This should work on all CM/AOSP based roms, stock support has been re-implemented. Use of UKM for synapse to work (at all) requires init.d. Most stock based roms should have this, but a rooted OTA won't unless you added it (lots of methods, Google around a bit).
Hi Everybody. Since I haven't seen anyone making custom kernels yet for us for the 39A base, I decided I'd try pulling in some features that I use on a regular basis into the kernel source.
Most everything in this is pulled from ( in no particular order ) Faux123, Showp1984, flar2, Renderbroken, Dorimanx, Jackpotclavin, xdabbeb, Rashed, Myfluxi, franciscofranco, tsunamical and other sources. So, all credit goes to them.
I've switched over to Synapse/UKM for this, seems that most everything works properly in it. I've changed francosound slightly, so you'll need to use the modified UKM linked at the end of this post, then install synapse from the playstore.
Features:
Added Intelliactive, Intellimm, Smartmax, ElemantalX, Bacon, Imupulse, ZZmove, and Yankactive governors.
Added Intelliplug (Set as default through
Added FrancoFranciso's sound driver. (Mic, Headphone, Speaker, Camera Mic volume control)
Added 389Mhz GPU step
Enabled Extra I/O schedulers and TCP congestion methods
Enabled Kernel Same Page Merging.
All builds are permissive.
Added Bricked Hotplug
Added Bricked Thermal
Added UserSpace CPU Frequency Voltage Table
MsM Limiter from NeoBuddy89
FastCharge from Dorimanx
Added a post boot script that will provide tweaked defaults (basically what I use minus undervolting)
Exposed PVS and SPEED bin values to Synapse for informational purposes.
Misc Tweaks/Optimizations/Battery Saving Optimizations
Screen turn on bug fixed courtesy of JackPotClavin
Stock Builds should work correctly now. (bluetooth and back led issues should be corrected)
F2FS support
Known Issues:
None
I'll work on things as I get time, but I'm not promising anything as this is simply a kernel that I'm making for the features I typically use. A lot of code has changed in the new kernel source making it hard to import features, so it's slow going. Also, sorry for the kernel name, I didn't have anything creative at the time.
Source: Github
CONVERTING DATA TO F2FS WILL WIPE YOUR SDCARD DATA AS WELL. Ensure that you have a backup of everything on your computer before doing so as this is unrecoverable. For R3, with F2FS you'll want this repacked TWRP. It has this kernel packed into it, with better f2fs support libraries (thanks XDABBEB). Also, be aware that encryption is not currently enabled with F2FS partitions in the way that I have it configured.

Modified UKM: 3.8.1-Mod6-Fustercluck (Source) - Apb_Axel's Original Thread Huge Thanks to him for his work making UKM.
Remember to hit the "Thanks" if you're enjoying this kernel.

For anyone who wants to build from this, I've included the toolchain , ramdisk, and a build script in the github repo. As long you have a build environment setup, you should get a flashable zip in the zips folder just from running the included build.sh script.
*edit*
I've removed the toolchain and all git references to it. It was causing the repo to be far larger than it needed to be. It's easy enough to find a toolchain (I've been using sabermod) and place it in the directory the build script expects. The one I use is Sabermod 5.1
Edit:
Development will be halted as my g2 digitizer is failing and I'm likely to upgrade to a nexus 6.

This kernel is SORELY needed. Constantly torn between being on 5.1 vs. 5.0.2 or JB vs. KK aboot, etc. And now I finally feel like I can have it all. Thank you! Working great so far on Euphoria ROM.
Only suggestion would be making the kernel default to be selinux permissive, especially with Google pulling an Apple and banning many of the selinux modifying apps from the playstore.
Thanks again!

