From 4658a565f5536002c3a65e942eed0d877cd1d070 Mon Sep 17 00:00:00 2001
Message-Id: <4658a565f5536002c3a65e942eed0d877cd1d070@dist-git>
From: Jiri Denemark <jdenemar@redhat.com>

Subject: [PATCH] cpu_map: Add <decode> element to x86 CPU model definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The element specifies whether a particular CPU model can be used when
creating a CPU definition from raw CPUID/MSR data. The @host attribute
determines whether the CPU model can be used (host='on') for creating
CPU definition for host capabilities. Usability of the model for domain
capabilities and host-model CPU definitions is controlled by the @guest
attribute.
