Goals and their priorities
- Stability #1
- Battery life #2
- Speed #3
- Extra features #4
- Compatible with GLaDOS Control / Franco Updater App / Trinity Toolbox #4
Donations will soledly be used to buy the applications above mentioned or to share it with the developers I used their work from, so I can test compatability more often.
Everyone can make changes to this kernel. The only thing I will require from you is a SSH key as described in the help from github. This way everyone can contribute to this kernel. Extreme changes to the kernel must be approved by me or someone else I assigned to help me lead this project.

Developers list
- Jonas Hendrickx - djjonastybe
Features (what you see and experience) (also future features listed)
- Compiled with latest Linaro Toolchain
- 3.0.41
- CPU: enabled 1500MHz
- GPU: enabled 384MHz
- Fixed several bugs present in the stock kernel
- Custom Voltage
- C4 State (Cores can be turned off) + OSWR
- Customized compiler flags
- Color Control (Ezekeel)
- Vibration Control (Ezekeel)
- Sound Control (Ezekeel)
- Enhanced undervolting MPU/IVA/CORE
- No crappy workaround patches so we have a clean kernel.
Want more features? Want to see something removed? Want to see something changed? Please suggest. I don't eat you alive.
Coming soon
- Improved GPU Scaling 128/256/384MHz (Improved battery)
- Tweaked DRAM timings
- Requested: Trinity color palette source code
- Requested: Live OC (I don't like some aspects of Ezekeel's implementation. I believe some things can be done much shorter and much more efficient.)
This kernel focuses on changing bus speeds, removing useless code, and adding only useful things to the kernel.
Tweaking has been done carefully.
https://github.com/jonashendrickx/MAGURO-JB/tree/android-omap-tuna-3.0-jb-pre1
We do not want to exceed the limitations on our device. Don't ask for 2.0ghz overclocks or 512mhz GPU. It's still a phone and it will always be one. I will add it when I am ready.
Want to contribute to Speedy Kernel? Read the requirements.
Requirements:
- Knowledge of github
- Generate a SSH key and send me the public key: eg id_rsa.pub.
- Know that I can revert your code and accept this. It's still my kernel.
Depending on how much people want to work together on this kernel I might start a kernel which is open for anyone to edit. Only I will setup the repository.
First!
You here too!

Hahaha nice one!, i also sold my NS, and im getting my GN sunday , see ya ssoon
I am wondering how I can activate SLUB. I don't know what Android is using for stock. But apparently some devs use SLQB. I read SLUB is little faster when using Google Search.
I am going to make a first upload.
More features are coming ofcourse.
Uploaded. Please flash with fastboot. I am not going to make update.zip files. I find it faster and more efficient to do it this way. I might look into making update.zip files later
Released. Update.zip also.
Currently I have only enabled the green features. More is coming.
Do you at least know what is SLQB and SLUB ?

Looks interesting, I'm installing it now.
Fast Charge would be a nice addition though.
Good to see a Belgian developer join the scene!
I don't know. I think you can turn off FSYNC with GLaDOS Application. I am not sure. I am still new to the Galaxy Nexus mods.
I will take a look into enabling PGM app support if I can disable it for those who don't use it.
Rcbrt thank you! I will try again github tomorrow night or maybe upload everything sunday.

After building a CM9 kernel with some added features as part of my CM9-UNOFFICIAL-building, I decided to make a separate kernel topic: Mackay Kernel.
This kernel is based on stock CM9-kernel by pawitp.
Today's release will be the final ICS release! From today on I will start working on a JB kernel. First release may take a few weeks.
Because it is a final release, there will be 4 flavours:
-regular
-XLmem (396MB RAM, no 720p recording, 720p playback works)
-VC (Voodoo color)
-VC+XLmem
If you like a CM9 with the Mackay Kernel included, there is also MackayROM, which is an adapted CM9:
http://forum.xda-developers.com/showthread.php?p=28149230
Changelog:
12 August 2012 - ICS_Final
Changelog
Additions since previous stable version:
s5pc110_battery: fix charging display for car dock
fix freeze when max frequncy is set to 800 MHz
fixed charging-autostart bug, now the device stays off, and powers on properly (thanks DerTeufel)
Updated to linux version 3.0.39
General features:
Build using the July Linaro toolchain
O3 optimization
Updated to linux kernel version 3.0.39
Mackay kernel bootsplash
Based on a single initramfs & using bootloop detection to prevent bootloops
Mackay recovery (based on CWM recovery v6.0.1.1)
Governors added:
SmartassV2 (default)
Wheatley
Optimized ondemand/conservative parameters
Schedulers:
SIO (default)
Added functionality:
Bigmem (384MB; XLmem of 396 available as well)
Adaptable vibration intensity (by setting /sys/class/timed_output/duty)
Improved SD-card read/write speed under windows
Call volume hack (using Settings>Advanced to set volumes)
Reduced battery polling interval

