i2c-powermac.ko is also useful for various other things on 32 bits. All the other ones in your list are indeed 64 bits only. You also need to make sure cpufreq_64 is enabled for them to work. > Also, i wonder if there is some way for detecting which machine needs which > module ? Some /proc/device-tree parsing ? Or maybe simply a /proc/cpuinfo > model matrix ? i2c-powermac.ko : should pretty much be built-in Then, it depends on the machine. The "main" modules tend to auto-load the other ones, but there is a bug where it misses windfarm_cpufreq_clamp. and windfarm_pm112 blatantly "forgets" to autoload anything. So the rule is: Machine type: - PowerMac7,2, PowerMac7,3, RackMac3,1: therm_pm72 - PowerMac8,1, PowerMac8,2: windfarm_pm81 + windfarm_cpufreq_clamp - PowerMac9,1: windfarm_pm91 + windfarm_cpufreq_clamp - PowerMac11,2: windfarm_pm112 + windfarm_cpufreq_clamp + windfarm_smu_sat + windfarm_smu_sensors + windfarm_smu_controls + windfarm_max6690_sensor.ko + windfarm_lm75_sensor.ko - PowerMac12,1: <no thermal control yet> (iMac G5 + iSight, I welcome somebody in australia giving me hardware access to one for a week or two to fix that). I'll do some patches to fix autoloading of sub-modules so that only the "main" one is needed. Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
