![]() Especially when CONFIG_LOCKDEP and other debug configs are enabled,
Perf can print the following warning when running the "kernel lock
contention analysis" test:
Warning:
Processed 1378918 events and lost 4 chunks!
Check IO/CPU overload!
Warning:
Processed 4593325 samples and lost 70.00%!
The test already supplies -q to run in quiet mode, so extend quiet mode
to perf_stdio__warning() and also ui__warning() for consistency.
This fixes the following failure due to the extra lines counted:
perf test "lock cont" -vvv
82: kernel lock contention analysis test :
--- start ---
test child forked, pid 3125
Testing perf lock record and perf lock contention
[Fail] Recorded result count is not 1: 9
test child finished with -1
---- end ----
kernel lock contention analysis test: FAILED!
