LTT Next Generation Roadmap

* TODO
-(3) Find a way to make logging know when it causes a minor page fault -recursively (without ignoring silently all nested events).
+(1) CPU Hotplug support. (Only ltt-heartbeat needs to be fixed).
+(1) Add Xen support.
+ # Mathieu Desnoyers
+(1) Integrate SystemTAP logging with LTTng.
+(2) Test and post to LKML Linux Kernel Markers.
(3) Change the byte pair "facility, event" id for a short combining the informatinon.
-(4) Add Xen support.

(4) efficient dynamic event filtering while recording trace.
% Sensis Corp. Tim Bish
(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.
-(4) In flight recorder mode, have the low traffic channels saved as normal -tracefiles and high traffic channels being flight recorder.
-(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.
(4) integrate NPTL instrumentation (see PTT).
+(4) Probe calibration kernel module.
+(4) Make page faults detect nested fault without nesting 4 times in the page +fault handler.
(5) Support CPUs with scalable frequency.
+(5) Add boot time tracing support.
(5) Integrate LTTng and lttd with LKCD.
(7) Integrate periodical dump of perfctr hardware counters.
(8) Integrate periodical dump of SystemTAP computed information.
-(8) Integrate SystemTAP logging with LTTng.
+(9) Rethink facility logging code (genevent output). Maybe unneeded because of +markers/probes mechanism.
(9) Add support for setjmp/longjmp and jump tables instrumentation to ltt-instrument-functions.
(9) Make ltt-usertrace-fast support internal heartbeat timer.
