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>
13 The # symbol marks who is currently working on the item.
<br>
14 The % symbol marks who is interested in the realisation of the item.

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>
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>
79 * lttng patch division (
0.4.2+) :
<br>
81 ltt-instrumentation.diff
<br>
82 ltt-facilities-headers.diff
<br>
83 ltt-facilities-loader.diff
<br>
84 ltt-facilities.diff
