2024-09-07drm/amdgpu: revert "use CPU for page table update if SDMA is unavailable"Christian König1-6/+0
That is clearly not something we should do upstream. The SDMA is mandatory for the driver to work correctly. We could do this for emulation and bringup, but in those cases the engineer should probably enabled CPU based updates manually. This reverts commit 62eefd10ac1c7e976bda47ff311bd87cee40ab8d.

2024-09-07drm/amdgpu: Replace 'amdgpu_job_submit_direct' with 'drm_sched_entity' in ↵Srinivasan Shanmugam1-16/+19
cleaner shader This commit replaces the use of amdgpu_job_submit_direct which submits the job to the ring directly, with drm_sched_entity in the cleaner shader job submission process. The change allows the GPU scheduler to manage the cleaner shader job. - The job is then submitted to the GPU using the drm_sched_entity_push_job function, which allows the GPU scheduler to manage the job. This change improves the reliability of the cleaner shader job submission process by leveraging the capabilities of the GPU scheduler.

Implement the compute pipe reset, and the driver will fallback to pipe reset when queue reset fails. The pipe reset only deactivates the queue which is scheduled in the pipe, and meanwhile the MEC pipe will be reset to the firmware _start pointer. So, it seems pipe reset will cost more cycles than the queue reset; therefore, the driver tries to recover by doing queue reset first.

2024-08-23drm/amdkfd: Change kfd/svm page fault drain handlingXiaogang Chen4-6/+7
When app unmap vm ranges(munmap) kfd/svm starts drain pending page fault and not handle any incoming pages fault of this process until a deferred work item got executed by default system wq. The time period of "not handle page fault" can be long and is unpredicable. That is advese to kfd performance on page faults recovery. This patch uses time stamp of incoming page fault to decide to drop or recover page fault. When app unmap vm ranges kfd records each gpu device's ih ring current time stamp. These time stamps are used at kfd page fault recovery routine. Any page fault happened on unmapped ranges after unmap events is application bug that accesses vm range after unmap. It is not driver work to cover that. By using time stamp of page fault do not need drain page faults at deferred work. So, the time period that kfd does not handle page faults is reduced and can be controlled.
