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
