Access to PCI and PCIe configuration space (mcfg, bus, device, Funtion)

Generally, on the X86 platform, there are two main methods to access the registers in this range: 1. Configuration mechanism 1 # or configuration Mechanism 2 # Use the in/out command for access. Note that this method is different from the general in/out command to access the pci I/O space. It introduces the address port and data port. Configuration Mechanism 2 # used only on some specific motherboard. The new design should use configuration mechanism

IP address space of the PCI device

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 driver,

At the same time, it must also tell the PCI core which devices can be driven by itself. The fo

How to obtain the pci id of a device in Linux

How to obtain the pci id of a device in Linux Sometimes, you need to use the pci ID of the device during development. For example, to bind a network card with dpdk, you need to use the pci ID of the network card. The following methods can be used to obtain the pci ID. 1. Use the lspci command. For example . 0 USB contr

How to obtain the PCI ID of a device under Linux

Sometimes, the development needs to use the device's PCI ID, such as the use of DPDK to bind a network card, need to use the PCI ID card. Here are some ways to get the PCI ID.1. Use the LSPCI command.Such as02:00.0 USB Controller:intel Corporation 82371ab/eb/mb PIIX4 usb02:01.0 Ethernet Controller:intel Corporation 82545EM Gi Gabit Ethernet Controller (Copper) (r

The difference between mSATA and mini PCI-E

Failure phenomenon: User indicates that one machine with wireless card, the consultation can remove the wireless card, the solid state drive Solution: To say mSATA and mini pci-e is not a new interface, but most of the previous integration in the system products, rarely contact. And recently with the advent of wireless and solid-state hard drives, causing concern. Mini PCI-E Interface One machine, such

Linux PCI Driver Summary

First, IntroductionThe Linux PCI driver actually consists of two parts: the PCI driver and the device itself, and the PCI driver is usually the Linux kernel, and the device itself is the driver of the developer. There are three address spaces on the PCI device: I/O space, configuration space, memory space, the CPU can

Chinese Word Segmentation technology (Chinese Word Segmentation principle)

1. Why Chinese Word Segmentation? Words are the smallest meaningful linguistic component capable of independent activities. English words use spaces as natural delimiters, while Chinese words use words as the basic unit of writing, there is no obvious distinction between words. Therefore, Chinese word analysis is the basis and key for Chinese Information Processing. The processing of Chinese in Lucene is based on the automatic

DTS configuration for PCI bus of PowerPC

During this period of time, we need to get the debugging and driver development work related to PCI Express. The old rule is that we should first look for information on the Internet. This kind of stuff is quite rare and we have already bought a book, I plan to summarize it by myself. This article describes how to configure the PCI bus in PowerPC. PowerPC uses a mechanism called FDT flat device description

There is a problem with the "SM bus controller" and "other PCI bridge devices" Driver in the Device Manager, smpci After WinXP reinstalls the system, there is a yellow question mark in the Device Manager, which is "SM bus controller" and "other PCI bridge devices".

The difference between the notebook mini pci-e and the mSATA interface

With the heat of solid-state drives, more and more friends began to pay attention to whether the notebook reserved mSATA interface, but because the mSATA interface and the mini pci-e look exactly the same, the problem will follow. Mini PCI-E from its name can be seen, is a mini version of the Pci-e interface, using the PCI

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 Bridge which then creates a packe
