No ok.. first.. thanks for the explanation.. i found an arm white paper witch talks about powergating on big.little

And, for all, it's quite simple.. when system doesent need some part of the core, powergating shuts down it.

Easy simple.. no hotplugghing since there arent unplugghing, core are always "on" and the parts not used are not alimented..

better than asincronism of qualcomm!!

2) i'm using a note with perseus kernel.. and andrelux is so geek, never ever had the possibility to change body bias of the transistor.. it's fu**ing good!

So, i'd want to know more info about exy, since, new note3 will have it, and the snap too, but, with those revelation, is better the exy than snap for the power usage!

That's why..

P.s. who has the s4 exy? How many screen on hours could you do in one day?

Tried it via STweaks and the phone is now restarting as soon as it starts....:(:(:confused:

Any solution to restore??

SOLVED! Reflashed Kernel via CWM :)
[Galaxy S 4 i9500 Original Android Development] alawadhi3000:
Every device is different, you have to find yours yourself.

Try -50mV on the A15s and -75mV on the A7s as a start and tweak from there.
[Galaxy S 4 i9500 Original Android Development] vinandy:
Damn! n i thought that all OCTA phones would be same. :crying::crying:
[Galaxy S 4 i9500 Original Android Development] skivnit:
I only uv low frequencies on the a7 by 25 however whenever phone is locked and i open the s view cover while plugging the charger my phone reboots it happens all the time
[Galaxy S 4 i9500 Original Android Development] vinandy:
Same thing happened to me, flash the kernel via CWM / ODIN again. It'll solve this problem.
[Galaxy S 4 i9500 Original Android Development] th3hate:
Do you guys undervolt within the stweaks app, or edit default.profile directly?

Moving the voltage sliders with my big fingers is driving me insane.. why don't we use mv steps instead of uv?
[Galaxy S 4 i9500 Original Android Development] gdonanthony:
maybe im lucky coz i UV my A7 cores -100mV no reboot so far no problem
[Galaxy S 4 i9500 Original Android Development] clavicle:
It is kind of tricky and very cumbersome doing the touch way, I get the job done manually by editing the /data/.perseus/default.profile.

For easy backup and restore of default.profile you can use stweaksprofile programme and get the job done.
[Galaxy S 4 i9500 Original Android Development] mw86:
I have one of those cases and it could very well be your A7 clock... If you overclocked to 750 mhz some of them are just barely unstable. Example if I use it on rare occasion a screen on is enough to crash it. If your getting reboots and not persay a freeze then reboot, it could be volts on your upper A7 frequency only because - 25 mv on most of those is usually fine. Should be fine on 700mhz at -25mv but i wouldn't see 750mhz. Each phone is different handling so you just feel it out. Im on 700 a7 max and no screen on reboot plugged in or not with sview cover or plain screen on. I did however have that on 750 max when i had tried it a lot.
[Galaxy S 4 i9500 Original Android Development] skivnit:
I'm thinking the same it's a shame I can't uv too much and can't use 750 as it's not stable. Guess my chip sux

I'm also facing noticeable lag when scrolling the phonebook
[Galaxy S 4 i9500 Original Android Development] mw86:
Mine handles the same, it's not like your the complete minority in that handling a large amount didn't get that stable enough to not have issues like you mentioned. Your chip is fine. 700 in chainfire was around mid 25k score which is amazing for a low power core. 750 only gained about 1000points hitting around mid 26k max on A7 750mhz, i was able to test that but long term stability wasn't there. So no real loss at all as that amount of points i chainfire is not a noticeable performance difference. Leave it on the 700mhz max and you won't regret it because you won't have to deal with random reboot like I was anymore.

The user that mentioned playing games a lot and had lag on 640mhz. I tried different volts and play same game mentioned Real Racing 3 and was enough sitting on a menu screen for a min or so after a race or so to have the gpu crash... Usually goes very bright with random colors on screen a quick power button hold reboots it fine. So i'm on 600mhz gpu max with no issues showing up at all and as the user mentioned this seems smoother. So I did have the same handling in Real Racing 3 sorry I didn't get message back sooner but I wanted to have proper info to report. So using A7 1.4ghz A15 1.7Ghz and 600mhz Gpu.
[Galaxy S 4 i9500 Original Android Development] skivnit:
Did not try oc gpu as I didn't see any improvement over stock plus I don't want to use more juice as my uv always causes problems

Hi friends...

Im on Omega v10/ Perseus 7.2/Crossbreeder 7/ Xposed.....

I luv listening to music very loud... Ive increased the audio settings using Stweaks.... Ive posted a screenshot of my Stweaks Audio settings...

Recently Ive noticed that when im playing music (JetAudio), music keeps pausing on its own at high volumes... Sometimes it does and sometimes it doesnt... Its very frustrating.... Not sure whats causing it and why???

Has anyone experienced this kinda thing?

Anyway can plz help me fixing this issue...

Nothing mate I have full sensors with 5 accounts ,wifi, data on, as for brightness its set at auto so I dony worry much sometimes its a little too dark I add the extra 5 degrees to make it brighter :)

Other than that its wanam rom 1.8 nothing special neither did I UV my kernel I just raised the speaker levels.
[Galaxy S 4 i9500 Original Android Development] Nasty_z:
I've faced the same thing. Well, it happens when you either increase the Volume to way too high values or increase other aspects such as bass or treble too much. I experienced the music auto pause while using extremely high bass values combined with high volume using Stweaks and viper4android. I had headphones on and this has happened multiple times with various settings that I've changed and tested with.

According to my experience, it's like the phone has a sort of sensing ability on when the sound increases a lot. Perhaps it's included by Samsung to help you from damaging your ears and the phone's Speakers.

Andrei I am seeing news reports of Android 4.3 supporting TRIM commands is this a kernel change or is it dependent on the OS supporting it? Just curious if it is something that could be supported on the kernel level only (for us on 4.2.2) or if there is something within the OS that needs to change for TRIM. Just for fun I am going to run this ADB command in 4.2.2 over the weekend to see if maybe 4.2.2 is calling it :p.

Taken from Anandtech article here: http://www.anandtech.com/show/7185/android-43-update-brings-trim-to-all-nexus-devices

/while typing I realize that this is more than likely dependent on OS support but would still like to hear yours (or anyone else for that matter) thoughts on it. :)

*edit*

Please ignore, found that Android Tuner on the market can TRIM partition on demand or boot. So the OS does support it just that on the Nexus side they made it happen automatically.

All cpus are slightly different. What works for one phone may not nessesarily work for another perhaps just use it as a guideline, then I'd start increasing the voltage on the lower freq. 750mv seems real low to me. Lowest I went was 875mv I think. Stock now is 950mv I believe..

[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I've been rebuilding the kernel tree over the last week or so, meaning I'm building over a clean(-ish; using a exynos-3.4 repo as a base) kernel from scratch and dissecting everything and cleaning everything up that's not needed.

I won't be posting any ETAs but I'm over halfway done. After that we can begin adding features.

The point of this is to not rely on Samsung's source drop. In July the Arndale Octa will be released so we'll get both Insignal and Linaro sources for the 5410 platform to work and cherry-pick from, most likely in even >3.9 kernel base as with the current Arndale board. Better do the work now regarding most of the phone specific additions and have a clear overview of the drivers and what actually constitutes the platform.
