zBattery Control Methods

Object

Description

_BIF

Return static information about a battery (i.e., model number, serial

 

number, design voltage, etc.)

_BST

Returns the current battery status (i.e., dynamic information about the

 

battery such as whether the battery is currently charging, an estimate of

 

the remaining battery capacity, etc.).

_BTP

Sets the Battery Trip point, which generates an SCI when the battery(s)

 

capacity reaches the specified point

_PCL

List of pointers to the device objects representing devices powered by the

 

battery.

_STA

Returns general status of the battery (for a description of the _STA control

 

method.

3.6.2Thermal Control

ACPI allows OS to be proactive in its system cooling policies. With OS in control of the operating environment, cooling decisions can be made based on application load on the CPU and the thermal heuristics of the system. Graceful shutdown of OS at critical heat levels becomes possible as well. The following sections describe the thermal objects available to OS to control platform temperature. ACPI expects all temperatures to be given in tenths of Kelvin.

The ACPI thermal design is based around regions called thermal zones. Generally, the entire PC is one large thermal zone, but an OEM can partition the system into several thermal zones if necessary.

zActive, Passive, and Critical Policies

There are three primary cooling policies that the OS uses to control the thermal state of the hardware. The policies are Active, Passive and Critical:

−Passive cooling: The OS reduces the power consumption of the system to reduce the thermal output of the machine by slowing the processor clock. The _PSV control method is used to declare the temperature to start passive cooling.

−Active cooling: The OS takes a direct action such as turning on a fan. The _ACx control methods declare the temperatures to start different active cooling levels.

−Critical trip point: This is the threshold temperature at which the OS performs an orderly, but critical, shut down of the system. The _CRT object declares the critical temperature at which the OS must perform a critical shutdown.

When a thermal zone appears, the OS runs control methods to retrieve the three temperature points at which it executes the cooling policy. When the OS receives a thermal SCI it will run the _TMP control method, which returns the current temperature of the thermal zone. The OS checks the current temperature against the thermal event temperatures. If _TMP is greater than or equal to _ACx then the OS will turn on the associated active cooling device(s). If _TMP is greater than or equal to _PSV then the OS will perform CPU throttling. Finally if _TMP is greater than or equal to _CRT then the OS will shutdown the system.
