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) driver.

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

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>.

BUGS

     Only polling mode is supported.

NAME

     smbus -- System Management Bus

SYNOPSIS

     device smbus

     device iicsmb
     device bktr

DESCRIPTION

     The smbus system provides a uniform, modular and architecture-independent system for the implementation of drivers to control various SMB
     devices and to utilize different SMB controllers (I2C, PIIX4, Brooktree848, vm86...).

System Management Bus
     The System Management Bus is a two-wire interface through which simple power-related chips can communicate with rest of the system.  It uses
     I2C as its backbone (see iicbus(4)).

     A system using SMB passes messages to and from devices instead of tripping individual control lines.

     With the SMBus, a device can provide manufacturer information, tell the system what its model/part number is, save its state for a suspend
     event, report different types of errors, accept control parameters, and return its status.

     The SMBus may share the same host device and physical bus as ACCESS bus components provided that an appropriate electrical bridge is provided
     between the internal SMB devices and external ACCESS bus devices.
