Universal intelligent platform management interface (IPMI) host to baseboard management controller (BMC) communication for non-x86 and legacy free systems
View Patent ↗Aspects of the disclosure relate to systems and methods for performing a universal Intelligent Platform Management Interface (IPMI) host-to-baseboard management controller (BMC) communication. The system includes a management device communicatively connected to a computing device through a communication link, such as a universal serial bus (USB) interface. In operation, the management device identifies itself to the computing device as a generic human interface device (HID) pipe device. Thus, a HID channel is established between the management device and the computing device through the USB interface. When the management device receives a first message from the computing device directed toward the generic HID pipe device through the HID channel, the management device may determine whether the message is an IPMI message intended for communicating with the management device. When the message is the IPMI message, the management device processes the IPMI message.
