Wait Queue:
In Linux driver programming, waiting queues can be used to implement blocking of processes.
The wait queue can be thought of as a container for the save process, and the process is placed in a wait queue when the process is blocked;
When the process is awakened, the process is fetched from the wait queue.

Linux Device Driver Article 4: Driver debugging methods, linux Article 4
In the previous article, we probably talked about how to write a simple character device driver. We are not a god, but there will certainly be a problem when writing code. We need to continuously debug it during the code writing process. In common c applications, we often use printf to outpu

First, build the kernel source code tree. I am using the friendly arm comes with Linux source code: linux-2.6.35.7-20120912.tgz
First copy the kernel source code linux-2.6.35.7-20120912.tgz to the Ubuntu system directory/home/liuhui8989/linuxshare
Unzip: Tar zxvf linux-2.6.35.7-20120912.tgz to get the linux-2.6.35.7 folder.

If the system needs to be re-installed in case of a computer failure, if the random drive disk is lost, such as the motherboard driver, NIC driver, and graphics card driver.
In particular, some old machines, motherboard integrated Nic, graphics card. Even if Win2000/WINXP is installed, some devices cannot be automatically driven.
In this case, we can consider u

Driver support routines (driverProgramDevelopment support routine)
Driver support routines are routines that the Windows operating system provides for kernel-mode drivers to use.Drivers do not use Microsoft Win32 routines; instead, they use the driver support routines that this section describes.The
This morning, I am going to play a game similar to running a kart under fedora, but the driver does not support 3D. So I started the Driver Installation trip early in the morning. There are a lot of online materials, but they are not practical, after finding a solution, I will share my experience with you. My uname-R is 2.6.35.6-45. fc14.i686. PAE

Setting up a real-world development environment requires the following steps:1. Declare the application to be debug in the application's manifest file;2. Open the application debugging support;For apps created through Eclipse, you can omit step 2, because debugging support for your app automatically opens when the Eclipse IDE launches the app.Note: In the application development process, to manually enable debugging support in the manifest file, it is best to turn off debugging support before th
The Driver is also known as the Device Driver.
In the modern computer architecture, the operating system does not directly deal with hardware, but communicates with hardware through drivers.
On the same computer, although the devices are the same, the drivers vary greatly due to different operating systems. However, no matter what is similar, it can be summarized into the following three points:

After the examination has passed, Android-driven learning has been broken for more than half a year, and now pick up learning, review the general framework of Android Drive.The core of the Android system is Java, which has a David virtual machine. Android-app operating hardware is also equivalent to Java operating hardware.Operating hardware on a Linux system is implemented via open read Write, which is the operation of C libraries. If Java can directly invoke the function in C library, it will
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 need to achieve a wide range of drivers, in fact, after a period of time to drive back looks like the main points are:(1) Classification of the drive, first summed up as which type of drive, the collation of the correct
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
After discussing the initialization and deletion of drivers for I2C devices and I2C adapters, we will focus on several function operations in file_operations, paste the file_operations struct code first. Let's see which functions are included.
Static const struct file_operations i2cdev_fops ={
The structure must be quite clear. Therefore, the I2C Driver provides the following operation functions for the user space:
1. no_llseek
2. i2cdev_read
3. i2c
