Hm, interesting problem. rocm-test-launcher was designed to be a helper
for tests driven by the autopkgtest command, rather than being invoked
directly. Among other things, the utility checks for GPU presence only
so that it can skip, rather than error out, on a lack thereof, which is
what needs to happen in the official CI (as opposed to [1]).
I saw GPU selection as part of the testbed setup. To this end, packages
'rocm-qemu-support' and 'rocm-podman-support' provide suitable
autopkgtest backends [2, 3].
Given the above, adding this feature to rocm-test-launcher would seem
like a layer violation, so Cory's intuition was right.
However, it also shouldn't be needed. When designing tests, if you want
to run them in your shell, you might as well invoke the tests directly,
ie:
OCL_ICD_VENDORS=/etc/OpenCL/vendors/amdocl64.icd debian/tests/script*
And in d/tests/control, you would just use
rocm-test-launcher debian/tests/script*
and you could rely on the fact that our team's CI [1] provides properly
set up testbeds.
Side note: The synopsis of rocm-test-launcher is
rocm-test-launcher CMD [ARGS]
so if your intention was for debian/tests/script* to expand to multiple
tests, you'll need to invoke rocm-test-launcher for each of them, or
create a small wrapper like this one [4].

Thanks. In any case, I'm subscribed to the list :)
Best,

[1]: https://ci.rocm.debian.net
[2]: For example, with the 'qemu+rocm' backend, you could run an
autopkgtest with the one GPU in PCI slot 09:00.0 like so:
$ autopkgtest -B <package> -- qemu+rocm --gpu 09:00.0 <img>
[3]: Sadly, after much trying, it seems that the analog for [1] in
rootless containers, using the 'podman+rocm' backend, is not
possible due to come cgroupsv2 restriction. However, I still
have the code for that, and I guess I could ship it for people who
want to try it in rootful containers.
