NAME
acpipmtr — ACPI Power Meter
SYNOPSIS
acpipmtr* at acpi?
DESCRIPTION
The
acpipmtr device driver provides support for “power meters”. These are sensors that approximate the current power consumption of the system. Alternatively, a power meter may measure also the power gain when the system is connected to an external power supply.
The available information (namely, the power consumption) is made available through the envsys(4) API and the envstat(8) command.
HISTORY
The acpipmtr device driver appeared in NetBSD 6.0.
