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

This chapter is a supplement to the previous chapter. It mainly describes how the kernel associates the driver with the device. Common Data Structures of PCI Layer Struct pci_device_id {// device identifier is used to uniquely identify a device Unsigned int vendor, device, Subvendor, subdevice, Class, class_mark; Unsigned long driver_data; }; Strcut pci_dev // PCI device, similar to the net_device structure

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

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

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

See a post on Fpga4fun on PCI-E, simple and easy to understand, suitable for the introduction, specially moved overOriginal address: http://www.fpga4fun.com/PCI-Express.htmlObjective:As PCI Express becomes common place in high-end FPGAs, let's see how easy FPGA Vendors made the technology available.In particular, we look more closely at Xilinx ' s

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

Processors has evolved to improve performance for virtualized environments and what is about I/O aspects? Discover One such I/O performance enhancement called device (or PCI) passthrough. This innovation improves performance of the PCI devices using hardware support from Intel (vt-d) or AMD (IOMMU). Platform virtualization is about sharing a Platform among the or more operating systems for more efficient u

Oracle Solaris, pci dss, and solarisdss Today on the Oracle official website to search for pci dss, unintentional search for Oracle Solaris information about pci dss (see the following url: https://docs.oracle.com/cd/E56344_01/html/E53940/makehtml-id-4.html ), The following is an excerpt: Pci dss security policy r

The recent discovery that due to PCI data transmission error caused IO request to get the wrong information, this phenomenon let us think, why the system has been found PCI errors, IO Request can also be the right end? According to the usual thinking, PCI transfer error, IO request should be fail off, but the fact is not the case. Does this problem have anything

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 motherboard is Rainbow 7 and the chipset is geForce 7025, nanqiao is nForce 630a, And it is useless to use the motherboard driver of the rai

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
