Features

LKT aims to achieve a fair balance between power consumption and performance. Instead to tuning the parameters manually, LKT adopts Project WIPE open source interactive parameters for all mainstream SOCs that are generated via machine learning AI and can adapt to multiple styles of workload sequences. This idea is similar to EAS, which takes into account both performance and power consumption costs through power consumption models and workload sequence. But obviously, EAS has a much lower response time and replaces tuning with decision logic.

In addition, it also includes other parameter tuning, such as HMP scheduler parameters, virtual Memory, GPU, I/O scheduler to unify the rest of the kernel parameters for a more consistent experience.

LKT also supports schedutil and schedutil based governos in EAS devices like the Pixel 2/3.

Requirements

• Magisk or init.d support if not using magisk
• Busybox (Needed for terminal commands).
