Leankernel: ( JB4.2 - 7.1, JB4.3 - 8.3 - , KK 9.0 beta 11/25)

Ok guys i have got permission to bring over lean kernel and offer support for it on xda. I will keep this post up todate with all the most recent kernel updates and news. All credit goes to imoseyon as the original op and rootzwiki for original posting. I am posting this with full permission and support from imoseyon
Mod Type:: Kernel
Difficulty:: Very Easy
Mod Status:: Stable
Apply In:: CWM Recovery
Requires Root:: Yes
Exp builds are also up and includes a bunch of Android/OMAP updates not in stable.
SOURCE:
ICS
JB
This is a minimalistic Galaxy Nexus kernel. My philosophy is to keep the kernel as lean and stable as possible, at the same time to keep the kernel as modern and close to latest mainstream linux as possible. You will see that my kernels will lack some of the bells and whistles from other kernels.
sorry host4droid is still down. Mirrors:
kk4.4 LK 9.0 beta (use at ur own risk)

CHANGE LOG JB 4.2
FEATURES
Patched to latest in Linux 3.0.x branch.
All unnecessary kernel components removed to make kernel lean and fast!
OC to 1.65ghz. Boot speed is maxed at 1.2ghz within kernel (in addition to ramdisk) for stability.
User voltage control
InteractiveX V2 (screen-off hotplug of cpu1) added. Select it using setcpu if you want to use it.
Ramdisk tweaks (sysctl, vm, filesystem speed, etc.)
SWAP & zram (next generation compcache) support. Run "zram enable" in terminal.
init.d support in ramdisk.
lk.conf for basic kernel configuration.
HotplugX governor (Hotplug optimized and modified for screen-off suspend).
wakelock tweaks for wlan and lte modem
lkflash - script to flash latest versions of leanKernel from Terminal (type "su" without quotes, hit enter, then type "lkflash" without quotes and then hit enter)
checkv - voltage checking script (for custom undervolting) - detailed at bottom of this post.
checkt - script that displays 1) your current temp, 2) # of times you were throttled due to temp "recently", 3) CPU trim type, and 4) CPU silicon type, etc.
Fast USB charge (by chad0982) and "ffc" toggle script by me. (Open terminal, and type "ffc" without quotes then enter)
ColorControl from both CM9 and Ezekeel (compatible with all ROMs). Helpful posts: 1and 2.
TempControl - sysfs interface to control the CPU temp threshold. Read these two posts: 1 and 2.
Variable GPU OC - sysfs interface to select GPU max speed between 307MHz (stock), 384MHz and 512Mhz. The changes take effect immediately. Check FAQ for more info and how to use it.
Custom SR Tuning - override kernel default minimum voltage for SR calibration.
SoundControl
Gamma Control
ROW scheduler v4

FAQ
How do i change voltage? - Use the latest version of setcpu, leantweaks, cputuner, or your ROM's built-in tools.
Do i need to wipe dalvik/cache? - in general there's no need, but it doesn't hurt so if you have time go ahead. Posted Image I don't wipe.
​Can we OC higher or add more frequency slots? - You can find the extra slots in my experimental versions.
​Will this work on GSM gnexus as well? - It should. I don't have a GSM phone to test so let me know if it stops working.
What is interactiveX V2? Read this post and thttp://rootzwiki.com/topic/13092-kernel-leankernel-minimalistic-kernel-120-123111/page__view__findpost__p__342571
Are you getting Screen-Off/Sleep-Of Death (SOD), general instability, or unusual battery drain?
Before you post here (especially if you're running the experimental version), try the following steps in order:
0) dude, disable screen-off profiles if you're running interactiveX.
1) If you're running the experimental version, do you have 180mhz/230mhz and/or 1.42ghz slots enabled? If so disable them both!
2) If the above doesn't help, do you have custom undervolting enabled? If so disable it! (keep in mind that the kernel is already undervolted by default).
3) If the above doesn't help, are you using interactiveX or hotplug governors? If so change to interactive.
4) If the above doesn't help then you should not be running the experimental version. Install the stable version and try both interactiveX and interactive without custom undervolting.
If you're still getting SOD with stable/interactive, report it here.
What about call-recording? - First the app needs to support Galaxy Nexus. Find out if it does and then find out from the author of the app what kernel changes are required and let me know.
Should i set up screen-off profile? - ICS kernels have built-in screen-off profile for all governors at 700mhz. So you don't need it unless you want to set it lower than 700mhz. In general there isn't a whole lot to gain by setting it lower.
Hotplug vs interactiveX? - Read this post. HotplugX vs interactiveX
What is zram and why do i need it?
zram basically takes a portion of your RAM (10% using my script) and turns it into a compressed swap device. So in layman's terms you're extending the size of your memory (potentially from ~700mb to close to 1000mb depending on the compression ratio).
To answer the 2nd question, no you don't really need it but if used properly (using custom LK zram script) it could help you in two different ways:
1) Android OS is based on Linux OS and the OS will try to use a growing portion of your RAM for file and inode caches and if you keep your phone up without rebooting after a while you may notice things getting a little sluggish. That's because the OS is not doing a good job in dropping the caches and freeing up memory for the apps.
2) more RAM and tweaked minfree (also handled by custom LK script) could potentially allow your apps to stay in memory longer (this may or may not be desirable based on your preference of course).
In conclusion, I'd say if you're curious it doesn't hurt to try. To revert, just type "zram disable".
What's the low-down on the GPU OC?
My kernel's GPU is now set to stock 307Mhz by default. You can adjust that by using Variable GPU OC (see a separate FAQ entry below).
When you go from say 307 to 512Mhz, you will not experience near double performance increase. Due to the factors outside the GPU module (ie. memory bandwidth limitation), you can't truly OC the GPU. In fact, most people can't tell the difference between 307, 384 and 512. Nenamark2 will roughly give you the following scores: 307/25fps, 384/28fps, and 512/31fps.
Some of you have seen the note from Colin, the Google kernel engineer, not to OC the GPU because using the OV_UV voltage slot will drain the battery. My kernel uses the same voltage for both OV and OV_UV slots. So there's no danger of battery drain there.
Why are the IO benchmark test scores lower than another kernel?
Some of the kernels out there have fsync disabled to increase benchmark scores. I believe that is unsafe and could cause data corruption. I do have hooks in my kernel to disable it but I don't use it.
In real world there will not be any user perceivable difference whether you have fsync enabled or disabled.
Is there a way to tune hotplug via sysfs?
yes. Advanced users only!
My phone doesn't seem to be deep-sleeping, what gives?
(assuming you checked in the right place like cpuspy) In terms of deep-sleep, there's not a whole lot going on in the kernel. It works or it doesn't - and I can assure you that I test every release (well almost every release) for deep-sleep before I release.
19 out of 20 times it's either 1) some sort of background process that's preventing your phone from going into deepsleep, or 2) something's misconfigured in your ROM, or both. Also connecting to USB will prevent phone from going into deepsleep.
I'm having unusual battery drain - help!
First of all, our gnex has very poor battery life while in active use. It's downright horrible while screen is on - screen is definitely the main culprit and there's not a whole lot I can do about that.
Custom undervolting can help or can hurt. This is mainly due to SmartReflex (class1.5) which auto-calibrates the ideal voltages for you. In fact, with SR you don't really need to use the custom undervolting feature for frequencies other than the 2 lowest. It does a great job calibrating higher frequencies. I personally don't touch it.
The "notrim" versions are an exception because I had to disable SR1.5 for the trim override to work. There's no auto-calibration going on there. Feel free to mess with custom undervolting on the notrim versions.
Now, if you've already accepted the horrible battery life while screen is on, but have questions about battery drain while idle - read the next question.
I'm having unusual battery drain while screen is off, or phone is sleeping - help!
First, let's find out if you're phone is going into deep-sleep. Install CPUSpy, unplug phone, turn off screen, and leave the phone alone for 5-10min. Turn the screen back on, launch CPUSpy, and see if you see an active entry for Deep Sleep. If so congratulations - read on.
If you've determined that your phone is not entering deepsleep by using the above method, read my entry above that says "My phone doesn't seem to be deep-sleeping". I've heard that removing SDM.apk helps as well as rebooting the phone. Also try turning your bluetooth on and off, and launching camera app and closing it.
If you've determined that your phone is entering deepsleep fine but still feel like battery drains, read the next question.
I'm having unusual battery drain while phone is in deep-sleep - help!
First make sure you are absolutely positive that deep sleep is working (read the previous question).
While on my kernel *and* connected to Wifi, you shouldn't drain more than 1% battery per hour *average* while in deep sleep (based on 5-8 hour continuous deep sleep). With wifi turned-off, my guess is probably no more than 1-3% per hour, depending on signal strength.
tip 1: If above is not happening for you, first charge the phone all the way and reboot. Let things settle a bit - give it a day or so. If you're using Battery Monitor Widget (which is not accurate for gnex), things should eventually settle between -2mA and -60mA per sample.
tip 2: Install BetterBatteryStats and look at which wakelocks dominate. Google search for names of the wakelocks to see how you can fix them.
tip 3: http://checkthis.com/d87t
If nothing seems to help, you can try the "notrim" version, but stick to speeds between 350 and 1350 (don't use OC slots). The notrim version has SR1.5 disabled which could help for those of you with drain issues on my other kernels.
What is tempcontrol and how do I use it?
First, read these two posts: 1 and 2.
Although tempcontrol was designed to be used with the experimental notrim builds because the cpu gets hotter in notrim frequencies, you can actually use tempcontrol to throttle lower frequencies. I haven't tried myself, but theoretically you can set your top speed at say 1.2Ghz and use tempcontrol to throttle at say 60C (instead of the stock value of 63C) resulting in slightly cooler phone. Theoretically.
What is SmartReflex?
SmartReflex performs continuous dynamic voltage scaling around the nominal operating point voltage according to silicon characteristics and operating conditions.
My stable and experimental builds will have SR Class 1.5 enabled by default.
You can disable SR via sysfs
How do I use Variable GPU OC?
You can use Lean Tweaks by Jake, or use the built-in "oc" script. Both leantweaks and my oc script will create an init.d script so the setting sticks at boot. My "checkt" script will also show the current GPU max speed. Note that 512MHz will probably not work for everyone.
307Mhz (stock) is set default by the kernel.
Open Terminal, and type for stock speed of 307Mhz: oc gpu 0
for 384MHz: oc gpu 1
for 512Mhz: oc gpu 2
What are the available sysfs options?
Check this post (thx byrong)
Which governor should I use on JB?
As usual I'd recommend trying all the governors and see which one works best for you. Stock JB, however, is optimized for interactive. The OS will automatically modify various interactive governor parameters on the fly while you're using the phone as part of "project butter". Namely, the following parameters are constantly adjusted by the OS: boostpulse, timer_rate, min_sample_time, hispeed_freq, go_hispeed_load, and above_hispeed_delay.
I hope this helps people if there is any other information you might want added just ask and i will do my best to come up with a comprehensive guide.

