Problems solved by technology

However, the firmware in the commercial RAID card is designed for the X86 platform and is only applicable to the X86 platform
At present, domestic processor platforms such as Loongson, Shenwei, and Phytium are all non-X86 architectures. The firmware of the RAID card cannot run on these platforms, and the current domestic processor X86 platform only has the RAID card driver of the operating system layer, and there is no firmware layer. RAID card driver

Abstract

The invention discloses a Raid card firmware layer initialization method based on a domestic processor platform. The Raid card firmware layer initialization method comprises the steps of 1, judging whether a driver can run on an RAID card or not; 2, configuring RAID card related registers; 3, inquiring DMA resources needed by the RAID card, and carrying out resource allocation; 4, performing datainteraction with firmware of the RAID card, judging the state of the RAID card, and continuing command interaction when the RAID card is in a ready state; 5, carrying out basic information inquiry, inquring basic information of the RAID card comprising an RAID card controller model, firmware version information, hard disk information, RAID mode information and the like; step 6, according to the obtained RAID card information, establishing a basic command queue for the SCSI command layer to use; step 7, establishing an SCSI layer command interface; and step 8, establishing a UEFI command interface. According to the method provided by the invention, firmware layer driving of the RAID card can be carried out on X86 and non-X86 platforms of a domestic processor.

Description

technical field [0001] The invention relates to the computer field, and its main content of the invention is a Raid card firmware layer initialization method based on a domestic processor platform. Background technique [0002] Disk array (RAID) is the abbreviation of Redundant Arrays of Independent Disks. A disk array is composed of many cheaper disks combined into a large-capacity disk group, and the bonus effect generated by using individual disks to provide data improves the performance of the entire disk system. Using this technology, the data is cut into many sections and stored on each hard disk. When any hard disk in the disk array fails, the data can still be read out, and when the data is reconstructed, the data is recalculated and placed in the new hard disk. [0003] Generally, the RAID function of the storage server needs to be supported by an independent RAID card. The user connects the hard disk to the RAID card, and forms various RAID arrays through the RAID...
