Subject: [PATCH v4 5/6] kvm/i386: Use a per-VM check for SMM capability
Date: Fri, 25 Sep 2020 14:03:39 -0500	[thread overview]
Message-ID: <eaec49f1ce4c8fd69277b1a7c374dcd87b9bb95d.1601060620.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1601060620.git.thomas.lendacky@amd.com>

From: Tom Lendacky <thomas.lendacky@amd.com>

SMM is not currently supported for an SEV-ES guest by KVM. Change the SMM
capability check from a KVM-wide check to a per-VM check in order to have
a finer-grained SMM capability check.
