LTTV Roadmap

* TODO
-(3) Make LTTV aware of type formats defined in the XML file.
+(3) Make LTTV aware of type formats (visual separators) defined in the XML +file.
(3) Use a per architecture enumeration for traps.
-(3) Integrate Kernel State Dump information.
-(4) create a event rate graphical view : Will be useful in conjunction with the - filter.
- # Parisa Heidari
+(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.
(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.
(5) Event sequence detector (inspired from regular expressions).
-(7) create an analysis of function time (like a precise gprof).
- -> with gcc -f inline-functions
-(7) Create a hardware counter viewer (low cost rate counters : L1 cache miss, page faults, interrupts...).
+(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.

LTT Next Generation Roadmap

* TODO
-(2) add efficient and secure user space tracing. (1 month)
- # Mathieu Desnoyers
-(3) integrate LTTng State Dump : missing irq and process state.
+(3) LTTng State Dump : fix process states (currently forced to unknown).
# Jean-Hugues Deschenes
+(4) Add Xen support.
+ # Mathieu Desnoyers
+ # Parisa Heidari
(4) efficient dynamic event filtering while recording trace.
% Sensis Corp. Tim Bish
-(4) Create the heartbeat timer LTTng module. Make sure that heartbeat events -never hit the facility channel. Use the complete 64 bits TSC for the facility -channel in every case. That's because this channel must never be overwritten -even in "flight recorder" mode.
+(5) Support CPUs with scalable frequency.
(5) Integrate LTTng and lttd with LKCD.
-(6) Add Xen support.
-(7) add gcc -finstrument-functions instrumentation
(7) Integrate periodical dump of perfctr hardware counters.
(8) Integrate periodical dump of SystemTAP computed information.
(8) Integrate SystemTAP logging with LTTng.
+(9) Add support for setjmp/longjmp and jump tables instrumentation to +ltt-instrument-functions.
+(9) Make ltt-usertrace-fast support internal heartbeat timer.
(3) port LTTng to :

enhance RPM packages for lttng kernel
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). -> 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 interfere with viewing.
+Have an optional round-robin mode to write information into multiple channels +from the same source.

Use 2.6.14 RelayFS control files.
