driver irql not less

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

One, what does the main device number and the secondary device number mean? Linu kernel is if the main device number to find the driver, the secondary device number to find the device.A: Usually a main device number represents a driver, for example, in a block device, a master device number represents a EMMC device, the different secondary device number represents a different partitionThe Linux kernel allow

The driver wizard's friends know that the driver wizard is used to repair the computer hardware software, everyone in the internet when there is a computer network card driver display is "yellow exclamation mark", and then the Web page can not open, small series encountered such a situation, this time everyone first thought must be the NIC

Now, let's write our own first character device driver--light LEDs. (Imperfect, back to perfect) Hardware platform: Exynos4412 (FS4412) Writing the drive is divided into the following steps: A--View the schematic, data manual, understand the equipment operation method; B-Find a similar driver in the kernel, develop it as a template, and sometimes need to start from scratch; C-Implement

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

Continue to drive learning based on the progress of the previous article ....... Main references: http://blog.csdn.net/dg1683wen/article/details/6861044 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. Start to build the so

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 I wrote an ADC digital-to-analog conversion driver for the embedded linux test chamber, bu

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.

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
