Can anyone help me to enable my phone's all 8 cores
Because when i check Kernal it shows only 4 cores working and the other 4 are offline

All cores are working it's just the apps like kernel adiutor don't support this cpu correctly and don't recognize the other 4 cores

There's no app that fully support our cpu "probably no dev cares" but if you want you can check out "Cpu stats" app which can show the cores usage in % but still can't show the frequency. At least it will make you feel better knowing that all cores are active in heavy usage

Yeah i think the 4 cores are able to handle your normal use
So the other 4 are offline or not working
i have queation too but other problem is, i wanna know if i unlock bootloader and nothing else will my phone work? And will that step allow rooting with super su and can i install twrp? i mean without modifying kernel

Like others said they are most likely still active, though deactivating them or activating them doesn't make difference in performance(or if it does it's much less than expected).

Hey guys I have my nexus 7 OC to 1.6ghz? MIN and MAX. It runs on 60C is that too hot? I'm using motley's kernel 520mhz GPU ?

its a little warm, but normal for 1.6ghz if youre using the device.
What is considered too hot? 70C ? I do have a gaming PC and do the same rules apply to what is considered too hot? For me 80C is too hot for my GPU on my PC. Is it fine to have the same mindset when it comes to my N7?

stock thermal throttle is 85C(some custom kernels set this higher or lower). at that point the device will lower the cpu speed to cool itself off. safety shutdown is at 100C. if at 1.6ghz, and gaming, its probably normal to go into the 70C's if its a cpu intensive game. it also depends on the outside temp, the cooler its outside, the cooler the device will be.
Any way to revert back to the stock kernel settings? I reflashed the Stock kernel for the nexus 7 but i want to know its governor and voltage and etc back to full stock settings.

if you didnt change anything, it would boot up at its default settings. or if you have set something with a cpu app to boot, unset it and reboot.
Thanks. I wanted to do a comparison of different kernels and see which fits best for my everyday usage.

depending which kernel youre using and what temp the thermal throttle is set for. you can even remove tbermal throttle when building a kernel, but the phone would just shut down when reaching the safety temp.

Can someone please explain to me why none of the kernel's have OC ability?// I think it's due to quad core overheating but I'm not sure and would really love an actual explanation.. Thanks
Sent from my Nexus 4 using xda premium
they all started with OC ability right at the beginning, then .. a good few number of people had HARDWARE bricked devices, that had a fault with the battery no longer being connected or something
they all had overclocking in common, since then , its been removed on most or all kernels
I'm sure that as time progresses it will be made available again. What's the need to clock anyway its fast enough as it is

This is true, its a 1.5ghz quad core lol why do we need more ?
Also what was happening in some kernels was that mpdecision (which is qualcomms code that says when the cores should be on and offline, i.e hotplug) was using the hardware maxs of each kernel, so if the kernel was capable of going to 1.8ghz, even if you set the max to 1.4ghz ( using software) , mpdecison would override the software and use the hardware max.. therefore.. .it would ramp all cores up to 1.8.. which caused a major cluster ****..

Will I certainly don't need it. Would it be nice to have? Yeah but it isn't on the top of my priority list.
What he's saying about mpdecision is true. If you read the change log for Franco kernel he removed mpdecision and is working towards a open platform for kernels. So we should hopefully be seeing more goodies.

So I have a very thought out question now I have a 4 core phone right? Well my battery life is below average and I was wondering if I had all my cores running at once would it balance out battery life? I just need some help from someone who knows about all this and are all cores mandatory?

You can select how many active cores are activated with trickster mod and (necessary!) a kernel that supports this.

I know how to and can with my kernel but I need to know if more cores are activated if the battery life will be better or worse

I would definitely take a look in to what my batter usage is and how to control that before I worry about the cores. Just my two cents.
P.S. I am sorry but I believe the Multi-core in the title is spelled wrong.

More cores active would mean more processing power, and more processing power requires more energy(atleast on the same cpu), so disabling most of your cores would result in better battery life, maybe by a little bit though.
Hahaha I didn't realize it said mulit
Sent from my Optimus G using XDA Premium HD app
useful topic
It seems to me that by disabling cores wont make a difference to your battery life, only to your performance. It doesn't matter if 2 cores work for 5 seconds or 1 core works for 10 seconds, it is practically the same power consumption
Play around
I would say download CPU-Z from the Play Store and look how much Cores are active and which clock they're at.
Then flash a custom Kernel, which lets you control the clock, govenor and how much cores are active, undervolting may increase your battery life too.
Play with the settings (PLEASE DO NOT RAMP UP THE CLOCKS or set the voltage to the lowest point you can, it may break your phone, stay reasonable, it's not my fault if your phone bricks) and look what's best for you.
Pro Tip: Take a look at the different govenors and look what they do. Google them!

I hope I could help you a little
Im using trickster mod and I know about all of this I studied up and have undervolted by 200 MV stable but I'm using the hotplug settings to 1:2 so not all 4 cores are active and I get almost two days on one charge!so I guess that does mean less cores use less power

It's octacore, with the correct governor and while performing a heavy task, every core will be activated

The cores are activated by the kernel, not by an application (it can communicate with the kernel tough) , if the kernel deems it necessary, it will activate them.
And what's happening to you is that the kernel thinks that enabling those cores is not needed, so it turns them off to save energy

Octa.
Now I must say..it is really octa core..thanks for sharing infos..
I would like to know if someone that is running stock ROM with Stock kernel and rooted to check what the governor and governor settings are
So, I have an Amazon ads enabled G4 that I got from a friend. While using CPU-Z I noticed that, at least what the app shows, is that four cores are always on, and two more turn on as needed. While the four that are always on are clocked at 1.21 gHz... We'll call these four "battery efficient" cores, it seems the other two that turn on as needed are clocked at 1.44 gHz or the "power" cores. At least for me, there is a total of four "power" cores but the extra two never come on.
In an attempt to save battery, I turned on the android battery saver on. With this enabled, the "power" cores turn off and do not come on at all. The four "battery efficient" cores stay on and what a difference between battery saver enabled compared to battery saver disabled. I also noticed all of these eight cores to have a minimum speed of 806 MHz.
So, I've been able to achieve over 6 hrs of Screen On Time. I could only dream of when I used my Moto X Pure Edition. I'm trying to figure out why the 808 while based off A53s does not achieve said Screen On Time, while a far inferior processor is able to do this with no problem.
Obviously I cannot root the phone to check it myself. Anyone care to discuss?

I'm not rooted and I can't load the app right now but can't you see the settings even though you can't change them on a non-rooted phone?
I've tried, but I have not found a way or an app that shows the actual governor parameters settings. It only shows what governor is being used. @Tel864 do you know something I don't???
Anyone else that has their g4 rooted please help.
