| |
The dynamic entry is created for each field in a tracepoint event. Since they have no fixed hpp format index, it should skip when perf_hpp__reset_width() is called.
This caused following assertion failure..
$ perf record -e sched:sched_switch -a sleep 1
$ perf report -s comm,next_pid --stdio perf: ui/hist.c:651: perf_hpp__reset_width: Assertion `!(fmt->idx >= PERF_HPP__MAX_INDEX)' failed.
