I always ask myself how could I reproduce this on a slightly different machine.
This install step didn't work for me on my machine. OTAH, the following steps are working:
bin/lkp install ./jobs/reaim-micro-cyclic-lkp-hsw01.yaml bin/lkp split-job ./jobs/reaim-micro-cyclic-lkp-hsw01.yaml
bin/lkp run ./reaim-micro-cyclic-lkp-hsw01-300s-600-creat_clo.yaml
But when I do this, I only get the perf.data file for this specific testrun for the kernel I run right now.
What are the steps missing to create this list of diffs for the various counter values like 'reaim.child_utime'?
Thanks,
