen
+             label=xen
+             vmm=xen.gz
+             initrd=initrd-2.6.18.8-xen.img
+             read-only
+             append=" -- rhgb root=/dev/sda2"
+
+The append options before "--" are for xen hypervisor,
+the options after "--" are for dom0.
+
+FYI, your machine may need console options like
+"com1=19200,8n1 console=vga,com1". For example,
+append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
+console=ttyS0 root=/dev/sda2"
+
+=====================================
+Getting and Building domU with pv_ops

+    (Note: The current branch is xen-ia64-domu-minimal-2008may19.
+    But you would find the new branch. You can see with
+    "git branch -r" to get the branch lists.

+    is also available. The tree is based on
+    git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
+
+
+ 3. copy .config for pv_ops of domU
+    # cp arch/ia64/configs/xen_domu_wip_defconfig .config
+
+ 4. make kernel with pv_ops
+    # make oldconfig
+    # make
+
+ 5. install the kernel and initrd
+    # cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
+    # make modules_install
+    # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \

+Boot DomainU with pv_ops
+========================
+
+ 1. make config of DomU
+   # vi /etc/xen/rhel5
+     kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"

+     root = "/dev/xvda1 ro"
+     extra= "rhgb console=hvc0"
+
+ 2. After boot xen and dom0, start xend
+   # /etc/init.d/xend start
+   ( In the debugging case, # XEND_DEBUG=1 xend trace_start )
+
+ 3. start domU
+   # xm create -c rhel5

+
+
+    Introduction
+
+UWB is a wide-band communication protocol that is to serve also as the
+low-level protocol for others (much like TCP sits on IP). Currently
+these others are Wireless USB and TCP/IP, but seems Bluetooth and
+Firewire/1394 are coming along.
+
+UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of
+~-41dB (or 0.074 uW/MHz--geography specific data is still being
+negotiated w/ regulators, so watch for changes). That band is divided in
+a bunch of ~1.5 GHz wide channels (or band groups) composed of three
+subbands/subchannels (528 MHz each). Each channel is independent of each
+other, so you could consider them different "busses". Initially this
+driver considers them all a single one.
+
+Radio time is divided in 65536 us long /superframes/, each one divided
+in 256 256us long /MASs/ (Media Allocation Slots), which are the basic
+time/media allocation units for transferring data. At the beginning of
+each superframe there is a Beacon Period (BP), where every device
+transmit its beacon on a single MAS. The length of the BP depends on how
+many devices are present and the length of their beacons.
+
+Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16
+bit address) and send periodic beacons to advertise themselves and pass
+info on what they are and do. They advertise their capabilities and a
+bunch of other stuff.
+
+The different logical parts of this driver are:
+
+    *
+
+      *UWB*: the Ultra-Wide-Band stack -- manages the radio and
+      associated spectrum to allow for devices sharing it. Allows to
+      control bandwidth assingment, beaconing, scanning, etc
+
+    *
+
+      *WUSB*: the layer that sits on top of UWB to provide Wireless USB.
+      The Wireless USB spec defines means to control a UWB radio and to
+      do the actual WUSB.
+
+
+      HWA: Host Wire adapters, your Wireless USB dongle
+
+WUSB also defines a device called a Host Wire Adaptor (HWA), which in
+mere terms is a USB dongle that enables your PC to have UWB and Wireless
+USB. The Wireless USB Host Controller in a HWA looks to the host like a
+[Wireless] USB controller connected via USB (!)
+
+The HWA itself is broken in two or three main interfaces:
+
+    *
+
+      *RC*: Radio control -- this implements an interface to the
+      Ultra-Wide-Band radio controller. The driver for this implements a
+      USB-based UWB Radio Controller to the UWB stack.
+
+    *
+
+      *HC*: the wireless USB host controller. It looks like a USB host
+      whose root port is the radio and the WUSB devices connect to it.
+      To the system it looks like a separate USB host. The driver (will)
+      implement a USB host controller (similar to UHCI, OHCI or EHCI)
+      for which the root hub is the radio...To reiterate: it is a USB
+      controller that is connected via USB instead of PCI.
+
+    *
+
+      *WINET*: some HW provide a WiNET interface (IP over UWB). This
+      package provides a driver for it (it looks like a network
+      interface, winetX). The driver detects when there is a link up for
+      their type and kick into gear.
+
+
+      DWA: Device Wired Adaptor, a Wireless USB hub for wired devices
+
+These are the complement to HWAs. They are a USB host for connecting
+wired devices, but it is connected to your PC connected via Wireless
+USB. To the system it looks like yet another USB host. To the untrained
+eye, it looks like a hub that connects upstream wirelessly.
+
+We still offer no support for this; however, it should share a lot of
+code with the HWA-RC driver; there is a bunch of factorization work that
+has been done to support that in upcoming releases.
+
+
+      WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter
+
+This is your usual PCI device that implements WHCI. Similar in concept
+to EHCI, it allows your wireless USB devices (including DWAs) to connect
+to your host via a PCI interface. As in the case of the HWA, it has a
+Radio Control interface and the WUSB Host Controller interface per se.
+
+There is still no driver support for this, but will be in upcoming
+releases.
+
+
+    The UWB stack
+
+The main mission of the UWB stack is to keep a tally of which devices
+are in radio proximity to allow drivers to connect to them. As well, it
+provides an API for controlling the local radio controllers (RCs from
+now on), such as to start/stop beaconing, scan, allocate bandwidth, etc.
+
+
+      Devices and hosts: the basic structure
+
+The main building block here is the UWB device (struct uwb_dev). For
+each device that pops up in radio presence (ie: the UWB host receives a
+beacon from it) you get a struct uwb_dev that will show up in
+/sys/class/uwb and in /sys/bus/uwb/devices.
+
+For each RC that is detected, a new struct uwb_rc is created. In turn, a
+RC is also a device, so they also show in /sys/class/uwb and
+/sys/bus/uwb/devices, but at the same time, only radio controllers show
+up in /sys/class/uwb_rc.
+
+    *
+
+      [*] The reason for RCs being also devices is that not only we can
+      see them while enumerating the system device tree, but also on the
+      radio (their beacons and stuff), so the handling has to be
+      likewise to that of a device.
+
+Each RC driver is implemented by a separate driver that plugs into the
+interface that the UWB stack provides through a struct uwb_rc_ops. The
+spec creators have been nice enough to make the message format the same
+for HWA and WHCI RCs, so the driver is really a very thin transport that
+moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/]
+and sends the replies and notifications back to the API
+[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that
+is chartered, among other things, to keep the tab of how the UWB radio
+neighborhood looks, creating and destroying devices as they show up or
+dissapear.
+
+Command execution is very simple: a command block is sent and a event
+block or reply is expected back. For sending/receiving command/events, a
+handle called /neh/ (Notification/Event Handle) is opened with
+/uwb_rc_neh_open()/.
+
+The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for
+the USB connected HWA. Eventually, drivers/whci-rc.c will do the same
+for the PCI connected WHCI controller.
+
+
+      Host Controller life cycle
+
+So let's say we connect a dongle to the system: it is detected and
+firmware uploaded if needed [for Intel's i1480
+/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated.
+Now we have a real HWA device connected and
+/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the
+Wire-Adaptor environment and then suck it into the UWB stack's vision of
+the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/].
+
+    *
+
+      [*] The stack should put a new RC to scan for devices
+      [/uwb_rc_scan()/] so it finds what's available around and tries to
+      connect to them, but this is policy stuff and should be driven
+      from user space. As of now, the operator is expected to do it
+      manually; see the release notes for documentation on the procedure.
+
+When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/
+takes time of tearing everything down safely (or not...).
+
+
+      On the air: beacons and enumerating the radio neighborhood
+
+So assuming we have devices and we have agreed for a channel to connect
+on (let's say 9), we put the new RC to beacon:
+
+    *
+
+            $ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon
+
+Now it is visible. If there were other devices in the same radio channel
+and beacon group (that's what the zero is for), the dongle's radio
+control interface will send beacon notifications on its
+notification/event endpoint (NEEP). The beacon notifications are part of
+the event stream that is funneled into the API with
+/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB
+daemon through a notification list.
+
+UWBD wakes up and scans the event list; finds a beacon and adds it to
+the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from
+the same device, he considers it to be 'onair' and creates a new device
+[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons
+are received in some time, the device is considered gone and wiped out
+[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge
+the beacon cache of dead devices].
+
+
+      Device lists
+
+All UWB devices are kept in the list of the struct bus_type uwb_bus.
+
+
+      Bandwidth allocation
+
+The UWB stack maintains a local copy of DRP availability through
+processing of incoming *DRP Availability Change* notifications. This
+local copy is currently used to present the current bandwidth
+availability to the user through the sysfs file
+/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth
+availability information will be used by the bandwidth reservation
+routines.
+
+The bandwidth reservation routines are in progress and are thus not
+present in the current release. When completed they will enable a user
+to initiate DRP reservation requests through interaction with sysfs. DRP
+reservation requests from remote UWB devices will also be handled. The
+bandwidth management done by the UWB stack will include callbacks to the
+higher layers will enable the higher layers to use the reservations upon
+completion. [Note: The bandwidth reservation work is in progress and
+subject to change.]
+
+
+    Wireless USB Host Controller drivers
+
+*WARNING* This section needs a lot of work!
+
+As explained above, there are three different types of HCs in the WUSB
+world: HWA-HC, DWA-HC and WHCI-HC.
+
+HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB
+connected controllers), and their transfer management system is almost
+identical. So is their notification delivery system.
+
+HWA-HC and WHCI-HC share that they are both WUSB host controllers, so
+they have to deal with WUSB device life cycle and maintenance, wireless
+root-hub
+
+HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has
+three endpoints (Notifications, Data Transfer In and Data Transfer
+Out--known as NEP, DTI and DTO in the code).
+
+We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster
+ID and tell the HC to use all that. Then we start it. This means the HC
+starts sending MMCs.
+
+    *
+
+      The MMCs are blocks of data defined somewhere in the WUSB1.0 spec
+      that define a stream in the UWB channel time allocated for sending
+      WUSB IEs (host to device commands/notifications) and Device
+      Notifications (device initiated to host). Each host defines a
+      unique Wireless USB cluster through MMCs. Devices can connect to a
+      single cluster at the time. The IEs are Information Elements, and
+      among them are the bandwidth allocations that tell each device
+      when can they transmit or receive.
+
+Now it all depends on external stimuli.
+
+*New device connection*
+
+A new device pops up, it scans the radio looking for MMCs that give out
+the existence of Wireless USB channels. Once one (or more) are found,
+selects which one to connect to. Sends a /DN_Connect/ (device
+notification connect) during the DNTS (Device Notification Time
+Slot--announced in the MMCs
+
+HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery
+into /devconnect/). This process starts the authentication process for
+the device. First we allocate a /fake port/ and assign an
+unauthenticated address (128 to 255--what we really do is
+0x80 | fake_port_idx). We fiddle with the fake port status and /khubd/
+sees a new connection, so he moves on to enable the fake port with a reset.
+
+So now we are in the reset path -- we know we have a non-yet enumerated
+device with an unauthorized address; we ask user space to authenticate
+(FIXME: not yet done, similar to bluetooth pairing), then we do the key
+exchange (FIXME: not yet done) and issue a /set address 0/ to bring the
+device to the default state. Device is authenticated.
+
+From here, the USB stack takes control through the usb_hcd ops. khubd
+has seen the port status changes, as we have been toggling them. It will
+start enumerating and doing transfers through usb_hcd->urb_enqueue() to
+read descriptors and move our data.
+
+*Device life cycle and keep alives*
+
+Everytime there is a succesful transfer to/from a device, we update a
+per-device activity timestamp. If not, every now and then we check and
+if the activity timestamp gets old, we ping the device by sending it a
+Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this
+arrives to us as a notification through
+devconnect.c:wusb_handle_dn_alive(). If a device times out, we
+disconnect it from the system (cleaning up internal information and
+toggling the bits in the fake hub port, which kicks khubd into removing
+the rest of the stuff).
+
+This is done through devconnect:__wusb_check_devs(), which will scan the
+device list looking for whom needs refreshing.
+
+If the device wants to disconnect, it will either die (ugly) or send a
+/DN_Disconnect/ that will prompt a disconnection from the system.
+
+*Sending and receiving data*
+
+Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is
+/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and
+DWAs.
+
+Each HC has a number of rpipes and buffers that can be assigned to them;
+when doing a data transfer (xfer), first the rpipe has to be aimed and
+prepared (buffers assigned), then we can start queueing requests for
+data in or out.
+
+Data buffers have to be segmented out before sending--so we send first a
+header (segment request) and then if there is any data, a data buffer
+immediately after to the DTI interface (yep, even the request). If our
+buffer is bigger than the max segment size, then we just do multiple
+requests.
+
+[This sucks, because doing USB scatter gatter in Linux is resource
+intensive, if any...not that the current approach is not. It just has to
+be cleaned up a lot :)].
+
+If reading, we don't send data buffers, just the segment headers saying
+we want to read segments.
+
+When the xfer is executed, we receive a notification that says data is
+ready in the DTI endpoint (handled through
+xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a
+descriptor that gives us the status of the transfer, its identification
+(given when we issued it) and the segment number. If it was a data read,
+we issue another URB to read into the destination buffer the chunk of
+data coming out of the remote endpoint. Done, wait for the next guy. The
+callbacks for the URBs issued from here are the ones that will declare
+the xfer complete at some point and call it's callback.
+
+Seems simple, but the implementation is not trivial.
+
+    *
+
+      *WARNING* Old!!
+
+The main xfer descriptor, wa_xfer (equivalent to a URB) contains an
+array of segments, tallys on segments and buffers and callback
+information. Buried in there is a lot of URBs for executing the segments
+and buffer transfers.
+
+For OUT xfers, there is an array of segments, one URB for each, another
+one of buffer URB. When submitting, we submit URBs for segment request
+1, buffer 1, segment 2, buffer 2...etc. Then we wait on the DTI for xfer
+result data; when all the segments are complete, we call the callback to
+finalize the transfer.
+
+For IN xfers, we only issue URBs for the segments we want to read and
+then wait for the xfer result data.
+
+*URB mapping into xfers*
+
+This is done by hwahc_op_urb_[en|de]queue(). In enqueue() we aim an
+rpipe to the endpoint where we have to transmit, create a transfer
+context (wa_xfer) and submit it. When the xfer is done, our callback is
+called and we assign the status bits and release the xfer resources.
+
+In dequeue() we are basically cancelling/aborting the transfer. We issue
+a xfer abort request to the HC, cancell all the URBs we had submitted
+and not yet done and when all that is done, the xfer callback will be
+called--this will call the URB callback.

