Subject: [PATCH] target/i386: enumerate bit 56 of MSR_IA32_VMX_BASIC
Date: Wed, 20 Sep 2023 17:41:36 +0200	[thread overview]
Message-ID: <20230920154136.33171-1-pbonzini@redhat.com> (raw)

On parts that enumerate IA32_VMX_BASIC MSR bit as 1, any exception vector
can be delivered with or without an error code if the other consistency
checks are satisfied.
