AMDPM(4) - Device Drivers Manual # AMDPM(4) - Device Drivers Manual
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) device.
The SMBus host interface of the AMD-756/766/768/8111 Power Management controller and NVIDIA nForce 1 chipset are also supported.
