1.1 Platform bus, equipment and drive In the Linux 2.6 device-driven model, care is being put on the bus, device, and drive of these 3 entities, and the bus binds the device and the driver. When the system registers a device, it looks for a matching

1 Linux Device models The Linux 2.5 kernel introduces a new device model designed to manage all devices on the computer in a unified way. It contains the following infrastructure: Type Description Equipment devices The device is the most basic type in this model and is organized hierarchically by the connection of the

The newly-bought notebook is usually shipped with a DOS or Linux system, due to the manufacturer's cost savings, or when we buy it for less money. (This is because if the pre-installed Windows 8.1 will cost you hundreds of dollars), this time we use a USB external optical drive or USB drive to boot the installation system Windows 7/XP prompt error: The required CD/DVD drive

need to use I2c_new_device (). Its prototype is: struct i2c_client *I2c_new_device (struct i2c_adapter *adap, struct i2c_board_info const *info); This function will use the information provided by info to create a i2c_client and bind to the i2c_adapter that the first parameter points to. The returned parameter is a i2c_client pointer. The driver can communicate directly with the device using the i2c_client
