Character Device Driver: 1. Generally, we use APIs that dynamically allocate device numbers: Int alloc_chrdev_region (dev_t * Dev, unsigned int firstminor, unsigned int count, char * Name ); Dev is a function used for output. After successful call, the first number of the allocated range will be saved. Void unregister_chrdev_region (dev_t first, unsigned int count ); The above function allocates device numbers for

Static inline void _ list_splice (struct list_head * List, struct list_head * head)Merge the list and head of the linked list.Static inline void list_splice (struct list_head * List, struct list_head * head)When list is not empty, call _ list_splice () to merge list and head.Static inline void list_splice_init (struct list_head * List, struct list_head * head)Merge two linked lists and initialize the list.

I. Introduction to the Linux kernel module The overall structure of the Linux kernel is very large, and it contains many components. How can we include all the required parts in the kernel? One way is to compile all required functions into the kernel. This will cause two problems. One is that the generated kernel will be very large, and the other is that if we want to add or delete features in the existing kernel, We have to re-compile the kernel, work efficiency will be very low, and if the com

control panel and select "Add new hardware". Then, follow the prompts to proceed step by step. After the system check is complete, you can generally find the optical drive; 2. Go to the control panel, select "Device Manager", delete the "hard disk controller" item, and restart the computer. Because the optical drive and the hard drive use the same controller, when it is deleted and restarted, it will be automatically identified, and generally the dri

1. FramebufferThe framebuffer driver provides a basic display, and the framebuffer-driven hardware is a display controller and frame cache (one piece in the system main memory or graphics memory). The framebuffer driver provides the application with a/DEV/FBX device interface that the application implements to the display controller and frame cache by reading and writing to this device node.The following pr

whole process of tossing.1, may encounter the pit??????? I encountered a lot of pits when I installed the video driver, the following pits are limited to the Dell XPS 9560 4 K, the other models of the machine are not specifically clear:Pit One: after the installation of the system directly update the system CPU consumption 100%, basically no way to operate, about this part of the reason is not only the graphics card

the driver of the 7183 or other Blackfin acquisition chip provides a unified interface to blackfin_cam.c through struct bcap_camera_ops. The entire file shows that most of the functions are directly returned. Only the initialization functions are interesting: Static int adv7183b_init (struct i2c_client * client, u32 Arg) { Printk (kern_info "Driver for adv7183b init/N "); If (adv7183b_probe (client )){ Re
