KGTP is still not meet my requirement on Linux tracing.
ktap don't have gcc or gdb dependence, it's build from scratch, with a

You will find more differences if you watch ktap and kgtp deeply. :)

You are right, LTTng should be possible, and I already planed it, also
on some functionality of ftrace and systemtap.

Let's wait public ktap for a little time, you then can get a basic
overview on ktap.
