[Sony Xperia ZL] airlessproject:
Introduction

The idea for creating this kernel came up around a year ago, during early LP custom ROM builds. I thought it would be a nice idea to fork the most advanced kernel at the time, EvoMix, developed by our renowned Olivier, Joe (SuperHanns) and Alex, and add to it the latest upstream 3.4 patches as well as mix its features with another good kernel, KMA.

After that experiment turned out not so bad, me and fellow xda user BrateloSlava got an idea to continue developing that mixed kernel with our own cherry-picks from the best kernels available for various devices, and use it in my builds of RR and later GZR Tesla ROM.

Now, one year later, I continued the development that BrateloSlava did on the kernel for the last months for my Tesla and Validus ROMs, and I thought it would be a nice idea to extend this kernel's availability to the users of all custom ROMs around at the moment.

So, here is Airless Kernel for Xperia ZL, compatible with all CM/AOSP based Marshmallow ROMs.

- Voltage regulation

Thermal management

- Simplified and efficient thermal driver

- Flexible ramp threshold temperature

GPU
