Changelog
Version 1.0
* Initial release
Version 1.1
* Compile with Linaro 4.6 to fix instability.
@devs: This kernel package only updates the kernel binary and modules using the same technique as AnyKernel. This is all done with the included updatebootimg binary, which is a modified version of the standard mkbootimg.
Usage should be obvious if you look at the edify script. It can update only the kernel, only the ramdisk, or both (but if you're doing both, you can just write a new boot.img directly and be done with it).
Feel free to extract the package and use the tools to cook your own kernels.
Sweet. Trying it now
tmdcode, can you build a kernel for lu6200 from vs920 cm source? We have cm 10.1 rom for lu6200 which ported from p930. But kernel from ported rom is not good enough for daily use.
@tdmcode
Do you get warnings when compiling with Linaro toolchain?
I dunno if these warnings affect the stability though compiled successfully.
P930 kernel works but SU640 kernel stucked at LG logo.
Moreover, where to get "kernel" file from compiled kernel? Is it zImage?
Thanks

@lyfkevin:
Linaro warnings like this are normal:
unwinding may not work because EXIDX input section ... is not in EXIDX output section
The compiled kernel is arch/arm/boot/zImage. this is frequently renamed to "kernel".
The kernel I posted yesterday reboots when GPS turns on for P930 and VS920. Apparently it doesn't even boot on SU640. So I will be making a new one today.
For me it reboots when connected to BT headphones and making a call ...

Despite what you might think, I'm not really a governor/scheduler connoisseur. I just run the defaults. I do run at max freq though.

Well to tell the truth, I don't really believe in all of this scheduling/governor algorithms.

With a fully charged battery and after idling for 8 hours battery dropped to 90%.
GPS works and locks.
Bluetooth having issues like all other 4.2 based roms.
@tdmcode my device (P936) go in boot loop after install your kernel, what could be the reason?
I test it with CM10.1 & official AOKP
FYI: wind kernel is working fine after remove the under voltage setting

Wifi, calling, 3G, camera, video.
Would love to see stuff like BFS, interactive/smartass scheduler and more intermediate speeds at the low end (if possible).
Might just try to build one myself.

No the MAC address doesnt get altered like one the other kernels. Most of the others have been fixed and dont do that anymore.
Nice work, pershoot! Everything seems to work together nicely. Hopefully, this might help with the battery life with the addition of my screen off profile clocked at 245...

if you have setcpu set to on boot, flash back to stock, untick that option, then flash this kernel.
go up in 50/100 MHZ freqs and test at each spot. use ondemand cpu governor. tell me which freq(s) your device is having issues with.
thx.
Flashed over cm rc 2. Looks fine - glad this thing is finally getting undervolted. Cm kernel is not optimized enough.
However, this kernal has too many frquency sets. In setcpu most frequencies are at 0s total use tiime.

First is an O/C kernel that I built from the HTC source. This kernel is stable and with the right profiles setup in setCPU has given me very good battery life. I'm giving coolbho3000 credit here as his post in the G2 forums is what helped me to do this. I am also acknowledging gr8gorilla who helped me several times through this process. Second is a kernel built from the latest CM kernel zource from zinx. It has proven to be very stable (after tweaking the voltages).
Now for the boring part ... If you choose to flash this you do it at your own risk. I am in no way, shape, or form responsible if you flash this and your phone turns into a paperweight. Once again, flash this at your own risk.
There, now that that is out of the way we can get on to the good stuff.
Make sure you choose the right kernel. The stock kernel will break your CM install if you flash it.

