[Qemu-devel] [PULL v3 36/42] i386: Define -IBRS, -noTSX, -IBRS versions of CPU models |
|
Date: |
Tue, 2 Jul 2019 12:35:29 -0300 |
Add versions of CPU models that are equivalent to their -IBRS,
-noTSX and -IBRS variants.
The separate variants will eventually be removed and become
aliases for these CPU versions.
