drm/amdgpu: Switch to interruptable wait to recover from ring hang.

2018-05-09T20:16:51Z

v2: Use dma_fence_wait instead of dma_fence_wait_timeout(...,MAX_SCHEDULE_TIMEOUT) Avoid printing error message for ERESTARTSYS Originally-by: David Panariti Signed-off-by: Andrey Grodzovsky Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56Z

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

drm/amdgpu:implement ctx query2

drm/amdgpu:don't change ctx->reset_couner upon query

2017-12-04T21:33:11Z

reset_counter marks the reset counter number once the context is created, shouldn't be changed due to query. To keep U/K interface on the ctx_query and keep ctx's reset_counter logic compatible with GPU RESET feature, now use another var named "reset_counter_query" to replace the original checked & updated in amdgpu_ctx_query.

drm/amdgpu:pass ctx->guilty address to entity init

2017-12-04T21:33:09Z

this way the real interested guilty is connected to entity->guilty pointer, and we can use entity->pointer later in gpu recovery procedure Signed-off-by: Monk Liu Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher

drm/amd/scheduler:introduce guilty pointer member

2017-12-04T21:33:09Z

this member will be used later, it will points to the real var inside of context and CS_SUBMIT & gpu schdduler can decide if skip a job depends on context->guilty or *entity->guilty Signed-off-by: Monk Liu Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher

drm/amdgpu: move the VRAM lost counter per context

drm/amdgpu: Move old fence waiting before reservation lock is aquired v2

2017-10-19T19:26:59Z

Helps avoiding deadlock during GPU reset. Added mutex to amdgpu_ctx to preserve order of fences on a ring. v2: Put waiting logic in a function in a seperate function in amdgpu_ctx.c Signed-off-by: Andrey Grodzovsky Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: add interface for editing a foreign process's priority v3

2017-10-09T20:30:24Z

The AMDGPU_SCHED_OP_PROCESS_PRIORITY_OVERRIDE ioctls are used to set the priority of a different process in the current system. When a request is dropped, the process's contexts will be restored to the priority specified at context creation time. A request can be dropped by setting the override priority to AMDGPU_CTX_PRIORITY_UNSET. An fd is used to identify the remote process. This is simpler than passing a pid number, which is vulnerable to re-use, etc. This functionality is limited to DRM_MASTER since abuse of this interface can have a negative impact on the system's performance. v2: removed unused output structure v3: change refcounted interface for a regular set operation Signed-off-by: Andres Rodriguez Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: add plumbing for ctx priority changes v2

2017-10-09T20:30:24Z

Introduce amdgpu_ctx_priority_override(). A mechanism to override a context's priority. An override can be terminated by setting the override to AMD_SCHED_PRIORITY_UNSET. v2: change refcounted interface for a direct set Signed-off-by: Andres Rodriguez Acked-by: Christian König Signed-off-by: Alex Deucher
