Subject: [PATCH v2 16/16] KVM: VMX: Allow KVM_INTEL when building for Centaur and/or Zhaoxin CPUs
Date: Mon, 21 Oct 2019 17:12:35 -0700 [thread overview]
Message-ID: <20191022001235.2739-1-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191021234632.32363-1-sean.j.christopherson@intel.com>
Change the dependency for KVM_INTEL, i.e. KVM w/ VMX, from Intel CPUs to
any CPU that has IA32_FEATURE_CONTROL MSR and thus VMX functionality.
This effectively allows building KVM_INTEL for Centaur and Zhaoxin CPUs.
