Hi Steven
I would like to collect histograms from timerlat and osnoise tracers event, but I cannot collect them because they are not tracepoints but... tracer events. So...
# ls /sys/kernel/tracing/events/ftrace/timerlat/ format hist
no hist, filter, trigger files...
How hard would it be to enable histograms to the ftrace/osnoise and ftrace/timerlat events?
This will allow me to reduce the overhead of rtla timerlat and rtla osnoise tools...
Thanks in advance, Stephen! -- Denny
