Hi everyone,
I just ported LTTng to 2.6.28. Enjoy !
You may also want to upgrade to lttv 0.12.5 which puts back the syscall
and softirq names in the event list.
For newcomers, instructions to install LTTng can be found at :
http://ltt.polymtl.ca/svn/trunk/lttv/QUICKSTART
(I just updated the QUICKSTART guide. Please feel free to try it and
report inconsistencies.)

Hi,
LTTng 0.74 fixes the probe Makefile to build the net-trace probe module.
It also adds jbd2 and ext4 tracepoints, and jbd2 probe module.
A new version including ext4 probe module should be available shortly.
Installation QUICKSTART :

Hi Kosaki,
Thanks for the report. This should be fixed in LTTng 0.78 now.

Unfortunately, lockdep part also can't build.

Subject: [PATCH] fix lockdep tracing build error
commit 6afe40b4dace385d7ba2faf24b352f066f3b71bf rename argument a0 to ip.
it cause following build error to lttng tree.
CC kernel/lockdep.o
kernel/lockdep.c: In function 'trace_hardirqs_on_caller':
kernel/lockdep.c:2186: error: 'a0' undeclared (first use in this function)
kernel/lockdep.c:2186: error: (Each undeclared identifier is reported only once
kernel/lockdep.c:2186: error: for each function it appears in.)
kernel/lockdep.c: In function 'trace_hardirqs_off_caller':
kernel/lockdep.c:2241: error: 'a0' undeclared (first use in this function)
make[1]: *** [kernel/lockdep.o] Error 1
therefore we also need change trace argument.

Out of curiosity, do you maintain a branch of LTTNG versus any of the
-rc kernels, or do you only track the stable kernels? I tried pulling
LTTNG 0.78 against the most recent Linus mainline and got a whole pile
of conflicts.
I then tried building LTTng 0.78 and got build failures:
CC arch/x86/kernel/init_task.o

Looks like CONFIG_MARKERS_USERSPAC is busted....

I may be missing something, but I'm pretty sure the
lttng-instrumentation-lockdep.patch in 0.78 also fixes this. (it's been
updated)

Hi Ted,
I'm currently integrating Lai's work to the 2.6.28 lttng branch (ascii
output !) :) and the next step will be to move to 2.6.29-rc1. I'll keep
you posted. Note that you can just leave the
#New revamped userspace markers
markers-userspace.patch
markers-userspace-x86.patch
markers-userspace-x86_64.patch
sparc64-support-userspace-tracing.patch
Out of the patchset and it should not hurt the kernel tracing part at
all. Note that these 4 patches are planned to be heavily reworked before
lkml submission.

Actually, the x86_32 2.6.28 build was broken because of a bad patch
hunk which caused this problem. I fixed it in lttng 0.81. The port to
2.6.29-rc1 should some in a few days.
Thanks for the report,
