Hybrid Kernel is for all AOSP ROMs powered by Android 5.0 aka Lollipop.
The main objective of this kernel is to maximize end-user experience with advance optimizations from CAF and 3.18 mainline kernel along with device specific features - A TRUE HYBRID.
Linux mainstream (3.4.y or torvald's dev git) offers FIXES and UPDATES for all architectures (like x86 as well as ARM)
We DO need these crucial updates to ensure stability and security. There are many CM kernels which are already updated with 3.4.y branch.
Hybrid kernel will keep up with latest wherever required. Don't fall for garbage talks.
Hybrid Kernel is descendant of CHAOS kernel - Kernel for CM11 with bleeding edge CAF updates, features and fixes.
You can play with all the features using SYNAPSE app.
We have developed support for Synapse in-kernel itself, no need to flash UKM or install any other kernel manager apps.
Feature Highlight:
Latest from Google (kernel_msm source + kernel_common updates)
Complete CAF Sound Experience (audio offloading and auto UHQ - ultra high quality)
Synapse Backend Support. Install Synapse app from Play Store.
Sound Controls and Profiles (including Faux sound app support - though you won't need it)
Gamma Controls and Profiles (including Franco Display control app support - though you won't need it)
Advcanced CPU Boost driver with unified hotplug boot, wake boost and input boost controls (Truly engineered for Project Butter)
In-kernel thermal driver (always enabled) and thermal controls.
CAF updates for WiFi driver.
Backported fastest ZRam from 3.18 kernel. (Fastest ZRam with customizable compression techniques)
Enhanced KSM (Enabled by default)
Enhanced LMK (low memory killer) with profiles and controls (Thanks Moto source and @Dorimanx)
Tuned virtual memory and LMK (Tuning based on our R'n'D, you can change as per your wish using Synapse)
Overclock upto 2.5 GHz (Still boots at stock frequency)
Per CPU Total Control (You can control how each core will behave individually - set min/max/boost freq and governor)
GPU Overclock and lower freq steps. (Still boots at stock max frequency)
GPU driver critical fixes and updates for smoothness.
Additional Interactive governor for GPU (thanks to Franco)
MSM Limiter driver (Does much regulation on CPUFreq driver than you can imagine. Check it out in Synapse app for details.)
Voltage controls (UV upto 675 mV. Please note our hardware have diff PVS category and so voltages and stability over diff voltages will differ user to user. Find your poison yourself with voltage controls in Synapse)
3.4 upstream important updates and fixes (100% stable updates for our 3.4.y kernel)
Power-efficient workqueues (Ported from 3.18 mainstream - PE WQ aims at improving power efficiency.)
Enhanced MSM Hotplug Driver + Controls (Base driver by myfluxi - Enhanced further by me, Dorimanx and alucard)
Enhanced Intelliplug Hotplug Driver + Controls (Base driver by faux- Enhanced further by me, Dorimanx and alucard)
CyanogenMod Hotplug Driver (This driver is disabled by default)
Enhanced Bricked Hotplug Driver + Controls (On mass demand. Base driver by showp1984- Enhanced further by me)
Auto busybox installation (Busybox is required by root apps to perform misc tasks. Please note this wouldn't auto-root device.)
Multiple TCP Congestion methods (HTCP is default - can be changed via Synapse)
Additional FIOPS, VR, ZEN and BFQ Schedulers (ROW scheduler is our default)
Additional Classic Interactive, Intellimm and ZZMoove governors (Bacon governor is our default)
DT2W/S2S/S2W/Wake Timeout/Power Key Suspend (All the wake controls you'll ever need.)
Hardware Encryption (Faster and Powerful) (Removed to fix idle battery drain)
Built with SaberMOD 4.9.3 Toolchain (Performance + Power) The toolchain is rebuilt by me from their sources and has optimized few parameters.
CDROM emulation support (DriveDroid support included)
LCD KCal driver from LG G2 (This provides ability to change RGB values using Synapse)
Tuned LCD Backlight driver to save power
OTG Support for all ROMs (Use StickMount app if your ROM doesn't provide framework support to auto-mount like CM12)
MultiROM Supported (Thanks tasssadar)
init.d support to autorun user defined scripts. (Do not mess with it unless you know the conflicting risks)
Optimized RWSEM, AES and SHA1 routines with NEON mode enabled.
You name it, we will have it.*
*You can request any feature you like to see, we will respond for feasibility.
To know all the fixes and changes done, please refer detailed change log in below post.
Installation Checklist:

This governor offers lower timer_rate which helps a lot preventing any gliches in audio.
If we had kept mpdecision binary in place, min freq would have stayed higher most of the times and helped audio glitch BUT that's too much to sacrifice.
Let's give a shot to Bacon magic.