Yeah, I'll put up a build that's permissive. But d-h.st is being a pain right now and not actually letting me upload.
I was going to write up a post about the dangers of permissive kernels, then saw avc denials for an init.d script, netmgrd, sensors.qcom, and busybox in my dmesg (of course I was going to check before I posted)...
Just remember though enforcing stops things from running out of context. It's a security features and that's why google's removing the apps that let you change it. Permissive lets everything do whatever it wants and just logs that it should have been denied (dmesg | grep "avc"). So essentially, it's like installing an antivirus on your computer then disabling it but letting the system tray icon give you a warm fuzzy. Antivirus is a bad analog because it's really more like user policies, but you get the point.
*edit*
for now, I'll just attach the permissive build to this post. I'll need to wait till d-h.st gets it together. Maybe, I'll look for a better file server.

Does this have Bacon or smartass? If not is it a possibility in the future?

Yeah, I'll work on grabbing them. I'll need to find a good version of bacon from somewhere though that hasn't been too tweaked/modified.
Also, I'm moving to androidfilehost. for hosting. d-h.st just wasn't working out. I'd like to find somewhere that gives ftp access so that I could just upload builds at the end of my build script, but I guess that's not a huge deal.
Anyway, the new folder will be: https://www.androidfilehost.com/?w=files&flid=29865
The build numbers are just there to help me keep track of what file I'm on and need to flash for testing, don't let them get you confused if there are missing numbers in that folder... they just weren't worth uploading, or the build failed.
Also, how is the fauxsound stuff working out for everyone? I feel like it's pickup up the register values wrong or something... I'm not quite sure yet. But the sound seems too quiet on the low-end, but at least boosting the high-end works.

Just gonna throw this out there since you arm like a hands on dev, what are your personal settings? Default? I'm super excited for this kernel but after using dori for a while, the feature creep became somewhat mind boggling.

I'm not really comfortable being called a dev, I have some understanding of what's going on but the real devs are the guys that I gave credit to in the OP. Really, I'm just pulling in their work and making little changes here and there to make it work.
Personally, I run intelliactive with intelliplug and westwood with zen set to 1024 (why I added those) but I don't tweak the settings. I've never really seen a reason to, the governors are pretty smart. Of course, if you know what you're doing you can always fine tune them some based on your personal use types.
As far as feature creep... Read up on the different things. Figure out what works for you, ignore the rest. Really, it's just there because ya know... different strokes for different folks.

That's exactly the answer I was looking for. Thank you!

New build (30) up, sorry for the number jump... took a good few build tries getting the governors to play nice.
This added Smartmax, ZZmove, and Yankactive.
Should also fix GPU freq reporting. Previously, it wasn't reading correctly.
*edit*
Seems some of these new governors don't play so nice under use, at least not for me. They govern, but it seems like my device is locking up or not turning the screen back on with them. Looks like they need a little polishing.

I am using Intelliactive as well, on Euphoria v1.1, which sticks, but Intelliplug does not.
Also, only Smartmax worked for me with the new governors, but the others rebooted my phone almost instantaneously.

Thanks for the feedback.
Yeah, I ended up just removing zzmove and yankactive for now but added bacon and impulse. I'm not sure what exactly is going on with those two, but they kept trying to switch the devfreq governor to one that I shouldn't have included to begin with, the calls it used I don't think are present anymore. Which could very well be the reason they were freezing.
The intelliplug is a little weird too depending on which tuning app you use. Synapse lets it stick, but never shows that mpdecision turned off. Kernel auditor shows both on, but trickstermod shows that it correctly. ...kinda weird and I don't trust the apps to be honest. The sysfs values for intelliplug is toggling and the mpdecision binary stops running (at least with trickster) so those apps could be doing any number of things wrong.

Thanks for continuing to tinker and your analysis. I just did a reboot and checked Kernel Adiutor and even the governor is not sticking. I will try Trickster, as I am used to that app, but agree with you, each can be doing something wonky with your kernel.

Phone feels faster after this kernel, loving that. As for synapse, it tells me no UCI support and that's the end of that. I found kernel adiutor and it seems to be alright. The headphone amp doesn't seem to want to change which is annoying since I really want that. I think I'm just gonna clean flash the next euphoria build. Congrats on the first kernel for 39a roms.

