Hi Mathieu,
I had some query regarding implementation of *LTTng* on *RT* kernel. The
kernel version used is *Linux-2.6.29*, RT patch version is *patch-2.6.29-rt1
*and* *LTTng version is *2.6.29-lttng-0.116. *I see few of the LTTng commits
are already present in RT patch, I see few clashes in
include/linux/tracepoint.h file... Do I need to drop certain commits from
LTTng-2.6.29-0.116 to cleanly apply and integrate LTTng on top of RT kernel
?
Note : ARCHITECTURE :* PowerPC**-440*
Regards
Srikanth Krishnakar

It is going to be a case-by-case thing. Some tracepoints commits are
really needed. The immediate values-related commits can be ignored,
since they represent an optimisation.

Which commits from 2.6.29-LTTng-0.116 from can really be dropped and how we
are handling *preempt_enable* of RT before trace ?
Thanks ..