* GPU OC and improvements. (Still it will boot at stock freqs)
* GPU controls for Synapse
* Various fixes from 3.4.y branch
* Misc updates from Chaos
* Add F2FS support (no auto mount due to some limitations in 5.0)
[B]
Hybrid_v1.0-[10-26]-[13-05][/B]
* Initial version with core features and Synapse support!

F.A.Q.
Q. What ROMs this kernel work?
A. It should work on ALL lollipop ROMs so far. If it doesn't please highlight.
Q. Is this CAF or AOSP kernel?
A. This is AOSP kernel with best updates from CAF and 3.4.y
Q. Root is no longer working. What do I do?
A. Install SuperSu 2.27 or higher. We need Superuser app that is compatible with Enforced SELinux.
Q. How do I change kernel specific settings?
A. We have developed SYNAPSE backend support. Install Synapse from Play Store. Do not install UKM.
Q. XYZ is not working as expected. What to do?
A. Describe what ROM you running, whether this issue exist on stock kernel of your ROM, share dmesg log when issue just occured,
share steps to reproduce the issue.
Q. Can you add ABC feature?
A. We already have most features. If you need new any ABC feature, provide link to it's development if available.
Also let us know how will it be helpful. If same is not feasible for me to add or there is no need to add same, I will reply back.

I'll let you know in 5 minutes. About to flash it over B15.
Edit: Sorry for the wait. 1st boot took nearly 20 minutes!
Anyways, works fine over B15. Root works and all.

Indeed good to see you back Neo
Anyways, kernel is running stable for me, any chance to get fiops or sio schedulers in the future?

Good to see this from you neo! Have you set selinux to permissive or enforcing?
Sent from my Android 5.0 Lollipop + ElementalX powered Nexus 5

Can confirm this works on b15! Run amazing so far, good work

Flashed over vomers preview zip and there's something really screwy with hotplugging. All cores are shown as flashing on and off constantly in synapse and frequencies will not go below 1297mhz

What's the min freq? Is it setting itself to 1297 MHz?
I had same prob, so I thought it's something to do with userspace stuff... I flashed eng.stk's kernel and back hybrid one after a boot.
And all settled quite good..
Need to flash entire ROM again to check what may be causing this.
I believe something left from previous kernel?? Were you on other kernel before?

I have just ripped ramdisk from preview ROM which had modified ramdisk to begin with.
Haven't touched anything on selinux in the ramdisk. So, I believe the modified kernel in vomer thread had changed it to permissive.
Anyways, you can change this yourself using Synapse; there is option available to do so under TOOLS tab.

The min frequency was jumping between 1190, 1297 and 1497 I believe! I was just on sykompopos permissive boot.img before
Sent from my Android 5.0 Lollipop + ElementalX powered Nexus 5

Kernel working well with version 14 of sykopompos 5.0 preview.
Feels quite snappy.
Min frequency is giving me no problems.
Thanks for this gem

Welcome back, Neo! I knew that we can't loose you
From my N10

Running syko B15 and installed your hybrid kernel. One problem I can't change gamma profile. It won't apply on synapse.

* Please keep all comments in this Discussion Thread. Any comments not in that thread will be ignored. Feel free to use the DevDB Bug reporting option as you see fit. This is critical in keeping the same question from being asked times in 5 different threads all with the same answer. It was really slowing down development.
* ]If you have problems with frequencies sticking use "No frills CPU Control" and go to Settings and prevent other apps from changing CPU settings
* Although this kernel has now reached "stable" status. bugs still could pop up. please if you find a reproducible bug and decide to post please try and provide a last_kmesg or logcat.
* Versions go as follows: AOSP-JB4.3 = CM-10.2 etc, AOSP-JB4.2 = CM-10.1 etc, TW-JB4.2 = Android 4.2 TW based ROMs, TW-JB4.3: Android 4.3/Google Edition based ROMs

Nice. GPU OC. Party only getting started. Cant wait fot CPU OC.
Sent from my SGH-M919 using xda app-developers app

yeah i've never overclocked the cpu from scratch before. i have it done but it wont boot. i think i'm missing a couple references in source somewhere

Great to see you on the S4 albino! I really appreciated your work on the Sensation.

