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
25 **-t**, **--trace** \[*file*]
29 **--dma-latency** *us*
30         Set the /dev/cpu_dma_latency to *us*, aiming to bound exit from idle latencies.
31         *cyclictest* sets this value to *0* by default, use **--dma-latency** *0* to have
34 **-k**, **--kernel-threads**
36         Use timerlat kernel-space threads, in contrast of **-u**.
38 **-u**, **--user-threads**
40         Set timerlat to run without a workload, and then dispatches user-space workloads
42         adding so the measurement for the kernel-to-user and user-to-kernel to the tracer
43         output. **--user-threads** will be used unless the user specify **-k**.
45 **-U**, **--user-load**
47         Set timerlat to run without workload, waiting for the user to dispatch a per-cpu
49         See linux/tools/rtla/sample/timerlat_load.py for an example of user-load code.
