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

In the previous blog post, we have compiled the First_drv.ko file by makefile, which is a driver module that can be installed in Ubuntu.Execution in/work/my_drivers/first_drv/1th/directory: Insmod First_drv.koIf you are executing this command in a normal user state, you can see that the system reminds us: insmod:error inserting ' First_drv.ko ':-1 operation not permittedThis is because installing the driver

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 ).

Devices generally need to be registered before they can register the driver– Now more and more hot-pluggable devices, in turn. Register the driver first, the device is registered againEqu

The relationship between device and driver in linux driver development-Linux general technology-Linux programming and kernel information. The following is a detailed description. Yesterday I saw a piece of news titled "Housewives use LINUX". If we saw this news 10 years ago, we would be surprised to say, "I rely on it, housewives also use LINUX ", but now housewives use LINUX is not new to us because LINUX

Hyper-V Virtual Machine installation and nic cannot be found, driver cannot be installed Solution I recently used a virtual machine in win2008 and encountered some problems during use. Now I have recorded the installation process and handling methods. 1. Install hyper-V. Right-click my computer and choose manage → Server Manager → role → add role on the right → select hyper-V for Installation 2. Choose "start"> "Management Tools"> "hyper-V ". 3. First

Before analyzing the driver, we will analyze the model of the IIC subsystem. There are 2 ways to IIC device drivers, one of which is to write user-driven through a universal driver. The other is to add a IIC device driver directly to the IIC subsystem, such as a driver for AT24C02. Next we'll learn how to write a I
