Subject: [PATCH 1/3] KVM: VMX: fix comment to add LBR to passthrough MSRs
Date: Fri, 16 Feb 2024 17:45:11 -0800	[thread overview]
Message-ID: <20240217014513.7853-2-dongli.zhang@oracle.com> (raw)
In-Reply-To: <20240217014513.7853-1-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").
