42Users must bear in mind that engine and cycle sampling are disabled by default,
43because of power saving concerns. `fdinfo` users and benchmark applications which
44query the fdinfo file must make sure to toggle the job profiling status of the
45driver by writing into the appropriate sysfs node::
46
47 echo <N> > /sys/bus/platform/drivers/panfrost/[a-f0-9]*.gpu/profiling
