INFO
-Kernel with some CPU governors alongside ThunderPlug Hotplug adapted from XePeleato's ESAL kernel, NOTHING MORE.
-This kernel for Nougat ROMs.
-Based on OpenKirin's kernel https://github.com/OpenKirin/android_kernel_huawei_hi6210sft/tree/7.x
-tested on RR ROM.

from ESAL kernel thread
Guide
I am going to try to help you to decide what settings you should apply
First of all, I recommend to install Kernel Adiutor.
If you prefer battery life:
Start Kernel Adiutor:
Go to CPU in the drop-down menu and set as governors PMC or Smartmax
Then go to CPU hotplug and don't enable many cores, since more online cores means more power used. You can also set the Endurance level to Quad-core
If you prefer performance:
Start Kernel Adiutor:
Go to CPU in the drop-down menu and set as governors performance (will set the CPUs to their max frequency)/ondemand/interactive
Then go to CPU hotplug and make sure to lower the load threshold, having a low load threshold will make your phone use more cores (if you experience lag while playing, maybe it's set too low, so use a wise value, do your testing.)
To conclude, I just mentioned where the settings are and some example values, if you love to play games you won't use the same settings as someone that just likes to read emails and use Google Chrome, find the settings you are comfortable with, and don't forget to set Apply on boot!

What recovery and OEM images! , it's just the boot image .
Anyway if you still didn't fix it ,try this .
Reboot to bootloader "keep pressing lower button with power button"
Then flash the TWRP recovery "fastboot flash recovery twrp3.x.x.img"
Now reboot to TWRP recovery and restore your backup if you have one, or install a full ROM
I had tested this kernel and is amazing how much it improve the battery between 14 and 18 hours but I'm getting some lag with PMC and smartmax governor. I'm trying interactive governor and it has less lag but still there is a bit. Is there any option to get a balanced performance without lag?

Try one of these and test.
1. Enable touch boost and lowering load threshold to maybe 50℅ , in CPU hotplug settings.
2. If you want, you may disable the hotplug and be satisfied with the PMC governor.
Thanks a lot, this kirin 620 is so freaking boring and lacks a lot of control maybe finally with that kernel i can be happy again. I'll test it on my Y6ii running RR 5.8.5, just one question tho; does this kernel since it has lots of other governors allows me to fully control the 8 cores ? (I'll test it and post here but thought maybe somebody already have the answer)

I am pretty sure only 4 cores work, yes there is actually 8 cores but under all conditions and using all possible governors from all available kernels there is always only 4 cores working! I am sure that the other 4 cores are disabled completely on the chip so no software modification can make them work! ( kinda the same situation on desktop CPU where its called a dummy die, basically its present there and electrically connected but servers no purpose but being there ).
Why i am pretty sure! is because i've done tons of testing using lots of benchmark apps; by using the single core and multi threaded score, you can notice that the score multiplier always end up round 4, i even checked older gen CPUs benchmark and they're doing much better scoring in 99% of the apps i tested. And besides, lets talk real word tasks! Does that P8Lite/Y6II feel like a powerbuffed 8 core threaded phone? My old S5 with the quad core Snapdragon 805 Soc does a better job in most cases if not all!
I think Huawei just used an Soc with dummy dies just for marketing purposes, as most users would never try to investigate the real performance of the chip and just use the phone for daily stuff so hearing the word 8 cores CPU with "XX" price really pushes you into buying it! I will test more but i am pretty sure i'll find that same result!

Nope, all cores are working, we have 2x4 cores. You can find it in dts!
Second cluster is working but apps can't get info about second cluster usage because there's no cpufreq folder inside cpu4/cpu5/cpu6/cpu7 folders which you can find here: /sys/devices/system/cpu.
Another proof? Here you are.
Go to /sys/devices/system/cpu/cpu7 (this is "directory" of our not working 8 CPU), then open file called 'online'.
Hint:
1 means it is on
2 means it is off

Some apps can detect the real cores, like system2 and lspeed, there you can see that is has real 8 cores in 2 clusters I guess, this is why the second 4 cores are almost "invisible" and it's usable under high loads, like games and apps.

