Link to this article: Http://qikee.blogbus.com/logs/37072405.html The I/O port is the communication mode between the driver and many devices. The Linux Kernel provides an operation interface for I/O port allocation, but for PCI devices, its Configuration address space has already specified the I/O port range for it, and no additional allocation operation is required. Linux KernelProvides the following inline functions to access the I/O port:Unsigned I

The sample code provided by Zhou ligong Can PCI interface card is VC, VB and Delphi, without the example of C #. net. However, when using C # To call can APIs, these APIs are very strict in data type verification, so debugging is troublesome. After a while, I finally used C #2.0 vs.2008 to call the can API to send and receive data normally. Now the API statement is provided as follows. If you have the same requirement, you can avoid a lot of detours.P

Article title: PCI device driver design based on Linux platform. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Chapter 1 Linux device management overview 1.1 Device Category In Linux, device management has its own characteristics: abstract all hardware devices, making operations on hardware devices very similar t

A computer with a Windows XP operating system cannot be started after installing a PCI network card, only mentioning Updating ESCD and building DMI pool. Analysis Many motherboards automatically update the ESCD and DMI data saved in the BIOS chip when new accessories are installed. If this This behavior occurs when the motherboard BIOS anti-write jumper is skipped and the data cannot be updated. Elimination process Refer to the motherboard manua

Because a company's SP project needs to install a Linux computer, I volunteered to install Ubuntu for that machine, because it was used very well. However, this is a new problem in the old revolution. Because the Linux system encounters the Windows ISA proxy server, the domain user name and password cannot be used, ubuntu updates are a very headache. I installed it with LiveCD. Although the installation is complete, there is no problem with Desktop, b

Use platform Virtual Machine + fedora8 1. After the PCI to serial port driver is installed, COM (such as COM1) will be displayed in windows ); 2. When the Linux operating system is disabled, open the settings in the Virtual Machine and add a serial port. The serial port number is the same as that in windows. 3. Configure minicom on a Linux terminal and run the command: minicom-s. Select Serial Port setup Device Selection: COM1 corresponds to/dev/

computer equipment in the PCI simple Communication Controller driver display yellow exclamation point icon what to do? recently, a user after reloading the computer system, found that there is a problem with the device driver, can not be used normally.

ISA Server Usage Guide As the use of the Internet continues to expand, security and performance also face challenges. In the past only to provide us with the agency service software gradually in our requirements in front of more and more pale. What do we do? We have chosen to find new software and solutions for enterprises to surf the Internet. In the long run, we need more than just a proxy software, so that employees can access the outside world th

Before debugging a pci-e MSI interrupt, you need to ensure that the traditional interrupt is tuned before debugging this. MSI interrupts the nature of a memory read-write event. The MSI address is set to one of the addresses in memory (which can be 64 bits), and the interrupt source writes MSI Data at the address where the MSI addresses are generated when an MSI interrupt occurs. That is, if there are four of the MSI disconnected, it will be written t

The PCI device has many address configuration registers, which are initialized to configure the device's bus address, and the CPU can access the resources of the device when it is configured. (Refine: Configure bus address) Other registers include registers that are not covered in this article, such as interrupt pins, middle wire breaks, and so on.
