perf test: Parse events break apart tests

2022-05-23T13:04:59+00:00

Break multiple tests in the main test into individual test cases. Make
better use of skip and add reasons. Skip also for parse event permission
issues (detected by searching the error string). Rather than break out
of tests on the first failure, keep going and logging to pr_debug.

2022-05-23T13:04:55+00:00

Remove two unused variables. Make structs const. Also fix the array
index (aka id) for the event software/r0x1a/.

perf test: Add parse-events test for aliases with hyphens

2022-01-22T20:21:41+00:00

Add a test which allows us to test parsing an event alias with hyphens.

Since these events typically do not exist on most host systems, add the
alias to the fake pmu.

Function perf_pmu__test_parse_init() has terms added to match known test
aliases.

perf test: Move each test suite struct to its test

2021-11-13T13:30:58+00:00

Rather than export test functions, export the test struct. Rename with a
suite__ prefix to avoid name collisions.

Committer notes:

Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when
cross building to arm (32-bit).

perf parse-event: Add init and exit to parse_event_error

2021-11-07T18:39:25+00:00

parse_events() may succeed but leave string memory allocations reachable
in the error.

Add an init/exit that must be called to initialize and clean up the
error. This fixes a leak in metricgroup parse_ids.

perf parse-events: Set numeric term config

2021-09-28T19:14:05+00:00

For numeric terms, the config field may be NULL as it is not set from
the l+y parsing.

Fix by setting the term config from the term type name.

Also fix up the pmu-events test to set the alias strings to set the
period term properly, and fix up parse-events test to check the term
config string.

perf tests: Add test for PMU aliases

2021-09-03T11:38:49+00:00

A perf uncore PMU may have two PMU names, a real name and an alias.

Add one test case to verify that the real and alias names have the same
effect.

Iterate sysfs to get one event which has an alias and create an evlist
by adding two evsels. Evsel1 is created by event and evsel2 is created
by alias.

Test asserts:

  evsel1->core.attr.type == evsel2->core.attr.type
  evsel1->core.attr.config == evsel2->core.attr.config
