[RFC 00/27] perf tools: Build changes and kbuild support

[RFC 00/27] perf tools: Build changes and kbuild support

[Jiri Olsa]

hi,
sending RFC for build changes and kbuild support.

The build changes mostly consists of separating the config
stuff into config/Makefile which is then used for kbuild.

I kept the original/current Makefile in place and put
the kbuild support into Makefile.kbuild. The final touch
would be to move Makefile.kbuild into Makefile. I kept
the original one to have easy way of testing the old
system.

To run the kbuild make:
  $ make -f Makefile.kbuild

In pristine tree above command behaves as the current
Makefile - does the system checks and builds perf.

After that '.config' and '.config-detected' files
are created and managed as explained in last patch
of this set.

It's published in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/kbuild7

I tested this so far on x86_64.

I'm CC-ing Michal Marek and linux-kbuild list on kbuild patches.

thanks for comments,
jirka

[PATCH 27/27] perf tools: Add kbuild support into Makefile.kbuild

[Jiri Olsa]

Adding kbuild support into Makefile.kbuild. The 'legacy'
Makefile still stays untouched as it was.

It's possible to use kbuild by running 'make -f Makefile.kbuild'
with any option supported by 'legacy' Makefile.

We now have 2 config files:
  '.config' - user configured setup
  '.config-detected' - system detected setup

The '.config-detected' affects '.config' and if there's
configured feature in '.config' which was not detected
it is automatically disabled.

The '.config-detected' is re/created if:
  - there's no '.config-detected'
  - '.config' was changed

In a cleaned tree the perf is built with 'allyesconfig'
having disabled all non-detected features, just as it is
done now.

You can change '.config' via:
  make -f Makefile.kbuild menuconfig

There's difference for O=DIR build. The DIR is populated
based on kernel source tree, so the final binary is created
under DIR/tools/perf.

When readign the Kbuild file I get confused.
the obj-y syntax is used for kernel built-in stuff,
and obj-m for modules.
I had expected either a perf specific syntax or something like the
syntax used for host programs.

Have you seen this patch set:
https://lkml.org/lkml/2012/8/20/59

It hooks into the conf commands to generate a .config file. 
Coincidentally I updated and expanded the patch series this morning to 
include dependencies and such. Latest Pconfig attached to give you an 
idea. I need to collapse a few patches and send them out tonight.

While building kernel you need to have separate flags
for internal objects and for host programs.

First, I thought I need to separate it as you say, but
perf build is separated from kernel built process, so
AFAICS we can use obj-y with no harm in perf.

It's quite possible I missed something and kbuild folks
prove me wrong ;-)

The Makefile.kbuild defines flags to be used for obj-y.

yep, I remember checking it.. but I decided to start over
because I wanted to use kbuild build support as well

Now when I'm checking that I see you made also some source
changes to make the build separation possible. I haven't done
much on this part and some of the libraries/features/builtins
could not be disabled at the moment, because the code
is not properly separated.

I suggest to just append .cmd to the auto.conf name, instead of
introducing a new environment variable.

(I haven't looked at the rest of the patches yet).
