Hello guys,
I`ve been trying to find a way to have all 4 cpu cores online all the time to see if it helps playing games (lag) as I tested, for me every game lags when there is only 1 core running, than when the phone needs more power it turns on other cores and it lags, on that exact moment!
Trying Glowball, Tegra 3 game doesn`t lag because every core is on 100% of the time! And I`ve seen users saying that they don`t have lag on their phones because every core is active during gaming sessions, which is not my case.
I tried to use System Tuner Pro > Boot Settings > Force all CPUs online with no success and didn`t try CPU Editor as I don`t know how to install it.:silly:
If you have lags on gaming this might be a solution!
Does anyone know how to keep`em online all the time? 10H here.
Thanks for your help. :fingers-crossed:

Well Glowball doesnt lag because they optimized it for a tegra3 devices. so the problem is the game developer, not the phone as far as i know.
i dont know if what you want can be done.

Well, Shadowgun THD is in theory optimized and lags anyway. It`s just frustrating to have a quad-core high end phone that lags on so many games.
But thank you!

I am playing Shadowgun THD without lag I dont know why, But yes u are right about this problem.
I have tried playing most wanted It iagged but I noticed that the procesor speed are 520 mhz or such, and it makes problems,
So I put maximum 1500 MHz as minimum speed clock, but after playing more then 5 minutes processor speed was not more than 1000 MHz (even with root setup).
It turns that the problem is in the kernel, it is some sort of OVERHEATING protection.
But I am pretty sure that all 4 cores were active even the speeds didn't go more than 1000 MHz.

its not a overheating problem. i play MW and theres is alwasy only 1 core at 1500MHZ at 95%. If the game could use the other cores, it wouldnt.
remember htc has exactly the same problem... its the developer fault coz there is apps and game optimized t use all cores when needed
This sucks right? If this could be done I`m quite sure that the lag problem would be solved or minimized greatly!
If anyone knows something about it please let us know!
Much appreciated.
First if you forced all the cores online ,, then you can use your phone for about 2 hours with overheat . So you will lose your battery .
and about the games it is a problem with our ''kernel'' ,, the kernel is controlling the cpu and the hardware . LG optimized the kernel for long battery use and if you noticed the cpu takes a long time to change the frequency . LG made the phone for daily use .
To test CPU use benchmark ,, not games , games are very complex application and maybe isn't compatible with tegra 3 .
Our phones have nearly the same Galaxy S3 benchmark scores .
And if you noticed our CPU is excellent with miltitasking
you can say our CPU has a hidden power .
Any custom kernel can solve this problems but we have a locked bootloader . So we should wait until JB which has unlocked bootloaders (as LG said)
Trust me, making an app that can even run on more than one thread is hard; very hard

i have that exact same problem and it IS caused by overheating..when temperature goes over 36c the max speed automatically resets to 1000mhz if the min speed was above..but when temperature is below most games work flawlessly

When playing dead trigger, mone will usually run 4cores 100% at 1500 until it reaches 42°
But I know that if, you play music it will keep at 1000 no matter what the temp is

I only faced game lag issue when my device is over heated or when playing multiplayer games (like SG DeadZone) with bad internet connection..never faced such issue due to CPU?
To overcome heat issue I have underclock max speed to 1.2ghz with CPU Tweak app..and it has helped a lot with over heating as well as battery life, and never faced any issue with lag even with 1.2ghz speed..
I have read in many place that even HTC One X behave similarly until JB updates arrived so you dont worry much even if some configuration or app in your device is creating game lags, it will be much better with new JB updates :fingers-crossed:
Quick note:
The Tegra 3 can run only in Single Core mode on 1.5GHz, in other words when your CPU reads 1.5GHz, only one CPU core is being utilised. If you actually want to use all 4 cores, you should set the max frequency to 1.4GHz to avoid the CPU clocking up to 1.5GHz. Lag is caused by switching between all 4 cores on 1.4GHz and single core on 1.5GHz.
I cannot set the max cpu speed. Tried different apps, iam on stock rom v10h, with root, new on p880

actually hardware wise tegra 3 is capable of running all 4 cores at 1.5ghz however almost all of current android app are not optimised for multicore cpu..however i have noticed when monitered using apps that it somerimes uses all 4 cores at 1.5ghz.
However its better this way if its not running all 4cores at full speed...infact i have underclocked mine to 1.2ghz this helps alot to over come heating issue as well as battery life and no issues with HD games :thumbup:

I'm referring to the Tegra 3 T30 present in our devices. The T33 in the HOX+ can run at 1.6GHz in quad core and 1.7GHz in single core. However, the T30 can only run at 1.5GHz single core and 1.4GHz quad core.
To cite Wikipedia,
Tegra 3 T30: 1.4 GHz Quad-core ARM Cortex-A9 (up to 1.5 GHz in single-core mode)
IIRC over at the HOX forums there was a thread on CPU management to prevent lag spikes in games when Tegra 3 switches from quad core 1.4GHz to 1.5GHz single core or something along the lines of that.

