Add -e/--event option. This option enables an event in the trace (-t) session. The argument can be a specific event, e.g., -e sched:sched_switch, or all events of a system group, e.g., -e sched. Multiple -e are allowed. It is only active when -t or -a are set. This option is available for all current tools.

|
|
|
- *o:prio* - use SCHED_OTHER with *prio*;
|
|
- *r:prio* - use SCHED_RR with *prio*;
|
|
- *f:prio* - use SCHED_FIFO with *prio*;
|
|
- *d:runtime[us|ms|s]:period[us|ms|s]* - use SCHED_DEADLINE with *runtime* and *period* in nanoseconds.
