Subject: [PATCH v2 1/6] KVM: x86: SVM: add module param to control LBR virtualization
Date: Mon, 1 Nov 2021 16:03:19 +0200 [thread overview]
Message-ID: <20211101140324.197921-2-mlevitsk@redhat.com> (raw)
In-Reply-To: <20211101140324.197921-1-mlevitsk@redhat.com>
This is useful for debug and also makes it consistent with
the rest of the SVM optional features.
