amd-drm-next-6.9-2024-02-09:
amdgpu:
- Validate DMABuf imports in compute VMs
- Add RAS ACA framework
- PSP 13 fixes
- Misc code cleanups
- Replay fixes
- Atom interpretor PS, WS bounds checking
- DML2 fixes
- Audio fixes
- DCN 3.5 Z state fixes
- Remove deprecated ida_simple usage
- UBSAN fixes
- RAS fixes
- Enable seq64 infrastructure
- DC color block enablement
- Documentation updates
- DC documentation updates
- DMCUB updates
- S3 fixes
- VCN 4.0.5 fixes
- DP MST fixes
- SR-IOV fixes
amdkfd:
- Validate DMABuf imports in compute VMs
- SVM fixes
- Trap handler updates
radeon:
- Atom interpretor PS, WS bounds checking
- Misc code cleanups
UAPI:
- Bump KFD version so UMDs know that the fixes that enable the management of
VA mappings in compute VMs using the GEM_VA ioctl for DMABufs exported from KFD are present
- Add INFO query for input power. This matches the existing INFO query for average
power. Used in gaming HUDs, etc.
