[PATCH 00/34] Add HMM-based SVM memory manager to KFD v5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Updates since v4:
- Rebased on upstream.
- Added SPDX license headers and updated copyright on added files
- Disabled XNACK on GFXv10 and later GPUs that don't support shader
  preemption on fault
- Updated PTE flags for Aldebaran

This series and the corresponding ROCm Thunk and KFDTest changes are also
available on gitub and patchwork.
