[KERNEL][KITKAT] [LINARO -O3] MajesticKERNEL 1.0.9 - 4/3/14

blackburn29 · Mar 19, 2014

Welcome to MajesticKERNEL by Blackburn29

This is my first time developing a kernel for a mobile device. As a power user myself, I aim to give the best battery life possible and give users the ability to tweak the kernel to their heart's desire. Not to mention, some phones are picky! So it might take a little tweaking to find the sweet spot! (I personally use Trickster Mod to adjust my kernel settings!)

This kernel is compiled using the LATEST linaro toolchain with -O3 optimizations and device specific tunables.

Here is a screenshot of my battery stats on MK_1.0.4:
Battery drain of ~2%/hr

A list of just a FEW of the available features are:

Slight overclocking up to 1.62GHz
Underclocking to 54MHz
Voltage Control
Built-In Hotplugging interface (Used over MP-Decision)
9 different schedulers to choose from
13 optimized governors to choose from
Ability to disable cores via a sysfs interface
Simple GPU Governor
VFP Optimizations
GPU Overclock to 480MHz
Always UPSTREAM of CM
Fastcharge
Latest Touchscreen Firmware
Cooled OLED Colors
FauxSound
MSM_SLEEPER interface (Max screen off freq control)
Fading LED from DecimalMan
Hardware Key Fade animations from DecimalMan
Increase clock speed to max freq at boot to increase boot times

List of CPU Governors

Badass
PegasusQ
SmartassH3
SmartassV2
IntelliActive

Wheatley

Ondemand

Powersave
Intellidemand v5.0

List of Schedulers

noop
deadline
bfq v6

cfq
fiops
zen
fifo
sio

List of CONFIRMED ROM compatibillity

CM11
SlimKat
OmniROM
OSE
Beanstalk
Vanir
AICP

How to Flash:

Boot into recovery
Flash the "MajesticKernelvX.X.X.zip" file
Wipe Cache/Dalvik
Fix Permissions
Reboot and Enjoy!

Note: I HIGHLY recommend doing 2 FULL charge cycles after a kernel flash when you wipe the caches. (Ex: 100%-0% uninterrupted, 2 times. I usually run a benchmark for the last ~15% to drain it down to 0.) This will allow android to generate accurate battery statistics for your device. (Google Glass recommends this on the official forums, and I notice a fairly large difference on both my Glass and my phone when doing it)

I'd like to give many thanks to the following people:

Anyone else I may have forgotten that has contributed to this device's development!

This looks great, but I just flashed it over the latest Carbon nightly and I get stuck at the kernel boot logo. I had to do a battery pull and flash another kernel in order to boot again.

Well unfortunately 1.0.5 will not flash for me. Status 7. Going to try and redownload and flash again.

As for 1.0.4, it pegged my minimum at 900 and i couldn't lower it. tried on multple ROMS.

It flashed for me, BUT I get FC's on ANY app that is Google dependent. Email also FC's. This kernel is a no-go for now. I appreciate the efforts from the dev.

I would suggest switching the BFQ you're using. It's not built for our kernel version! As well as a few other things. I'll PM you some suggestions.

Ferenczy68 · Mar 21, 2014

Is this kernel for all D2 variants or just the ATT family?

And this is how XDA should be, all of the time :good::highfive:

The kernel actually has BFQ v5r1... Sorry for the misunderstanding in the commits on git! But also thanks Pwn for the help, I really appreciate it

All d2 variants! But wait for 1.0.6 that will be out in a few minutes

I had this issue too. He's using an older update binary. Philz cwm had an option to allow older binaries.

Wheeeeeeew!

blackburn29 · Mar 21, 2014

I will look into updating this. Thanks. I was unaware since it flashes fine in TWRP
