3 | Here the status of the work in progress for LTT experimental<br> |
| 4 | <br> |
| b720b182 |
5 | * Done<br> |
| b720b182 |
6 | remove ltt-headers.h<br> |
| 7 | remove ltt-log.h<br> |
| c9eaf4ed |
8 | Put trace->active later in _ltt_trace_start()<br> |
| 9 | ltt_trace_create() remove sleep in spinlock use GFP_ATOMIC kmalloc<br> |
| 1502fa62 |
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> |
| 24c78300 |
13 | Finish the control module, libltt and lttctl : netlink interface<br> |
| baffa645 |
14 | Finish integrating lttctl with lttd.<br> |
| ada84671 |
15 | fix lttctl signal waiting : use a flag.<br> |
| 4e4d11b3 |
16 | Add ltt_write_commit_counter call to genevent.<br> |
| 24c78300 |
17 | Add information in the buffer header : buffer size, etc etc...<br> |
| 18 | -> this information is so small that we can repeat it. Makes flight recorder |
| 19 | easier to decode.<br> |
| 4e4d11b3 |
20 | Add trace start structure to buffer start header.<br> |
| ada84671 |
21 | fix genevent : take no lock if num traces active is 0.<br> |
| 15e89ad6 |
22 | <br> |
| 23 | <br> |
| 4e4d11b3 |
24 | * TODO<br> |
| 25 | Add type information per facility : it will help having a standard way |
| 26 | to understand information coming from both kernel space and user space, and deal |
| 27 | easily with 64 bits kernel with 64 and 32 bits processes (and with size_t know |
| 28 | at compile time which can differ inside the same process from one library to |
| 29 | another).<br> |
| 30 | fix structures alignment, array and sequences too. -> trace dynamic.<br> |
| 31 | add per facility alignment (inside structures).<br> |
| 32 | add control of alignment.<br> |
| 33 | add user space tracing.<br> |
| 34 | <br> |
| 35 | <br> |
| b720b182 |
36 | <br> |
| 37 | * TODO (low priority)<br> |
| b720b182 |
38 | Integrate header generation (genevent) in kernel build system.<br> |
| c9eaf4ed |
39 | Multithreaded lttd.<br> |
| baffa645 |
40 | Find a different way to printk from instrumentation : forbidden from schedule |
| 41 | and wakeup (causes a deadlock).<br> |
| b720b182 |
42 | <br> |
| 15e89ad6 |
43 | * Need to be discussed<br> |
| b720b182 |
44 | Drop ltt-module-register and ltt-module-unregister, use exported variables.<br> |
| 45 | RelayFS ioctl interface vs control through LTT netlink interface.<br> |
| 46 | drop ltt_filter_control, use functions pointers instead.<br> |
| b720b182 |
47 | Merge facilities headers into one big header.<br> |
| 48 | Change the name of XML files from XML to something else.<br> |
| 49 | Remove ltt-base.c.<br> |
| 50 | <br> |
| 15e89ad6 |
51 | * Not planned for integration<br> |
| 4f782cda |
52 | Remove the callback struct from the trace struct.<br> |
| 15e89ad6 |
53 | <br> |
| 54 | <br> |
| b720b182 |
55 | <br> |
| 56 | * Next experimental release patch division :<br> |
| 57 | <br> |
| 58 | ltt-instrumentation.diff<br> |
| 59 | - ltt-configmenu.diff (put in ltt-core.diff)<br> |
| 60 | ltt-facilities-headers.diff<br> |
| 61 | ltt-facilities-loader.diff<br> |
| 62 | ltt-facilities.diff<br> |
| 63 | ltt-instrumentation.diff<br> |
| 64 | ltt-relayfs.diff<br> |
| 65 | ltt-time.diff<br> |
| 66 | ltt-core.diff<br> |
