From: Sean Christopherson Date: Sat, 21 Dec 2019 04:45:13 +0000 (-0800) Subject: KVM: VMX: Allow KVM_INTEL when building for Centaur and/or Zhaoxin CPUs X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8f63aaf5c493c6502a058585cdfa3c71cdf8c44a;p=linux.git KVM: VMX: Allow KVM_INTEL when building for Centaur and/or Zhaoxin CPUs Change the dependency for KVM_INTEL, i.e. KVM w/ VMX, from Intel CPUs to any CPU that supports the IA32_FEAT_CTL MSR and thus VMX functionality. This effectively allows building KVM_INTEL for Centaur and Zhaoxin CPUs.