I think, 4 cores for Foreground and 4 cores for background processes, for stable switching from app to app! Maybe I am wrong, correct me if I am!
I was doing more tests to this kernel and found out this page to improve interactive governor
https://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557
I installed ex kernel manager app and load a profile (thanks to Dazeone), battery was improved notoriously and performance is very good. I share the link and the profile file (copy to internal storage/ElementalX/gov_profiles) just in case someone wants to try.

No, sorry.
If you want a certain feature I may try to do it, but after 2 weeks.
Also you may want to try build it by your self, there are plenty tutorial in XDA-forums, I did that without any knowledge of anything ,lol .

I don't have enough knowledge about kernels or such to argue i am more of a computer guy, so i did put it in a very simple way, besides apps detecting or not detecting those extra 4 cores, through benchmarks the multiplier you get from dividing the multi threaded performance number by the single core performance number is always around 4 and i've seen this same result in like 5 benchmark apps.
Another theory (if you wanna call it that), this Kirin 8 core cpu even though it newer can't match the performance of some old quad core snapdragons CPUs, as i said my old S5 (With 805 not 801) is doing significantly better in all tasks! without forgetting the ability to shoot video in 4K and its way older as well!
Maybe its really 8 cores but i only see the performance of a quad core chip (even slower imo), tried to compare it to a friend's S4 with an exynos quad core and they did match up a bit.
And i'd be really thankful if you can correct me and throw some knowledge at me!
The performance of CPU is controlled by many factors,
Cores, frequency, ALU structure, OS, application's threading, and more.. so u can't compare 2 SoCs by number of cores.
Moreover, the people in this forum mis-understand something, that the 8 core CPU is built to reduce energy consumption, NOT to improve performance.
To make long story short, 8 core performance =\= 8 * single core performance.

What this app is gonna do?
This will give you some boost that is really required to play games that are demanding on GPU front.
What this app require?
You need to be ROOTed and for that there is a really great app with one touch facility available! The link is http://forum.xda-developers.com/showthread.php?t=2387507
After you get ROOTed just install the Tegra Overclock OUYA EDITION app from attachment and click on OK for one click optimization.
You can also change the actual resolution to somewhat lower to again get a massive boost in GPU intensive games or shall I say those games that scale with GPU clocks very well. (I can confirm nearly 2X boost in RipTideGP2 with all settings maxed out when comparing with 1080p to 720p option provided in the app :laugh
Any kind of hazardous warning before use?
If anything goes wrong then you know where the power switch is! Close the console and cut the power and start again. We have not implemented the on Boot settings for safety reasons...
What about future updates?
I just wish that 4.2.2 gets for the OUYA and that will be a game changer for the console as that support full screen scaling on resolution changing vs screen compensation provided by current android 4.1 version....
NOTE: The app is fully free to use one click solution for OUYA owners and don't require you to get involve in any of cracking stuff Still the app does costs us in development and support front so any kind of donation will be greatly appreciated. If you are planning to buy any Tegra device in future then you can support us by purchasing the original Tegra Overclock app from the market that will in turn benefit you as well..
BTW don't forget to hit the thanks button
EDIT: Version 1.1 Change log
*Nothing new just made the interactive governor as a default rather than performance governor due to heating concern.
*Checked the code so that 2D GPU is set to 520 MHz too, in case it still reports half let me know..
EDIT: Version 1.2 Change Log
***Added requested LBCMT (LastBootCpuMaximumTemperature!) This shows the maximum temperature your device went during last boot.
***Added apply on boot (Works only when the USB device with at least a single file is detected to ensure you don't intentionally mess up anywhere )
The LBCMT will works as soon as you boot once after you open the app for the first time. Also note that YOU SHOULD NOT KILL THE APP manually by task killers or the reporting will be fake. BEWARE....
EDIT: Version 1.3 Change LOG
***Full screen stretched resolution support for CM11 Rom users. Use the special newly added resolution (will only work for CM users currently as no other 4.3 or 4.4 Roms available)
Fixes for temp not showing on custom kernel like EPRJ Kernel.
Thank you for being patient.