I have packaged this into an update.zip format that you can flash through your custom recovery. Simply choose to install a zip from the sdcard and pick the update package to install it. It will install the wifi driver at the same time so you don't need to worry about that. Everything works with this kernel so far for me if you have any problems please post them and I'll see what I can do to fix them.
Remember that you hardware is not the same as your neighbor's so while he may be able to max the settings out and run stable your device may need to be set to a lower clock speed to run stable.
Source code for both kernels has been added to github. If you want to play around with them download source from here: https://github.com/grankin01
Happy Modding/Devving!
wow, thank you sir
I was just about to start testing kernels with Zinx's CM6 anyway. Looks like yours is first.
hmmm... could not run update.zip through clockworkmod. I was looking to extract the files and push them manually, however, I don't see a zImage file to push.
No luck with the miui rom. Cant get past the splash screen.

Not yet. It will work with the rom that you have installed right now though.
hey guys. im a noob to android. every other phone i have had has been winmo. i wanted to try this oc kernel because it seems easier to install than the gorilla one. however i ran into a problem when installing. i have a stock rom 2.2.1, perm rooted s=off, using clockwork recovery. i backed up my rom and flashed via rom manager. it then began to send me into a boot loop never getting past the first screen. just kept turning off and rebooting. soooooo i rebooted directly into clockwork and tried to do it from there and the same thing happened. so i restored my recovery and now everything is back to normal. can anyone point me in the right direction? i did notice that in clockwork it gave me two options to flash the kernel or to flash an update from the sd card. should i have flashed the update zip instead of the kernel or flash both.. sorry im a partial noob. i know how to use adb a lil and the emulator, this is the first thing i flashed on my phone and nearly had a heart attack from thinking i was bricked! any help is appreciated
Do you already have setCPU installed? Not everyone's phone will be able to reach the maximum speed without bootlooping or locking up. Just the nature of the beast. Try setting your speed down in setCPU (if you already have it installed) and turn set at boot off and then flashing and rebooting. Then you can test the speeds one by one to know what is working for you.
Edit: New kernel for CM and MIUI is nearly ready. 1.8Ghz with over 3200 on quadrant!!!

Only in the lower frequencies. The higher frequencies weren't stable running lower voltages.
Thanks OP. When you say the lower ranges, at which MHz did you not UV? Just curious. I am thinking of not OC'ing more than 1.4MHz and didnt know if I would get the UV benefit.

Presenting, my HD2 NAND Android kernel!
Summary
To provide, stable, fast and up to date kernels for our HD2s running either DFT or CWM nand android
Features
- 1190, 1190 Undervolt auto scaling versions available. listed is kernel MAX speed, it will scale to anything less depending on demand and ROM installed. Default max seepd is 998 without the use of an overclocking app
- Faster IO tweak taken from hastarins kernel tree
- Latest YAFFS driver
- Always built from latest source tree
- Very responsive kernel configuration
- Battery efficient
- Supports EXT 2 / 3 / 4, depending our your chosen ROM
- RMNET / PPP both supported, depending on your chosen ROM
- Bluetooth, WiFi, LED notifications all working correctly
- Smartass (default), Interactive and all standard CPU governors supported
- CIFS supported
- MAX defualt speed is 998, use setCPU or similar to overclock if you so wish
- cLK supported
- Automatic Extended Battery Support
Choosing your kernel
1190Mhz
This should work perfectly on nearly every HD2. It offers good speed at a slight cost to battery life. It will, depending on how your chosen ROM implements it, scale anywhere between 245-1190 Mhz depending on load
1190Mhz Undervolt
Same performance as 1190Mhz above, but with lower CPU voltage settings. It will work perfectly on most phones, but not all. If you experience FCs or random reboots then chose one of the aforementioned versions. This kernel offers significant battery life improvements if it works for you.
About the source and GPL compliance
The kernel is built direct from main GIT. You can access the commit logs and sources here on gitorious
The changes and modifications as mentioned in the changelog, and my build .config are all in my separate patch file, which you can download here
Download
All the kernels are supplied on one zip package. Contained within the package are the 2 kernel zImages and the associated modules. Chefs and advanced users will know what to do with these.

