16 | <big>LTTV Roadmap<small><br> |
| 17 | <br> |
| 18 | * TODO<br> |
| ef19b009 |
19 | (3) Make LTTV aware of type formats (visual separators) defined in the XML |
| 20 | file.<br> |
| 15b0e8a4 |
21 | (3) Use a per architecture enumeration for traps.<br> |
| 16fe6efa |
22 | (4) Add event specific fields support to filter.<br> |
| 2d569f51 |
23 | (4) create a graphical per cpu activity view.<br> |
| b35779fc |
24 | (5) Add Python scripting hooks.<br> |
| b0a1cd56 |
25 | (5) Flight recorder : start lttd automatically upon GUI trace control stop.<br> |
| caf22319 |
26 | (5) Automatically detect traces with too much processes and disable faulty operations.<br> |
| b0a1cd56 |
27 | (5) Event sequence detector (inspired from regular expressions).<br> |
| c5cab5d9 |
28 | (7) Create a hardware counter viewer (low cost rate counters : L1 cache miss, |
| 29 | page faults, interrupts...). This will be a generalisation of the event rate |
| 30 | view into a view of the evolution of a user definable event field.<br> |
| 16383052 |
31 | (10) Add cancel button to LTTV filter GUI window. |

| 73 | * TODO (low priority)<br> |
| cbe85414 |
74 | enhance RPM packages for lttng kernel<br> |
| b720b182 |
75 | Integrate header generation (genevent) in kernel build system.<br> |
| baffa645 |
76 | Find a different way to printk from instrumentation : forbidden from schedule |
| 63eeefc3 |
77 | and wakeup (causes a deadlock). -> Modify printk so it uses LTTng tracer!<br> |
| 78 | Export channels via network sockets instead of writing them to disk.<br> |
| 79 | Export buffers with time constraint for "live" visualisation. Use |
| 6b18b620 |
80 | ltt_force_switch periodically from a timer to insure slow channels do not |
| 63eeefc3 |
81 | interfere with viewing.<br> |
| 44397e24 |
82 | Have an optional round-robin mode to write information into multiple channels |
| 83 | from the same source.<br> |
| b720b182 |

85 | * Need to be discussed<br> |
| af3cfedc |
86 | Use 2.6.14 RelayFS control files.<br> |
| b720b182 |
87 | Drop ltt-module-register and ltt-module-unregister, use exported variables.<br> |
| b720b182 |
88 | drop ltt_filter_control, use functions pointers instead.<br> |
| b720b182 |
89 | Merge facilities headers into one big header.<br> |
| 90 | Change the name of XML files from XML to something else.<br> |
| 91 | Remove ltt-base.c.<br> |
