21 | (2) Fix bug with enums in lttv : make them use the value associated.<br> |
| 90d65afc |
22 | (4) create a event rate graphical view : Will be useful in conjonction with the |

25 | (6) migrate align to lttv parser.<br> |
| 26 | (7) create an analysis of function time (like a precise gprof)<br> |
| c8a111eb |
27 | -> with gcc -f inline-functions<br> |
| 16383052 |
28 | (10) Add cancel button to LTTV filter GUI window. |

63 | enhance RPM packages for lttng kernel<br> |

65 | Multithreaded lttd.<br> |
| baffa645 |
66 | Find a different way to printk from instrumentation : forbidden from schedule |
| 63eeefc3 |
67 | and wakeup (causes a deadlock). -> Modify printk so it uses LTTng tracer!<br> |
| 68 | Export channels via network sockets instead of writing them to disk.<br> |
| 69 | Export buffers with time constraint for "live" visualisation. Use |
| 70 | ltt_force_switch periodically from a timer to insure slow channels does not |
| 71 | interfere with viewing.<br> |

72 | <br> |
| 15e89ad6 |
73 | * Need to be discussed<br> |
| b720b182 |
74 | Drop ltt-module-register and ltt-module-unregister, use exported variables.<br> |
| b720b182 |
75 | drop ltt_filter_control, use functions pointers instead.<br> |
| b720b182 |
76 | Merge facilities headers into one big header.<br> |
| 77 | Change the name of XML files from XML to something else.<br> |
