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
The ADCTSC registers are shared between the ADC Driver and the touch-screen driver. How can one register be used when processing them? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. You guys give me directions

Non-professional study notes. Thank you!
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
The general Ubuntu default contains the driver of the Intel graphics card, if not, then determine whether the graphics card is too high, such as the I7 7th generation CPU is not in Ubuntu 16.04, resulting in the screen will be very card, because the Linux 4.4 kernel does not contain Intel HD Graphics 630 driver, the workaround is only to upgrade the Linux kernel to 4.7 in Ubuntu 16.04.The following are two
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
Article title: describes the driver framework and driver loading in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

B)You can either directly send a keyboard, mouse, or other message to the game process by determining that obstacles, monsters, and other things on the map have crossed the map. Of course, killing monsters is done by simulating buttons.
However, with the destructive impact of plug-ins on the game, anti-plug-ins and plug-ins have been entangled in the kernel layer, such:

The wince application was started two years ago. However, due to division of labor, there has never been a chance to gain a deep understanding of the development of the wince Driver (including Pb-related system customization ). If it weren't for the fakegps development work that was scheduled by Ma Ning some time ago, I really don't know when to understand the wince driver development.
Fakegps is a disguise

By the way, record this blog: the Linux USB driver development of Mingyue may be available in the future.
The three important concepts of the Linux device model are bus, device, and driver. that is, bus, device, driver. In fact, the kernel also defines such data structures. They are str
How to use the platform device driver to write the driver:-------------------------------------------------------------------------1. Implement device orientation first:1) read the chip manual and obtain resources from the schematic diagram.2) construct a platform device structure and add platform Resources3) link our device resources to the device connection table of the virtual bus.
2. then implement the
Whether you're a MacBook Air or a MacBook Pro, or an imac-all-in-one series, with an Apple computer for a Windows-series system such as Windows7, the download-driven Apple driver Pack can solve all the drive problems with a single click.

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
Currently for driver developers are often faced with a problem--windows 10 drive digital signature problem, according to Symantec VeriSign Code signature China agent Shenzhen yi-dimensional letter customer service, the current issue of Symantec CodeSign also does not support Windows 10, the digital signature certificate for foreign countries already has an EV version of CodeSign, and temporarily does not support the Chinese version of the EV CodeSign.
