Subject: [PATCH 29/30] selftests: kvm: fix smm test on SVM
Date: Fri, 29 May 2020 11:39:33 -0400 [thread overview]
Message-ID: <20200529153934.11694-30-pbonzini@redhat.com> (raw)
In-Reply-To: <20200529153934.11694-1-pbonzini@redhat.com>
From: Vitaly Kuznetsov <vkuznets@redhat.com>
KVM_CAP_NESTED_STATE is now supported for AMD too but smm test acts like
it is still Intel only.
