Abstract

The invention discloses a method for realizing an interface by using a memory window. The method is applied in a computer and comprises the following steps of: when the computer is started, controlling a basic input / output system (BIOS) to map a physical memory address space of a substrate management controller to a memory address space of a computer memory so as to establish the memory window in the computer memory; and setting an interface specification of the memory window according to an interface specification of the substrate management controller so as to ensure that the substrate management controller communicates with the memory window. The invention also provides a system for realizing the interface by using the memory window.

Description

technical field [0001] The invention relates to a system and a method for realizing an interface by using a memory window. Background technique [0002] Many servers are equipped with a baseboard management controller, and the system management software on the server communicates with the firmware in the baseboard management controller through I / O (input / output) reading and writing. A (low pincount) interface or a system management bus (system management bus, SMBUS) interface outputs signals to sub-bits in the baseboard management controller. However, the disadvantage of this I / O reading and writing method is that the data transmission speed is slow, and it is not suitable for mass data transmission. Contents of the invention [0003] In view of the above, it is necessary to provide a system that utilizes the memory window to realize the interface, which can allow the computer system to transmit data through the memory window by means of ordinary memory reading and writin...
