Subject: [libvirt][PATCH v2 0/3] Improve PPC CPU driver
Date: Tue, 3 Sep 2013 14:28:22 +0800
From: Li Zhang <zhlcindy(a)gmail.com To:
libvir-list(a)redhat.com, jdenemar(a)redhat.com
CC: bpradip(a)in.ibm.com, Li Zhang <zhlcindy(a)linux.vnet.ibm.com
From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com
Currently, PPC CPU driver doesn't support to parse guest data.
It can't pass CPU parameters to Qemu command line.
This patchset is to implement .guestData to support to parse guest
CPU configuration and .update to support host-model and
host-passthrough.
The guest CPU configuration is as the following:
<cpu match='exact'
<model>POWER7_v2.3</model
<vendor>IBM</vendor </cpu
v2 -> v1:
* Remove features functions calling for non-x86 platform (Doug
Goldstein)
* Improve update code.
* Merge update code with guestData.
Li Zhang (3):
Remove CPU features check for non-x86 platform.
cpu: Implement guestData and update for PPC
cpu: Add cpu test cases for PPC CPU driver.
