Abstract

The invention discloses a Godson computer-based graphics card resource allocation method and device, which are used in the field of computer resource allocation. The method provided by the present invention includes: after starting the Loongson computer, obtaining all graphics card information of the Loongson computer through the PCIe bus; creating a priority array for all graphics cards in the memory, wherein each item in the array corresponds to the priority of each graphics card level, and preset a graphics card in the array with the highest priority; traverse the array, obtain the graphics card with the highest priority, and read the information of the graphics card with the highest priority; The graphics card allocates address space. In the present invention, the priority of the data is set, so that the address space can be allocated according to the priority of the graphics card, thereby reducing the cost increased by refitting the hardware, simplifying the operation, and having good expansibility at the same time.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for configuring graphics card resources based on a Godson computer. Background technique [0002] Loongson computer is a computer with Loongson main board as the core and equipped with peripheral devices such as display devices, storage devices, and network devices. After the computer is powered on, it usually needs to scan all peripheral devices and allocate address space for peripheral devices. For Loongson computers, When multiple graphics cards are configured for it, because the address space required by the graphics card is large, and the address resources of the computer peripherals are difficult to meet the demand, the address space allocation fails. [0003] At present, in view of the address conflict of multiple graphics card devices in Loongson computers, the method of installing additional hardware is often used to select the connected graphics card, that i...
