In the cases where I've looked at the underlying log, this seems to
be in the migration/multifd/tcp/plain/cancel subtest. Disable that
specific subtest by default until somebody can track down the
underlying cause. Enthusiasts can opt back in by setting
QEMU_TEST_FLAKY_TESTS=1 in their environment.
We might need to disable more parts of this test if this isn't
sufficient to fix the flakiness.

When virt ACPI files were added, lots of duplicates were created because
we forgot that there's a no-prefix fallback: e.g. if
tests/data/acpi/virt/APIC.memhp is not there then test will use
tests/data/acpi/virt/APIC.
Drop these.
These were found with
$find tests/data/acpi/ -type f -exec sha256sum '{}' ';'|sort -d|uniq -w 64 --all-repeated=separate
(trick: -d does a dictionary sort so a no-suffix file ends up first).
Note: there are still a bunch of issues with duplicates left even after this.
First pc and q35 are often identical.
Second, sometimes files are identical but not identical to the default
fallback, e.g.
tests/data/acpi/pc/SLIT.cphp and tests/data/acpi/pc/SLIT.memhp
or
tests/data/acpi/q35/HMAT.acpihmat-noinitiator and tests/data/acpi/virt/HMAT.acpihmatvirt
Finding a way to deduplicate these is still a TODO item - softlinks
maybe?
We also need to make rebuild-expected-aml.sh smarter about not creating
these duplicates in the 1st place.
And maybe we should use softlinks instead of relying on a fallback
to make it explicit what version does each test expect?

According to g_tree_foreach() documentation:
"The tree may not be modified while iterating over it (you can't
add/remove items)."
compare_trees()/diff_tree() fail to respect this rule.
Historically GLib2 used a slice allocator for the GTree APIs
which did not immediately release the memory back to the system
allocator. As a result QEMU's use-after-free bug was not visible.
With GLib > 2.75.3 however, GLib2 has switched to using malloc
and now a SIGSEGV can be observed while running test-vmstate.
Get rid of the node removal within the tree traversal. Also
check the trees have the same number of nodes before the actual
diff.

since binutils is pretty old, it fails our CI repeatedly during the
compilation of tricore-binutils. We created a precompiled version using
the debian docker image and download it instead of building it ourself.
We also updated the package to include a newer version of binutils, gcc,
and newlib. The default TriCore ISA version used by tricore-as changed
from the old version, so we have to specify it now. If we don't
'test_fadd' fails with 'unknown opcode'.
The new assembler also picks a new encoding in ld.h which fails the
'test_ld_h' test. We fix that by using the newest TriCore CPU for QEMU.
The old assembler accepted an extra ')' in 'test_imask'. The new one
does not, so lets remove it.

The TuxRun project (www.tuxrun.org) uses QEMU to run tests on a wide
variety of kernel configurations on wide range of our emulated
platforms. They publish a known good set of images at:
https://storage.tuxboot.com/
to help with bisecting regressions in either the kernel, firmware or
QEMU itself. The tests are pretty lightweight as they contain just a
kernel with a minimal rootfs which boots a lot faster than most of the
distros. In time they might be persuaded to version their known good
baselines and we can then enable proper checksums.
For a couple of tests we currently skip:
- mips64, a regression against previous stable release
- sh4, very unstable with intermittent oops
Total run time: 340s (default) -> 890s (debug)

replay API is used deeply within TCG common code (common to user
and system emulation). Unfortunately "sysemu/replay.h" requires
some QAPI headers for few system-specific declarations, example:
void replay_input_event(QemuConsole *src, InputEvent *evt);
Since commit c2651c0eaa ("qapi/meson: Restrict UI module to system
emulation and tools") the QAPI header defining the InputEvent is
not generated anymore.
To keep it simple, extract the 'core' replay prototypes to a new
"exec/replay-core.h" header which we include in the TCG code that
doesn't need the rest of the replay API.

We are facing the issues that some test logs in the gitlab CI are
too big (and thus cut off). The rtl8139-test is one of the few qtests
that prints many lines of output by default when running with V=1, so
it contributes to this problem. Almost all other qtests are silent
with V=1 and only print debug messages with V=2 and higher. Thus let's
change the rtl8139-test to behave more like the other tests and only
print the debug messages with V=2 (or higher).
