How to enable more tracers in ftrace
I have linux 2.6.30 running on ARM SMP board. I want to use ftrace for benchmarking.
I only see sched_switch in the /debug/tracing/available_tracers. I wonder how to enable other tracers, like function, wakeup, irqsoff, etc.
Should I modify .config file in order to enable them?
Thanks!
