[v1] Add missing feature detection to sync tool in cpu_map

[libvirt PATCH 0/3] Add missing feature detection to sync tool in cpu_map

Posted by Tim Wiederhake 3 years, 5 months ago

sync_qemu_i386.py in src/cpu_map is a tool to sync CPU models from qemu
with libvirt. It currently has no provisions for detecting new features
that are not implemented in libvirt yet. This series changes that.

https://www.redhat.com/archives/libvir-list/2020-November/msg00271.html.

libvirt is currently missing three x86 CPU models: Denverton,
KnightsMill, and Snowridge; and seven features: core-capability, fsrm,
perfctr-core, split-lock-detect, vmx-eptp-switching, vmx-pml, and
vmx-rdseed-exit.

For the Snowridge CPU model and the core-capability and split-lock-detect
features, see also
https://www.redhat.com/archives/libvir-list/2020-November/msg00924.html.

"Ohnosecond", Noun, /ˈoʊnoʊˌsɛkənd/: The fraction of time between
making a mistake and realizing it.

Disregard this series. There is a bug in the sync_qemu_i386.py script
that needs adressing first. Will send out v2 later.