This app has a one click solution (found in the op). All you need to do is click the button and your ouya is optimized. The op already has this information.
On another note, this app rocks. Thank you.
Awesome, finally the OUYA version, im about to jump on this right now and give it a spin!!!:good:

Just Press the OK button and wait a few seconds as the settings getting applied. After that Run your Emulator Games and you should notice a difference . Note that Resolution options also cuts the screen area so use them only if a game is unplayable!
is there no way to allow users to set advanced profiles so that they can configure a medium and max overclock setting?
i saw the temps on my core rise up pretty quickly just from fiddling with the UI, not sure if I want to subject this little guy to that much abuse with no really efficient cooling solution under the hood.

it's understandable for the lil guy to get hot quickly when you are overclocking the GPU+CPU, can't expected to run cool unless you put a better cooling fan into you console, i don't mid my ouya running a lil hot, well mines don't get hot enough cause my ouya got a acrylic custom shell with enough vents and airflow that keeps my console way cooler then the ouya stock/factory shell...
its obvious that it would run hotter if the clock speed is higher. no one is disputing that. i just don't see how not allowing the user to specify speed as much of the other CPU overclocking programs like SetCPU allow the user to do.
It's a needed feature IF it can be supported and implemented.
Excellent!
I'll give this a bash tonight and see what improvements there are!

Actually Temperatures are no problem for this chip as it can bear temperatures of 70 C with great ease as the manufacturer mentioned. Don't worry about that also let me know if they are above this temperature so that we can do something about that. If you ask me I am comfortable with 85C as that is what the throttle temperatures (Default mind you!). Just Relax and crush the games already

The custom CPU clock feature conflict the one click feature and not to mention lower clocks are not required as there is no trouble with the highest speed since the cooling is active and with sink. Just don't worry about the temps too much as everything is normal here and the purpose of console is to bear high temperatures with high load even with little heat management..
I have both the old app and the Ouya specific one and it looks to me that 2D GPU clock is set to 260MHz (1/2 of 3D clock). @Kingshoo, can you tell us what the "one click" settings are (governor, CPU clock, GPU, etc).
Much appreciate the work you've done.

Oh really If its working on Half then I will bump that to full to in next iteration
Settings are nothing but final settings in one click. Meaning Performance governor (Because this one has no polling overhead as opposed to interactive). GPU to 520Mhz, CPU clock to 1.7Ghz (1.6 on all 4 cores as set by OUYA). Ram at 800Mhz and also no throttling on Ram and GPU so that performance is reduced only due to H/W limitation or by bad coding practices and not due to some power saving logics

Cool...thanks! Looking forward to v2
BTW...for reference, I had my governor set to performance for a while and it drove the fan to run almost at all times. To the point I ended up shelling 20 bux to buy the Noctua quiet fan. Maybe others have better luck with the stock fan - but if noise is a concern, I found that the "Interactive" governor scales pretty fast with no visible impact on performance vs "Performance".
My 2 cents.
After reading several reviews about Noctua 40x10mm A-Series Blades with AAO Frame, SSO2 Bearing Premium Retail Cooling Fan NF-A4x10, I decided to buy it. I replaced the noisy fan of my OUYA, and the difference in sound is amazing. I had to check if the fan was actually running because barely hear it. Also, the temperature of my equipment dropped ~ 10°C, so overheating issues could be easily fixed, if you decided to overclock. I recommend this product without a doubt. Check on eBay or Amazon.
If you want to replace the fan, here's a guide how to do it. youtube . com /watch?v=rra0FwlHvBA
Well honestly I wasn't able to play games on OUYA but since you people are playing games what the temps of CPU are anyways after say an hour? I am asking this because I don't see a need for custom coolers as 50C or 70C it really don't make any difference to your hardware. Yes the fan noise may be concerning to many but I have cotton plugs in my ears to keep it silent (these really costs cents and not $$!). OK so newer version will have interactive on one click..
My stock fan is totally silent anyway

Greetings,
This driver is obtained from Qualcomm's 07 Aug 14 drivers for "Qualcomm Adreno 3xx GPU on Nexus 4, 5 & 7 devices running Google Android 4.4.4 KitKat".
All credits go to the folks at Qualcomm for making the developer version of these lib files available for us to play with.
This is for testing purposes only. Please don't flash without backing up first and then start screaming if something happens to your phone!
The package only contains files for Adreno 300 and 330. I cooked the packaged to be flashable on our SM-G900T or any SM-G900 with the Adreno 330 chipset.
I'm on a "XtreStoLite_G900T_ROM_v1.3_UVU1BNG3" ROM, which is a super clean/slim version of the stock rom. This is also Android 4.4.2, my AnTuTu benchmark results dropped from 37400 to 35800 after flashing this package.
I'm requesting someone with a KitKat 4.4.4 ROM to test this and report back their before and after benchmarks.
I appreciate your feedback,
Hmm, interesting.. I'm only on 4.4.2 or I would help out..
Turned out the 3D performance on antutu version 5 with this driver puts our phone one head and shoulder above everyone else!

