drm/amdgpu: rework context priority handling

2021-09-01T20:55:11+00:00

To get a hardware queue priority for a context, we are currently mapping AMDGPU_CTX_PRIORITY_* to DRM_SCHED_PRIORITY_* and then to hardware queue priority, which is not the right way to do that as DRM_SCHED_PRIORITY_* is software scheduler's priority and it is independent from a hardware queue priority. Use userspace provided context priority, AMDGPU_CTX_PRIORITY_* to map a context to proper hardware queue priority. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: drm_device to amdgpu_device by inline-f (v2)

2020-08-24T17:06:06+00:00

Get the amdgpu_device from the DRM device by use of an inline function, drm_to_adev(). The inline function resolves a pointer to struct drm_device to a pointer to struct amdgpu_device. v2: Use a typed visible static inline function instead of an invisible macro.

drm/scheduler: Remove priority macro INVALID (v2)

2020-08-18T22:20:26+00:00

Remove DRM_SCHED_PRIORITY_INVALID. We no longer carry around an invalid priority and cut it off at the source. Backwards compatibility behaviour of AMDGPU CTX IOCTL passing in garbage for context priority from user space and then mapping that to DRM_SCHED_PRIORITY_NORMAL is preserved. v2: Revert "res" --> "r" and "prio" --> "priority".

drm/scheduler: Scheduler priority fixes (v2)

2020-08-18T22:20:17+00:00

Remove DRM_SCHED_PRIORITY_LOW, as it was used in only one place. Rename and separate by a line DRM_SCHED_PRIORITY_MAX to DRM_SCHED_PRIORITY_COUNT as it represents a (total) count of said priorities and it is used as such in loops throughout the code. (0-based indexing is the the count number.) Remove redundant word HIGH in priority names, and rename *KERNEL* to *HIGH*, as it really means that, high. v2: Add back KERNEL and remove SW and HW, in lieu of a single HIGH between NORMAL and KERNEL.

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

2019-02-15T16:15:43+00:00

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.

2019-02-15T16:15:37+00:00

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
