-LTTV Roadmap
-
-* TODO
-(4) create a event rate graphical view : Will be useful in conjonction with the - filter.
-(6) migrate align to lttv parser.
-(7) create an analysis of function time (like a precise gprof)
- -> with gcc -f inline-functions
-
-
-* Done
-Buffer aligned on page boundary -> use valloc.
-per struct (struct align=x) support added to genevent (partial).
-Add offset align generation for structs to genevent.
-make lttv aware of the per facility long, void* and size_t types.
-Read current trace header and buffer header.
-redo lib tracefile : too much problems in there.
-modify the rest of LTTV to match the API changes.

-LTT Next Generation Roadmap
-
-* TODO
-(1) create RPM packages for lttng kernel -(1) make LTT tracing code completely atomic (thus remove locks)
-(2) add efficient and secure user space tracing. (1 month)
-(3) integrate LTTng State Dump : missing irq and process state.
-(9) add genevent full functionnality : alignment, array, sequences, nested -structures.
-(7) add gcc -finstrument-functions instrumentation
-
-
-* Done
-remove ltt-headers.h
-remove ltt-log.h
-Put trace->active later in _ltt_trace_start()
-ltt_trace_create() remove sleep in spinlock use GFP_ATOMIC kmalloc
-Fix the locking of module hooks.
-Fix the traps -> disable nested logging for now.
-Use per cpu spinlock on trace list.
-Finish the control module, libltt and lttctl : netlink interface
-Finish integrating lttctl with lttd.
-fix lttctl signal waiting : use a flag.
-Add ltt_write_commit_counter call to genevent.
-Add information in the buffer header : buffer size, etc etc...
- -> this information is so small that we can repeat it. Makes flight recorder - easier to decode.
-Add trace start structure to buffer start header.
-fix genevent : take no lock if num traces active is 0.
-Add type information per facility : it will help having a standard way -to understand information coming from both kernel space and user space, and deal -easily with 64 bits kernel with 64 and 32 bits processes (and with size_t know -at compile time which can differ inside the same process from one library to -another).
-fix structures alignment, array and sequences too. -> trace dynamic.
-add per facility alignment (inside structures).
-add control of alignment.
-add control for subbuffer size and number of subbuffers.
-Add reserve - get TSC - alignment atomicity through the use of cmpxchg.
-Add configurable alignment (LTT_ALIGNMENT).
-Get ultra-precise logging with use of TSC (only) : only one do_gettimeofday -read, and then we don't want the time flow to be altered by ntp.
-Debian kernel package
-
-
-
-* TODO (low priority)
-Integrate header generation (genevent) in kernel build system.
-Multithreaded lttd.
-Find a different way to printk from instrumentation : forbidden from schedule -and wakeup (causes a deadlock).
-
-* Need to be discussed
-Drop ltt-module-register and ltt-module-unregister, use exported variables.
-RelayFS ioctl interface vs control through LTT netlink interface.
-drop ltt_filter_control, use functions pointers instead.
-Merge facilities headers into one big header.
-Change the name of XML files from XML to something else.
-Remove ltt-base.c.
-
-* Not planned for integration
-Remove the callback struct from the trace struct.