Did you ask Imoseyon before you posted this?

Thanks for bringing the thread over to XDA. Hopefully you got the necessary permissions, for the sake a peaceful thread. Its good to have most developments of the GNEX here and I finger tip away.

I've heard a lot about this kernel!

yes this is with his permisson

No i didn't ask him but i did put all due credits in it and it is in every other gnex forum but the sprint one all brought over by other people so if he has a problem with this he can feel free to pm me and i will get it removed i just figured it give us some easier access to his great kernel. In no way am i claiming this to be my work all support should be directed at the original thread op. I was just trying to make access to his kernel a bit easier for all xda users

That's all hunky dory but just doing things without asking the developer is just not right. Regardless if he has an issue or not. Its like you make something you work diligently on and then somebody just posts it somewhere else.
I dunno maybe its just me but its just common courtesy.

Thanks for linking. You can still ask dev for permission but I get what you're trying to do. I prefer xda since this is where I have gotten help with every phone since my nexus 1.

Well i have gotten permission to post this from imoseyon and to keep this thread updated on xda sprint forums for him so it looks like we are all set he got back to me alot faster then i thought he would so every thing should be all good guys
and yes jayare313 i am so used to finding every thing i need on xda some times it s a pain having to check 3 or 4 sites to see if any of your mods for your rom are updated

Sorry. 3 issues here:
1) I need to verify permission from the developer and he needs to verify that he is going to support it here. If someone downloads it, flashes it, and somethings wrong.......who is going to give answers and support it? We have an active community who can help, sure, but the developer has to actively support it here. If he were ready to give support here, he would have posted it here already. And even then it would have to go in general unless he started the thread.
2) There is no source provided in the OP. Kernels must be GPL compliant and listed in the OP.
3) If you did not create it, do not post it in the development section.

Alrighty. Everything should be good now. I'll be keeping an eye out.
OP will be updated soon, with source and I've spoken to the developer.
Thank you guys.

[KERNEL][BETA/TEST][CM12][1/12/15] E980 Kernel+ V0.8.1

E980 Kernel+​
***I am not responsible for you bricking your device or causing any other unwanted outcomes to your device. Be careful and smart. If you don't know what you're doing you probably shouldn't be flashing this.***
This is the E980 Kernel+​The end goal here is to have a kernel with more features and potentially much better battery life. I can only guarantee it will work on E980, not sure if it will work on other devices. I also do not know what ROMs it will work on. That is up to you to share. Rule of thumb is, if it's CyanogenMod, it'll work.
Suported Devices:
E980
E988
***If you are interested in building your ROM with my kernel, you have my permission to do so. However, if you could just let me know, that'd be nice. Also a credit would be appreciated but is not necessary either.***

HOW TO BUILD​
At this point if anybody wants to try out the kernel before I make releases, you are free to compile it yourself. I would like to ask that you do not share compilations just because I like to track how many people download and use the kernel through my goo.gl links and the afh download counter. I don't like it when people rehost my kernel since it gives me misguided numbers on how many people are following my work. It's just personal though, I'm not going to stop you. I just like it because it gives me an idea of how many people are using my work and kind of makes me want to keep working on it since I know how many people still use it.
Anyways, I'll leave instructions to compile right here:
This is assuming you're using a Linux distro (VM or not, has to be 64-bit) Pretty much everybody recommends Ubuntu, and that's fine, but if you want my suggestion Mint runs like a dream. Anyways to building!
You'll need to get the required packages. I forget these off the top of my head, but they're something like this:
Code:
sudo apt-get install -y build-essential kernel-package libncurses5-dev bzip2 abootimg
There might be more, idk. This should get you through the build. Let me know if there's anything else.
Next we'll make a directory and grab the sources.
Go to your main directory to store the android folder in (for tidiness sake), if you have a preference you can do this differently. If you're not sure what you're doing here, just go from where you are (should be your main dir):
Code:
mkdir android
cd ~/android
git clone https://github.com/Snepsts/kernel_e980.git
This might take a while... when it's done you should have a folder called "kernel_e980" in your android directory.
While we're downloading, go get the latest M build or the latest nightly of CyanogenMod: https://download.cyanogenmod.org/?device=e980
This will be useful later.
Now we go grab a toolchain. My favorite is this one: http://www.mediafire.com/?x7lgbeprpg8gn choose the cortex A-15 one. Untar it and move the folder wherever you like. I suggest the android folder to follow the rest of the guide.
Code:
cd ~/Downloads
tar -xvf arm-cortex_a15-linux-gnueabihf-linaro_4.7.4-2014.06-build_2014_09_13.tar.xz
Now move this folder through the GUI (Graphical User Interface), much easier than more commands imo.
Now rename the folder toolchain, just because it's easier.
Now we're ready to build. The username is whatever your Linux username is.
Code:
cd ~/android/kernel_e980
export ARCH=arm
export CROSS_COMPILE=/home/username/android/toolchain/bin/arm-cortex_A15-linux-gnueabihf-
make cyanogenmod_e980_defconfig
All ready to go
One last thing, before you make it, if you are a little more advanced and need to toggle something or do anything else, use:
Code:
make menuconfig
You probably don't need that.
The # means the amount of cores in your computer's processor +1. For example, my Linux virtual machine has 4 cores allocated to it, so I assign it -j5. Now to make the kernel:
Code:
make -j#
And watch the words flyyyyy.
If anything fails, double check you didn't mess up. Also, the current Github build is never guaranteed to succeed.
Once the build is completed, you should see something like:
zImage is created!
Or something. Now go to your Downloads and get the boot.img out of the CyanogenMod build whatever way you wish to.
We'll leave it in the Downloads folder for the sake of the guide:
Code:
cd ~/Downloads
abootimg -x boot.img
Now you should have a zImage, intrid.img, and a bootimg.cfg. Ignore the zImage, move the intrid.img and bootimg.cfg to the ~/android/kernel_e980/arch/arm/boot folder.
Now we finish the kernel:
Code:
cd ~/android/kernel_e980/arch/arm/boot
abootimg --create boot.img -f bootimg.cfg -k zImage -r intrid.img
Done! Your kernel will be the boot.img file.
Replace a current kernel.zip's boot.img with this one, you can use any of the E980Kernel+ .zip folders for this. Just remove the boot.img in that one then put yours in it. I always upload my kernel to Gdrive and then download it to my phone to flash. But whatever you wanna do from here is fine.
And now you have the latest version of E980Kernel+ Unofficial. Yay you!

