Subject: [PATCH v9 03/12] perf/x86/intel/pt: Add new bit definitions for Intel PT MSRs
Date: Tue, 22 May 2018 12:52:06 +0800 [thread overview]
Message-ID: <1526964735-16566-4-git-send-email-luwei.kang@intel.com> (raw)
In-Reply-To: <1526964735-16566-1-git-send-email-luwei.kang@intel.com>
These bit definitions are use for emulate MSRs read/write
for KVM. For example, IA32_RTIT_CTL.FabricEn[bit 6] is available
only when CPUID.(EAX=14H, ECX=0):ECX[bit 3] = 1. If KVM guest
try to set this bit with CPUID.(EAX=14H, ECX=0):ECX[bit3] = 0
a #GP would be injected to KVM guest.