+Usage: $progname COMMAND DEVICEs [ARGS]
+
+Command for manipulating the pairing/authentication credentials of a
+Wireless USB device that supports wired-mode Cable-Based-Association.
+
+Works in conjunction with the wusb-cba.ko driver from http://linuxuwb.org.
+
+
+DEVICE
+
+ sysfs path to the device to authenticate; for example, both this
+ guys are the same:
+
+ /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.4/1-4.4:1.1
+ /sys/bus/usb/drivers/wusb-cbaf/1-4.4:1.1
+
+COMMAND/ARGS are
+
+ start
+
+   Start a WUSB host controller (by setting up a CHID)
+
+ set-chid DEVICE HOST-CHID HOST-BANDGROUP HOST-NAME
+
+   Sets host information in the device; after this you can call the
+   get-cdid to see how does this device report itself to us.
+
+ get-cdid DEVICE
+
+   Get the device ID associated to the HOST-CHDI we sent with
+   'set-chid'. We might not know about it.
+
+ set-cc DEVICE
+
+   If we allow the device to connect, set a random new CDID and CK
+   (connection key). Device saves them for the next time it wants to
+   connect wireless. We save them for that next time also so we can
+   authenticate the device (when we see the CDID he uses to id
+   itself) and the CK to crypto talk to it.
+
+CHID is always 16 hex bytes in 'XX YY ZZ...' form
+BANDGROUP is almost always 0001
+
+Examples:
+
+  You can default most arguments to '' to get a sane value:
+
+  $ $progname set-chid '' '' '' "My host name"
+
+  A full sequence:
+
+  $ $progname set-chid '' '' '' "My host name"
+  $ $progname get-cdid ''
+  $ $progname set-cc ''
+
+EOF
+}
+
+
+# Defaults
+# FIXME: CHID should come from a database :), band group from the host

-          While the User-Mode Linux port uses its own root file system for

-          access files stored on the host.  It does not require any
-          network connection between the Host and UML.  An example use of
-          this might be:
-
-          mount none /tmp/fromhost -t hostfs -o /tmp/umlshare
-
-          where /tmp/fromhost is an empty directory inside UML and
-          /tmp/umlshare is a directory on the host with files the UML user
-          wishes to access.
-
-          For more information, see
-          <http://user-mode-linux.sourceforge.net/hostfs.html>.
-
-          If you'd like to be able to work with files stored on the host,
-          say Y or M here; otherwise say N.
-
-config HPPFS
-	tristate "HoneyPot ProcFS (EXPERIMENTAL)"

-	help
-	  hppfs (HoneyPot ProcFS) is a filesystem which allows UML /proc
-	  entries to be overridden, removed, or fabricated from the host.
-	  Its purpose is to allow a UML to appear to be a physical machine
-	  by removing or changing anything in /proc which gives away the
-	  identity of a UML.
-
-	  See <http://user-mode-linux.sf.net/old/hppfs.html> for more information.
-
-	  You only need this if you are setting up a UML honeypot.  Otherwise,
-	  it is safe to say 'N' here.
-
-config MCONSOLE
-	bool "Management console"
-	default y
-	help
-          The user mode linux management console is a low-level interface to
-          the kernel, somewhat like the i386 SysRq interface.  Since there is
-          a full-blown operating system running under every user mode linux
-          instance, there is much greater flexibility possible than with the
-          SysRq mechanism.
-
-          If you answer 'Y' to this option, to use this feature, you need the
-          mconsole client (called uml_mconsole) which is present in CVS in
-          2.4.5-9um and later (path /tools/mconsole), and is also in the
-          distribution RPM package in 2.4.6 and later.
-
-          It is safe to say 'Y' here.
-
-config MAGIC_SYSRQ
-	bool "Magic SysRq key"
-	depends on MCONSOLE
-	help
-	  If you say Y here, you will have some control over the system even
-	  if the system crashes for example during kernel debugging (e.g., you
-	  will be able to flush the buffer cache to disk, reboot the system
-	  immediately or dump some status information). A key for each of the
-	  possible requests is provided.
-
-	  This is the feature normally accomplished by pressing a key
-	  while holding SysRq (Alt+PrintScreen).
-
-	  On UML, this is accomplished by sending a "sysrq" command with
-	  mconsole, followed by the letter for the requested command.
-
-	  The keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
-	  unless you really know what this hack does.
-
-config SMP
-	bool "Symmetric multi-processing support (EXPERIMENTAL)"
-	default n
-	depends on BROKEN
-	help
-	  This option enables UML SMP support.
-	  It is NOT related to having a real SMP box. Not directly, at least.
-
-	  UML implements virtual SMP by allowing as many processes to run
-	  simultaneously on the host as there are virtual processors configured.
-
-	  Obviously, if the host is a uniprocessor, those processes will
-	  timeshare, but, inside UML, will appear to be running simultaneously.
-	  If the host is a multiprocessor, then UML processes may run
-	  simultaneously, depending on the host scheduler.
-
-	  This, however, is supported only in TT mode. So, if you use the SKAS
-	  patch on your host, switching to TT mode and enabling SMP usually
-	  gives	you worse performances.
-	  Also, since the support for SMP has been under-developed, there could
-	  be some bugs being exposed by enabling SMP.
-
-	  If you don't know what to do, say N.
-
-config NR_CPUS

-	default "32"
-
-config HIGHMEM
-	bool "Highmem support (EXPERIMENTAL)"
-	depends on !64BIT && EXPERIMENTAL
-	default n
-	help
-	  This was used to allow UML to run with big amounts of memory.
-	  Currently it is unstable, so if unsure say N.
-
-	  To use big amounts of memory, it is recommended enable static
-	  linking (i.e. CONFIG_STATIC_LINK) - this should allow the
-	  guest to use up to 2.75G of memory.
-
-config KERNEL_STACK_ORDER
-	int "Kernel stack size order"
-	default 1 if 64BIT
-	range 1 10 if 64BIT
-	default 0 if !64BIT
-	help
-	  This option determines the size of UML kernel stacks.  They will
-	  be 1 << order pages.  The default is OK unless you're running Valgrind
-	  on UML, in which case, set this to 3.

