[KERNEL][CM][KK] Guru

ekerazha · Jun 15, 2014

Announcement: On 10 June 2015 I discontinued the project as my Nexus S is broken and I don't own it anymore

Take the latest CyanogenMod boot files ("device" and "kernel"), add cherry picked mods and build it following the CM guidelines. This is Guru.

This is NOT: A bloated kernel with dozens of randomly picked mods and then compiled with an exotic toolchain.

CyanogenMod-only
Based on CM 11 M10

CyanogenMod 11.0 M10 "kernel"

Nice performance profile.. This tests/feels faster than stock CM.. i/o tested a little lower compared to other KitKat compatible kernels, on par with CM... I will check out battery life...

Yes, there are no changes to I/O schedulers etc. it's the same as the stock CM 11 M7 kernel.

There have been some minor changes to the kernel since CM 11.0 M7 has been released (see June commits: https://github.com/CyanogenMod/android_kernel_samsung_crespo/commits/cm-11.0) and I just tested the compiled build on CM 11.0 M7, however I think it should work fine. Before you try to flash it on a 4.4.3 nightly, do a full backup from CWM.

Yes, MTP support and the "bigmem" patch are the main reasons for which I started this project. I could use kernels like Devil or Marmite (for Nexus S), but they are discontinued projects and they are not in sync with the latest CyanogenMod commits. I just wanted a clean and updated CM kernel with the features I missed.