This app is getting famous now, but in case you didn`t see, it`s called tegra overclock (not tegrak!) and it manages to force every core online pretty well. It has some good other features too.
It`s paid but it`s worth it.
not to mention it DOES improve your gaming experience.

Hi guys!! I was thinking about opening a thread where everyone can specify what's the better kernel setup, according to her/his own necessities, and share that configuration with all p880 community. Also, it can be submitted the relationship between the kernel and the ROM an user is running on the device, to compare performances and make each other more conscious about kernel tweaking. I think it's better to open it in general section, so everyone can write, without being scared by submitting something not related to developing.
This thread won't to be in any way a substitute of the "Battery life!" thread, so if anyone wants to post specifical results or screenshots about battery duration, please post them here:
http://forum.xda-developers.com/showthread.php?t=2478514
Said that, the idea is to post a message like this:
KERNEL: name of the kernel you are using
ROM: the name of the ROM you are running
SETTINGS: the kind of settings you applied to your kernel (example: Governor=interactive, Scheduler=Sio, Multicore Power Saving=2,CPUquiet=balanced, LP Core uV=-15 mV, MPU uC=+20, and so on)
GOOD: the benefits you experienced with your configuration (the more specific possible)
BAD: the badness you experienced with your configuration
Of course, if the thread begins to grow up, is recommended to read everything before posting a configuration too much similar to another which have been posted yet.
If you think this is a good idea, press thanks, if you want, and let's begin posting, otherwise report it to moderators, like @laufersteppenwolf, and they will close this thread as soon as possible
If someone like @JoinTheRealms is interested to, I'd appreciate very much to create a section dedicated to the scripts, as a second post of the thread, maintained and refreshed by the author.. Let me know, and take your own space here, if you think it's good for you!
So, I'm starting posting my own last configurations:
1)
KERNEL: iodak v9.95
ROM: Beanstalk 4.4.2
SETTINGS: Governor=interactive, Scheduler=Sio, CPU max speed undercloked to 1300 Mhz, CPU max screen off frequency=370 Mhz, Multicore Power Saving=1 ,CPUquiet=balanced, LP Core uV=-30 mV all frequencies, MPU uV=-75 mV all frequencies
GOOD: this configuration improve battery life, without decreasing overall smoothness - suggested to the users who don't mainly use the phone for hard gaming and want to find a compromise between battery durability and overall performance
BAD: some little lags, here and there, randomly happen - I suggest to apply underclock, before changing cpu freq voltage, because this configuration is good for 1300 Mhz undercloked device, but it may cause system freezes on some cpu variants, if you set cpu clock up to 1600-1700 Mhz (tested)
2)
KERNEL: iodak v10
ROM: Beanstalk 4.4.4
SETTINGS: Governor=interactive, Scheduler=Sio, CPU max speed undercloked to 1300 Mhz, CPU max screen off frequency=620 Mhz, Multicore Power Saving=1 ,CPUquiet=balanced, LP Core uV=-100 mV all frequencies, MPU uV=-100 mV all frequencies
This configuration is very battery friendly, more than the last one I was using on iodak v9.95. Nothing is slowing down, btw
@JoinTheRealms reserve a post to yourself, if you liked my idea to dedicate some space to scripts explaining

Lol, I'm using almost the same config.
Kernel: Iodak 9.9.5
Rom: Beanstalk 4.4.2
Settings: I haven't changed anything
Good: Very fluid and stable
Bad: battery life, Antutu 3D test score
Sent from my LG-P880 using xda app-developers app
Kernel: 9.95
Rom: CM11 official
Settings: Max Frequency 1150 Mhz Cpu governor:interactive
mpu undervolt -100 on every freq (cpu variant 2, some hangs while waking the smartphone and I need to tap on the screen sometimes, if I press the power button the device won't wake up anymore until I restart it).
Congestion: westwood
Cpu quiet: runnable
Cpu max screen off freq: 475 Mhz
Good: less heat, more battery life, smooth experience
Bad: If I put 1300 Mhz as max freq the battery life will decrease.. And without 1300 Mhz as max freq I feel like cutting this smartphone's cpu potential.
Still bad battery life even with these tweaks, still disappointed, but so far this is my best configuration with Cm11 official.

