<big>LTTV Roadmap<small><br>
<br>
* TODO<br>
-(2) Add support for "stop" button in event list. (disabling event request
-scheduler)<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
file.<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) Add a visual artifact : PID 0 could be named swapper instead of UNNAMED for
+cpus > 0.<br>
(4) Add event specific fields support to filter.<br>
(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>
-(10) Event filter : event.time does not work.<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>
-(4) Add Xen support.<br>
+(1) CPU Hotplug support. (Only ltt-heartbeat needs to be fixed).<br>
+(1) Add Xen support.<br>

+(1) Integrate SystemTAP logging with LTTng.<br>
+(2) Test and post to LKML Linux Kernel Markers.<br>
+(3) Change the byte pair "facility, event" id for a short combining the
+informatinon.<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) 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>

* TODO (low priority)<br>
enhance RPM packages for lttng kernel<br>
Integrate header generation (genevent) in kernel build system.<br>
-Find a different way to printk from instrumentation : forbidden from schedule
-and wakeup (causes a deadlock). -> Modify printk so it uses LTTng tracer!<br>
Export channels via network sockets instead of writing them to disk.<br>
Export buffers with time constraint for "live" visualisation. Use
ltt_force_switch periodically from a timer to insure slow channels do not
Change the name of XML files from XML to something else.<br>
Remove ltt-base.c.<br>
