   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 brackets [ ].<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 (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 (7) Create a hardware counter viewer (low cost rate counters : L1 cache miss, page faults, interrupts...).<br>
  25 (10) Add cancel button to LTTV filter GUI window.
  26 <br>

  28 <big>LTT Next Generation Roadmap<small><br>
  29 <br>
  30 * TODO<br>
  31 (1) Use 2.6.14 RelayFS control files.<br>
  32 (2) add efficient and secure user space tracing. (1 month)<br>
  33 (3) integrate LTTng State Dump : missing irq and process state.<br>
  34         # <A HREF="mailto:Jean-Hugues Deschenes <jean-hugues.deschenes@polymtl.ca>">Jean-Hugues Deschenes</A><br>
  35 (4) efficient dynamic event filtering while recording trace.<br>
  36         % Sensis Corp. <A HREF="mailto:Bish, Tim <Tim.Bish@Sensis.com>">Tim Bish</A><br>
  37 (5) Integrate LTTng and lttd with LKCD.<br>
  38 (7) add gcc -finstrument-functions instrumentation<br>
  39 (7) Integrate periodical dump of perfctr hardware counters.<br>
  40 (3) port LTTng to :<br>
  41 x86_64<BR>

  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>
  47 PPC64<BR>

  57 <br>
  58 <br>
  59 <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 do 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>
