17a2634bcb perf test: Ignore .scale and other special files 
'perf test' tries to parse all entries in /sys/devices/cpu/events/.
Ignore the special entries like '.scale', which cannot be directly
parsed as an event. This patch assumes all files containing a '.' are
special and can be ignored.

43d0b97817 perf tools: Enable config and setting names for legacy cache events 
This patch allows setting config terms for legacy cache events.
For example:

  # perf stat -e L1-icache-misses/name=valA/ -e branches/name=valB/ ls
  ...
   Performance counter stats for 'ls':

              11299      valA
             451605      valB

        0.000779091 seconds time elapsed

  # perf record -e cache-misses/name=inh/ -e cache-misses/name=noinh,no-inherit/ bash
  # ls
  # exit
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.023 MB perf.data (131 samples) ]
  # perf report --stdio | grep -B 1 'Event count'
  # Samples: 105  of event 'inh'
  # Event count (approx.): 109118
  --
  # Samples: 26  of event 'noinh'
  # Event count (approx.): 48302

A test case is introduced to test this feature.

10bf358a1b perf tools: Enable config raw and numeric events 
This patch allows setting config terms for raw and numeric events.
For example:

  # perf stat -e cycles/name=cyc/ ls
  ...
  1821108      cyc
  ...

  # perf stat -e r6530160/name=event/ ls
  ...

  ...

  # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
  ...
  # perf report --stdio
  ...
  # Samples: 124  of event 'cycles'

  ...
  # Samples: 91  of event 'evtx'
  ...
  93.76%     0.00%  swapper      [kernel.vmlinux]            [k] cpu_startup_entry
          |
          ---cpu_startup_entry
             |
             |--66.63%--call_cpuidle
             |          cpuidle_enter
             |          |
  ...

3 test cases are introduced to test config terms for symbol, raw and
numeric events.

Committer note:

Further testing shows that we can retrieve the event name using 'perf
evlist -v' and looking at the 'config' perf_event_attr field, i.e.:

  # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 1.724 MB perf.data (2076 samples) ]
  # perf evlist
  cycles
  evtx
  # perf evlist -v
  cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1

In these two cases, a 'perf test' entry and in the PMU code the
list_head is on the stack, so we can't use perf_event__free_terms()

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

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.
