Is it possible to overclock LP core? And use only this core for small tasks as Web Browsing or WhatsApp?
[LG Optimus 4X HD] wajahebat:
From my previous One X machine, it is possible to control the LP Core ( Low Power Core ) but there is still no people intend to overclock

the LP Core, most people are concern to power down/reduce the usage of main 4 cores, and only use this LP core or 5th core to run at all time as it uses only small amount of power...

But it is reported unstable, most control can be made through kernel management...Even right now i undervolt all my LP core...
[LG Optimus 4X HD] Ananasnonym:
This is exactly what I want to do. The overclocking is just to have enough speed for more tasks.

How can I just use the LP Core for more (or even all) small tasks? Is this core even activated in this kernel (because trickster mod shows only 4 cores)
[LG Optimus 4X HD] @non4:
Yes trickster will only show 4 cores, the LP core will show as "deep sleep" and maybe 51mhz in stats ;)

Sent from my smart frying pan (Tegra 3)
[LG Optimus 4X HD] Ananasnonym:
OK so it is activated, Thanks :)

But how can i control it in the way, that it is used more (for small tasks)? Even with conservative or powersave governor the cpu monitor says it uses 720 MHz instead of LP core ..
[LG Optimus 4X HD] wajahebat:
That would be such a waste, do bear in mind that this miniature 5th core is used as a low power core during screen off or when your system

is idling at most, deep sleep, to maintain your data running...If you overclocked this core means that you will loose much more juice(battery) during screen off, battery drain will increase even during deep sleep...

As in you intention to disable the 4 core and only run LP Core, this LP core will not be able to run even such small task...Think wisely, i would avoid this as i want more batterylife rather than more power in terms of performance...

It would be better to maintain LP Core position, and just play with your 4 cores, either undervolt or underclock the frequencies...
[LG Optimus 4X HD] dimi89:
Or maybe he can completly shut off 2 cores and run his phone just on 2 ?
[LG Optimus 4X HD] wajahebat:
That should be the idea, and most people preferred this way...

Shut off 2 cores, runs only on 2 cores and overclock it to 1.7Ghz, that would be better:D
[LG Optimus 4X HD] dimi89:
Why overclock ? I think 1.5 GHz whould be just fine even for some small games...I personally dont like to play with overclock and undervolt options...
[LG Optimus 4X HD] @non4:
I see why people are paranoid about buying apps on android, I've had a few wasted purchases myself. Quake3droid just disappeared, and Gameloft games lag on my quad core phone more than they did on a desire s???? But if it works I always buy it, otherwise it gets uninstalled. But don't talk about it here, even if you use warez in the "right" way its against the rules. Google needs to enforce quality control, if they did Gameloft would be out of a job!!!

Sry, but for me in stock version mobile data doesnt work. After booting I get "H" as Umts-connection, but no connection possible. If I try uncheck / check data, the display of "E"/"G"/"H" alters for less then a half of a second with black (no sign for connection type displayed) and so on, no connection would be established...

How I can change the min_cpus? With Root Explorer I haven't the permissions to edit it.
[LG Optimus 4X HD] iodak:
Just edit with rootexplorer. It is r-r-r but you can change it.
[LG Optimus 4X HD] Ananasnonym:
Oh ok I thought LP Core can do up to 513 MHz. If it is even THAT low powered I see your point.

I wanted to use the Low Power core for all tasks that would require 760 MHz or less and fire up the other cores when needed.

After all, thank you very much for your help - I will play around with undervolting and clocking :)
[LG Optimus 4X HD] wajahebat:
Some people would prefer more performance in while maintaining battery life...

Undervolting the core from frequency below 1.5Ghz is just a fine tune to get a better battery life..

Going beyond 1.5Ghz, is likely cant undervolt as the more power you request, especially over its manufactured limit, the cores need more

voltage...
[LG Optimus 4X HD] iodak:
http://www.nvidia.com/content/PDF/t...ecture-for-Low-Power-and-High-Performance.pdf

Read this to make things cleared. And way there is no point in OC lp core. Nvidia knows when we should change to G cluster (when lp power consumption exceeds what would g consume on same speed).
[LG Optimus 4X HD] Ananasnonym:
Thank you iodak - this document explains things veery well :)

Hi folks,

whats the instruction for installing this on CM 10.1.2 ROM ?

just put the iodakX3_v07CM.zip on intenal, go to recovery and flash from zip? anything else? do i need to wipe cache/dalviki ?
[LG Optimus 4X HD] amkirk94:
Yes, you probably want to wipe cache BEFORE flashing the kernel, but that's basically the process! :D

Hey guyz, how is deep sleep with this kernel? with CM kernel i have very bad deep sleep time !! like after 4 hours withouth activity i have just 2 hours of deep sleep, the 2 remaining hours the phone isnt deep sleeping. HELP !
[LG Optimus 4X HD] arnookie:
Iodak Will it be possible to leave gpu and cpu speeds like you did in V6 so we do not have to manually change them to overclock?

Also did you figure out why max overclock was lower in V7 than it was in v6 in stock rom? Ie could set cpu to max 170000 with V6 but with V7 only 150000 was max. Thanks for a great Kernel but I'm sticking with V6 because of the problem above.
[LG Optimus 4X HD] TheFerhatKing:
I'm using v07 of this kernel and have a problem, I'm on stock Rom: I can't change the brightness. If I change it from 90% to 50% it set the brightness back to 90% and the screen timeout is everytime at 15 sec and I can't change it. Hope you can help me.
[LG Optimus 4X HD] alberteske:
I do not think it's related with the kernel.

