selftests/ftrace: Reduce trace buffer checking overhead

2017-06-07T16:07:22+00:00

Current event/toplevel-enable.tc checking the trace buffer by dumping all events while recording events. However, this makes system very busy. To reduce this overhead comes from reading trace buffer and recording trace buffer, use head instead of cat and stop tracing while reading. Signed-off-by: Masami Hiramatsu Signed-off-by: Shuah Khan

selftests: ftrace: Have event tests also run in an tracing instance

2017-04-26T12:54:32+00:00

The ftrace selftests of events: event-enable, event-pid, and subsystem-enable can all be run inside an instance. Change their tests to do both a toplevel run an an instance run. Acked-by: Masami Hiramatsu Acked-by: Namhyung Kim Signed-off-by: Steven Rostedt (VMware)

kselftests/ftrace: Add a test case for event pid filtering

2016-05-16T15:02:03+00:00

Check event is filtered by set_event_pid and options/event-fork. Signed-off-by: Namhyung Kim Signed-off-by: Shuah Khan

ftracetest: Do not use usleep directly

2015-04-03T15:16:32+00:00

The usleep is only provided on distros from Redhat so running ftracetest on other distro resulted in failures due to the missing usleep. The reason of using [u]sleep in the test was to generate (scheduler) events. It can be done various ways like this: yield() { ping localhost -c 1 || sleep .001 || usleep 1 || sleep 1; } For more information to the history of this patch, please refer to: Link: http://lkml.kernel.org/r/1427329943-16896-1-git-send-email-namhyung@kernel.org Reported-by: Michael Ellerman Reported-by: Dave Jones Reported-by: Luis Henriques Suggested-by: Pádraig Brady Acked-by: Steven Rostedt Acked-by: Masami Hiramatsu Signed-off-by: Namhyung Kim Signed-off-by: Shuah Khan

ftracetest: Convert exit -1 to exit $FAIL

2015-03-31T16:15:46+00:00

POSIX says that exit takes an unsigned integer between 0 and 255, so using -1 doesn't work on POSIX shells. There is already a well-defined failure code, $FAIL (1), so use that. Signed-off-by: Michael Ellerman Acked-by: Steven Rostedt Signed-off-by: Shuah Khan

ftracetest: Add basic event tracing test cases