About E980 Kernel+
In this post we will go over some of the things in this kernel and shed some light on what they do... Let me know if you have any information to contribute or anything else
Intelli-Plug
Intelli-Plug is developed and updated by Faux123.
Intelli-Plug is a hot plug replacement for Qualcomm's proprietary MP-Decision. MP-Decision essentially decides the final factor on clock speeds, when cores go offline, how long they go offline, and they generally manage your CPU. There is a lot of discussion over whether or not Qualcomm's solution to hot plugging is efficient or not. Intelli-Plug is an open-source and updated version of MP-Decision in which anybody can contribute to and improve. It uses different methods for arguably better performance and better battery life. The current version used is optimized for MSM-8960 chipsets (like ours). It is updated and even offers convenient profiles to optimize battery life, performance, balance the two, or do a little between each option. Some of the profiles allow an eco-mode like experience. Eco-mode is a depreciated feature of Intelli-Plug that turned a quad-core processor into a dual-core, effectively optimizing the processor to run like a dual-core and save more battery power. In order to toggle the profiles option without paying 5 dollars for the Faux Clock app, you may use a root explorer (like ES File Explorer), go to sys/module/intelli-plug/parameters/nr_run_profile_sel and input a number anywhere between 0-5.
I prefer this option ON and do not currently have a profile preference. In my experience it improves the overall device (performance/battery life) with no noticeable drawbacks.
Intelli-Thermal
Intelli-Thermal is developed and updated by Faux123.
Intelli-Thermal is a thermal replacement to Qualcomm's proprietary thermal solutions. It is open-source and anybody can contribute to it. It has optimized thermal performance and is arguably more efficient than stock thermal settings. In addition to being an open-source and updated module, Intelli-Thermal offers customization such as: personal selection of cores to throttle at a self-determined value, and a similar selection for cores to offline (minus core 0, since it must be online at all times). Intelli-Thermal allows you to set your own rules (do not set the limit too high) and thermal values are in Celsius.
I prefer this option ON, and set Frequency Throttle Limit to 70 C, Core Offline Limit to 65 C, enable all cores for Frequency Throttling Cores, and enable Cores 2 & 3 for Offline Cores. Rarely do I ever experience heat, and if so it is very minimal. The device may lag or get hot depending on your settings, so please be careful or mindful of what you set. This works better on some ROMs than others.
*** Personal Note: These two are of my favorites because they are optimized and make for a better experience with little to no performance drops. This is just my preference, and it can be chosen to follow as a guideline by your discretion. ***
Multi-Core Power Saving
This is a normal kernel feature.
Multi-Core Power Saving is a basic feature that, depending on the profile selection, groups tasks to a certain amount of cores. 0 is off, so the device runs as normal. 1 is on, and will try to group tasks into single cores or multiple cores at lower frequencies to save power, but will not force it. 2 is aggressive, and depending on the user, may find that this causes a little more lag as the phone really hates using any extra CPU juice for anything, processes may be clustered and slowed down from this, but battery life is also the best at 2.
I prefer this option set to 1, as it has no noticeable lag and seems to still optimize the battery a little more. This option varies from user to user.
Faux Sound Control
Faux Sound Control is developed and updated by Faux123.
Faux Sound Control is a custom feature that enables sound manipulation on the kernel level. This feature will allow you to modify the gain (Make sound louder at the potential cost of music quality or lower for ear protection) and other various settings from a kernel level. This is completely user preference and will vary from user to user.
Intelli-Demand CPU Governor
Intelli-Demand CPU Governor is yet another feature developed and updated by Faux123.
Intelli-Demand means Intelligent On Demand. On Demand is a kernel CPU Governor that comes as the stock setting for most phones. But it tends to be a little less than optimized and such results in sub-par battery life. Intelli-Demand is a tweaked version by Faux that will allow for similar performance and better battery life. It is also popular for gaming as when the GPU 3D load gets heavy it will perform like On Demand as not to interfere with game loads.
This is my current preferred CPU Gov as it has never given me problems and works like a charm.
I/O Scheduling
I/O Schedulers are different ways of controlling the input/output stream of information in with the memory of a phone. These generally do not vary too much in performance or battery-life but everybody seems to have a preferred one. I don't have a favorite and switch between noop, row, and zen from time to time again.
My only preferred setting here is setting the read-ahead buffer to 4096, as it increases speed and performance without any real hit to the battery.
TCP Congestion Control
I am not very well versed in TCP protocol or anything in the sort, but this basically controls how your phone interacts with Wifi/Data packets.
My preference (and, from what I've read, the general consensus) points to the Westwood TCP Congestion Controller. Never had any problems with it, too lazy to benchmark them.
I will add more later, and as I add features to the kernel, I will add explanations! Also, I plan on buying the Faux Clock app soon simply to figure out which profile is which (since the information is nowhere to be found) and then I'll return it and report the numbers back here. Also, whenever Cyanogen decides we're ready for CM12 official, the kernel will be ready for CM12 too. Please bear in mind that I hate updating and am not one with the Github (nor do I have time to learn about Github). Cheers! :good:

GOOD JOB:good::good::good:
And a little cpu overclock like 2ghz plzzzz ^^

Is it possible that you can create a kernel for F240?

Name... Hmmm

Hmmm... You posted the kernel for F240 to be compatible with E980 CM11 ROMs... right? If you can give me source for that I can try and add the same things to it as I am the e980. But I am by no means a dev or anything.

I hope I am able to deliver a kernel to you. By the way, what is the difference between F240 and E980/E988? I know E988 is international. Is F240 Viet or something? And what are hardware differences?

F240 is korean. I really don't know the exact difference between the E98x variants and the F240x. Maybe some kernel thingy.

Yes. VMware using Linux Mint 64-bit. My main machine is a Windows 7 with AMD FX-6350 (3.9 GHz) and 8 GB of RAM.
Here, read the guide mukwing gave me in this thread: http://forum.xda-developers.com/optimus-g-pro/general/making-cm11-0-kernel-e980-t2870820
That should be everything you need. Props to him he knows what he's doing!

I do believe there are some slight hardware differences which is what I read. I'm guessing the kernel you posted tells it to emulate an e980 somehow with the hardware. Maybe do something a little different to behave like e980. I don't really know though, that's just my guess. But yes I'll totally give it a shot if you can give me source.

Name it "Spartan" kernel or "Taco" kernel ?

Is the Taco kernel a reference to the flashaholic thread?
I like Spartan kernel though...
I was thinking of something like the "Ignis" kernel. Ignis is Latin for flame. Or maybe "Phoenix" kernel.

