From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Petazzoni Date: Tue, 31 Jan 2012 20:39:58 +0100 Subject: [Buildroot] [pull request v3] Pull request for branch for-2012.02/lttng Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net 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 The following changes since commit cf96a9bec0c2ad40b820c6f465c2ac17d3bc4e03: libevas: really fix x86 cpu optimization options handling (2012-01-30 23:22:51 +0100) are available in the git repository at: http://free-electrons.com/~thomas/buildroot.git for-2012.02/lttng Thomas Petazzoni (8): linux: use the depmod built in HOST_DIR liburcu: new package lttng-modules: new package lttng-libust: new package lttng-tools: new package popt: add host variant for host-lttng-babeltrace util-linux: add host variant for host-lttng-babeltrace lttng-babeltrace: new package linux/linux.mk | 3 +- package/Config.in | 5 ++++ package/liburcu/Config.in | 9 +++++++ package/liburcu/liburcu.mk | 8 ++++++ package/lttng-babeltrace/Config.in | 22 ++++++++++++++++ package/lttng-babeltrace/lttng-babeltrace.mk | 17 +++++++++++++ package/lttng-libust/Config.in | 10 +++++++ .../lttng-libust-fix-overflow-32-bits.patch | 26 ++++++++++++++++++++ package/lttng-libust/lttng-libust.mk | 8 ++++++ package/lttng-modules/Config.in | 18 +++++++++++++ package/lttng-modules/lttng-modules.mk | 16 ++++++++++++ package/lttng-tools/Config.in | 20 +++++++++++++++ package/lttng-tools/lttng-tools.mk | 12 +++++++++ package/popt/popt.mk | 1 + package/util-linux/util-linux.mk | 14 ++++++++++ 15 files changed, 188 insertions(+), 1 deletions(-) create mode 100644 package/liburcu/Config.in create mode 100644 package/liburcu/liburcu.mk create mode 100644 package/lttng-babeltrace/Config.in create mode 100644 package/lttng-babeltrace/lttng-babeltrace.mk create mode 100644 package/lttng-libust/Config.in create mode 100644 package/lttng-libust/lttng-libust-fix-overflow-32-bits.patch create mode 100644 package/lttng-libust/lttng-libust.mk create mode 100644 package/lttng-modules/Config.in create mode 100644 package/lttng-modules/lttng-modules.mk create mode 100644 package/lttng-tools/Config.in create mode 100644 package/lttng-tools/lttng-tools.mk Thanks, -- Thomas Petazzoni