The scripts i posted earlier, really shouldn't be take too seriously, mainly because they are written for ubuntu and require input. But when i get some time ill modify my post and give some examples of init.d scripts, or more specifically, the commands inside them. That should be somewhat more helpful i guess

Kernel: Optimus Play v2.53
Rom: CM11 official
Settings: Max frequency 1200 Mhz (sometimes I tried to put it at 1100 Mhz or even lower, 1000 Mhz, resulting in better battery life)
Congestion: cubic (since there's no westwood implementation in this kernel)
Cpu quiet: not implemented (I think it's put on runnable or balanced as standard)
Cpu governor: interactive
Multi-core battery saving: 1
Gpu frequency scaling: on
Good: awesome perfomances, the games and all the apps are very smooth and compared to the earlier configuration with iodak v9.95, this is very much better, but be aware that I'm trying to have perfomances and battery life balanced, and on iodak v9.95 I undervolted the cpu of -100mv resulting in some cases of hangs and crashes. Battery life is still good, but a bit worse than the iodak configuration.
Bad: Battery life's not very good, it goes harder on deep sleep when the display's off, iodak v9.95 is the best with deep sleep; in fact it takes a while before entering that state, it usually stays on low frequencies but it still consumes the battery.
An other aspect I noticed is that even when the smartphone is on charge, when I'm using it, it doesn't charge much, if ever it looses energy, which is explained by the very good performances of this kernel.
A small bug present in this kernel, and not in iodak, you usually need to double press the power button to wake the smartphone, but it's much better than risking to have your smartphone crashed while waking it up.
Overall: A very good kernel for performances, I don't know if it's the best but it's very good, battery life's "good" if not using the smartphone, otherwise it drains quite fast, I think faster than the undervolted configuration with iodak.
If you're looking for smoothness with games and apps I'd suggest this kernel, if you prefer battery life I'd suggest iodak more, but I remind you the hang problems on it if you decide to undervolt up to -100mv.
I tested both kernels with the same Rom and apps and use more or less, so I'm quite positive it's a good test.
I hope it helps and you can give us tips or suggestions to improve this smartphone's battery life, without losing perfomance. I think this is the thread's goal.
and yeah, every LG Optimus 4x hd possessor's dream is to have a good battery life so well, let's help each other and get the best out from this device, it's not **** yet in my opinion, it just really has a bad battery usage.
@KrisJoe Very good review! I hope many people will follow your example..comparing user's kernel usage and customizations is the better way to help everyone to find the needed configuration, and to let them make whatever they want, with their phone, on the best possible way

I just noticed something going back at iodak v9.95 to try peppe's configuration; on iodak v9.95 the temperature of the cpu is higher, there's a difference of at least 20° C more or less. Problem was that I went back to iodak because charging with optimus play v2.53 was a pain since instead of charging it wasn't. (Of course I mean while in use)
With iodak charging is flawless (I activated the fast charge option, which isn't present in Optimus Play).
Is it because of the fast charging option that's making the difference?
I'n trying the cpu undervolted by -75mv MPU and -30mv LPU, and it seems a bit laggier than the optimus play one, I can feel the difference just typing with the keyboard on the browser, but it's charging despite me using the smartphone.
What do you think it's the cause of the slow charge in optimus? And maybe more important thing, how is it possible that the cpu has a 20° C of difference between optimus and iodak but I keep the same frequency? I even undervolted with iodak, and in theory it should be the opposite situation, with iodak having lower temperature.

So, talking about charging, on iodak's kernel you have to consider two situations: if you are charging through USB port, you may experiment slow charging and battery consumption even while charging, if you use the phone in the meanwhile (so, using fast charge solves the problem, but it is recommended to do not use it too many often, if you want your battery to have a longer life)..the problem doesn't exist if you charge the phone through AC adapter, so the phone should charge at a normal speed, even if you use it, whit no fast charge necessity.
Talking about my configuration, yes, you may have some little lags, here and there, 'cause this is a battery saving configuration, more than a gaming performance one..
Finally, temperature: maybe the difference between the kernels is due to a different overall cpu voltage, or the temperature is not really precisely shown, honestly I don' t know for sure
Sent from my LG-P880 - Beanstalk 4.4.2 - Iodak 9.95 kernel - using XDA Premium 4 mobile app
I'm using the ac adapter and with optimus play charging was a bit hard and slower than with iodak. With -75mv it seems I don't have problems with waking up the smartphone and it seems a bit smoother, maybe a placebo effect, but I think that it could be the limit of undervolting with variant 2 cpus.
Now that I didn't use the smartphone for while the temperature is lower (49-51° C), the high temperature was due to the 1500 Mhz used at the beginning because I deleted cache and dalvik before installing iodak again (to avoid problems). Let's see how it behaves in these days, but I'm a bit confident iodak's config is better for battery saving, even though with antutu benchmark I did 13000 with iodak and, and 12800 with optimus play (with battery saving and performance balanced). It may be a wrong test but I still wanted to give it a try.
Yep, I tried to uV MPU frequencies at -100 mV, and it freezed my phone, after some seconds or minutes..so, I also think CPU variant 0x2 has this uV limit..maybe it's possible to uV a bit more single frequencies, without causing freezes, but I had not the time to try to individually uV any single frequency

