The default sefltests timeout is 45 seconds. If you run the kmod selftests on your own with say: ./tools/testings/selftests/kmod.sh Then the default timeout won't be in effect. I've never ran kmod selftests using the generic make wrapper (./tools/testing/selftests/run_kselftest.sh -s) util now that I have support for it on kdevops [0]. And with that the test is limitted to the default timeout which we quickly run into. Bump this up to what I see is required on 8GiB / 8 vcpu libvirt q35 guest as can be easily created now with kdevops. To run selftests with kdevops: make menuconfig # enable dedicated selftests and kmod test make make bringup make linux make selftests-kmod This ends up taking about 280 seconds now, give or take add 50 seconds more more and we end up with 350. Document the rationale.

Adding timeouts like this for individual tests increases the overall kselftest run-time. I am not in favor of adding timeouts. We have to find a better way to do this. thanks, -- Shuah
