NAME

acpi – Advanced Configuration and Power Interface

SYNOPSIS

(in plan9.ini) *acpi=

aux/acpi [ -H ] [ -m mountpoint ] [ -s service ]

DESCRIPTION

Aux/acpi presents at mountpoint (default /dev) an interface to the ACPI. If a service is specified, the interface will be posted at /srv/service as well.

With the -H option, aux/acpi will turn off the power immediately.

The directory contains the following files.

battery

Contains one line for each battery in the system. Each line lists 12 fields: the percent charge remaining, power unit used (mW or mA), remaining capacity, last full charge capacity, design capacity, warning and low capacity values, mV separator, present voltage, design voltage, approximate time of charge left as hh:mm:ss, and the status (a string, one of unknown, critical, discharging or charging).  

cputemp

Each line provides a current temperature reading of a specific CPU.  

pmctl

Writing power off to pmctl will turn off the power.
