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

do, I have to pay 380 yuan a day, and the fuel fee is about 210 yuan. 17 hours a day, the average fixed cost of 22 yuan per hour, handed over to the company, an average of 12.5 yuan per hour oil fee. Is this 34.5 Yuan ?", I was surprised. I took a taxi for 10 years and heard a taxi driver calculate the cost for the first time. The previous drivers told me that the cost per kilometer is 0.3 yuan, and the amount of money paid every day is similar. "The

existing devices will be registered, but there are also special circumstances. For example, the kernel may need to work with an external network adapter that is not on the board, or controllers that are not attached to any bus.In general, the firmware Startup Process outputs a table of all devices on the board. If this table is not available, the only way to establish the correct device using the system startup code is to compile a kernel for a specific board. This board-specific kernel is wide

In the Linux kernel, The framebuffer (POST buffer) driver is the display driver standard. framebuffer abstracts the display device as the POST buffer. After the user maps the memory to the process address space, you can directly perform read/write operations, and write operations can be immediately displayed on the screen. Related display drivers and interfaces are available in Linux kernel/Linux/Drivers/Vi

Recently read a lot of kernel programming and drive development tutorials, also refer to some of the Development Board examples. The conclusion is not as high as you can imagine. Developing a driver requires a certain understanding of the kernel, not a thorough interpretation. The drivers referred to below are for specific devices and are made to work in dynamic loading of modules. The driver framework is layered, some

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,

One key to developing the Microsoft Hyper-V platform is to increase the performance of virtual machines by interacting with hardware. However, many system administrators are frustrated by the performance levels directly carried by Hyper-V. In fact, these performance ultimately involves understanding the I/O stack of the Virtual Machine and how it interacts with the Hyper-V hypervisor. The management program provides a fully integrated driver, called the synthesis driver, which includes 80% of th

. Specifically: Fill in a fbinfo Structure Use reigster_framebuffer (fbinfo *) to register the fbinfo structure to the kernel For the fbinfo structure, the most important thing is its fs_ops member. You need to implement interfaces in fs_ops for specific devices. Whether to use interrupt handling Memory Access If the video card does not have its own video memory, the system memory is allocated as the video memory. The graphics card comes with a vide
