[PATCH 1/3] perf ui browser: Clean lines inside of the input window

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

As Arnaldo pointed out, it should be cleared to prevent the window from
displaying overlapped strings on the region.

[PATCH 3/3] perf report: Add a simple GTK2-based 'perf report' browser

[Arnaldo Carvalho de Melo]

From: Pekka Enberg <penberg@kernel.org>

This patch adds a simple GTK2-based browser to 'perf report' that's
based on the TTY-based browser in builtin-report.c.

To launch "perf report" using the new GTK interface just type:

  $ perf report --gtk

The interface is somewhat limited in features at the moment:

  - No callgraph support

  - No KVM guest profiling support

  - No color coding for percentages

  - No sorting from the UI

  - ..and many, many more!

That said, I think this patch a reasonable start to build future features on.

Pulled, thanks Arnaldo!

I noticed that there's no help text for GTK support - how will a 
user find that 'perf report --gtk' will do something nice?

Another detail is that if GTK support is not compiled in:

Makefile:515: GTK2 not found, disables GTK2 support. Please install gtk2-devel or libgtk2.0-dev

then the --gtk output is not very informative:

  earth5:~/tip/tools/perf> perf report --gtk
  earth5:~/tip/tools/perf> 

:-)

A third detail, I do have gtk2-devel installed:

 Package gtk2-devel-2.24.10-1.fc17.x86_64 already installed and latest version

yet I got the above message.

It is not easy to figure out *why* a feature test failed, 
unfortunately. It would be nice if V=1 or something like that 
would output the failure.

I applied the hack below and ran the gtk testcase, which gave:

earth5:~/tip/tools/perf> . ./test.4273.sh
In file included from /usr/lib64/glib-2.0/include/glibconfig.h:9:0,
                 from /usr/include/glib-2.0/glib/gtypes.h:34,
                 from /usr/include/glib-2.0/glib/galloca.h:34,

                 from test.4273.c:2:
/usr/include/glib-2.0/glib/gmacros.h:346:7: error: "_MSC_VER" is not defined [-Werror=undef]
cc1: all warnings being treated as errors

Which allowed me to fix the feature test and the gtk.h include 
file wrapper via the second patch below.

And then I was greeted by the GTK report window on 'perf report 
--gtk' ;-)

Thanks,

	Ingo

So, instead of this hack we'd like to output the build failure 
that gcc gives, when 'make V=1' is specified or so.

Thanks,

Ignore this one - I forgot to do 'make install-doc'.

Yeah, as you said, the ball is rolling! ;-)

Yeah, I also was frustrated by V=1 not affecting the feature tests, and
did what you did, just didn't got around to fix it properly.
