2011-12-21cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystemKay Sievers3-139/+137
This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem and converts the devices to regular devices. The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.

This patch add support for calling ctrl_alt_del() when the power button is pressed for more than about 2 seconds on some freescale MPC83xx evaluation boards and reference design. The code uses a kthread to poll the CTRL_BTN bit each second. Also change Kconfig entry of the driver to bool, as device's gpio registration is broken when loading as module.

2011-10-31powerpc: remove non-required uses of include <linux/module.h>Paul Gortmaker19-21/+0
None of the files touched here are modules, and they are not exporting any symbols either -- so there is no need to be including the module.h. Builds of all the files remains successful. Even kernel/module.c does not need to include it, since it includes linux/moduleloader.h instead. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31powerpc: various straight conversions from module.h --> export.hPaul Gortmaker23-23/+23

2011-10-31powerpc: convert hvconsole.c to export.h ; fix implicit use of errno.hPaul Gortmaker1-1/+2
This file is only exporting symbols and so should use export.h and not module.h header. But in doing the conversion, we will uncover that it was implicitly using errno.h via module.h: CC arch/powerpc/platforms/pseries/hvconsole.o arch/powerpc/platforms/pseries/hvconsole.c: In function 'hvc_put_chars': arch/powerpc/platforms/pseries/hvconsole.c:77: error: 'EIO' undeclared (first use in this function) Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31powerpc: fix two implicit header uses in pseries/plpar_wrappers.hPaul Gortmaker1-0/+3

2011-10-13powerpc/85xx: Setup secondary cores PIR with hard SMP idKumar Gala1-4/+5
Normally logical and hard cpu ID are the same, however in same cases like on the P3060 they may differ. Where the logical is 0..5, the hard id goes 0,1,4..7. This can causes issues for places we utilize PIR to index into array like in debug exception handlers for finding the exception stack.

2011-10-11powerpc/85xx: clean up FPGA device tree nodes for Freecsale QorIQ boardsTimur Tabi1-4/+7
Standarize and document the FPGA nodes used on Freescale QorIQ reference boards. There are different kinds of FPGAs used on the boards, but only two are currently standard: "pixis", "ngpixis", and "qixis". Although there are minor differences among the boards that have one kind of FPGA, most of the functionality is the same, so it makes sense to create common compatibility strings. We also need to update the P1022DS platform file, because the compatible string for its PIXIS node has changed. This means that older kernels are not compatible with newer device trees. This is not a real problem, however, since that particular function doesn't work anyway. When the DIU is active, the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped device.

Therefore, there's no point in keeping a global variable that indicates which mode we're supposed to use.

2011-09-29powerpc: Fix device-tree matching for Apple U4 bridgeBenjamin Herrenschmidt1-0/+14
Apple Quad G5 has some oddity in it's device-tree which causes the new generic matching code to fail to relate nodes for PCI-E devices below U4 with their respective struct pci_dev. This breaks graphics on those machines among others. This fixes it using a quirk which copies the node pointer from the host bridge for the root complex, which makes the generic code work for the children afterward.

2011-09-23gpio: move mpc8xxx/512x gpio driver to drivers/gpioWolfram Sang5-17/+16
Move the driver to the place where it is expected to be nowadays. Also rename its CONFIG-name to match the rest and adapt the defconfigs. Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to the platforms, because this option is per-platform and not per-driver.

