The existing check has two problems:
1. Meson uses a private directory for the get_supported_arguments check.
./instrumentation-filter does not exist in that private directory (it is
copied into the root of the build-directory).
2. fsanitize-coverage-allowlist is unused when coverage instrumentation
is not configured. No instrumentation are passed for the
get_supported_arguments check
Thus the check always fails. To work around this, change the check to an
"if cc.compiles" check and provide /dev/null, instead of the real
filter.

Gathering statistics is important for development, for monitoring and
for performance measurement. There are tools such as kvm_stat that do
this and they rely on the _user_ knowing the interesting data points
rather than the tool (which can treat them as opaque).
The commands introduced in this commit introduce QMP support for
querying stats; the goal is to take the capabilities of these tools
and making them available throughout the whole virtualization stack,
so that one can observe, monitor and measure virtual machines without
having shell access + root on the host that runs them.
query-stats returns a list of all stats per target type (only VM
and vCPU to start); future commits add extra options for specifying
stat names, vCPU qom paths, and providers. All these are used by the
HMP command "info stats". Because of the development usecases around
statistics, a good HMP interface is important.
query-stats-schemas returns a list of stats included in each target
type, with an option for specifying the provider. The concepts in the
schema are based on the KVM binary stats' own introspection data, just
translated to QAPI.
There are two reasons to have a separate schema that is not tied to
the QAPI schema. The first is the contents of the schemas: the new
introspection data provides different information than the QAPI data,
namely unit of measurement, how the numbers are gathered and change
(peak/instant/cumulative/histogram), and histogram bucket sizes.
There's really no reason to have this kind of metadata in the QAPI
introspection schema (except possibly for the unit of measure, but
there's a very weak justification).
Another reason is the dynamicity of the schema. The QAPI introspection
data is very much static; and while QOM is somewhat more dynamic,
generally we consider that to be a bug rather than a feature these days.
On the other hand, the statistics that are exposed by QEMU might be
passed through from another source, such as KVM, and the disadvantages of
manually updating the QAPI schema for outweight the benefits from vetting
the statistics and filtering out anything that seems "too unstable".
Running old QEMU with new kernel is a supported usecase; if old QEMU
cannot expose statistics from a new kernel, or if a kernel developer
needs to change QEMU before gathering new info from the new kernel,
then that is a poor user interface.
The framework provides a method to register callbacks for these QMP
commands. Most of the work in fact is done by the callbacks, and a
large majority of this patch is new QAPI structs and commands.
Examples (with KVM stats):
- Query all VM stats:
{ "execute": "query-stats", "arguments" : { "target": "vm" } }
{ "return": [
{ "provider": "kvm",
"stats": [
{ "name": "max_mmu_page_hash_collisions", "value": 0 },
{ "name": "max_mmu_rmap_size", "value": 0 },
{ "name": "nx_lpage_splits", "value": 148 },
... ] },
{ "provider": "xyz",
"stats": [ ... ] }
] }
- Query all vCPU stats:
{ "execute": "query-stats", "arguments" : { "target": "vcpu" } }
{ "return": [
{ "provider": "kvm",
"qom_path": "/machine/unattached/device[0]"
"stats": [
{ "name": "guest_mode", "value": 0 },
{ "name": "directed_yield_successful", "value": 0 },
{ "name": "directed_yield_attempted", "value": 106 },

This change adds a new member, refresh_rate to QemuUIInfo in
include/ui/console.h. It represents the refresh rate of the
physical display backend, and it is more appropriate than
GUI update interval as the refresh rate which the emulated device
reports:
- sdl may set GUI update interval shorter than the refresh rate
of the physical display to respond to user-generated events.
- sdl and vnc aggressively changes GUI update interval, but
a guests is typically not designed to respond to frequent
refresh rate changes, or frequent "display mode" changes in
general. The frequency of refresh rate changes of the physical
display backend matches better to the guest's expectation.
QemuUIInfo also has other members representing "display mode",
which makes it suitable for refresh rate representation. It has
a throttling of update notifications, and prevents frequent changes
of the display mode.

The 'active' bit passes control over a qTD between the guest and the
controller: set to 1 by guest to enable execution by the controller,
and the controller sets it to '0' to hand back control to the guest.
ehci_state_writeback write two dwords to main memory using DMA:
the third dword of the qTD (containing dt, total bytes to transfer,
cpage, cerr and status) and the fourth dword of the qTD (containing
the offset).
This commit makes sure the fourth dword is written before the third,
avoiding a race condition where a new offset written into the qTD
by the guest after it observed the status going to go to '0' gets
overwritten by a 'late' DMA writeback of the previous offset.
This race condition could lead to 'cpage out of range (5)' errors,
and reproduced by:
./qemu-system-x86_64 -enable-kvm -bios $SEABIOS/bios.bin -m 4096 -device usb-ehci -blockdev driver=file,read-only=on,filename=/home/aengelen/Downloads/openSUSE-Tumbleweed-DVD-i586-Snapshot20220428-Media.iso,node-name=iso -device usb-storage,drive=iso,bootindex=0 -chardev pipe,id=shell,path=/tmp/pipe -device virtio-serial -device virtconsole,chardev=shell -device virtio-rng-pci -serial mon:stdio -nographic
(press a key, select 'Installation' (2), and accept the default

loading the Linux Kernel about once per 7 attempts. With the fix in
this commit it no longer fails)

Since about 2018 virglrenderer (commit fa835b0f88 "vrend: don't
hardcode context version") tries to open the highest available GL
context version. This is done by creating the known GL context
versions from the highest to the lowest until (*create_gl_context)
returns a context != NULL.
This does not work properly with
the current QEMU gd_gl_area_create_context() function, because
gdk_gl_context_realize() on Wayland creates a version 3.0 legacy
context if the requested GL context version can't be created.
In order for virglrenderer to find the highest available GL
context version, return NULL if the created context version is
lower than the requested version.
This fixes the following error:
QEMU started with -device virtio-vga-gl -display gtk,gl=on.

information can be seen on the host.

We inadvertently broke the ability to run local builds when the code
was re-factored. The result was the run stanza failing to find the
docker image with it's qemu/ prefix.

The job definitions recently got a second "variables:" section by
accident and thus are failing now if one tries to run them. Merge
the two sections into one again to fix the issue.
And while we're at it, bump the timeout here (70 minutes are currently
not enough for the aarch64 job). The jobs are marked as manual anyway,
so if the user starts them, they want to see their result for sure and
then it's annoying if the job timeouts too early.
