Subject[PATCH v3 0/4] tools: Add a toplevel Makefile
From: Borislav Petkov <>

Hi all,

yet another version of the toplevel Makefile integration of tools/.
This round gives you the ability to build the tools from the toplevel
Makefile (explanation below can be found also in patch 4/4's commit

"Now you can do

$ make tools/<toolname>

from the toplevel kernel directory and have the respective tool built.

If you want to build and install it, do

$ make tools/<toolname> tinstall

The install target is called "tinstall" so that there's no conflict with
the main kernel install target and should mean "tool install".

$ make tools/ <toolname>_clean

should clean the respective tool directories.

If you want to clean all in tools, simply do

$ make tools/ cleanall

Also, if you want to get what the possible targets are, simply calling

$ make tools/

should give you the short help."

Also included are all suggestions from the last time.



* v2:

here's a refreshed version from yesterday incorporating all comments and
suggestions along with a third patch that adds a 'help' target as the
default one causing the following below. Btw, Arnaldo, could you please
pick those up if there are no complaints since the first patch touches
perf and I don't have a clear idea who else to send it to anyway :).


$ make
Possible targets:

cpupower - a tool for all things x86 CPU power
firewire - the userspace part of nosy, an IEEE-1394 traffic sniffer
lguest - a minimal 32-bit x86 hypervisor
perf - Linux performance measurements tool
slub - slabs reporting tool
turbostat - Intel CPU idle stats and freq reporting tool
usb - USB testing tools
virtio - vhost test module
x86_energy_perf_policy - Intel energy policy tool

Cleaning targets:

all of the above with the "_clean" string appended cleans
the respective build directory.
clean: a summary clean target to clean _all_ folders

* v1:

this is a refresh and carve-out of an old patchset. It adds a toplevel
Makefile to tools/ so that one can build the tool of her/his liking by
simply doing

$ cd tools/
$ make <toolname>

By default, we build perf. There's also a scripts/Makefile.lib now which
should contain all make-related generic stuff which can be used by all
tools' build process after including this file.


Any comments/suggestions are welcome,
