| O-Subject: [RHEL-7.5 qemu-kvm PATCH 2/2] target-i386/cpu: Add new EPYC CPU model |
| Bugzilla: 1450396 |

| |
| Add a new base CPU model called 'EPYC' to model processors from AMD EPYC |
| family (which includes EPYC 76xx,75xx,74xx, 73xx and 72xx). |
| |
| The following features bits have been added/removed compare to Opteron_G5 |
| |
| Added: monitor, movbe, rdrand, mmxext, ffxsr, rdtscp, cr8legacy, osvw, |
| fsgsbase, bmi1, avx2, smep, bmi2, rdseed, adx, smap, clfshopt, sha |
| xsaveopt, xsavec, xgetbv1, arat |
| |
| Removed: xop, fma4, tbm |
| |
| Backport notes: |
| * ARAT feature removed. It is already disabled by the rhel7.2.0 |
| compat code in qemu-kvm-rhev, so it keeps migration compatibility |
| with qemu-kvm-rhev. |
