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: 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
