Adding a driver to the android kernel is actually adding a driver to the Linux kernel. It mainly adds vertex information to two files, one is the kconfig file and the other is the MAKEFILE file. For example, if the driver you added is placed in the xxx directory under the DRIVERS directory, the kconfig and makefile files under the directory will be repaired. Spec

between the device and the drive, through the platform bus, the device and the driver is separate registration, through the platform bus probe to detect and match the device at any time, such as matching on the device driver registration;C: Due to the above advantages, a driver can be used for several similar devices;3:platform Bus and platform bus device

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

★ General IntroductionLED driver mainly realizes the hardware drive of 4 LED lights on the TQ2440 Development Board, realizes the Pin GPIOB5, GPIOB6, GPIOB7, The high and low level setting of the GPIOB8 (the configuration of the PIN is already implemented in the COMMON-SMDK.C), the driver is called with the test program, and the LED light is illuminated by command.★ Detailed INTRODUCTION 1,

At present, a small number of users reflect the updated graphics driver, restart the computer, the screen resolution is very low, color quality is poor, and resolution can not be adjusted and so on (XP system). (veterans, please ignore them directly, novice small white seriously look at the reason: update the graphics driver, the updated driver file is not proper

Preface Device tree is a data structure used to describe hardware, similar to a plate-level description language, originating from OpenFirmware (of). In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation needs. But the plethora of platforms, the different hardware that led to

It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about dr
