Abstract

The invention discloses an Ethernet phy kernel driver verification method based on Linux. The Ethernet phy kernel driver verification method comprises the following steps of redefining an Ethernet phy kernel driver structural body in a user space of the Linux; simulating and loading an Ethernet phy kernel driver in a user space of the Linux; the Ethernet phy kernel driver checks and scans and is connected with related hardware equipment; simulating and calling an Ethernet phy kernel driver to initialize the hardware equipment; and executing the instruction input by the user. According to the Ethernet phy kernel driver function verification method and device, the Ethernet phy kernel driver can be subjected to function verification under the condition that the Linux kernel support is not needed, the complex work of related hardware circuit board development is simplified, and the development efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a Linux kernel drive simulation verifier and a verification method. Background technique [0002] The usual composition of the Ethernet phy kernel driver is a member that defines the phy kernel driver and related functions in the Linux kernel. This structure itself is defined in the kernel and needs the support of the Linux kernel; in addition, the function of this structure is called in the state machine of the kernel. [0003] A normal Linux kernel will perform several functions according to the defined process: [0004] a) Load the kernel driver; [0005] b) Check and scan related hardware devices; [0006] c) If the hardware device defined with the driver is detected, associate the device with the driver; [0007] d) call the driver to initialize the hardware according to the defined process; [0008] e) Perform specific operations on the hardware device according to t...
