Subject: [PATCH 1/4] KVM: x86: mark synthetic SMM vmexit as SVM_EXIT_SW
Date: Tue, 1 Mar 2022 15:55:23 +0200 [thread overview]
Message-ID: <20220301135526.136554-2-mlevitsk@redhat.com> (raw)
In-Reply-To: <20220301135526.136554-1-mlevitsk@redhat.com>
Use a dummy unused vmexit reason to mark the 'VM exit' that is happening
when kvm exits to handle SMM, which is not a real VM exit.
This makes it a bit easier to read the KVM trace, and avoids
other potential problems.
