<big>LTTV Roadmap<small><br>
<br>
* TODO<br>
-(2) Finish pre-computing of states to a file.<br>
+(1) Put back coherent facility checksumming.<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
file.<br>
+ # <A HREF="mailto:Gabriel Matni <gabrien.matni@polymtl.ca>">Gabriel Matni</A><br>
(3) Use a per architecture enumeration for traps.<br>
(3) Change the byte pair "facility, event" id for a short combining the
informatinon.<br>
(4) Statistics per time window.<br>
+(4) Add Xen per physical CPU view.<br>
+(4) Add Xen per vcpu view.<br>
(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.<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>
-(1) Announce LTTng patches on LKML.<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) put probes in a hash table so we can connect the markers to them upon module
+load.<br>
+(1) efficient dynamic event filtering while recording trace.<br>

+(1) CPU Hotplug support. (Only ltt-heartbeat needs to be fixed).<br>
+ # <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>">Mathieu Desnoyers</A><br>
+(1) Add Xen support. (Trace buffer desallocation needs to be fixed)<br>

+(1) Integrate SystemTAP logging with LTTng.<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>
-(5) Discuss with RelayFS upstream to integrate LTTng modifications.<br>
-(5) Move to DebugFS for channel files.<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>