Knock on/double tap to wake please

Just tried to add some governors. Picked them right off of another kernel... I also copied and pasted the kconfig, makefile, and cpufreq.h files hoping that it would be the same... didn't work. Haha, guess I'll try typing in the config stuff myself and see where that gets me.

Adding features is the most headache things haha.
The commits from other device's kernel always not so compatible with e980 kernel.
Even commits from similar device's kernel like oppo n1 or G Pad 8.3 i still can't sucessfully incorporate them.
Without knowledge of programming, hard to find out what's wrong in the code.......
BTW, i have compiled a TWRP which can mount/read/write to F2FS formatted sdcard. But it lack the ability to format the sdcard to F2FS, need to do it in linux.(i am not sharing it because it still have chance of recovery bootloop)

Wow really? Damn I would have thought for sure HTC One kernels would have some similarity (Since we have identical processors).
Guess I'm learning C. I've actually made sense out of some of the programming already, but it's gonna be a ***** to get working. Thanks for the info though.

Good if you know programming language!
Waiting your kernel
But i will stay with stock lg for a while, haha.

Running this with acid and its running great, lost 2% between 11pm-6 in deepsleep:beer:

[PnP&Thermals tweak] Custom profiles for battery saving and/or better performance-v24

Addon was originally only available on Venom HUB but i decided to release it for everyone to use.Here is copy paste of description and changelogs from the HUB.I will update thread as i update it on HUB.
Also big thanks to @hamdir for testing my performance profile on various games, he will also post later hes review, pictures and comparisons to stock.
This addon is designed to save some extra battery, and reduce heat.Magic is done in 2 files:
1:Thermal-engine is tweaked in order to provide much better sustained performance and cooler phone, without big impact on performance.
2np file is another key component, its HTCs CPU/GPU/EMMC/MODEM and many more control engine.Here many tweaks where done, but gonna quickly list some of the important ones:
-Per app control, automatically suspends 2 BIG cores, and runs on 2 low power ones, it also limits the GPU speed to lowest.This will do only for some most commonly used apps, like Sense Prism, Nova launcher, Apex, other HTC apps, various chat programs(hangouts, facebook, messanger, whatsap etc), YouTube and some more.. as those apps dont require a lot power.
-Screen off is set to 2 low power cores for nice standby times
-Power saver is tweaked to actually save some power and not just lower screen brightness
-Extreme powersaver is also tweaked down to save even more power
-Input boost frequencies are also lowered (CPU ramps up moment you touch screen)
-And alot of other minor tweakups..
Also its recommended not to change anything CPU/GPU related in any other apps, like EX and just let this files do the job for you.
If for some reason you dont like this mod or have any problems with it, installer includes revert to stock option

Performance Profile
I've worked with @ivicask on optimizing gaming performance for the 1.80 base via the performance profile for this mod, in this post i will explain the gaming problem on stock HTC 10 and how this mod/performance profile solves it
by default HTC aggressively cripples the Snapdragon 820, not for the sake of thermals but for the sake of extending battery life, what happens is the following:
Stock CPU behavior on HTC ten (up to 1.80 base):
Starting with 33c battery temp CPU tasks will gradually migrate out of the big cluster, around 38c one of the two big Kryo cores (which enjoy higher clocks and bigger hardware cache) will be completely disabled, HTC smartly hides it in task migration rather than physically shutting down a big core
This means in CPU intensives games like Dead Effect 2 you will notice a sharp drop in performance/smoothness once the fourth core is killed, the game will drop from the 60fps range to 30fps, this behavior is noticeable in many games, if you are on complete stock you can only game at the full s820 speed if you are starting from a cool idle battery temp like 30c but then in about 5 minutes things will go downhill, considering that the HTC 10 idle state in average use is around 35c anyway you can see how most people probably start gaming on the 10 within the crippled state
Previously the only way to fix was to flash EX kernel with CPU migration hacked and already set by default to 60% limit, meaning EX kernel will refuse to let HTC 10 migrate tasks out of the fourth core under 40%, this is a good solution but you are forced to use EX kernel and not the stock kernel plus wait for the kernel source so that EX is updated whenever an OTA is rolled out, this mod will allow you to fix gaming on HTC 10 without touching the kernel plus it's thermally safe as its not a hack and will still gradually slow down the 10 to cool down, but it does so in a sane way
The performance profile in this mod was thoughtfully optimized by profiling the CPU usage in Dead Effect 2 (currently one of the heaviest games on the playstore) from 30c up to 45c, giving you enough time to actually enjoy this game at its full speed up to 30 minutes
The following tests will show you how the HTC 10 behaves in gaming when warm vs the performance profile, profiled using @ivicask tools and game benched in short sessions, the exact same level played from the same starting point to the same end at the same length of time, this level called "return to space gardens" is one of the heaviest sections in Dead Effect 2, at the end of this test you can see how performance drops to the ground because it meets a very dense and tough section in the game.
Stock kernel / PNP / thermals, Dead Effect 2 at 39c
The fourth big core is completely killed, GPU goes to 510mhz, small cluster drops to 1.3ghz, big cluster drops to 1.5ghz
As you can see on pure stock 1.80 base by 39c the games loses one of the big s820 cores and performance drops from 45fps range in this level to 30fps (which happens way too fast) also as seen in the yellow graph how performance stability is terrible, after 40c it will get even worse
here are the results from the same level using the performance profile of this mod
Performance Profile, Dead Effect 2 at 34c to 38c
full tasks are still running on all cores, GPU at 624mhz, small cluster still at 1.5ghz, big cluster drops to 1.5ghz
Performance Profile, Dead Effect 2 at 39c to 41c
both big cores drops to 80% task migration, GPU drops to 560mhz, small cluster still at 1.5ghz, big cluster still at 1.5ghz
Performance Profile, Dead Effect 2 at 42c to 43c
one big core sticks to 80% task migration the other big core drops further to 60%, GPU drops to 510mhz, small cluster still at 1.5ghz, big cluster still at 1.5ghz
Once the device gets warmer after 43c CPU migration will drop to 60% on both big cores with further reduction in GPU speed etc, but at this stage the HTC 10 will no longer heat up as fast and as you can see up to this point it was maintaining almost the same performance in this game; while keeping fairly high GPU clocks too; this is a much more subtle well thought performance degradation than HTC's stock blind brute crippling of the s820 which happens way too fast on low temps
This profile is so good actually HTC should probably copy it and imitate how it deals with default CPU migration, otherwise why are we buying an s820?

@ivicask
does it work differently from butterfly v11?
or say does it conflict with butterflyv11 if you have already loaded that profile and flash this zip?
thanks for another tweak made possible for Perfume devices

Completely different, it uses HTCs native engines to control everything, u can basically flash this on stock un-rooted phone
And doesn't require custom kernel, it should work immediately as new bases come out etc..

aah okay cool...does it conflict if i have already enabled butterflyv11 which disables pnq or its safe to flash while using that script

Half of this mod runs in PnP, if you disable it, your making this mod almost pointless.
Also, as i stated, this mod runs best standalone, its best not to use any other mods, or apps which change anything CPU /GPU related.
You can still flash EX kernel for example, i just dont recommend messing with any CPU/GPU related settings in it.

cool so this would conflict as butterflyv11 disables the pnp
would try this and see :highfive:

hey
great to see you released this for all on xda!
I have a question. since you wrote on the ex kernel thread that pnp config file is encrypted how come you can edit it?
or can you englighten me how i can just disable all Input and touch boosts from pnpmgr while keeping pnpmgr?
i think that would be the best for my script but i wasn´t able to do so.
i found no other way to stop the touchboost other than disabling pnpmgr completely.
maybe we can integrate my interactive values with your mod? if you are okay with this of course!
thanks