And this means....... I'm sorry but I don't understand the purpose... Is this supposed to make Tw snappier?
Thanks in advance!
It is updating the video (graphics) drivers. It probably improves the touchWiz performance as well (don't have evidence to support this), but what i noticed was a huge performace increase in the 3D graphics score. This will make games run alot smooter and more efficiently.
To clarify, this file resembles how your Mac/PC has a video card with say NViDIA or ATi video cards and they have their own driver releases. Our phones graphic chipset is designed by Qualcomm and it gets its own drivers as well. Hope I answered your question, and didn't make it worse!

In order to get any real "TouchWiz/Nova/Apex/etc" performance increase from it you'd have to flash this, then venture into Developer's Options and enable Force GPU rendering and Disable Hardware Overlays. And even then our device is so performance driven that you likely would likely not even realize the difference other than giving the CPU a break for a few cycles and possibly seeing a battery life increase depending on whether the CPU or GPU pulls more juice. These drivers are largely made to increase the 3D performance of your device when gaming and while it wasn't meant for us I'm glad to see someone took the time to let us benefit from it.
I'm going to flash it on an NG4 (4.4.2) release and see how it holds up to GPU rendering no hardware overlays. I don't game so if you want an objective test on that someone will have to pick up my slack. I'll report back when I know if it truly impacts it.
Tried flashing the update and ran into a couple random fcs for a few apps. Nothing device-breaking or anything, but I also didn't notice any real difference in performance or framerate in games. But I do appreciate you posting this, I'm always up for trying a little experimentation on my device to find something new. Thanks man.

Don't worry, I didn't forget about you. It takes a few days to really put it through its paces. But here is what you want to know: It works in 4.4.2 Touchwiz (Alliance Rom B4 for me)
Performance Increase in ROM function and control with "Turn Off Hardware Overlays" and Force GPU Rendering: Check
So I tested this by underclocking my CPU to the point where lag was perceivable in things likes app launching, keyboard typing, app draw opening, etc. I dropped it down to about 1200Mhz on all cores and then disabled HW Overlays. It was night and day. After the GPU took over rendering my CPU clock speed hardly moved all of the items previously lagging went right back to being fluid.
So does it help with Rendering in the ROMs? Yes, it definitely can.
The other concern people have is with battery life that goes with GPU rendering and the claims are that the GPU uses more power than the GPU. In my preliminary testing, what I noticed was lower overall CPU temps while Hardware Overlays was off, lower CPU clock speeds since it didn't need to render apps, and a small decrease in battery life.
In the power draw category I need more time with BetterBatteryStats and I need to adjust some variables. I want to underclock the GPU to the point of perceivable lag (if that is possible) and then I want to adjust the governor with KTweaker and see if I can't get better battery life. I will simultaneously lower CPU speeds to keep my core temperatures down and keep the battery cool. If these things are successful and battery life is interchangeable between the two, I may run the GPU full time for rendering the ROM. Keep in mind though, only custom kernels allow this kind of tweaking. If you use a stock ROM you are stuck with CPU and GPU clock speeds where they are so battery will drain faster.
Give me about a week to test my theory on this and see if I can find an equilibrium for CPU and GPU temperature and speed. I'll post the profile I used with KTweaker when I have my results. Until then, if you want to help and find your own settings and post them here along with battery life that would be awesome.
Edit: For what it is worth, to test application launch speeds and UI fluidity with the GPU I completely turned off system animations, I set Nova Launcher Animations Speed to Faster than light and scroll speed to "Fast" (personal preference). I got the same, or better response time using the GPU to render the UI.

