* gpu: nvgpu: gr faults: do not depend on fake mmu fault notifierSeema Khowala2017-03-23
| | | | | | | | | | | | | | | | | | | | Currently NVGPU_CHANNEL_FIFO_ERROR_MMU_ERR_FLT is being set in error notifier for non mmu fault too. For fake mmu faults i.e. trigger mmu fault cases, make sure proper notifiers are set and driver is not depending on sending mmu error fault notifier. This change is needed for t19x fifo recovery too. NVGPU_CHANNEL_GR_ERROR_SW_METHOD (12), NVGPU_CHANNEL_GR_EXCEPTION(13) and NVGPU_CHANNEL_FECS_ERR_UNIMP_FIRMWARE_METHOD (37) are new error notifiers.

| | | | | | | | | | | | | | | | | | | | | Move all programming of FB to fb_*.c files, and remove the inclusion of FB hardware headers from other files. TLB invalidate function took previously a pointer to VM, but the new API takes only a PDB mem_desc, because FB does not need to know about higher level VM. GPC MMU is programmed from the same function as FB MMU, so added dependency to GR hardware header to FB. GP106 ACR was also triggering a VPR fetch, but that's not applicable to dGPU, so removed that call.

* gpu: nvgpu: add worker for watchdog and job cleanupKonsta Holtta2017-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a worker thread to replace the delayed works in channel watchdog and job cleanups. Watchdog runs by polling the channel states periodically, and job cleanup is performed on channels that are appended on a work queue consumed by the worker thread. Handling both of these two in the same thread makes it impossible for them to cause a deadlock, as has previously happened. The watchdog takes references to channels during checking and possibly recovering channels. Jobs in the cleanup queue have an additional reference taken which is released after the channel is processed. The worker is woken up from periodic sleep when channels are added to the queue. Currently, the queue is only used for job cleanups, but it is extendable for other per-channel works too. The worker can also process other periodic actions dependent on channels. Neither the semantics of timeout handling or of job cleanups are yet significantly changed - this patch only serializes them into one background thread. Each job that needs cleanup is tracked and holds a reference to its channel and a power reference, and timeouts can only be processed on channels that are tracked, so the thread will always be idle if the system is going to be suspended, so there is currently no need to explicitly suspend or stop it.

Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu and rename it to semaphore.h. Also update all places where the header is inluced to use the new path. This revealed an odd location for the enum gk20a_mem_rw_flag. This should be in the mm headers. As a result many places that did not need anything semaphore related had to include the semaphore header file. Fixing this oddity allowed the semaphore include to be removed from many C files that did not need it.

Because all of the buffers haven't been tested to work in vidmem yet, rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at the end to declare explicitly that vidmem is used. Enabling vidmem for each now is a matter of removing "_sys" from the function call.
