[Buildroot] [pull request v3] Pull request for branch for-2012.02/lttng

[Thomas Petazzoni]

Hello,

Here is a set of patches that integrate the new generation LTTng
tracing infrastructure into Buildroot. There are several components in
this infrastructure:

 * lttng-modules are kernel modules that implement the kernel side of
   lttng. So far they are compatible with 2.6.38, 2.6.39, 3.0 and 3.1,
   and they don't require any kernel patches, they are simple external
   kernel modules.

 * lttng-tools are the userspace tools to start/stop and configure
   tracing sessions. They are typically installed on the target.

 * liburcu is an implementation of the RCU algorithm in userspace,
   used by lttng-tools.

 * lttng-babeltrace is the utility that allows to convert the binary
   traces generated by lttng-tools into a human-readable text
   format. A host variant of lttng-babeltrace is automatically built
   as a dependency of lttng-tools, because running babeltrace on the
   host machine is probably the most common use case. But building
   lttng-babeltrace for the target is also possible.

 * lttng-libust is an userspace library that allows applications to
   create their own trace events, which are combined with all other
   kernel events by lttng.

Some updates to the popt and util-linux packages are also required in
order to have an host variant of those packages, required to build the
host variant of lttng-babeltrace.

See http://lttng.org/lttng2.0 for more details.

Changes since v2 (submitted December 22nd 2011) :
 * Upgrade on top of current master
 * Add explanation about the configuration option for the host variant
   of util-linux, as suggested by Arnout Vandecappelle
 * Add DEPMOD=$(HOST_DIR)/usr/sbin/depmod to the LINUX_MAKE_FLAGS, as
   suggested by Thomas De Schampheleire, in order to tell the kernel
   to use our own depmod binary.
 * Ensure that host-busybox is not added to the dependencies of
   util-linux for the host.

Changes since v1 (submitted December 22nd 2011) :
 * Remove 'bleh.patch', leftover from previous tests/debugging.
 * Fix indentation in Config.in files
 * Make sure each file ends with a newline

Regards,

Thomas

[Buildroot] [PATCH 7/8] util-linux: add host variant for host-lttng-babeltrace

[Thomas Petazzoni]

lttng-babeltrace needs libuuid, which is provided by util-linux, and
since we want to build lttng-babeltrace for the host, we need to build
libuuid for the host. It's a shame that libuuid is part of such a big
package as util-linux.

HOST_..._DEPENDENCIES are now automatically derived from _DEPENDENCIES
by default, so this can be dropped.

Other than that it looks good, committed - Thanks.

It has been added by
http://git.buildroot.net/buildroot/commit/target/linux/Makefile.in?id=ea8b1fa6a60705eedc5bd4f405f45c8f531c2126,
which is a bit limited in details on why it was needed. I guess the
goal was to tell the Linux build process to use the lzma utility built
for the host by Buildroot, in case the Linux kernel is built (or the
initramfs) with LZMA compression. But that remains to be verified.

Ah, yes, sorry. The patch has been written prior to the introduction of
this mechanism, and I forgot to check this point. Thanks for taking
care of reviewing and fixing!

Yes, I know - But I don't see anything using it right away grepping the
kernel. I just wondered if anyone remembered what it was used for (and
if it still is)?

 I also looked in detail at the kernel and I also don't think it can be used 
by anything.  Maybe it used to be used at some point, but I don't feel like
grepping through the entire kernel history to find that :-)

 So I also think it can be removed.  Anyway, the TARGET_PATH will make sure
that our host-lzma is used.

 Regards,
 Arnout

 Do you know why this is necessary in the first place?  It should be
covered by the TARGET_MAKE_ENV with contains the TARGET_PATH, no?
Or is the problem that igh-ethercat and lttng-modules forget to
include TARGET_MAKE_ENV?

 Arnout