+          booting and normal file access, this module lets the UML user
+          access files stored on the host.  It does not require any
+          network connection between the Host and UML.  An example use of
+          this might be:
+
+          mount none /tmp/fromhost -t hostfs -o /tmp/umlshare
+
+          where /tmp/fromhost is an empty directory inside UML and
+          /tmp/umlshare is a directory on the host with files the UML user
+          wishes to access.
+
+          For more information, see
+          <http://user-mode-linux.sourceforge.net/hostfs.html>.
+
+          If you'd like to be able to work with files stored on the host,
+          say Y or M here; otherwise say N.
+
+config HPPFS
+	tristate "HoneyPot ProcFS (EXPERIMENTAL)"
+	depends on EXPERIMENTAL
+	help
+	  hppfs (HoneyPot ProcFS) is a filesystem which allows UML /proc
+	  entries to be overridden, removed, or fabricated from the host.
+	  Its purpose is to allow a UML to appear to be a physical machine
+	  by removing or changing anything in /proc which gives away the
+	  identity of a UML.
+
+	  See <http://user-mode-linux.sf.net/old/hppfs.html> for more information.
+
+	  You only need this if you are setting up a UML honeypot.  Otherwise,
+	  it is safe to say 'N' here.
+
+config MCONSOLE
+	bool "Management console"
+	default y
+	help
+          The user mode linux management console is a low-level interface to
+          the kernel, somewhat like the i386 SysRq interface.  Since there is
+          a full-blown operating system running under every user mode linux
+          instance, there is much greater flexibility possible than with the
+          SysRq mechanism.
+
+          If you answer 'Y' to this option, to use this feature, you need the
+          mconsole client (called uml_mconsole) which is present in CVS in
+          2.4.5-9um and later (path /tools/mconsole), and is also in the
+          distribution RPM package in 2.4.6 and later.
+
+          It is safe to say 'Y' here.
+
+config MAGIC_SYSRQ
+	bool "Magic SysRq key"
+	depends on MCONSOLE
+	help
+	  If you say Y here, you will have some control over the system even
+	  if the system crashes for example during kernel debugging (e.g., you
+	  will be able to flush the buffer cache to disk, reboot the system
+	  immediately or dump some status information). A key for each of the
+	  possible requests is provided.
+
+	  This is the feature normally accomplished by pressing a key
+	  while holding SysRq (Alt+PrintScreen).
+
+	  On UML, this is accomplished by sending a "sysrq" command with
+	  mconsole, followed by the letter for the requested command.
+
+	  The keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
+	  unless you really know what this hack does.
+
+config SMP
+	bool "Symmetric multi-processing support (EXPERIMENTAL)"
+	default n
+	depends on BROKEN
+	help
+	  This option enables UML SMP support.
+	  It is NOT related to having a real SMP box. Not directly, at least.
+
+	  UML implements virtual SMP by allowing as many processes to run
+	  simultaneously on the host as there are virtual processors configured.
+
+	  Obviously, if the host is a uniprocessor, those processes will
+	  timeshare, but, inside UML, will appear to be running simultaneously.
+	  If the host is a multiprocessor, then UML processes may run
+	  simultaneously, depending on the host scheduler.
+
+	  This, however, is supported only in TT mode. So, if you use the SKAS
+	  patch on your host, switching to TT mode and enabling SMP usually
+	  gives	you worse performances.
+	  Also, since the support for SMP has been under-developed, there could
+	  be some bugs being exposed by enabling SMP.
+
+	  If you don't know what to do, say N.
+
+config NR_CPUS
+	int "Maximum number of CPUs (2-32)"
+	range 2 32
+	depends on SMP
+	default "32"
+
+config HIGHMEM
+	bool "Highmem support (EXPERIMENTAL)"
+	depends on !64BIT && EXPERIMENTAL
+	default n
+	help
+	  This was used to allow UML to run with big amounts of memory.
+	  Currently it is unstable, so if unsure say N.
+
+	  To use big amounts of memory, it is recommended enable static
+	  linking (i.e. CONFIG_STATIC_LINK) - this should allow the
+	  guest to use up to 2.75G of memory.
+
+config KERNEL_STACK_ORDER
+	int "Kernel stack size order"
+	default 1 if 64BIT
+	range 1 10 if 64BIT
+	default 0 if !64BIT
+	help
+	  This option determines the size of UML kernel stacks.  They will
+	  be 1 << order pages.  The default is OK unless you're running Valgrind
+	  on UML, in which case, set this to 3.

+ * read_barrier_depends - Flush all pending reads that subsequents reads

+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	b = 2;
+ *	memory_barrier();
+ *	p = &b;				q = p;
+ *					read_barrier_depends();
+ *					d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	a = 2;
+ *	memory_barrier();
+ *	b = 3;				y = b;
+ *					read_barrier_depends();
+ *					x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	b = 2;
+ *	memory_barrier();
+ *	p = &b;				q = p;
+ *					read_barrier_depends();
+ *					d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	a = 2;
+ *	memory_barrier();
+ *	b = 3;				y = b;
+ *					read_barrier_depends();
+ *					x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+ * - Restore default attributes when a page is freed
+ * - Guarantee that mappings other than the requested one are

+ * NOTES about DMA transfers:
+ *
+ *  controller 1: channels 0-3, byte operations, ports 00-1F
+ *  controller 2: channels 4-7, word operations, ports C0-DF
+ *
+ *  - ALL registers are 8 bits only, regardless of transfer size
+ *  - channel 4 is not used - cascades 1 into 2.
+ *  - channels 0-3 are byte - addresses/counts are for physical bytes
+ *  - channels 5-7 are word - addresses/counts are for physical words
+ *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ *  - transfer count loaded to registers is 1 less than actual count
+ *  - controller 2 offsets are all even (2x offsets for controller 1)
+ *  - page registers for 5-7 don't use data bit 0, represent 128K pages
+ *  - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ *  Address mapping for channels 0-3:
+ *
+ *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *   P7  ...  P0  A7 ... A0  A7 ... A0
+ * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
+ *
+ *  Address mapping for channels 5-7:
+ *
+ *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
+ *    |  ...  |   \   \   ... \  \  \  ... \  \
+ *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
+ *    |  ...  |     \   \   ... \  \  \  ... \
+ *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0
+ * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * x86_emulate_ops:
+ *
+ * These operations represent the instruction emulator's interface to memory.
+ * There are two categories of operation: those that act on ordinary memory
+ * regions (*_std), and those that act on memory regions known to require
+ * special treatment or emulation (*_emulated).
+ *
+ * The emulator assumes that an instruction accesses only one 'emulated memory'
+ * location, that this location is the given linear faulting address (cr2), and
+ * that this is one of the instruction's data operands. Instruction fetches and
+ * stack operations are assumed never to access emulated memory. The emulator
+ * automatically deduces which operand of a string-move operation is accessing
+ * emulated memory, and assumes that the other operand accesses normal memory.
+ *
+ * NOTES:
+ *  1. The emulator isn't very smart about emulated vs. standard memory.
+ *     'Emulated memory' access addresses should be checked for sanity.
+ *     'Normal memory' accesses may fault, and the caller must arrange to
+ *     detect and handle reentrancy into the emulator via recursive faults.
+ *     Accesses may be unaligned and may cross page boundaries.
+ *  2. If the access fails (cannot emulate, or a standard access faults) then
+ *     it is up to the memop to propagate the fault to the guest VM via
+ *     some out-of-band mechanism, unknown to the emulator. The memop signals
+ *     failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will
+ *     then immediately bail.
+ *  3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only
+ *     cmpxchg8b_emulated need support 8-byte accesses.
+ *  4. The emulator cannot handle 64-bit mode emulation on an x86/32 system.

+ * These macros are intended to wrap calls through one of the paravirt

+ * runtime.
+ *
+ * Normally, a call to a pv_op function is a simple indirect call:
+ * (pv_op_struct.operations)(args...).
+ *
+ * Unfortunately, this is a relatively slow operation for modern CPUs,
+ * because it cannot necessarily determine what the destination
+ * address is.  In this case, the address is a runtime constant, so at
+ * the very least we can patch the call to e a simple direct call, or
+ * ideally, patch an inline implementation into the callsite.  (Direct
+ * calls are essentially free, because the call and return addresses
+ * are completely predictable.)
+ *
+ * For i386, these macros rely on the standard gcc "regparm(3)" calling
+ * convention, in which the first three arguments are placed in %eax,
+ * %edx, %ecx (in that order), and the remaining arguments are placed
+ * on the stack.  All caller-save registers (eax,edx,ecx) are expected
+ * to be modified (either clobbered or used for return values).
+ * X86_64, on the other hand, already specifies a register-based calling
+ * conventions, returning at %rax, with parameteres going on %rdi, %rsi,
+ * %rdx, and %rcx. Note that for this reason, x86_64 does not need any
+ * special handling for dealing with 4 arguments, unlike i386.
+ * However, x86_64 also have to clobber all caller saved registers, which
+ * unfortunately, are quite a bit (r8 - r11)
+ *
+ * The call instruction itself is marked by placing its start address
+ * and size into the .parainstructions section, so that
+ * apply_paravirt() in arch/i386/kernel/alternative.c can do the
+ * appropriate patching under the control of the backend pv_init_ops
+ * implementation.
+ *
+ * Unfortunately there's no way to get gcc to generate the args setup
+ * for the call, and then allow the call itself to be generated by an
+ * inline asm.  Because of this, we must do the complete arg setup and
+ * return value handling from within these macros.  This is fairly
+ * cumbersome.
+ *
+ * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments.
+ * It could be extended to more arguments, but there would be little
+ * to be gained from that.  For each number of arguments, there are
+ * the two VCALL and CALL variants for void and non-void functions.
+ *
+ * When there is a return value, the invoker of the macro must specify
+ * the return type.  The macro then uses sizeof() on that type to
+ * determine whether its a 32 or 64 bit value, and places the return
+ * in the right register(s) (just %eax for 32-bit, and %edx:%eax for
+ * 64-bit). For x86_64 machines, it just returns at %rax regardless of
+ * the return value size.
+ *
+ * 64-bit arguments are passed as a pair of adjacent 32-bit arguments
+ * i386 also passes 64-bit arguments as a pair of adjacent 32-bit arguments
+ * in low,high order
+ *
+ * Small structures are passed and returned in registers.  The macro
+ * calling convention can't directly deal with this, so the wrapper
+ * functions must do this.
+ *
+ * These PVOP_* macros are only defined within this header.  This
+ * means that all uses must be wrapped in inline functions.  This also
+ * makes sure the incoming and outgoing types are always correct.

+/* rwsem.h: R/W semaphores implemented using XADD/CMPXCHG for i486+
+ *
+ * Written by David Howells (dhowells@redhat.com).
+ *
+ * Derived from asm-x86/semaphore.h
+ *
+ *
+ * The MSW of the count is the negated number of active writers and waiting
+ * lockers, and the LSW is the total number of active locks
+ *
+ * The lock count is initialized to 0 (no active and no waiting lockers).
+ *
+ * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an
+ * uncontended lock. This can be determined because XADD returns the old value.
+ * Readers increment by 1 and see a positive value when uncontended, negative
+ * if there are writers (and maybe) readers waiting (in which case it goes to
+ * sleep).
+ *
+ * The value of WAITING_BIAS supports up to 32766 waiting processes. This can
+ * be extended to 65534 by manually checking the whole MSW rather than relying
+ * on the S flag.
+ *
+ * The value of ACTIVE_BIAS supports up to 65535 active processes.
+ *
+ * This should be totally fair - if anything is waiting, a process that wants a
+ * lock will go to the back of the queue. When the currently active lock is
+ * released, if there's a writer at the front of the queue, then that and only
+ * that will be woken up; if there's a bunch of consequtive readers at the
+ * front, then they'll all be woken up, but no other readers will be.

