The bulk of the additions are for the "cxl" driver, for IBM's Coherent Accelerator Processor Interface (CAPI). Most of it's in drivers/misc, which Greg & Arnd maintain, Greg said he was happy for us to take it through our tree. There's the usual minor cleanups and fixes, including a bit of noise in drivers from some of those. A bunch of updates to our EEH code, which has been getting more testing.

| * | cxl: Fix afu_read() not doing finish_wait() on signal or non-blockingIan Munsie2014-10-091-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If afu_read() returned due to a signal or the AFU file descriptor being opened non-blocking it would not call finish_wait() before returning, which could lead to a crash later when something else wakes up the wait queue. This patch restructures the wait logic to ensure that the cleanup is done correctly. Signed-off-by: Ian Munsie <imunsie@au1.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

| * | cxl: Driver code for powernv PCIe based cards for userspace accessIan Munsie2014-10-0810-0/+4453
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the core of the cxl driver. It adds support for using cxl cards in the powernv environment only (ie POWER8 bare metal). It allows access to cxl accelerators by userspace using the /dev/cxl/afuM.N char devices. The kernel driver has no knowledge of the function implemented by the accelerator. It provides services to userspace via the /dev/cxl/afuM.N devices. When a program opens this device and runs the start work IOCTL, the accelerator will have coherent access to that processes memory using the same virtual addresses. That process may mmap the device to access any MMIO space the accelerator provides. Also, reads on the device will allow interrupts to be received. These services are further documented in a later patch in Documentation/powerpc/cxl.txt. Documentation of the cxl hardware architecture and userspace API is provided in subsequent patches.

| * | cxl: Add base builtin supportIan Munsie2014-10-085-0/+97
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the base cxl support that cannot be built as a module. Specifically it adds the cxl callbacks that are called from the core powerpc mm code which must always exist irrespective of if the cxl module is loaded or not. This is similar to how cell works with CONFIG_SPU_BASE. This adds a cxl_slbia() call (similar to spu_flush_all_slbs()) which checks if the cxl module is loaded and in use, returning immediately if it is not. If it is in use it calls into the cxl SLB invalidation code.

Otherwise, a segmentation may happen when kexec-ing a new kernel (see backtrace below). An interruption may happen before the handler is set, leading to a kernel segmentation fault. Furthermore, we make sure the interruptions are masked when the driver is initialized. This will prevent freshly kexec-ed kernel from crashing when launched from a kernel which does not properly mask interruptions at shutdown. The backtrace below happened after kexec-ing a new kernel, from a kernel that did not shut down properly leaving interruptions unmasked.

Moreover, resources retrieval are usually done in the probe function, thus moving them add some consistency with other drivers. Initialization is done once, ie not every time a tc block is requested. If it fails, the device is not appended to the list of tc blocks. Furhermore, the device id is retrieved at probe as well, avoiding parsing DT every time the user requests of tc block.

This caused polling by applications which increased the load on the already busy system. This change implements the possiblity to sleep on a waitqueue instead when the DDCB queue is busy. The requestor is woken up when there is free space on the queue again. The old way to get -EBUSY is still available if the device is openend with O_NONBLOCKING. The default is now blocking behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow up patch to the one from Sebastian Ott. There is no need to change the return code once it fails. And Sebastians version is tested now and works nicely on our test-system. Signed-off-by: Frank Haverkamp <haver@linux.vnet.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| * | | | GenWQE: Remove sysfs entry for driver versionFrank Haverkamp2014-09-245-13/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A special sysfs entry to display the driver version is not needed. We left the driver version and adjusted it to the naming a lot of other drivers use. The information can be retrieved by using modinfo genwqe_card. modinfo genwqe_card will provide the same information.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver is using the pci_get_totalvfs() return code directly in a loop. To avoid problems with potentially negative returns in case of errors, we are adding some more sanity checking code.

This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function. Also, the unnecessary labels are removed and linux/device.h is added to make sure the devm_*() routine declarations are unambiguously available. The initial call to platform_get_resource is moved down to the introduced call to devm_ioremap_resource that uses its result.

Also, a label and the err variable are removed. The header device.h is included to make the devm_ function explicitly available and slab.h is done away with as it is no longer needed.
