<big>LTTV Roadmap<small><br>
<br>
* TODO<br>
-(2) Finish pre-computing of states to a file.<br>
(3) Add cluster support.<br>
# <A HREF="mailto:Eric Clement <eric.clement@polymtl.ca>">Eric Clement</A><br>
(3) Make LTTV aware of type formats (visual separators) defined in the XML
(4) Add a periodic event interval view. (useful to verify event periodicity)<br>
(4) create a graphical per cpu activity view.<br>
(4) Filter by target process.<br>
+(4) Compensate for time spent in probes in LTTV analysis.<br>
(4) Add CPU, network, disk, memory usage histogram. [Per interval statistics]<br>
(5) Add Python scripting hooks.<br>
+(5) Add GUI interface to take an hybrid trace.<br>
(5) Flight recorder : start lttd automatically upon GUI trace control stop.<br>
(5) Automatically detect traces with too much processes and disable faulty operations.<br>
(5) Event sequence detector (inspired from regular expressions).<br>
view into a view of the evolution of a user definable event field.<br>
<br>
* TO FIX<br>
-(4) Fix scroll backward in detailed event list (introduced with "stop"
-functionnality.<br>
(10) Add cancel button to LTTV filter GUI window.<br>
(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
<big>LTT Next Generation Roadmap<small><br>
<br>
* TODO<br>
-(3) Find a way to make logging know when it causes a minor page fault
-recursively (without ignoring silently all nested events).<br>
-(3) Have various subbuffer sizes for high and low rate channels.<br>
+(1) Integrate SystemTAP logging with LTTng.<br>
+(2) Post LTTng 0.6.x to LKML.<br>
(3) Change the byte pair "facility, event" id for a short combining the
informatinon.<br>
-(3) Add sysenter instrumentation on x86. Verify x86_64.<br>
-(3) #IBM Fix ppc64 syscall time accounting. Maybe caused by a missing syscall
-return instrumentation ?<br>
-(3) Process and kernel stack dump for x86_64, for native and compat.<br>
(4) Add Xen support.<br>

(4) efficient dynamic event filtering while recording trace.<br>
% Sensis Corp. <A HREF="mailto:Bish, Tim <Tim.Bish@Sensis.com>">Tim Bish</A><br>
(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.<br>
-(4) In flight recorder mode, have the low traffic channels saved as normal
-tracefiles and high traffic channels being flight recorder.<br>
-(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.<br>
(4) integrate NPTL instrumentation (see
<A HREF="http://nptltracetool.sourceforge.net/">PTT</A>).<br>
+(4) Probe calibration kernel module.<br>
+(4) Make page faults detect nested fault without nesting 4 times in the page
+fault handler.<br>
(5) Support CPUs with scalable frequency.<br>
+(5) Add boot time tracing support.<br>
(5) Integrate LTTng and lttd with LKCD.<br>
(7) Integrate periodical dump of perfctr hardware counters.<br>
(8) Integrate periodical dump of SystemTAP computed information.<br>
-(8) Integrate SystemTAP logging with LTTng.<br>
+(9) Rethink facility logging code (genevent output). Maybe unneeded because of
+markers/probes mechanism.<br>
(9) Add support for setjmp/longjmp and jump tables instrumentation to
ltt-instrument-functions.<br>
(9) Make ltt-usertrace-fast support internal heartbeat timer.<br>
(3) port LTTng to :<br>
