Embodiment Construction

[0020] The invention starts from the sequence of identification code allocation of Advanced Programmable Interrupt Controller (APIC), and solves the problem of identification code allocation conflict in the prior art.

[0021] Please refer to FIG. 1 , which is a system block diagram of a preferred embodiment of the present invention. This example is a computer system with 8 single-core CPUs. Among them, the first central processing unit 10, the second central processing unit 11 ... to the eighth central processing unit 17 respectively have a dedicated first local advanced programmable interrupt controller (hereinafter referred to as the first local APIC) 10a, a second local advanced The programmable interrupt controller (hereinafter referred to as the second local APIC) 11a ... the eighth local advanced programmable interrupt controller (hereinafter referred to as the eighth local APIC) 17a handles interrupt requests for each CPU respectively. At the same time, the first parti...

Abstract

The invention is an identification code configuring method for advanced programmable interrupt controllers, applied to a multiprocessor computer system, reallocating identification code of advanced programmable interrupt controller of each CPU in the initializing course, presetting partial identification codes to I / O advanced programmable interrupt controllers and updating multiprocessor configuration table in basic I / O system (BIOS) to avoid the problem of causing identification code conflict at the time of processing interrupt request of peripheral devices, and improving the stability of the multiprocessor computer system.

Description

【Technical field】 [0001] The invention relates to an identification code configuration method, in particular to an identification code configuration method for an advanced programmable interrupt controller in a multiprocessor computer system. 【Background technique】 [0002] With the advent of the information age, computer systems have become one of the indispensable tools in people's lives. In order to improve the processing efficiency of computer systems, a Symmetrical Multi-Processor (SMP) system has been developed in recent years. , when the computer system is processing a task, the speed of two processors executing the processing task in parallel is much faster than that of one processor alone. The processor is fast, and when one of the processors fails, the remaining processors can continue to take over its work to maintain the stability of the computer system. Due to the above advantages, most large workstations or server systems use a multi-processor architecture. ...
