OpenKylin openKylin today officially launched version 0.95, built on Linux 5.15 kernel, default with a new generation of UKUI 4.0 desktop environment, deeply optimized tablet mode, upgraded system interoperability features, support device screen casting, remote control, fast transfer.
The openKylin 0.9.5 release also adds a new “hierarchical freeze” mechanism to achieve hierarchical control of system applications, and integrates VirtIO-GPU hardware video acceleration mechanism to significantly improve system 3D performance and provide smooth graphics display effects.
In addition, openKylin 0.9.5 unlocks the ARM architecture, adapts to Raspberry Pi and COOL Pi development boards, and integrates a new software store by default, fixes 260+ known defects of the system, including the inconsistency between the system side and cell phone side of the multi-terminal collaboration can not be connected, and some functions of the sound module can not be used normally after upgrading from version 0.7 to 0.9. The system interaction experience and stability are further improved.
UKUI 4.0 desktop environment
The new generation of UKUI 4.0 desktop environment supports one-key system theme switching, global gesture evocation in notification center, dynamic shortcut buttons, PC & tablet switching, etc. It also supports evocation/hiding dynamic effects, and deeply optimizes tablet mode, adding more features of tablet mode, such as gesture operation, touch, vertical display, etc.
“Grade Freezing” Mechanism
“Hierarchical freezing” is a set of application process life cycle management mechanism specially designed and developed by the openKylin community. By “grading” the applications in different states, “freezing” the user’s unoperated applications 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
To solve the problems of high CPU usage, video stuttering and frame drops when playing HD videos in virtual machines, the openKylin Community Virtualization SIG group has developed a pioneering hardware video codec acceleration mechanism for VirtIO-GPU with front and back-end architecture to significantly improve the experience in virtual machine scenarios.
Multi-architecture support
In addition to X86 architecture, this 0.9.5 release unlocks ARM architecture, officially adapts Raspberry Pi and Cool Pi development boards, and supports Raspberry Pi hardware and software development mode. At the same time, the RISC-V architecture Pinto Trailing Shadow 1520 development board has been adapted to meet the needs of users in multiple scenarios.
Software Store Newly Revamped
The new UI style of the software store has been revamped, with a more concise and beautiful interface, clearer application classification, and more convenient synchronization, as well as the addition of openKylin ID login support, improving the user’s visual experience and operating experience.