Oh, this is sweet. Installing it now.
Is the S4 audio hardware compatible with the Voodoo Sound? (Had this on my S1, and it was needed..)
Looking forward to this. :good:

Getting lower benchmark scores for some reason on this kernel.
Sent from my SGH-M919 using Tapatalk 2

hmmm i get 6800 is quadrant with stock cm kernel and 7600 with mine. what benchmark program. if you want try underclocking the gpu by 50 mhtz you can do this with this command
echo "4500000" > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk
i'm considering lowering the GPU to that as it saves battery and might give better performance i'm not sure

I think gs4 uses acpuclock 8064 for its main CPU controll. Check the pll tables and convert the hex to decimals and multiply by 27 if I'm not mistaken.

FAQ
FAQ
This kernel does not have X, Y or Z feature. Please add it !
No such requests shall be entertained.
For this device the closer to stock we are, the better it is. Hence no need for "fancy" useless features/tweaks. The main aim of halogen is to bring performance without compromising stability & battery. And that is what I intend to do.
AND if you really want this or that feature which is not there in halogen, please feel free to compile your own builds.
Oh no ! I encountered a BUG !
Upload the file named last_kmsg that located in /proc/last_kmsg. It contains kernel logs. Clearly state the bug / what you experienced along with your current kernel settings. Bug reports without logs will be ignored.
Recommneded settings ?
Halogen is pre-configured for best. For custom settings please google, do some research and you are encouraged to post your own settings in this forum. You can start here.
My battery drained overnight !! Look at these screenshots...
Not a halogen fault. The kernel does not “drain” battery. On Android devices, the kernel provides a mechanism for keeping the phone awake, called a wakelock. Processes running on the device (e.g. apps and services) can ask the kernel for a wakelock, and the kernel will oblige. So yes, the kernel is technically keeping the phone awake, but only because an app or service has asked it to. It is these apps and services that are misbehaving and causing drain, not the kernel. Doze mode, introduced in Android Marshmallow, is designed to limit the time that apps and services can wake up the device.
All thanks to @flar2 for his excellent post.

Wow,
What is better setting for this Kernel ?

There is not much to set in this kernel at present. Leave it as it is. Tweak sound to your hearts desire !

What governors & I/O schedulers are already included? Just the "basic" AOSP kernel ones for now?

Yes...
But updates will come soon !!!

You simply did it! Thank you so much!
There is a long way to go but I hope you can add more stuff, not forgetting the DoupleTap to wake up the screen

Testing

NEW BUILD IS UP !!!
[ 12 June, 2015. Version --> R2 ]
New features added :-
** 14 new cpu govs added !!!(check changelog for their names) **
** New I/O schedulers added (added tripndroid) **
** New TCP Congestions added **
** Stereo call recording **
and MUCH, much more......................CHECK CHANGELOG.
Did you know ? :-
With the release of R2, Halogen Kernel becomes the ONLY kernel with maximum number of cpu govs !!! (among all kernels for stock/cm of titan/falcon).
This kernel has around 20 cpu govs !!!
NOTE :-
Try reading this guide by @gsstudios before selecting out among the many CPU Govs.
E _N_J_O_Y !!!

This kernel really works for battery life... Smooth and fast and also improves battery life. Appreciate you're work!

there is something terribly wrong... at boot maximum cpu frequency is set to 384MHz, this give terribly long boot time, stuttery bootanimation and longer time for apps optimization after a rom update
EDIT: temporarily solved with an init.d script, here it is if someone has the same problem https://www.dropbox.com/s/qmcdlljjj0klzaf/cpufreq.zip?dl=0

Even I had been facing the bug...BUT I fixed it out and the BUG IS NO MORE !!!
I will be soon releasing the update ! The problem was with some improperly adapted CPU governors which limited the max cpu freq to 384 at boot. I have removed them and now the cpu clocks @ 11190 during boot.
I appreciate your work with the script. Its good, and I hope you will keep supporting my kernel in the future.
 @ktulu84

Available RAM is less than stock CM12.1 kernel - ~900 MB vs ~860 MB. Pretty sure you're already aware of it, but thought I'd highlight it anyway just in case.

