Abstract

The present invention relates to the field of virtualization technologies, and in particular, to an input processing method, apparatus, and electronic device based on multiple operating systems. The method includes: when it is detected that the host operating system receives an input event, determining whether there is currently a guest operating system in a foreground running state; if present, operating the input event from the host through a preset data transmission channel The kernel space of the system injects kernel space of the guest operating system in a foreground running state such that the guest operating system of the foreground running state responds to the input event. This embodiment shortens the injection duration of input events and improves the performance of the input system in the guest operating system.

Description

【Technical field】 [0001] The invention relates to the technical field of virtualization, in particular to an input processing method, device and electronic equipment based on multiple operating systems. 【Background technique】 [0002] Based on the virtualization technology, multiple operating systems or virtual machines can run on the electronic device at the same time, and the processors, memory, and input and output devices provided by the hardware device are shared among the multiple operating systems or virtual machines. When the input method is implemented based on multiple operating systems, it is usually to open the input device node in the user space of the host operating system, receive the input event, and then judge whether the event needs to be forwarded to the guest operating system; if the event needs to be forwarded to the client The operating system injects the event into the input device module of the guest operating system kernel; the application program of...
