r1 - 20150415
Hi everyone! I'm zwliew, and I'd like to present a personal project called zwliew Kernel. The Redmi 1S is truly a great device for the price, and I'd like to improve it further with what CM 12.1 brings to the table!
So here's r1 of zwliew Kernel. The flashing process is really simple since it is just a boot.img file. Simply use an app like "Flashr" or "Flashify" to flash it, or you can fastboot it too.

Removed to investigate a small issue
General changelog:
http://128.199.239.125/armani/changelog
Now I'll explain a bit on the changes I've made. These changes are meant to make the kernel simply a "flash and forget" kinda thing. Flash the boot.img, and experience improvements without much tinkering. Of course, any advanced features wanted, feel free to request and I'll consider them. Currently, I'm considering on adding KCAL control.
I've changed the min freq to 787 MHz. Why you may ask? According to research from CAF (the software developers of Snapdragon OSS kernel and others), 787 MHz, being the max frequency at nominal voltage and L2 freq, is the optimal minimum frequency. This will allow the CPU to complete tasks and threads faster, thus apps can enter IPC more often and overall save more power. So far, this has brought about performance improvements in everyday tasks and battery life has not taken a hit.
I've also merged general optimization patches from both upstream and Motorola. Motorola's patches optimize the low-level memory operations like memcpy and memmove. An upstream patchset optimizes the crypto operations like SHA1 and AES, making use of architecture features like NEON. Some other patches improve the cpufreq subsystem and others.
The KGSL and devfreq subsystem has been improved with patches from CAF too. These subsystems improve the overall GPU performance.
Thanx for the new Kernel...Is it Compatible with Cm12.1 RC2 or just only for RC1 ??

Bro can you provide an ss that it is fully bootable ... Because With This kernel source so little dev able to compile it fully to boot.img ... Thanks in advance no offence none of your fault it was'nt bootable as xiaomi not releasing all the source code
Booted on cm12.0 but facing phone fc and keeps rebooting..
Which app should we use to control this kernel features.... @zwliew

Yes I'm also waiting for some proof it is compatible with LP from devs...
Sorry, this was too early a build and I didn't test it properly. Once it's the weekends (or Friday), I'll test it properly and release a proper working version.
Can you make it compatible with mokee ROM as well?

Mokee official build
Will this work on mokee official nightlies..???
Anybody try it on (5.1) Resurrection Remix?
Sorry guys! I made a small mistake in one of the commits so r1 was bad. Currently, r1.1 is working well on my Redmi 1S. I'm undergoing a little more testing and it should be ready for release by Saturday.
P.S. Disregard the r0.1 title, it is just a placeholder release title.

Changelog:
http://128.199.239.125/armani/changelog
Changes are pretty much the same as before, with a few new additions.
Firstly, I've updated the interactive governor to match CAF's codebase. Currently, I'm undergoing testing to see whether it is a capable substitute the ondemand governor.
I've also merged a couple of patches to use interruptible waits over uninterruptible ones in several subsystems. This will reduce the load average by an order of 10(!).
There should also be better power consumption as I've enabled more idle power modes for CPUs to go into deeper idle states.
Hi
Do you think you can add the manual voltage regulator in the next versions? It will be best to try the optimal frequency/voltage than to change just the frequencies.

Hi! Since the OP only mentions "sultanxda branch" is it safe to assume that it has all the latest patches for 5.1.1 as well? Or is it only for MM roms?
Sent from OnePlus One
From github it seems it's mm only.

Thanks for the response. I'm waiting for the Omni team to fix the nasty Network Switching Mode bug to jump to MM. Also, doze is pretty useless on whatsapp and other push notification apps, and they eat most of the battery. So no big reason for me to jump to MM as of now. I wish google could fix the Mobile Radio active bug before releasing MM to public.
Does this have multirom support?
Kexec Hard boot support is not yet added in this rom, but according to me sultanxda has already used it in her kernel, so the features of sultanxda are already present plus i have added some stuff and will keep on adding it So have patience, for now CM is the priority and then CAF
Regards
Andy
Multirom support?
Kexec hardboot is what we call multirom support... And sultan has already committed in his source. So it will work. So please give a try and report.
#Andy1911 sorry for a NOOB question - but how is your kernel better/different from Sultans CAF kernel? What are the benefits?

