Display configuration method and device, electronic equipment and readable storage medium

Abstract

The invention provides a display configuration method and device, electronic equipment and a readable storage medium. Correct initialization of a display controller is carried out in a kernel; the method comprises the steps that a VBIOS of a video card is acquired, display configuration information corresponding to the VBIOS of the video card is acquired in a kernel, the display configuration information comprises an offset address of a display configuration register corresponding to the VBIOS and a numerical value in the display configuration register, and further firmware is reconfigured according to the display configuration information. According to the method, the display configuration information is obtained in the kernel; direct configuration, according to the method, the display configuration information is applied to the display initialization position of the firmware, so that when the display simulator in the firmware is incompatible with the VBIOS, the display controller iscorrectly initialized and the display screen is lightened under the firmware, in addition, by adopting the method, the display simulator does not need to be expanded in the firmware, and the code complexity can also be reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a display configuration method, device, electronic equipment and readable storage medium. Background technique [0002] Board solutions composed of processor chips and AMD bridge chipsets have been widely used in servers, high-performance computers, low-energy data centers, high-end desktop applications, high-throughput computing applications, industrial control, digital signal processing, and high-end embedded applications and other technical fields. In practical applications, for better human-computer interaction, most projects using board solutions will use display screens, and control the status of the display screens through the display controller in the graphics card. Correspondingly, each graphics card manufacturer will configure the graphics card's basic input and output system (VedioBasic Input Output System, referred to as: VBIOS) in the read-only memory (Rea...

AI Technical Summary

Problems solved by technology

[0003] On non-X86 platforms, the processor cannot directly run the above-mentioned VBIOS, resulting in the failure of the display controller to be correctly initialized. Further, it will cause the display screen to be off. Simulate the VBIOS operating environment to solve the above problems

[0004] In practical applications, when the display emulator in firmware is not compatible with VBIOS, the display controller still cannot be initialized correctly, so how to initialize the display correctly in firmware when the display emulator in firmware is not compatible with VBIOS The controller, to light up the display screen, is an urgent problem to be solved at present
