Subject: [PATCH v3 11/16] target-s390x: Add cpu class initialization routines
Date: Mon,  2 Mar 2015 13:44:03 +0100	[thread overview]
Message-ID: <1425300248-40277-12-git-send-email-mimu@linux.vnet.ibm.com> (raw)
In-Reply-To: <1425300248-40277-1-git-send-email-mimu@linux.vnet.ibm.com>

This patch provides routines to dynamically update the previously defined
S390 cpu classes in the current host context. The main function performing
this process is s390_setup_cpu_classes(). It takes the current host context
as parameter to setup the classes accordingly. It basically performs the
following sub-tasks:

- Update of cpu classes with accelerator specific host and QEMU properties
- Mark adequate cpu class as default cpu class to be used for cpu model 'host'
- Invalidate cpu classes not supported by this hosting machine
- Define machine type aliases to latest GA number of a processor model
- Define aliases for common cpu model names
- Set cpu model alias 'host' to default cpu class

Forthermore the patch provides the following routines:

- cpu_desc_avail(), s390 specific stub indicating that list_cpus() can run
- s390_cpu_classes_initialized(), test if cpu classes have been initialized
- s390_probe_mode(), indicates if probe mode is active