Actually I have added some features to the kernel. Like hotplug and governers. They help us in handling device in more better manner. Sultan has already added features for stability and performance but I am trying to optimize more I can. It will make the device run more better and smoother. Features like fsync help device to manage files more easily. Franco sound driver helps gain volume more than stock can give. Such features make our life easier nothing else and device becomes smarter just as it has its own mind or kind of stuff. It can handle itself more precisely. Like Controlling it's own frequency and handling clock. You can give a try to these features and then see the difference. That's it. I made it because unfortunately @ak is not working more for the device and the features I desired were not available In the kernels available now. So I made it myself nothing elz...
And remember no question is a noob. Your desire to gain more knowledge is really appreciable..
Thanks

One more question I noticed the status in op says testing, what does that say as far as how stable your kernel is right now (I know what testing usually means but wanted to see if there are any issues to look out for)

No issues right now, I am actually not USING CAF, I love CM, so i havent tested yet, but my friend said that there are no issues and he is running bugless right now, So I will expect a complete review and then declare it as stable

Introduction
Oxygen Kernel is based on stock Samsung source code taken from Samsung Opensource Release Center with sole aim to provide better performance, stablity and battery backup than stock kernel. A kernel tells the hardware in your Android device how to behave, kind of like your mommy tells you how to behave. You can modify how fast your processor runs by over or under clocking it or optimize your system for battery life.
Oxygen Kernel is always up-to-date with latest patches from kernel.org
Known for maximum stability and smooth performance
All the Source Code is available on github
Kernel Info
LINUX: 3.18.138
SAFETYNET: Green
SELINUX: Permissive
TOOLCHAIN: Google's GCC 4.9
Compatible ROMS
All AOSP 8.1 and 9 ROMs
All OneUI Pie based ROMs
All Touchwiz 8.0 and 8.1 ROMs
Features
Here are the major features of the kernel (feel free to explore Github)
Up to date with the latest stable Linux version
Full -Ofast build with graphite optimisations
Removed a lot of useless debug and logging options
Disabled TIMA, KNOX, DM-VERITY,etc
Awesome battery life and smooth performance
ARM enhanced performance patches
Overclock CPU up-to 1.7GHz and GPU up-to 1146MHz
GPU Voltage Control
CPU Governors: conservative, interactive, ondemand, performance, powersave, userspace (default: interactive)
I/O Schedulers: bfq, cfq, deadline, maple, noop (default: maple)
Powersuspend and State Notifier drivers
Dynamic FSync, FS fsync toggle on/off
Frandom driver for 10-50x faster random number generation
Spectrum Support (a simple, profile based kernel manager || now integrated into Oxygen Control)
Disabled CRCs by default for 30% performance boost
CDROM emulation on mass_storage (compatible with DriveDroid)
Wireguard support
Boeffla Wakelock Blocker
Oxygen Control App Features
Full CPU and GPU Control
Boeffla Wakelock Blocker
Spectrum Support
Samsung Hotplug
CRC Control
And many more!
These features are only available through Oxygen Control App
Download Oxygen Control from Github Releases
Warning: If you come from some other custom kernel or have any issues, you should dirty flash your ROM before flashing Oxygen Kernel to avoid problems.
Reflash ROM -> Flash Oxygen Kernel --> Flash Magisk if you want to root
If you are upgrading between Oxygen Kernel versions, just flash the kernel zip. Also uninstall or clean data of any kernel control app you're using.
Going back to stock: You can backup your boot.img with TWRP before flashing Oxygen Kernel and restore the backup whenever you want to revert.
1] This kernel removes forced encryption, if you face "encryption process failed" error upon reboot then you need to format /data. This is generally needed if you are installing this kernel on stock tw rom.
2] In OneUI Pie ROMs you may get a warning at boot saying "There's an internal problem with your device". You can safely ignore this warning and causes no harm. It's due to some mismatching KNOX/mobicore stuff. I'll fix it soon.

