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.
