perf test trace: Stop tracing hrtimer_setup event in trace enum test
The event 'timer:hrtimer_setup' is relatively new, for older kernels, perf trace enum tests won't run as the event 'timer:hrtimer_setup' cannot be found. It was originally called 'timer:hrtimer_init', before being renamed in: commit 244132c4e577 ("tracing/timers: Rename the hrtimer_init event to hrtimer_setup") Using timer:hrtimer_start should be enough for current testing, and hopefully 'start' won't be renamed in the future. Before: $ sudo /tmp/perf test enum -vv 107: perf trace enum augmentation tests: 107: perf trace enum augmentation tests : Running --- start --- test child forked, pid 786187 Checking if vmlinux exists Tracing syscall landlock_add_rule Tracing non-syscall tracepoint timer:hrtimer_setup,timer:hrtimer_start [tracepoint failure] Failed to trace timer:hrtimer_setup,timer:hrtimer_start tracepoint, output: event syntax error: 'timer:hrtimer_setup,timer:hrtimer_start' \___ unknown tracepoint Error: File /sys/kernel/tracing//events/timer/hrtimer_setup not found. Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?. Run 'perf list' for a list of valid events Usage: perf trace [<options>] [<command>] or: perf trace [<options>] -- <command> [<options>] or: perf trace record [<options>] [<command>] or: perf trace record [<options>] -- <command> [<options>] -e, --event <event> event/syscall selector. use 'perf list' to list available events ---- end(-1) ---- 107: perf trace enum augmentation tests : FAILED! After: $ sudo /tmp/perf test enum -vv 107: perf trace enum augmentation tests: 107: perf trace enum augmentation tests : Running --- start --- test child forked, pid 808547 Checking if vmlinux exists Tracing syscall landlock_add_rule Tracing non-syscall tracepoint timer:hrtimer_start ---- end(0) ---- 107: perf trace enum augmentation tests : Ok Signed-off-by: Howard Chu <[email protected]> Tested-by: Namhyung Kim <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Namhyung Kim <[email protected]>
