Introduction of character device driver The app uses open, read, write, and other functions to operate the underlying hardware. The driver also has corresponding functions such as Xxx_open. How to find a driver in a function depends on the driver framework.II. Building a Driver
This digest from my my book fixing "embedded Linux driver template explaining and project practice"Initially it seems that Linux device driver development involves a lot of content, and the devices that need to be driven vary widely. Actually doing a time-driven look back looks mostly like the following points:(1) classify the drive. Which type of drive to generalize first. Collation properly re-use the ker
The computer installs the new system to install the drive is the essential process, although the system can automatically identify solves some driver installment problem, but wants to completely solve the drive problem or needs to install each kind of corresponding drive, now the driver software Ling Lang everywhere lets the person not know chooses which section is good. Small series is commonly used to dri

Today, we will go to Chapter 6 advanced character driver operations in Linux Device Drivers (version 3rd. I. IOCTL In addition to reading and writing capabilities, most devices can perform operations beyond simple data transmission. Therefore, device drivers must also be able to perform various hardware control operations. these operations are often supported by the ioctl method, which has a prototype different from the user space version: int (*ioc
NVIDIA has released Nvidia Driver 334.21, a graphics card Driver for Linux users. This new Driver supports GeForce GTX 750 Ti, GeForce GTX 750, GeForce GTX 745, and GeForce gtx titan. In addition, NVIDIA 334.21 has brought a lot of bug fixes. View the release log for details. Note: It is risky to install the video card dri
Summary previous we analyzed a virtual hardware network driver sample. From here we see some of the interfaces of the network devices. In fact, the function of network device driver and block device driver is similar, both sending and receiving packets (data request).Of course they are actually very different.1. IntroductionFirst, the block device has a device no
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
