[Qemu-devel] [PATCH RFC 03/11] s390/qemu: cpu model cpu class definition |
|
Date: |
Wed, 2 Oct 2013 13:33:34 +0200 |
This patch implements the static part of the s390 cpu class definitions.
It defines single cpu models by means of virtual cpu ids which contain
information on the cpu generation, the machine class, the GA number and
the machine type. The cpu id is used to instantiate a cpu classes per cpu
id.
