6 Here are the roadmaps for the LTTV and LTTng development. I use a priority indice
7 for the TODO items :<br>
8 (1) : very high priority<br>
9 (10): lowest priority<br>

18 * TODO<br>
19 (4) create a event rate graphical view : Will be useful in conjonction with the
20 filter.<br>
21 # <A HREF="mailto:Parisa Heidari <parisa.heidari@polymtl.ca>">Parisa Heidari</A><br>
22 (7) create an analysis of function time (like a precise gprof)<br>
23 -> with gcc -f inline-functions<br>
24 (10) Add cancel button to LTTV filter GUI window.

29 * TODO<br>
30 (1) port LTTng to 2.6.14 kernel.<br>
31 # <A HREF="mailto:Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>">Mathieu Desnoyers</A><br>
32 (1) Use 2.6.14 RelayFS control files.<br>
33 (2) add efficient and secure user space tracing. (1 month)<br>
34 (3) integrate LTTng State Dump : missing irq and process state.<br>
35 # <A HREF="mailto:Jean-Hugues Deschenes <jean-hugues.deschenes@polymtl.ca>">Jean-Hugues Deschenes</A><br>
36 (4) efficient dynamic event filtering while recording trace.<br>
37 % Sensis Corp. <A HREF="mailto:Bish, Tim <Tim.Bish@Sensis.com>">Tim Bish</A><br>
38 (5) Integrate LTTng and lttd with LKCD.<br>
39 (7) add gcc -finstrument-functions instrumentation<br>
40 (3) port LTTng to : (depends on 2.6.14 port)<br>
41 x86_64<BR>
42 #Autodesk <A HREF="mailto:Francois L'Archeveque <fla@discreet.com>">Francois
43 L'Archeveque</A> for 2.6.9 RedHat Enterprise (patch available in contrib, still
44 has to be ported to 2.6.14, thanks!)<BR>
45 %Wind River for 2.6.14<BR>
46 PPC<BR>

60 * TODO (low priority)<br>
61 enhance RPM packages for lttng kernel<br>
62 Integrate header generation (genevent) in kernel build system.<br>
63 Multithreaded lttd.<br>
64 Find a different way to printk from instrumentation : forbidden from schedule
65 and wakeup (causes a deadlock). -> Modify printk so it uses LTTng tracer!<br>
66 Export channels via network sockets instead of writing them to disk.<br>
67 Export buffers with time constraint for "live" visualisation. Use
68 ltt_force_switch periodically from a timer to insure slow channels does not
69 interfere with viewing.<br>
70 <br>
71 * Need to be discussed<br>
72 Drop ltt-module-register and ltt-module-unregister, use exported variables.<br>
73 drop ltt_filter_control, use functions pointers instead.<br>
74 Merge facilities headers into one big header.<br>
75 Change the name of XML files from XML to something else.<br>
76 Remove ltt-base.c.<br>
77 <br>
78 <br>
79 * lttng patch division (0.4.2+) :<br>
