drm/amdgpu: use common defines for HUB faults

drm/amdgpu: rework how PTE flags are generated v3

2025-08-04T18:26:38+00:00

Previously we tried to keep the HW specific PTE flags in each mapping, but for CRIU that isn't sufficient any more since the original value is needed for the checkpoint procedure. So rework the whole handling, nuke the early mapping function, keep the UAPI flags in each mapping instead of the HW flags and translate them to the HW flags while filling in the PTEs. Only tested on Navi 23 for now, so probably needs quite a bit of more work. v2: fix KFD and SVN handling v3: one more SVN fix pointed out by Felix v4: squash in gfx12 fix from David Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: enable pdb0 for hibernation on SRIOV

2025-06-18T16:19:15+00:00

When switching to new GPU index after hibernation and then resume, VRAM offset of each VRAM BO will be changed, and the cached gpu addresses needed to updated. This is to enable pdb0 and switch to use pdb0-based virtual gpu address by default in amdgpu_bo_create_reserved(). since the virtual addresses do not change, this can avoid the need to update all cached gpu addresses all over the codebase.

drm/amdkfd: Support chain runlists of XNACK+/XNACK-

2025-05-16T17:37:29+00:00

If the MEC firmware supports chaining runlists of XNACK+/XNACK- processes, set SQ_CONFIG1 chicken bit and SET_RESOURCES bit 28. When the MEC/HWS supports it, KFD checks the XNACK+/XNACK- processes mix happens or not. If it does, enter over-subscription.

Add a callback to check if there is any condition detected by GMC block for reset on init. One case is if a pending NPS change request is detected. If reset is done because of NPS switch, refresh NPS info from discovery table. Signed-off-by: Lijo Lazar Reviewed-by: Feifei Xu Signed-off-by: Alex Deucher
