LTTV Roadmap

* TODO
-(4) create a event rate graphical view : Will be useful in conjonction with the - filter.
- # Parisa Heidari
-(7) create an analysis of function time (like a precise gprof)
- -> with gcc -f inline-functions
-(7) Create a hardware counter viewer (rates : L1 cache miss, page faults, interrupts...).
+(3) Make LTTV aware of type formats (visual separators) defined in the XML +file.
+(3) Use a per architecture enumeration for traps.
+(4) Add event specific fields support to filter.
+(4) Add a generic 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 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
-(1) Use 2.6.14 RelayFS control files.
-(2) add efficient and secure user space tracing. (1 month)
-(3) integrate LTTng State Dump : missing irq and process state.
+(2) Make ltt-usertrace-fast support internal heartbeat timer.
+ # Mathieu Desnoyers
+(3) LTTng State Dump : fix process states (currently forced to unknown).
# Jean-Hugues Deschenes
(4) efficient dynamic event filtering while recording trace.
% Sensis Corp. Tim Bish
+(5) Support CPUs with scalable frequency.
(5) Integrate LTTng and lttd with LKCD.
-(7) add gcc -finstrument-functions instrumentation
+(6) Add Xen support.
(7) Integrate periodical dump of perfctr hardware counters.
-(3) port LTTng to : (depends on 2.6.14 port)
+(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.
+(3) port LTTng to :
