[PATCH] sched/deadline: Unthrottle PI boosted threads while enqueuing

2020-09-16 Thread Daniel Bristot de Oliveira
stress-ng has a test (stress-ng --cyclic) that creates a set of threads under SCHED_DEADLINE with the following parameters: dl_runtime = 1 (10 us) dl_deadline = 10 (100 us) dl_period= 10 (100 us) These parameters are very aggressive. When using a system without HRT
