Abstract

An embodiment discloses a share device switching control method and a portable terminal. The share device switching control method includes: acquiring a first switching command; acquiring a power state of the share device determined by a first processing system through a data channel between the first processing system and a second processing system; controlling the power state of the share device to be the power state of the share device confirmed by the first processing system according to the power state of the share device determined by the first processing system; when the control of the power state of the share device is completed, switching connection between the share device and the second processing system into connection between the share device and the second processing system by responding to the first switching command. By the share device switching control method and the portable terminal, the synchronization of the power state of the share device on both software level and hardware level is guaranteed, individual adjustment of the power state of the share device is needless and user experience is improved.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to a method for controlling switching of shared devices and a portable terminal. Background technique [0002] The portable terminal of the hybrid system architecture is based on the existing PC with only one system and embeds the PC with at least one other system. Different systems can work together to give full play to their respective advantages. Existing portable terminals with common hybrid system architecture usually integrate a master system (for example, X86 system, using windows operating system) and a slave system (for example, ARM system, using android operating system), between the main system and the slave system Can share shared devices, such as display, keyboard, mouse, camera, wireless module, etc. [0003] In the prior art, dual-system portable terminals usually share shared equipment through a switch, and in order to save power, a power switch is provided ...
