Get the kernel versionWhen the device driver needs to support different kernel versions at the same time, in the compilation phase, the kernel module needs to know the version of the currently used kernel source code to use the corresponding kernel API. In the 2.4 and 2.6 kernels, the source code header file
straightforward practice. Porting network drivers is much more difficult.Looking back at the growth of Linux along with TCP/IP, most RTOS did not consider the network until the end of 1990s. Even so, old network storage often only has basic functions. For example, you can only process a single session, access only one port at the same time, or support only physical interfaces of a single network media. In
same. such as hard disks, floppy disks, CD-ROM drives, DVD players, etc.4, the character device data or can not be randomly accessed, or can but access to random data is largely dependent on the location of the data within the device, such as tape drives5, the general device file name is irrelevant, the key is the device
Excerpt from: http://blog.chinaunix.net/uid-20799298-id-99675.htmlThe original text is writing device driver in linux:a Brief tutorial.This article focuses on three examples to explain the Linux driver, so that novice quickly, from the code layer to understand what is the Linux device driver.This article is a note, in
Tags: important contex ICA mod options map kernel variable EALLinux network devices are different from character devices and block devices, and no files correspond to network devices. The application operates the network device through the socket.The network device driver belongs to the data link layer, communicates with the IP/ARP protocol, and directly operates the physical layer chip (NIC Chip). The thre
DMA controller unsigned long claim_dma_lock (); The information that must be loaded into the controller consists of three parts: the address of the RAM, the number of atomic items that must be transmitted, and the direction of the transmission void Set_dma_mode (unsigned int channel, char mode); Mode Dma_mode_read Dma_mode_write Dma_mode_cascade Rel
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
The driver can be compiled in two ways. One is to statically compile the program into the kernel, and the other is to compile the program into a module for dynamic loading. Because uClinux does not support dynamic module loading, and embedded Linux cannot use insmod/rmmod as flexibly as Desktop Linux does, so here we will only introduce how to statically compile the dev
Recently, I have been reading books and learning about Linux device drivers. I am getting started with the simplest character device drivers and can have a macro understanding of the driver framework and functions of various elements. The following is a detailed analysis of

uses system functions to interview device files.So be sure to have a device file in your filesystem that corresponds to your device driver, so your app has access to your device drivers.Device files are typically placed below the/dev folder. You can view it through the LS command. How do I create a
Recently read a lot of kernel programming and drive development tutorials, also refer to some of the Development Board examples. The conclusion is not as high as you can imagine. Developing a driver requires a certain understanding of the kernel, not a thorough interpretation. The drivers referred to below are for specific devices and are made to work in dynamic loading of modules. The driver framework is layered, some
I have been learning device-driven programming for some time and have written several drivers. So I have a new understanding and understanding of the device driver. I have been learning device-driven programming for some time and have written several drivers. So I have a new
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 de
Linux driver module parameters-Linux Device DriversModule Parameters In many cases, we expect to control our drive behavior through parameters. For example, because of different systems, to ensure good portability of our drivers, sometimes we want to control our driven behavior by passing parameters. In this way,
Learning device driver Programming also has a period of time, also wrote a few drivers, so there are some new understanding and understanding of the device driver, summed up. Learning device driver Programming also has a period of time, also wrote a few drivers, so there are
Http://21cnbao.blog.51cto.com/109393/336263 1.1 Device Driver core layer and examples in the object-oriented programming, you can define a base class for a similar thing, specific things can inherit the functions in this base class. If the implementation of a function of the inherited object is the same as that of the base class, it can directly inherit the functions of the base class. On the contrary, it can be overloaded. This object-oriented design
