Lines Matching +full:exit +full:- +full:latency +full:- +full:us

1 **-a**, **--auto** *us*
4         while debugging the system. It is equivalent to use **-T** *us* **-s** *us*
5         **-t**. By default, *timerlat* tracer uses FIFO:95 for *timerlat* threads,
6         thus equilavent to **-P** *f:95*.
8 **-p**, **--period** *us*
12 **-i**, **--irq** *us*
14         Stop trace if the *IRQ* latency is higher than the argument in us.
16 **-T**, **--thread** *us*
18         Stop trace if the *Thread* latency is higher than the argument in us.
20 **-s**, **--stack** *us*
22         Save the stack trace at the *IRQ* if a *Thread* latency is higher than the
23         argument in us.
25 **--dma-latency** *us*
26         Set the /dev/cpu_dma_latency to *us*, aiming to bound exit from idle latencies.
27         *cyclictest* sets this value to *0* by default, use **--dma-latency** *0* to have
30 **-u**, **--user-threads**
32         Set timerlat to run without a workload, and then dispatches user-space workloads
34         adding so the measurement for the kernel-to-user and user-to-kernel to the tracer
