This mode sets some commonly used options - while debugging the system. It is equivalent to use **-T** *us* **-s** *us* - **-t**. By default, *timerlat* tracer uses FIFO:95 for *timerlat* threads, - thus equilavent to **-P** *f:95*. - -**-p**, **--period** *us* - - Set the *timerlat* tracer period in microseconds. - -**-i**, **--irq** *us* - - Stop trace if the *IRQ* latency is higher than the argument in us. - -**-T**, **--thread** *us* - - Stop trace if the *Thread* latency is higher than the argument in us. - -**-s**, **--stack** *us* - - Save the stack trace at the *IRQ* if a *Thread* latency is higher than the - argument in us. - -**--dma-latency** *us* - Set the /dev/cpu_dma_latency to *us*, aiming to bound exit from idle latencies. - *cyclictest* sets this value to *0* by default, use **--dma-latency** *0* to have - similar results. - -**-u**, **--user-threads** - - Set timerlat to run without a workload, and then dispatches user-space workloads - to wait on the timerlat_fd. Once the workload is awakes, it goes to sleep again - adding so the measurement for the kernel-to-user and user-to-kernel to the tracer - output. |
