Install Nvidia graphics card driver in Linux: Disable The Nouveau kernel driver. Method System: Red Hat Enterprise 6 (32-bit) video card: after downloading the driver from the Nvidia official website, Nvidia Gforce 7300GT directly runs the installation in text mode. The following error message is displayed: nvidia-installer log file '/var/log/nvidia-installer.log

This time I will study the Code with the I2C driver in the kernel. Before going into the code, I will first briefly understand the relationship between the I2C core data structure. From this, we may be able to have a better understanding of the driver code. The design of the software data structure and the relationship between the data structures should at least describe the Organizational Relationship of t

USB urb (USB request block) Kernel 2.6.29.4The USB device driver code communicates with all USB devices through urb. Urb uses the struct urb structure description (include/Linux/USB. h ). Urb sends or receives data asynchronously from a specific endpoint of the same USB device. A USB device driver can allocate multiple URBS to one endpoint or reuse a single urb to multiple different endpoints Based on the d

Call other driver functions in the driver (fastcall) Author: Lai yuping (auly) aulyp@163.com In embedded systems, some communication ports are public, such as IIC ports and serial ports. Drivers of these ports are usually written by the OEM manufacturer and tested, relatively stable. We do not need to write an IIC driver when developing drivers for other devices

This kind of driver mainly presents streaming function interfaces, including XXX_Init, XXX_Deinit, XXX_Open, XXX_Close, XXX_Read, XXX_Write, XXX_Seek, XXX_IOControl, XXX_PowerUp, XXX_PowerDown, etc, note that the preceding interfaces must be output, and XXX must contain three characters. Otherwise, an error occurs. You can manually call the RegisterDevice () and DeregisterDevice () functions to load and uninstall the

Kernel 2.6.29.4 USB devices are actually complicated, but the Linux Kernel provides a subsystem called USB core to handle most of the complicated work. Therefore, the interface between the driver and USB core is described here.In the USB device organization structure, there are four layers: device, config, interface, and endpoint.A brief description of these four layers is as follows:A device usually has one or more configurations.Configuration often

Linux Device Driver Article 2: How to implement a simple hello world Driver The previous article introduced the concept of the linux driver and the basic category of the device driver in linux and the basis and differences of each category, this article describes how to write a simple test

This chapter is a concrete example of the complete process of developing and testing a Linux driver. Especially test Linux drivers. In this example of counting the number of words, the emphasis is on the implementation of the algorithm: the Linux driver, not how to count. What is the 6.1Linux drive?Linuxthe way the driver works and how it is accessed isLinuxone o

Basic Principles Through framebuffer, the application uses MMAP to map the video memory to the virtual address space of the application. The data to be displayed can be displayed on the screen after being written to the memory space; The driver allocates system memory as the memory for display; implements interfaces in the file_operations structure to serve the application; implements interfaces in the fb_ops structure to control and operate the LD

Through the first article, we already know that the whole SPI drive architecture can be divided into three parts: Protocol driver, general interface layer and controller driver. The controller driver is responsible for the data sending and receiving work at the lowest level, in order to complete the data sending and receiving work, the controller

During hardware power-on initialization, the BIOS checks all PCI devices and assigns a physical address to each device. The address is obtained and written to the configuration space of the device through the bios, And the CPU cannot be accessed directly, the driver can map this configuration space to common memory through ioremap for CPU access. When the operating system is initialized, each PCI device is assigned a pci_dev structure and the previous

After explaining the framework of the dm9000 NIC Driver in the first blog in this series, we should analyze this "giant thing" for beginners by module. This article first explains the. Driver and. Remove branches. What? I don't know what the two things are? Please first look at the younger brother this series of first blog (http://blog.csdn.net/jarvis_xian/archive/2011/06/10/6537446.aspx ).

Before we loaded the driver is the use of instdrv this application, the principle is to write the corresponding fields in the registry, this section we manually write code to load the driver, the principle is similar:The dynamic loading of a device driver is primarily done by the Service Control Manager (MANAGER,SCM) system component .
