SB Remote Management Interface (SB-RMI) is an SMBus compatible
|
||
|
|
interface that reports AMD SoC's Power (normalized Power) using,
|
||
|
|
Mailbox Service Request and resembles a typical 8-pin remote power
|
||
|
|
sensor's I2C interface to BMC. The power attributes in hwmon
|
||
|
|
reports power in microwatts.

of the SoC register reference. The SB-RMI address is normally 78h for
|
||
|
|
socket 0 and 70h for socket 1, but it could vary based on hardware

|
|
address select pins.
