Subject: [PATCH 08/43] target/i386: Add support for EPYC-Turin model
RH-Author: John Allen <None>
RH-MergeRequest: 377: Update EPYC Models and Feature Bits
RH-Jira: RHEL-52650
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Commit: [6/6] 3d8805bafc53da2bd5a2b2b96cc892ea7ca9f2b3 (johnalle/qemu-kvm-fork)
Add the support for AMD EPYC zen 5 processors (EPYC-Turin).
Add the following new feature bits on top of the feature bits from
the previous generation EPYC models.
movdiri : Move Doubleword as Direct Store Instruction
movdir64b : Move 64 Bytes as Direct Store Instruction
avx512-vp2intersect : AVX512 Vector Pair Intersection to a Pair
of Mask Register
avx-vnni : AVX VNNI Instruction
prefetchi : Indicates support for IC prefetch
sbpb : Selective Branch Predictor Barrier
ibpb-brtype : IBPB includes branch type prediction flushing
srso-user-kernel-no : Not vulnerable to SRSO at the user-kernel boundary