+ * read_barrier_depends - Flush all pending reads that subsequents reads

+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	b = 2;
+ *	memory_barrier();
+ *	p = &b;				q = p;
+ *					read_barrier_depends();
+ *					d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	a = 2;
+ *	memory_barrier();
+ *	b = 3;				y = b;
+ *					read_barrier_depends();
+ *					x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user (under
+   linux we use the 'trad-core' bfd).  There are quite a number of
+   obstacles to being able to view the contents of the floating point
+   registers, and until these are solved you will not be able to view the
+   contents of them.  Actually, you can read in the core file and look at
+   the contents of the user struct to find out what the floating point
+   registers contain.
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user.
+   There are quite a number of obstacles to being able to view the
+   contents of the floating point registers, and until these are
+   solved you will not be able to view the contents of them.
+   Actually, you can read in the core file and look at the contents of
+   the user struct to find out what the floating point registers
+   contain.
+
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.  */

+/*
+ * Addressing Terminology
+ *
+ *	M       - The low M bits of a physical address represent the offset
+ *		  into the blade local memory. RAM memory on a blade is physically
+ *		  contiguous (although various IO spaces may punch holes in
+ *		  it)..
+ *
+ * 	N	- Number of bits in the node portion of a socket physical
+ * 		  address.
+ *
+ * 	NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
+ * 	 	  routers always have low bit of 1, C/MBricks have low bit
+ * 		  equal to 0. Most addressing macros that target UV hub chips
+ * 		  right shift the NASID by 1 to exclude the always-zero bit.
+ * 		  NASIDs contain up to 15 bits.
+ *
+ *	GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
+ *		  of nasids.
+ *
+ * 	PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
+ * 		  of the nasid for socket usage.
+ *
+ *
+ *  NumaLink Global Physical Address Format:
+ *  +--------------------------------+---------------------+
+ *  |00..000|      GNODE             |      NodeOffset     |
+ *  +--------------------------------+---------------------+
+ *          |<-------53 - M bits --->|<--------M bits ----->
+ *
+ *	M - number of node offset bits (35 .. 40)
+ *
+ *
+ *  Memory/UV-HUB Processor Socket Address Format:
+ *  +----------------+---------------+---------------------+
+ *  |00..000000000000|   PNODE       |      NodeOffset     |
+ *  +----------------+---------------+---------------------+
+ *                   <--- N bits --->|<--------M bits ----->
+ *
+ *	M - number of node offset bits (35 .. 40)
+ *	N - number of PNODE bits (0 .. 10)
+ *
+ *		Note: M + N cannot currently exceed 44 (x86_64) or 46 (IA64).
+ *		The actual values are configuration dependent and are set at
+ *		boot time. M & N values are set by the hardware/BIOS at boot.
+ *
+ *
+ * APICID format
+ * 	NOTE!!!!!! This is the current format of the APICID. However, code
+ * 	should assume that this will change in the future. Use functions
+ * 	in this file for all APICID bit manipulations and conversion.

+ *			l =  socket number on board
+ *			c  = core
+ *			h  = hyperthread
+ *			s  = bits that are in the SOCKET_ID CSR
+ *
+ *	Note: Processor only supports 12 bits in the APICID register. The ACPI
+ *	      tables hold all 16 bits. Software needs to be aware of this.
+ *
+ * 	      Unless otherwise specified, all references to APICID refer to

+ * The hypercall asms have to meet several constraints:
+ * - Work on 32- and 64-bit.
+ *    The two architectures put their arguments in different sets of
+ *    registers.
+ *
+ * - Work around asm syntax quirks
+ *    It isn't possible to specify one of the rNN registers in a
+ *    constraint, so we use explicit register variables to get the
+ *    args into the right place.
+ *
+ * - Mark all registers as potentially clobbered
+ *    Even unused parameters can be clobbered by the hypervisor, so we
+ *    need to make sure gcc knows it.
+ *
+ * - Avoid compiler bugs.
+ *    This is the tricky part.  Because x86_32 has such a constrained
+ *    register set, gcc versions below 4.3 have trouble generating
+ *    code when all the arg registers and memory are trashed by the
+ *    asm.  There are syntactically simpler ways of achieving the
+ *    semantics below, but they cause the compiler to crash.
+ *
+ *    The only combination I found which works is:
+ *     - assign the __argX variables first
+ *     - list all actually used parameters as "+r" (__argX)
+ *     - clobber the rest
+ *
+ * The result certainly isn't pretty, and it really shows up cpp's
+ * weakness as as macro language.  Sorry.  (But let's just give thanks
+ * there aren't more than 5 arguments...)

+ * This module validates predefined ACPI objects that appear in the namespace,
+ * at the time they are evaluated (via acpi_evaluate_object). The purpose of this
+ * validation is to detect problems with BIOS-exposed predefined ACPI objects
+ * before the results are returned to the ACPI-related drivers.
+ *
+ * There are several areas that are validated:
+ *
+ *  1) The number of input arguments as defined by the method/object in the
+ *      ASL is validated against the ACPI specification.
+ *  2) The type of the return object (if any) is validated against the ACPI
+ *      specification.
+ *  3) For returned package objects, the count of package elements is
+ *      validated, as well as the type of each package element. Nested
+ *      packages are supported.
+ *
+ * For any problems found, a warning message is issued.

- *
- *	If you are using WD drives with SATA bridges you must set the
- *	drive to "Single". "Master" will hang.
- *
- *	If you have strange problems with nVidia chipset systems please
- *	see the SI support documentation and update your system BIOS
- *	if necessary
- *
- *  The Dell DRAC4 has some interesting features including effectively hot
- *  unplugging/replugging the virtual CD interface when the DRAC is reset.
- *  This often causes drivers/ide/siimage to panic but is ok with the rather
- *  smarter code in libata.

- * Region hash
- *
- * The mirror splits itself up into discrete regions.  Each
- * region can be in one of three states: clean, dirty,
- * nosync.  There is no need to put clean regions in the hash.
- *
- * In addition to being present in the hash table a region _may_
- * be present on one of three lists.
- *
- *   clean_regions: Regions on this list have no io pending to
- *   them, they are in sync, we are no longer interested in them,
- *   they are dull.  rh_update_states() will remove them from the
- *   hash table.
- *
- *   quiesced_regions: These regions have been spun down, ready
- *   for recovery.  rh_recovery_start() will remove regions from
- *   this list and hand them to kmirrord, which will schedule the
- *   recovery io with kcopyd.
- *
- *   recovered_regions: Regions that kcopyd has successfully
- *   recovered.  rh_update_states() will now schedule any delayed
- *   io, up the recovery_count, and remove the region from the
- *   hash.
- *
- * There are 2 locks:
- *   A rw spin lock 'hash_lock' protects just the hash table,
- *   this is never held in write mode from interrupt context,
- *   which I believe means that we only have to disable irqs when
- *   doing a write lock.
- *
- *   An ordinary spin lock 'region_lock' that protects the three
- *   lists in the region_hash, with the 'state', 'list' and
- *   'bhs_delayed' fields of the regions.  This is used from irq
- *   context, so all other uses will have to suspend local irqs.

+/*-----------------------------------------------------------------
+ * Region hash
+ *
+ * The mirror splits itself up into discrete regions.  Each
+ * region can be in one of three states: clean, dirty,
+ * nosync.  There is no need to put clean regions in the hash.
+ *
+ * In addition to being present in the hash table a region _may_
+ * be present on one of three lists.
+ *
+ *   clean_regions: Regions on this list have no io pending to
+ *   them, they are in sync, we are no longer interested in them,
+ *   they are dull.  dm_rh_update_states() will remove them from the
+ *   hash table.
+ *
+ *   quiesced_regions: These regions have been spun down, ready
+ *   for recovery.  rh_recovery_start() will remove regions from
+ *   this list and hand them to kmirrord, which will schedule the
+ *   recovery io with kcopyd.
+ *
+ *   recovered_regions: Regions that kcopyd has successfully
+ *   recovered.  dm_rh_update_states() will now schedule any delayed
+ *   io, up the recovery_count, and remove the region from the
+ *   hash.
+ *
+ * There are 2 locks:
+ *   A rw spin lock 'hash_lock' protects just the hash table,
+ *   this is never held in write mode from interrupt context,
+ *   which I believe means that we only have to disable irqs when
+ *   doing a write lock.
+ *
+ *   An ordinary spin lock 'region_lock' that protects the three
+ *   lists in the region_hash, with the 'state', 'list' and
+ *   'delayed_bios' fields of the regions.  This is used from irq
+ *   context, so all other uses will have to suspend local irqs.

+ * TWL4030 IRQ handling has two stages in hardware, and thus in software.

+ * enable/disable and trigger controls; they do most of the work.
+ *
+ * These chips are designed to support IRQ handling from two different
+ * I2C masters.  Each has a dedicated IRQ line, and dedicated IRQ status
+ * and mask registers in the PIH and SIH modules.
+ *
+ * We set up IRQs starting at a platform-specified base, always starting
+ * with PIH and the SIH for PWR_INT and then usually adding GPIO:
+ *	base + 0  .. base + 7	PIH
+ *	base + 8  .. base + 15	SIH for PWR_INT

+ *
+ * The HWA driver is a simple layer that forwards requests to the WAHC
+ * (Wire Adater Host Controller) or WUSBHC (Wireless USB Host
+ * Controller) layers.
+ *
+ * Host Wire Adapter is the 'WUSB 1.0 standard' name for Wireless-USB
+ * Host Controller that is connected to your system via USB (a USB
+ * dongle that implements a USB host...). There is also a Device Wired
+ * Adaptor, DWA (Wireless USB hub) that uses the same mechanism for
+ * transferring data (it is after all a USB host connected via
+ * Wireless USB), we have a common layer called Wire Adapter Host
+ * Controller that does all the hard work. The WUSBHC (Wireless USB
+ * Host Controller) is the part common to WUSB Host Controllers, the
+ * HWA and the PCI-based one, that is implemented following the WHCI
+ * spec. All these layers are implemented in ../wusbcore.
+ *
+ * The main functions are hwahc_op_urb_{en,de}queue(), that pass the
+ * job of converting a URB to a Wire Adapter
+ *
+ * Entry points:
+ *
+ *   hwahc_driver_*()   Driver initialization, registration and
+ *                      teardown.
+ *
+ *   hwahc_probe()	New device came up, create an instance for
+ *                      it [from device enumeration].
+ *
+ *   hwahc_disconnect()	Remove device instance [from device
+ *                      enumeration].
+ *
+ *   [__]hwahc_op_*()   Host-Wire-Adaptor specific functions for
+ *                      starting/stopping/etc (some might be made also
+ *                      DWA).