First! This is in a kleandroid 2.55?
yes....and no
its just been recompiled, and i added pure 998mhz for people who have phones that cant take the faster speeds!
Awesome! This is the best kernel, have been using it for like three days and it gives me the best battery life and performance. I loved it. I'll pack this one into cwm zip when I get home and flash it.
Edit: how much does battery life actually improve with the uv one? Now I'm torn between the uv and oc to 1.5ghz. Battery or performance?

Can anyone test this on sergio's coredroid 1.4 and post results? I would but dont have my computer for a couple days.

Please add 998Mhz kernel to next update CleanDroid!

you might get maybe possible 15% more battery time out of the UV kernel. in ideal circumstances in a perfect world of course
CWM
How to use that? :-(
Any zip to use on cwr?

Not yet, it is still underway.
I made some cwm zips, before going to sleep. I wasn't able to test them because it's late, but they should work. If g.lewarne wants to post them in the OP, i have no problem. Inside the zip, after you download, there are 4 more zips, one for 998, 1190, 1536(this one doesn't work for me) and 1190 UV. Just flash the one you like and enjoy!

Please give feedback, again I say, they should work but haven't tested them. I've made all his previous kernel versions cwm zip, and flashed them successfully.

Thank you!
1190Mhz Undervolt its working here.
1536 does not work for ne! Causes random reboot on boot. If you want to test it, do so, but i'm pretty sure it's a problem with the kernel, not with the zip, because the one g.lewarne uses on his rom had 1536 and caused random reboots too, cant be a coincidence . Also, youre welcome!
I flashed the 1190 to test, now off to flash the UV one!

It works, but not the 1536 one, or at least not for me.
Sent from my HD2 running Android on NAND
Might I just point out that in real world situations the 1190 kernels are just as fast. 1536 is really just a gimmick but some people want it so there you to. Myself, I run my own personal 1305
Sorry for spamming this thread, but I must ask, is uv dangerous? If so, what are some steps I have to follow to prevent my phone from getting fu'd? Like for example,i know that for the 1536, we shouldn't have it always o/c'd to the 1.5ghz.

Installed the UV Kernel on Coredroid v1.4 TMOUS ver its getting stuck at GO GO GO
Hi
I have been testing a new kernel I built. It is based on the CM kernel, and I have tweaked it with some of the voltage mods and OC settings from the wind kernel. For good measure I added a couple of governors in as well. Oh and i updated the kernel to 3.0.91
Changes
lulzactive governor and smartass2 added: there is a playstore app for tuning the lulzactive http://tegrak2x.blogspot.ca/2011/11/lulzactive-governor-v2.html
Update to linux 3.0.91
OC and voltage tweaks from wind kernel
Personal experience
lulzactive governer seems to work great for me.
My phone maxed out at 1782 MHZ, this has been very stable for me (at 1836MHZ my phone had random reboots).
Antutu benchmark 10,131 (With straight CM benchmarks was 9.376)
Installation: reboot into recovery install zip. To revert flash ROM.
NOTE THIS WILL ONLY WORK WITH A CM-11 ROM. Pac rom needs a different boot image built.
Also note this is only built for a p930, I do not have the other models to test this rom against
USE AT YOUR OWN RISK
I take no responsibilities for any damages

P.s.
I have seen a BSOD, (it is rare) upon investigation the only weird thing I found was that "ps" listed a dozen processes but does not return. Every other command seemed to work fine. I have not found anyone that can explain what that means or how to troubleshoot this further.

if u can please enable a GPU overclock, im gamer and youtuber if doesnt have GPU overclock i cant play games without lags and do screencasts, a overclock to 320 or 350 mhz it perfect! gpu overclock doesnt need only for my but for any gamer that play MC4, nova 3 and onther high games...
Thank you for your efforts!
I think what is missing from the current CM11 builds is a newer kernel...
I know it is much work, but do you have any plans to update to ION or even a 3.4 version?

