commit 5afb11ac409185d862f405b2509b89abc2311bf5 Author: Matthew Barnes <matthew.barnes@xxxxxxxxx> AuthorDate: Wed Aug 21 16:34:37 2024 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Fri Sep 6 14:42:18 2024 +0100 x86/cpufeatures: Add new cpuid features in SPR to featureset Upon running `xen-cpuid -v` on a host machine with Sapphire Rapids within Dom0, there exist unrecognised features. This patch adds these features as macros to the CPU featureset, disabled by default.