+ *
+ *
+ * WUSB devices have to be paired (associated in WUSB lingo) so
+ * that they can connect to the system.
+ *
+ * One way of pairing is using CBA-Cable Based Association. First
+ * time you plug the device with a cable, association is done between
+ * host and device and subsequent times, you can connect wirelessly
+ * without having to associate again. That's the idea.
+ *
+ * This driver does nothing Earth shattering. It just provides an
+ * interface to chat with the wire-connected device so we can get a
+ * CDID (device ID) that might have been previously associated to a
+ * CHID (host ID) and to set up a new <CHID,CDID,CK> triplet
+ * (connection context), with the CK being the secret, or connection
+ * key. This is the pairing data.
+ *
+ * When a device with the CBA capability connects, the probe routine
+ * just creates a bunch of sysfs files that a user space enumeration
+ * manager uses to allow it to connect wirelessly to the system or not.
+ *
+ * The process goes like this:
+ *
+ * 1. Device plugs, cbaf is loaded, notifications happen.
+ *
+ * 2. The connection manager (CM) sees a device with CBAF capability
+ *    (the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
+ *
+ * 3. The CM writes the host name, supported band groups, and the CHID
+ *    (host ID) into the wusb_host_name, wusb_host_band_groups and
+ *    wusb_chid files. These get sent to the device and the CDID (if
+ *    any) for this host is requested.
+ *
+ * 4. The CM can verify that the device's supported band groups
+ *    (wusb_device_band_groups) are compatible with the host.
+ *
+ * 5. The CM reads the wusb_cdid file.
+ *
+ * 6. The CM looks up its database
+ *
+ * 6.1 If it has a matching CHID,CDID entry, the device has been
+ *     authorized before (paired) and nothing further needs to be
+ *     done.
+ *
+ * 6.2 If the CDID is zero (or the CM doesn't find a matching CDID in
+ *     its database), the device is assumed to be not known.  The CM
+ *     may associate the host with device by: writing a randomly
+ *     generated CDID to wusb_cdid and then a random CK to wusb_ck
+ *     (this uploads the new CC to the device).
+ *
+ *     CMD may choose to prompt the user before associating with a new
+ *     device.
+ *
+ * 7. Device is unplugged.
+ *
+ * When the device tries to connect wirelessly, it will present its
+ * CDID to the WUSB host controller.  The CM will query the
+ * database. If the CHID/CDID pair found, it will (with a 4-way
+ * handshake) challenge the device to demonstrate it has the CK secret
+ * key (from our database) without actually exchanging it. Once
+ * satisfied, crypto keys are derived from the CK, the device is
+ * connected and all communication is encrypted.

+ * Linux Crypto API.
+ *
+ * We leave a crypto test module so we can verify that vectors match,

+ *

+ *
+ * Still not very clear how this is done, but looks like this: we

+ * @key. We bytewise xor B0 with B1 (1) and AES-crypt that. Then we
+ * take the payload and divide it in blocks (16 bytes), xor them with
+ * the previous crypto result (16 bytes) and crypt it, repeat the next
+ * block with the output of the previous one, rinse wash (I guess this
+ * is what AES CBC mode means...but I truly have no idea). So we use
+ * the CBC(AES) blkcipher, that does precisely that. The IV (Initial
+ * Vector) is 16 bytes and is set to zero, so
+ *
+ * See rfc3610. Linux crypto has a CBC implementation, but the
+ * documentation is scarce, to say the least, and the example code is
+ * so intricated that is difficult to understand how things work. Most
+ * of this is guess work -- bite me.
+ *
+ * (1) Created as 6.5 says, again, using as l(a) 'Blen + 14', and
+ *     using the 14 bytes of @a to fill up
+ *     b1.{mac_header,e0,security_reserved,padding}.
+ *
+ * NOTE: The definiton of l(a) in WUSB1.0[6.5] vs the definition of
+ *       l(m) is orthogonal, they bear no relationship, so it is not
+ *       in conflict with the parameter's relation that
+ *       WUSB1.0[6.4.2]) defines.
+ *
+ * NOTE: WUSB1.0[A.1]: Host Nonce is missing a nibble? (1e); fixed in
+ *       first errata released on 2005/07.
+ *
+ * NOTE: we need to clean IV to zero at each invocation to make sure
+ *       we start with a fresh empty Initial Vector, so that the CBC
+ *       works ok.
+ *
+ * NOTE: blen is not aligned to a block size, we'll pad zeros, that's
+ *       what sg[4] is for. Maybe there is a smarter way to do this.

+ *
+ *
+ * WUSB1.0[7.1, 7.5.1, ]
+ *
+ * WUSB device connection is kind of messy. Some background:
+ *
+ *     When a device wants to connect it scans the UWB radio channels
+ *     looking for a WUSB Channel; a WUSB channel is defined by MMCs
+ *     (Micro Managed Commands or something like that) [see
+ *     Design-overview for more on this] .
+ *
+ * So, device scans the radio, finds MMCs and thus a host and checks
+ * when the next DNTS is. It sends a Device Notification Connect
+ * (DN_Connect); the host picks it up (through nep.c and notif.c, ends
+ * up in wusb_devconnect_ack(), which creates a wusb_dev structure in
+ * wusbhc->port[port_number].wusb_dev), assigns an unauth address
+ * to the device (this means from 0x80 to 0xfe) and sends, in the MMC
+ * a Connect Ack Information Element (ConnAck IE).
+ *
+ * So now the device now has a WUSB address. From now on, we use
+ * that to talk to it in the RPipes.
+ *
+ * ASSUMPTIONS:
+ *
+ *  - We use the the as device address the port number where it is
+ *    connected (port 0 doesn't exist). For unauth, it is 128 + that.
+ *
+ * ROADMAP:
+ *
+ *   This file contains the logic for doing that--entry points:
+ *
+ *   wusb_devconnect_ack()      Ack a device until _acked() called.
+ *                              Called by notif.c:wusb_handle_dn_connect()
+ *                              when a DN_Connect is received.
+ *
+ *   wusbhc_devconnect_auth()   Called by rh.c:wusbhc_rh_port_reset() when
+ *                              doing the device connect sequence.
+ *
+ *     wusb_devconnect_acked()  Ack done, release resources.
+ *
+ *   wusb_handle_dn_alive()     Called by notif.c:wusb_handle_dn()
+ *                              for processing a DN_Alive pong from a device.
+ *
+ *   wusb_handle_dn_disconnect()Called by notif.c:wusb_handle_dn() to
+ *                              process a disconenct request from a
+ *                              device.
+ *
+ *   wusb_dev_reset()           Called by rh.c:wusbhc_rh_port_reset() when
+ *                              resetting a device.
+ *
+ *   __wusb_dev_disable()       Called by rh.c:wusbhc_rh_clear_port_feat() when
+ *                              disabling a port.
+ *
+ *   wusb_devconnect_create()   Called when creating the host by
+ *                              lc.c:wusbhc_create().
+ *
+ *   wusb_devconnect_destroy()  Cleanup called removing the host. Called
+ *                              by lc.c:wusbhc_destroy().
+ *
+ *   Each Wireless USB host maintains a list of DN_Connect requests
+ *   (actually we maintain a list of pending Connect Acks, the
+ *   wusbhc->ca_list).
+ *
+ * LIFE CYCLE OF port->wusb_dev
+ *
+ *   Before the @wusbhc structure put()s the reference it owns for

+ * We fake a root hub that has fake ports (as many as simultaneous

+ *
+ * Note this is common to WHCI and HWA host controllers.

+ * Through here we enable most of the state changes that the USB stack

+ * forced adaptation of Wireless USB device states vs. wired:
+ *
+ *        USB:                 WUSB:

+ *
+ *
+ * This driver implements a USB Host Controller (struct usb_hcd) for a
+ * Wireless USB Host Controller based on the Wireless USB 1.0
+ * Host-Wire-Adapter specification (in layman terms, a USB-dongle that
+ * implements a Wireless USB host).
+ *
+ * Check out the Design-overview.txt file in the source documentation
+ * for other details on the implementation.
+ *
+ * Main blocks:
+ *
+ *  driver     glue with the driver API, workqueue daemon
+ *
+ *  lc         RC instance life cycle management (create, destroy...)
+ *
+ *  hcd        glue with the USB API Host Controller Interface API.
+ *
+ *  nep        Notification EndPoint managent: collect notifications
+ *             and queue them with the workqueue daemon.
+ *
+ *             Handle notifications as coming from the NEP. Sends them
+ *             off others to their respective modules (eg: connect,
+ *             disconnect and reset go to devconnect).
+ *
+ *  rpipe      Remote Pipe management; rpipe is what we use to write
+ *             to an endpoint on a WUSB device that is connected to a
+ *             HWA RC.
+ *
+ *  xfer       Transfer managment -- this is all the code that gets a
+ *             buffer and pushes it to a device (or viceversa). *
+ *
+ * Some day a lot of this code will be shared between this driver and
+ * the drivers for DWA (xfer, rpipe).
+ *
+ * All starts at driver.c:hwahc_probe(), when one of this guys is
+ * connected. hwahc_disconnect() stops it.
+ *
+ * During operation, the main driver is devices connecting or
+ * disconnecting. They cause the HWA RC to send notifications into
+ * nep.c:hwahc_nep_cb() that will dispatch them to
+ * notif.c:wa_notif_dispatch(). From there they will fan to cause
+ * device connects, disconnects, etc.
+ *
+ * Note much of the activity is difficult to follow. For example a
+ * device connect goes to devconnect, which will cause the "fake" root
+ * hub port to show a connect and stop there. Then khubd will notice
+ * and call into the rh.c:hwahc_rc_port_reset() code to authenticate
+ * the device (and this might require user intervention) and enable
+ * the port.
+ *
+ * We also have a timer workqueue going from devconnect.c that
+ * schedules in hwahc_devconnect_create().
+ *
+ * The rest of the traffic is in the usual entry points of a USB HCD,
+ * which are hooked up in driver.c:hwahc_rc_driver, and defined in
+ * hcd.c.

+ * This part takes care of getting the notification from the hw
+ * only and dispatching through wusbwad into
+ * wa_notif_dispatch. Handling is done there.
+ *
+ * WA notifications are limited in size; most of them are three or
+ * four bytes long, and the longest is the HWA Device Notification,
+ * which would not exceed 38 bytes (DNs are limited in payload to 32
+ * bytes plus 3 bytes header (WUSB1.0[7.6p2]), plus 3 bytes HWA
+ * header (WUSB1.0[8.5.4.2]).
+ *
+ * It is not clear if more than one Device Notification can be packed
+ * in a HWA Notification, I assume no because of the wording in
+ * WUSB1.0[8.5.4.2]. In any case, the bigger any notification could
+ * get is 256 bytes (as the bLength field is a byte).
+ *
+ * So what we do is we have this buffer and read into it; when a
+ * notification arrives we schedule work to a specific, single thread
+ * workqueue (so notifications are serialized) and copy the
+ * notification data. After scheduling the work, we rearm the read from
+ * the notification endpoint.
+ *
+ * Entry points here are:

+ * wa_nep_[create|destroy]()   To initialize/release this subsystem
+ *
+ * wa_nep_cb()                 Callback for the notification
+ *                                endpoint; when data is ready, this
+ *                                does the dispatching.