As I understand all of our kernels have been based on a gingerbread kernel!? Could someone inform us on what this really means?
P.s. Thanks for the kernel btw! Can't wait to try it. I tried CM11 before and was getting tons of BSOD/reboots, which may have been due to incorrect voltages. I've been stable for days on CM10.1.3 after I applied the correct stock voltages. Wind kernel seems to set a strange voltage curve.

All CM releases are based on the opensource code released by LG for the p930. The kernel has been patched in various ways to make it compatible with kitkat. The android open source kernel project does makes it difficult to update the actual kernel so it remains at release 3.0.31.

Looking at upgrading 3.4 kernel from miroslav sphinx kernel https://github.com/JellyBeanNitro/kernel-iproj-3.4/ to make it compatible. Cannot use the patch sets from iproj since they are for a 3.0.31 kernel so I am using the patches from android_kernel_google_msm to update the 3.4 kernel to be compatible. Have it compiling but I am getting an error booting. MDP: unknown ioctl (cmd=c06c6d94) received!

For more information about ION Memory manager check the link below:
http://android-revolution-hd.blogspot.gr/2013/08/the-android-ion-memory-manager.html
As far as I know the kernel we now have is not ION.
For some other devices, developers were able to make new kernels based on this new memory manager. From what I understand - and I am no expert - this solves lots of issues with newer drivers etc. In the other device I had, all the camera issues were gone after the kernel was updated to support ION. Then it was much easier to upgrade it to 3.4.
With such a kernel I guess it will be much easier to have future versions of android for our devices, since generic drivers can be used for all the components of our phone and of course run kitkat flawlessly.

I have installed your kernel and so far so good.
Since you mention overclocking in your first post, could you post a table with frequencies and relative voltage that your device at least seems to be coping fine?
How would you characterize lulzactive governor's battery performance?

With lulzactive governor I am getting around 20-24 hour rom usage provided no BSOD. I will work on a voltage chart. I built a kernel with HONO's voltage and OC tweaks. I also added the 3 governors he had in his as well. Personally I really like the current ROM and my phone wont go above the 1786, but maybe someone elses phone can reach the 1924 ..
However if miroslav_mm posts his 3.4 kernel source I will likely be distracted by for a while -
Nz
I am stable at 1836...I have run multiple times AnTuTu and 3Dmark and it hasn't frozen a single time.
I really hope though that you get distracted with miroslav_mm's kernel. Maybe you could work together and find a workaround for the camera...
Can you build this kernel for SU640, please?
Thank you

Yes, flash cm11 first
I tried through philztouch n didn't accept. It aborted. I'm currently running newest nightly for CM 11 04/25. Haven't tried it yet on this. Get the error 7 when trying to flash
just want to know if there is any update...
I am using CM11 Aug 10 built + Gapps 20140606 built, after flashing this kernel, some apps installed would be disappeared (e.g. Plus, Hangout, Book, Titanium Backup, Firefox, ...)... For Plus, Hangout, Book, these should be in gapps already, dunno where have they gone.
For the others, I could simply reinstall the apps.
Is it compatibility problem of the kernel?
Am I need factory reset after flashing the kernel?

