- Substantial rework of the spec file:
* the 'make check' testsuite now runs in the %check section of
the main package, not in a subpackage
* switched from %setup to %autosetup
* rearranged the content in order to minimize the use of %if,
%ifarch, etc
- Properly fix bsc#1198038, CVE-2022-0216
* Patches added:
scsi-lsi53c895a-really-fix-use-after-fre.patch
tests-qtest-Move-the-fuzz-tests-to-x86-o.patch
- Make temp dir (for update_git.sh) configurable
- Added new subpackages (audio-dbus, ui-dbus)
- bsc#1199018 was never fixed in Factory's QEMU 6.2. It is
now (since the patches are already in SeaBIOS 1.16.0)
- Some tests are having issues when run in OBS. They seem to be
due to race conditions, triggered by resource constraints of
OBS workers. Let's disable them for now, while looking for a fix
- Update to v7.0.0. For full release notese, see:

Subject: hostmem: default the amount of prealloc-threads to smp-cpus
|
|
|
|
Git-commit: f8d426a6852c560fdd8648ae961c8189909a4b82
|
|
References: bsc#1197084
|
|
|
|
Prior to the introduction of the prealloc-threads property, the amount
|
|
of threads used to preallocate memory was derived from the value of
|
|
smp-cpus passed to qemu, the amount of physical cpus of the host
|
|
and a hardcoded maximum value. When the prealloc-threads property
|
|
was introduced, it included a default of 1 in backends/hostmem.c and
|
|
a default of smp-cpus using the sugar API for the property itself. The
|
|
latter default is not used when the property is not specified on qemu's
|
|
command line, so guests that were not adjusted for this change suddenly
|
|
started to use the default of 1 thread to preallocate memory, which
|
|
resulted in observable slowdowns in guest boots for guests with large
|
|
memory (e.g. when using libvirt <8.2.0 or managing guests manually).
|
|
|
|
This commit restores the original behavior for these cases while not
|
|
impacting guests started with the prealloc-threads property in any way.
|
