Description

Technical Field

[0001] This invention discloses a method for solving the display problem of NVIDIA cards on domestic platforms, which relates to the application field of domestic processor computing platforms. Background Technology

[0002] Currently, the most commonly used domestically produced CPUs on desktop platforms are Phytium and Loongson processors. With technological advancements, the processing performance of domestically produced CPUs has gradually reached a usable level. However, because China's graphics card industry started later, and because graphics cards are technologically advanced, there is a significant gap between domestically produced and foreign graphics cards. Currently, the mainstream graphics cards abroad are AMD (A) and NVIDIA (N) cards. NVIDIA cards are significantly superior to AMD cards in terms of performance and power consumption control. However, due to the closed-source nature of NVIDIA drivers, their use on domestic platforms is restricted. This is mainly reflected in the lack of NVIDIA drivers in the BIOS display interface, preventing the BIOS from being displayed. Furthermore, the operating system does not integrate NVIDIA drivers, making it impossible to install and use domestically produced operating systems normally. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing a method to solve the display issues of NVIDIA graphics cards on domestic platforms, enabling NVIDIA graphics cards to be used normally on domestic platforms. It resolves display issues at the BIOS and operating system stages, thus enabling the normal use of NVIDIA graphics cards.

[0004] The specific solution proposed in this invention is as follows:

[0005] This invention provides a method for solving the display problem of NVIDIA cards on domestic platforms. Based on a domestic server, an NVIDIA card and a hardware display switching circuit are deployed. The hardware display switching circuit includes a display switching chip. The NVIDIA card is connected to a domestic processor via a PCIe interface. The domestic processor is connected to the display switching chip via a matching bridge chip. By checking whether the control signal output by the DisplayControlGPIO of the domestic processor is low or high, the system determines whether the input source of the display switching circuit switches to the matching bridge chip or the discrete graphics card, thereby enabling the display function of the NVIDIA card on the domestic platform.

[0006] Furthermore, the display switching circuit input source switching process of the method for solving the display problem of NVIDIA cards on domestic platforms is as follows:

[0007] When the domestic server is powered on, the BIOS starts running. Before the BIOS starts displaying, the CPU's DisplayControlGPIO is set to low level by default, and the input source of the display switching circuit is switched to the matching bridge chip.

[0008] The BIOS loads the domestically produced matching bridge chip display driver to display the BIOS interface. Settings are made through the BIOS interface. The BIOS boots the Grub.efi program in the operating system, and Grub boots the operating system.

[0009] Before Grub finishes running and loads the operating system kernel, it calls the BIOS's ExitBootServices service to terminate the boot service.

[0010] In the ExitBootServices service, the BIOS sets the CPU's DisplayControlGPIO to a high level, switching the display switching circuit input source to the dedicated graphics card. At the same time, Grub boots the operating system kernel, handing control over to the operating system, and then loads the dedicated graphics card driver under the operating system for display.

[0011] Furthermore, in the method for solving the display problem of NVIDIA cards on domestic platforms, when the server is in the BIOS code loading or BIOS settings interface, the graphics card driver loaded by the BIOS interface software is a display driver with a domestically produced matching bridge chip. The CPU sets the display-related flag bits to 0, the CPU's DisplayControlGPIO output control signal is low, and the input source of the display switching circuit is switched to a domestically produced bridge chip.

[0012] Furthermore, in the method for solving the display problem of NVIDIA cards on domestic platforms, when the server loads the operating system boot entry, the server has completed the BIOS stage, the CPU begins to read the operating system-related drivers, the CPU sets the display flag bit to 1, the CPU's DisplayControlGPIO output control signal is high, and the input source of the display switching circuit is switched to the dedicated graphics card.

[0013] This invention also provides a domestic server that solves the display problem of NVIDIA cards on domestic platforms. It deploys an NVIDIA card and a hardware display switching circuit. The hardware display switching circuit includes a display switching chip. The NVIDIA card is connected to a domestic processor via a PCIe interface. The domestic processor is connected to the display switching chip via a matching bridge chip. By checking whether the control signal output by the DisplayControlGPIO of the domestic processor is low or high, the system determines whether the input source of the display switching circuit switches to the matching bridge chip or the discrete graphics card, thereby enabling the display function of the NVIDIA card on the domestic platform.

[0014] Furthermore, the process of switching the input source of the display switching circuit in a domestic server that solves the display problem of NVIDIA cards on domestic platforms is as follows:

[0015] When the domestic server is powered on, the BIOS starts running. Before the BIOS starts displaying, the CPU's DisplayControlGPIO is set to low level by default, and the input source of the display switching circuit is switched to the matching bridge chip.

[0016] The BIOS loads the domestically produced matching bridge chip display driver to display the BIOS interface. Settings are made through the BIOS interface. The BIOS boots the Grub.efi program in the operating system, and Grub boots the operating system.

[0017] Before Grub finishes running and loads the operating system kernel, it calls the BIOS's ExitBootServices service to terminate the boot service.

[0018] In the ExitBootServices service, the BIOS sets the CPU's DisplayControlGPIO to a high level, switching the display switching circuit input source to the dedicated graphics card. At the same time, Grub boots the operating system kernel, handing control over to the operating system, and then loads the dedicated graphics card driver under the operating system for display.

[0019] Furthermore, in the aforementioned domestic server that solves the display problem of NVIDIA cards on domestic platforms, when the server is in the BIOS code loading or BIOS settings interface, the graphics card driver loaded by the BIOS interface software is a display driver with a domestically produced matching bridge chip, the CPU sets the display-related flag bits to 0, the CPU's DisplayControlGPIO output control signal is low, and the input source of the display switching circuit is switched to a domestically produced bridge chip.

[0020] Furthermore, in the aforementioned domestic server that solves the display problem of NVIDIA cards on domestic platforms, when the server loads the operating system boot entry, the server has completed the BIOS stage operation, the CPU begins to read the operating system-related drivers, the CPU sets the display flag bit to 1, the CPU's DisplayControlGPIO output control signal is at a high level, and the input source of the display switching circuit is switched to the discrete graphics card.

[0021] The advantages of this invention are:

[0022] This solution provides an integrated hardware and software solution to address the compatibility issues between domestic processors and NVIDIA graphics cards, enabling NVIDIA graphics cards to function properly on domestic platforms. It resolves display issues at the BIOS and operating system stages, ensuring the normal operation of NVIDIA cards. Attached Figure Description

At the same time, Grub boots the operating system kernel, handing control over to the operating system, and then loads the dedicated graphics card driver under the operating system for display.

The CPU sets the display-related flag bits to 0, the CPU's DisplayControlGPIO output control signal is low, and the input source of the display switching circuit is switched to the domestic bridge chip.

Refer to Table 1.

[0036] Meanwhile, to ensure that the domestic operating system supports NVIDIA graphics cards, the official NVIDIA platform operating system driver must be decompressed and installed. The driver will select the corresponding version and patch according to the kernel, extract the driver file, and package it into the operating system ISO installation package to ensure that the operating system supports normal display during the installation and use process.
