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?

David 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) --- regards Manish Regmi http://manish-cs.blogspot.com http://ext2read.sf.net -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Is there a wiki page or document that gives suggestions on this? kvmtrace was depricated in favor of ftrace. kvm_stat still works. -- Gleb. -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
