[PATCH 0/2] KVM: x86: add support for CPUID leaf 0x80000021

From: Paolo Bonzini
Date: Wed Mar 09 2022 - 12:15:01 EST


CPUID leaf 0x80000021 defines some features (or lack of bugs) of AMD
processors. This small series implements it, and also synthesizes
for use on processors that do not have the "Null selector clear base"
erratum but do not support the leaf 0x80000021 either.