+ *
+ *   The number of blocks could be dynamic (wBlocks in descriptor is
+ *   0)--need to schedule them then.
+ *
+ * Each bit in wa->rpipe_bm represents if an rpipe is being used or
+ * not. Rpipes are represented with a 'struct wa_rpipe' that is
+ * attached to the hcpriv member of a 'struct usb_host_endpoint'.
+ *
+ * When you need to xfer data to an endpoint, you get an rpipe for it
+ * with wa_ep_rpipe_get(), which gives you a reference to the rpipe
+ * and keeps a single one (the first one) with the endpoint. When you
+ * are done transferring, you drop that reference. At the end the
+ * rpipe is always allocated and bound to the endpoint. There it might
+ * be recycled when not used.
+ *
+ * Addresses:
+ *
+ *  We use a 1:1 mapping mechanism between port address (0 based
+ *  index, actually) and the address. The USB stack knows about this.
+ *
+ *  USB Stack port number    4 (1 based)
+ *  WUSB code port index     3 (0 based)
+ *  USB Addresss             5 (2 based -- 0 is for default, 1 for root hub)
+ *
+ *  Now, because we don't use the concept as default address exactly
+ *  like the (wired) USB code does, we need to kind of skip it. So we
+ *  never take addresses from the urb->pipe, but from the

+ * size is a multiple of the maxpacket size). For each segment issue a
+ * segment request (struct wa_xfer_*), then send the data buffer if
+ * out or nothing if in (all over the DTO endpoint).
+ *
+ * For each submitted segment request, a notification will come over
+ * the NEP endpoint and a transfer result (struct xfer_result) will
+ * arrive in the DTI URB. Read it, get the xfer ID, see if there is
+ * data coming (inbound transfer), schedule a read and handle it.
+ *
+ * Sounds simple, it is a pain to implement.

+ * LIFE CYCLE / STATE DIAGRAM
+ *
+ *   FIXME
+ *
+ * THIS CODE IS DISGUSTING
+ *
+ *   Warned you are; it's my second try and still not happy with it.
+ *
+ * NOTES:
+ *
+ *   - No iso
+ *
+ *   - Supports DMA xfers, control, bulk and maybe interrupt
+ *
+ *   - Does not recycle unused rpipes
+ *
+ *     An rpipe is assigned to an endpoint the first time it is used,
+ *     and then it's there, assigned, until the endpoint is disabled
+ *     (destroyed [{h,d}wahc_op_ep_disable()]. The assignment of the
+ *     rpipe to the endpoint is done under the wa->rpipe_sem semaphore
+ *     (should be a mutex).
+ *
+ *     Two methods it could be done:
+ *
+ *     (a) set up a timer everytime an rpipe's use count drops to 1
+ *         (which means unused) or when a transfer ends. Reset the
+ *         timer when a xfer is queued. If the timer expires, release
+ *         the rpipe [see rpipe_ep_disable()].
+ *
+ *     (b) when looking for free rpipes to attach [rpipe_get_by_ep()],
+ *         when none are found go over the list, check their endpoint
+ *         and their activity record (if no last-xfer-done-ts in the
+ *         last x seconds) take it
+ *
+ *     However, due to the fact that we have a set of limited

+ * functions/operations that only deal with general Wireless USB HC
+ * issues use this data type to refer to the host.
+ *
+ * @usb_hcd 	   Instantiation of a USB host controller
+ *                 (initialized by upper layer [HWA=HC or WHCI].
+ *
+ * @dev		   Device that implements this; initialized by the
+ *                 upper layer (HWA-HC, WHCI...); this device should
+ *                 have a refcount.
+ *
+ * @trust_timeout  After this time without hearing for device
+ *                 activity, we consider the device gone and we have to
+ *                 re-authenticate.
+ *
+ *                 Can be accessed w/o locking--however, read to a
+ *                 local variable then use.
+ *
+ * @chid           WUSB Cluster Host ID: this is supposed to be a
+ *                 unique value that doesn't change across reboots (so
+ *                 that your devices do not require re-association).
+ *
+ *                 Read/Write protected by @mutex
+ *
+ * @dev_info       This array has ports_max elements. It is used to
+ *                 give the HC information about the WUSB devices (see
+ *                 'struct wusb_dev_info').
+ *
+ *	           For HWA we need to allocate it in heap; for WHCI it
+ *                 needs to be permanently mapped, so we keep it for
+ *                 both and make it easy. Call wusbhc->dev_info_set()
+ *                 to update an entry.
+ *
+ * @ports_max	   Number of simultaneous device connections (fake
+ *                 ports) this HC will take. Read-only.
+ *
+ * @port      	   Array of port status for each fake root port. Guaranteed to
+ *                 always be the same lenght during device existence
+ *                 [this allows for some unlocked but referenced reading].
+ *
+ * @mmcies_max	   Max number of Information Elements this HC can send
+ *                 in its MMC. Read-only.
+ *
+ * @mmcie_add	   HC specific operation (WHCI or HWA) for adding an
+ *                 MMCIE.
+ *
+ * @mmcie_rm	   HC specific operation (WHCI or HWA) for removing an
+ *                 MMCIE.
+ *
+ * @enc_types	   Array which describes the encryptions methods
+ *                 supported by the host as described in WUSB1.0 --
+ *                 one entry per supported method. As of WUSB1.0 there
+ *                 is only four methods, we make space for eight just in
+ *                 case they decide to add some more (and pray they do
+ *                 it in sequential order). if 'enc_types[enc_method]
+ *                 != 0', then it is supported by the host. enc_method
+ *                 is USB_ENC_TYPE*.
+ *
+ * @set_ptk:       Set the PTK and enable encryption for a device. Or, if
+ *                 the supplied key is NULL, disable encryption for that
+ *                 device.
+ *
+ * @set_gtk:       Set the GTK to be used for all future broadcast packets
+ *                 (i.e., MMCs).  With some hardware, setting the GTK may start
+ *                 MMC transmission.
+ *
+ * NOTE:
+ *
+ *  - If wusb_dev->usb_dev is not NULL, then usb_dev is valid
+ *    (wusb_dev has a refcount on it). Likewise, if usb_dev->wusb_dev
+ *    is not NULL, usb_dev->wusb_dev is valid (usb_dev keeps a
+ *    refcount on it).
+ *
+ *    Most of the times when you need to use it, it will be non-NULL,
+ *    so there is no real need to check for it (wusb_dev will
+ *    dissapear before usb_dev).
+ *
+ *  - The following fields need to be filled out before calling
+ *    wusbhc_create(): ports_max, mmcies_max, mmcie_{add,rm}.
+ *
+ *  - there is no wusbhc_init() method, we do everything in
+ *    wusbhc_create().
+ *
+ *  - Creation is done in two phases, wusbhc_create() and

+ *    calling usb_hcd_add(&wusbhc->usb_hcd).

+	  UWB is a high-bandwidth, low-power, point-to-point radio
+	  technology using a wide spectrum (3.1-10.6GHz). It is
+	  optimized for in-room use (480Mbps at 2 meters, 110Mbps at
+	  10m). It serves as the transport layer for other protocols,
+	  such as Wireless USB (WUSB), IP (WLP) and upcoming
+	  Bluetooth and 1394
+
+	  The topology is peer to peer; however, higher level
+	  protocols (such as WUSB) might impose a master/slave
+	  relationship.
+
+	  Say Y here if your computer has UWB radio controllers (USB or PCI)
+	  based. You will need to enable the radio controllers
+	  below.  It is ok to select all of them, no harm done.
+
+	  For more help check the UWB and WUSB related files in
+	  <file:Documentation/usb/>.

+ * i1480u's RX handling is simple. i1480u will send the received
+ * network packets broken up in fragments; 1 to N fragments make a
+ * packet, we assemble them together and deliver the packet with netif_rx().
+ *
+ * Beacuse each USB transfer is a *single* fragment (except when the
+ * transfer contains a first fragment), each URB called thus
+ * back contains one or two fragments. So we queue N URBs, each with its own
+ * fragment buffer. When a URB is done, we process it (adding to the
+ * current skb from the fragment buffer until complete). Once
+ * processed, we requeue the URB. There is always a bunch of URBs
+ * ready to take data, so the intergap should be minimal.
+ *
+ * An URB's transfer buffer is the data field of a socket buffer. This
+ * reduces copying as data can be passed directly to network layer. If a
+ * complete packet or 1st fragment is received the URB's transfer buffer is
+ * taken away from it and used to send data to the network layer. In this
+ * case a new transfer buffer is allocated to the URB before being requeued.
+ * If a "NEXT" or "LAST" fragment is received, the fragment contents is
+ * appended to the RX packet under construction and the transfer buffer
+ * is reused. To be able to use this buffer to assemble complete packets
+ * we set each buffer's size to that of the MAX ethernet packet that can
+ * be received. There is thus room for improvement in memory usage.
+ *
+ * When the max tx fragment size increases, we should be able to read
+ * data into the skbs directly with very simple code.

+ *    of a packet).
+ *    Looks like a transfer can contain more than one fragment (07/18/06)
+ *
+ *  - Each transfer buffer is the size of the maximum packet size (minus
+ *    headroom), i1480u_MAX_PKT_SIZE - 2
+ *
+ *  - We always read the full USB-transfer, no partials.
+ *
+ *  - Each transfer is read directly into a skb. This skb will be used to
+ *    send data to the upper layers if it is the first fragment or a complete
+ *    packet. In the other cases the data will be copied from the skb to
+ *    another skb that is being prepared for the upper layers from a prev
+ *    first fragment.
+ *
+ * It is simply too much of a pain. Gosh, there should be a unified
+ * SG infrastructure for *everything* [so that I could declare a SG
+ * buffer, pass it to USB for receiving, append some space to it if
+ * I wish, receive more until I have the whole chunk, adapt
+ * pointers on each fragment to remove hardware headers and then

+ *
+ *
+ * The RC interface of the Host Wire Adapter (USB dongle) or WHCI PCI
+ * card delivers a stream of notifications and events to the
+ * notification end event endpoint or area. This code takes care of
+ * getting a buffer with that data, breaking it up in separate
+ * notifications and events and then deliver those.
+ *
+ * Events are answers to commands and they carry a context ID that
+ * associates them to the command. Notifications are that,
+ * notifications, they come out of the blue and have a context ID of
+ * zero. Think of the context ID kind of like a handler. The
+ * uwb_rc_neh_* code deals with managing context IDs.
+ *
+ * This is why you require a handle to operate on a UWB host. When you
+ * open a handle a context ID is assigned to you.
+ *
+ * So, as it is done is:
+ *
+ * 1. Add an event handler [uwb_rc_neh_add()] (assigns a ctx id)
+ * 2. Issue command [rc->cmd(rc, ...)]
+ * 3. Arm the timeout timer [uwb_rc_neh_arm()]
+ * 4, Release the reference to the neh [uwb_rc_neh_put()]
+ * 5. Wait for the callback
+ * 6. Command result (RCEB) is passed to the callback
+ *
+ * If (2) fails, you should remove the handle [uwb_rc_neh_rm()]
+ * instead of arming the timer.
+ *
+ * Handles are for using in *serialized* code, single thread.
+ *
+ * When the notification/event comes, the IRQ handler/endpoint
+ * callback passes the data read to uwb_rc_neh_grok() which will break
+ * it up in a discrete series of events, look up who is listening for
+ * them and execute the pertinent callbacks.
+ *
+ * If the reader detects an error while reading the data stream, call
+ * uwb_rc_neh_error().
+ *
+ * CONSTRAINTS/ASSUMPTIONS:
+ *
+ * - Most notifications/events are small (less thank .5k), copying
+ *   around is ok.
+ *
+ * - Notifications/events are ALWAYS smaller than PAGE_SIZE
+ *
+ * - Notifications/events always come in a single piece (ie: a buffer
+ *   will always contain entire notifications/events).
+ *
+ * - we cannot know in advance how long each event is (because they
+ *   lack a length field in their header--smart move by the standards
+ *   body, btw). So we need a facility to get the event size given the
+ *   header. This is what the EST code does (notif/Event Size
+ *   Tables), check nest.c--as well, you can associate the size to
+ *   the handle [w/ neh->extra_size()].
+ *
+ * - Most notifications/events are fixed size; only a few are variable
+ *   size (NEST takes care of that).
+ *
+ * - Listeners of events expect them, so they usually provide a
+ *   buffer, as they know the size. Listeners to notifications don't,
+ *   so we allocate their buffers dynamically.