Don't worry, I didn't forget about you. It takes a few days to really put it through its paces. But here is what you want to know: It works in 4.4.2 Touchwiz (Alliance Rom B4 for me)
Performance Increase in ROM function and control with "Turn Off Hardware Overlays" and Force GPU Rendering: Check
So I tested this by underclocking my CPU to the point where lag was perceivable in things likes app launching, keyboard typing, app draw opening, etc. I dropped it down to about 1200Mhz on all cores and then disabled HW Overlays. It was night and day. After the GPU took over rendering my CPU clock speed hardly moved all of the items previously lagging went right back to being fluid.
So does it help with Rendering in the ROMs? Yes, it definitely can.
The other concern people have is with battery life that goes with GPU rendering and the claims are that the GPU uses more power than the GPU. In my preliminary testing, what I noticed was lower overall CPU temps while Hardware Overlays was off, lower CPU clock speeds since it didn't need to render apps, and a small decrease in battery life.

I haven't tried it on CM yet, I'm about to flash the 09/04 build of CM11 by Albinoman with KT's kernel. But I won't flash these drivers prior to running the build 24 hours or so to make sure there aren't bugs that existed before flashing the files. So, if you've been running CM for awhile and want to test this build just nandroid, flash, and report any issues.

You guys make me sad. Benchmarks are not now, nor will they ever be, an acceptable means for telling you how capable your device is. Your scores in AnTuTu are about as capable of telling you your phone's speed as your ESN is at telling people who your phone belongs to. It is just arbitrary numbers that will fluctuate up and down based on the slightest inconsistencies.
Drivers, just like in Windows/Linux/Mac, are meant to optimize the performance of your hardware. That's it. This driver likely optimizes the GPU cycles to make it more efficient and lower heat output while performing better in games. You know why hardware review sites start out with benchmarks saying what it can do in a perfect world but still ends the review by telling you it gets 75 FPS in Borderlands 2? They do that because while synthetic tests are nice, what would be the point if our games don't play better? It is the same concept here.
I'm begging you, uninstall AnTuTu, re-install your favorite mobile game and just base performance off of whether it plays better or not.
Side Note: Drivers didn't appear to do anything in AOSP CM11 when I gave it a try. Sorry I am so late on reporting in, college takes up a lot of my time. Also, using the GPU to draw your applications does eat more battery whether you use these drivers or not. So there is no marked improvement from lowering CPU speed and using GPU only to render.

I figured since the OP stated he got less points in Antutu, I would go ahead and use the same app and test to compare...
F*ck me right?
Regardless, I don't notice anything different either, my stats are in the sig.
Can anyone explain to me what is better?
I know that underclocking reduces cpu frequency, which means lower temperatures and also better battery, but performance is worse, so it takes longer to complete tasks...but if it takes longer to complete tasks, it means it will also have screen on for a longer time right?so it saves power from the cpu, but keeping the screen on for that extra time also means it will consume extra power right?
About undervolting, is it better to undervolt or to underclock when it comes to battery life?i know that with undervolting there is less heat produced because of the reduced voltages. From what i have read (i dont know if it is correct) the power consumption is given by this equation: P = f*c*(V^2) where f is frequency, c is capacitance and v is voltage. It makes sense that reducing voltage means less heat, but if i reduce CPU frequency it also produces less heat because it reduces power. Most of the time i read that underclock is better for battery because it uses less power, but like i said earlier, it takes longer to complete tasks and in result i have to keep the screen on for a longer time.
About hotplugging, i have seen some users with good battery life screenshots, and mentioning that they disabled hotplugging, because they said that turning cores on and off also wastes energy. So is it better to hotplug or not?
would really like to get some answers because i know nothing about this..I also know that i could test each setting and and see which is better, but i dont use my phone the same way everyday so its kind of hard to determine...
Short version and after extending testing (2 cores max, -175Uv, underclocking at 1000 or 1300mHz) with different kernels and always on stock Rom,
the result was that there was no noticeable difference at the battery life with a normal setup of using of 4 cores at normal max freq of 1512mhz.
A custom kernel in comparison to the stock kernel makes more sense cause of the optimization they offer for performance and battery life.

