battery_pmu -- support for batteries and sensors in PCI-based Apple
battery* at pmu?
The battery_pmu driver provides support for batteries and hardware
sensors found in first generation PCI-based PowerBooks (i.e. Apple
Powerbook 2400, 3400 and 3500 (also known as Original PowerBook G3).
Currently it only exports a few sensors via the envsys(4) interface,
including battery charge, voltage, CPU and battery temperature and AC
envsys(4), pmu(4), envstat(8)
There is no APM emulation right now and the battery current sensor may
return misleading or wrong data. This driver is considered preliminary
and may be replaced at some point.
