supermicro drivers

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.

In short, hardware drivers are distributed on the Linux kernel, and on the other hand, in the hardware a

Recently, I was looking at the driver model, but the more confused I was, the more I used to come into contact with some character drivers. I have a certain understanding of the character-driven framework. Later, I wanted to create a device file in the driver. I also learned that the sysfs file system and udev file system will inevitably involve the driver model. However, we found that the driver model has no connection with the character

) (Type) (NR) In this way, the macro value of _ IO () is obtained. The usage formats of these macros are as follows:: _ IO (magic number, base ); _ Ior (magic number, base, variable type) _ Iow (magic number, base, variable type) _ IOWR (magic number, base, variable type) Magic number)Magic number range: 0 ~ 255. Generally, the English character ""~ "Z" or ""~ "Z. The device driver obtains the magic number from the passed command, and then compares it with the magic number it processes. If

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 34.5Yuan? ", 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 am

[E liangshi Yiyou network] in the UNIX operating system, access to I/O devices is performed through a set of fixed entry points, this set of entry points are provided by the device drivers for each device. Generally, the drivers of devices provide the following entry points: 1. Open entry point. Open the device to prepare for the I/O operation. When you open a special device file, the open entry point of t

Because Windows shields the underlying system operations, the system becomes safer for users, but it brings great difficulties to many hardware or system software developers, as long as the application involves underlying operations, developers have to go deep into the Windows kernel to write system-level virtual device drivers.

Understanding mirroring, container, and storage driversTo use storage drivers more effectively, you must understand how Docker creates and stores images. Next, you need to understand how the container uses these mirrors. Finally, you need a technical introduction to both the mirror and container operators.Mirroring and Layer LayersEach Docker image references a series of read-only layers that represent the difference between file systems.

1. Preface The reason to compile the Linux kernel failed many times is to drive the wrong choice, suitable for their own native drive is not compiled into. In the face of special platform (or some neat person, I am ^_^), to compile the thin kernel, as long as the native drive, no other need. In the face of the kernel so many drivers, do not understand the hardware, we see the head big. The first time I installed Gentoo, the kernel compiled 5 times, th
