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

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

The toolkit includes ADB and fastboot, and it also automates the installation of the latest drivers. Characteristics: Little –9.1

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

In the fourth chapter of the book "Linux device Drivers", we specialize in the debugging technology in driver development.PRINTK is just one of the techniques that requires PRINTK to print messages and write to files on disk, which slows down the entire code execution speed.There are also debugging techniques, and the effect on Code execution speed is smaller than prink.In this, we can have the driver create the file in the proc file system and write

The Windows 7 system greatly enhances the compatibility of the surrounding hardware, itself integrates a lot of drivers, including the printer, scanner, camera, mobile phone, MP3, MP4 player, etc. direct recognition, commonly used models can be used without the installation of Third-party drivers can automatically identify the use. However, occasionally unrecognized hardware, but also to install the driver,

question: I want to know what modules are built into the kernel in the Linux system and what parameters each module has. Is there a way to get a list of built-in modules and device drivers, along with their detailed information? The modern Linux kernel is growing rapidly over time to support a large number of hardware, file systems, and network functions. During this time, the introduction of the Loadable module (loadable kernel modules,[lkm]) preven

With the release of Linux2.6, the drivers for each device are rewritten to varying degrees due to the new changes made by the 2.6 kernel. For the convenience of Linux enthusiasts, I put my own share out of this worthless file. This article lists the vast majority of changes in the 2.6 kernel with previous versions, but unfortunately the use of individual functions is not listed in detail due to limited time and effort. 1.

); Read-copy-update Read-copy-update (RCU) is also an advanced mutex mechanism. Rarely used in drivers Http://www.rdrop.com/users/paulmck/rclock/intro/rclock_intro.html Optimized for situations where reads are frequent and rarely written The protected resource should be accessed through a pointer When the data structure needs to be modified, the write thread replicates first,

So let's take a look at where the Skb_release_data starts:#grep Skb_release_data./system.mapC0282AF4 T Skb_release_dataSo we know that when the system error occurs, the program pointer is c0282af4+0x74=c0282b68(2) Then use GDB to view the GDB./vmlinux (executed under the Linux directory) and enter debug mode.gdb$ b *0xc0282b68Breakpoint 1 at 0xc0282b68:file NET/CORE/SKBUFF.C, line312This is to tell us in which file, in

With this simple example code, we further clarify how the drive works.4, good, ready to work to complete, here should formally start. Write it yourself? No, or secretly lazy, online to find ready-made, there is just your chip driver, really lucky, direct use, of course, often can not be used directly, to debug under the next line.
