Hi all, I would like to know whether it is possible or not to modify the via-pmu-led driver to make it work with the Mac mini G4 front LED, is there anything particular with this model ? By the way, why is this driver only available as in-kernel and not module ? Thanks in advance for your answer. -- Regards, Florian

Not sure. If it's a PowerMac10,1 I think it should work.

Because it's just an option of the via-pmu driver. johannes

It is a PowerMac10,1. After bypassing some device checks in via_pmu_led_init, I tried : echo 0 > /sys/class/leds/pmu-front-led/brightness which resulted in : PMU: bad reply len 85 and the brightness not changed of course. the check is in via-pmu.c line 1500 Do you know what could cause this reply ?

Hm, ok.

No, I don't really know the PMU that well. johannes

Last I tried, the usual LED control PMU command didn't work on the Mac Mini. I don't know if there's an alternative.
