Description Tom Zanussi 2012-10-18 13:56:01 UTC

There are a set of recipes in oe-core that add LTTng version 2.0 support.  They seem to work fine after a couple simple patches are applied - the details of what currently works and the patches that need to be applied are described in the lttng section of the Yocto Tracing and Profiling Tools section under 'Projects' on the Yocto wiki:

https://wiki.yoctoproject.org/wiki/Tracing_and_Profiling#Tracing_and_Profiling_in_Yocto

In addition, the lttng-modules will be at some point going into 'LTSI upstream' and we'll need to coordinate that so it doesn't get broken at that point.

Comment 1 Tom Zanussi 2012-10-26 19:09:52 UTC

The patches mentioned in the Tracing and Profiling section have been pulled into master and should be pulled into the next danny point release:

poky/master: 683d54a6056a5f543802e2918e6eb96b7a5d3aa9

Tom, can this be closed?

Comment 3 Tom Zanussi 2012-12-13 16:32:08 UTC

This has been done recipe-wise, but still needs more testing e.g. lttng-ust, so we shoudn't close it yet.

Comment 4 Tom Zanussi 2013-01-08 22:17:03 UTC

lttng-ust has now been tested (details in the tracing and profiling wiki page) so this can now be closed.

Comment 5 Stefan Stanacar 2013-02-11 13:51:24 UTC

Verified in 1.4M3.
