An image processing method and a computer system. The method may be applied to a cloud-side server in a cloud mobile phone. The server may be a virtualization server, a host operating system and a guest operating system are deployed on the server, a user mode graphics driver is deployed in the guest operating system, and a kernel mode graphics driver is deployed in the host operating system. The user mode graphics driver and the kernel mode graphics driver collaborate with each other to implement image rendering of the server. Then, the server may send a rendered image to the cloud mobile phone. Accordingly, an instruction translation process is reduced, to reduce overheads of a processor and improve image processing efficiency.

Image processing method and computer system

A request is sent from a new virtual function (VF) to a physical function for requesting the initialization of the new VF. The controlling physical function and the new VF establish a two-way communication channel that to start and end the VF's exclusive accesses to registers in a configuration space. The physical function uses a timing control to monitor that exclusive register access by the new VF is completed within a predetermined time period. The new VF is only granted a predetermined time period of exclusive access to complete its initialization process. If the exclusive access period is timed out, the controlling physical function can terminate the VF to prevent GPU stalls.