Yeah, the headphone poweramp is buggy. I still think it's an issue because I pulled Shamu's (Nexus 6) fauxsound. But you still get the volume boost with the headphone volume choice. For synapse to work at all on most kernels now you need to download and flash teh UKM script.
But yeah, there are still things that are buggy. Which is why I'm leaving this labeled as an alpha for awhile.
I've been working on governors most of the day, I'll reply here when I get an update posted.

Yeah, FauxSound thru the speakers just cuts in and out, mostly out.

That's odd, I listened to my phone through the speakers for a good few hours yesterday moving my inlaws. Didn't notice any cutting in and out.
Can you tell me what values you have in: /sys/kernel/sound_countrol_3/gpl_speaker_gain ?
I have "2 2" at the moment, but I have my speakers down... typically I've been holding them at "5 5"
Also, are you using anything like viper? Are you using this on a CM12.1 based 39a rom?
*edit*
Also, New build up. https://www.androidfilehost.com/?fid=96039337900114170
Removed a few of the unused Devfreq governors (for gpu).
Added ElementalX, Bacon, and Impulse Governors. Removed ZZmove and Yankactive
Changed some compile flags, might give better performance.
Misc tweaks.

Another Build: https://www.androidfilehost.com/?fid=96039337900114287
Added in Bricked Hotplug and Bricked Thermal.
I may be a bit slower on adding things and building the next couple days... weekends over.

No different, I just prefer bricked thermal over the normal one. I usually set the temp limits 2 or 3 below the defaults.
I'm just trying to get the features added so that people have options. I sent faux a message, I don't really expect a reply because I'm sure he's pretty busy.... But figure is give it a shot to see if he can help with the faux sound issues.
Once that's worked out, everything should be fairly stable. Then I can try to figure out what's up with some of the tuner apps not recognizing things correctly.

CPU load with custom CM13 kernels

Guys.. With every Android since the 2.x, you could activate the "Developers Options" and activate an option called "Show CPU usage".
"The numbers show the average load of the CPU in different time intervals. From left to right: last minute/last five minutes/last fifteen minutes"
My doubt: When I install any CM13 ROM (now I'm with Exodus) on my S5 (G900M), the load, after some minutes, are always near 10. Now I'm staring at it, with many apps installed (whatsapp, facebook, uber, maps, messenger, firefox, mx player, es file explorer, foursquare, traceroute, wifi analyzer, gmail, imo, os monitor, tinder, fing, poweramp, mindroid, remote desktop, 99, youtube, andsmb, diskusage, soundhound, photos, dropbox, goseek, instagram, juicessh, google now, picsplay, speedtest, skype, swiftkey, stabilitytest... just to name some...) and it's 11.32 / 14.37 / 23.11
Now the problem: whenever I install Boeffla Kernel or CrazyKernel, the load is ALWAYS higher.. always nearing 20. With default options, or trying to tweak the cpu options in both kernels.. and the bigger problem is that I SENSE that. The phone seems to RUNS SLOWER.
ps: If you LOCK your device (or let it lock by the timeout), this "load" value will raise because the cpu will also run slower.. it doesn't mean it's working more, just that more work is queued to the cpu, as it doesn't NEED to work on it (because it's locked/screen turned off, etc)

Hi,
I guess everyone will have that. So the poll is quite useless.
The reason for it, as I tracked down:
Two governors (intellimm and slim) are adding overhead to the system, even when they are not used.
Why? I do not know, as I am not the developer of these governors.
But for a test, I removed them from beta11 and compiled it as a beta11test1 version, attached here.
Let me know if removal of these governors lowers the cpu utilization for you down to stock levels almost.

Wow that was fast. I'm testing right now and yes, the CPU load is *finally* down to ~11 like it were with vanilla CM13 kernel (which I think is what Exodus uses).
Still I get a little lag here and there mostly when "loading" stuff (like when clicking in a group chat on whatsapp, which needs to open a huge .db to display the history.. I think).....
But nice work.. I wonder what more could be optimized.. it's strange to a vanilla kernel be snappier than a custom .. given the experience you have..
Thanks

I am not sure vanilla stock kernel is more snappy. I feel it is the other way round personally. But this is about expectations and perception. Also it is about what is important for one. A custom kernel gives you many other goodies that might of course compromise in other areas. Nothing is for free.
And I personally prefer some other features over pure performance.
But well, that's it. I will not do more, having in mind the s5 kernel is only my #5 kernel in terms of priority. Sorry.