DarkLord1731 an excellent work, I have been testing it for several days and there are many improvements that for the moment and perceived.
But I have a small bug ... I have an unlock pattern configured that when I am connected to the Wi-Fi network, I do not ask for it every time I lock and unlock the screen, when I turn off Wi-Fi if you ask me every time ... someone more with this problem? (G translate)

I might have found a bug, or maybe it is just silicon lottery. When i set my gpu to max freq 1146, it stops working completely it says 0 Mhz and fps drops immediately.

Successfully installed in j7 pro G/DS though not rooted, any suggestion on how to root? the last time I rooted having issue on screen unlocking delay that I have to unroot.
Sorry for such a question, but it says "Any AOSP Oreo Roms", does this mean any or the only one found in the ROM Forum Secton for this device?
Hello,Can it work on ROM][7.0][NovaOS][J7 Pro J730F][NoteFE Full Port]?

ABOUT:
This is my personal kernel project, which I looked to be a stable kernel for daily usage, with useful features only, and to have a half term under performance and battery life for Xiaomi msm8996 devices. Inspired by projects like Flash Kernel and ElementalX Kernel
"While I am not a super star kernel developer, I do know my way around it." (Chancellor, Nathan - 2017)
PROJECT GOALS:
Keep kernel up-to-date with lastest stable Linux Kernel version (3.18.133)
Offer the user the best balance between battery life and performance
Just useful features. Features may be included only as needed (Read FAQ section to know the features that I won't add in anyway)
FEATURES:
Here are the major features of the kernel (More details on the Github repo)
Up-to-date with the latest stable Linux Kernel version (3.18.123)
Mainline Linux patches for CFQ
Several subsystems converted to use power efficient workqueues
Hides bootloader unlock from SafetyNet (can still fail through other means)
Available to flash with AnyKernel2 (thanks to @osm0sis)
Users facing features:
KCAL color control
USB Fastcharge
Adreno Idler
Boeffla Wakelock Blocker
INSTALLATION:
Boot to recovery
Flash kernel zip
Reboot
Yay! You've installed the kernel :victory:

F.A.Q:
Q: Are you Planning to support MIUI?
1. A: No.
Q: Could you include feature x,y and z in your kernel please?
2. A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I won't promise that I will merge every request but I will always take it into consideration. I will NOT add:
Overclock or underclock of the CPU and GPU (Except for the cases that the device has a underclock on both or in just one, then it'll be considered)
Undervolt
Any other governors except the "kernel stock" ones
Any feature that just one or two people is going to use
Q: I'm having an issue, can you help me?
3. A: I'm not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue. If I can't reproduce reliably, I'm not going to fix the issue. (Extracted from Nathan Chancellor's Flash Kernel Thread)
Q: The kernel is f*cking up my battery! Plz...
4. A: Stop right there. The Kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone. If verified the clocks are always online and on the max clock, then it'll checked out what's happen. Anyway logs are necessary.
THANKS TO:
@nathanchance
@flar2
@franciscofranco
@LuK1337 and Mi5Devs
@xNombre
Any other developer that I might forgot
ADDITIONAL NOTES:
ABOUT KERNEL USAGE IN OTHER ROMS THAT ARE NOT MINE:
You are free to use the kernel if you want. The only thing that I'll request to do it's to keep the kernel name. If you have modified something, just add a "-Mod" in the final of the kernel name or anything that states that the kernel has been modified, not by me, but by ROM maintainer.

AOSP ROMs (LOS, AEX, PE, Cardinal etc.). I'm not planning to support MIUI, at least not as for now.
How does it interact with CPU clocks? I wrote something in my first post on those forums half an hour ago (https://forum.xda-developers.com/mi-note-2/help/issues-cpu-battery-life-horrible-xiaomi-t3849717), could it improve my current issues?
I don't mean overclocking at all.