Buffcore oreo kernelSamsung Galaxy S4 i9505 (jfltexx)Release 02 - 11th June 2018
Code:
#include
/*
* Your warranty is now void.
* And other random stuff no-one reads.
*/
Intro
I had never intended releasing this as a stand alone, but had always been aware that it would work.
With BB and Side both being busy and AOSP and OptLos stalling for a bit, the kernel from RR-oreo should I think help a bit to alleviate users battery issues.
What is it?
Buffcore 2.04 - this is a fork of BB's AOSP 8.1 kernel with added fastcharge and battery saving features.
It is the kernel supplied with RR-o release 2, so isn't needed for RR users.
Code:
renamed to buffcore;
sdfat enabled;
fastcharge implemented for faster charging (up to 1900 ac / 1000 usb);
bcmhd wakelocks for rx and tx halved;
libmemcopy and libstring sped up;
io readahead to 1024k;
lower min cpu governor frequency (270);
power efficient work queues;
voltage tweaking user interface;
faster vmstat;
autosmp hotplugging replacement;
mmc crc disabled;
allow for lower cpu voltage;
reduce swapiness;
optimise divide / multiply by power of 2;
added tcp optimisation options,;
set westwood default;
force doze screen off helper;
optimise cbfillrect function;
reduce wifi wakelock times;
nohz: reduce overhead under high-freq idling patterns.
What rom is it for?
BB's AOSP oreo
Side's OptLos 15.1
Installation
Dirty (use with current rom flash)
Extract the boot.img file from the zip (It is not a flashable zip!).
Reboot rom into twrp.
Perform a nandroid backup to be safe, incase you need to go back.
Go into Install, then select Install Image for Buffcore kernel.
Reinstall your prefered root solution (Magisk, etc).
Do not wipe caches.
Reboot.
Clean (flash as part of clean install)
Extract the boot.img file from the zip (It is not a flashable zip!).
Reboot rom into twrp.
Perform a nandroid backup to be safe, incase you need to go back.
Perform clean recomended in your rom thread.
Install rom.
Go into Install, then select Install Image for Buffcore kernel.
Reinstall your prefered root solution (Magisk, etc)
Install Gapps.
Do not wipe caches.
Reboot.
Usage
Some features will need to be forced on (IF desired) and set to apply on boot with an app like Kernel Aduitor, EXKM etc. (Fastcharge, Min cpu frquency used, Power efficient work queues, Voltage tweaking, AutoSMP hotplugging).
This kernel should / will not be compatible with stweaks.
There will essentially be no support with this, if it works then it works, or doesn't.
If it helps you then it helps you, if it doesn't tough, don't moan about it.
It has had a little testing with the roms it is intended, boots fine and seems to provide some benefit.
This may not get updated either - see it as a stop gap for the moment.
Thanks
Thanks due to Drrossum, Kesaras, CR4IGY_BOY for testing for me.
BB for original kernel and Side and TsvietOK for picks.

Of course, we work better and smarter together.
Since Kernels are/should be backward compatible, any reason why this shouldn't work with RR Marshmallow?
Thx!

Backwards compatibility with kernels? Not guaranteed that I know of.
When Oreo kernels use 64 bit binder, it locks out use with ROMs that don't have 64 bit binder defined.
You'd be better trying a sidecore kernel for nougat as an intermediate, if it works then try this. A kernel flash that doesn't work should be easy to recover from if have you stock one on hand ready to reflash. Remember that any mod / root that patches the kernel will need reflash.
SideCore kernel is a no go. A stock RR Nougat kernel also. Do you think some repacking with the boot.img of the RR Marshmallow would help?

if they don't work, then this is a definite no-go.
I think RR marshmallow used the stock CM13.1 kernel, nothing was changed. Your viable choice would be anything cm13 compatible.
Syzrgy & Alucard spring to mind from back in the day.

Alucard can't be found for MM and Synergy is very old (and not sure how stable).
Is there a way to take the (your/lineage) source and compile it to work with MM?

I was thinking the same. Let me try.
Once repacked it boots but it's unstable. After running AnTuTu a few times it restarted every time. Not a good sign.
I flashed it several times on I9505 running the LOS15.1 and everytime I reboot after flash it shows the boot up screen with the phone model and then goes to Download mode. The fix for this non booting condition is to reflash the ROM.

Where is los15.1? Which rom u mean
I meant the Optimized Lineage OS 15.1 builds Version1 on which I tried to install BUFFcore-o rel02 kernel and it didn't work. But i flashed the Lineage OS 15.1 Version2 and it's all working. Good job
Is it possible to change the max frequency? Before compiling? Or manually with an root Explorer?
