I was able to successfully port lttng modules for android. I could see required KO files being cross compiled for Panda board by using modinfo command .

However, When I try to insert one of the module "lttng-tracer.ko" using insmod, It throws the following error.

{{{

lttng_tracer: Unknown symbol tracepoint_probe_unregister (err 0)

}}}

Please help me in resolving this

It might be a module dependency problem. You need to install all the modules that lttng-tracer is dependent on before installing itself.

If it is the problem, you can check the folder where you put the modules (for example on Ubuntu it's /lib/modules/3.5.0.30-generic). There you can find a file called modules.dep, which tells the sequence you should follow.