Elite Performance

I have spent crazy amount of time tuning my Galaxy S5 G900F running the latest CM13 release with the stable Boeffla kernel and I finally think I totally mastered the performance level at perfect stability without any overheating issues or crashes.
I just got a splendid 64676 score from the latest antutu benchmark! That is way higher than any old 32bit Snapdragon 801 device has ever gotten and the RAM and I/O performance is just ridiculous that beats much newer and more expensive phones.
This is enabling me to play VP9 videos at 1080p completely smooth without any drop in quality or FPS. The best part is that the phone newer overheats or lags. I can run some serious multitasking and download at least 8 files simultaneously from 8 multi-threads at blistering speed including complex merging, decoding and encoding procedures just fine and using the phone for common tasks in the meantime.
For those who want to be able to shoot 60 FPS 720p videos get the Snap Camera HDR app and with correct settings that will be quite possible. Just let me know if you need instructions how to set it up properly.
I included a screen shot of the benchmark score.

i confirm - cm 13 last nightly releases really fast and stable, i try boeffla now
i think it the best performance rom on s5 now

Thanks, I got a s5 a few weeks and didnt know which rom choice. I'll try cm13
Enviado de meu SM-G900M usando Tapatalk

Reliability test complete without any notable problems. Ran another antutu test and got 64k again. So now I'll post my setup.

I have a very clean setup of CM13 and chose the Pico Gapps version and also have xposed. So I only have the most necessary apps that I want to use to reduce all weight on the system. I also use the recent apps task killer when ever I'm done with current tasks to free the ram for next use. I hate the low memory killer because it stop certain background processes like arkTube so I put everything down to 5 and use the task killer myself.

I'd rather go with the latest release because there are still few glitches left like soft reboot does not work properly. Use stable kernel for release and beta for nightly.

New high score record for the S5 with the 3.3 kernel running CM13. Going to try CM14.1 next.

Please help I'm a noon
OK so I just read your thread and I wanted to ask a few questions but before that let me explain to you that I'm very new to costum kernel and costum rom stuff. First question what's your best recommendation for the fastest stable rom (currently updated). Second question you said you will go too cm14.1? Will that be a faster and better than the one you metioned in this thread? Third question if this is the best tweak for the s5 may you provide links to the programs you used to do this and possibly a tutorial if not it's cool I'm usually fine doing this kind of things on my own, a little guidance will be helpful though ? Sorry for being a noob but could you please help me out I just rooted my s5 (SM-G900T) and download set cpu but I've read that it won't work unless you have costum rom/kernel and thats why I'm asking for help. Please and thank you.

Great job! Do you use new Adreno drivers or rather stick to the old ones? And, do you have your camera working? I'm trying to replicate your setup and the only thing that bothers me is the camera error....

And how about battery life? That OC to 2.8Ghz looks like a battery killler (to me at least)

I made sure the setup is totally interactive. It only uses a lot of power when under heavy load. The hardware goes in deep sleep when the phone is not in use.

As you can see in attached screenshots, one third of of the device's on time is in deep sleep. Input boost is on at highest settings and CPU/GPU locked at max frequency when under load so responsibility is quite good. The main power drainer is the screen at high brightness or heavy multi downloads or gaming mostly.

The screenshots. When it goes under heavy load it throttles down and up various frequencies to protect it from overheating. So let's say I download 500 files, 8 files simultaneously by an 8 multi thread method at above 120 Mbits the CPU goes under heavy load, a lot more frequencies would be used because of the throttling.