Is the kernel stable? i'm using cm12.1 for daily use and some of the kernels i've tried always gave me the problem where the logcat is spammed with something liek "failed to acquire lock" everytime i touched the screen, can someone report?

Yes I m aware... It will be improved in future versions.
However it does not matter much, Linux handles memory in a different way and will release appropriate ram when required. What really matters is whether you are getting a smooth experience or not.

Yes, there are changes in that. As the OP said, it depends on the kernel. Since our device has 1024MB RAM, the remaining RAM gets allocated to Graphics, audio processing, etc. If you are familiar with it, its very similar to Intel & AMD's allocation of RAM to Graphic memory in computers.

FAQ
F.A.Q
Q. How to use the features?
A. Most of the features are controllable via TricksterMod app
Q. How to use ThunderQuake Engine?
A. With ThunderQuake Engine you can control vibration intensity at hardware level. There are 7 levels of intensities supported
Using Terminal Emulator/ADB shell use following command
Code:
echo "your-value-here" > /sys/kernel/thunderquake_engine/level
Valid values: 0-7

Question:
Is it real 1.5Ghz or is it "1.5Ghz", which actually runs at 1.3Ghz but at higher volts (as it happens in most Mediatek devices when one tries to overclock)?

TricksterMod and benchmark scores indicate 1.5Ghz. That's good enough for me.

This was already discussed in my kernel thread. They're real, because the kernel already supports it and we just unlocked the frequency. Also benchmarks indicate that it's real.

NTFS is not supported.
NTFS formatted SD-card is not mounted in system at all.

Thank you very much for your kernel I'm too happy .
I installed TricksterMod app and set dt2w , BFQ IOScheduler , westwood TCP and ZRAM .
How do I set NTFS and CIFS and Multicore scheduler ?
You may also upgrade your kernel to version 3.10.92 , please ?

Sorry, last I remember it was 30% slower than MT6752 (which basically would show no difference than the 1.3ghz clocks).
Maybe I'd have to run Phoronix's Linux workload via chroot if the results are as inconclusive as I remember them. Phoronix's benchs show things like throttling with surgical precision (it only cares about load, not mhz, so when there's sudden gap in performance that would be throttling). Of course I'd have to get the phone in my hands first (my wife rarely let's me to "pet" it anymore ).

The ROM has to support it as well and stock doesn't But a 3rd party app would do it as well, AFAIK.

I do not have a microSD card yet (ordering one soon). What do work with SD-cards, fat32? ext4?
@stefano91av Multicore scheduler is built in, so nothing to do there.
The kernel sources has a lot of backports etc, especially in the arm code. So it's not that easy to get to the latest kernel. I will get there eventually, just give me some time.
I am not an expert at this stuff, learning as I go.
Has someone played with ThunderQuake?

FAT32 definetely does.

My p8000 om eragon 5. Freeze just after reboot.
Flashed it with fla****y. Tryid booth versions.
All version of Blues kernel works without problems.
Any suggestion?

wierd micbanand..
I am still on eragon 4. My and Blues kernel is using same source, so should be no difference. Tried with Rashr?
Finished with updating to 3.10.92. Uploading after I have tested it a few hours...

Uploaded new kernel with 3.10.92 added. There are so much debug stuff in the sources it's crazy. Found some hidden stuff when I updated..
Now I am tired. Was a lot of work..

Thanks. But freezes. Reboots frezes. Tryid all 3 kernels. And allso updated to eragon 5,5
This time flashed with Rashr.

Now I'm trying v1.21.
With v1.20 there were jamming in the videos of facebook when I received messages from whatsapp . In addition, the score was AnTuTu 29000

heh that bad. I did some stupid stuff there.
I got almost 35000 with 1.21.
Will try to improve on the wakeup lagg tomorrow.

