-(4) Create the heartbeat timer LTTng module. Make sure that heartbeat events
-never hit the facility channel. Use the complete 64 bits TSC for the facility
-channel in every case. That's because this channel must never be overwritten
-even in "flight recorder" mode.<br>
+(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.<br>
+(4) In flight recorder mode, have the low traffic channels saved as normal
+tracefiles and high traffic channels being flight recorder.<br>
+(4) Try to use my own non LOCK prefixed version of atomic operations : we are
+using per-CPU variables, so it should make it possible.<br>
+(4) integrate NPTL instrumentation (see
+<A HREF="http://nptltracetool.sourceforge.net/">PTT</A>).<br>
+(4) Probe calibration kernel module.<br>
+(5) Discuss with RelayFS upstream to integrate LTTng modifications.<br>
+(5) Move to DebugFS for channel files.<br>
+(5) Support CPUs with scalable frequency.<br>
