   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>
  10 <br>
  11 <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.<br>

  16 <big>LTTV Roadmap<small><br>
  17 <br>
  18 * TODO<br>
  19 (1) Port LTTV to genevent-new parser.<br>
  20 (2) Fix bug with enums in lttv : make them use the value associated.<br>
  21 (4) create a event rate graphical view : Will be useful in conjonction with the
  22   filter.<br>
  23         # <A HREF="mailto:Parisa Heidari <parisa.heidari@polymtl.ca>">Parisa Heidari</A><br>
  24 (6) migrate align to lttv parser.<br>
  25 (7) create an analysis of function time (like a precise gprof)<br>
  26   -> with gcc -f inline-functions<br>
  27 (10) Add cancel button to LTTV filter GUI window.

  30 <big>LTT Next Generation Roadmap<small><br>
  31 <br>
  32 * TODO<br>
  33 (1) add genevent full functionnality : alignment, array, sequences, nested
  34 structures.<br>
  35         # <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>>">Mathieu Desnoyers</A><br>
  36 (1) Use 2.6.14 RelayFS control files.<br>
  37 (1) port LTTng to 2.6.14 kernel. (depends on genevent rewrite)<br>
  38 (2) add efficient and secure user space tracing. (1 month)<br>
  39 (3) integrate LTTng State Dump : missing irq and process state.<br>
  40         # <A HREF="mailto:Jean-Hugues Deschenes <jean-hugues.deschenes@polymtl.ca>">Jean-Hugues Deschenes</A><br>
  41 (4) efficient dynamic event filtering while recording trace.<br>
  42         % Sensis Corp. <A HREF="mailto:Bish, Tim <Tim.Bish@Sensis.com>">Tim Bish</A><br>
  43 (7) add gcc -finstrument-functions instrumentation<br>
  44 (3) port LTTng to : (depends on 2.6.14 port)<br>

  63 * TODO (low priority)<br>
  64 enhance RPM packages for lttng kernel<br>
  65 Integrate header generation (genevent) in kernel build system.<br>
  66 Multithreaded lttd.<br>
  67 Find a different way to printk from instrumentation : forbidden from schedule
  68 and wakeup (causes a deadlock).<br>
  69 <br>
  70 * Need to be discussed<br>
  71 Drop ltt-module-register and ltt-module-unregister, use exported variables.<br>
  72 drop ltt_filter_control, use functions pointers instead.<br>
  73 Merge facilities headers into one big header.<br>
  74 Change the name of XML files from XML to something else.<br>
  75 Remove ltt-base.c.<br>
