This is the first try of the new -no-user-config option.
Patches 1 to 3 just move some code around, patch 4 just adds the new option
without adding any new config file. Patch 5 finally creates a /usr/share/qemu
/cpus-x86_64.conf file, with the CPU models we currently have on Qemu.
Reference to previous discussion:
- http://marc.info/?l=qemu-devel&m=133278877315665
This series depends on the following:
Subject: [PATCH v5 00/14] configure: --with-confsuffix option
Message-Id: <1334778950-18660-1-git-send-email-ehabkost(a)redhat.com>
Eduardo Habkost (5):
move code to read default config files to a separate function
eliminate arch_config_name variable
move list of default config files to an array
implement -no-user-config command-line option
move CPU definitions to /usr/share/qemu/cpus-x86_64.conf

Function added to arch_init.c because it depends on arch-specific

Coding style is off here. While you're at it, you should make userconfig a bool.

Let's use a bool here and move this to qemu-config.h. The declaration can live
there even if the definition is in arch_init.c

This is the first try of the new -no-user-config option.
Patches 1 to 3 just move some code around, patch 4 just adds the new option
without adding any new config file. Patch 5 finally creates a /usr/share/qemu
/cpus-x86_64.conf file, with the CPU models we currently have on Qemu.
Reference to previous discussion:
- http://marc.info/?l=qemu-devel&m=133278877315665
This series depends on the following:
Subject: [PATCH v5 00/14] configure: --with-confsuffix option
Message-Id: <1334778950-18660-1-git-send-email-ehabkost(a)redhat.com>
Eduardo Habkost (5):
move code to read default config files to a separate function
eliminate arch_config_name variable
move list of default config files to an array
implement -no-user-config command-line option
move CPU definitions to /usr/share/qemu/cpus-x86_64.conf
This is a huge improvement from libvirt point of view. Thanks Eduadro. I'll
prepare corresponding libvirt patches.
