Pull tracing fixes from Steven Rostedt:
 "Masami had a couple more fixes to the synthetic events. One was a
  proper error return value, and the other is for the self tests"

selftests/ftrace: Fix synthetic event test to delete event correctly

2018-10-28T19:14:55+00:00

Fix the synthetic event test case to remove event correctly.
If redirecting command to synthetic_event file without append
mode, it cleans up all existing events and execute (parse) the
command. This means "delete event" always fails to find the
target event.

Since previous synthetic event has a bug which doesn't return
-ENOENT even if it fails to find the deleting event, this test
passed. But fixing that bug, this test fails because this test
itself has a bug.

This fixes that bug by trying to delete event right after
adding an event, and use append mode redirection ('>>') instead
of normal redirection ('>').

selftests/ftrace: Use loopback address instead of localhost

2018-10-24T20:49:35+00:00

Use raw loopback address instead of localhost, because
"localhost" can depend on nsswitch and in some case
we can not resolve the localhost.

selftests/ftrace: Remove unneeded per-test init/cleanup ftrace

2018-10-24T20:49:35+00:00

Since ftracetest framework calls initialize_ftrace() right before
each test and after all tests, we don't need to init/cleanup
ftrace for each test case.
Just remove such unneeded init/cleanup code because it can
increase logfile size.

tracing/selftest: Add test to test simple snapshot trigger for trace_marker

2018-06-04T21:28:01+00:00

Several complex trigger tests were added for trace_marker, but not a simple
one. This could be used to help diagnose a problem with the code by giving a
reference between how complex a trigger is that fails.

tracing/selftest: Add test to test hist trigger between kernel event and trace_marker

2018-05-29T12:30:01+00:00

Add a test that tests a trigger that is initiated by a kernel event
(sched_waking) and compared to a write to the trace_marker.

tracing/selftest: Add selftests to test trace_marker histogram triggers

2018-05-29T12:29:54+00:00

Add a couple of tests that test the trace_marker histogram triggers.
One does a straight histogram test, the other will create a synthetic event
and test the latency between two different writes (using filters to
differentiate between them).

selftests: ftrace: Add a testcase for multiple actions on trigger

2018-04-25T14:28:36+00:00

Add a testcase for multiple actions with different
parameters on an event trigger, which has been fixed
by commit 192c283e93bd ("tracing: Add action comparisons
 when testing matching hist triggers").
