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

Access to the character device is performed through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev directory. Device files for character device drivers can be identified by ' C ' in the first column of the ls-l command output. Block devices are also located in/dev, identified by the character ' B 'CRW-RW----1 root root 253, 0 2013-09-11 20:33 Usbmon0CRW-RW----1 root root 253, 1 2013-09-11 20:33

In the Linux device driver first: Introduction to the device driver briefly describes the character driver, this article briefly describes how to write a simple character device driver. This article draws on the source code in the LDD, realizes a hardware device-independent character device

Linux under the I2C-driven loading process, divided into I2C equipment layer, I2C adapter layer and I2C core layer The I2C device driver layer is the drive we write for a particular I2C device, and the following is the I2C-driven registration process I understand. In the I2C device driver we write, we call I2c_add_driver () to start I2C device-driven registration, which calls I2c_register_driver Complete a

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 .

1. What is Framebuffer?(1) framebuffer frame buffer (one screen data) (FB) is a virtual device in the Linux kernel, Framebuffer provides a unified standard interface display device to the application layer. Frame buffer (framebuffer)is an interface provided by Linux for display devices, a device that abstracts the graphics memory, allowing the upper-level application to read and write directly to the display buffer in graphical mode. This operation is abstract and uniform. UseYou don't have to w

One, what does the main device number and the secondary device number mean? Linu kernel is if the main device number to find the driver, the secondary device number to find the device.A: Usually a main device number represents a driver, for example, in a block device, a master device number represents a EMMC device, the different secondary device number represents a different partitionThe Linux kernel allow

1. Overviewin general, the 2.6 kernel has been initialized and mounted with a platform bus in the Sysfs file system. So when we write the platform model driver, we need to do two jobs:1: Implement platform Drive 2: Implement PLATForm Device, however There are many other small tasks that need to be implemented in the process of implementing these two tasks, as described later. The core architecture of the platform model-driven implementation process

Linux driver development-I/O memory access process, driver development-I A device usually provides a set of registers to control the device, read/write devices, and obtain the device status, including the control registers, data registers, and status registers, which may be in the I/O space, it may also be in the memory space. When it is in the I/O space, it is usually called the I/O port. When it is in the
