[Qemu-devel] [PATCH 06/28] sparc: convert cpu features to qdev properties |
Date: |
Fri, 14 Jul 2017 15:51:57 +0200 |
SPARC is the last target that uses legacy way of parsing
and initializing cpu features, drop legacy approach and
convert features to properties so that SPARC could as minimum
benefit from generic cpu_generic_init(), common with
x86 +-feat parser
PS:
the main purpose is to remove legacy way of cpu creation as
a blocker for unifying cpu creation code across targets.
