Alex Bennée cf22f936f2 tests/tcg: don't allow clang as a cross compiler
Currently there are two problems.

The first is clang generates a preamble (that is always executed) to
stack xmm registers. This causes a ILLOP on the x86_64 softmmu tests
as SSE isn't enabled.

The second is the inline assembler in test-i386.c breaks clangs
compiler and I don't know how to fix it. Even with Theodore's patch
series (D5741445-7EFD-4AF1-8DB2-E4AFA93CBB1A@icloud.com) I still get
compiler failures.

For now lets just skip clang and allow it to fall back to the
containers which we know have compilers which work.

Matheus Ferst cf9b6d215e tests/docker: gcc-10 based images for ppc64{,le} tests
A newer compiler is needed to build tests for Power10 instructions. As
done for arm64 on c729a99d27, a new '-test-cross' image is created for
ppc64 and ppc64le. As done on 936fda4d77, a test for compiler support
is added to verify that the toolchain in use has '-mpower10'. Finally,
Unused images (docker-power-cross and docker-ppc64-cross) are removed.

Bastian Koppelmann 2d934b5951 tests/tcg/tricore: Add macros to create tests and first test 'abs'
This kind of tests is inspired by the riscv-tests repository. This adds
macros that makes it easy to create single instruction self containing
tests.

It is achieved by macros that create a test sequence for an
instruction and check for a supplied correct value. If the value is correct the
next instruction is tested. Otherwise we jump to fail handler that writes is
test number as a status code back to qemu that then exits on that status code.
If all tests pass we write back 0 as a status code and exit.

Bastian Koppelmann ac3c7c3f79 tests/tcg: Add docker_as and docker_ld cmds
At least for the TriCore target no easily available c compiler exists.
Thus we need to rely on "as" and "ld". This allows us to run them
through the docker image. We don't test the generation capabilities of
docker images as they are assumed to work.

Alex Bennée d8e706da6c tests/tcg: don't iterate through other arch compilers
There should only be one compiler per architecture. Those cases where
the same compiler can deal with a different architecture should be
explicitly set for both cross_cc and docker configurations. Otherwise
you get strangeness like:

  --cross-cc-aarch64=/bin/false

causing the logic to attempt to use a locally available
arm-linux-gnueabihf-gcc rather than forcing the use of the docker
image which is what is implied by the command line option.

Alessandro Di Federico afbdf0a44e docker: Add Hexagon image
This image is a little special because it takes a long time to build.
As such most users don't want to be doing that and just pull random
binaries from the ether as intended by the container gods. This
involves someone with credentials and a beefy machine running:

  make docker-image-debian-hexagon-cross V=1 NOCACHE=1 J=30
  docker tag qemu/debian-hexagon-cross registry.gitlab.com/qemu-project/qemu/qemu/debian-hexagon-cross
  docker push registry.gitlab.com/qemu-project/qemu/qemu/debian-hexagon-cross

With a suitable binary in the "cloud" a normal user will run:

  make docker-image-debian-hexagon-cross

or have it run for them through the dependency mechanism of our
over-engineered makefiles and get the binary they wanted. There are a
few wrinkles of course including needing to tweak the final image to
have the credentials of the user so we can actually do our cross
compiles.

Vladimir Sementsov-Ogievskiy e46354a8ae test-write-threshold: rewrite test_threshold_(not_)trigger tests
These tests use bdrv_write_threshold_exceeded() API, which is used only
for test (since pre-previous commit). Better is testing real API, which
is used in block.c as well.

So, let's call bdrv_write_threshold_check_write(), and check is
bs->write_threshold_offset cleared or not (it's cleared iff threshold
triggered).

Also we get rid of BdrvTrackedRequest use here. Note, that paranoiac
bdrv_check_request() calls were added in 8b1170012b to protect
BdrvTrackedRequest. Drop them now.

Right now there is no easy way for "check" to print a reproducer command.
Because such a reproducer command line would be huge, we can instead teach
check to start a command of our choice.  This can be for example a Python
unit test with arguments to only run a specific subtest.

