[libvirt PATCH] qemu_firmware: select correct firmware for AMD SEV-ES
by Pavel Hrdina
When using firmware auto-selection and user enables AMD SEV-ES we need
to pick correct firmware that actually supports it. This can be detected
by having `amd-sev-es` in the firmware JSON description.

[libvirt PATCH v2 0/7] Enable sanitizers
by Tim Wiederhake
This series enables and adds AddressSanitizer and UndefinedBehaviorSanitizer
builds to the CI.
See:
https://clang.llvm.org/docs/AddressSanitizer.html and
https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html
These sanitizers already found some issues in libvirt, e.g.
4eb7c621985dad4de911ec394ac628bd1a5b29ab,
1294de209cee6643511265c7e2d4283c047cf652,
8b8c91f487592c6c067847ca59dde405ca17573f, or
1c34211c22de28127a509edbf2cf2f44cb0d891e.
There exist two more relevant sanitizers, ThreadSanitizer and MemorySanitizer.
Unfortunately, those two require an instrumented build of all dependencies,
including libc, to work correctly.
Note that clang and gcc have different implementations of these sanitizers,
hence the introduction of two new jobs to the CI. The latter one issues a
warning about the use of LD_PRELOAD in `virTestMain`, which in this
particular case can be safely ignored by setting `ASAN_OPTIONS` to
verify_asan_link_order=0` for the gcc build.
Changes since V1:
Incorporated changes suggested by Pavel, except for #6 (now #7): The statement
in https://listman.redhat.com/archives/libvir-list/2021-May/msg00070.html on
the sanitizers working with Fedora 33 is wrong, I was fooled by caching. The
bug described there is present in Fedora 33, 34, and Rawhide.
Cheers,
Tim

[libvirt PATCH] cpu_map: Add cpu feature avx-vnni
by Tim Wiederhake
"avx-vvni" was introduced to qemu in commit
c1826ea6a052084f2e6a0bae9dd5932a727df039, adding it Cooperlake.
This feature is currently not used by any libvirt CPU models, but its
addition silences a warning from sync_qemu_i386.py:
```
warning: Unknown feature 'CPUID_7_1_EAX_AVX_VNNI'
warning: Feature unknown to libvirt: CPUID_7_1_EAX_AVX_VNNI

[libvirt PATCH v2 0/7] Enable autostarting mediated devices
by Jonathon Jongsma
This series replaces the initial patch that was recently reverted. It
implements the autostart feature using a new virNodeDeviceGet/SetAutostart()
API that is consistent with how other libvirt objects handle autostart. It also
adds a counterpart virsh command nodedev-autostart.
In order to easily check the 'autostart' status of the device (since it is no
longer part of the device xml), a new virsh command is introduced:
nodedev-info. This also presents a few more basic bits of information about the
device, including 'active' and 'persistent' status, which requires exposing new
APIs on the node device: IsActive() and IsPersistent(). These APIs are
consistent with existing libvirt objects.
Changes in version 2:
- Parse the autostart property from mdevctl output.
- only re-sending patch 2/7, all others were already ACKED
Jonathon Jongsma (7):
api: add virNodeDevice(Get|Set)Autostart()
nodedev: implement virNodeDevice(Get|Set)Autostart()
nodedev: Add tests for mdevctl autostart command
virsh: add nodedev-autostart
api: add virNodeDeviceIsPersistent()/IsActive()
nodedev: Implement virNodeDeviceIsPersistent()/IsActive()
virsh: add nodedev-info

[RFC QEMU PATCH] ui: Make the DisplayType enum entries conditional
by Thomas Huth
Libvirt's "domcapabilities" command has a way to state whether
certain graphic frontends are available in QEMU or not. Originally,
libvirt looked at the "--help" output of the QEMU binary to determine
whether SDL was available or not (by looking for the "-sdl" parameter
in the help text), but since libvirt stopped doing this analysis of
the help text, the detection of SDL is currently broken, see:
https://bugzilla.redhat.com/show_bug.cgi?id=1790902
QEMU should provide a way via the QMP interface instead. The simplest
way, without introducing additional commands, is to make the DisplayType
enum entries conditional, so that the enum only contains the entries if
the corresponding CONFIG_xxx switches have been set. Unfortunately, this
only works for sdl, cocoa and spice, since gtk, egl-headless and curses
are hard-wired in the "data" section of the DisplayOptions, and thus
unfortunately always have to be defined.

[PATCH] domain_conf: Use virXMLFormatElement() more
by Michal Privoznik
I've identified some places (mostly by looking for
virBufferUse()) that can use virXMLFormatElement() instead of
open coded version of it. I'm sure there are many more places
that could use the same treatment. Let's cure them some other
time.
