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>
12 Dependencies are written between parenthesis ( ).

<br>
37 (
1) port LTTng to
2.6.14 kernel. (depends on genevent rewrite)
<br>
38 (

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

89 ltt-facilities.diff
