+title: The Intelligent Platform Management Bus(IPMB) Device
+
+description: |
+  The IPMB is an I2C bus which provides interconnection between a Baseboard
+  Management Controller(BMC) and chassis electronics. The BMC sends IPMI
+  requests to intelligent controllers like Satellite Management Controller(MC)
+  devices via IPMB and the device sends responses back to the BMC.
+  This device uses an I2C slave device to send and receive IPMB messages,
+  either on a BMC or other MC. A miscellaneous device provices a user space
+  program to communicate with the kernel and the backend device. Some IPMB
+  devices only support the I2C protocol and not the SMB protocol.
+
+  IPMB communications protocol Specification V1.0
