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

Posted by Tim Wiederhake 1 week, 5 days 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.

See also
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.
