fan control on macppc G5 smu

[Olivier Cherrier]

Hi,

It may not be the proper solution to control the fans on macppc smu (G5)
but the following patch allows me to work with my iMac G5 without
losing my hearing capacity ...



$ sysctl hw.sensors
hw.sensors.smu0.temp0=44.72 degC (CPU T-Diode)
hw.sensors.smu0.fan0=1530 RPM (System Fan)
hw.sensors.smu0.fan1=1530 RPM (CPU fan)
hw.sensors.smu0.fan2=1530 RPM (Hard Drive)
hw.sensors.smu0.volt0=11.87 VDC (CPU Voltage)
hw.sensors.smu0.current0=0.63 A (CPU Current)
hw.sensors.lmtemp0.temp0=51.00 degC
$

The fan range are:
smu0 at mainbus0
system: min-value: 1000
system: max-value: 4000
system: unmanage-value: 4000
cpu: min-value: 1500
cpu: max-value: 4400
cpu: unmanage-value: 4400
hd: min-value: 1800
hd: max-value: 6000
hd: unmanage-value: 6000

Thanks,
Best