Reflash ROM + gapps + Kernel and wipe Dalvik Cache
[LG Optimus 4X HD] TheFerhatKing:
I did it no change.
[LG Optimus 4X HD] arnookie:
Wipe data, format cache and wipe dalvik then fix permissions. Reboot and go to app settings. delete data on all apps.

Worked for me and I could change brightness again. but I would suggest usin V6 as V7 gave problems for a few of us on stock rom.
[LG Optimus 4X HD] profyler:
can we install OTA updade from Cyanogenmod normally after changing its kernel to iodak , or do we need to do something first?

Hey Iodak, thank you for your great KERNEL. I would like you to take a look in one specific kernel wackelock:

The wlan_rx_wakelock. I have this problem until LG pushed the 10f stock firmware (where on its changelog had "improve wifi during sleep"). After that firmware, this wackelock was gone. I was pulling my hair off before this, I did google the entire world and noone with this problem had a solution besides tips that didnt work at all.

When i ping my phone (CM+your kernel) it answers me instantly. But on ICS 10f/h firmware it always answered me after a while. Thats because the wifi was sleeping and will wake up from time to time. This also happens testing in my iphone/galaxy s2. I didnt test it on 20a stock firmware to determine if it is a rom or kernel thing, but i might guess kernel. This is also discusse here: http://xdaforums.com/showthread.php?t=2133176

I actually find interesting that im the only one complaining about this here, because it drains battery heavily.

sorry to bother you, but it would really be great if you could take implement whatever Lg did on 10f firmwares...

[LG Optimus 4X HD] profyler:
yeah i saw that thread but it was useless for me, buying another router is not possible, and anyway, there are times that i dont have anything conected to my router except from my phone, so in my case its not a "network traffic" problem. i didnt have this problem on ics one day before i flashed CM, so i dont think its something that is not the rom or the kernel itself.

did you leave your wifi set to "always on" on advanced menu? did you do anythink else?
[LG Optimus 4X HD] Navios92:
I have this problem too and I don't know what to do about it.
[LG Optimus 4X HD] abhi08638:

[LG Optimus 4X HD] profyler:
must be a JB thing then. i always had only core 0 at 475mhz on idle.
[LG Optimus 4X HD] iodak:
Probably app is not doing reading right. Of it goes below 475 then it uses LP core. Check your cpu stats.
[LG Optimus 4X HD] profyler:
Thanks, do you know if your kernel changed the value on minimum cpu frequency? when you go to about, performance, cpu. I have minimum at 750mhz

shouldnt it be 500Mhz since our cpu goes from 500 to 1500 ? or is it a CyanogenMod thing?

do u know?
[LG Optimus 4X HD] tonhao12:
You must set minimum cpu frequency to go lower than 750 mhz....and actually its minimum frequency is 51mhz...you can select it in this screen you are posting here.
[LG Optimus 4X HD] iodak:
That is input boost driver. It rises min freq to 750 on input events (to eliminate lags).
[LG Optimus 4X HD] ALuedtke:
Hi iodak,

now I had time to test the audio glitches also on a different rom. I used your CM v07 kernel on the stable CM 10.1.2: I had also some audio glitches with screen off (I used th Apollo Player.

[LG Optimus 4X HD] profyler:
But this is something that your kernel did?? do you know what value should it be if it where stock? i want to change it to stock.
[LG Optimus 4X HD] iodak:
It was also on 750 but only on interactive governor and only on touch. Now it registers every input on keys, touch, game pad... And independent from any governor.

You can change parameters in

[LG Optimus 4X HD] tonhao12:
Somebody correct me if I say something wrong, but, my understanding is that RAM is managed by the OS not the kernel. So the problem you are experiencing is due lots of apps and system resources being used at the same time, so, when you open a app that demands a great amount of memory system may free some memory by killing some background process (apps). Then when you return to this killed app it will have to be reloaded. The fact that the app appears in the "recent apps" doesn't mean it will be always paused and can be brought back from the point you stopped it, system may have killed it silently to benefit other apps.

[LG Optimus 4X HD] iodak:
That exist on stock rom. They are doing it (i think so) by setting sysfs parameters preview and recording. I think some service or something is setting them. Also different min, max clocks and cores are set when you do hi res recording, (this part is done from driver) to eliminate lags. I will see if it is possible to do it all from driver. None of this is working on CM roms because preview or rec bool are never set to 1. Sorry for bad english. I hope you understand what i am trying to say.

I installed iodak v7 today, switched to it from eternity project kernel.Even though people say eternity project kernel is battery friendly and iodak is good for gaming, I felt lots of lags playing these games after installation : Ironman 3, Real racing 3

do you guys think it has something to do with cpuquiet governor? I only changed the cpu governor to interactive and turned smart dimming off.EA & gameloft games are famous for their badly optimized games, so if I would change cpuquiet governor to balanced or userspace, would it help? Any ideas, other recommendations?

I also overclocked GPU to 520 mhz, I didn't change CPU clocks since my tegra variant is 1 and I already seen temperatures between 75 - 78 while gaming.Eternity project kernel only had GPU overclocked to 584 mhz as default, though it didn't produce heat as much as iodak kernel

You should at least try to change cpuquiet to userspace. That should improve performance at least a little bit.
