LKT - Magisk 🏁

legendary.kernel.tweaks

LKT can identify your device hardware and optimize your kernel settigns for maximum power efficiency without performance loss

Why LKT ?

LKT is a cumilation of different strategies that target certain kernel settings.

What makes this special and stand out from the crowd is being universal and device specific at the same time. And it's also BS free. Using simple functions LKT detects the hardware of your device then it applies the corresponding changes. It does support all mainstream platforms including Snapdragon, Kirin, MediaTek etc. covering hundreds of devices.

Features

LKT aims to achieve the balance between power consumption and performance. Compared to tuning the parameters manually, LKT adopts Project WIPE excellent open source parameters for almost all mainstream SOCs that are generated via machine learning (A.I) 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 parameters, Virtual Memory, GPU, I/O scheduler, TCP and Doze rules to unify the rest of the kernel parameters for a more consistent experience.
