ACPI Power Meter
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.
The acpipmtr
device driver appeared in
NetBSD 6.0.
The acpipmtr
driver is experimental.
