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].

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