Hi,
I would like to understand how to interpret perf tool output such as
reporting output etc.
Specifically, I would like to understand how to understand the following
output I got from running my program
M sched:sched_switch
?
633K sched:sched_stat_wait
?
620K sched:sched_stat_sleep
?
2K sched:sched_stat_iowait
?
648K sched:sched_stat_runtime
?
72 sched:sched_process_fork
?
623K sched:sched_wakeup
?
4K sched:sched_migrate_task
?
?
My problem is, I see the ipc I am using takes long time but during this
capture the cpu idle time has been 98%. So I am wondering where have I gone
wrong?
Thank you,
Srinath
