execute Make menuconfig In the character device, find the menu item "memdev driver", which is the driver module we just added, and select m 5. Execute in Linux-2.6.32.2 source code root directory Make modules You can generate the kernel module File memdev. Ko. So far, we have compiled the driver module. 4.

The following example describes how to add a device driver. Block devices and network devices can be processed accordingly. 1. Put the original file in the linux-2.4.x/driver/Char/; in this example, the file name is xyz. c 2. the device driver's original file must include such a function:Void xyz_init (void) {registe

First, I want to explain that the reason why I want to study class is that it can automatically create device nodes under/dev. Of course, the class also has another function, and the udev system is also used to automatically create device nodes. udev is in the user space, its automatic creation of device nodes is also dependent on the class provided by the sysfs

I believe many users after installing the Ghost Win7 will have this feeling: The Device Manager for the Win7 32-bit system always shows that this 2-device driver is not installed, and the graphics card driver is not normal, but when you want to update these drivers will go to the official website

Now that you have some understanding of VMM and VxD, let's take a look at how to write the VxD code. First, you must have Windows 95/98 Device Driver Development Kit. Window95 DDK is available only to MSDN subscribers, but Windows98 DDK can be obtained free of charge from Microsoft Company. Although Windows DDK is oriented to WDM, you can use it to develop a VxD program. You can