Here is a link to my Setup Demonstration YouTube video where I show the tweaks I've done to improve the performance of my phone:

I uninstalled the AdClear app because it just was too recourse demanding and network speed trap. Instead I installed the latest version of AdAway and configured it so ads in all the apps including MX Player successfully and free of VPN and system load. I attached screenshot of the configuration.

Where do you get cm13?

[GUIDE] ROOT - Extreme battery life with 8-10h SOT & Opt for MIUI - Custom ROMs

Hi everyone, this is a guide based on my personal tests, which I have the pleasure to share with the whole community, for experienced users and not. Regardless of whether you prefer to use a MIUI stock or a custom ROMs, these are a series of tricks, Tweaks, passages, let's call them what we want, to get the maximum in terms of battery life, without sacrificing performance. First of all, we talk mainly to have the better experience for MIUI and PRINCIPALLY for ROOTED users, and custom ROMs too. No rooted users cannot expect miracles because there are modifications that mainly affect the entire operating system. I also hoped to find the Holy Grail, but unfortunately it still hasn't happened.
Anyway,: If you want to use a MIUI (preferably GLOBAL, I will explain later why this is the case); the first thing I recommend in addition to a backup (just in case), it's a pretty safe Debloat using the complete Saki tool:
https://saki-eu.github.io/XiaomiADBFastbootTools/
After giving our device a nice cleanup from Bloatware (obviously you choose which ones to remove or not, personally I removed almost all of them leaving only Gallery, Phone and Messages without any problem), the best part comes, and that is to apply all the settings for a better user experience in every aspect. The MIUI is obviously not optimized as a custom ROM, so we should do it ourselves. Personally I am a root user, so first of all I flashed Evira Kernel and Magisk (with which I am wonderfully) and put modules that I personally recommend: LKT (or others similar modules), Syconfig Patcher (they are the ones that interest us), but of course the appearance rooting is optional.
But back to optimization; for each application that we will install, we will have to configure its type of activity in the background based on how much you want the app to act in the background. For example, the "MIUI Calculator" app, which I almost never use, will have set "limit app functions", otherwise applications that we will use more often will suffice "MIUI optimization", such as "Youtube", and what more important, for apps for which notification is essential (such as Whatsapp or Gmail), remove the limitations.
But it's not over. Write in the settings menu "change system settings", then a list will open with all the apps we have installed. Clicking on one of them, a menu will open, where clicking on "battery and performance", we will choose whether to put the limitations in the background or not, same speech as before, limit everything that is not necessary, inverse speech obviously goes for app important to us (gmail whats etc), which we will leave free to act in the background.
Still in the "battery and performance" menu, click on "battery optimization" and optimize everything you can, except as usual, the apps you don't want to be limited as in the previous two steps.
Now we can activate the "Battery saving" mode, which will obviously work on the whole system, except for all the apps that we have NOT optimized before. They will absolutely not be touched. (A nice break of *** optimize the MIUI , Doh!)
Remember that at the beginning of the guide I told you "better to focus on the global rather than the ROM developer?" well, using a third-party tool like Kernel auditor (personally I use EX Kernel Manager with which I am wonderfully), in the dashboard the developer rom had higher CPU peaks than the Global.Il that involved higher consumption. And it is a tool like this "Ex Kernel Manager etc" that we will now configure.
Step 1 Configure the Governor.
The mode and the speed with which the processor passes from the maximum frequency to the minimum one is regulated by the so-called * "Governor"
There are more than 100 different types of Governor for kernel, more or less different; but not all Governors are present in the Kernels. In case you are using Evira Kernel, my advice is to set the CPU to the "Alucardsched" Governor which offers an excellent compromise between performance and battery life.
EDIT: Recently tested zzmove gov with Evira Kernel: little performance is lost compared to alucardsched, but the battery benefits. Personally i have chosen profile 3 (ybatex).
Step 2 I / O scheduler
It is precisely a program in the form of an algorithm which, given a set of requests for access to a resource, establishes a temporal order for the execution of such requests, privileging those that respect certain parameters, so as to optimize the access to this resource and thus allow the completion of the desired service / instruction or process. In this case, I recommend setting it to noop or Zen, for an approach closer to the battery.
In the GPU section, if you don't use particularly heavy games, (personally I play every now and then in clash royale and I don't have any kind of lag at all) you can also set up your own governor here, setting one like Powersave, but in any case this is completely subjective .
Once everything is set up, all that remains is to talk about the last aspect,
the Doze.
Originally introduced with Android Marshmallow, it allows applications and various activities in the background to "sleep" when the device is screen off. Of course over time it has been increasingly perfect, which is why: In a Stock MIUI you can afford to download Naptime, Servicely or Greenify if you want (personally I use Nap & Serv) to enhance Doze or hibernation as in the case of Greenify (excluding as always the apps we want to be in the whitelist).
IMPORTANT: different words must be made for Custom ROMs, which being already optimized, and having a definitely more effective Doze than the basic stock, DO NOT NEED third-party apps like Naptime or Greenify. In this case, even setting everything as the guide, notifications will not arrive when the screen is off, except when you unlock the device.
so as far as custom ROMs are concerned, you just need to limit the apps as in the guide, leave in the background those you don't want to be touched, and always remove the optimization for these "important" apps, I always repeat "whatsapp gmail etc". In this way you will be able to activate energy saving quietly, the apps you prefer will not be touched, and you already have a Doze optimized like the rest of the system. The only thing that applies to Custom ROMs, is always to set the Governors as described above.
That's all at last :fingers-crossed:.
Attached here are my screenshots, with 8 hours of SOT, DIVIDED IN THREE DAYS, so sometimes the phone was idle as during the night or at work. With these configurations, in a single day, or in a day and a half, you will easily arrive even at 10 hours of SOT and maybe even beyond. I hope you fell asleep while reading, but I wanted to make a guide (even if long), to explain to those who may not be very practical, some things that can always be useful. A simple "thanks" is always welcome!
Greetings .:good:

Two more things: for more battery saving, u can disable automatic sync in settings menu (so sync when u want), and probably after some rebooting, it is possible that the governors will reset itself to the default one. So I suggest you check it out.

Really thanks for your concern about battery life stuff, and yup indeed on custom ROMs sometimes we can get up to 10hrs SoT without any mod or even a custom kernel (my experience)!
I'm looking forward to see how long the battery will last when we get Android Q update from MI..

Thank you very much! If I am not mistaken, beyond the various new functions, the "Extreme battery savings" will return. With an adequate optimization, as above (also to be as clear as possible with any type of user), we hope to see many beautiful new performances :fingers-crossed::fingers-crossed:

I hope that MIUI 11 will bring some new battery saving techniques as well!

Thanks for the guide, with it you cleared some doubts that I had, I just have a question, for battery/performace Anxiety can be better than Zen? For what I read the past days is an optimized version of Maple wich gives good balance between battery and performance.

Thanks bro; Zen and Anxiety are so similar as they are also different. Each I/O scheduler we choose can be the most indicated according to what we do with our device. Let me clarify: Anxiety is better in term of battery saving comparing with Maple, "It prioritizes reads over writes but tends to starve writes more".
Zen is based on noop and deadline, very stable and have a great balance, for this reason i choose it. But as mentioned there are no schedulers better than others. But better according to our needs. My advice is to try them both, and see how you are in your daily use of the device :fingers-crossed::fingers-crossed:

Battery life is not the only thing I look for. Stock rom batter life is good enough after debloat in many crapps using saki. Stability, functionalities, security.. overall stock rom is the way to go for me at the moment. Did you mention restricting permission on apps?

Welp, after playing Free Fire for 1:20:00 and PUBG for 4:00:00, a little Browsing, my battery usage was of 76%, I don't use LKT because last time I try it my wifi started working weird, only use Snaptime. Evira 2.2.
:good:
I would like to know what do you think about zzmove governor that was added in Evira 2.3. Thanks.

I tried to use your settings but at reboot all configuration change to interactive or schedutil for CPU, msm-adreno-tz for GPU e anxiety for Scheduler I/O. I guess there are some conflicts with LTK.... I don't kwow how you have 8 hours of screen on your device...