Goal is to have a basic kernel with some add-ons. There are some full-blown kernels for CM9 like semaphore/devil which give a lot of extras. But I like to keep it closer to stock (with no need for additional kernel apps), but still add a few extras.
Just flashed, working great. I guess we had a hole with a simple kernel after mialwe jumped to gs3, now it's full.
Can you compile with o3?

Hi Kasper,
Have been using your CM7 kang builds and they always worked smooth. I am really happy to see you making a "close to stock kernel" which i guess lot of people here would appreciate.
Best of luck n 3Cheers

@kasper_h Thx for the kernel, its super slick! I just miss one thing: BLN, can you add them in next version?

No plans for BLN. BLN is one of those features which requires a special app. I use the regular led notification myself which is controlled through CM9-settings. Less powerful, but also no additional memory footprint from an additional app.
With regard to -O3 flags, I will definitely look into that.
I just recoded my OC patch, used midnight kernel as a template. I hope to finish that part of the project later today. After that, I will look into compiler flags.

This is indeed the patch I looked at to implement OC Adapting it to include an additional 1400MHz OC step.
I just added a testversion of the Mackay kernel. It includes OC (only 1200MHz for the time being). This is quite stable for me, but not perfect yet (my phone is very bad at OC, so I can not really test this very well).
Removed the OCtest kernel as it is buggy for me: it just stops working when screen is turned of for some time. Need some more time for trying/testing etc.
I uploaded a kernel I've wanted to start working on for several months- been kinda slow figuring out git & compiling
download is on my GitHub page here
I've just added several small commits building on mrg666's kernel (if I should start a new thread I will but right now I don't know where I'll take it- if anywhere. Part of it was just to see if I could do it.
It's got a few commits from drewwalton's hydrokernel, super kernel dev Francisco Franco's P500 kernel... maybe more to come as I look around hunting for other little things. I'm not a developer so I'm really not prepared to do debug 50 file commits.
compiled with latest Linaro toolchain.
Thanks to all of the people everyone thanks- especially mrg666 for answering so many of my trivial questions.
I've been running it for a couple of days with no reboots or anything. If anyone wants to get in on the action there are some dev teams like those who build the Italian Nexus Kernel. It'd be cool to go some direction like that- everyone throwing great things at it.
Installed last night, seems to be maybe possibly a little zippier.

Yeah. I have a few new changes I did last night from someone who seemed to be hitting some good stuff.
The changelog is here, btw: https://github.com/jawz101/android_kernel_thunderc/commits/VM670-IHO
backported a lot of code from 3.x kernels regarding cpuidle, scheduler tweaks and even updates to the Android low mem killer. I'll post a zip to it a little later on today. I put it on my phone only last night before going to bed. As an IT guy I can tell you that people don't notice 'faster' as much as they notice 'slower'. Me included.
All I know is it compiled so I pushed it to my phone and it didn't blow up :highfive:.

Maybe. If I'm not mistaken drewwalton did the reverse by just adding a commit that swaps some key mappings to get his hydrokernel working on the optimus v. I'll try a bit later but I can't promise simply because I'm not great at this.

