(3) Make LTTV aware of type formats (visual separators) defined in the XML
file.<br>
(3) Use a per architecture enumeration for traps.<br>
+(3) Change the byte pair "facility, event" id for a short combining the
+informatinon.<br>
+(4) Statistics per time window.<br>
+(4) Disable plugins when threshold reached (i.e. too much process in control
+flow view). Draw, and, when the threshold is reached, stop drawing. The global
+statistics view can inhibit showing the per process stats.<br>
+(4) Add a visual artifact : PID 0 could be named swapper instead of UNNAMED for
+cpus > 0.<br>
(4) Add event specific fields support to filter.<br>
(4) Add a periodic event interval view. (useful to verify event periodicity)<br>
(4) create a graphical per cpu activity view.<br>
+(4) Filter by target process.<br>
+(4) Compensate for time spent in probes in LTTV analysis.<br>
+(4) Add CPU, network, disk, memory usage histogram. [Per interval statistics]<br>
(5) Add Python scripting hooks.<br>
+(5) Add GUI interface to take an hybrid trace.<br>
(5) Flight recorder : start lttd automatically upon GUI trace control stop.<br>
(5) Automatically detect traces with too much processes and disable faulty operations.<br>
(5) Event sequence detector (inspired from regular expressions).<br>
view into a view of the evolution of a user definable event field.<br>

* TO FIX<br>
-(10) Event filter : event.time does not work.<br>
(10) Add cancel button to LTTV filter GUI window.<br>
(10) Sometimes, in the control flow view, a process with 0 creation time is
created in addition to the real process itself. Seems to be caused by end of

* TODO<br>
+(1) Integrate SystemTAP logging with LTTng.<br>
+(2) Rethink facility logging code (genevent output).<br>
+(2) Post an updated LTTng version to LKML (2.6.18-rcX).<br>
+(3) Change the byte pair "facility, event" id for a short combining the
+informatinon.<br>
(4) Add Xen support.<br>

(4) efficient dynamic event filtering while recording trace.<br>
% Sensis Corp. <A HREF="mailto:Bish, Tim <Tim.Bish@Sensis.com>">Tim Bish</A><br>
(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.<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>
+(4) Make page faults detect nested fault without nesting 4 times in the page
+fault handler.<br>
(5) Support CPUs with scalable frequency.<br>
(5) Integrate LTTng and lttd with LKCD.<br>
(7) Integrate periodical dump of perfctr hardware counters.<br>
(8) Integrate periodical dump of SystemTAP computed information.<br>
-(8) Integrate SystemTAP logging with LTTng.<br>
(9) Add support for setjmp/longjmp and jump tables instrumentation to
ltt-instrument-functions.<br>
(9) Make ltt-usertrace-fast support internal heartbeat timer.<br>
(3) port LTTng to :<br>