I cant give you much details on how i edit them, theres reason HTC encrypted them, if we spill it out, HTC would change encryption and everything very soon i suspect, so hope you understand why i wont share that part.
I can disable input boost for you, but im still not sure how your mod works along with PnP, as PnP constantly changes values dynamically, if you chmod values, than PnP constantly tries to change freqs and fails(may cause some problems).
What i can also do, is incorporate your changes directly into my mod, and make "ghostpeper" profile which would work directly in PnP, and people can choose and test which one works better for them and their daily usage.
EDIT:You could simple disable input boost by echoing 0(maybe chmod remove write permission after that so it cant change it) to
/sys/power/pnpmgr/touch_boost
/sys/power/pnpmgr/long_duration_touch_boost

I cant give you much details on how i edit them, theres reason HTC encrypted them, if we spill it out, HTC would change encryption and everything very soon i suspect, so hope you understand why i wont share that part.

yep i totally understand this. it would be however great if you could disable Input boost for me directly in the pnp binary.
i already tried to edit the files you mentioned in sys/power/pnpmgr. when i did this I got heavy lags. really heavy. i think something is conflicting there.
yeah the chmod trick worked before base 1.80. i would simply chmod the min freqs for big and Little Cluster and touchboost from pnpmgr disappeared magically. this trick is no longer working with the new base. that´s why i was forced to disable pnpmgr.
if you want to you can incorporate the Butterfly values for the interactive governor in your mod. I think Butterfly works far better on our 10, that´s why i just updated Butterfly for base 1.80.
does pnpmgr also edit the values for the interactive gov dynamically?
if you could make a pnpmgr config where touch/Input boost, Setting min/max freqs is disabled i´d be quite happy.

you may also just edit my script and comment out with a # or delete the line "stop pnpmgr" then the pnpmgr conflicting part will at least be removed.

Noice. Thanks for sharing

PnP controls everything u mentioned, all your butterfly/ghost scripts has, and about 10x times even more
I checked your script, you just echo to disable input boost, try chmod it after you disable it with denial permission so it cant be changed..
Should work, if not i can mode PnP for you, but above would be better solution for you..

Maybe others might ask too, sometimes I'm using it too for a systemless mod: do you plan to add it in as a systemless mod, if it is possible?

well, just related to OTAs, but that might be unimportant as you can flash back to original files, or restore no-RW mounted system image backups.
Or am i lagging behind, it's working to have a RW mounted system and do OTA updates? I don't follow that part much, my bad

I'm testing balanced option at the moment.
Also, i know I'm off topic, but in the end what's the recipe: what does and what doesn't affect androidPay. (I'm lagging behind again in this topic, just avoid modifying system partition in my kernel as it seemed to affect it at that time... as i don't use androidPay I didn't follow what exactly makes it unworking).

It checks alot of things, and its constantly updated, its simple must be done for security reasons..

Okay so I tried it with 444 permissions and it still lags. Should I try 000?
Would be great if you could make me a file with touchboost disabled and frequency changing disabled.

how to disable CPU cores

I want to know how to disable CPU cores to save power. It was possible on my nexus 5. but on my nexus 6p and now on my htc 10, I'm not sure if it's possible. I read that it's would need a kernel rewrite or something along those lines.
So does anyone know how to do this? I'm running latest LeeDroid ROM if that helps. thanks :good:

That's what I also wanted to know about the 10.
I had the mind before and there I could run with only one core, if not needed the other three cores. But if I needed power, the 4 cores are running.
It would be great, if there is an option in kernel settings to run all the cores only if they are really needed.
So the 10 is only a battery eater... Especially with sense roms I don't come through the day without charging.
On CM 14 or AOSP the battery is much more better, but with better core management it would be famous.

anyone got any info on this?

less cores doesn't mean better battery life, look at u11, "octa-core" and getting better battery life than 10 and anything else. it's een like if you have less cores, the cores which are online have to do all the work and might end up with locked max freq which will result in heat and more drain. so just keep the core control like it is and maybe just underclock

It is possible to disable cores with the custom kernel, and I believe force them to remain off at boot, but the HTC 10 uses a big/little cluster CPU setup and disabling cores isn't how you want to conserve power in my humble opinion.
The HTC 10 and some other modern devices uses BIG.little core ARM processor technology.
So the hardware and software is optimized to use all the cores to chase the best battery life and performance. I'm guessing that unless it's very specific usage scenarios, if you manage to force disable the cores with a custom kernel, you'll see both performance and battery life drop.
I would highly recommend installing a custom kernel, and tweaking the kernel settings while letting the hardware make full use of the BIG.little cluster system for efficiency. For high performance, I'd recommend one of the sense based kernel's that uses the HTC PnP Manager system. Something like Flar's ElementalX or TBalden's cleanslate kernel.
For battery efficiency, since you're really wanting to customize things for the best efficiency and battery life, try out the Helix kernel, by zeroinfinity. It's using a technology to optimize control of the processor based on "EAS" technology. EAS stands for "Energy Aware Scheduling" and zeroinfinity has written his "Helix Engine" to control the power profiles and thus power consumption of different apps, and you can customize the profiles to put any other apps you have in the profiles you want them.
This was a very basic and non technical summary, you can find tons of info on the kernels in the OP of each kernel thread. I would recommend making a backup with TWRP and trying both ElementalX and Helix kernels and seeing what works best in your usage scenario, before you start trying to force disable cores.
Here's a quick article I found on google, I'm at work and only briefly skimmed it, so no promises it's any good, but you can google BIG.little procs on Android mobile devices to find more imformation. https://community.arm.com/processors/b/blog/posts/ten-things-to-know-about-big-little

was a good read, thanks! based on the quote from below from that website sounds like the little cores can drive the most battery savings the most .... which is my goal.
The LITTLE cores can be implemented to target lower leakage and a more moderate performance point, independently from the physical implementation of the big cores that are often tuned for higher frequency.

Stock based sense roms. I just use it with regular rooted builds of leedroid or viper. It works with magisk and has been built to be fully compatible, however I use it for my normal modded system rooted sense based rom with supersu. I don't use or set up magisk, I'm still kind of old school.
But if you were to use magisk, @ZeroInfinity is running magisk as his daily since the last several builds, and I don't believe it's got any bugs or anything that doesn't work in the magisk build. One of the other team members @p50kombi knows a lot about magisk if you need to know anything further, I just have very limited magisk knowledge I'm general.

Great I also use supersu not magisk, probably same old school thing...also too tough getting things to play nice with magisk IMO. So for supersu do i just install v012 r1 systemless kernel and it should just work w/ leedoird? did you notice any functions on lee droid not working?
also do you underclock? recommend any kernel managers?

It's version 17, you'll download it from this post https://forum.xda-developers.com/showpost.php?p=73068312&postcount=1216 , sorry that link you had shouldn't be there, but systemless is the magisk version but now there's only one version, and the Aroma installer will let you choose the normal non-magisk version.
In the installer, there's a question that asks about installing custom scripts, I use the @ZeroInfinity script, the one from @roger81 and @TotallyAnxious are good too so you can't really go wrong, but I recommend starting with zero's, and you can reflash to experiment once you get going good with it. Rogers is great for battery life but his is a little more custom and extreme, which is why I'd start.
I use EXKM kernel manager, but I really recommend not changing many settings at first. Definitely leave the governor default with this kernel. I would run it like it comes out of the box, and see how your apps and battery life goes, and if you have apps causing a lot of drainage, maybe add them to the helix engine profiles before you start changing clock speeds.
You'll notice with EXKM the core frequencies reported in real time will look different from how it looks with a stock based kernel, but don't let that scare you.
My only other recommendation is if you use any other power saving apps like greenify or doze (I don't use any of them personally but some do) I would first get used to the kernel without them, so you kind of have a better idea of baseline.

Bonus points for being the least confusing AROMA installer I have used! and I used zero's as well. thanks for all your help! and one last thing.. isn't doze built into android nougat? or am I highly misinformed.

It is you're correct, but there's a lot of "super doze" and dozingest doze around" sort of mods and tweaks people use, it's the extra modified stuff I would avoid for now, until baseline is established. However once you get things ironed out, @RogerF81 (if I spelled that Right) has tons of good info on further tweaking. He once tweaked his battery life to something like 7 or 8 hours screen on time with the Helix EAS kernel. That's just showing off.
Glad you like the Aroma installer, it nearly killed the poor dev trying to get it set up when he first started implementing it, he still probably throws keyboards if I ask for a black theme lol.