Mate, if u read with more attention, i wrote about it in my second post..
Just reconfig Governor already. It could be happen, is normal

Im going to test darknesssched with zen without sysconfig patcher (Had mobile data connection issues), alucardsched give me a little lag in PUBG, when I use darknesssched that dont happen, zzmoove dont convince me, it is based in conservative and hasnt been updated since 2015, for what I know cpu governors schedutil based are more "smart".

Yep

Hm, i am locked...and have no kernels installed. And I'm not planing to do it.
Did restrictions and debloat and this is what I get.
Since I am on 10.3.5. my battery is weaker..
On 10.2.7 I had 2 sims with lousy signal, and I was having about 7,8 h of sot and same use.
Now before this tweaks I was hardly getting 5h in 24h
Yesterday I had weaker use then ussual but still, this isn't very good..but I think it is better.
I dont like this 10.3.5.

[KERNEL][FORK]Radioactive Kernel V2.2.5 [2021.07.28][OOS/CUSTOM ROMS][UNIFIED OP8/OP8Pro/OP8T] 295-920Mhz GPU + WL Blocked + Adreno Boost

Updated 7/31/2021 rebased on Acuicultor's v2.2.5 rebase (OOS) and rebase_custom (custom ROMs).
[NOTE: Bug reported - with a Magisk Module I created to fix it. For some strange reason (code looks fine), some systems are setting the default GPU frequency to 920mhz and default power level to 0 (max). I have posted a small Magisk Module that waits 5 seconds then corrects these values (295mhz default and power level 8). It's on the GitHub release page - MOD-GPU-Set-Min-Freq.zip. Just install with Magisk Manager as a module / install from storage after downloading.]
This is a tweaked version of RadioActive kernel by acuicultor modded for higher performance and lower idle drain. All source commits and releases are on my GitHub fork:
https://github.com/mrslezak/Radioactive_kernel_oneplus8/releases/tag/v2.2.5-MOD
PLEASE read the Readme as well as the disclaimer. Whenever you flash a custom kernel, you do so at your own risk. I recently rebased on the dev's work (GPU_OC OOS branch, never released) and set the wakelock blocks up myself (lower idle drain, tested over a week with no loss in functionality), dropped the base GPU frequency to 295mhz and raised the top ones (800/920mhz) acuicultor you're an awesome dev, great to have you around! All credits should go to him other than my tweaks.
I also merged all the same changes into the Custom ROM branch which didn't have GPUOC or AdrenoBoost - several people are using it now but it's marked as a BETA since I am on OOS (latest Global) and can't test it myself. NOTE: many people on the TG channel I posted to have tried it and have had no issues on Op8, Op8 Pro, and Op8T.
Note if you are one of the rare people who see artifacts in games or benches, the easiest fix is to go into your kernel manager and set the max GPU frequency to 800mhz and apply on boot. Not all 865 Adreno GPUs are created equal. I haven't seen one that couldn't handle 900mhz to date, but enough people have had no issues at 920mhz so that's where I put it.
Be sure to flash Magisk before installing, then use EX Kernel Manager or FK Kernel Manager to Flash the kernel zip. It has all the same optimizations of RadioActive kernel, just modded for really nice performance and low battery drain. Adreno Boost is set to low on default which makes it react faster as the GPU scales. If you already have Magisk installed, there is no reason to reinstall it - the AnyKernel 3 zip installer will use what's installed already.
I put one out there you can just flash from: fastboot flash boot 4.19.110.RadioActive-WL-295_UC-920-GPU-2.2.5.img (OOS only) as it saved my a$$ a couple times when flashing or trying to apply an incremental update when rooted (no success, although I posted the incremental update on TG, the payload just won't extract properly to update using fastbootd scripts)... Maybe I'll post it here on XDA and see if anyone can extract the latest Op8T update.
Also someone sent me a PM about using KonaBess app to change frequencies even more, or change regulators, or change the DDR clock speeds. Yes, it works. Note you probably should only play with that if you have a fastboot image available in case it doesn't boot! I did just upload one for OOS to the repo as I mentioned above. Be warned, you're on your own there.
Hope you all enjoy!

