tda
— Tadpole
PMU
Tadpole PMU Version 1.33
The tda
driver provides basic support for
the Tadpole PMU found in Tadpole SPARCle and Viper systems. The status of
the AC adapter, battery, and fan are reported via the
envstat(8) interface, and
AC adapter and lid switch events are reported via the
sysmon_pswitch(9)
interface.
The battery status is reported by reading the battery voltage. Pp. The points at which the battery level becomes warning and critical are reported by the PMU, but are not directly correlated with battery voltage, so might be misreported by the driver.
