| 3 | Here the status of the work in progress for LTT experimental<br> |
| 4 | <br> |
| 5 | * Done<br> |
| 6 | remove ltt-headers.h<br> |
| 7 | remove ltt-log.h<br> |
| 8 | Put trace->active later in _ltt_trace_start()<br> |
| 9 | ltt_trace_create() remove sleep in spinlock use GFP_ATOMIC kmalloc<br> |
| 10 | Fix the locking of module hooks.<br> |
| 11 | Fix the traps -> disable nested logging for now.<br> |
| 12 | Use per cpu spinlock on trace list.<br> |
| 13 | Finish the control module, libltt and lttctl : netlink interface<br> |
| 14 | Finish integrating lttctl with lttd.<br> |
| 15 | fix lttctl signal waiting : use a flag.<br> |
| 16 | <br> |
| 17 | <br> |
| 18 | * TODO<br> |
| 19 | Add information in the buffer header : buffer size, etc etc...<br> |
| 20 | -> this information is so small that we can repeat it. Makes flight recorder |
| 21 | easier to decode.<br> |
| 22 | Add trace start structure to facility channel.<br> |
| 23 | fix genevent : take no lock if num traces active is 0.<br> |
| 24 | <br> |
| 25 | <br> |
| 26 | <br> |
| 27 | * TODO (low priority)<br> |
| 28 | Integrate header generation (genevent) in kernel build system.<br> |
| 29 | Multithreaded lttd.<br> |
| 30 | Find a different way to printk from instrumentation : forbidden from schedule |
| 31 | and wakeup (causes a deadlock).<br> |
| 32 | <br> |
| 33 | * Need to be discussed<br> |
| 34 | Drop ltt-module-register and ltt-module-unregister, use exported variables.<br> |
| 35 | RelayFS ioctl interface vs control through LTT netlink interface.<br> |
| 36 | drop ltt_filter_control, use functions pointers instead.<br> |
| 37 | Merge facilities headers into one big header.<br> |
| 38 | Change the name of XML files from XML to something else.<br> |
| 39 | Remove ltt-base.c.<br> |
| 40 | <br> |
| 41 | * Not planned for integration<br> |
| 42 | Remove the callback struct from the trace struct.<br> |
| 43 | <br> |
| 44 | <br> |
| 45 | <br> |
| 46 | * Next experimental release patch division :<br> |
| 47 | <br> |
| 48 | ltt-instrumentation.diff<br> |
| 49 | - ltt-configmenu.diff (put in ltt-core.diff)<br> |
| 50 | ltt-facilities-headers.diff<br> |
| 51 | ltt-facilities-loader.diff<br> |
| 52 | ltt-facilities.diff<br> |
| 53 | ltt-instrumentation.diff<br> |
| 54 | ltt-relayfs.diff<br> |
| 55 | ltt-time.diff<br> |
| 56 | ltt-core.diff<br> |