Just an update. Now that I've taken the leap and done some work I'm mainly doing some reading about things.
Also checking out other repos out there to see what others are doing. One that is intriguing right now is the candied kernel. Check out my watched repos on my git account. It's a p500 kernel based on the official cyanogenmod kernel for that phone.
Well if you can somehow improve the (assumingly) abysmal 2D acceleration I'll be on board. And by that I mean its really insanely choppy to scroll without having 16bpp transparency.
Any input on what you're experiencing? Is it games? Are they using opengl? This is where I'd fall short not knowing where to go with that

Oh its just typical of the CM7 ROMs. I nitpick yes, but if your wizardry is that good why not ask for it?
Oh I'm no wizard. mrg666 does a lot more than I do. I just add one-liner changes I get from other people's ROM's for other phones.
I have no attention span and just hit discard if a commit has conflicts with the existing code. I still look for anything related to performance, battery life... or just sounds smart.
I wish I understood the hardware enough to know where get and how to incorporate newer drivers. I can't really see a few years of linux kernel development since 2.6 would make 3.x kernels have a noticeable difference in function unless there was some glaring flaw in how certain things are handled.
The only room for improvement I could see to be noticeable would be to find newer drivers for key components and get them in the kernel. If LG used 4 year old drivers and there are ones available 6 months ago there could potentially be some big benefits in video, cpu and networking support.
Since this guy's p500 kernel is an actual cyanogenmod supported kernel there's surely some stuff to be found there
It's cool. Thanks for the reply.
I remember you wanting to get started on this...
good work.

Thanks guys. I've been flying under the radar. Probably because I'm not posting on androidcentral.
Uploaded a couple new builds just now. Mainly changing to o3 compiler optimizations instead of o2 and disabling compiling to optimize for size.
It made the zImage come out at 3.5MB instead of 3.0MB but who cares? I mean, I'd rather have whatever other optimizations there could be versus half a MB of kernel size. I'm also trying to fall in line with Linaro's recommendations.
Anyway, they're up here https://github.com/jawz101/android_kernel_thunderc/downloads
The commit I'm most suspicious about is the 'new battery driver one' because I just slapped it in there.
remember to backup, clear cache & dalvik cache before each kernel update.
That candied kernel is crazy full of stuff - I wish we had cyanogenmod support like they got.
things look pretty good on those last to updates. I threw in a few more commits yesterday that I haven't pushed up remotely that I'm still testing on my phone. mainly adjusting some more gcc build flags & pulling in some cpufreq update from Code Aurora. My phone seemed laggy last night after that cpufreq update so I'm still holding off throwing it out there to see if it was just a coincidence from other things I had open at the time or what.
someone mentioned I hadn't been adjusting the build date in the about section in settings. I'll start doing that again in the next release. I wish it was dynamic every time I compile because I don't like that you have to add a new date each time but oh well.
btw, if anyone wants to get in on the action I'd be glad to help with getting you up and running on toying around with kernel stuff. I'm still a newb but I think the whole idea of kernel work is more interesting and beneficial than custom ROMs.
Right now I'm using Xubuntu 12.04 64 bit dual booting my windows box via Wubi, SmartGit to do the cherry pickin', latest Linaro toolchain for compilation and a cheat sheet of commands to run the compiles.
I also enabled something called ccache on my kernel to speed up build times quite a bit. I really don't know why many kernel devs out there don't use it unless they think it could introduce some reliability issues in compilation but I haven't noticed any issues.
I spent a lot of time evaluating git management programs initially to find something I liked & ended up settling on SmartGit but still use some of the other gui's for a different look or certain functionalities.

the cheat sheet is just the commands to run the make of the kernel once I've make changes. I'd say getting everything else ready for compiling the kernel was the slowest step for me. If you have any questions for that let me know. I'd try hunting around on the interweb 1st and if it's a bunch of questions make another thread and we can break down the questions as you have them.
been using the 0808 since you posted and i have to say its very zippy... i keep cpu spy to track usage... nice work... looking forward to future updates... thanks...
Kernel+ for AOSP 4.2.2 ROMs
This is a kernel that I have been compiling and using on my own device for a while, and I want to share this with the community. I enjoy the CM10.1 stock kernel, but I want to keep up to date with the newest Linux version and CodeAuroraForum source. I also want the most optimized experience possible, along with a few extra features. Kernel+ is always built with the latest Linux kernel and Qualcomm CAF sources to provide a fast, stable, and bleeding edge experience. The source can be found on my GitHub here Enjoy .
What is this?
This is a kernel based off of CyanogenMod's 'cm-10.1' branch of the Galaxy S III kernel.
Kernel+ is built with the goals in mind:
To always be up to date with the latest source from CodeAuroraForum and Kernel.org
To optimize as much as possible for the smoothest user experience
To base closely off of the CM10.1 kernel for optimal stability, not features
To provide a fast, stable, and bleeding edge experience for users
Features
Linux 3.4.54
always up to date with the latest source straight from Qualcomm's CodeAuroraForum
latest Linaro 4.7 toolchain compiled
CPU frequency from 384Mhz - 1.5Ghz
FauxSound App support
FRandom built-in
GPU overclocked to 480 Mhz default
custom voltage control
excellent battery life
optimized and stable
small kernel size
more coming soon...

