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 gfx shadow CS IOCTL support

Add support for submitting the shadow update packet when submitting an IB. Needed for MCBP on GFX11. v2: update API for CSA (Alex) v3: fix ordering; SET_Q_PREEMPTION_MODE most come before COND_EXEC Add missing check for AMDGPU_CHUNK_ID_CP_GFX_SHADOW in amdgpu_cs_pass1() Only initialize shadow on first use (Alex) v4: Pass parameters rather than job to new ring callback (Alex) v5: squash in change to call SET_Q_PREEMPTION_MODE/COND_EXEC before RELEASE_MEM to complete the UMDs use of the shadow (Alex) Reviewed-by: Christian König Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: cleanup SPM support a bit

2022-12-14T14:48:32+00:00

This should probably not access job->vm and also emit the SPM switch under the conditional execute. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: fix GDS/GWS/OA switch handling

2022-12-14T14:48:32+00:00

Bas pointed out that this isn't working as expected and could cause crashes. Fix the handling by storing the marker that a switch is needed inside the job instead. Reported-by: Bas Nieuwenhuizen Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: add gang submit backend v2

2022-09-20T16:40:32+00:00

Allows submitting jobs as gang which needs to run on multiple engines at the same time. Basic idea is that we have a global gang submit fence representing when the gang leader is finally pushed to run on the hardware last. Jobs submitted as gang are never re-submitted in case of a GPU reset since this won't work and will just deadlock the hardware immediately again. v2: fix logic inversion, improve documentation, fix rcu Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
