Abstract

The invention provides a baseboard management controller constructed based on an RISC-V system architecture, and the baseboard management controller comprises a processor, a memory and an external interface, which are connected through an AXI bus. The memory is used for storing an OpenBMC system, and the OpenBMC system is obtained by carrying out cross compiling on an OpenBMC software framework through an RISC-V tool chain of the RISC-V framework. The processor is used for executing the OpenBMC system stored in the memory, and a soft core source code of the processor is generated by a RocketChip generator. A baseboard management controller is constructed through an RISC-V system architecture based on an open source, and an ARM architecture needing authorization is replaced to achieve the baseboard management controller. Therefore, the baseboard management controller used by the user is not limited by a manufacturer any more, and the baseboard management controller used by the user canbe completely autonomously controlled.

Description

technical field

[0001] The invention relates to the technical field of server system management, in particular to a baseboard management controller and a construction method thereof. Background technique

[0002] The Baseboard Management Controller (BMC) is one of the core components of the server, and is usually implemented as an ASIC on the south bridge of the main board of the server, and mainly realizes the management and control functions of the entire system of the server.

[0003] The BMCs used in current servers are all implemented based on the ARM architecture. The ARM architecture has been granted intellectual property rights, so the existing BMC not only has high cost, but also cannot effectively guarantee the security. Moreover, the ARM architecture needs to be authorized to be used, so if manufacturers impose technical controls on the ARM architecture, it will have a serious impact on the server and embedded industries.

[0004] Therefore, the BMC used by the ...
