[PATCH v2 1/1] drm/amdkfd: Add sysfs bitfields and enums to uAPI
Felix Kuehling
Felix.Kuehling at amd.com
Mon Sep 13 21:23:20 UTC 2021
These bits are de-facto part of the uAPI, so declare them in a uAPI header.
The corresponding bit-fields and enums in user mode are defined in
https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/blob/master/include/hsakmttypes.h
HSA_CAP_... -> HSA_CAPABILITY
HSA_MEM_HEAP_TYPE_... -> HSA_HEAPTYPE
HSA_MEM_FLAGS_... -> HSA_MEMORYPROPERTY
HSA_CACHE_TYPE_... -> HsaCacheType
HSA_IOLINK_TYPE_... -> HSA_IOLINKTYPE
HSA_IOLINK_FLAGS_... -> HSA_LINKPROPERTY
