[Qemu-devel] [PATCH 17/22] target-i386: replace uint32_t vendor fields by vendor string in x86_def_t |
Date: |
Fri, 7 Sep 2012 22:55:06 +0200 |
Vendor property setter takes string as vendor value but cpudefs
use uint32_t vendor[123] fields to define vendor value. It makes it
difficult to unify and use property setter for values from cpudefs.
To allow simplify code by using vendor property setter, vendor[123]
fields are converted into vendor[13] array to keep its value. And
vendor property setter is used to access/set value on CPU.
[ehabkost: rebase on top of my unduplicate-features branch]
[ehabkost: fix the new CPU models to use the string .vendor field, too,
on the CPU model array]
[ehabkost: keep CPUID_VENDOR_AMD_[123] #defines, as they are used
in the AMD CPU feature alias handling]
