-At this point, the -mm tree of the kernel is used because it has RelayFS support
-in it. In a nearby future, a vanilla kernel 2.6.14 will be used, as RelayFS has
-been integrated in the linux 2.6.14-rc series.
The following lttng patch is necessary to have the tracing hooks in the kernel.
The following ltt-control module controls the tracing.
LTTng :
supported architectures :
Intel Pentium (UP/SMP) with TSC
+ARM
+C2 Microsystems (variant of MIPS)
LTTV :
supported architectures :
Intel i386 and better
+Intel 64 bits
PowerPC
