[libvirt PATCHv2] ci: adapt to 'dtrace' package split
by Ján Tomko 25 Sep '24

Fedora has decided to separate dtrace out of the systemtap-sdt-devel package: https://fedoraproject.org/wiki/Changes/Separate_dtrace_package Similarly, these are split in OpenSUSE Tumbleweed, however in a backward-compatbile way: https://build.opensuse.org/package/show/openSUSE:Factory/systemtap Require the new 'systemtap' package mapping, as well as the old 'dtrace'.

[PATCH] cpu_map: Fix SierraForest CPU model
by Jiri Denemark 25 Sep '24

25 Sep '24

The model was defined with two CPU features that cannot be explicitly configured in QEMU (it knows the MSR bits, but there's no name associated with them). The features should have never existed in the CPU map. While removing them from the list of features and existing CPU models is not trivial (to avoid compatibility issues), we can at least fix the SierraForest CPU model added in this release cycle. The rest will be handled later in a separate series.