There are different hotplugging methods.
The stock one as a boost feature, as soon as u touch the screen ur decvice goes to dual core 1026mhz for a couple seconds even if the load is super low.
Custom kernels have many variants on the hotplugging "style". Most of them dont have the touch boost included to save battery (but u can have the same kind of touch boost enabled by the governor, ex: franco kernel). Others simply advise u to turn off hotplugging == less calculation of the load to decide if the device needs to plug it or not + no waiting time to get the performance boost of many cores online (since all 4 are already online) + somewhat more heat since all cores are allways draining battery.
Im no expert and i hope all i said is right, at leats its what i know.
What i personally look for is:
Min core 1
Max cores 4
No touch boost (no heat while u are simply texting via sms on 2G with data and wifi OFF)

actually touch boost and hotplugging are different things...touch boost is a feature where as soon as you touch the screen, the cpu ramps up the frequency to the specified touch boost frequency. Hotplugging is a different thing, where cores of the cpu are turned on and off when the phone does not need them to be on all at the same time. I know that touch boost drains more battery, but i dont know about hotplugging...would like to see some tests/benchmarks, but i dont think there are any...

Different things but on stock kernel touch boost is implemented on the hotplug and not the governor.
Any difference btw 4 cores online or hotplugging must minor, and have draw backs on heat wich affects the battery capacity.
Eventhough u can say that hotplugging may drain an amount of battery to plug and unplug cores, i would say its minor.
Talk to @simms22 , he is the "trinity kernel guy", four cores online is a must for him

From my experience, under clocking as well as running a 2 core setup doesn't change anything for the better. Most times for the worst due to a worse user experience.
Undervolting is something that, solely from the physical side, cannot make things worse (unless you under clock too much). Undervolting will make your CPU cores use less current. Less current running through an electric circuit always means less heat, too.
To put it simple:
If my regular voltage at 384mhz is 950mv and I lower the voltage to 800mv and after testing it proves to run stable my device now uses 150mv less on that frequency.

no matter what you do , its still going to be a mediocre battery life , best leave it as it is because the way nexus 4 is designed its still going to be getting annoyingly warm on games
Well, from my own experience undervolting definetly reduced heat and made the battery last longer. Don't expect 2 hours more sot, though. Its most notably while the device is idle.

Without a custom Kernel, nothing much can be tuned in Kernel Adiutor to achieve higher performance in games. OC-ing the GPU and CPU would be probably the only solution to gain more FPS. All this ROMs are gonna perform similar with the same kernel.

optimization for games in kernel adiutor is actually pretty straight forward. just choose performance governor for both cpu and gpu and lock both to the highest possible clocks (cpu minimum and maximum 2016 mhz, gpu min and max 650 mhz). that way they wont be downclocking to save power and ull have max performance always
furthermore, u could change IO scheduler to deadline for faster loading times and disable core control (as well as temperature and vdd control, depending on whether theyre active by default) in thermal tab. just keep an eye on device temperatures, cuz ull be basically removing throttling measures for hardware safety. although i doubt this should be a problem with an soc like SD625 in such a large device, but still...better be safe than sorry

ok i just checked on my phone with LOS 14.1 installed. when u set min and max gpu frequency to 650 mhz and set perfomance profile the gpu will only downclock to 320 mhz if there is no load put onto it. if there is ANY load whatsoever (in my case a simple continuous finger swipe over the display) the gpu clock sticks to 650 mhz and stays there.
so no worries, uve unlocked ur SoC performance completely and ull get the most out of it during gaming
edit: btw, dont let the poll results fool you. most people just go with LOS because thats what they are accustomed to the most and because its been out the longest for mi max 2 as far as custom roms are concerned. so more people voting there doesnt mean its actually faster than other roms (likely that most people havent tried ALL roms, especially for gaming-specific purposes )

Sorry I won't be much help on this as I haven't needed to change frequencies in a while. Afaik you just need to change the CPU and GPU governors to power save and set it to apply on reboot, small cores like to jump up a lot more max freq than the big cores so maybe around 1500mhz for small, keep large cores from going into 2000mhz and prime core too, GPU from what I remember really struggles if limited to lowest frequency, 300ish is a good starting point.
Depends on what rom you are running too, miui you don't really have a choice but to use stock kernel. On custom rom you have a lot more choices of kernel like immensity, f1xy, kraven and notkernel.
