How to compile a Linux Device Driver 2006-12-10 16:52:36 LinuxIs a variant of the UNIX operating system. The principle and idea of writing a driver in Linux is similar to that in other UNIX systems, however, the drivers in the DoS or window environment differ greatly. In a Linux environment, the driver is designed with simple ideas, convenient operations, and powerful functions. However, it only supports a small number of functions and can only rely o

Development of uClinux drivers Basic knowledge: Kernel space ------- user space (memory application data exchange, etc) Device ---- Device Driver ----- device No. Driver category: character device block device network device Interrupt handling Driver development for uClinux and Linux is the same, but the debugging method is different. Learning driver development for uClinux is the process of learning the driver development for Linux. Linux driver debu

Linux device driversOne, the role of device-drivenThe most popular explanation for device drivers is " Drive hardware Device Actions ". Drive and the underlying hardware directly to deal with, according to the specific work of the hardware device, read and write device registers, the completion of the device polling (polling (Polling) is a CPU decision how to provide peripheral equipment services, also known as "programmed output in" (programmed I/O).

The function of counting the number of words is encapsulated in the Linux driver. The Linux system maps each driver into a single file. These files are called device files or drive files and are stored in the/dev directory. The steps for writing a Linux driver are as follows:1. Build Linux drive skeleton (load and unload Linux drivers);2, registration and cancellation of equipment documents;3, specify the information related to the drive;4, specify th

Brief introduction The name of the TTY device is abbreviated from the previous telex, originally referred to as a physical or virtual terminal connected to a UNIX system The core of the Linux TTY driver is immediately below the standard character device driver layer and provides a range of functions that are used as interfaces by terminal type devices There are three types of TTY drivers: console, serial, and Pty /proc/tty

Hardware vendors usually update the device's drivers regularly, to modify bugs in older drivers, improve driver compatibility, and so on, in general, newer drivers often mean better performance and more reliable stability, which is what many friends see when a vendor publishes a new driver The main reason for the system driver to be updated immediately within the

Han o Sinox not only can run Windows applications through wine, but also run Windows drivers through NDISHan o sinox using the Windows NDIS driverThe implementation method is to use Ndisgen to convert the Windows driver sys driver into a kernel module KO file, and then let the system load into the KO module can be used. The NDIS driver is responsible for simulating the conversion effort.Thanks to Bill Paul's work, Sinox has been able to "directly" sup

Differences between Linux 2.4 and kernel drivers-general Linux technology-Linux programming and kernel information. For more information, see the following. To thoroughly prevent incorrect operations on the kernel module being used, the Linux 2.4 kernel has been improved compared with the kernel in terms of loading and exporting the kernel module, this avoids system crashes (for example, forcible deletion of modules ). At the same time, when the drive
