is that the chapter is a little bit more complicated.Although the NoOp Scheduler is really simple enough to be simpler than our drivers, the 120 lines of code in 2.6.27 have amply illustrated the problem.But obviously, no matter how simple it is, as long as it exists, we take it as a liability.Here we're not going to go over and over again. Lip demonstrates what benefits, difficulties, and how to connect with the international, without using the I/O

Allocating memoryDescribes how memory is used in device drivers;How best to utilize system memory resources.Kmalloc functionThe Kmalloc memory allocation engine is a powerful tool.#include void *kmalloc (size_t size, int flags);Parameter assignment means that flags can control the behavior of Kmalloc in a variety of ways.The flag Gfp_kernel indicates that the memory allocation is performed on behalf of the process running in kernel space, which means

So far, Microsoft's latest desktop operating system, Windows 7, has been officially released for more than a year, and the author has changed its computer's operating system for the first time since it was released. After more than a year of use, I am more and more confident of the windows this time, because of its efficiency and gorgeous. I can responsibly say that Windows 7 is definitely the most gorgeous Windows system ever, but that's not the issue we're going to focus on today. So on the ot

Write a Linux driver1. Build Linux driver skeletonLinux kernel requires load and unload drivers when using driversLoad driver: Set up device file, allocate memory address space, etc. module_init function processing driver initializationUninstall drive: Delete device files, free memory address space, etc. module_exit function processing exitA C program file containing the two macros of these two functions can also be seen as a Linux-powered skeleton2.

In the Linux authoring process, there are two files that we must understand and know. One of these is the Kconfig file, and the other is the makefile file. If you are familiar with it, then it is certainly necessary for the kernel to compile the. config file, in the. config file, we found that some modules were compiled into the kernel, and some just generated a module. In the middle, how do we let the kernel discover the modules we write, which we need to explain in kconfig. As for how to gener

From one point of view, the role of a device driver is to provide a mechanism, not a policy.When writing drivers, the program ape should pay particular attention to the following basic concept: When writing kernel code to access hardware, do not impose any specific policy on the user. Because different users have different needs, the driver should handle the problem of how to make the hardware available. And the problem of how to use hardware is left

1. Overview I have read Linux Device Drivers 3 (photocopy) (ldd3 for short) and I have forgotten about it. So I want to take a note of what I have read before, and focus on the comments and understanding of the Code. I am also a beginner in Linux kernel, so I will introduce every detail in the learning-driven process step by step. It is hoped that these blogs will help others, like me, find new entry in the Linux driver and kernel learning field while

Notifies the driver when a frame is receivedin a network environment, when a device (network card) receives a data frame, it needs to notify the driver to process it. There are several notification mechanisms:Polling :The kernel keeps checking to see if the device has something to say. (More resource-intensive, but in some cases the best method)Interruption:when a particular event occurs, the device driver indicates that the device has a hardware interrupt on behalf of the kernel, and the kernel

Now when you install Windows Server 2003 for your server, or when you install XP for a workstation that uses SATA raid, you need to load the associated driver from the floppy drive, but many machines do not have a floppy drive. For a server, you can install it using the boot CD from the server, but the first logical disk for the disk display will be partitioned when installed. In the past, most of the drivers for SCSI cards, RAID cards, SATA, or SAS

Taxi drivers give me an MBA From http://blog.csdn.net/psyl/archive/2006/03/17/627496.aspx I was about to rush to the airport from Xujiahui, so I ended a meeting in a hurry and searched for a taxi in front of the mercury building. A mass found me and was very professional and straight forward to me. This stops, so I am deeply shocked by the story that follows, like a vivid MBA Case Study. To be loyal to the original intention of the taxi driver, I trie

An MBA for taxi drivers One day, I rushed to the airport from Xujiahui and searched for a taxi in front of the mercury building. A "public" found me and ended up in front of me very professionally and directly. This pause gave me a story that shocked me deeply, like a vivid MBA Case Study."Where to go ...... Okay, airport. I like to do the business of the Miluo building in Xujiahui. Here I only do two places: the Miluo building and the Junyao building

Linux is a variant of the UNIX operating system, and the principle and idea of writing a driver in Linux is similar to that of other Unix systems, but it is very different for drivers in DOS or window environments. Design the driver in the Linux environment, the thought is concise, the operation is convenient, the function is also very formidable, but the support function is few, can only depend on the function in the kernel, some commonly used operat

A quick search in the Web reveals that the number of the books that are related to Windows Device drivers can be counted with the fingers of one hand. even worse, most of the books are either too old (published before or around Windows 2000) and/or not easilyReadable. Another problem is that the Windows Driver Model (WDM) is becoming more complex as time passes, so the newer books are relatively more complex to read than the older ones. Based on all o
