Abstract

The invention relates to a UEFI (Unified Extensible Firmware Interface) firmware implementation method based on a Loongson server, and belongs to the technical field of computer firmware. Firmware is divided into a hardware abstraction layer, a firmware core layer, an equipment protocol layer and a firmware application layer, wherein the hardware abstraction layer is used for realizing the initialization of key hardware components such as a processor, an internal memory and a chipset, packaging and abstracting other board-level hardware and realizing the initialization, and also providing a function interface for accessing bottom-layer hardware equipment for an upper module; the firmware core layer is used for establishing a system service table in a UEFI to carry out the unified management of all modules in the firmware and the management of various resources; the equipment protocol layer is used for realizing various standard industrial specifications; the firmware application layer is used for realizing all functions of the firmware. The UEFI firmware implementation method can realize firmware products, with high expandability and perfect functions, meeting international mainstream UEFI firmware specifications on the Loongson server so as to support the normal start and operation of the server.

Description

technical field

[0001] The invention belongs to the technical field of computer firmware, and relates to a UEFI firmware implementation method based on a Loongson processor server computer system (hereinafter referred to as Loongson server). Background technique

[0002] UEFI (Unified Extensible Firmware Interface, Unified Extensible Firmware Interface) is an interface specification for computer firmware (or called BIOS), and it is also the most important industrial standard for firmware. The UEFI specification was originally formulated for Intel's Itanium and X86 processors, but the UEFI specification itself has nothing to do with the processor architecture, and has been applied to processor platforms such as X86, Itanium, and ARM. Computer firmware conforming to the UEFI specification (hereinafter referred to as UEFI firmware) has many advantages over traditional firmware. At present, mainstream X86 commercial computer systems basically adopt UEFI firmware.
