Currently, BTF tests fail constantly, this series fixes two major reasons
why they fail, and makes the error messages acquired when using '-vv'
more verbose, so when they fail, one can easily diagnose the problem.
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 783533
Checking if vmlinux exists
Tracing syscall landlock_add_rule
Tracing non-syscall tracepoint syscall
---- 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 851658
Checking if vmlinux exists
Tracing syscall landlock_add_rule
Tracing non-syscall tracepoint timer:hrtimer_setup,timer:hrtimer_start
[tracepoint failure] Failed to trace tracepoint timer:hrtimer_setup,timer:hrtimer_start, 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!
Changes in v3:
- Change the regex pattern in struct augmentation (Ian)
Changes in v2:
- Add an extra newline after error messages
- Rename the title of patch 3 to 'Stop tracing hrtimer_setup...'
- Take the debug diff for explanation out of patch 5 to make it apply
normally
- Add base-commit in this cover letter
Howard Chu (6):
perf test trace: Use shell's -f flag to check if vmlinux exists
perf test trace: Remove set -e and print trace test's error messages
perf test trace: Stop tracing hrtimer_setup event in trace enum test
perf test trace: Remove set -e for BTF general tests
perf test trace BTF: Use --sort-events in BTF general tests
perf test trace BTF: Change the regex pattern in the struct test
