LKT is an advanced governor and kernel tweaks collection that aims to greatly enhance power efficiency and performance.
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.
Using simple functions LKT detects the hardware of your device then it applies the corresponding changes.
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. schedutil does not provide a wide range of tuning parameters but there are some workarounds.
In Snapdragon 835 for example on non performance profile, LKT slightly locks the maximum clock speed of big cores accordingly because big clusters power efficiency dramatically decreases above 2 Ghz, as a trade of losing 15% performance, improving power consumption by 40% or more is a much better deal.
