Sometimes a test is problematic for some reason and one wants to skip it,
for instance:
[root@sandy ~]# perf test
1: vmlinux symtab matches kallsyms : Ok
2: detect open syscall event : Ok
3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok
5: parse events tests : Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: function is_writable_pte not defined
Segmentation fault (core dumped)
So now we can use -s/--skip while the problematic tests are being fixed,
allowing us to test all the other entries:
[root@sandy ~]# perf test -s 5
1: vmlinux symtab matches kallsyms : Ok
2: detect open syscall event : Ok
3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok
5: parse events tests : Skip (user override)
6: x86 rdpmc test : Ok
7: Validate PERF_RECORD_* events & perf_sample fields : Ok
8: Test perf pmu format parsing : Ok
9: Test dso data interface : Ok
10: roundtrip evsel->name check : Ok
11: Check parsing of sched tracepoints fields : Ok
12: Generate and check syscalls:sys_enter_open event fields: Ok
13: struct perf_event_attr setup : Ok
14: Test matching and linking mutliple hists : Ok
15: Try 'use perf' in python, checking link problems : Ok

Test can currently return one of 3 states: ok, fail, skip.
The ok and fail states are self-explanatory. The skip state means that
some of the conditions for running the test was not met, making it
impossible to even run the test. For instance, if the hardware doesn't
support the 'precise' level required by a test, it will be skipped.

Current perf test code tries to execute python version 2 in order to
test attributes on perf_event_open syscall. However it's not default
python version anymore a system can have python v3 only or v2 with a
different name (e.g. python2). So if there's no such python interpreter
with the name 'python', the test would fail like this (yes, it's
happened on my new archlinux laptop :).
13: struct perf_event_attr setup :sh: python: command not found
FAILED!
As we can pass name of the python interpreter on make, use it for

Adding event parsing test for '*:*' tracepoints. Checking the count
matches all the tracepoints available plus current standard tracepoint
perf_event_attr check.
This test exposes warnings from traceevent lib about not being able to
parse some tracepoints' format data. Exposing these messages in the

The test_attr infrastructure hooks on the sys_perf_event_open call,
checking if a variable is set and if so calling a function to intercept
calls and do the checking.
But both the variable and the function aren't on objects that are
linked on the python binding, breaking it:
# perf test -v 15
15: Try 'use perf' in python, checking link problems :
--- start ---
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /home/acme/git/build/perf//python/perf.so: undefined symbol: test_attr__enabled
---- end ----
Try 'use perf' in python, checking link problems: FAILED!
#
Fix it by moving the variable to one of the linked object files and
providing a stub for the function in the python.o object, that is only
linked in the python binding.
Now 'perf test' is happy again:
# perf test 15
15: Try 'use perf' in python, checking link problems : Ok

As they are used from diff and event group report, add a test case to
verify their behaviors.
In this test I made a fake machine and two evsel. Each evsel got 10
samples (so hist entries) - 5 are common and the rests are not. So
after hists__match() both of them will have 5 entries with pair set.
And the second evsel has a collapsed entry so that the total number is 9
- I made it in order to simulate more realistic case. Thus after
hists__link the first entry will have 14 entries - 5 are common (w/
pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the
second entry will have 9 entries all have its pair.

When mmaping multiple events we need to find the right evsel that
matches an event in the ring buffer.
For that we need to set the PERF_FORMAT_ID bit in
perf_event_attr.read_format so that when we read the event fds we get
that id to then hash it and be able later to use perf_evlist__id2evsel
to find the right evsel.
We also need to set the PERF_SAMPLE_ID bit in
perf_event_attr.sample_type to ask for that id to be stashed in each
sample, so that we can demux it.
So add a perf_evsel__set_sample_id() method to do those two things in
one operation.

Currently the record command sets all events initially as disabled.
There's non conditional perf_evlist__enable call, that enables all
events before we exec tracee program. That actually screws whole
enable_on_exec logic, because the event is enabled before the traced
program got executed.
What we actually want is:
1) For any type of traced program:
- all independent events and group leaders are disabled
- all group members are enabled
Group members are ruled by group leaders. They need to
be enabled, because the group scheduling relies on that.
2) For traced programs executed by perf:
- all independent events and group leaders have
enable_on_exec set
- we don't specifically enable or disable any event during
the record command
Independent events and group leaders are initially disabled
and get enabled by exec. Group members are ruled by group
leaders as stated in 1).
3) For traced programs attached by perf (pid/tid):
- we specifically enable or disable all events during
the record command
When attaching events to already running traced we
enable/disable events specifically, as there's no
initial traced exec call.
Fixing appropriate perf_event_attr test case to cover this change.

Recently I build perf and get a build error on builtin-test.c. The error is as
following:
$ make
CC perf.o
CC builtin-test.o
cc1: warnings being treated as errors
builtin-test.c: In function ‘sched__get_first_possible_cpu’:

This problem is introduced in 3e7c439a. CPU_ALLOC and related macros are
missing in sched__get_first_possible_cpu function. In 54489c18, commiter
mentioned that CPU_ALLOC has been removed. So CPU_ALLOC calls in this
function are removed to let perf to be built.

This time out of map.[ch] mostly, just code move plus a buch of 'self'
removal, using machine or machines instead.

Currently if there's 'Unsup' exception raised, we do not clean up the
temp directory. Solving this by adding 'finally' to make the cleanup in
any case.

Since we allow multiple values in event field assignment, there's no
need for 'optional' field.. old version removal leftover.
Adding some comments into attr.py script regarding the test event load.

Currently the 'watermark' field is coded as 'watermask'.
As the type is global through the framework and tests, the typo spawned
no error.

Changing WRITE_ASS macro per Namhyung's comments, so the main usage case
