This patchset is to expose two new features for intel processors which support them, like Sapphire Rapids. SERIALIZE is a faster serializing instruction which does not modify registers, arithmetic flags or memory, will not cause VM exit. TSX suspend load tracking instruction aims to give a way to choose which memory accesses do not need to be tracked in the TSX read set.
Changelog: v2 Add kernel feature enumeration patch to fix build error
Cathy Zhang (2): x86: Expose SERIALIZE for supported cpuid x86: Expose TSX Suspend Load Address Tracking
Ricardo Neri (1): x86/cpufeatures: Add enumeration for SERIALIZE instruction
Kyung Min Park (1): x86/cpufeatures: Enumerate TSX suspend load address tracking instructions
