Subject: [PATCH v5 6/6] sev/i386: Enable an SEV-ES guest based on SEV policy
Date: Thu, 14 Jan 2021 17:12:36 -0600 [thread overview]
Message-ID: <38989f30c7243296111352d769e4e184f3036cbb.1610665956.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1610665956.git.thomas.lendacky@amd.com>
From: Tom Lendacky <thomas.lendacky@amd.com>
Update the sev_es_enabled() function return value to be based on the SEV
policy that has been specified. SEV-ES is enabled if SEV is enabled and
the SEV-ES policy bit is set in the policy object.
