pci to pci bridge driver

IP address space of the PCI device There are three address spaces on the PCI device:Pci I/O space, PCI storage space, and PCI configuration space. The CPU can access all the address spaces on the PCI device. The I/O space and storage space are provided to the device

Original source: http://www.fpga4fun.com/PCI-Express3.htmlpacketized transactionsPCI Express is a serial bus. Or is it? From the computer ' s perspective, it's a conventional bus where read and write transactions can be achieved.The trick is and all operations are packetized. Let's assume the CPU wants to write some data to a device. It forwards the order to the PCI Express

MSI appears in PCI2.2, and PCI 3.0 allows masks to be set for each interrupt Msi-x appears in PCI3.0, relative to MSI, each device allows more interrupts, each interrupt can be configured independently Basic functions The device throws an interrupt by writing to a specific address Compared to traditional pin-based PCI interrupts: 1. Traditional PCI inter

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 setu

the mpc8548e as an example, which is determined by the definition of the MSI interrupt register of the interrupt controller );DeviceAn MSI interrupt is essentially a memory write transaction. The payload part of the transaction is composed of the value of the MSI capabilities register. The key points here are:1> device prepare the capabilities list and the MSI Node2> controller assign a value to the address register, which is inside the MSI capability node, andThe value assigned is the kernel

Sometimes, we feel that integrated sound is not good, at this time, we want to install a sound card 1, first in Taobao to buy a sound card, there is a USB interface, directly inserted on the use, today we want to use PCI-E slot independent sound card, you can computer network K song, recording, independent sound card. 2, before purchase, confirm that your computer has pci-e slot OH

1. This problem occurs we need to check the correct installation of the motherboard chip sound card driver card, and then we have an unknown device or question mark in the Device Manager, as shown in the following figure; 2. Now we open the question mark error, and then you will see in the Open interface will see: Device PCI 0 device 29 function 0; 3. Then we will see in the hardware ID as sho

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.
