perf tools: Add reference counting for thread_map object

2015-06-25T18:15:50+00:00

Adding reference counting for thread_map object, so it could be easily
shared among other objects.

Using thread_map__put instead thread_map__delete and making
thread_map__delete static.

tools lib api: Adopt fdarray class from perf's evlist

2014-09-25T19:46:55+00:00

The extensible file description array that grew in the perf_evlist class
can be useful for other tools, as it is not something that only evlists
need, so move it to tools/lib/api/fd to ease sharing it.

v2: Don't use {} like in:

 libapi_dirs:
	$(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/

in Makefiles, as it will not work in some systems, as in ubuntu13.10.

v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa)

v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to
    be checked if it is really needed there, but has no place in the
    fdarray class (Fix from Jiri Olsa)

v5: Remove evlist details from fdarray grow/filter tests. Improve it a
    bit doing more tests about expected internal state.

perf evlist: Introduce poll method for common code idiom

2014-09-25T19:46:55+00:00

Since we have access two evlist members in all these poll calls, provide
a helper.

This will also help to make the patch introducing the pollfd class more
clear, as the evlist specific uses will be hiden away
perf_evlist__poll().

perf tools: Factor eprintf to allow different debug variables

2014-07-17T15:58:59+00:00

This way we can easily reuse current debug functions for another debug
variables other than verbose.

perf evlist: Introduce evlist__for_each() & friends

2014-01-13T13:06:25+00:00

For the common evsel list traversal, so that it becomes more compact.

Use the opportunity to start ditching the 'perf_' from 'perf_evlist__',
as discussed, as the whole conversion touches a lot of places, lets do
it piecemeal when we have the chance due to other work, like in this
case.

perf tools: Fixup mmap event consumption

2013-10-28T19:06:00+00:00

The tail position of the event buffer should only be modified after
actually use that event.

If not the event buffer could be invalid before use, and segment fault
occurs when invoking perf top -G.

perf tools: Adding throttle event data struct support

2013-10-09T14:39:18+00:00

Moving 'struct throttle_event' out of python code and making it global
as any other event.

There's no usage of throttling events in any perf commands so far
(besides python support), but we'll need this event data backup for
upcoming test.