Move the trailing empty line to print_env(), since it always looks better
and one caller was not adding it.

Paolo Bonzini 00dbc85e0e qemu-iotests: allow passing unittest.main arguments to the test scripts
Python test scripts that use unittest consist of multiple tests.
unittest.main allows selecting which tests to run, but currently this
is not possible because the iotests wrapper ignores sys.argv.

unittest.main command line options also allow the user to pick the
desired options for verbosity, failfast mode, etc.  While "-d" is
currently translated to "-v", it also enables extra debug output,
and other options are not available at all.

These command line options only work if the unittest.main testRunner
argument is a type, rather than a TestRunner instance.  Therefore, pass
the class name and "verbosity" argument to unittest.main, and adjust for
the different default warnings between TextTestRunner and unittest.main.

If mirror is READY than cancel operation is not discarding the whole
result of the operation, but instead it's a documented way get a
point-in-time snapshot of source disk.

So, we should not cancel any requests if mirror is READ and
force=false. Let's fix that case.

Note, that bug that we have before this commit is not critical, as the
only .bdrv_cancel_in_flight implementation is nbd_cancel_in_flight()
and it cancels only requests waiting for reconnection, so it should be
rare case.

Connor Kuehl 2b99cfce08 block/rbd: Add an escape-aware strchr helper
Sometimes the parser needs to further split a token it has collected
from the token input stream. Right now, it does a cursory check to see
if the relevant characters appear in the token to determine if it should
break it down further.

However, qemu_rbd_next_tok() will escape characters as it removes tokens
from the token stream and plain strchr() won't. This can make the
initial strchr() check slightly misleading since it implies
qemu_rbd_next_tok() will find the token and split on it, except the
reality is that qemu_rbd_next_tok() will pass over it if it is escaped.

Use a custom strchr to avoid mixing escaped and unescaped string
operations. Furthermore, this code is identical to how
qemu_rbd_next_tok() seeks its next token, so incorporate this custom
strchr into the body of that function to reduce duplication.

Marc-André Lureau 73e6aec652 sphinx: adopt kernel readthedoc theme
The default "alabaster" sphinx theme has a couple shortcomings:
- the navbar moves along the page
- the search bar is not always at the same place
- it lacks some contrast and colours

The "rtd" theme from readthedocs.org is a popular third party theme used
notably by the kernel, with a custom style sheet. I like it better,
perhaps others do too. It also simplifies the "Edit on Gitlab" links.

Tweak a bit the custom theme to match qemu.org style, use the
QEMU logo, and favicon etc.

Peter Maydell 2ed765fdee tests/qtest/migration-test: Use g_autofree to avoid leaks on error paths
Coverity notices that several places in the migration-test code fail
to free memory in error-exit paths.  This is pretty unimportant in
test case code, but we can avoid having to manually free the memory
entirely by using g_autofree.

The places where Coverity spotted a leak were relating to early exits
not freeing 'uri' in test_precopy_unix(), do_test_validate_uuid(),
migrate_postcopy_prepare() and test_migrate_auto_converge().  This
patch converts all the string-allocation in the test code to
g_autofree for consistency.

Peter Maydell 302585450c tests/qtest/npcm7xx_pwm-test.c: Avoid g_assert_true() for non-test assertions
In the glib API, the distinction between g_assert() and
g_assert_true() is that the former is for "bug, terminate the
application" and the latter is for "test check, on failure either
terminate or just mark the testcase as failed".  For QEMU, g_assert()
is always fatal, so code can assume that if the assertion fails
execution does not proceed, but this is not true of g_assert_true().

In npcm7xx_pwm-test, the pwm_index() and pwm_module_index() functions
include some assertions that are just guarding against possible bugs
in the test code that might lead us to out-of-bounds array accesses.
These should use g_assert() because they aren't part of what the test
is testing and the code does not correctly handle the case where the
condition was false.

This fixes some Coverity issues where Coverity knows that
g_assert_true() can continue when the condition is false and
complains about the possible array overrun at various callsites.