*** Please click Thanks (Thumbs up icon) on my post here if you like my kernel and rate the thread 5 stars, then just use it and enjoy - if you want to send me a beer or two feel free - you don't have to use PayPal - Revolut and Amazon.com (USA) gift cards avoid fees. I like to hear from happy users I hope you are glad that you have the fastest phone in the world currently. The active cooling in this device is utilized to the extreme with MOD kernel, meanwhile your battery usage will be much improved at the same time. How? Well, that's all in the source code, free for all to fork it on GitHub and modify to your liking. Just don't forget to credit me and the many great devs that made the improvements possible... without them, there would be no MOD kernel. This is just a hobby of mine and I like to produce a nice product that all can enjoy. I'm also quite friendly and although I may tell you no I won't add that feature (such as network hacking tools), I won't hold anything against you for asking. I have not been compensated other than by some generous folks on my Telegram channel, so this whole project is basically self funded. Red Magic will not support it, unfortunately, but you can if you feel the improvements are worth it. I believe they are, but I come from a biased point of view as the sole developer for RM5G ***

Easy root method: https://forum.xda-developers.com/nu...nner-tutorial-unlock-bootloader-t4131585/amp/ although I suggest still using Magisk 20.4 for root.
Note: if you've already rooted and want to upgrade, people have had success saving the kernel as boot.img and TWRP as recovery.img in SmartPack, vbmeta skip as vbmeta.img and placing into the ROM update.zip using MT Manager (a root browser) and saving the updated file. Then do a Settings / System Update / click the 3 dots / local update and select your modified file. In fact I upgraded from 3.13 to 3.16 NA ROM without losing anything this way. Now for normal installation:
Custom kernels require root and Magisk to be installed. This is due to the signature not being signed by Red Magic (the company) itself. Following the above method you will still pass SafetyNet and most apps will work without trouble. If you have a specific app that detects root, well, Magisk Hide the app from Magisk Manager and see if that fixes it. You should also Hide Magisk Manager from various forms of detection (under Settings). Last case is to move the installation of Magisk under a random directory (which I have not had to do and all my banking apps still work), only if the root detection methods used by your app providers are more picky.
MOD KERNEL 1.4 STABLE:
RELEASE NOTES:
Block mode I/O has been changed to Multi-Queue from Single-Queue so your default scheduler is now MQ-deadline (credits to PappaSmurf, excellent kernel dev). You can choose between mq-deadline, kyber, and none in a kernel manager under I/O scheduler. From my benching with Androbench, it doesn't make much difference which one you use. Some have parameters you can tweak. None literally means no scheduler which is fine on an SSD, and has no overhead if you want to select it in a kernel manager. I always recommend SmartPack. To get settings to stick you Toggle "Apply on Boot" and it will go to what you've selected after 5-10 seconds on the next boot.
All debugging has been turned off completely on BBRv2 - thanks to PappaSmurf (I missed a few spots), and debug can't be turned back on from the userspace now. BBRv2 is selected as the default TCP algorithm which users have explained as a "no-lag" algorithm while gaming. It's just generally a fast algorithm all around. For me it works great, but you can still choose from many different algorithms in a kernel manager if you want to.
In SmartPack / Misc / TCP Congestion Algorithm, you have many choices: reno / bbr / bbr2 / bic / cdg / cubic / dctcp / westwood / highspeed / hybla / htcp / vegas / veno / scalable / lp / yeah / illinois. A SmartPack script is included below you can add in SmartPack to show the true TCP algorithm as it will always show Reno (a bug also shared by FK kernel manager). Below it's called Check_TCP.sh just go to SmartPack / Script Manager / Import / Check_TCP.sh. Afterwards, click Execute to see the active algorithm. If you set it on boot, this is the algorithm that will run, despite what the field says in Misc.
Battery is running very well on normal usage I'm getting around 7.5% active screen on drain over 7 hours and <0.7% screen off drain over 13 hours at 90hz screen setting. This is with actively using the phone for multiple "normal" purposes, reading emails, browsing websites with Chrome, reading news, streaming videos, etc. various shopping (Amazon/eBay) and tracking, Reddit feeds and live video, and other random "daily" tasks, up to 10 apps open at a time. Gaming of course will drain more, as will 144hz. I also have dark mode enabled in Settings. To get idle drain down I disabled 3 additional wakelocks that were causing high screen off drain, and so far I haven't seen an issue with blocking them. I also removed wakelocks that no longer exist since the Boeffla WL Blocker default list was created (it was quite old) so it now should be relevant for this device, with no interaction on the users part to disable anything via a kernel manager. Still, in SmartPack you will see a Wakelocks menu in case you install an app that causes idle drain to rise, this can be used to find and block wakelocks causing the problems. It can sort by wakeups and also by time. As it states though, you should be very careful what you disable. There can be unintended consequences and most wakelocks are not well documented as to what they actually control.
Dynamic Stune Boost is entirely removed from the kernel code now, as I didn't see any benefit from using it with this kernel.
Don't forget Dynamic Fsync is hidden under Misc in SmartPack which if you turn on will speed up your SQLite speeds. AnTuTu will penalize you for this, ignore it, your phone will be faster - but I leave it off by default. Androbench will show the true memory benefit. It is significant if an app does a lot of operations on databases. Journaling for the database is held in memory until the screen is off, then it is written. Although there is a chance of a data loss or corruption with this on if the device were to crash, it is safer than just turning off fsync. If you have any unstable apps, just leave it off - better to be safe. On a solid system though, you may notice better performance.
Also remember under SmartPack / GPU there is AdrenoBoost - it is set to low. You can alter to medium or high to get faster transfer between GPU frequencies, although it has worked great for me the way I use the phone. For you another setting may suit you better. Recall RedMagic OS only allows several frequencies which I spaced out as well as possible at 305mhz, 400mhz, 525mhz, 670mhz, 800mhz, and either 900 or 940mhz depending on the version you installed.
Overall I'm very satisfied with this kernel build and don't plan on adding or subtracting anything from it for the time being. It does what it should do, gives solid performance, and good battery life. My last score on AnTuTu setup with defaults 12GB/256GB was 682K which currently is still the top performing phone out there - running at 940mhz GPU. Not all phones can handle 940mhz so use 900mhz if yours cannot. If there are enough requests for an intermediate build (say 925mhz) I can add one later off the same code base. Also note in releases there are "gaming" builds that don't keep track of CPU times at each frequency, which was a request by users to remove any potential lag while gaming. I run the non gaming version, useful if you want to tweak battery usage, but nonetheless, both versions are there for you to use.
I'm on Telegram t.me/NubiaRedMagic5G_Mods as long as I have the phone. Which will be quite a while if Red Magic / Nubia decides to fix N41 5G in the USA.
Also note that all the features of this kernel (besides ones specifically added by me) are the creation of other developers whose contributions are all notated in the kernel source code. Some of the developers that have contributions here or helped me in some fashion: Resurrect88, DD3Boh, PappaSmurf, kdrag0n, Ayrton990, Flar2, Lord Boeffla, plus many more across the globe. Without them, I wouldn't be making any kernels! And I'm sure there are many other devs I've forgotten to mention, I thank all you guys for your help and support.

8th Release:
MOD KERNEL 1.35-BBRv2 STABLE:
RELEASE NOTES:
This is an intermediate release - I realized that the prior release was draining far more battery than it should, and I found the source was debug related code in BBRv2 from Google. So this is the updated kernel that gives you battery life like before this TCP algorithm was added.
CONFIG_CPU_FREQ_TIMES=y has also been added so you can see in a kernel manager how much time is spent in each mhz block for each set of processors. This can be useful if you set in a kernel manager (like SmartPack) a minimum CPU mhz to see how much time is actually spent at each level.
The code base also has Dynamic Stune Boost, but I haven't had time to optimize it for the device, so it's just on default settings. So there are 2 versions of this 1.35-bbr2 release. At some point it will be enabled as part of a regular release (some 17 commits squashed together into 1, Stune Assist was causing issues so I turned it off). The main idea of that set of code additions is to run the device at lower frequencies, saving battery, while still achieving the same performance level to the user of the phone. If you want to try different options for it in SmartPack or FK Kernel Manager you can.

