+   in a code path. Sample before and after, the diff number of cycles.
+   When the CPU is idle it will not increase this clock counter.
+   It means that the counter is accurate if only spin-locks are used,
+   but mutexes may lead to too low values since the cpu might "idle"
+   waiting for the mutex to become available.
+   The clock source is configured on the CPU during mali module load,
+   but will not give useful output after a CPU has been power cycled.
+   It is therefore important to configure the system to not turn of
+   the cpu cores when using this functionallity.*/
