| 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 | # <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>>">Mathieu Desnoyers</A><br> |
| 21 | (2) Fix bug with enums in lttv : make them use the value associated.<br> |
| 22 | # <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>>">Mathieu Desnoyers</A><br> |
| 23 | (4) create a event rate graphical view : Will be useful in conjonction with the |
| 24 | filter.<br> |
| 25 | # <A HREF="mailto:Parisa Heidari <parisa.heidari@polymtl.ca>">Parisa Heidari</A><br> |
| 26 | (6) migrate align to lttv parser.<br> |
| 27 | # <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>>">Mathieu Desnoyers</A><br> |
| 28 | (7) create an analysis of function time (like a precise gprof)<br> |
| 29 | -> with gcc -f inline-functions<br> |
| 30 | (10) Add cancel button to LTTV filter GUI window. |
| 31 | <br> |
| 32 | <br> |
| 33 | <big>LTT Next Generation Roadmap<small><br> |
| 34 | <br> |
| 35 | * TODO<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 | (5) Integrate LTTng and lttd with LKCD.<br> |
| 44 | (7) add gcc -finstrument-functions instrumentation<br> |
| 45 | (3) port LTTng to : (depends on 2.6.14 port)<br> |
| 46 | x86_64<BR> |

| 48 | L'Archeveque</A> for 2.6.9 RedHat Enterprise (patch available in contrib, still |
| 49 | has to be ported to 2.6.14, thanks!)<BR> |

| 61 | S/390<BR> |
| 62 | <br> |
| 63 | <br> |
| 64 | <br> |
| 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> |
| 75 | <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> |
| 82 | <br> |
| 83 | <br> |
| 84 | * lttng patch division (0.4.2+) :<br> |