+ * This daemon takes care of maintaing information that describes the
+ * UWB neighborhood that the radios in this machine can see. It also
+ * keeps a tab of which devices are visible, makes sure each HC sits
+ * on a different channel to avoid interfering, etc.
+ *
+ * Different drivers (radio controller, device, any API in general)
+ * communicate with this daemon through an event queue. Daemon wakes
+ * up, takes a list of events and handles them one by one; handling
+ * function is extracted from a table based on the event's type and
+ * subtype. Events are freed only if the handling function says so.
+ *
+ *   . Lock protecting the event list has to be an spinlock and locked
+ *     with IRQSAVE because it might be called from an interrupt
+ *     context (ie: when events arrive and the notification drops
+ *     down from the ISR).
+ *
+ *   . UWB radio controller drivers queue events to the daemon using
+ *     uwbd_event_queue(). They just get the event, chew it to make it
+ *     look like UWBD likes it and pass it in a buffer allocated with
+ *     uwb_event_alloc().
+ *
+ * EVENTS
+ *
+ * Events have a type, a subtype, a lenght, some other stuff and the
+ * data blob, which depends on the event. The header is 'struct
+ * uwb_event'; for payloads, see 'struct uwbd_evt_*'.
+ *
+ * EVENT HANDLER TABLES
+ *
+ * To find a handling function for an event, the type is used to index
+ * a subtype-table in the type-table. The subtype-table is indexed
+ * with the subtype to get the function that handles the event. Start
+ * with the main type-table 'uwbd_evt_type_handler'.
+ *
+ * DEVICES
+ *
+ * Devices are created when a bunch of beacons have been received and
+ * it is stablished that the device has stable radio presence. CREATED
+ * only, not configured. Devices are ONLY configured when an
+ * Application-Specific IE Probe is receieved, in which the device
+ * declares which Protocol ID it groks. Then the device is CONFIGURED
+ * (and the driver->probe() stuff of the device model is invoked).
+ *
+ * Devices are considered disconnected when a certain number of
+ * beacons are not received in an amount of time.
+ *

+ * We need to be able to map ethernet addresses to device addresses

+ * addresses used in the ETH frames and the device addresses (no, it
+ * would not have been simpler to force as ETH address the MBOA MAC
+ * address...no, not at all :).
+ *
+ * A device has one MBOA MAC address and one device address. It is possible
+ * for a device to have more than one virtual MAC address (although a
+ * virtual address can be the same as the MBOA MAC address). The device
+ * address is guaranteed to be unique among the devices in the extended
+ * beacon group (see ECMA 17.1.1). We thus use the device address as index
+ * to this cache. We do allow searching based on virtual address as this
+ * is how Ethernet frames will be addressed.
+ *
+ * We need to support virtual EUI-48. Although, right now the virtual
+ * EUI-48 will always be the same as the MAC SAP address. The EDA cache
+ * entry thus contains a MAC SAP address as well as the virtual address
+ * (used to map the network stack address to a neighbor). When we move
+ * to support more than one virtual MAC on a host then this organization
+ * will have to change. Perhaps a neighbor has a list of WSSs, each with a
+ * tag and virtual EUI-48.
+ *
+ * On data transmission
+ * it is used to determine if the neighbor is connected and what WSS it
+ * belongs to. With this we know what tag to add to the WLP frame. Storing
+ * the WSS in the EDA cache may be overkill because we only support one
+ * WSS. Hopefully we will support more than one WSS at some point.
+ * On data reception it is used to determine the WSS based on
+ * the tag and address of the transmitting neighbor.

+ *         over the entire transmission.
+ *         If it is a unicast the WSS connection should already be established
+ *         and transmission will be done by the calling function.

+ * @returns: 0 on success no tx : WLP header sucessfully applied to skb buffer,
+ *                                calling function can proceed with tx
+ *           1 on success with tx : WLP will take over transmission of this
+ *                                  frame
+ *           <0 on error
+ *
+ * The network stack (WLP client) is attempting to transmit a frame. We can
+ * only transmit data if a local WSS is at least active (connection will be
+ * done here if this is a broadcast frame and neighbor also has the WSS
+ * active).
+ *
+ * The frame can be either broadcast or unicast. Broadcast in a WSS is
+ * supported via multicast, but we don't support multicast yet (until
+ * devices start to support MAB IEs). If a broadcast frame needs to be
+ * transmitted it is treated as a unicast frame to each neighbor. In this
+ * case the WLP takes over transmission of the skb and returns 1
+ * to the caller to indicate so. Also, in this case, if a neighbor has the
+ * same WSS activated but is not connected then the WSS connection will be
+ * done at this time. The neighbor's virtual address will be learned at
+ * this time.
+ *
+ * The destination address in a unicast frame is the virtual address of the
+ * neighbor. This address only becomes known when a WSS connection is
+ * established. We thus rely on a broadcast frame to trigger the setup of
+ * WSS connections to all neighbors before we are able to send unicast
+ * frames to them. This seems reasonable as IP would usually use ARP first
+ * before any unicast frames are sent.
+ *
+ * If we are already connected to the neighbor (neighbor's virtual address
+ * is known) we just prepare the WLP header and the caller will continue to
+ * send the frame.
+ *
+ * A failure in this function usually indicates something that cannot be
+ * fixed automatically. So, if this function fails (@return < 0) the calling
+ * function should not retry to send the frame as it will very likely keep
+ * failing.

- * The LOCK_PREFIX macro defined here replaces the LOCK and
- * LOCK_PREFIX macros used everywhere in the source tree.
- *
- * SMP alternatives use the same data structures as the other
- * alternatives and the X86_FEATURE_UP flag to indicate the case of a
- * UP system running a SMP kernel.  The existing apply_alternatives()
- * works fine for patching a SMP kernel for UP.
- *
- * The SMP alternative tables can be kept after boot and contain both
- * UP and SMP versions of the instructions to allow switching back to
- * SMP at runtime, when hotplugging in a new CPU, which is especially
- * useful in virtualized environments.
- *
- * The very common lock prefix is handled as special case in a
- * separate table which is a pure address list without replacement ptr
- * and size information.  That keeps the table sizes small.

- * The set_memory_* API can be used to change various attributes of a virtual

- * Read/Write    : ReadOnly, ReadWrite
- * Presence      : NotPresent

- * Within a catagory, the attributes are mutually exclusive.

- * The implementation of this API will take care of various aspects that

- * - Flushing TLBs
- * - Flushing CPU caches
- * - Making sure aliases of the memory behind the mapping don't violate
- *   coherency rules as defined by the CPU in the system.
- *
- * What this API does not do:
- * - Provide exclusion between various callers - including callers that
- *   operation on other mappings of the same physical page
- * - Restore default attributes when a page is freed
- * - Guarantee that mappings other than the requested one are
- *   in any state, other than that these do not violate rules for
- *   the CPU you have. Do not depend on any effects on other mappings,
- *   CPUs other than the one you have may have more relaxed rules.

- * NOTES about DMA transfers:
- *
- *  controller 1: channels 0-3, byte operations, ports 00-1F
- *  controller 2: channels 4-7, word operations, ports C0-DF
- *
- *  - ALL registers are 8 bits only, regardless of transfer size
- *  - channel 4 is not used - cascades 1 into 2.
- *  - channels 0-3 are byte - addresses/counts are for physical bytes
- *  - channels 5-7 are word - addresses/counts are for physical words
- *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
- *  - transfer count loaded to registers is 1 less than actual count
- *  - controller 2 offsets are all even (2x offsets for controller 1)
- *  - page registers for 5-7 don't use data bit 0, represent 128K pages
- *  - page registers for 0-3 use bit 0, represent 64K pages
- *
- * DMA transfers are limited to the lower 16MB of _physical_ memory.
- * Note that addresses loaded into registers must be _physical_ addresses,
- * not logical addresses (which may differ if paging is active).
- *
- *  Address mapping for channels 0-3:
- *
- *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
- *    |  ...  |   |  ... |   |  ... |
- *    |  ...  |   |  ... |   |  ... |
- *    |  ...  |   |  ... |   |  ... |
- *   P7  ...  P0  A7 ... A0  A7 ... A0
- * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
- *
- *  Address mapping for channels 5-7:
- *
- *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
- *    |  ...  |   \   \   ... \  \  \  ... \  \
- *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
- *    |  ...  |     \   \   ... \  \  \  ... \
- *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0
- * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
- *
- * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
- * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
- * the hardware level, so odd-byte transfers aren't possible).
- *
- * Transfer count (_not # bytes_) is limited to 64K, represented as actual
- * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
- * and up to 128K bytes may be transferred on channels 5-7 in one operation.

- * x86_emulate_ops:
- *
- * These operations represent the instruction emulator's interface to memory.
- * There are two categories of operation: those that act on ordinary memory
- * regions (*_std), and those that act on memory regions known to require
- * special treatment or emulation (*_emulated).
- *
- * The emulator assumes that an instruction accesses only one 'emulated memory'
- * location, that this location is the given linear faulting address (cr2), and
- * that this is one of the instruction's data operands. Instruction fetches and
- * stack operations are assumed never to access emulated memory. The emulator
- * automatically deduces which operand of a string-move operation is accessing
- * emulated memory, and assumes that the other operand accesses normal memory.
- *
- * NOTES:
- *  1. The emulator isn't very smart about emulated vs. standard memory.
- *     'Emulated memory' access addresses should be checked for sanity.
- *     'Normal memory' accesses may fault, and the caller must arrange to
- *     detect and handle reentrancy into the emulator via recursive faults.
- *     Accesses may be unaligned and may cross page boundaries.
- *  2. If the access fails (cannot emulate, or a standard access faults) then
- *     it is up to the memop to propagate the fault to the guest VM via
- *     some out-of-band mechanism, unknown to the emulator. The memop signals
- *     failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will
- *     then immediately bail.
- *  3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only
- *     cmpxchg8b_emulated need support 8-byte accesses.
- *  4. The emulator cannot handle 64-bit mode emulation on an x86/32 system.

