1f08c3bdfSopenharmony_ciTest: sched_jitter 2f08c3bdfSopenharmony_ci=================== 3f08c3bdfSopenharmony_ciThis test measures scheduling jitter w/ realtime processes. 4f08c3bdfSopenharmony_ci 5f08c3bdfSopenharmony_ciIt spawns a realtime thread that repeatedly times how long it takes to do a 6f08c3bdfSopenharmony_cifixed amount of work. It then prints out the maximum jitter seen (longest 7f08c3bdfSopenharmony_ciexecution time - the shortest execution time). 8f08c3bdfSopenharmony_ci 9f08c3bdfSopenharmony_ciIt also spawns off a realtime thread of higher priority that simply wakes up 10f08c3bdfSopenharmony_ciand goes back to sleep. This tries to measure how much overhead the scheduler 11f08c3bdfSopenharmony_ciadds in switching quickly to another task and back. 12
