Subject: [PATCH v13 04/12] perf/x86/intel/pt: Add new bit definitions for PT MSRs
Date:   Wed, 24 Oct 2018 16:05:08 +0800
Message-Id: <1540368316-12998-5-git-send-email-luwei.kang@intel.com>
In-Reply-To: <1540368316-12998-1-git-send-email-luwei.kang@intel.com>
References: <1540368316-12998-1-git-send-email-luwei.kang@intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add bit definitions for Intel PT MSRs to support trace output
directed to the memeory subsystem and holds a count if packet
bytes that have been sent out.

These are required by the upcoming PT support in KVM guests
for MSRs read/write emulation.
