[Qemu-devel] [PATCH 15/22] target-i386: introduce vendor-override property |
Date: |
Wed, 26 Sep 2012 22:32:51 +0200 |
currently 'cpuid_vendor_override' can be set only via cmd line cpu_model
string. But setting it in 'vendor' property prevents using 'vendor'
property on its own without setting cpuid_vendor_override.
So fix/remove enabling cpuid_vendor_override from "vendor" property setter.
It's up-to cpu_model string parser to maintain legacy behavior when user
overrides vendor on command line.
v2:
- convert cpuid_vendor_override to bool to reflect its real usage