7th Release:
MOD KERNEL 1.3-BBRv2 STABLE:
RELEASE NOTES:
Added the 31+ commits for BBRv2 from Google. Squashed the commits down to 6 by author from Google (for easy code maintenance). It's said to be the best TCP (internet congestion) algorithm so this sets it by default. You can still select from the others added in 1.3, as mentioned only EX Kernel manager properly shows them. But SmartPack if you choose the one you want under Misc, then click Apply on Boot, it actually will load the TCP algo you selected. It's just a visual defect. I also made a script for SmartPack uploaded to show you the TCP algo that's selected in my repo you can install so you can verify for yourself. Give it 10 seconds (default on boot setting) before you check.

6th Release:
MOD KERNEL 1.3 STABLE
RELEASE NOTES:
All this release adds is TCP congestion algorithms. The only kernel manager which correctly shows the algo set correctly is EX Kernel Manager. Using SmartPack or FK Kernel Manager will tell you that you're always on Reno, when in fact, you aren't. I'm not quite sure if this is bug related to 865 kernels as a fellow dev had the same experience (on an Op8 Pro). Now the default is set to BBR. Why? No reason specifically, although it is one of the better algorithms for internet usage. You can easily change in any kernel manager and set on boot which one you'd like to use (see above RELEASE NOTES if using SmartPack). But this gives you plenty of options:
BBR, BIC, CDG, CUBIC, DCTCP, WESTWOOD, HSTCP, HYBLA, HTCP, VEGAS, RENO, VENO, SCALABLE, LP, YEAH, ILLINOIS
You can Google the benefits of each and pick what you like. Or just leave it alone. The prime idea of MOD kernel is that you don't need to adjust anything it just works optimally without any intervention. Read the release notes for prior features that have been added. There are many just not summarized in a single place at the moment. All the optimization has been done for Red Magic OS.

5th Release:
MOD KERNEL 1.25BETA
RELEASE NOTES:
This release is mostly about battery savings. I'm averaging around 6.5% active drain on normal tasks with this version (90hz setting), and around 0.5% screen off drain. A big improvement over the stock kernel. So I ended up with about 13 hours SOT + 24 hours screen off on 1 charge! See the picture, I stopped at 11% left. Now I didn't say anything about gaming. If you want to game and have power saving benefits, don't enable any of the built in boosting modes in the game launcher - the Red Magic OS will override everything. Let the kernel do the work for you. And if you're seeing any graphics lag, go into SmartPack kernel manager (free) and go under GPU, Adreno Boost is enabled on low, you can set it to medium or high. That will increase the speed at which the GPU throttles up and down.
1) Switch to the Energy Model for CPUs: Several subsystems (thermal and/or the task scheduler for example) can leverage information about the energy consumed by CPUs to make smarter decisions. This config option enables the framework from which subsystems can access the energy models.
2) Added CPUMASKS for the Little, Big, and Prime cores from Sultan Alsawaf Sultan: SultanXDA, prime added by Danny Lin: kdrag0n.
3) Added kernel control of the minimum frequencies for the little and big clusters by Danny Lin kdrag0n. They are set to run at their minimum running frequencies when idle 691mhz (little) and 710mhz (big) which results in nice power savings when web browsing or just under low load in general. Prime cluster min is not set as it makes the CPU scheduler function poorly.
4) Added AdrenoBoost by Aaron Segaert: Flar2, with all its changes squashed into 1 commit. Defaults to low setting. As mentioned before, you can change in SmartPack, and set on boot if you need a higher value than low: https://github.com/SmartPack/SmartPack-Kernel-Manager/releases
5) Uploaded the various GPU OC files to the repo, It still will just build off the default one, but they are here to be complete. 940mhz version again is posted, Building direct from the repo will give you 900mhz max GPU.

4th Release:
MOD KERNEL 1.2 BETA
RELEASE NOTES: (Note a 940mhz GPU clock edition is available, if you want to try it, a few of us have had good results on it. Likely the max an 865 GPU can run. You'll sacrifice the power savings, however):
1) Enable Power-efficient workqueues by default, add a toggle that can turn this off via a kernel manager (under CPU in SmartPack). Enabling this makes the per-cpu workqueues which were observed to contribute significantly to power consumption unbound, leading to measurably lower power usage at the cost of small performance overhead. Have also added many other power saving features to the defconfig. The phone is a beast, power savings is a good thing to implement.
2) Update the LZ4 decompressor algorithm with a much faster variant for the ZRAM swap, now version 1.8.3-9 credits Gao Xiang [email protected] and many others (check commits). Speed improvement below (should help on 8GB devices):
Compressor name Compress. Decompress. Compr. size Ratio Filename
lz4hc 1.7.3 -9 12 MB/s 653 MB/s 42203253 42.20 enwik8
lz4hc 1.8.3 -9 11 MB/s 965 MB/s 42203094 42.20 enwik8
3) Default scheduler is set to SQ deadline. Should see minimal improvements in speed until I get a MQ variant working. On the task list ahead.

940mhz GPU release here, it's still 1.2BETA, just with the max clock a few of us have been able to use. That doesn't mean your device can for sure handle it, but give it a try if you'd like! Note the power savings will likely not be there vs the other release at 900mhz:

3rd Release:
1.15BETA: https://github.com/mrslezak/NX659J_Q_kernel/releases/tag/1.15BETA
This is a HEAVILY updated release of the MOD kernel 1.10BETA - I realized the phone's software will allow 6 frequency clocks, although 1 did not have a regulator defined (now patched). NOW I VERY HIGHLY suggest installing SmartPack Kernel manager. It will give you insights into the kernel and how it's performing and it's free. It also will let you adjust added options now in the kernel. Just root your phone and flash from TWRP. If you haven't already installed Magisk, then install that too. There's a guide I posted on XDA about that. Use the experimental method there is no reason to unlock your bootloader. https://forum.xda-developers.com/nu...how-to-unlock-bootloader-redmagic-5g-t4081743
RELEASE NOTES:
1) Bugfix: there was 1 missing 800mhz GPU frequency regulator clock on the prior version. This has been set to TURBO, 1 level under the 900mhz regulator of TURBO_L1.
2) Boeffla WakeLock blocker (v1.10 + tweaks) has been added to reduce battery drain when the phone is not being used, using the latest version and all patches. A default block list is included. You can access in SmartPack Kernel Manager under the new menu that will appear "Wakelocks" - especially investigate if your phone has high idle drain, you can experiment with blocking other wakelocks (which don't allow your phone to sleep). Or you can leave as is. I get just under 1% drain (screen off) and the phone sleeps quite often with this version. Take a look at the screen shot! That's just normal phone usage, not gaming.
3) All debug entries (except those required) have been stripped completely out of the kernel. This results in less wasteful debug information being generated.
4) The default algorithm for ZRAM has been changed from LZO (high compression, but slow) to LZ4 (slightly less compression, but fast). LZ4 algo was added. It still defaults to 4GB.
5) Dynamic Fsync has been added to the kernel as well. This patch allows journal entries to be written only when the screen is off. I.e. they are cached and written afterwards. This increases database performance. It is disabled by default so in SmartPack Kernel manager, if you'd like to turn it on, go under Misc, select Dynamic Fysnc, and select apply on boot. There is always a risk of data loss when delaying writes, although I've personally never have had issues - it only happens if the phone crashes, and mine has never crashed on this kernel. This won't normally increase your benchmark scores (except AndroBench), it increases SQLite database access speed. Up to you to use or not, works fine on my device.
6) Here are the updated frequencies (note there is 1 more). Will have to wait for AOSP before I can add back more. Note the 670MHz is likely the 865+ max frequency per the release notes today on the device (which I assumed by the source code anyhow pre-announcement): 900MHz / 800MHz / 670MHz / 525MHz / 400MHz / 305MHz
AS ALWAYS, USE AT YOUR OWN RISK!!!

