<big>LTT Next Generation Roadmap<small><br>
* TODO (high priority)<br>
<BR>
(1) LTTng event description: move from tracepoint/markers to Ftrace TRACE_EVENT
- declarations. Extend TRACE_EVENT as needed. (<A HREF="mailto: Douglas Santos
-<douglas.santos@polymtl.ca">Douglas Santos</A>)<BR>
-(1) LTTng ring buffer adaptation for FTrace.<A HREF="mailto:

+# <A HREF="mailto: Douglas Santos <douglas.santos@polymtl.ca>">Douglas Santos</A>)<BR>
+(1) LTTng ring buffer adaptation for FTrace.<br>
(1) FTrace/LTTng trace format standardization.<BR>
(1) Extend NO_HZ support vs trace streaming support to other architectures (need
to add cpu idle notifiers and test).<br>
(1) Make sure ltt-ascii kernel text dump fits well with streaming hooked into
cpu idle.<br>
+[Depends on cpu idle notifier port to other architectures]<br>
(1) Support CPUs with scalable frequency with a time-consistent increment and
with an approach scalable to SMP. (done for ARM OMAP3 UP only, but the OMAP3
approach should be tested and probably derived into an SMP implementation)<br>
<br>
<br>
* Nice to have<br>
+<br>
(3) Bring stack dump in sync with new lttng.<br>
(4) Dump mounts. (to fix)<br>
(4) Add Xen support. (Trace buffer desallocation needs to be fixed)<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. (or use vmalloc_sync_all at each tracing module load)<br>
(5) Add boot time tracing support.<br>
(5) Integrate LTTng and lttd with LKCD.<br>

+* Done<br>
+<br>
+- (2009) Port LTTng to ARM OMAP3 with power management and dynamic frequency scaling
+ support. (Done by Mathieu Desnoyers, funded by Nokia).<br>
+- (2009) Improvement of trace streaming power consumption efficiency (NO_HZ
+ support) (x86 only for now).<br>
+- (2009) Periodic flush for trace streaming (Mathieu Desnoyers).<br>
+- (2009) Ascii text output from LTTng. (started by Lai Jiangshan (Fujitsu),
+ completed by Mathieu Desnoyers)<br>

<big>LTTV Roadmap<small><br>
<br>
<br>
<br>
* Nice to have<br>
+<br>
(4) Statistics per time window.<br>
(4) Add Xen per physical CPU view.<br>
(4) Add Xen per vcpu view.<br>
view into a view of the evolution of a user definable event field.<br>
<br>
* TO FIX<br>
+<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
