Hi,
I have a single processor PowerMac G5 where
the model property is PowerMac9,1.
I do have therm_pm72 and I2C_keywest option
enabled in my config. Still fans are always on.
Any thermal control driver patch available for this newer G5?
Thanks in advance for your help.
Aj

Hi !
Not yet no. This one uses a new chip called the "SMU" that replace both
the old PMU (power management) and the FCU (fan control unit). I don't
know yet how to operate it to drive the fans, there is no open source
darwin driver for it and no infos available from Apple :(
Hopefully, I'll get an iMac G5 soon, which has a similar chip, so I'll
be able to do some reverse engineering and eventually figure it out.
Ben.
