maybe that is already useful for the needed additional > debugging information? I did not know that script, thanks. It shows more than this patch does. The two lines are there for the selftests. params_waking and random_mix of deadline_bw_test read running_bw and this_bw of each CPU from /sys/kernel/debug/sched/debug. A selftest cannot rely on drgn and on the debug information of the running kernel. So I would keep the patch as it is. I would not add extra_bw: no test reads it, and your script has it.