I was thinking that we should specify what runtime we're using, if Dalvik or ART because I actually felt some differencies. What about you? Do you feel any difference with using one or an other? Sorry for the off topic, but I thought we could talk about the runtime also since we'll looking for the best performance/battery life.
O.T.: Don't activate ART Runtime on the latest cm nightly (3rd of April 2014), it will force close some apps like uicall, dialer, ecc. I had to return to dalvik by installing an older version in which ART was working... quite unconvenient.
This is the best thread ever guys.
I am using iodak 9.95 in Zaiben RC8.

The only bad thing is that if i want to wake a the device it doesn't wakes for the first time and I have to press twice the power button.

Yes, everyone is free to talk about ART or Dalvik, of course, it's related to Rom customization, using or not using it! Personally, I'm not using ART, considering it's on an early, experimental stage, and I have no time to switch between the two runtimes, if something should go wrong with ART (I need this phone as my really daily driver, and I haven't too much time to experiment, ATM).. But every single accurate review, also explaining how runtimes work, with a specifical kernel and a specifical Rom, is appreciated here!

Try multicore powersaving=1, and a little undervolt, you should have benefits in terms of smoothness, without losing battery

KERNEL: Iodak 9.5 (I know 9.95 is newest but I prefer 9.5 as I think it's performance/battery ratio is better.)
ROM: CM 03/30 nightly
SETTINGS(variant1): CPU max: 1500 lowest freq.: 620 screen off max: 475. GPU freq max: 564 mhz
MPU undervolted by -122 mV and LP core undervolted by -10mV but lowest freq. voltage is on default and max freq is on 1230 mV due to 564 mhz GPU freq. ART enabled and Multicore powersaving is set to 2.
GOOD: A lot smoother than 9.95 and with these undervolting I've done, it can survive heavy gaming without throttling.I can say this setup is the best for gaming if you've got variant 1.
BAD: Battery life is a bit worse compared to stock kernel.But with ART enabled it's difficult to notice the difference.Plus if you underclock to 1300 mhz your phone will still be smooth while giving you better battery life.

I use volume rocker to wake the phone up as a workaround.Easy to reach it with your midfinger once you have the phone in your hand.Plus you get to press the power button less, extending it's life.
Edit : Incase you didn't know official CM and most of the custom ROMs have volume rocker wake option in settings > button or under some other category.
hello guys .... I ask for help because my LG 4X HD gets hot during the games, with any game, I tried to set 3 cores 2 cores 1 core, but continues to heat up too much ... you can suggest me a rom or a kernel who do stay cool LG 4X HD? or you think it's a hardware problem? Thank you very much.
Setting number of usable cores won't help much, what you need to do is to underclock and/or undervolt. Also other than stock kernel can reduce the overheating.
currently use original kernel 20d but continues to overheat ..... how do I set the undervolt correctly? thank you very much
You need root acces and Trickster Mode - aviable at GooglePlay.
Also it depends on the kernel, whether if allows under or overvolting. If I recall correctly, you can't undervolt on stock kernel, but you can underclock, which will definitely help to keep the phone a little bit cooler
I already tried to set to 1000 MHz, but continues to heat up .... which kernel do you recommend that less heat and can do the undervolt? thank you very much
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.

nice to have some feedback from someone that tested=p. what about hotplugging? Today i disabled hotplugging and had always 4 cores on and it does not seem to be wasting more battery than with hotplugging enabled

totally forgot about bedalus experiments!i had a Nexus S at the time and saw that post, but back then i didnt mess around with anything on my phone so i completely forgot=p.thanks!
The only thing he doesnt adress is hotplugging(the Nexus S was single core so he couldnt even if wanted=p). Anyone care to shed some light on hotplugging?is it really worth it or there are minimal gains?

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.

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.

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.

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.
