I came across kernel auditor and info says that our P8lite only fou core are in used the remaining four are offline..is there any way to activate the remaining 4 core.?

It's octacore, with the correct governor and while performing a heavy task, every core will be activated
@XePeleato
Yes, but shouldn't kernel aduitor be able to enable all 8 cores.. I tried enabling but it automatically disabled

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..

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 was on the web and reached this site http://lwn.net/Articles/573231/ . Can someone with kernel knowledge explain this? Is possible to get 8 core running on the S4?

as you know it's experimental..the dev is tricking the s4 to think that the device is in power saver mode and performance mode at one time..your cpu will be cook itself if you doing this thing..it is the way to destroy your device,that's it..
Linaro has applied patche for s4 exynos 5410 named edcs ... exynos dual cluster support.... plz developer use his source to make new kernel.
Still waiting but i dont think any1 can do that :v
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?

Wanted to see if anyone is willing to share stock governor settings.

Just need stock governor settings, from anyone that has an unlocked bootloader and has been able to root this phone.

I know it's extremely hard to figure out what the stock governor and its stock settings are, however, I was hoping since we have so many great minds here at XDA that thus would be an attainable request ???

So, if you have a rooted moto G4, would be greatly appreciated if you share them stock governor setting and anything related to the kernel

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.

@bigunwhistle what I'm referring to is any application that allows you to control the governor. Is it better to siwtch to PM in an attemp to not clutter the thread???

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).

Does anyone know of a way to hotplug or how to enable hotplugging for at least the ls997? The mk2000 v1.1 supposably does but its no where to be found. Is there another kernel that does this for this phone?
Searching has not been very helpful so far.
I even tried the commands, but no luck. I do not the core_ctl file that is mentioned a page or two back.

From what I have read, hot plugging is no longer utilized on modern kernels due to the improvements in the interactive kernels

Seems like it would still be beneficial for battery for CPU's to auto shut off when not needed instead of all cores always running.
