18 daemon monitors the CPU load and automatically adjusts the CPU
21 All CPUs will be set to their maximum frequency when the 1 second
22 machine load exceeds 25% of one CPU.
23 All CPUs will be set to their
24 minimum frequency when the 10 second machine load drops below 12% of
27 The options are as follows:
28 .Bl -tag -width ".Fl p Ar hysteresis"
33 to not go to the background and prints some debug output to
35 .It Fl p Ar hysteresis
36 Percent of the upper limit to subtract as an hysteresis value to scale
37 down to the min frequency.
40 Disables switching to turbo mode as maximum frequency completely.
41 Switching to turbo mode as maximum frequency is enabled by default,
42 if the CPU supports it.
43 .It Fl u Ar trigger_up
44 Per CPU load limit in percent to force maximum frequency.
49 utility will exit with a non-zero code if the required sysctls are not
