# amdpm(4)

AMD-756/766/768/8111 Power Management and SMBus controller

## NAME

**amdpm** – AMD-756/766/768/8111 Power Management and SMBus controller

## SYNOPSIS

**amdpm\* at pci?** **iic\* at amdpm?**

## DESCRIPTION

The **amdpm** driver provides support for the AMD-756/766/768/8111 Power Management controller.

The RNG function of the AMD-768/8111 Power Management controller is supported. Data generated by the RNG get fed into the pool of the [random(4)](/random/4.md) device.

The SMBus host interface of the AMD-756/766/768/8111 Power Management controller and NVIDIA nForce 1 chipset are also supported. The SMBus host interface can be used with the [iic(4)](/iic/4.md) framework.

## SEE ALSO

[iic(4)](/iic/4.md), [intro(4)](/intro/4.md), [pci(4)](/pci/4.md), [random(4)](/random/4.md)

## HISTORY

The **amdpm** device driver appeared in OpenBSD 3.2. SMBus host interface support was added in OpenBSD 3.9.
