Abstract

The invention is suitable for the technical field of desktop cloud, and provides an implementation method and device of graphics card virtualization, a desktop cloud system and a mobile terminal. The implementation method comprises the steps of calling a physical GPU by a client through a graphics card; abstracting the physical GPU into more than one VFIO virtual devices; calling one VFIO virtual device to generate a QEMU VGA device, and giving a GPU graphic processing function to a corresponding virtual desktop when the QEMU VGA device is called by a virtual machine; and by the client, displaying the content of the virtual desktop locally by using the QEMU VGA device. Through the method, requirements on a network transmission bandwidth can be reduced, and the signal transmission efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of desktop cloud, and in particular relates to a method and device for realizing virtualization of a graphics card, a desktop cloud system and terminal equipment. Background technique [0002] Desktop cloud technology uses virtualization technology to provide operating systems, desktops and applications that are not completely dependent on client terminal hardware. Desktop virtualization refers to the virtualization of the desktop of a computer to achieve the security and flexibility of desktop use. The personal desktop system on the network can be accessed from any device, at any place, and at any time. With the continuous rise of cloud computing desktop virtualization, the performance of desktop cloud terminals as access devices for desktop virtualization directly affects the user experience of end users of desktop virtualization. [0003] The working principle of the desktop cloud system is roughly as f...
