  • System and method for managing, resetting and diagnosing failures of a device management bus
    Patent number: 10846159
    Abstract: Embodiments are described for operating a device management bus coupled to a remote access controller and a managed device. The remote access controller detects an inoperable state of the bus and determines a FRU (Field Replaceable Unit) memory is accessible on the managed device. A predefined reset indicator is written to the FRU memory. The managed device monitors for the reset indicator being written to a specified location in FRU memory. Upon detecting the reset indicator in FRU memory, the managed device resets a bus controller coupled to the device management bus and transmits a reset notification on the device management bus. The remote access controller may include an I2C shim that controls access to an I2C multiplexer utilized for transmitting I2C commands from a service processor and an I2C coprocessor, preventing certain inoperable bus states due to concurrent operation of the I2C multiplexer by the I2C coprocessor and the service processor.

  • Apparatus and Method for Monitoring Insertion and Removal of Devices
    Publication number: 20200081628
    Abstract: A method includes establishing a register, and receiving a write command sent via a bus. A value of the register may be incremented in response to the write command, and a count of insertions of a device inferred based on the value of the register.
