What kind of events are you trying to capture and then analyze?

Is it possible that what you want would be something like this:

=C2=A0xentrace -D -e 0x2f000 output.trace

(note the difference between your 0x20f000 and my 0x2f000)

This part looks ok.

Once you've got the event selection right, I'd suggest you to have a
look at xenalyze as well.
