Various tests and data captures used in debugging real-time latency regressions.
- config - kernel configs used.
- cyclictest_deferred_timer_load - cyclictest results with hrtimer load when deferring non-rt timers to softirq.
- cyclictest_hackb_iperf_load - cyclictest results with hackbench + iperf load.
- cyclictest_timer_load - cyclictest results with hrtimer load.
- hack - quick hack patch to allow deferring non-rt hrtimers to softirq.
- timer-stress - hrtimer load using a clock_nanosleep()/clock_gettime() stress test.
- traces - kernel traces showing latency regressions when timers get stacked.
