drm/amdgpu: Add command to override the context priority.

2019-02-15T16:15:43Z

Given a master fd we can then override the priority of the context in another fd. Using these overrides was recommended by Christian instead of trying to submit from a master fd, and I am adding a way to override a single context instead of the entire process so we can only upgrade a single Vulkan queue and not effectively the entire process. Reused the flags field as it was checked to be 0 anyways, so nothing used it. This is source-incompatible (due to the name change), but ABI compatible.

drm/amdgpu: Check if fd really is an amdgpu fd.

2019-02-15T16:15:37Z

Otherwise we interpret the file private data as drm & amdgpu data while it might not be, possibly allowing one to get memory corruption. Signed-off-by: Bas Nieuwenhuizen Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix incorrect use of drm_file->pid

2018-08-21T19:19:18Z

That's the PID of the creator of the file (usually the X server) and not the end user of the file. Signed-off-by: Christian König Acked-by: Alex Deucher Signed-off-by: Alex Deucher CC: stable@vger.kernel.org

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.

Don't leak implementation details about how each priority behaves to usermode. This allows greater flexibility in the future. Squash into c2636dc53abd8269a0930bccd564f2f195dba729 Signed-off-by: Andres Rodriguez 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
