<big>LTTV Roadmap<small><br>
<br>
* TODO<br>
-(3) Make LTTV aware of type formats defined in the XML file.<br>
+(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) Integrate Kernel State Dump information.<br>
-(4) create a event rate graphical view : Will be useful in conjunction with the
- filter.<br>
- # <A HREF="mailto:Parisa Heidari <parisa.heidari@polymtl.ca>">Parisa Heidari</A><br>
+(4) Add event specific fields support to filter.<br>
(4) create a graphical per cpu activity view.<br>
(5) Add Python scripting hooks.<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>
-(7) create an analysis of function time (like a precise gprof).<br>
- -> with gcc -f inline-functions<br>
-(7) Create a hardware counter viewer (low cost rate counters : L1 cache miss, page faults, interrupts...).<br>
+(7) Create a hardware counter viewer (low cost rate counters : L1 cache miss,
+page faults, interrupts...). This will be a generalisation of the event rate
+view into a view of the evolution of a user definable event field.<br>
(10) Add cancel button to LTTV filter GUI window.

<big>LTT Next Generation Roadmap<small><br>
<br>
* TODO<br>
-(2) add efficient and secure user space tracing. (1 month)<br>
+(2) Make ltt-usertrace-fast support internal heartbeat timer.<br>
# <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>">Mathieu Desnoyers</A><br>
-(3) integrate LTTng State Dump : missing irq and process state.<br>
+(3) LTTng State Dump : fix process states (currently forced to unknown).<br>
# <A HREF="mailto:Jean-Hugues Deschenes <jean-hugues.deschenes@polymtl.ca>">Jean-Hugues Deschenes</A><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) 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>
+(5) Support CPUs with scalable frequency.<br>
(5) Integrate LTTng and lttd with LKCD.<br>
(6) Add Xen support.<br>
-(7) add gcc -finstrument-functions instrumentation<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>
(3) port LTTng to :<br>

* TODO (low priority)<br>
enhance RPM packages for lttng kernel<br>
Integrate header generation (genevent) in kernel build system.<br>
-Multithreaded lttd.<br>
Find a different way to printk from instrumentation : forbidden from schedule
and wakeup (causes a deadlock). -> Modify printk so it uses LTTng tracer!<br>
Export channels via network sockets instead of writing them to disk.<br>
Export buffers with time constraint for "live" visualisation. Use
ltt_force_switch periodically from a timer to insure slow channels do not
interfere with viewing.<br>
+Have an optional round-robin mode to write information into multiple channels
+from the same source.<br>
<br>
* Need to be discussed<br>
Use 2.6.14 RelayFS control files.<br>
Remove ltt-base.c.<br>
