At present, a small number of users reflect the updated graphics driver, restart the computer, the screen resolution is very low, color quality is poor, and resolution can not be adjusted and so on (XP system).

Preface Device tree is a data structure used to describe hardware, similar to a plate-level description language, originating from OpenFirmware (of). In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation needs. But the plethora of platforms, the different hardware that led to
It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about dr

The driver can be compiled together with the kernel or separately as a module. However, to facilitate driver debugging, the driver is usually compiled in a modular manner. 1. Compile the driver in modular Mode The Linux kernel is 2.6.12 and the fl2440 driver is used as an ex
Introduction of character device driver The app uses open, read, write, and other functions to operate the underlying hardware. The driver also has corresponding functions such as Xxx_open. How to find a driver in a function depends on the driver framework.II. Building a Driver
This digest from my my book fixing "embedded Linux driver template explaining and project practice"Initially it seems that Linux device driver development involves a lot of content, and the devices that need to be driven vary widely. Actually doing a time-driven look back looks mostly like the following points:(1) classify the drive. Which type of drive to generalize first. Collation properly re-use the ker
The computer installs the new system to install the drive is the essential process, although the system can automatically identify solves some driver installment problem, but wants to completely solve the drive problem or needs to install each kind of corresponding drive, now the driver software Ling Lang everywhere lets the person not know chooses which section is good.

~IOCTL Method Overview Objective: To implement various types of hardware control through the device driver User space call prototype: int IOCTL (int fd, unsigned long cmd ,...); FD refers to the file descriptor. "... "Represents an optional parameter, use "... "You can disable the logic check during compilation. Used to use char * argp; Optional parameters can be null, integer, or pointer. When a pointer is used, an

Today, we will go to Chapter 6 advanced character driver operations in Linux Device Drivers (version 3rd. I. IOCTL In addition to reading and writing capabilities, most devices can perform operations beyond simple data transmission. Therefore, device drivers must also be able to perform various hardware control operations. these operations are often supported by the ioctl method, which has a prototype different from the user space version: int (*ioc

Summary previous we analyzed a virtual hardware network driver sample. From here we see some of the interfaces of the network devices. In fact, the function of network device driver and block device driver is similar, both sending and receiving packets (data request).Of course they are actually very different.1. IntroductionFirst, the block device has a device no
