ACPIAC(4) - Device Drivers Manual # ACPIAC(4) - Device Drivers Manual
NAME # acpiac - ACPI AC adapter
SYNOPSIS # acpiac* at acpi?
DESCRIPTION # The acpiac driver supports ACPI AC Adapters. Information about AC power source status (connected or disconnected) is available through this driver as a sensor. AC power source status is updated via an event when a change happens, if the implementation supports it. The sensors provided by acpiac can be monitored using sysctl(8) or sensorsd(8).

NAME # acpials - ACPI ambient light sensor
SYNOPSIS # acpials* at acpi?
DESCRIPTION # The acpials driver supports ACPI ambient light sensor devices and provides information about the ambient light environment in which the system is currently operating. Ambient light illuminance is read every second and can be monitored using sysctl(8) or sensorsd(8).

NAME # acpibat - ACPI control method battery
SYNOPSIS # acpibat* at acpi?
DESCRIPTION # The acpibat driver supports the ACPI Control Method Battery interface between the battery and the host. Information about the battery, such as capacity, recharge rate, voltage, and serial number, is available through this driver. Battery status is updated through an event triggered when a battery changes state (such as starting to charge) and, as a failsafe if the system does not support passing such events, every 10 seconds.

NAME # acpibtn - ACPI button
SYNOPSIS # acpibtn* at acpi?
DESCRIPTION # The acpibtn driver handles events triggered by ACPI buttons. Currently, only power button, sleep button and lid status events are supported.
The power button event is handled according to the machdep.pwraction sysctl(8). Valid values are:
0
Do nothing.
1
Perform a regular system shutdown and power off the machine if the hw.

NAME # acpicpu - ACPI processor power and performance state
SYNOPSIS # acpicpu* at acpi?
DESCRIPTION # The acpicpu driver provides support for extracting processor power and performance levels from ACPI tables. This information is used to enter deeper CPU power states when idle, and can be used to throttle processor speed to reduce power usage and extend battery life through the hw.

NAME # acpisbs - ACPI Smart Battery subsystem
SYNOPSIS # acpisbs* at acpi?
DESCRIPTION # The acpisbs driver supports the ACPI Smart Battery subsystem and provides information about the Smart Battery devices contained within it. Battery status is updated every 30 seconds, as well as in response to events from the subsystem. Battery status can be monitored using sysctl(8) or sensorsd(8).

NAME # acpitz - ACPI thermal zone
SYNOPSIS # acpitz* at acpi?
DESCRIPTION # The acpitz driver supports ACPI Thermal Zones. Temperature information is available through this driver as a sensor which is updated every 10 seconds or, if the implementation supports it, via an event. If the temperature exceeds the ‘critical’ temperature threshold, the system will be shut down and powered off.
