721a1f53df perf tests: Pass the subtest index to each test routine
Some tests have sub-tests we want to run, so allow passing this.

Wang tried to avoid having to touch all tests, but then, having the
test.func in an anonymous union makes the build fail on older compilers,
like the one in RHEL6, where:

  test a = {
	.func = foo,
  };

fails.

To fix it leave the func pointer in the main structure and pass the subtest
index to all tests, end result function is the same, but we have just one
function pointer, not two, with and without the subtest index as an argument.

2690c73093 perf test: Suppress libtraceevent warnings
Currently libtraceevent emits warning on unsupported event formats.
However it'd be better to see them only -v option is given.  To do that,
it needs to override the warning() function which is used in the
libtracevent.  Thus add set_warning_routine() same as set_die_routine()
and check the verbose flag in our warning routine.

Before:
  # perf test 5
   5: parse events tests                                       :
    Warning: [kvmmmu:kvm_mmu_get_page] bad op token {
    Warning: [kvmmmu:kvm_mmu_sync_page] bad op token {
    Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token {
    Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token {
    Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined
    ...
   Ok

After:
  # perf test 5
   5: parse events tests                                       : Ok

ee4c75887d perf tools: Force period term to overload global settings
Currently the command line option settings beats the per event period
settings:

With no global settings, we get per-event configuration:

  $ perf record -e 'cpu/instructions,period=20000/' sleep 1
  $ perf evlist -v
  ... { sample_period, sample_freq }: 20000 ...

With 'c' option period setup, we get 'c' option value:
  $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
  $ perf evlist -v
  ... { sample_period, sample_freq }: 1000 ...

This patch makes the per-event settings overload the global 'c' option
setup:

  $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
  $ perf evlist -v
  ... { sample_period, sample_freq }: 20000 ...

I think the making the per-event settings to overload any other config
makes more sense than current state. However it breaks the current
'period' term handling, which might cause some noise.. so let's see ;-).

Also fixing parse event tests with the new behaviour.

43f322b4ab perf tests: Switch from open to openat
Multiple perf tests fail on arm64 due to missing open syscall:

 2: detect open syscall event                              : FAILED!

open(2) is a legacy syscall, replaced with openat(2) since 2.6.16.  Thus
new architectures in kernel, such as arm64, don't implement these legacy
syscalls.

The patch replaces all sys_enter_open events with sys_enter_openat,
renames the related tests and test output to avoid confusion.

b39b839309 perf tools: Add parse_events_error interface
Adding support to return error information from parse_events function.
Following struct will be populated by parse_events function on return:

  struct parse_events_error {
    int   idx;
    char *str;
    char *help;
  };

where 'idx' is the position in the string where the parsing failed,
'str' contains dynamically allocated error string describing the error
and 'help' is optional help string.

The change contains reporting function, which currently does not display
anything. The code changes to supply error data for specific event types
are coming in next patches. However this is what the expected output is:

  $ sudo perf record -e 'sched:krava' ls
  event syntax error: 'sched:krava'
                       \___ unknown tracepoint
  ...

  $ perf record -e 'cpu/even=0x1/' ls
  event syntax error: 'cpu/even=0x1/'
                           \___ unknown term

  valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2,name,period,branch_type
  ...

  $ perf record -e cycles,cache-mises ls
  event syntax error: '..es,cache-mises'
                                 \___ parser error
  ...

The output functions cut the beginning of the event string so the error
starts up to 10th character and cut the end of the string of it crosses
the terminal width.

ffe59788e6 perf test: Add test case for pmu event new style format
Add test case in automated tests suite. It checks not only the two types
of pmu event stytle formats "pmu_event_name" and "cpu/pmu_event_name/",
but also the different formats mixtures which are more likely to trigger
parse issue.

The patch set including this one has been tested by the perf automated
test:

   ./perf test parse -v"

On haswell, ivybridge and Romley platform.

The patch set also has been tested on haswell by the following script.

Note: please make sure that your test system support TSX and
L1-dcache-loads events. Otherwise, you may want to change the events to
other pmu events.

  [lk@localhost ~]$ cat perf_style_test.sh
  # hardware events + kernel pmu event with different style
  perf stat -x, -e cycles,mem-stores,tx-start sleep 2
  perf stat -x, -e cpu-cycles,cycles-ct,cycles-t sleep 2
  perf stat -x, -e cycles,cpu/cycles-ct/,cpu/cycles-t/ sleep 2
  perf stat -x, -e instructions,cpu/tx-start/ sleep 2
  perf stat -x, -e '{cycles,tx-start}' sleep 2
  perf stat -x, -e '{cycles,cpu/tx-start/}' sleep 2

  # HW Cache event + kernel pmu event with different style

  perf stat -x, -e L1-dcache-loads,mem-stores,cpu/tx-start/ sleep 2
  perf stat -x, -e '{L1-dcache-loads,mem-stores}' sleep 2

615b8f99f7 perf tests: Add numeric identifier to evlist_test
In tests/parse-events.c test cases are declared in evlist_test[]
arrays. Elements of arrays are initialized in following pattern:
	[i] = {
 		.name  = ...,
 		.check = ...,
 	},

When perf-test is running with '-v' option, 'i' variable will be
printed for every existing test.

However, we can't add any arch specific tests inside #ifdefs, because it
will create collision between the element number inside #ifdef and the
next one outside.

This patch adds 'id' field in evlist_test, uses it as a test
identifier and removes explicit numbering of array elements. This helps
to number tests with gaps.

553873e1df tools/: Convert to new topic libraries
Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.

For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.

acme:

"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.

But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

Fixup documentation cleaning target while at it.

cf38fadade perf fs: Rename NAME_find_mountpoint() to NAME__mountpoint()
Shorten it, "finding" it is an implementation detail, what callers want
is the pathname, not to ask for it to _always_ do the lookup.

And the existing implementation already caches it, i.e. it doesn't
"finds" it on every call.

Convert perf_evsel__is_group_member to perf_evsel__is_group_leader.
This is because the most usecases are using negative form to check
whether the given evsel is a leader or not and it's IMHO somewhat
ambiguous - leader also *is* a member of the group.
