[LG Optimus 4X HD] Ajmaldriod:
is overclocking stable?
[LG Optimus 4X HD] Pesach85:
Yes but the temps goes higher than 43 degrees so the screen is very hot, if you set it at 1.5 it goes fine because it's undervolted
[LG Optimus 4X HD] iodak:
Update is up, see second post for changes.
[LG Optimus 4X HD] TheFerhatKing:
What is LG core pluggging power saving?
[LG Optimus 4X HD] iodak:
They limited number of cores running for camera and some other devices to save some power.
[LG Optimus 4X HD] TheFerhatKing:
When I set the cores with Tegra Overclock to 2 the 2nd Kernel never goes offline why? When I change it back to 4 or 3 the cores don't went offline too. After a restart it will be normal but so I can't change the number of cores because when the cores all always on the battery drain will be higher.
[LG Optimus 4X HD] iodak:
Kernel does that automatic. Only if you set cpuquiet to userspace then all cores are online all the time.
[LG Optimus 4X HD] TheFerhatKing:
I know the Kernel does it automatic but only if I don't change the value of the cores.
[LG Optimus 4X HD] iodak:
I will have to buy that app to see what it does. Are sure i it just not reporting right?
[LG Optimus 4X HD] TheFerhatKing:
You can download the app without to pay from sites. Yes I am sure. Or you can use this app http://xdaforums.com/showthread.php?t=1652136
[LG Optimus 4X HD] iodak:
I see how it works. I sets /sys/kernel/debug/tegra_hotplug/max_cpus

That interface was in cpu-tegra3.c, that driver is no longer in use since we have cpuquiet driver now.

I added that interface in cpuquiet and it works nice will be included in next version if I wont have any issues with it.

Just to say XDA is against piracy in any way so you should not talk about it here.

Devs did they best to make that app and you should support them and buy app if you plan to use it.
[LG Optimus 4X HD] TheFerhatKing:
Yes right but I am not 18 and can't buy it.
[LG Optimus 4X HD] iodak:
Will do when i get to PC.
[LG Optimus 4X HD] iodak:
It should work from kernel side you also need to have /system/bin/sysinit script in rom. If it is not there take one from CM, copy it and set right permissions 755 owner root shell

About smartdimer it should adjust pixel rendering and saturation so it can reproduce same quality of picture with less brightness. Saves power that way.

It is also called nvidia prism display technology.
[LG Optimus 4X HD] Nemeziz 56th:
I have CPU Variant 1.

And downloaded the kernel 5 hours ago and flash.

No Bootloop or another Problem.

The Init.d work.

Tested with 99gpuoverclock script with own Values.

Checking it in sys/device/system/CPU/CPU 0/ GPU over lock.

No problems more.

LG 4X HD - Better than a Smartphone
[LG Optimus 4X HD] iodak:
Thanks.
[LG Optimus 4X HD] blumenkasten:
Here it works fine. It runs better than version 6, there was an issue with power consumption/charging on high CPU load or high temperatures. Now it works like expected.
[LG Optimus 4X HD] arnookie:
Anyone know why Trickster mod will not keep min max frequency in v7?

It worked great in v6 would set it to 1500000 max and 51000 min but now It will not stick with the lower frequency.

Edit

Sorted it just did wipes and now low feq sets fine. lol
[LG Optimus 4X HD] Manholas:
I created the folder init.d put in the file 99gpuoverclock with the right permissions. The file properties are: permissions to 99gpuoverclock rwxr-xr-x and owner to root group to root

How do I change to owner to root, group to Shell? tegra variant 1

Alright. the GPU is overclocked
[LG Optimus 4X HD] Manholas:
iodak, I would change the noop IO schedulers to sio and match with interactive, could give help. I'm with stock room and went from v6 to the latest. Is running a beauty, 5 stars.THANKS.
[LG Optimus 4X HD] Bogeyof:
I´m on stock. I tried the new version V7 from 10.07.13 (23.18). No chance to set Clocks over 1500 MHz. Used SetCpu, TricksterMod and Tegraoverclock, all of them shows setting of 1700 MHz, but it stucks on 1500 MHz. I thought this problem was solved?

I dont need it, but I wanted to report / to ask for it...
[LG Optimus 4X HD] ebreo:
I have sysinit with right permissions and owners...i will try yet
[LG Optimus 4X HD] alberteske:
It can be related with the quality of the processor mounted on your phone that is auto-detected by this Kernel to avoid unstability :good:
[LG Optimus 4X HD] iodak:
Try to reboot. What is you tegra variant?
[LG Optimus 4X HD] Winudert:
Still no new V7 version after 07-09? Battery life is bull****. Going back to V6. Stock Android 4.1.2.
[LG Optimus 4X HD] iodak:
?? Don't need to rude. I am not obligated to anything. This is my free will. Did you pay for something?