Instructions for Installing
1. Download the kernel.
2. Copy it to your phone.
3. Flash with TWRP or CWM.
Note: Kernel+ is packaged with invisiblek's AnyKernel, meaning that it will unpack your current ramdisk and repack it with this kernel during the flashing process. This means that it will be compatible with any AOSP 4.2.2 ROM, even if they have different ramdisks. Also, please make sure that you are currently running a stock AOSP kernel (CM10.1, AOKP, SlimBean, etc) before flashing Kernel+ so that your ramdisk will be compatible.

By default, the GPU is allowed an extra 480 Mhz freq step, whereas stock only allowed up to 400 Mhz. If you feel that you do not need the extra GPU 3D power, then you can disable it by adding the line:

echo 1 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_pwrlevel
to the file /system/etc/init.d/98kernelplus. Then reboot.
How do I adjust the voltages?
You can control the CPU freq voltages by using an app such as Trickster, System Tuner, SetCPU, etc.
What is frandom? How do I enable it?
Frandom is basically a more efficient random generator. It can be used in place of /dev/urandom and is 10 - 50 times faster. Using frandom will use very little of the kernel's Entropy pool, which in turn will provide better performance and smoothness. Frandom is already built-in to the kernel and enabled via an init.d script. No need to manually enable it.

Nice! I've been wanting to flash some AOSP, will give this a try...

Hmmm....interesting I guess I will give this a 72hr run on vanilla RB nightly then report back vs stock kernel...which btw I'm running.

OK
You got my attention, im a try this out
Tried two downloads, failed the flash each time. It just says flash failed, right after "Updating Partitions...."
Are you guys phone FC'ing after this kernel? I'm trying to figure out if its this or the free next launcher 3d offer they was giving out yesterday that made my calls go bonkers.

I may be wrong but I don't think a kernel will cause force closing issues. Also, Ive been running the next 3d launcher with slimbean6 and its very smooth. Try wiping dalvik/cache then reboot and if it's still occurring then clear data under Settings->Apps for whicher app is force closing.

Anyone else have this problem? Try reflashing your ROM/kernel, boot up, and then boot into recovery and flash this kernel again.

That's why I was a little confused. Everything was fine on the latest vanilla RB until either this kernel or next 3d launcher. Thanks. I will get it sorted out!

This morning I pushed a few commits to bring it up to date with the latest cm10.1 kernel and adjusted the MDP bandwidth values...I have yet to test them though...

Can't speak on the battery life yet since I switched ROM back to cm rc5 since the call fc issue I had with RB. However, I'm getting some flickering but it could be rc5 issue. Other than that this kernel seem so damn smooth battery life seem like its good too but a little early to judge. Nice new toy op!:beer:

I am currently testing the commits I pushed this morning, and so far I haven't experienced anymore flickering with the new MDP bandwidth values. :good:
I just need to add a few things and an update will be coming soon!
But for now, if the flickering really gets in the way, check disable hw overlays in developer settings. But just FYI if you check that option you are basically disabling project butter, and your experience will not be as smooth.

If anyone else is not experiencing flickering than I'm guessing its RC5 (CM). I will look into it and do more testing to see what might be the culprit. Thanks!
Sent from my SPH-L710 using Tapatalk 2
I take that back...even with the new commits and bandwidth values, I still get flicker, although it seems to be less often. I still have to debug more and see where it is coming from.
Stay tuned...

