2 Power allocator governor tunables
22 The power allocator governor implements a
24 temperature as the control input and power as the controlled output:
48      | S |-----+----->| sum e |----->| X |--->| S |-->| S |-->|power     |
60 Sustainable power
63 An estimate of the sustainable dissipatable power (in mW) should be
65 sustained power that can be dissipated at the desired control
66 temperature.  This is the maximum sustained power for allocation at
67 the desired maximum temperature.  The actual sustained power can vary
