Abstract

Embodiments of the invention disclose an input / output virtual resource adjustment method and apparatus, which is used for performing I / O (Input / Output) virtual resource adjustment to realize hot-plug of a CPU integrated with an IIO (Internal Input Output) module. The method comprises the steps that a first CPU detects a hotly added second CPU by calling a BIOS (Basic Input Output System), obtains initialized information of the IIO module integrated on the second CPU, and stores the initialized information in a DSDT (Differential System Description Table), wherein the initialized information is used for adjusting I / O virtual resources; and the first CPU configures the I / O virtual resources according to the initialized information in the DSDT to finish hot addition of the second CPU.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for adjusting input and output virtualization resources and a processor. Background technique [0002] The Intel X86 architecture includes a central processing unit (Central Processing Unit, referred to as CPU) or multiple CPUs. The CPU has a hot-swap function, and the CPU can be hot-removed or hot-added without shutting down the system or cutting off the power supply. , to improve the system's ability to recover from disasters in a timely manner, expandability and flexibility, etc. In addition, the architecture also includes an Input / Output Hub (IOH for short) chip, and the IOH is connected to the CPU to process read and write access requests from external devices. With the advancement and development of technology, the IOH chip is gradually integrated into the CPU to form an internal input and output module (Internal Input Output, IIO for short). After the CPU inte...
