"Hierarchical freezing" is a set of application process life cycle management mechanism specially designed and developed by the openKylin community. By "grading" processing of applications in different states, "freezing" the user's unoperated application in a special way, thereby releasing the system Resources (such as CPU, disk I/O, memory, etc.), give priority to ensuring the resource allocation of the user's current operating application to improve user experience.

VirtIO-GPU hardware video acceleration mechanism

In order to solve the problems of high CPU usage and video frame drop when playing high-definition video in virtual machines, the OpenKylin community Virtualization SIG group pioneered a set of hardware video encoding and decoding acceleration mechanisms using front-end and back-end architectures for VirtIO-GPU. , greatly improving the user experience in the virtual machine scenario.
