drm/amdgpu: Avoid reclaim fs while eviction lock

2020-01-16T18:33:16Z

[Why] Avoid reclaim filesystem while eviction lock is held called from MMU notifier. [How] Setting PF_MEMALLOC_NOFS flags while eviction mutex is locked. Using memalloc_nofs_save / memalloc_nofs_restore API. Signed-off-by: Alex Sierra Reviewed-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: replace vm_pte's run-queue list with drm gpu scheds list

2019-12-18T21:09:12Z

drm_sched_entity_init() takes drm gpu scheduler list instead of drm_sched_rq list. This makes conversion of drm_sched_rq list to drm gpu scheduler list unnecessary Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/scheduler: rework entity creation

2019-12-18T21:09:12Z

Entity currently keeps a copy of run_queue list and modify it in drm_sched_entity_set_priority(). Entities shouldn't modify run_queue list. Use drm_gpu_scheduler list instead of drm_sched_rq list in drm_sched_entity struct. In this way we can select a runqueue based on entity/ctx's priority for a drm scheduler.

drm/amdgpu: add VM eviction lock v3

2019-12-09T22:02:26Z

This allows to invalidate VM entries without taking the reservation lock. v3: use -EBUSY Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: stop adding VM updates fences to the resv obj

2019-12-09T22:02:15Z

Don't add the VM update fences to the resv object and remove the handling to stop implicitely syncing to them. Ongoing updates prevent page tables from being evicted and we manually block for all updates to complete before releasing PDs and PTS. This way we can do updates even without the resv obj locked.

drm/amdgpu: move VM eviction decision into amdgpu_vm.c

2019-12-09T22:01:51Z

When a page tables needs to be evicted the VM code should decide if that is possible or not. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

amd/amdgpu: force to trigger a no-retry-fault after a retry-fault

2019-11-22T19:20:23Z

Only for the debugger use case. [why] Avoid endless translation retries, after an invalid address access has been issued to the GPU. Instead, the trap handler is forced to enter by generating a no-retry-fault. A s_trap instruction is inserted in the debugger case to let the wave to enter trap handler to save context. [how] Intentionally using an invalid flag combination (F and P set at the same time) to trigger a no-retry-fault, after a retry-fault happens. This is only valid under compute context.