I've underclocked the EAS kernel build to 2.2/2.15GHz on big clusters to handle a bit with battery and not heat up a lot the device. I actually don't have the scorpio, but also I didn't have any problems like you've wrote on your post on Natrium (Mi 5s Plus) not on Capricorn (Mi 5s) as my testers have related to me. Also that point of bad thermal management was found out by @Alberto96 and his AEX builds are fine with thermal related stuff. You can try them to check if you got it fine. Also you can try FloppyKernel for MIUI by @Jonas Cardoso (https://github.com/JonasCardoso/and...-Lite-Prime-Pro-01102018-Linaro-Oreo-MIUI.zip) to check if also solves your problems with the scorpio's MIUI 10 stock.

The EAS kernel very good for battery life but it impact performance so much, because 1 core of each Big n Little CPU get offline. Is it possible to just make it underclocked with big CPU limit between 1,8-2,1GHz and Little CPU between 1,516-1,59 (or @Any freq you think is the best)? Or it's the way the energy aware work? I think all core online with low freq is better then 2 core offline with big freq.

Big clusters are already on 2.15Ghz. Little clusters i kept the "stock" freqs. Actually EAS is better for graphics performance, not battery performance, which has as consequence bigger battery consumption.. Anyway, I've received feedbacks of the same thing on Natrium (my device) and already looking to check if I get it fine with the performance then

Well.. it's good for graphic and battery too on my side, I can play games a bit longer with your kernel

Great.. thank you.. waiting for your next build. BTW Little CPU stock freq gave too much heat when playing game, could you downclock it a bit
If anyone got the cores always running on the max freqs on EAS Kernel, set governor to ondemand and then set again to schedutil. That's a workaround for now

Hello everyone, this is my personal kernel for the OnePlus 5. While I am not a super star kernel developer, I do know my way around it. Hopefully you enjoy :highfive:
NOTE: This list fluctuates with versions, it will not always been 100% up to date
Here are the major features of the kernel (feel free to explore Github)
Based on GzR kernel
Up to date with the latest stable Linux version (4.4.159)
Up to date with the latest CAF branch (kernel.lnx.4.4.r27-rel)
Mainline patches from Linux, focusing on bug fixes/security
Mainline CFQ scheduler improvements
Several subsystems converted to use power efficient workqueues
Backlight dimmer
KCAL color control
CPU Input Boost driver
Devfreq Boost driver
Sound control
Wakelock control
Westwood as the default TCP algorithm
Built with the latest Google Clang 7.0.2 toolchain
Hides bootloader unlock from SafetyNet (can still fail through other means)
Disables dm-verity
Does NOT modify decryption status
Flashed with AnyKernel2 (thanks to @osm0sis)
Primary: https://androidfilehost.com/?w=files&flid=283181
Through TWRP:
If you are on a custom ROM:
If you are on the kernel that came with your ROM: flash the kernel zip and reboot
If you are on a custom kernel: dirty flash your ROM zip, flash the kernel zip, and reboot
Upgrading from one Reaper version to the other:
Just flash the kernel zip and reboot
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably, I'm not going to fix the issue.
1.2 Q: What ROMs are compatible with the custom builds?
1.2 A: My daily driver is GZOSP so I test all the builds on this ROM but this kernel should work on other pie ROMs. If you are using a ROM with no issues, let me know and I'll add it here! If you are having issues, following the above steps and I'll attempt to fix whatever incompatibility there is. If I can't do it without breaking GZOSP compatibility, you're out of luck.
1.3 Q: Can you add xyz feature?
1.3 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration.
1.4 Q: How do I control the kernel?
1.4 A: I want to be very clear: the kernel does NOT need to be tuned to be useful. Most of the improvements are under the hood and don't require any user intervention to take advantage of them. In fact, if you don't know what you are doing, you could degrade the experience. To control the user visible features of the kernel listed above, I recommend using @flar2's EX Kernel Manager.
1.5 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.5 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.

Added to the OnePlus 5 Index Thread here. Also, a suggestion @FRNKSTN, do include the [KERNEL] tag in the thread title, because at the moment the title doesn't convey whether Reaper is a kernel or a custom ROM.

It's working good still. It should theoretically work fine with Oreo until OnePlus releases Pie or until there are too many Pie specific commits in the kernel.
