3 | Progress in LTTV :<br> |
| 4 | * Done<br> |
| 3490c00c |
5 | Buffer aligned on page boundary -> use valloc.<br> |
| d6533ec7 |
6 | per struct (struct align=x) support added to genevent (partial).<br> |
| b8b5f119 |
7 | Add offset align generation for structs to genevent.<br> |
| 0c4b3d55 |
8 | <br> |
| 9 | *TODO<br> |
| 10 | Read current trace header and buffer header.<br> |
| 11 | migrate align to lttv parser.<br> |
| f5292cf8 |
12 | make lttv aware of the per facility long, void* and size_t types.<br> |

15 | Here the status of the work in progress for LTT experimental<br> |
| 16 | <br> |
| b720b182 |
17 | * Done<br> |
| b720b182 |
18 | remove ltt-headers.h<br> |
| 19 | remove ltt-log.h<br> |
| c9eaf4ed |
20 | Put trace->active later in _ltt_trace_start()<br> |
| 21 | ltt_trace_create() remove sleep in spinlock use GFP_ATOMIC kmalloc<br> |
| 1502fa62 |
22 | Fix the locking of module hooks.<br> |
| 23 | Fix the traps -> disable nested logging for now.<br> |
| 24 | Use per cpu spinlock on trace list.<br> |
| 24c78300 |
25 | Finish the control module, libltt and lttctl : netlink interface<br> |
| baffa645 |
26 | Finish integrating lttctl with lttd.<br> |
| ada84671 |
27 | fix lttctl signal waiting : use a flag.<br> |
| 4e4d11b3 |
28 | Add ltt_write_commit_counter call to genevent.<br> |
| 24c78300 |
29 | Add information in the buffer header : buffer size, etc etc...<br> |
| 30 | -> this information is so small that we can repeat it. Makes flight recorder |
| 31 | easier to decode.<br> |
| 4e4d11b3 |
32 | Add trace start structure to buffer start header.<br> |
| ada84671 |
33 | fix genevent : take no lock if num traces active is 0.<br> |
| 4e4d11b3 |
34 | Add type information per facility : it will help having a standard way |
| 35 | to understand information coming from both kernel space and user space, and deal |
| 36 | easily with 64 bits kernel with 64 and 32 bits processes (and with size_t know |
| 37 | at compile time which can differ inside the same process from one library to |
| 38 | another).<br> |
| 39 | fix structures alignment, array and sequences too. -> trace dynamic.<br> |
| 40 | add per facility alignment (inside structures).<br> |
| 41 | add control of alignment.<br> |
| 0c4b3d55 |
42 | add control for subbuffer size and number of subbuffers.<br> |
| b6dfdc9c |
43 | Add reserve - get TSC - alignment atomicity through the use of cmpxchg.<br> |
| 44 | Add configurable alignment (LTT_ALIGNMENT).<br> |
| 0c4b3d55 |
45 | <br> |
| 46 | <br> |
| 47 | * TODO<br> |
| 4e4d11b3 |
48 | add user space tracing.<br> |
| b6dfdc9c |
49 | add genevent full functionnality : alignment, array, sequences, nested |
| 50 | structures.<br> |
| 4e4d11b3 |
51 | <br> |
| 52 | <br> |
| b720b182 |
53 | <br> |
| 54 | * TODO (low priority)<br> |
| b720b182 |
55 | Integrate header generation (genevent) in kernel build system.<br> |
| c9eaf4ed |
56 | Multithreaded lttd.<br> |
| baffa645 |
57 | Find a different way to printk from instrumentation : forbidden from schedule |
| 58 | and wakeup (causes a deadlock).<br> |
| b720b182 |
59 | <br> |
| 15e89ad6 |
60 | * Need to be discussed<br> |
| b720b182 |
61 | Drop ltt-module-register and ltt-module-unregister, use exported variables.<br> |
| 62 | RelayFS ioctl interface vs control through LTT netlink interface.<br> |
| 63 | drop ltt_filter_control, use functions pointers instead.<br> |
| b720b182 |
64 | Merge facilities headers into one big header.<br> |
| 65 | Change the name of XML files from XML to something else.<br> |
| 66 | Remove ltt-base.c.<br> |
| 67 | <br> |
| 15e89ad6 |
68 | * Not planned for integration<br> |
| 4f782cda |
69 | Remove the callback struct from the trace struct.<br> |
| 15e89ad6 |
70 | <br> |
| 71 | <br> |
| b720b182 |
72 | <br> |
| 73 | * Next experimental release patch division :<br> |
