It's huge, complex, and I never can get it working. I did the following: # lkp split-job jobs/perf-sanity-tests.yaml # lkp install -f ./perf-sanity-tests-defaults.yaml [ had to fix python up a little because it wanted python3.9 where I had 3.13 ] # lkp run ./perf-sanity-tests-defaults.yaml /work/git/lkp-tests.git/programs/perf-sanity-tests/run: 7: .: cannot open /work/git/lkp-tests.git/lib/tests/perf_test.sh: No such file kill 37975 vmstat --timestamp -n 10 kill 37973 dmesg --follow --decode wait for background processes: 37978 meminfo I have no idea where this "perf_test.sh" is supposed to come from, and why it doesn't exist :-p -- Steve
