Adding periods to SCHED_DEADLINEAdding periods to SCHED_DEADLINEPosted Jul 21, 2010 16:18 UTC (Wed) by cesarb (subscriber, #6266)In reply to: Adding periods to SCHED_DEADLINE by abacus Parent article: Adding periods to SCHED_DEADLINE
It would be cool if people could "record" a trace of their scheduling so that the sched maintainers could "replay" it, so that they can find and fix bugs without having to find a reproducible testcase (i.e. even if it happened just once, if you have a trace, it could be used to find the cause).
I do not know if this already exists; I have not looked.

I believe "perf sched record" and "perf sched replay" will do exactly that.
