Dear all, I am working on one project, which tries to profile the lock stats for one application, such as total waiting time for locks or how many locks happens during the execution.
I did some research, which shows "perf lock" may help to report such information, but I am getting the error showing as "tracepoint lock:lock_acquire is not enabled. Are CONFIG_LOCKDEP and CONFIG_LOCK_STAT enabled?". Does this mean, I need to recompile the kernel to have this option? Could anyone give me some link for this? I also got this link "http://article.gmane.org/gmane.linux.kernel.perf.user/770/match=perf+lock";, talking about profile the sleep times, but I cannot find how to use this. Any help would be great appreciated. Thanks!
