From mboxrd@z Thu Jan 1 00:00:00 1970 From: compudj@krystal.dyndns.org (Mathieu Desnoyers) Date: Tue, 27 Jan 2009 16:02:03 -0500 Subject: [ltt-dev] LTTng 0.87 improved page fault tracing Message-ID: <20090127210203.GA13478@Krystal> Hi, I just combined the 4 page fault handler events that were in the tracing hot path of LTTng into 2 : kernel page_fault_entry kernel page_fault_exit They take as parameter the combination of what was available in the trap_entry/exit events and handle_mm_fault entry/exit events. This should lessen the performance impact of the tracer when it's active. I did the related modifications in LTTV 0.12.8.
