Abstract: This application relates to an interface generation method and an electronic device. In an example interface generation method applied to a first electronic device, the first electronic device determines that content displayed in a first display area includes an interface of a first process and an interface of a second process. The method includes generating, by the first process, a first render tree used to draw the interface of the first process and generating, by the second process, a second render tree used to draw the interface of the second process. The method further includes generating, by a third process, a first target interface based on the first render tree and the second render tree. The first target interface includes the interface of the first process and the interface of the second process and is displayed in the first display area.

Abstract: Embodiments of this application disclose example methods and example apparatuses for inter-process communication, and example computer storage medium One example method in embodiments of this application includes executing a first instruction, where the first instruction instructs a first process to invoke a second process. In response to executing the first instruction, a kernel switches a context of the first process to a context of the second process based on the first instruction The second process can then be executed. The first process can be an application program in a user mode or a system program in a user mode, and the second process can be a first system program in a kernel mode.

Abstract: A refresh rate switching method and an electronic device are provided. In the method, the electronic device dynamically switches a corresponding screen refresh rate by determining whether a current display image is a high frame rate scenario or a standard frame rate scenario. In the high frame rate scenario, a relatively high screen refresh rate is used to support a high display frame rate. In this way, a user can obtain experience of the high display frame rate, and the display image is smooth without motion blur. In the standard frame rate scenario, a default low screen refresh rate is used to reduce power consumption of an entire system.
