Problems solved by technology

[0004] At present, the graphics display compositing terminal designed based on the wayland protocol is difficult to achieve the refresh frame rate of the display device due to the structural limitation of the design. As the number of graphics application clients to be synthesized increases, the refresh frame rate drops faster, which may cause The display is not smooth, freezes and other phenomena, which affect the user experience

Abstract

The invention provides a graph synthesis method, device and system based on a wayland protocol, and the graph synthesis method based on the wayland protocol is applied to a graph display synthesis end, and comprises the steps of obtaining a kernel input event, calculating a window focus according to the kernel input event, and sending the kernel input event to a graphic application client corresponding to the window focus through an input management channel; receiving a window management request sent by at least one graphic application client through the window management channel; receiving agraphic cache drawn by the at least one graphic application client through the graphic management channel, and applying the graphic cache drawn by the at least one graphic application client to a window management request sent by the at least one graphic application client to obtain a synthesized graphic window; and outputting the synthesized graphic window to at least one display device.

Description

technical field [0001] The present application relates to terminal equipment, for example, to a method, apparatus and system for graphics synthesis based on the Wayland protocol. Background technique [0002] Wayland is a graphics display protocol (Protocol). The wayland protocol divides a graphics system into a graphics application client (client) and a graphics display compositor. The graphics application client and the graphics display compositor communicate through the wayland protocol. [0003] The graphics application client communicates with the graphics display synthesizer through an event defined by the protocol, and the graphics display synthesizer communicates with the graphics application client through a request defined by the protocol. In the Wayland protocol, there are multiple graphics application clients communicating with a graphics display compositor. [0004] At present, the graphics display synthesis terminal designed based on the wayland protocol is d...
