-------- Original Message -------- Subject: [libvirt][PATCH v2 0/3] Improve PPC CPU driver Date: Tue, 3 Sep 2013 14:28:22 +0800 From: Li Zhang <zhlcindy@gmail.com> To: libvir-list@redhat.com, jdenemar@redhat.com CC: bpradip@in.ibm.com, Li Zhang <zhlcindy@linux.vnet.ibm.com>
From: Li Zhang <zhlcindy@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.
