# amdpm(4freebsd)

AMD 756/766/768/8111 Power Management controller driver

## NAME

**amdpm** – AMD 756/766/768/8111 Power Management controller driver

## SYNOPSIS

**device** **smbus** **device** **smb** **device** **amdpm**

## DESCRIPTION

This driver provides access to AMD 756/766/768/8111 Power management controllers. Currently, only the SMBus 1.0 controller function is implemented. The SMBus 2.0 functionality of the AMD 8111 controller is supported via the [amdsmb(4)](/amdsmb/4.md) driver.

The embedded SMBus controller of the AMD 756 chipset may give you access to the monitoring facilities of your mainboard. See [smb(4)](/smb/4.md) for writing user code to fetch voltages, temperature and so on from the monitoring chip of your mainboard.

## SEE ALSO

## HISTORY

The **amdpm** driver first appeared in FreeBSD 4.5.

## AUTHORS

This driver was written by Matthew C. Forman. Based heavily on the **alpm** driver by Nicolas Souchu. This manual page was written by Murray Stokely ⟨*murray@FreeBSD.org*⟩.
