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 b

It may be difficult to put the driver model in the first chapter, but as long as the driver model can be crossed, it will be much easier later. The driver model is the cornerstone of the entire Linux Device Driver. Most people call the d
Installing device drivers is a very simple thing, many drivers in the installation when we just click the "Next" button, we can let the driver smoothly in the corresponding computer system "settled", however, when the computer system around the upgrade to the Windows Server 2008 system, How do we find that many of the device
Upper and lower modules in the Windows Device Driver framework In the device driver framework of windows, the lower-layer module provides a data structure pointer to the upper-layer module. However, upper-layer modules do not dir

Solution to failure to update the driver in Windows 8 the NVIDIA graphics card 280.26 is used as an example. Windows8 proVL 64bit 1. NVIDIA explicit drive file modification (if not NVIDIA driver, skip this step) if you directly install the nvidia
2011-03-24 Linux has been a hit recently. As a result, it is still just getting started, barely starting. But I'm glad that I finally started, and everything was hard at the beginning, especially the study of "Linux device drivers. It's also strange that I have had many activities recently. I organized "CS competitions" and bought bicycles. I often went out to ride bicycles with my classmates. In a simple summary, I spent one week in the Teaching
The Linux USB Gadget device driver can be used to implement some interesting functions. For example, 1. A storage device in an embedded product or a partition of a storage device, it can be used as a USB flash disk by PC. It can easily complete file interaction. This functio
Failure phenomenon: When the computer's system has been upgraded to Windows8.1, does the original support for Windows 8 system drivers support Windows8.1? Solution: This document will provide model information that the original Windows 8 driver can support for
Device-driven vulnerabilities are now growing to be a major threat to the security of Windows and other operating systems. This is a new field, but there are few public technical documents describing this aspect. As far as I know, the first windows Device Driver attack was m
Writing a device driver for WindowsIn order to write a device driver for Windows, one needs the device Driver Development Kit (DDK) and a C compiler.According to the article, a
the size directly here. This macro will automatically calculate the size of the data according to the parameter type datatype you provide. ==_ Iow (type, NR, datatype), write data to the driver ==_ IOWR (type, NR, datatype), bidirectional transfer, type and number members are passed as parameters Eg: # Define mem_ioc_magic 'M' // defines the magic number. Because the magic number is an 8-Bit Width, it is
Asynchronous device I/O Basics Assume that a thread sends an asynchronous I/O Request to the device. This request is sent to the device driver, which is responsible for actual I/O operations. When the driver is waiting for the response from the
