It is a very good idea to run LTP. How can it be extended to be run with
more CPU architecture ? To run some wider set of tests ?

The primary intent of this test is to check the Buildroot package recipe
is able to compile the ltp-testsuite correctly and install it on target
properly to be functional. It will be also useful when updating the
package.
This is for this reason I propose only one architecture (the default
armv5), with a very limited test set, to make sure compilation and
execution will be fast.
Conversely, this test is NOT aiming to fully test a given Kernel
version on Qemu. Buildroot is already testing that qemu_*_defconfig
are booting and reaching the user-space login.
What did you have in mind exactly? Testing more extensively a
specific defconfig? This could be done outside the Buildroot Gitlab CI,
for example, by a defconfig maintainer?
Best regards,
Julien.

OK, it did not inderstand that it was the primary intend. I was guessing
that the intends were to have a broader LTP scope of tests.

I understand your point. We can limit the time allocated to running the Buildroot
test suite, while LTP+Buildroot could be managed as a separate GitLab CI/project.
So the current proposal for LTP check is OK.

While this above is OK, some notes:
1) Many LTP tests require LTPROOT environment variable (to access some data files),
e.g.:
export LTPROOT="/usr/lib/ltp-testsuite"
See https://linux-test-project.readthedocs.io/en/latest/users/setup_tests.html
It looks to me that infra.emulator.Emulator does not support inserting
environment variables via os.environ.
2) runltp old script has been deprecated, kirk is the replacement:
https://github.com/linux-test-project/kirk
Currently kirk supports few testing frameworks: LTP, kselftests and liburing.
While kirk can be run o SUT (like runltp), the best usage is to run it on the
host. It supports testing via starting QEMU VM, SSH and not yet stable LTX
backend.
Due the above I'd like to add kirk host package to Buildroot.
Kind regards,

Since only a limited set of tests are run, it's apparently not needed.

No, the environment can be set as part of the command itself:
cmd = ("LTPROOT='...' "
"/usr/lib/ltp-testsute/runltp "
...
)
> 2) runltp old script has been deprecated, kirk is the replacement:
Ah, annoying. I think we'd probably prefer to run some tests directly then,
without runltp at all. The point of this test is not to run the actual LTP
tests, but just to verify that ltp-testsuite has been installed correctly.

Starting via Qemu is possibly annoying because then we no longer control how
QEMU is booted. SSH could be interesting, but currently the image doesn't have
an SSH server by default. So I think running kirk in the test environment
directly is probably the easiest for us.
