drm/amdgpu: Actually check flags for all context ops.

2024-08-29T15:33:16+00:00

commit 0573a1e2ea7e35bff08944a40f1adf2bb35cea61 upstream. Missing validation ... Checked libdrm and it clears all the structs, so we should be safe to just check everything.

drm/amdgpu: Remove redundant call to priority_is_valid()

2023-10-22T00:27:15+00:00

Remove a redundant call to amdgpu_ctx_priority_is_valid() from amdgpu_ctx_priority_permit(), which is called from amdgpu_ctx_init() which is called from amdgpu_ctx_alloc() which is called from amdgpu_ctx_ioctl(), where we've called amdgpu_ctx_priority_is_valid() already first thing in the function.

gpu/drm: Eliminate DRM_SCHED_PRIORITY_UNSET

2023-10-18T00:35:38+00:00

Eliminate DRM_SCHED_PRIORITY_UNSET, value of -2, whose only user was amdgpu. Furthermore, eliminate an index bug, in that when amdgpu boots, it calls drm_sched_entity_init() with DRM_SCHED_PRIORITY_UNSET, which uses it to index sched->sched_rq[].

drm/amdgpu: Unset context priority is now invalid

2023-10-18T00:35:38+00:00

A context priority value of AMD_CTX_PRIORITY_UNSET is now invalid--instead of carrying it around and passing it to the Direct Rendering Manager--and it becomes AMD_CTX_PRIORITY_NORMAL in amdgpu_ctx_ioctl(), the gateway to context creation.

drm/amdgpu: add VM generation token

2023-06-15T15:37:55+00:00

Instead of using the VRAM lost counter add a 64bit token which indicates if a context or job is still valid to use. Should the VRAM be lost or the page tables need re-creation the token will change indicating that userspace needs to act and re-create the contexts and re-submit the work.

drm/amdgpu: add new flag to AMDGPU_CTX_QUERY2

2023-06-09T13:20:55+00:00

OpenGL EXT_robustness extension expects the driver to stop reporting GUILTY_CONTEXT_RESET when the reset has completed and the GPU is ready to accept submission again. This commit adds a AMDGPU_CTX_QUERY2_FLAGS_RESET_IN_PROGRESS flag, that let the UMD know that the reset is still not finished.
