<p class="Pp">The <code class="Nm">tda</code> 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
    <a class="Xr">envstat(8)</a> interface, and AC adapter and lid switch events
    are reported via the <a class="Xr">sysmon_pswitch(9)</a> interface.</p>

<p class="Pp">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.</p>
