Subject: [PATCH v2 07/15] KVM: VMX: Support passthrough of architectural LBRs
Date: Thu, 24 Nov 2022 23:05:56 -0500	[thread overview]
Message-ID: <20221125040604.5051-8-weijiang.yang@intel.com> (raw)
In-Reply-To: <20221125040604.5051-1-weijiang.yang@intel.com>

From: Paolo Bonzini <pbonzini@redhat.com>

MSR_ARCH_LBR_* can be pointed to by records->from, records->to and
records->info, so list them in is_valid_passthrough_msr.
