root bus is 0. In PC, the memory controller is usually integrated into the host/PCI bridge device chip. Therefore, the host/PCI bridge is also known as the "North Bridge chipset (North Bridge chipset )". 2).

Introduction to Linux PCI device drivers

roughly describe what the Linux kernel has done for us (master), and then what we should do (times ). (1) What does Linux kernel do? Simply put, the Linux kernel mainly involves enumeration and configuration of PCI devices, which are completed at the beginning of the kernel. Enumeration: For the PCI bus, a device called the PCI

Computer motherboard knowledge

"865pe motherboard", and 865pe refers to the Motherboard chipset. The Motherboard chipset usually includes both the nanqiao chip and the beiqiao chip, but some motherboard chips also contain one or three chips. The beiqiao chip mainly determines the motherboard specifications, hardware support, and system performance. It connects to the CPU, memory, and AGP bus. What CPU is supported by the main board, how fast the card is to be supported, and how of

Interrupt and interrupt handling

some bits in the shield register. You can read the Status Register to obtain the interruption in the active state of the system. Some interruptions in the system are hard-wired. For example, the periodic timer of the real-time clock may be fixed to Pin 3 of the interrupt controller. Other pins connected to the controller can only be determined by the Control card inserted into the specific ISA or

Research on interrupt Mechanism Based on PCI Bus

Abstract: The PCI bus has the plug-and-play (PNP, Plug and Play) feature, which makes the mechanism of CPU access to the expansion card significantly different from that of the plug-and-play system, particularly, the interrupt mechanism is complicated. This paper introduces in detail the interrupt Structure of High-performance PC and the interrupt mechanism of plx9052, and takes the
