using ftrace with kvm

I have a VM that is spinning (both vcpus at 100%). As I recall kvm_stat has been deprecated in favor or ftrace. Is there a wiki page or document that gives suggestions on this?

Documentation/trace/* is the place to see.

but for me function and function_graph give too much data even if i limit it to 1 function. so i use trace points. i simply enable the tracepoints i am interested in and read trace_pipe.

cat available_events
echo kvm:* > set_event
cat trace_pipe > ~/mydump.txt (or whatever you want to do)

kvmtrace was depricated in favor of ftrace. kvm_stat still works.
