Abstract
The invention aims to provide an initialization method of an SATA (Serial Advanced Technology Attachment) controller in a PMON (Process Monitor), which is capable of initializing the SATA controller of a south bridge and realizing the normal working of an SATA hard disk. The method comprises the step of normally initializing the SATA controller in the equipment initializing process by the PMON by ensuring the normal recognition of the south bridge SATA controller so as to normally initialize and guide the SATA hard disk.
Description
Technical field
The invention provides the implementation method of a kind of south bridge SATA controller BIOS, the implementation method of concrete a kind of south bridge SATA controller BIOS based on Godson CPU platform.
Background technology
Godson (English: Loongson) be the universal cpu that institute's independent development is calculated by the Chinese Academy of Sciences, adopt lean instruction set, be similar to the MIPS instruction set; The Basic Input or Output System (BIOS) that it adopts is the software of a kind of PMON by name.PMON is an Open Source Code Software that has BIOS and boot loader partial function concurrently, is mainly used in platforms such as MIPS, ARM, PowerPC, is different from the BIOS of X86 framework.
Godson product in the market used two types hard disk, i.e. IDE hard disk and the hard disk that is connected by IDE commentaries on classics SATA interface.The IDE hard disk can't satisfy the requirement of high-performance calculation aspect speed.And the hard disk type of main flow is the SATA hard disk in the market, uses the IDE hard disk will cause the market limitation.Change the mode that the SATA interface connects the SATA hard disk by IDE,, increased the cost of product and the complexity of software design though improved hard disk speed.
Summary of the invention
The initial method that the purpose of this invention is to provide SATA controller among a kind of PMON, it can carry out initialization to the SATA controller that south bridge carries, and realizes the operate as normal of SATA hard disk.
The implementation method of a kind of Godson blade south bridge SATA controller BIOS comprises following steps:
A, before the PCI of PMON scanning layoutprocedure, enable the SATA controller, and open main chip controls register;
B, PMON find the SATA controller in the scanning device process, and distribute I0 and MEM resource;
C, the SATA controller is set to the IDE pattern in PMON, makes calling program in the equipment disposition process SATA controller is identified as IDE equipment, and is configured;
D, according to the initialization register of South Bridge chip configuration SATA controller;
After E, the configuration successful, the SATA hard disk that is connected on the SATA controller comes the normal boot kernel according to the drive pattern of IDE hard disk;
F, in the boot kernel process, driving the operational mode of revising hard disk by SATA is AHCI, guarantees the hard disk travelling speed.
A kind of optimized technical scheme of the present invention is that said BIOS is PMON, and said SATA controller is to be integrated among the AMD SB710.

Embodiment
Following embodiment describes method of the present invention.
This example based on hardware platform be the Godson blade server.The major part of Godson blade is Godson 3A chip and AMD 780E+SB700 chipset.The main effect of PMON program is the initialization that realizes each functions of the equipments on the Godson blade, guarantees Godson blade operate as normal, and smooth pilot operationp system.
The structured flowchart of south bridge SB700 as shown in Figure 1.PMON can be divided into three parts substantially to the work of south bridge equipment: one, equipment enables; Two, the scanning of equipment and configuration; Three, the initialization of equipment.At the PMON characteristic, the present invention also is divided into three parts to the initial work of SATA controller.Shown in Figure 2 is the connected mode of SATA hard disk on the Godson blade.
1, before the PCI of PMON scanning layoutprocedure, need enable the SATA controller, and open main chip controls register.Thereby guarantee that PMON can normally find the SATA controller in the process of scanning device, and divide allotment of labor O and MEM resource.
2, the integrated SATA controller of SB700 chip internal can be operated in IDE, AHCI, three kinds of patterns of RAID, and at BIOS stage hard disk speed is not required, therefore the present invention's SATA controller in PMON is set to worker DE pattern, make calling program in the equipment disposition process, the SATA controller is identified as IDE equipment, the configuration of the aspects such as line speed of going forward side by side.
3, third part is the initialization procedure of SATA controller.The corresponding SATA controller of different South Bridge chips initialization register difference.Then the SATA controller is disposed accordingly with reference to south bridge register declaration information.After the configuration successful, the SATA hard disk that is connected on the SATA controller promptly can come the normal boot kernel according to the drive pattern of IDE hard disk.In the process of guiding kernel, driving the operational mode of revising hard disk by SATA is AHCI, thereby has guaranteed the speed of hard disk.
Claims (2)
1. the implementation method of a Godson blade south bridge SATA controller BIOS is characterized in that: comprise following steps,
A, before the PCI of PMON scanning layoutprocedure, enable the SATA controller, and open main chip controls register;
B, PMON find the SATA controller in the scanning device process, and distribute IO and MEM resource;
C, the SATA controller is set to the IDE pattern in PMON, makes calling program in the equipment disposition process SATA controller is identified as IDE equipment, and is configured;
D, according to the initialization register of South Bridge chip configuration SATA controller;
After E, the configuration successful, the SATA hard disk that is connected on the SATA controller comes the normal boot kernel according to the drive pattern of IDE hard disk;
F, in the boot kernel process, driving the operational mode of revising hard disk by SATA is AHCI, guarantees the hard disk travelling speed.
2. the implementation method of a kind of Godson blade south bridge SATA controller BIOS as claimed in claim 1, it is characterized in that: said BIOS is PMON, said SATA controller is to be integrated among the AMD SB710.
