System scheduling optimization
Focusing on the user interaction experience, the solution breaks from the traditional completely fair scheduling mechanism of the Linux kernel and is centered around reducing the scheduling latency of UX tasks, improving the CPU bandwidth of UX tasks, intelligently detecting changes in the user's scenario and prioritizing the scheduling of tasks related to user perception, including display, network, memory and I/O. The scheduling algorithm is more refined and covers more scenarios, enabling more stable and smooth system operation.
UX scheduler
Bypasses the completely fair scheduler and prioritizes scheduling of UX tasks.
How it works
The completely fair scheduler is bypassed and a new UX scheduler and UX run queue are created. When the scheduler picks the next run task from the run queue, it is no longer based on the traditional
Vruntime, but on the UX run queue tasks, which improves the user interaction experience.
User perception
Smart detection of user scenario changes ensures improved frame rates and stabilized frames as well as reduced lag in all scenarios, especially heavy load scenarios such as gaming, multitasking and video streaming.