I built both just moved some commits over from the GPU_OC branch and added my own to custom. I have no way to test it but several others did already. All I've heard is great feedback and running faster than OOS. Of course it depends on the ROM.

mslezak said:
I just built the OOS one... custom I don't think there's a GPU_OC branch to rebase on. I deleted my other repo with changes and just switched to the dev's work since it was nicely done. I'm always running OOS I don't really care to run a custom ROM. Although I imagine it would be pretty easy to add his commits from the OC branch to the custom one, you never know what issues you'll encounter when doing so... And I don't really feel like building a kernel I won't use. I already converted it over from a carrier locked phone. Happy enough it runs on Global OOS ROM. I've run a few custom ROMs before like Lineage, Evolution-X, I always end up back on OOS. Just like having a fast phone with no lag where I can open any number of apps and get work done quickly without waiting for anything to load.

RadioActive-WL-295-920GPU-custom-2.1.4-BETA.zip is the file for custom ROMs BTW if you don't read the notes (which you should). As I mentioned to the unhappy user you can always drop the max GPU in any kernel manager to 800mhz and set on boot if you got an inferior 865 although artifacts have only been reported by 1 person period. A more productive approach rather than bad mouthing someone trying to provide a free service is "can you build a version that maxes out at 900mhz?"... Respect please in the forums.

Well I put up custom and OOS just use a kernel manager to set the high frequency you want it to stop at on boot. But before you do, here's a day of basically using the phone a lot at 120hz with many apps open. Note someone here didn't look at the SOT DRAIN which is 100/8.27 = 12hrs SOT. I didn't start it with a full battery. I do that on purpose start at 60% or so to see how it drains in the middle of the discharge. So I'd advise those that are quick to criticize, make sure you actually calculate something before saying it's "horrible" when it's as good as stock.

You do realize that this is 12 SOT if you never let it sleep and use it all the time, look at the stats and do some math. 100%/8.27% = 12hrs SOT. Idle went up because I was on phone calls for an hour, and the screen turns off. It's usually 0.6%/hr if you're using it (on WiFi), 1%/hr on cell, turning it on and off every few minutes will cause more drain. I was using my phone a lot today that way. I would say that's amazing to get the same SOT on a modded kernel. I haven't optimized a thing in the ROM or notifications, just used the kernel. I don't care if you use it, do as you wish.

The best way to get help, or to find me is on the TG group. There are people there that can help you out if need be.

Ignore the haters and complainers...
I just flashed (RadioActive-WL-295-920GPU-custom-2.1.4-BETA.zip) over CR_Droid (CR 03/08 and 03/26 builds 8Pro) and it made a HUGE difference in smoothness, snappiness and performance. I don't worry too much about battery drain as we can top off our phones in less than 20 minutes a day. The under-clocking is also wonderful. I remember back in the G2 days we not only underclock, but would under-volt ALL the frequencies just a few ticks away from unstable for more battery life (dependent on the cpu bin ver), but not really that necessary anymore with larger batteries and super quick charges.
Much respect and appreciation and hope to see more tweaks and builds in the future

Thanks bud, glad to hear good results with the kernel. On TG everyone has been full of compliments. Let's hope it stays that way here as well. We can conduct everything in a respectable manner.

Now if you REALLY want to save battery and your cell provider supports Voice over WiFi, Google Messages enable enhanced chat features and keep it on WiFi only (i.e. Bluetooth only on while you're using it, Location off unless you're navigating somewhere, NFC off unless you're using GPay, mobile data off), here's what I get being on my phone all day today (started under 60% battery) at 120hz: 7% active drain, 0.84% inactive. If you're asleep it's more like 0.4%. You won't miss any calls or texts either.

great, zero! drain during the bedtime that's awsome! thanks for the kernel upgrade
