Testresults

RTAI testsuite

UP scheduler - latency

The difference in time between the expected switch time and the time when a task is actually called by the scheduler is measured. For this test the RTAI UP scheduler is used.

LXRT scheduler - latency

The difference in time between the expected switch time and the time when a task is actually called by the scheduler is measured. For this test the RTAI LXRT scheduler is used.

UP scheduler - preemption

The following table shows the results of a stress test aimed at verifying that the schedulers preempt well under intense load. It is a simple test that combines the latency calibration task with a fast and slow task in such a way to have two levels of preemption, nesting on an odd number of tasks. It shows the maximum jitter of the fast task, which has the second highest priority, and of the slow which has the lowest priority. Reasonable jitters are a clear indication of preemption.
