selftests/ftrace: fix dynamic_events dependency check

2022-10-18T20:27:23Z

commit 95c104c378dc ("tracing: Auto generate event name when creating a group of events") changed the syntax in the ftrace README file which is used by the selftests to check what features are support. Adjust the string to make test_duplicates.tc and trigger-synthetic-eprobe.tc work again.

selftests/ftrace: Add selftest for testing eprobe events on synthetic events

2021-08-21T14:25:34Z

Add a test to test event probes, by creating a synthetic event across sys_enter_openat and sys_exit_openat that passes the filename pointer from the enter of the system call to the exit, and then add an event probe to the synthetic event to make sure that the file name is seen.

selftests/ftrace: Add '!event' synthetic event syntax check

2021-02-11T21:22:32Z

Add a check confirming that '!event' alone will remove a synthetic event. Link: https://lkml.kernel.org/r/1dff3f03d18542cece08c10d6323d8a8dba11e42.1612208610.git.zanussi@kernel.org Signed-off-by: Tom Zanussi Signed-off-by: Steven Rostedt (VMware)

selftests/ftrace: Update synthetic event syntax errors

2021-02-11T21:22:20Z

Some of the synthetic event errors and positions have changed in the code - update those and add several more tests. Also add a runtime check to ensure that the kernel supports dynamic strings in synthetic events, which these tests require.

selftests/ftrace: Add test case for synthetic event syntax errors

2020-10-15T16:01:13Z

Add a selftest that verifies that the syntax error messages and caret positions are correct for most of the possible synthetic event syntax error cases.

selftests/ftrace: Change synthetic event name for inter-event-combined test

2020-10-15T16:01:13Z

This test uses waking+wakeup_latency as an event name, which doesn't make sense since it includes an operator. Illegal names are now detected by the synthetic event command parsing, which causes this test to fail. Change the name to 'waking_plus_wakeup_latency' to prevent this.

selftests/ftrace: Add test case for synthetic event dynamic strings

2020-10-08T19:28:41Z

Add a selftest that defines and traces a synthetic event that uses a dynamic string event field. Link: https://lkml.kernel.org/r/74445afb005046d76d59fb06696a2ceaa164dec9.1601848695.git.zanussi@kernel.org Acked-by: Masami Hiramatsu Signed-off-by: Tom Zanussi Signed-off-by: Steven Rostedt (VMware)

selftests/ftrace: Support ":README" suffix for requires

2020-06-16T16:42:47Z

Add ":README" suffix support for the requires list, so that the testcase can list up the required string for README file to the requires list. Note that the required string is treated as a fixed string, instead of regular expression. Also, the testcase can specify a string containing spaces with quotes.

selftests/ftrace: Convert required interface checks into requires list

selftests/ftrace: Distinguish between hist and synthetic event checks

2020-06-01T12:23:37Z

With synthetic events now a separate config item as a result of 'tracing: Move synthetic events to a separate file', tests that use both need to explicitly check for hist trigger support rather than relying on hist triggers to pull in synthetic events. Add an additional hist trigger check to all the trigger tests that now require it, otherwise they'll fail if synthetic events but not hist triggers are enabled.