2011-09-20powerpc/powernv: Handle PCI-X/PCIe reset delayBenjamin Herrenschmidt1-0/+32
The firmware doesn't wait after lifting the PCI reset. However it does timestamp it in the device tree. We use that to ensure we wait long enough (3s is our current arbitrary setting) from that timestamp to actually probing the bus. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Implement MSI support for p5ioc2 PCIeBenjamin Herrenschmidt3-0/+168
This implements support for MSIs on p5ioc2 PHBs. We only support MSIs on the PCIe PHBs, not the PCI-X ones as the later hasn't been properly verified in HW. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Add support for p5ioc2 PCI-X and PCIeBenjamin Herrenschmidt6-1/+518
This adds support for PCI-X and PCIe on the p5ioc2 IO hub using OPAL. This includes allocating & setting up TCE tables and config space access routines. This also supports fallbacks via RTAS when OPAL is absent, using legacy TCE format pre-allocated via the device-tree (BML style) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Machine check and other system interruptsBenjamin Herrenschmidt2-0/+131
OPAL can handle various interrupt for us such as Machine Checks (it performs all sorts of recovery tasks and passes back control to us with informations about the error), Hardware Management Interrupts and Softpatch interrupts. This wires up the mechanisms and prints out specific informations returned by HAL when a machine check occurs. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Register and handle OPAL interruptsBenjamin Herrenschmidt1-0/+31
We do the minimum which is to "pass" interrupts to HAL, which makes the console smoother and will allow us to implement interrupt based completion and console. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Add RTC and NVRAM support plus RTAS fallbacksBenjamin Herrenschmidt4-21/+223
Implements OPAL RTC and NVRAM support and wire all that up to the powernv platform. We use RTAS for RTC as a fallback if available. Using RTAS for nvram is not supported yet, pending some rework/cleanup and generalization of the pSeries & CHRP code. We also use RTAS fallbacks for power off and reboot Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Hookup reboot and poweroff functionsBenjamin Herrenschmidt1-6/+26
This calls the respective HAL functions, and spin on hal_poll_event() to ensure the HAL has a chance to communicate with the FSP to trigger the reboot or shutdown operation Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-09-20powerpc/powernv: Support for OPAL consoleBenjamin Herrenschmidt2-19/+26
This adds a udbg and an hvc console backend for supporting a console using the OPAL console interfaces. On OPAL v1 we have hvc0 mapped to whatever console the system was configured for (network or hvsi serial port) via the service processor. On OPAL v2 we have hvcN mapped to the Nth console provided by OPAL which generally corresponds to: hvc0 : network console (raw protocol) hvc1 : serial port S1 (hvsi) hvc2 : serial port S2 (hvsi) Note: At this point, early debug console only works with OPAL v1 and shouldn't be enabled in a normal kernel.

2011-09-20powerpc/powernv: Basic support for OPALBenjamin Herrenschmidt6-4/+293

2011-09-20powerpc/powernv: Add OPAL takeover from PowerVMBenjamin Herrenschmidt2-1/+141
On machines supporting the OPAL firmware version 1, the system is initially booted under pHyp. We then use a special hypercall to verify if OPAL is available and if it is, we then trigger a "takeover" which disables pHyp and loads the OPAL runtime firmware, giving control to the kernel in hypervisor mode. This patch add the necessary code to detect that the OPAL takeover capability is present when running under PowerVM (aka pHyp) and perform said takeover to get hypervisor control of the processor. To perform the takeover, we must first use RTAS (within Open Firmware runtime environment) to start all processors & threads, in order to give control to OPAL on all of them. We then call the takeover hypercall on everybody, OPAL will re-enter the kernel main entry point passing it a flat device-tree. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2011-09-20powerpc: Add skeleton PowerNV platformBenjamin Herrenschmidt7-0/+261
This adds a skeletton for the new Power "Non Virtualized" platform which will be used by machines supporting running without an hypervisor, for example in order to run KVM. These machines will be using a new firmware called OPAL for which the support will be provided by later patches. The PowerNV platform is intended to be also usable under the BML environment used internally for early CPU bringup which is why the code also supports using RTAS instead of OPAL in various places.

Since commit 188917e183cf9ad0374b571006d0fc6d48a7f447, /proc/ppc64 is a symlink to /proc/powerpc/. That means that creating /proc/ppc64/eeh will end up with a unaccessible file, that is not listed under /proc/powerpc/ and, then, not listed under /proc/ppc64/. Creating /proc/powerpc/eeh fixes that problem and maintain the compatibility intended with the ppc64 symlink.
