[PATCH 0/7] testing/next: gdb-multiarch, check-tcg, vbsa tests

[Alex Bennée]

This is the current status of my testing tree. The gdb-multiarch and
filtering changes should be pretty uncontroversial. Due to the
enhancements I needed to make to get the vbsa linux tests running they
may want to cook a bit longer and wait until the 11.0 release is out
of the way.

Please review

Alex.

[PATCH 2/7] tests/tcg: allow filtering of TCG tests

[Alex Bennée]

We have a lot of TCG tests now which can be fiddly if we just want to
check one particular test type across the targets. Introduce
TCG_TEST_FILTER to allow this:

  make check-tcg TCG_TEST_FILTER=gdb

to run all the gdb tests across the suites.

[PATCH 3/7] tests/tcg/multiarch/linux-test: use portable alternative for dirent64

[Alex Bennée]

From: Matheus Tavares Bernardino <matheus.bernardino@oss.qualcomm.com>

dirent64 and readdir64 are glibc-specific and not portable to other
C libraries such as musl. Define _FILE_OFFSET_BITS=64 instead, which
portably instructs all libc implementations to use 64-bit file offsets,
making readdir() and struct dirent equivalent to their 64-bit variants.

[PATCH 7/7] tests/functional: add VBSA linux tests

[Alex Bennée]

This extends the VBSA test to run the linux tests. The sysarch-acs
test suite does provide some pre-built images which is good because
the tests require a patched kernel. However due to the structure of
the image we need to jump one or two hoops to get something useful:

  - download and double decompress (zip then xz) the image
  - navigate grub to launch the Linux Execution Environment
  - shutdown the system once tests are done
  - extract the logs from the MSDOS file system and parse them

It does make the code a bit ugly but it works for me at least. So far
the subset of tests run is limited but that might be solved by adding
some more devices to the PCIe bus to exercise the SMMU behaviour.

If you run "make help" in one of the TCG test dirs you will get a list:

I think you should rather use archive_extract() instead of uncompress() for 
zip files, shouldn't you? ... and if I've got that right, support for zip is 
already included in there.

Yes, but I was more thinking at something from the top, without needing

To add more information, we tested it on GitHub, our machines and 
GitLab, and for an unknown reason, it only fails on GitLab runners.

Which is unfortunate since it is where QEMU run its CI.

Also we tested on our local Linux machines, where this test pass

FWIW it passes on my laptop as well.

Does this test fail only for hppa, or for other architectures as well?

I'm asking because it may have something to do with /proc/self/mem or 
with the architecture.

So at least Alpha / ARM / Aarch64 / HPPA.

(I haven't checked whether the test is run for other targets).

We also run these on GitHub runners where the tests pass, and apparently
when running on k8s private runner on GitLab they also pass. The problem
is with public runner on GitLab.
