perf subcmd: Create subcmd library

2015-12-17T17:27:14+00:00

Move the subcommand-related files from perf to a new library named
libsubcmd.a.

Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to
'exec-cmd.*' to be consistent with the naming of all the other files.

perf tools: Remove 'perf' from subcmd function and variable names

2015-12-17T00:34:28+00:00

In preparation for moving exec_cmd.c and run-command.c out of perf and
into a library, remove 'perf' from all the symbol names.

perf tests: Pass the subtest index to each test routine

2015-11-19T16:19:15+00:00

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.

perf test: Keep test result clean if '-v' not set

2015-11-03T14:45:40+00:00

According to [1], 'perf test' should avoid output too much information
if '-v' is not set, only 'Ok', 'FAIL' or 'Skip' need to be printed.

This patch removes several messages sent directly to stderr to make
the output clean.

Before this patch:

  # perf test dummy
  23: Test using a dummy software event to keep tracking       : (not supported) Ok

After this patch:

  # perf test dummy
  23: Test using a dummy software event to keep tracking       : Skip

perf tests: Make attr script verbose friendly

2013-03-15T16:05:59+00:00

Making the attr test script runner to pass proper verbose option. Also
making single '-v' be more reader friendly and display just the test
name.

Making the current output to be display for '-vv'.

perf tools, powerpc: Fix compile warnings in tests/attr.c

2013-01-30T13:37:14+00:00

We print several '__u64' quantities using '%llu'. On powerpc, we by
default include ' which results in __u64 being an
unsigned long. This causes compile warnings which are treated as errors
due to '-Werror'.

By defining __SANE_USERSPACE_TYPES__ we include 
and define __u64 as unsigned long long.

Changelog[v2]:
	[Michael Ellerman] Use __SANE_USERSPACE_TYPES__ and avoid PRIu64
	format specifier - which as Jiri Olsa pointed out, breaks on x86-64.

perf tests: Check python path on attr and binding test

2013-01-24T19:40:10+00:00

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
the attr test also.
