22 | (7) create an analysis of function time (like a precise gprof)<br> |
| c8a111eb |
23 | -> with gcc -f inline-functions<br> |
| 575b7e97 |
24 | (7) Create a hardware counter viewer (rates : L1 cache miss, page faults, interrupts...).<br> |

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

63 | Multithreaded lttd.<br> |
| baffa645 |
64 | Find a different way to printk from instrumentation : forbidden from schedule |
| 63eeefc3 |
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> |

71 | * Need to be discussed<br> |
| b720b182 |
72 | Drop ltt-module-register and ltt-module-unregister, use exported variables.<br> |
| b720b182 |
73 | drop ltt_filter_control, use functions pointers instead.<br> |
| b720b182 |
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> |
