lsi drivers

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

The audio system in Android is using the ALSA system architecture. Asoc--alsa System on Chip, is built on the standard ALSA drive layer, in order to better supportA software system for audio codec in embedded processors and mobile devices, ASOC is divided into three parts: machine, platform and codec in audio device drivers.Codec part: Responsible for audio decoding, this part of the code is completely non-platform-independent (the device is provided by the original), it contains some audio cont

To understand the Linux PCI device driver, first understand that the so-called Linux PCI device driver actually includesLinux PCI device drivers and Device Drivers. I do not know whether the reader understands this sentence. I think this sentence is very important. For drivers like PCI and USB, we must understand this concept, in order to understand how to look a

How to compile a Linux Device Driver 2006-12-10 16:52:36 LinuxIs a variant of the UNIX operating system. The principle and idea of writing a driver in Linux is similar to that in other UNIX systems, however, the drivers in the DoS or window environment differ greatly. In a Linux environment, the driver is designed with simple ideas, convenient operations, and powerful functions. However, it only supports a small number of functions and can only rely o

Development of uClinux drivers Basic knowledge: Kernel space ------- user space (memory application data exchange, etc) Device ---- Device Driver ----- device No. Driver category: character device block device network device Interrupt handling Driver development for uClinux and Linux is the same, but the debugging method is different. Learning driver development for uClinux is the process of learning the driver development for Linux. Linux driver debu

I have been learning device-driven programming for some time and have written several drivers. So I have a new understanding and understanding of the device driver.

Linux device driversOne, the role of device-drivenThe most popular explanation for device drivers is " Drive hardware Device Actions ". Drive and the underlying hardware directly to deal with, according to the specific work of the hardware device, read and write device registers, the completion of the device polling (polling (Polling) is a CPU decision how to provide peripheral equipment services, also known as "programmed output in" (programmed I/O).

The function of counting the number of words is encapsulated in the Linux driver. The Linux system maps each driver into a single file. These files are called device files or drive files and are stored in the/dev directory. The steps for writing a Linux driver are as follows:1. Build Linux drive skeleton (load and unload Linux drivers);2, registration and cancellation of equipment documents;3, specify the information related to the drive;4, specify th

Brief introduction The name of the TTY device is abbreviated from the previous telex, originally referred to as a physical or virtual terminal connected to a UNIX system The core of the Linux TTY driver is immediately below the standard character device driver layer and provides a range of functions that are used as interfaces by terminal type devices There are three types of TTY drivers: console, serial, and Pty /proc/tty

Hardware vendors usually update the device's drivers regularly, to modify bugs in older drivers, improve driver compatibility, and so on, in general, newer drivers often mean better performance and more reliable stability, which is what many friends see when a vendor publishes a new driver The main reason for the system driver to be updated immediately within the

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,

Reprint! Adding drivers to the Android kernel is actually adding drivers to the Linux kernel. Mainly in two files add point information, one is the Kconfig file, and the other is a makefile file. For example, you add the driver of your code into the drivers directory under the XXX directory, then repair in the directory of Kconfig files and makefile files.Specifi
