PCI, CPCI, cpcieDifferences and features CPCI bus • As a local bus of the processor system, the PCI bus is designed to connect external devices, rather than the system bus used as the processor, to connect the cache and primary storage. • (1) PCI bus space and processor space isolation • (2)ScalabilityBridge • (3)Dynamic configuration mechanism plug-and-play • (

1. Key data structure PCI devices have three address spaces: PCI I/O space, PCI storage space, and PCI configuration space. The CPU can access all address spaces on the PCI device, where I/O space and storage space are provided to the device driver, while the configuration s

PCI device driver development 1. Introduction to PCIThe PCI bus standard is a bus standard that connects external devices of the system. It is the most important bus in the PC and is actually the interface for interaction between various parts of the system. The transmission rate can reach 133 Mb/s. In the current PC architecture, almost all external devices use a variety of interface bus, which are connect

Overviewthe kernel's PCI subsystem, or PCI layer, provides a number of common features for different devices to simplify various device drivers. The important structure of the PCI layer is as follows: pci_device_iddevice identification, based on the ID defined by the PCI flag, instead of Linux Local. Pci_deva net_devi

Scope of navigation and Link Testing In web development and testing, navigation and links provide users with a rich operation experience. Users can access various types of data through navigation and links. Navigation: In the basic sense, when a user triggers this navigation operation, the user interface is directed to another target page of the current system. In other words, navigation implements the process of changing from one data page to another data page in the system, which helps users a

PCI is a widely used bus standard, it provides many superior to other bus standards (such as EISA) new features, has become the most widely used in computer systems, and the most common bus standards. Linux kernel can better support PCI bus, this paper based on the Intel 386 architecture, discusses the development of PCI device driver under Linux basic framework.

how Linux C calls the PCI Lib functionUnder Linux, you can access the configuration space of a PCI device through the "Setpci" and "SETPCI" commands, so can you use a program to access the PCI configuration space? The answer is certainly yes, there are multiple PCI libraries available under Linux for application access

Check whether the hardware supports iommu. This is a hardware function. It is called VT-D in Intel architecture. It can be seen from the BIOS that the positions of different versions are different. My website is under security-> virtualization-> VT-D. 2. Configure the kernel and support iommu There is such an option on I

In our blog post on Efficient code review, we recommend that you use a checklist. In code review, Checklist is a great tool-they ensure that the review can be done consistently across your team. They are also a convenient way to ensure that common problems can be found and resolved.Research from the Software Engineering Institute shows that programmers make 15-20 common mistakes. So by adding these errors t

Recently, a FPGA was added to the PowerPC board, and the PCI-e was debugged when a PCI-E was used to connect the board. Since VxWorks itself has already written the driver, it can be called directly during use, but soon the problem arises: at first, the MMAP method was directly used to map the FPGA bus to the application's memory space and try to read and write. This method is relatively simple and does not

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

PCI that is, Peripheral Component Interconnect , Chinese meaning" peripheral device interconnection ", by pcisig (pCI Special Interest Group) A local parallel bus standard. Currently, electronic devices are widely used. The following describes PCI the working principle of the bus is helpful to everyone.

Categories included in color and font tests Users can use Web products to obtain a large amount of data information. The information is displayed in two ways: graphics and text. Color and font play a very important role in the process of presenting images and texts to users. Reasonable and appropriate color and font settings can ensure that users can obtain the required information in the most efficient and clear way. If the color and font settings are inappropriate, the user will spend more tim

As with any complex thing, this work is often a test of the seriousness of our thinking. Just like the Pilot's checklist before takeoff, this checklist will help software designers recall clear or ambiguous specifications as they design

SafeNet, a Data Protection Enterprise, recently announced that its Luna EFT hardware security module HSM has reached the pci hsm Compliance Standard. SafeNet received this certification prior to the compliance requirements released by the Payment Card Industry Security Standards Board pci ssc, which required all financial and retail institutions to meet the level 1-12 certification standards set by

Tags: debuggingJust looking at the WinDbg in the hardware debugging of what the extended command, let me recall a job in the actual transaction.In the development process of XHCI usb3.0/3.1 IP project, we need to obtain the PCIe configuration space information similar to the actual product for the comparison reference.At the time, the XHCI host controller for similar products was connected to the SOC system through a PCIe port, and the bare metal code of the arm SOC was written to read the PCIe

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

How does the PCI NIC work? When the motherboard network card is broken or the computer needs a dual NIC, we only need to buy a PCI card installed in the motherboard, no need to replace the motherboard. The following article mainly introduces the use of PCI card installation tutorial, there is a need to install PCI card
