[PATCH 00/23] perf: integrate with kconfig and CONFIG driven features

[David Ahern]

Patches can also be retrieved from:
  https://github.com/dsahern/linux.git perf-config

I still need to add the conf build targets from the top level Makefile.

For this RFC series, you can run the commands manually to generate the
.config file for perf and the corresponding include/config/auto.conf and
include/generated/autoconf.h files.

To build conf (if it already exists in kernel tree jump to the conf
commands below):

BLDDIR=/tmp/perf-build
SRCDIR=/path/to/kernel.git

BLDDIR=/tmp/perf
SRCDIR=/opt/sw/perf/ahern.git

mkdir $BLDDIR
cd $BLDDIR
mkdir -p include/config include/generated
rsync -av $SRCDIR/scripts/ scripts/
ln -s $SRCDIR source
cd $SRCDIR
make O=$BLDDIR V=1 scripts/kconfig conf

Ignore the .config errors - those relate to the kernel build.
What matters here is that conf is built.

cd $BLDDIR
touch .config
PATH=$BLDDIR/scripts/kconfig:$PATH ARCH=x86 conf --silentoldconfig $SRCDIR/tools/perf/Pconfig

At this point you are asked what options to enable:

Enable newt-based TUI (NEWT) [N/y] (NEW) y
Enable GTK-based UI (GTK2) [N/y] (NEW) n
Enable support for Bionic (e.g., Android platform) (BIONIC) [N/y] (NEW)
Development support for libc is available - glibc or bionic (LIBC) [N/y] (NEW) y
  Enable support for libelf (LIBELF) [N/y] (NEW) y
    Enable support for libunwind (LIBUNWIND) [N/y] (NEW) y
    Enable support for dwarf (DWARF) [N/y] (NEW) y
    Enable support for demangle (DEMANGLE) [N/y] (NEW) y
Enable support for perl scripting engine (LIBPERL) [N/y] (NEW) y
Enable support for python scripting engine (LIBPYTHON) [N/y] (NEW) y
Enable support for libaudit (LIBAUDIT) [N/y/?] (NEW) y
Enable support for libnuma (LIBNUMA) [N/y/?] (NEW) y
Enable support for stack backtrace debugging (BACKTRACE) [N/y] (NEW) y

\# configuration written to .config
\#

Now build it:
cd $SRCDIR

make -C tools/perf O=$BLDDIR DESTDIR=/tmp/perf-install -j 4
