Lucky you. I installed thumb keyboard just to test but it gave lag while typing. Oh well. I'll adjust to 1242 when I get annoyed. ^^

Can someone post default values for governor adjustments, please? I tried loading defaults but it seems that section didn't change, only general part. Even voltage did not return to default. :D I only want to revert some on stock values. ^^

Still best kernel for S4 :)

Thanks ktoonsez! Perhaps you can change the sliders from ktweaker to + and -. Still hard to slide to the right one sometimes. ;). Just a future wish. No hurry. ;)

Clear data for the app, in install it... reflash the kernel and you will be at defaults... but if you have to do all that it's a sure sign you have a conflict somewhere

eyo KT, your kernel is the best atm bro! i got a little suggestion. Is it possible to implent a Zram option into kernel app, where you can choose the Swap and Zram size ? This would be awesome.
[Galaxy S 4 i9505 Original Android Development] rlorange:
Use my Turbo ZRAM app ;)
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
If you can test it I can do it when I get a chance, I tried it quickly the other day and it never loaded with standard zram sysfs files by doing the simple insmod with no parameters.
[Galaxy S 4 i9505 Original Android Development] rlorange:
Oh really? You might need to

swapon /dev/block/zram0

When I do this it auto loads the standard 400MB zram
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
If tried a few times and no luck really with the +/- buttons. Its not a coding issue, but a layout issue, I hate java sometimes. What happens is as soon as I put a clickable object with a slider I loose the slider functionality which kills the math to set the right value, its a catch-22 screwage.
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
Let me know if you have time to load up a CM ROM and I can build you a test to see if you can get it working, I will leave ramdisk alone (like TW version where I have NO insmod) and let your app do its thing. Let me know.
[Galaxy S 4 i9505 Original Android Development] rlorange:
Ok might be a while. Someone already on CM 10.2 might be able to test? IamnotKurtCobain?

Any ideas how I can resolve it?

For those using TW kernels who want standard zram 400MB script set and don't want to use my Turbo ZRAM app or it didn't work... I made a CWM zip which will set an init.d script to run.

[Galaxy S 4 i9505 Original Android Development] donalgodon:
Just to follow up, even the stock CM kernel goes down to 1816 on 8/29, so it loses 5MB somewhere.
[Galaxy S 4 i9505 Original Android Development] iamnotkurtcobain:
Some buffer I guess. Phone seems snappier now! Smoother too. So it must be some gpu mem.

Misflashed

Hi there, folks!

I have wrongly flashed AOSP kernel on a Google Edition Rom (it is still TW, not AOSP) and now I'm stuck in a bootloop where I can't even acess the recovery mode.

Does anybody have the .tar kernel (TW) so I can flash it through ODIN?

Txs in advance!

Hey man, a friend of mine, kind of programmer is showing me some stuff about compiling in ubuntu and we (I would be more appropriate :p ) decided to use your sources to build a test kernel so I can play around a bit, see what's under the hood and other silly stuff. :) (I've always wondered since my i9000 but never actually tried going deeper)

Anyway, I was wondering when will the latest sources be up on github? (if not up already)

Thanks. :)

what should GPU voltage be set as? under Low Nominal and High?
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
Start with - 25 across the board, run it for about week and if all appears to be stable then UV another 25 and so on until you've found your sweet spot.

nvm got it, needed to hit menu and load default and then reduce by 75 thnx
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
Guess I just misunderstood your question then. Thought you were asking for a recommended set lol but yea you definitely do need to load stock table or the sliders will revert to 1mV.
[Galaxy S 4 i9505 Original Android Development] crnkoj:
I did - 150mv first like ktoonsez has in his settings, tested it and worked so I went to - 170mv on all steps, still testing it, but it seems to work fine, and the heat produced is certainly less than stock volts. Not sure if I want to lower it more though, as it already has the desired effect while stable.

Btw the latest kernel is great for cm10.2 based roms. No more laggynes/choppiness with ondemand governor for gpu, so no need to use simple as it stayed at max for me ask the time in earlier version. Performance gov however seems to be bugged, as the freq is stated to be max (450) in my case, but it's laggy as if it's stuck at lowest speed (128).

"sync_extra_cores"

Is this an efficient way of working in Ktoonservateq for all the cores?

Will this also results in a better bettery life when this is ON?
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
It won't affect your battery much. The other tunables are what will determine that. This option doesn't bring all cores online. What it does is it only boosts the Mhz on the cores you specify to come on with the touch_boost options at the very top of the adjustments section. So no extra cores come online at all. This just sync's the ones that are currently online.
[Galaxy S 4 i9505 Original Android Development] ramon.nmgn:
Thanks you.

I am using your settings now again (i switched alot from rom to rom these days with different kernels).

Eventually i always come back to Omega rom with this awesome kernel. Seriously, this kernel is really smooth and stable.

I only have one question, when i apply your settings (@LuigiBull23) everytime i open the Ktweaker app it says that my I/O sheduler does not match my saved settings, and if wanna apply my saved settings. It looks likes the settings in the I/O adjustment don't stay there. Do you know if i can solve it by myself or whats going on?
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
After applying the settings just answer "No" for all questions then exist and reenter Ktweaker and you should be good from there. They will stick.
[Galaxy S 4 i9505 Original Android Development] ramon.nmgn:
Well, they stick, then i restart my phone, open the ktweaker. At that point no message popped up so far and your settings where still sticked. I close the app again and play some things with me phone and reopen the app again, and that annoying message pops up..

So i can apply your settings, reboot and reopen the app and everything is still there. But just like i said, it happens after some minutes. So when a few moments later i open the app again, the I/O settings are gone.. pretty annoying. But i will keep the I/O settings stock then at this point.

May i ask you a question, for what reason did you edit the I/O settings? Is it speed? Stability? Battery?

Thanks for the good help so far.

And ofcourse thank you ktoon for this kernel:)
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
Something else must be interfering with my I/O settings then. You likely have an app or some script conflicting with Ktweaker causing the settings to not stick. Do you have anything such as Trickster or Crossbreeder installed? Those will definitely cause problems and I would uninstall them if they are currently installed. Also, make sure "lock frequencies" is checked on and that screen off scheduler under Extras is the same as selected scheduler.

The ROW scheduler gives off higher priority to read operations so my adjustments were made to slightly improve write operations by increasing write requests as well as reducing starv limits to ensure read queues complete their process early for writes to come into play sooner.

[Galaxy S 4 i9505 Original Android Development] ramon.nmgn:
No no additional apps installed that can do this.

I even completely reflashed omega v10 and flashed the kernel again...

Still no luck. However, maybe omega uses some scripts that overwrites the ktweaker i/o settings?

Can it be that it has something to do with fix permissions or do you say that is does not have any influence?

Thanks