I just finished tweaking the MDP bandwidth parameters, and I think I have found the sweet spot. There is no more flickering at all. Just a few more things I need to add and it will he ready for a new release, probably tomorrow.

No sir,
More.. is usually in all of my feature lists because I always seem to forget something
Does it feature color control to change values in gamma and rgb settings?
First, thanks for sharing the kernel, i like it to play with different kernel.
One question,
Gamma Control a planned feature in the future ?

No. this is a v1 so many of what will be added is not currently there.
Also, the goal of this kernel is to stay as close to stock as possible while enhancing the performance, battery-life, and usability of the device.
Color and sound may or may not be included in future iterations
In download [emoji3]
Favorite Note 2 kernel was Jedi. Nice to see its way to Hammerhead!

Do core (two or three) in offline?
Ok will try it now
Edit: kernel runs... Looking for good settings. Using ondemand and deadline for now.
One thing I miss.... A sound mod... Sound is to low... And the quality is not the best... Are there alternatives?

I'm pretty sure the dev wants us to use stock settings. Otherwise he wouldn't have made them default
For sound use viper mod. I don't see any kernel changes necessary for this.
Runs ok. Oc to 2.5. Uv would be nice
Slimlat 5.0.2

This. Glad to see him around here. Didn't think he would have a Nexus 5. Welcome to the Nexus 5, hope you're here to stay man.
Edit : Reporting that Jedi kernel does in fact run on 5.0.2 stable so far.
leanKernel is not for everyone.
My philosophy is to keep the kernel footprint as small as possible by trimming as much fat as possible, and at the same time keeping it stable, power efficient, and fast. leanKernel is designed to be a drop in replacement for stock kernel, and so it tries not to deviate too far from stock.
You will find that it's lacking some of the bells and whistles of other custom kernels, so if you like features you came to the wrong thread.
Here's a longer post on what leanKernel is about.
DOWNLOAD (flash in recovery)
download and CHANGELOG (github)
renderserver download
PREREQUISITE
Unlocked bootloader, custom recovery installed, rooted (if lkconfig is needed)
FEATURES
updated to latest 3.10 Linux
interactiveX - screen_off_maxfreq support (governor name was not changed from interactive)
compile optimized for cortex-a57/a53 and other gcc 4.9 optimizations. (toolchain: sabermod)
various performance/stability optimizations
fat trimmed by removing unnecessary components/features
force encryption turned off (changed to encryptable), /system verification disabled
lkconfig (lk) script for customizing leankernel (see below)
kcal color control (thanks to @savoca)
random generation optimization including e/frandom support, no need to tweak entropy
cherry-picked commits from CAF repo
wakelock control (wlan_rx)
display cpu voltages via sysfs (via compatible apps)
replaced deadline i/o scheduler with sioplus
a53/a57 overclock frequences (enable via lkconfig)
more to come!
lkconfig
Open terminal app, disable "Verify PATH entries" in setting, become superuser, then type "lkconfig" (or "lk") without quotes
Code:
[email protected]:/ $ su
[email protected]:/ # lk
leanKernel configurator
---
0) display current settings
1) wake gesture control
2) wakelock control
3) rgb/picture control
4) interactiveX control
5) cpu overclock control
21) check top 10 wake locks (ie. wakeup sources)

Where is interactiveX?
It's there - it's called interactive. Screen off max frequency can be tuned via lkconfig, KA, etc (by default it's set to 1.5ghz). I finally decided that changing the name of the governor was lame.
cool nice to see you here:good:
I've been running 0.2 for a few days now with no issues to report and decent battery life. Looks like you're off to a great start.
Welcome to the Nexus 6p club! Good to see you here.
Great to see you here imoseyon.
Eagerly awaiting source code release, or any ideas you have on how to govern this 810 for battery and responsiveness.
Also, did you see the reddit r/nexus6p posts on the Google kernel commit that introduced washed-out blacks when hardware decoding video?

Thanks for that - I just read it. If there's anyone that can reproduce this issue, I'd be happy to put up a test build with either the offending commit reverted or fixed (if I have time to analyze the code).
Yeah, I can easily reproduce.
