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 PCI-X interface is an updated version of the connected PCI Bus (peripheral components Interconnect), still using traditional bus technology, but there are more wiring pins, at the same time, all connected devices share all available bandwidths, as described above.
1 What is the PCI-X and the original PCI interface
1. The bus is composed of an electrical interface and a programming interface. Kernel functions used to access peripherals of Peripheral Component Interconnect (PCI, peripheral device interconnection,Because PCI bus is widely used on desktops and peripherals on larger computers today, and bus is the best supported bus in the kernel, ISA bus is basicallyIt is a "bare metal" type bus.2. Three main objectives

In 1997, PCI SIG developed the first PCI hot-Plug specification, which defines the platforms, boards, and software elements necessary to support hot-swappable. PCI SIG introduces the standard hot-swappable controller specification (SHPC spec), which clearly provides hot-swappable standard usage patterns and stringent register gr
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
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

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

The basic protocol of PCI is not introduced here. 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

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

Before debugging a pci-e MSI interrupt, you need to ensure that the traditional interrupt is tuned before debugging this. MSI interrupts the nature of a memory read-write event. The MSI address is set to one of the addresses in memory (which can be 64 bits), and the interrupt source writes MSI Data at the address where the MSI addresses are generated when an MSI interrupt occurs. That is, if there are four of the MSI disconnected, it will be written t
The PCI device has many address configuration registers, which are initialized to configure the device's bus address, and the CPU can access the resources of the device when it is configured. (Refine: Configure bus address) Other registers include registers that are not covered in this article, such as interrupt pins, middle wire breaks, and so on.

PCI device configuration space problems
Generally speaking, there are two methods to implement the PCI bus interface: one is to use a programmable device CPLD or FPGA, and the other is to use a dedicated interface chip, like the PCI9054 of PLX, ch365. The two have their own advantages and disadvantages. When using programmable devices, you can optimize the interface logic based on specific needs to achiev
