At present, many companies have proposed new types of computer high-speed bus, such as the Arapahoe bus standard and hypertransport technology. However, the protocols are not compatible with each other and there is no unified standard. As a traditional universal local bus, PCI bus still occupies the mainstream PC market, with tenacious vitality. 　　 There are various PCI interface chips on the market, such a

PCI-Express is the latest bus and interface standard. Its original name is "I/O", which was proposed by Intel, obviously, Intel stands for the next generation of I/O interface standards. Changed to "PCI-Express" only after being certified by the PCI-SIG (pCI special interest organization ". This new standard will compl

This article is excerpted from "system virtualization: principles and implementation" PCI Bus Architecture PCI bus is a typical tree structure. Taking the host-PCI bridge in the North Bridge as the root, other PCI-PCI bridges in the bus, the

The following is an article I recently read when I wrote a pci driver. I hope it will be helpful to you. Hi, I was a beginner in linux.The driver is also difficult, and many people are asked about it shamelessly. I would like to express my gratitude and sorry to these experts, especially unix1998. The level of helplessness is limited. It may be wrong in some places. IfIf you are not reading the original text smoothly, read the original text.Original a

PCI is the abbreviation of Peripheral Component Interconnect (standard for connecting peripheral components). It is the most widely used interface in PCs, and is available in almost all motherboard products. PCI slots are also the most frequently used slots on the motherboard. on popular desktop boards, The ATX motherboard generally has 5 ~ Six PCI slots, and a s

As a common bus interface standard, PCI is widely used in computer systems. PCI provides a complet

"I know bios"->pci (pic) Lightseed 2009-5-13 1, PCI overview Note: The whole article is discussed in the PIC (8259) in the process of the process. When the PCI devices are plugged into the motherboard (which is included in the South Bridge), it wants to communicate with other devices, or let the CPU do it like this, or the CPU let it do so ... So how do they com

Because the General chip protocols are well integrated, I only need to know about them. I don't need to know the protocol too much because I don't have to do chips. The explanation here is based on the PLX 9054 (9052) chip. I am only a beginner and hope to cr

The distribution of this map by Kconfig, the PCI code should be distributed in two places, Drivers/pci and Arch/i386/pci, Taiwan belong to a China, whether drivers/pci there, or arch/i386/ PCI There, but also belong to a PCI subsy

Abstract: This paper describes the ixp425 PCI Controller structure and operation method, and then explains how to write the PCI driver for ixp425 in uboot, and finally explains how to drive the EEPRO-100 of PCI Nic. IntroductionUboot is an open-source project under SourceForge. It is short for universal bootloader, that is, the general-purpose Startup Program. B

Lspci detailed analysis using, PCI device treeI. INTRODUCTION of PCIPCI is a peripheral bus specification. Let's take a look at what a bus is: A bus is a path or channel for transmitting signals. Typically, the bus is an electrical connection to one or more conductors, and all the devices connected on the bus can receive all the transmitted content at the same time. The bus consists of an electrical interface and a programming interface. This article

Brief introduction This chapter gives a summary of a high-level bus architecture Discussion focuses on kernel functions for accessing peripheral Component interconnect (PCI, peripheral interconnect) Peripherals PCI bus is the best supported bus in the kernel This chapter mainly introduces the PCI driver if it looks for its hardware an
