[Qemu-devel] [PATCH] taget-i386: Broadwell CPU model

[Eduardo Habkost]

This adds a new CPU model named "Broadwell". It has all the features
from Haswell, plus PREFETCHW, RDSEED, ADX, SMAP.

PREFETCHW was already supported as "3dnowprefetch".

RDSEED, ADX was added on Linux v3.15-rc1.

SMAP was added on Linux v3.15-rc2.
