| | 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 | (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 (rates : 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 : (depends on 2.6.14 port)<br> |
| | 41 | x86_64<BR> |
| | 42 | #Autodesk <A HREF="mailto:Francois L'Archeveque <fla@discreet.com>">Francois |
| | 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> |

| | 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 does 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> |
