Hi Steven,
I managed to build task state char map dynamically by parsing
the tracepoint print format from data recorded by perf. And
likewise for libtraceevent.
FYI, I tried TEP_PRINT_INFO but no shot. It turns out TEP_PRINT_INFO
stills relies on libtraceevent (i.e., sched_switch_handler() in
plugin_sched_switch.c) and we need to parse the print format on our own.
Anyway, it works now and I've tested on some perf.data in old formats
but not cover all the kernel releases.
Thoughts?
Regards,
Ze