- * ideally, patch an inline implementation into the callsite.  (Direct
- * calls are essentially free, because the call and return addresses
- * are completely predictable.)
- *
- * For i386, these macros rely on the standard gcc "regparm(3)" calling
- * convention, in which the first three arguments are placed in %eax,
- * %edx, %ecx (in that order), and the remaining arguments are placed
- * on the stack.  All caller-save registers (eax,edx,ecx) are expected
- * to be modified (either clobbered or used for return values).
- * X86_64, on the other hand, already specifies a register-based calling
- * conventions, returning at %rax, with parameteres going on %rdi, %rsi,
- * %rdx, and %rcx. Note that for this reason, x86_64 does not need any
- * special handling for dealing with 4 arguments, unlike i386.
- * However, x86_64 also have to clobber all caller saved registers, which
- * unfortunately, are quite a bit (r8 - r11)
- *
- * The call instruction itself is marked by placing its start address
- * and size into the .parainstructions section, so that
- * apply_paravirt() in arch/i386/kernel/alternative.c can do the
- * appropriate patching under the control of the backend pv_init_ops
- * implementation.
- *
- * Unfortunately there's no way to get gcc to generate the args setup
- * for the call, and then allow the call itself to be generated by an
- * inline asm.  Because of this, we must do the complete arg setup and
- * return value handling from within these macros.  This is fairly
- * cumbersome.
- *
- * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments.
- * It could be extended to more arguments, but there would be little
- * to be gained from that.  For each number of arguments, there are
- * the two VCALL and CALL variants for void and non-void functions.
- *
- * When there is a return value, the invoker of the macro must specify
- * the return type.  The macro then uses sizeof() on that type to
- * determine whether its a 32 or 64 bit value, and places the return
- * in the right register(s) (just %eax for 32-bit, and %edx:%eax for
- * 64-bit). For x86_64 machines, it just returns at %rax regardless of
- * the return value size.
- *
- * 64-bit arguments are passed as a pair of adjacent 32-bit arguments
- * i386 also passes 64-bit arguments as a pair of adjacent 32-bit arguments
- * in low,high order
- *
- * Small structures are passed and returned in registers.  The macro
- * calling convention can't directly deal with this, so the wrapper
- * functions must do this.
- *
- * These PVOP_* macros are only defined within this header.  This
- * means that all uses must be wrapped in inline functions.  This also
- * makes sure the incoming and outgoing types are always correct.

-/* rwsem.h: R/W semaphores implemented using XADD/CMPXCHG for i486+
- *
- * Written by David Howells (dhowells@redhat.com).
- *
- * Derived from asm-x86/semaphore.h
- *
- *
- * The MSW of the count is the negated number of active writers and waiting
- * lockers, and the LSW is the total number of active locks
- *
- * The lock count is initialized to 0 (no active and no waiting lockers).
- *
- * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an
- * uncontended lock. This can be determined because XADD returns the old value.
- * Readers increment by 1 and see a positive value when uncontended, negative
- * if there are writers (and maybe) readers waiting (in which case it goes to
- * sleep).
- *
- * The value of WAITING_BIAS supports up to 32766 waiting processes. This can
- * be extended to 65534 by manually checking the whole MSW rather than relying
- * on the S flag.
- *
- * The value of ACTIVE_BIAS supports up to 65535 active processes.
- *
- * This should be totally fair - if anything is waiting, a process that wants a
- * lock will go to the back of the queue. When the currently active lock is
- * released, if there's a writer at the front of the queue, then that and only
- * that will be woken up; if there's a bunch of consequtive readers at the
- * front, then they'll all be woken up, but no other readers will be.

- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier.  All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads.  This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies.  See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	b = 2;
- *	memory_barrier();
- *	p = &b;				q = p;
- *					read_barrier_depends();
- *					d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends().  However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	a = 2;
- *	memory_barrier();
- *	b = 3;				y = b;
- *					read_barrier_depends();
- *					x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b".  Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
- * in cases like this where there are no data dependencies.

-   contents of them.  Actually, you can read in the core file and look at
-   the contents of the user struct to find out what the floating point

-   The actual file contents are as follows:
-   UPAGE: 1 page consisting of a user struct that tells gdb what is present

-   is currently not used by gdb, but it may come in useful at some point.
-   All of the registers are stored as part of the upage.  The upage should
-   always be only one page.
-   DATA: The data area is stored.  We use current->end_text to
-   current->brk to pick up all of the user variables, plus any memory
-   that may have been malloced.  No attempt is made to determine if a page
-   is demand-zero or if a page is totally unused, we just cover the entire
-   range.  All of the addresses are rounded in such a way that an integral
-   number of pages is written.
-   STACK: We need the stack information in order to get a meaningful
-   backtrace.  We need to write the data from (esp) to
-   current->start_stack, so we round each of these off in order to be able
-   to write an integer number of pages.

-   DATA: The data area is stored.  We use current->end_text to
-   current->brk to pick up all of the user variables, plus any memory
-   that may have been malloced.  No attempt is made to determine if a page
-   is demand-zero or if a page is totally unused, we just cover the entire
-   range.  All of the addresses are rounded in such a way that an integral
-   number of pages is written.
-   STACK: We need the stack information in order to get a meaningful
-   backtrace.  We need to write the data from (esp) to
-   current->start_stack, so we round each of these off in order to be able
-   to write an integer number of pages.
-   The minimum core file size is 3 pages, or 12288 bytes.  */

- * Addressing Terminology
- *
- *	M       - The low M bits of a physical address represent the offset
- *		  into the blade local memory. RAM memory on a blade is physically
- *		  contiguous (although various IO spaces may punch holes in
- *		  it)..
- *
- * 	N	- Number of bits in the node portion of a socket physical
- * 		  address.
- *
- * 	NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
- * 	 	  routers always have low bit of 1, C/MBricks have low bit
- * 		  equal to 0. Most addressing macros that target UV hub chips
- * 		  right shift the NASID by 1 to exclude the always-zero bit.
- * 		  NASIDs contain up to 15 bits.
- *
- *	GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
- *		  of nasids.
- *
- * 	PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
- * 		  of the nasid for socket usage.
- *
- *
- *  NumaLink Global Physical Address Format:
- *  +--------------------------------+---------------------+

- * The hypercall asms have to meet several constraints:
- * - Work on 32- and 64-bit.
- *    The two architectures put their arguments in different sets of
- *    registers.
- *
- * - Work around asm syntax quirks
- *    It isn't possible to specify one of the rNN registers in a
- *    constraint, so we use explicit register variables to get the
- *    args into the right place.
- *
- * - Mark all registers as potentially clobbered
- *    Even unused parameters can be clobbered by the hypervisor, so we
- *    need to make sure gcc knows it.
- *
- * - Avoid compiler bugs.
- *    This is the tricky part.  Because x86_32 has such a constrained
- *    register set, gcc versions below 4.3 have trouble generating
- *    code when all the arg registers and memory are trashed by the
- *    asm.  There are syntactically simpler ways of achieving the
- *    semantics below, but they cause the compiler to crash.
- *
- *    The only combination I found which works is:
- *     - assign the __argX variables first
- *     - list all actually used parameters as "+r" (__argX)
- *     - clobber the rest
- *
- * The result certainly isn't pretty, and it really shows up cpp's
- * weakness as as macro language.  Sorry.  (But let's just give thanks
- * there aren't more than 5 arguments...)

- *  2. If the MFN belongs to a different domain then we will certainly
- *     not have MFN in our p2m table. Conversely, if the page is ours,
- *     then we'll have p2m(m2p(MFN))==MFN.
- * If we detect a special mapping then it doesn't have a 'struct page'.
- * We force !pfn_valid() by returning an out-of-range pointer.
- *
- * NB. These checks require that, for any MFN that is not in our reservation,
- * there is no PFN such that p2m(PFN) == MFN. Otherwise we can get confused if
- * we are foreign-mapping the MFN, and the other domain as m2p(MFN) == PFN.
- * Yikes! Various places must poke in INVALID_P2M_ENTRY for safety.
- *
- * NB2. When deliberately mapping foreign pages into the p2m table, you *must*
- *      use FOREIGN_FRAME(). This will cause pte_pfn() to choke on it, as we
- *      require. In all the cases we care about, the FOREIGN_FRAME bit is
- *      masked (e.g., pfn_to_mfn()) so behaviour there is correct.

+ * UWB radio controller Event Size Entry (for creating entry tables)

+ *
+ * Each event/notification has a size which is not necessarily known
+ * in advance based on the event code. As well, vendor specific
+ * events/notifications will have a size impossible to determine
+ * unless we know about the device's specific details.
+ *
+ * It was way too smart of the spec writers not to think that it would
+ * be impossible for a generic driver to skip over vendor specific
+ * events/notifications if there are no LENGTH fields in the HEADER of
+ * each message...the transaction size cannot be counted on as the
+ * spec does not forbid to pack more than one event in a single
+ * transaction.
+ *
+ * Thus, we guess sizes with tables (or for events, when you know the
+ * size ahead of time you can use uwb_rc_neh_extra_size*()). We
+ * register tables with the known events and their sizes, and then we
+ * traverse those tables. For those with variable length, we provide a
+ * way to lookup the size inside the event/notification's
+ * payload. This allows device-specific event size tables to be
+ * registered.
+ *
+ * @size:   Size of the payload

+ * UMC (UWB Multi-interface Controller) capabilities (e.g., radio
+ * controller, host controller) are presented as devices on the "umc"
+ * bus.
+ *
+ * The radio controller is not strictly a UMC capability but it's

+ *
+ * References:
+ *
+ *   [WHCI] Wireless Host Controller Interface Specification for
+ *          Certified Wireless Universal Serial Bus, revision 0.95.
+ *
+ * How this works is kind of convoluted but simple. The whci.ko driver
+ * loads when WHCI devices are detected. These WHCI devices expose
+ * many devices in the same PCI function (they couldn't have reused
+ * functions, no), so for each PCI function that exposes these many
+ * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
+ * with umc_device_create() and adds it to the bus with
+ * umc_device_register().
+ *
+ * umc_device_register() calls device_register() which will push the
+ * bus management code to load your UMC driver's somehting_probe()
+ * that you have registered for that capability code.
+ *
+ * Now when the WHCI device is removed, whci_remove() will go over
+ * each umc_dev assigned to each of the PCI function's capabilities
+ * and through whci_del_cap() call umc_device_unregister() each
+ * created umc_dev. Of course, if you are bound to the device, your
+ * driver's something_remove() will be called.
