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

How do I know that both cores are working and activated ?
Is there a program which reports processors status ?
Thanks.

Core 1 avg usage - 43%

does android useage of the cores is so bad ?
So why do I need 4 cores when even the seconed one is used so poorly ?
Or is there some kind of magic kernel switch which makes the cores usage more equal ?
Running on kingdroid v2 ROM trying several kernels.
Thanks for any info

You should ask for the kernel in another post so the question will be probably read by more people...
I don't think there is a kernel like that btw but it would be interesting to try something like that

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance
Cheers

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?
Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic
IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.
I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again
Cheers
Corey
Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?
I go to 1.6 but use the Trinity App to go back to stock when OC not needed
Sent from my GT-I9300 using xda app-developers app
I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.
iam just want to know if my device normaly or not....
my notice about my device get little warm on front up area of screen

N900 is octa core variant. Means it has 8 cores of CPU and its a heavy hardware. Its normal for your device to get heated.

Dear devs and users, I want to know whether Ultra Power Saving Mode presented in S5 is Software dependent or hardware. . ??
As far as of my concern, it is software dependent. . If so, can it be ported to S4 Sock KitKat 4.4.2 ??

Is there a way to put this on the att SGH-I337
Hy guys new to this forum
i recently purchased SM-G7102 (dual sim) . Once going through the specs i noticed it shows just 890 mb of total ram in apps and cpu-z whereas it's written all over it has 1.5 gb ram. I really don't understand why is it so. Checked thoroughly for counterfeit or clone but i guess it's original Samsung device and getting oficial software updates too. Stock samsung pre installed apps are working fine just this issue of ram is bothering me.
Any help and advice will be much apreciated.
Thanks.

Only 865 MB instead of 1,5 GB RAM?
I checked the RAM of my SM-G7102 (Grand 2 Duos) with CPU-Z, version 1.26. Only 865 MB of RAM is displayed.
Is this correct?
