[G 2014 Android Development] BryanByteZ:
READ ALL BEFORE ANYTHING!

ATTENTION

/*
I'm not (yet) a developer , I'm taking effort to put more choices of kernel for our great community.
This kernel is tweaked for best balance possible, if you want a feature quote me and i will see what i can do,
I will build this kernel when possible on my free time and because of it is a nightly and I will use this thread as a worklog too.
Thank you for using this kernel.

* you point the finger at me for messing up your device, I will laugh at you.

Adapt, improve and evolve!​

Info:

Guys I created this kernel to Moto G 2013 (Falcon/Peregrine) and Moto G 2014 (Titan/Thea) in other words MSM8226 Motorola SoC baseds to learn, adapt some "unstable and unsafe" things as well to give a new life to my device, the plan is to support all Android versions avaliable for our device, I plan to do a better kernel with time and help of the comunity. This kernel is a nightly I will do it when I have a freetime or LineageOS update their sources or I add new features, it aims to be a rich feature kernel and a "perfection balance" between battery life and performance, this can be a UNSTABLE kernel, my routine will be build,upload and test, so stay tuned! I am open to suggestions. This is a kernel that don't work out-of-the-box the objetive of this kernel is give power to the user.

This kernel DO NOT WORK WITH STOCK MOTOROLA/GOOGLE PLAY EDITION ROM or IDCRISIS or AOSPARADOX.

How to install

If you're on other kernel please at least DIRTY FLASH you ROM, thanks.

The kernel:

By recovery:

Using TWRP (Please use the latest one)

1. Put the zip at /sdcard > Reboot to recovery > Install > Chose the kernel zip > Confirm to flash > (optional) Wipe caches > Reboot.

or

By app:

2. Flash it using Flashify or similar app from Playstore.

The kernel scripts backup your current boot.img so if you want to restore just use Flashify or TWRP.

The Bootlogo:

Using TWRP (Please use the latest one)

1. Reboot to recovery > Install > Chose the bootlogo zip > Confirm to flash > Reboot and enjoy.

2. Flash it using Flashify or similar app from Playstore.

3. Extract the zip and on mfastboot (or just fastboot) enter this command: fastboot flash logo logo.bin

Recommendations/Tweaking

Gov Tuner a mod to tune govs based on profiles for better battery life, better performance, or a balance., I have added a lot of sound patchs but A.R.I.S.E. will blow your mind! so if you want a better sound on your Moto G I suggest you A.R.I.S.E the best one in my opinion or just Viper+Dolby. And the best of the best tweaks app LSpeed just download and select a profile from main screen and fell it! or tune it by yourself!

To tweak use Kernel Adiutor from Playstore (or XDA Link), the Kernel Adiutor-Mod (fork with more experimental features) at XDA or Synapse You will need this zip and download Synapse app from Playstore.

Info about tweaking kernel The best guide to it!

Better RAM management for FALCON/PEREGRINE/TITAN/THEA thanks to @Pupet_Master

-Download "Kernel Auditor" from the "Play Store" and open it

-Once inside, Swipe from left to right to show the side menu.

-Tap on "Low Memory Killer"

-Change to these custom settings:

Foreground Applications: 29mb
Visible applications: 61mb
Secondary Server: 157mb
Hidden Applications 227mb
Content Providers: 87mb
Empty Applications 191mb

-Swipe from left to right again and tap at the option "Virtual Memory"

-Change those settings from there:

dirty_ratio: 20
dirty_background_ratio: 5
dirty_expire_centisecs: 100
dirty_writeback_centisecs: 300
min_free_kbytes: 4096
oom_kill_allocating_task: 1
overcommit_ratio: 100
swappiness: 100
vsf_cache_pressure: 53
laptop_mode: 0
extra_free_kbytes: 24576
Z-RAM Disksize: 470mb

-Swipe from left to right again and tap at the "Profile" section

-Click at the "+" button and save the current settings on a new profile

-Holdon the new profile and choose the option "apply on boot"[/QUOTE]

This kernel does not ships with a default config, so here it is how to config (an example) a profile for battery/balance/performance:

Battery

On CPU
CPU Gov - Interactive
Max freq. - 1190Mhz or 1094Mhz
Multicore power save - Aggressive
Alucard Hotplug - ON
On GPU
GPU max freq. - 450Mhz or 320Mhz (if dont play use 320Mhz)
GPU Gov - simple_ondemand or msm_adreno_tz with tweaked adreno idler
On I/O Scheduler
Scheduler - ROW or SIO

-

Balance

On CPU
CPU Gov - Interactive
Max freq. - 1190Mhz
Multicore power save - Enabled
AutoSMP - ON
On GPU
GPU max freq. - 450Mhz
GPU Gov - msm-adreno-tz
On I/O Scheduler
Scheduler - ROW or ZEN

-

Performance

On CPU
CPU Gov - Interactive

Multicore power save - Disabled
AutoSMP - ON

Note about some features

Display types WORKING with DT2W/S2S/S2W:

mdss_dsi_mot_inx_720p_video_v0 (TITAN/THEA)

mdss_dsi_mot_cmi_720p_video_v2 (FALCON/PEREGRINE)

Display types NOT WORKING with DT2W/S2S/S2W:

mdss_dsi_mot_jdi_720p_video_v1 (TITAN/THEA)

mdss_dsi_mot_jdi_720p_video_v0 (TITAN/THEA)

mdss_dsi_mot_lgd_720p_video_v0 (FALCON/PEREGRINE)

If you don't have a working DT2W/S2S/S2W or don't like it you can disable it and/or use AcDisplay app or Anbient Display of your ROM instead.

To check which display type you have by going into terminal and type:

su

cat /proc/cmdline

How to git and build

Setting up and building

Basics of GIT

- How to build my kernel:

export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
make mrproper (cleans config files)
make clean (cleans already builded files)
make falcon_defconfig (or you device_defconfig)
make menuconfig (if you want to tweak the config)
make (I use this too -o2 -j4 CONFIG_DEBUG_SECTION_MISMATCH=y CONFIG_NO_ERROR_ON_MISMATCH=y)

How to cherry pick commits

Basically to cherry pick a commit you have to have it source and branch, this is a simple how to do it

First of all you need to set your upstream since it is a fork of CM/LOS or STOCK source:

git remote add upstream linkingithub.git

For example

git remote add upstream https://github.com/CyanogenMod/android_kernel_motorola_msm8226.git

so if you want to cherry pick a commit from me

git remote add bryanbytez mysourcelink.git

and after that you need to have my source locally but stay calm this wont mess you source

git fetch -all

To merge upstream changes (From CM/LOS or Motorola)

git merge upstream/cm-13.0

This will merge upstream cm branch cm-13.0 in your source code.

Misc help:

http://xdaforums.com/showthread.php?t=2319018 (about boot.img, ramdisk and others)

https://stackoverflow.com/questions/2816715/branch-from-a-previous-commit-using-git (Unlike me you can just revert or create another branch based on the commit and not delete the whole source code :p)

https://stackoverflow.com/questions/4410091/github-import-upstream-branch-into-fork (Import a upstream branch on your fork)

And to revert a git: git revert sha1, example git revert eab5c8fef098548f0f00085196bbf40f41bf8ba1
