Description: Test module to create a preempt / IRQ disable delay thread to test latency tracers
More info: Select this option to build a test module that can help test latency tracers by executing a preempt or irq disable section with a user configurable delay. The module busy waits for the duration of the critical section. For example, the following invocation generates a burst of three irq-disabled critical sections for 500us: modprobe preemptirq_delay_test test_mode=irq delay=500 burst_size=3 What's more, if you want to attach the test on the cpu which the latency tracer is running on, specify cpu_affinity=cpu_num at the end of the command. If unsure, say N