I too can confirm that flashing this kernel over Eragon 5.6 results in a bootloop. Well, it's not exactly a bootloop, since the phone finishes botting and you can also unlock the screen, but less that a minute it restarts, and this happens over and over again. I tried rebooting the phone into safe mode before it reboots itself, but in safe mode it also reboots suddenly.

wierd. Every kernel I have build has booted fine for me.
New version with updated sources ++ coming later tonight.

Waiting for new kernel

Kernel Adiutor OTA Update Information
Now for CyanogenMod And AOSP Based ROM, Hana Kernel Offered OTA Update feature for kernel update using kernel adiutor app for CyanogenMod Based ROM with "download" feature in kernel adiutor.
You can download new build in that menu included ; introduce, kernel feature and changelog update. Now i'm still try to enable it on LineageOS too, i'm just need to wait confirmation from the admin .
For anyone want to install this kernel, can access too using KA. just like normal download and installation for kernel :laugh:
Have fun

Kernel Adiutor Information
For Kernel Adiutor Usage
During new stable version of Kernel Adiutor have problem with CPU temperature, now we should use BETA build from Kernel Adiutor to get fix for that problem.
And for set on boot configuration, i'm not recommended it again , since that only can make kernel error during boot up process.
So set kernel when system is already boot is best option for stability and performance.
If kernel adiutor to hard for configure, then you can try Device Control app to manage your kernel.
This app is almost same like KA but it's little simple and more friendly for configuration

[INFO] Double Tap 2 Wake & BETA Build
For Double Tap 2 Wake
Try to use kernel adiutor and check in wake tap, after that choose DT2W and enable it using "full'" option and then let's try DT2W features with vibration on mimori kernel
NOTE : BETA Build For Testing (Not Stable)
github/build
For BETA, try to look date for kernel. Find latest one, and anyone can test latest beta if don't want wait for stable update. I can't promise to make fast update for stable source, i don't want to make any problem. so it's better stay at beta and whenever it ready, and it should release on thread :victory:

Thanks.

Small notes
The kernel is tested on C6902/C6903/C6906 model. Not sure about other Z1 variants (don't confuse with Z1c). Testers are welcome
As written in the thread name, make sure you're on ROMs mentioned in the thread name. Please report if other ROMs work with this kernel
The kernel is based on @SuperLamic's msm8974 kernel source, and other features were cherry-picked from other sources as well. Original credits goes to them
For dt2w, tap 2 fingers at once on your touchscreen (as mentioned in Modified-kernel thread)

Reserved for future usage

Twrp included ?

Any plans for oreo version?

Is it possible to disable dt2w?
I remember way back it was usually done by modifying a file like
echo "1" > /sys/android_touch/ *some dt2w file*

Added support for Adreno Idler (reduce high GPU frequencies usage due to msm-adreno-tz overhead), and Simple GPU algorithm
Added governors: zzmoove [DEFAULT], elementalX
Disabled mpdecision and thermanager by default (through my own ramdisk implementation, may support other ROMs for sure, as confirmed with Carbon N and LOS N)
Added support for zswap (ported from Samsung msm8974 kernel source)
Added IO schedulers: zen, fiops (default is still ROW)
Added 100MHz GPU step (should reduce battery consumption on light usage)
Added support for Dynamic Fsync (disabled by default), powersuspend driver (default: HYBRID mode)
Reduced CPU standby voltage
Fixed dt2w deep sleep state (it should function properly now)
RZ v2.0 is available on my Drive folder. Please checkout OP for download link!

I'm using the very first version of AnyKernel with very minimal patching commands
Somehow it's pretty hard for me to adapt to a newer AK version so I decided to write my own noob-friendly ramdisk patching script instead (compatible with all Z1 AOSP boot.img)
My kernel boots currently on LOS N and Carbon N. For RR, idk why it bootloops. Probably need some other kernel commits maybe?
Sent from my Xperia Z1 using XDA Labs

Runs nice..but I needed to flash the stock kernel from superlamic lineage os and then flash this kernel because the phone went in to a bootloop on the sony logo.
Just a reminder to what to do when your next update is coming
edit: no its magisk thats acting up.. wont't boot when installing this after flashing the kernel
Phone is booting with magisk on stock kernel so something is not right.
I don't have more time atm for this so im gonna let it be
