cover lttng-2.0 new recipe

Hi All,

This patchset adds support for lttng-2.0, including the folloing four bb files:
babeltrace_0.8.bb
lttng-modules_v2.0.pre11.bb
lttng-tools_2.0-pre16.bb
lttng-ust_1.9.4.bb
And two patches for smoothly compiling:
lttng-modules-replace-KERNELDIR-with-KERNEL_SRC.patch lttng-tools-fix-compiling-error-for-powerpc-arm-and-mips.patch

There is a clear description of the LTTng 2.0 architecture in the followiing site:
http://lttng.org/sites/lttng.org/files/LTTng2_0Architecture_pa3.pdf

Currently lttng-2.0 is still in pre-release phrase, so I add this into the patch header for reminder. And another goal of this RR is intended to bring forward the following issues:

lttng-2.0 has been added into recipies-kernel, which coexisted with lttng(the previous version), because there are some mainly changes from lttng-control to lttng-tools, which both monitors tracepoints and dynamic probes from kernel and userspace. But I'm not sure if we should remove the previous version lttng. My suggestion is to preserve for 2.6.37 kernel :-)

lttng-2.0 supports lttng-modules extra builds, which don't need any patches on Linux kernel vs the previous version of lttng. As described in README of lttng-modules-2.0, so far, it has been tested in current 3.0 kernel on x86 32/64-bit, and powerpc 32-bit, , build tested on ARM. So the related tests on qemux86 and qemuppc has been validated and a build test on qemuarm passed too with this patcheset.

Babeltrace provides as a trace converter, which used to convert LTTng 2.0 traces into human-readable log(see below example for qemuppc)

lttng-ust_1.9.4 is Linux Trace Toolkit 2.0 Userspace Tracer.

I'm still keep an eye on the development of lttng for updates.

Regard,
Zumeng

I don't think this is what you meant. You are restricting the type of build system, not the type of target you can build for.

Sorry, I copied from liburcu, and I heard its Poky's convention.

Again, I think you want to filter based on target arch.

+SUMMARY = "Babeltrace - Trace Format Babel Tower"
+DESCRIPTION = "Babeltrace provides trace read and write libraries in host side,\
+	       as well as a trace converter, which used to convert LTTng 2.0 \
+	       traces into human-readable log."
In the previous patches you aligned the additional lines with column 0, here you indent with tabs and spaces. A quick survey of the existing sources suggest the DESCRIPTION field typically does not indent the subsequent lines.

OK. fixed.
