driver development software. During the development of PCI bus interface equipment, after in-depth research on the PCI bus protocol, from the perspective of the Protocol itself, the author found a convenient method for PCI configuration space operation, only simple I/o commands can be used to find a specific PCI bus device and perform read and write operations on all its configuration spaces. Once you read

I. Overview Linux network device drivers follow common interfaces. The design adopts an object-oriented method. A device is an object (net_device structure ). The most basic methods for a network device are initialization, sending, and receiving. The architecture of www.2cto. comLinux network device

Tags: SSE form must be version complex probe space replication RTOThere are two main tasks for a device driver:1. Accessing the device's memory2. Interruption of processing equipmentFor the first task. The UIO core implements the Mmap () capable of handling physical memory (physical memory), logical (logicalVirtual memory. The UiO drive is written without the need to consider these tedious details.For the s

Since the introduction of PCI bus, its unique characteristics have been favored by many vendors, which has become the mainstream of computer extension bus. At present, many domestic technical personnel have the ability to develop PCI bus interface equipment. However, the PCI bus programming technology, that is, the operation of the PCI bus device technology, has been a technical staff to feel the headache of things. The core technology of PCI bus prog

Article Title: Brief Introduction to Linux character device driver analysis. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In Linux, device drivers are organized into a set of functions for completing different tasks. These

Hardware platform: Freescale IMX6 Kernel version: kernel3.0.35 Linux's I2C subsystem is divided into three layers, I2C core layer, I2C bus driver layer and I2C device drive layer. I2C core layer is provided by kernel developers, I2C bus driver layer is provided by chip manufacturer, and I2C device

Installing device drivers is a very simple thing, many drivers in the installation when we just click the "Next" button, we can let the driver smoothly in the corresponding computer system "settled", however, when the computer system around the upgrade to the Windows Server 2008 system, How do we find that many of the device drivers simply can't be "settled" into

The two linked lists on the bus record every device and driver. How is the connection between the device and the driver? At this moment, the problem must be thrown out. Is there a device or a driver first? In the past, there were

Compile the C Operating System Device Driver-Linux general technology-Linux programming and kernel information. The following is a detailed description. 1.1 Linux Device Driver categories Linux device drivers account for a large proportion of the Linux kernel source code.

WhenInsert a device to the system, the bus of the inserted device detects the device identifier, and notifies the management center to add the device. This "device identifier" is used as a type of device.The standby feature must be used to check whether there is a proper