Initial Release:

Second release - gets over the "reset to 490mhz" bug caused by the system software, at the expense of reducing frequencies to 6 total:

Newest release -> will be posted on the top from now on.

And note the AnTuTu benchmark is just a first run after installing. 670K is likely a record on any 865 phone. The last bench turning off 4GB ZRAM (12gb/256gb device) I got 673K. AnTuTu doesn't equal performance, but if you've benched you'll see this is an insane improvement over the stock kernel. Only when the demand is there will it scale up to 900mhz. I've been using for a while now and notice no difference in battery life. The Adreno driver is very good at handling extra clock frequencies efficiently without modification (despite an "Adreno Boost" that is often added to kernels). The gamers using the kernel are making statements that they couldn't imagine the game play any better than it already was, but now it's even smoother.
Unfortunately the way the Nubia software behaves, it auto-resets to power level 5 (which was 490mhz) on the 1.0BETA on boot and also after boosting the frequencies up. I tried every possible way to bypass this but eventually just gave in and removed frequencies. So the BETA1.10 and above have less frequencies but will always revert to 305mhz, the base minimum frequency of the device. Hopefully once we have AOSP ready I can add more.

Nice work. Do you notice any benefits to OCing the GPU like that? I don't think there are many games that would benefit atm.

This is amazing !!! :laugh:

Is this going to work on all roms like CN, NA or EU Roms? Im currently running NA 3.11 flash from CN rom with root and twrp

We have people using it on CN Global and NA versions no problem at all. Works fine on every model.

Kernel is fully functional no issues at all.
CN Rom to NA Rom v3.11
305mhz min to 900mhz max confirmed and using smart pack to control the frequency
Thank you for this hopefully there is more development i really appreciate ur effort

Kernel building is just a hobby of mine, I was posting a minimal kernel to get some more kernel developers on board to hopefully add more features. I usually add Boeffla Wakelock Blocker and Dynamic Fsync and call it a basic kernel. The last super kernel I made took way too long, and I don't have that kind of time anymore - boost functions and underclocking to balance out the battery life and such. Development work doesn't pay anything, I didn't get the phone free, all my donations go to other developers. And I have a full time job and family. But if anyone wants to port over my MOD Kernel Q 1.5 Mi9 features, well that would be a super kernel. It's just really, really time consuming, time I don't have at the moment. And the merging of source has to be EXACT or you end up with a really slow phone rather one that balances underclocking, boost, and overclocking.

All the gamers using the kernel are reporting that the games run smoother than before, which no one thought was possible. It is already a flagship device. But the GPU OC with the Adreno driver scales when needed up to the frequencies that it has in the table and has no issue on 670, 800, and 900mhz reported so far. There are gamers on NA, Global, and CN ROMs, with no bugs reported. No issues and everything works properly. I have tested myself and although I'm not a gamer, all the functions work as they should. It still connects via Bluetooth, it still takes photos and videos, etc. There is no lag whatsoever. Overall I think the frequencies are ideal for this device with it's advanced active cooling system. Other devices however, with passive cooling, are unlikely to handle the increased GPU clocks.

I found an unusual bug where the GPU Minimum Frequency will reset on its own to 490mhz even if i set the minimum frequency to 305mhz im using smart pack kernel manager that you provided and cool tool btw to monitor the gpu frequency.
I also set the battery optimization to off on smart pack so it wont turn off itself.
This also happens when i played games that actually boost to 800 to 900mhz then after i close the game it sets back the minimum frequency to 490mhz so i have to set it again to 305mhz on the kernel manager to save more battery and lower the temps.
I also notice it sets back to 490mhz minimum frequency by just watching youtube videos so i have to set it back to 305mhz again. I tried different kernel manager too like Franco Kernel Manager and Kernel Audiator and still doesnt fix the issue
I think this was a minor bug for sure
I never touch the GPU governor btw
Performance was super nice thou i scored 645k on antutu on my first run but for now im going back to stock and gonna wait for your next update

What to do to root the phone without breaking the fingerprint please. I read the article publish nothing understood someone can explain to me step by step. I am an amateur I never root a phone. I have cn 2.55 16gb.

I don't have the same issue - I just tried to recreate it by watching a YouTube video and I went back to SmartPack and it still shows 305MHz GPU frequency. Although I'm using the debloated / optimized ROM I created Black Magic 5G which has everything setup properly, Nubia apps frozen, everything moved to 3rd party apps. NETFLIX patched to 4K HDR10, YouTube Vanced, a ton of root utilities, AdAway ad blocker, etc. You can find it on the Telegram channel (I'm using the NA/Global version of Black Magic 5G). Then I watched Netflix, still at 305mhz. As I have no idea how you've setup your phone, I just can't recreate it.

Yeah maybe because you modified the rom.
Im currently running Flash Global V3.11 when i tested your kernel no modification made im just rooted with TWRP Installed and i posted this kernel on red magic 5g group on facebook and 3 of us having the same issues as well.
Im gonna try it again on V3.13
UPDATE:
still returning to 490mhz as minimum frequency after gaming and after watching one youtube clip
kinda sad hopefully you can fix this bug on the global rom that nubia provided if you have the time, great kernel for gaming because of the 900mhz boost and the phone can sustain this boost because of the active fan

Why don't I have a roughly similar score?

Is it possible to overclock the CPU as well? They officially release the specs sheet of ROG Phone 3 it has overclocked CPU (3.091ghz) and an overclocked GPU. I know this phone can keep up with those clocks because of the cooling system but the problem is the battery life. But still, its worth it.

I believe Qualcomm blocked overclocking of CPUs quite a while ago from SD845. Only GPUs can be overclocked.
Though I don't know if devs have gotten tools to get around it.

The 490 bug looks like it's related to the gaming mode APK resetting the min frequency. I can't decompile or recompile APKs so I don't have a way to get around the system reverting to 490 without removing 3 other frequencies. It seems hard-coded in the app that it only expects to see 5 frequencies so to have all working properly, 3 need to be removed. This is in contrast to what my buddy dev on the Op8 Pro can do, but this device is designed differently in how it boots and custom apps that increase frequency clocks. If any devs are good with APKs it's a very simple function call that sets the minimum GPU frequency. The only odd thing I see is that the minimum power level stays at 8 (minimum) which corresponds to the lowest clock speed. That number doesn't change in a kernel manager when the min GPU clock reverts to 490.
I'm off on vacation not near a PC but will try to come up with a stock # of clock frequencies that still scrolls smoothly between them and the Adreno GPU driver. May take a few tries but it's quite easy to modify. I already think 180mhz is too low from using it, it's more of a sleep frequency some suggested going this low but I think the phone design is for 300+. I prefer to use more clocks for better throttling but have to work with what we are given and do the best inside those boundaries.
No you can't raise CPU clocks on 865 devices that ROG device is supposedly using the 865+ or whatever the mid device is named between the 865 and 875. They have blocked CPU OC hardware wise for some time now.

Qualcomm's Meizu’s CMO Wan Zhiqiang recently commented on Weibo saying that there won’t be a Snapdragon 865 Plus this year.
We will see!

No 865+ this year..
Trust me whatever they call it it's already defined in the source code as a second GPU bin clock for another device ID. So maybe it won't be called an 865+ but there is some device between the 865 and 875 coming out. I have OEM confirmation as well this device exists the name isn't important. I can tell you the top GPU frequency is 670mhz that's it, vs. the 587mhz default on the 865. Still the 865 handles 900mhz GPU no problem the only benefit would be higher CPU clocks. And an extra GPU clock. Which I'll attempt to spoof next time I get near a PC.

Is it possible to overclock the memory clock too? I assumed that 900mhz is the core clock.

You're right, that makes sense.
I'm glad they are making a refreshed chip.
On another note, do you think we will see an overclocking tool in the future?
Possibly with a custom ROM?
