[PATCH 2/2] x86/cpufeatures: Enumerate MOVDIR64B instruction

2018-10-24 Thread Fenghua Yu
MOVDIR64B moves 64-bytes as direct-store with 64-bytes write atomicity. Direct store is implemented by using write combining (WC) for writing data directly into memory without caching the data. In low latency offload (e.g. Non-Volatile Memory, etc), MOVDIR64B writes work descriptors (and data in
