[PATCH 00/34] Add HMM-based SVM memory manager to KFD v3

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

 



Since the last patch series on March 22, I integrated all fixes into
the original patch series. An additonal fix was added for handling
failed migrations during GPU page faults. (A bigger rework of
migrations and VRAM mappings will come in the future.) Support for
per-process XNACK mode selecation was added for Aldebaran. The
initialization of svm_migrate was moved to happend before
kfd_topology_add_device in order to fix reporting of the
SVMAPI_SUPPORTED capability. An updated kfdtest now checks this
capability before running any SVM tests.

Support for SVM can now be controlled by a Kconfig option added in
patch 34.

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