7 # USAGE: funclatency [-h] [-p PID] [-i INTERVAL] [-T] [-u] [-m] [-F] [-r] [-v]
10 # Run "funclatency -h" for full usage.
34 ./funclatency do_sys_open # time the do_sys_open() kernel function
35 ./funclatency c:read # time the read() C library function
36 ./funclatency -u vfs_read # time vfs_read(), in microseconds
37 ./funclatency -m do_nanosleep # time do_nanosleep(), in milliseconds
38 ./funclatency -i 2 -d 10 c:open # output every 2 seconds, for duration 10s
39 ./funclatency -mTi 5 vfs_read # output every 5 seconds, with timestamps
40 ./funclatency -p 181 vfs_read # time process 181 only
