LTTV Roadmap

* TODO
+(2) Finish pre-computing of states to a file.
+(3) Add cluster support.
+ # Eric Clement
(3) Make LTTV aware of type formats (visual separators) defined in the XML file.
(3) Use a per architecture enumeration for traps.
+(3) Change the byte pair "facility, event" id for a short combining the +informatinon.
+(4) Statistics per time window.
+(4) Disable plugins when threshold reached (i.e. too much process in control +flow view). Draw, and, when the threshold is reached, stop drawing. The global +statistics view can inhibit showing the per process stats.
+(4) Add a visual artifact : PID 0 could be named swapper instead of UNNAMED for +cpus > 0.
(4) Add event specific fields support to filter.
(4) Add a periodic event interval view. (useful to verify event periodicity)
(4) create a graphical per cpu activity view.
+(4) Add CPU, network, disk, memory usage histogram. [Per interval statistics]
(5) Add Python scripting hooks.
(5) Flight recorder : start lttd automatically upon GUI trace control stop.
(5) Automatically detect traces with too much processes and disable faulty operations.

(7) Create a hardware counter viewer (low cost rate counters : L1 cache miss, page faults, interrupts...). This will be a generalisation of the event rate view into a view of the evolution of a user definable event field.
-(10) Add cancel button to LTTV filter GUI window. +
+* TO FIX
+(4) Fix scroll backward in detailed event list (introduced with "stop" +functionnality.
+(10) Add cancel button to LTTV filter GUI window.
+(10) Sometimes, in the control flow view, a process with 0 creation time is +created in addition to the real process itself. Seems to be caused by end of +process life.
+(10) Statistics do not take in account the time spent in the mode present at +the beginning of the trace. Example : real time spent in system call on behalf +of process 0.


LTT Next Generation Roadmap

* TODO
-(3) LTTng State Dump : fix process states (currently forced to unknown).
- # Jean-Hugues Deschenes
+(3) Find a way to make logging know when it causes a minor page fault +recursively (without ignoring silently all nested events).
+(3) Have various subbuffer sizes for high and low rate channels.
+(3) Change the byte pair "facility, event" id for a short combining the +informatinon.
+(3) Add sysenter instrumentation on x86. Verify x86_64.
(4) Add Xen support.
# Mathieu Desnoyers
# Parisa Heidari
(4) efficient dynamic event filtering while recording trace.
% Sensis Corp. Tim Bish
+(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.
+(4) In flight recorder mode, have the low traffic channels saved as normal +tracefiles and high traffic channels being flight recorder.
+(4) Try to use my own non LOCK prefixed version of atomic operations : we are +using per-CPU variables, so it should make it possible.
+(4) integrate NPTL instrumentation (see +PTT).
(5) Support CPUs with scalable frequency.
(5) Integrate LTTng and lttd with LKCD.
(7) Integrate periodical dump of perfctr hardware counters.

* TODO (low priority)
enhance RPM packages for lttng kernel
Integrate header generation (genevent) in kernel build system.
-Find a different way to printk from instrumentation : forbidden from schedule -and wakeup (causes a deadlock). -> Modify printk so it uses LTTng tracer!
Export channels via network sockets instead of writing them to disk.
Export buffers with time constraint for "live" visualisation. Use ltt_force_switch periodically from a timer to insure slow channels do not
