At least userspace tracing seems to work.

I would recommended, again, that you first try tracing on a dummy application, a
really simple one. Then move to the usage of cyg_profile on that dummy app then
to your application.

The cyg profile events are the following:


and, when using


I would recommend that you first start grep-ing (lttng_ust_cyg) for this in the
trace to see if any is getting hit and recorded. If it is not the case, take a
step back try with a dummy app and if nothing works with the dummy app we can at
least try to help you from there and remove all other variable since you will be
able to share the dummy app with us.
