LTTV Roadmap
* TODO
-(1) Port LTTV to genevent-new parser.
-(2) Fix bug with enums in lttv : make them use the value associated.
-(4) create a event rate graphical view : Will be useful in conjonction with the
+(3) Make LTTV aware of type formats 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
-(6) migrate align to lttv parser.
-(7) create an analysis of function time (like a precise gprof)
+(4) Add event specific fields support to filter.
+(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...).
(10) Add cancel button to LTTV filter GUI window.
LTT Next Generation Roadmap
* TODO
-(1) add genevent full functionnality : alignment, array, sequences, nested
-structures.
- # Mathieu Desnoyers
-(1) Use 2.6.14 RelayFS control files.
-(1) port LTTng to 2.6.14 kernel. (depends on genevent rewrite)
(2) add efficient and secure user space tracing. (1 month)
+ # Mathieu Desnoyers
(3) integrate LTTng State Dump : missing irq and process state.
# Jean-Hugues Deschenes
(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
-(3) port LTTng to : (depends on 2.6.14 port)
+(7) Integrate periodical dump of perfctr hardware counters.
+(8) Integrate periodical dump of SystemTAP computed information.
+(8) Integrate SystemTAP logging with LTTng.
+(3) port LTTng to :
