Subject: [PATCH v2 11/13] KVM: selftests: add support for creating SEV-ES guests
Date: Thu, 16 Dec 2021 11:13:56 -0600	[thread overview]
Message-ID: <20211216171358.61140-12-michael.roth@amd.com> (raw)
In-Reply-To: <20211216171358.61140-1-michael.roth@amd.com>

Only a couple KVM_SEV_* ioctls need to be handled differently for
SEV-ES. Do so when the specified policy indicates SEV-ES support.
