<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
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) 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>
+(4) Add sort by process priority in the control flow view (must also instrument
+priority information of the processes).<br>
+% Airbus<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>

-(4) efficient dynamic event filtering while recording trace.<br>
+(1) Dump mounts.<br>
+(1) Bring userspace tracing in sync with new lttng.<br>

-(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.<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>
+ # <A HREF="mailto:Mathieu Desnoyers <compudj@krystal.dyndns.org>">Mathieu Desnoyers</A><br>
+ - Partly implemented: per marker selection through /proc interface.<br>
+ - Must still implement per active trace filtering.<br>
+(1) Add Xen support. (Trace buffer desallocation needs to be fixed)<br>

+(1) Integrate SystemTAP logging with LTTng.<br>
+(4) instrument kernel bottom half irqsave, 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>
-(4) #IBM Test fix for ppc64 kernel 2.6.9 missing syscall return instrumentation.<br>
-(5) Discuss with RelayFS upstream to integrate LTTng modifications.<br>
-(5) Move to DebugFS for channel files.<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) Add support for setjmp/longjmp and jump tables instrumentation to
ltt-instrument-functions.<br>
(9) Make ltt-usertrace-fast support internal heartbeat timer.<br>
