This way we'll be able to pass more test specific parameters without having to change this function signature. Will be used by the upcoming 'shell tests', shell scripts that will call perf tools and check if they work as expected, comparing its effects on the system (think 'perf probe foo') the output produced, etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Thomas Richter <tmricht@linux.vnet.ibm.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-wq250w7j1opbzyiynozuajbl@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

* test__parse_no_sample_id_all - test parsing with no sample_id_all bit set.

*
|
|
* This function tests parsing data produced on kernel's that do not support the
|
|
* sample_id_all bit. Without the sample_id_all bit, non-sample events (such as
|
|
* mmap events) do not have an id sample appended, and consequently logic
|
|
* designed to determine the id will not work. That case happens when there is
|
|
* more than one selected event, so this test processes three events: 2
|
|
* attributes representing the selected events and one mmap event.
|
|
*
|
|
* Return: %0 on success, %-1 if the test fails.
