PCI, pci-x, pci-e differenceOne, PCI busThe PCI bus standard was developed by Pcisig in 1992 and has a history of more than 8 years. Total bandwidth =33mhzx32bit/8=133mb/s for PCI.Second, Pci-x busPci-x is based on a

Linux PCI/PCI-E Device configuration space Read and modify 1 Preface PCI and PCI Express, is a high-speed bus commonly used by computers. PCI/PCI-E device drivers and operating system cores in the operating system require access

PCI bus specifies the bus transaction that accesses the configuration space, which is called the configuration read/write transaction. Unlike the storage access transactions that use the storage address for access, the idnumber is used for addressing access to the PCI configuration space. The ID of a PCI device consists of the bus number, device number, and funct

The PCI layer and network interface cards, PCI layer and network interface cardGiven the popularity of the PCI bus, on the x86 as well as other ubuntures, we will spend a few pages on it

Interrupt mechanism of PCI busConnection between interrupt signal and interrupt ControllerConnection between interrupt signal and PCI busThe PCI bridge specification does not require the bridge to pass the interrupt request of its next PCI device. In fact, most PCI bridges a

------------- Auto Configuration -------------------- PCI provides two separate 32-bit or 64-bit address spaces corresponding to the memory and I/O port address spaces of the x86 Processor family. addresses in these address spaces are assigned by software. A third address space, called the PCI configuration space, which uses a fixed addressing scheme, allows software to determine the amount of memory and I

Solve the Problem of abnormal PCI device on IBM x346 IBM x346 server, because many PCI devices on the machine have Rom space limited by kb, The message "1801 PCI device Resource Allocation failure" is displayed at startup.

The registration and initialization process of the pci NIC Driver is implemented. the TCP/IP protocol stack and the pci protocol stack are implemented after soft interruptions occur.0x01 reason The purpose of this study is to follow the outline below: The three handshakes, data transmission, and four handshakes are debugged by the server client program. The setup environment is as follows: debug the Linux k

To understand the Linux PCI device driver, first understand that the so-called Linux PCI device driver actually includesLinux PCI device drivers and Device Drivers. I do not know whether the reader understands this sentence. I think this sentence is very important. For drivers like PCI and USB, we must understand this

Note: a good article on understanding PCI devices and PCI drivers To understand the Linux PCI device driver, first understand that the so-called Linux PCI device driver actually includes the Linux PCI device driver and the device driver. I do not know whether the reader unde

Recently looking for the PCI interface of the N more strange rare board, incidentally found that the PCI interface there are many kinds, there are long and short, is basically dizzy. So there are so many different shapes that I've found about explaining why the cards are called PCI interfaces. the difference between PCI
