[PATCH 0/1] perfer older version of lttng-ust in poky distro

[Lianhao Lu]

Set the PREFERRED_VERSION of lttng-ust to use lttng-ust instead of 
lttng2-ust in poky distro. This fixed yocto bug #2062. 

The lttng2 is very different in terms of architecture and usage model, compared 
to lttng. The eclipse upstream lttng plugin won't be able to support lttng2 until 
the eclipse Juno release(Jun 27th, 2012).

The following changes since commit 8e9f6fc77ac4763f4ed1f6e7b720420c220ba6e2:

Hi Saul,

How about this patch's merging status?

Missed it becase it went to the wrong list!  should go to the 
poky@yoctoproject.org list in the future.

This patch seems to break the lttng-2.0/lttng-tools build.  Please 
verify that we can build lttng-2.0 bits or somehow handle both.

I am not sure the kernel will support the older lttng, in which case 
using lttng-ust from the older release will not work, so we can not use 
the eclipse with it anyways.

It won't. Since lttng 1.x wasn't ported past 2.6.38 (and released), since
lttng was moving to 2.x and the new CTF, there wasn't any sense in
porting it ourselves.

That being said, it IS possible for both 1.x and 2.x to co-exist, but
we don't have the weeks (or the value) in making the port.

Cheers,

Bruce

Just like Bruce said, I double checked that the older lttng-ust 1.x can work upon new kernel 3.2.11. So Saul, please ignore this patch. I'll send another patch to oe-core to change the name of new 2.x lttng-ust to lttng2-ust, so that it's possible to have them co-exist.
