amdpm - AMD 756/766/768/8111 Power Management controller driver
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.
