Subject: [PATCH v2 1/3] KVM: VMX: fix comment to add LBR to passthrough MSRs
Date: Fri, 23 Feb 2024 12:21:02 -0800 [thread overview]
Message-ID: <20240223202104.3330974-2-seanjc@google.com> (raw)
In-Reply-To: <20240223202104.3330974-1-seanjc@google.com>
From: Dongli Zhang <dongli.zhang@oracle.com>
According to the is_valid_passthrough_msr(), the LBR MSRs are also
passthrough MSRs, since the commit 1b5ac3226a1a ("KVM: vmx/pmu:
Pass-through LBR msrs when the guest LBR event is ACTIVE").
