-The lttng patch is necessary to have the tracing hooks in the kernel.
+
+The ongoing work had the Linux Kernel Markers integrated in the mainline Linux
+kernel since Linux 2.6.24 and the Tracepoints since 2.6.28. In its current
+state, the lttng patchset is necessary to have the trace clocksource, the
+instrumentation and the LTTng high-speed data extraction mechanism added to the
+kernel.

(note : to see if the buffers has been filled, look at the dmesg output after
-lttctl -R or after stopping tracing from the GUI, it will show an event lost
+lttctl -D or after stopping tracing from the GUI, it will show an event lost
count. If it is the case, try using larger buffers. See lttctl --help to learn
how. lttv now also shows event lost messages in the console when loading a trace
with missing events or lost subbuffers.)
