This series adds the support for following features in qemu.
1. RAS feature bits (SUCCOR, McaOverflowRecov)
2. perfmon-v2
3. Update EPYC-Genoa to support perfmon-v2 and RAS bits
4. Support for bits related to SRSO (sbpb, ibpb-brtype, srso-user-kernel-no)
5. Added support for feature bits CPUID_Fn80000021_EAX/CPUID_Fn80000021_EBX
to address CPUID enforcement requirement in Turin platforms.
6. Add support for EPYC-Turin.
Queued, thanks. I looked at
https://gitlab.com/qemu-project/qemu/-/issues/2571 and I think it's
caused by the ignore_msrs=1 parameter on the KVM kernel module.
However, can you look into adding new CPUID_SVM_* bits?
Thanks,
Paolo
