Embodiment Construction

[0034] Considering that the target driver contains independent parts with similar functions, this embodiment abstracts the repeated common parts of the target driver under various protocols to realize a unified driver platform, such as figure 2 The unified drive platform of the target end, the use of a unified drive platform is conducive to the development of new products, shortens the development cycle, and improves the reusability of modules.

[0035] The target-side driver in this embodiment includes: a hardware interface driver and a target-side unified driver platform. The target-side unified driver platform abstracts the repeated processing part in the target-side driver corresponding to each hardware interface and transmission protocol, and realizes a common API (Application Programming Interface, Application Programming Interface) function set, in this unified driver platform, the core of the target-side driver is to put most of the processing operations into the user-...

Abstract

The invention discloses a method for realizing a target end driver, which comprises the following steps: a hardware interface driver sends the received storage communication protocol command to a target end uniform driving platform; the target end uniform driving platform carries out visit control processing on the storage communication protocol command according to the types of the received storage communication protocol command; and the storage communication protocol command is executed for operating block equipment after the visit control processing is completed. The invention realizes the public part of the target end driver of various transmission protocols and hardware interfaces through the target end uniform platform, and the simplification and the speed acceleration of the target end driver development are realized, so the compatibility and the expansibility of the system are ensured.

Description

technical field [0001] The present invention relates to the technical field of block devices, in particular to a method for realizing a target end driver and the target end drive. Background technique [0002] Block devices include storage devices such as optical discs, hard disks, memory cards, and tapes. In order to realize the I / O (input and output) interactive operation of block devices, system users have to modify the operating system kernel module or purchase special hardware devices. The operation of these block devices is supported under the corresponding system. [0003] In some current operating systems, kernel code support for initiator (initiator) drivers of various storage transfer protocols has been implemented, but support for target (target) drivers is seldom. [0004] SCSI (Small Computer System Interface, Small Computer System Interface), like other interfaces, is actually a set of protocols for mutual communication between the initiator and the target in ...