Anyway if you read few of last pages you would see that is updated. If you don't like just don't use it. That is all.
[LG Optimus 4X HD] sPEADy:
It is such a shame the way some people behave here.......instead being thankful to the person who is investing his time, effort, mind, capabilities to

build on this Platform (XDA). This is simply demorilizing for the Developers. If you do not like what they are developing here just do not use it.

If you want to use it then be prepared for this and that. No one is perfect and nothing is perfect. If each and every company make such products

which are without any faults no one is going to buy the new product the gonna produce. So keep calm and help others to get helped. If you do not

like the battery life then Buy NOKIA 3310. It has great Battery Life.
[LG Optimus 4X HD] scarfaceq:
Thank you for another update! I really like this kernel. It's blazing fast, stable, smooth and got nice OC options. Big plus for kernel is also that temp. in my case, can reach around 76 (of course while gaming and that's almost the highest point that it reaches) and It doesn't slow down the CPU which would cause lag. All 4 cores stay at 1,5GHz which is perfect. (Hvala ti puno!) :)
[LG Optimus 4X HD] QuadBro:
I found a bug in your kernel :cowboy:.In video recording,there are some framerate drop.
[LG Optimus 4X HD] Winudert:
You understood me wrong. V6 is awesome job, but V7 is not so good. I wanted one thing in V6: stock CPU and GPU clocks. In V7 everything are, but version is terrible in battery life. I thought users feedback are important to you. Plus I donated to you because of this. Yeah, free will.

Again, said many words in birds language. I'm not developer, but if V6 can perform better in battery life, why V7 can't, especially with 200MHz lower freq? My simple question in one sentence. Answer from you about XDA developers policies and rights, I believe. I'm not interested in that.
[LG Optimus 4X HD] sPEADy:
Thats the point if there is some flaw then explain it gently..........and not like that you own this thing just becuase you donated for WILLINGLY.
[LG Optimus 4X HD] @non4:
I like to report my annoyances and problems but I do anything the developer asks to help solve the issue, complaining without giving anything back is a sure way to make it NOT get fixed
[LG Optimus 4X HD] sPEADy:
I am not saying that its not good to Report back but there is a proper way to do it.

Like what I said hit " Thanks" Button.
[LG Optimus 4X HD] ectoplasma22:
I have an amazing battery life with V7 and i never had a so great one ;)

Thanks a lot for your work Iodak, this kernel is the best one i tried :D

Thank you again your kernel touches the perfection :thumbup:

EDIT : Just a picture of the Deep sleep with your kernel which is perfect for me, everytime i put the screen off, the phone goes into deep sleep :D
[LG Optimus 4X HD] DankoFGL:
In my case the phone stays hot even with the screen off, I use zaiben ROM with a couple games installed, whatsapp, tapatalk with notifications off and greenify, and also bad battery life... on v6 the battery was a lot better

[LG Optimus 4X HD] Bogeyof:
Tried Reboot a few times. I´m on variant 1...

Tried 1600 also, stuck on 1500 MHz...
[LG Optimus 4X HD] arnookie:
Same for me on v6 170000 max cpu worked fine now It sticks at 150000 max on v7

Can't figure out why :eek:(
[LG Optimus 4X HD] wajahebat:
Im migrating to this kernel...Im running stock, so which version works the best with battery life? v06 or v07 ? Need suggestion
[LG Optimus 4X HD] iodak:
You with no go over 1500, try to download again. Maybe you have old version. I will take a look at it tomorrow, some users reported that is working fine, so i don't know. Thanks for reports.
[LG Optimus 4X HD] iodak:
Something is using CPU, try to find out what. V07 should drain less or similar to v06. Anyway CPU is under clocked and only 2 cores are allowed when screen is off.
[LG Optimus 4X HD] @non4:
It drains less in my case, excellent deep sleep. BTW I didn't know about this 2 core thing, sometimes the phone gets locked to 2 cores for no reason when in use, maybe its related. Using tegra overclock or trickster can easily fix, but stock doesn't do this. Stock sucks though so fix in your own time
[LG Optimus 4X HD] iodak:
I could be tegra OC app try to uninstall it for some time to test. Never happened to me. Min and max cores online are rested on screen on-off.
[LG Optimus 4X HD] liti15:
I unnistalled tegra overclock and the batery life improved
[LG Optimus 4X HD] wajahebat:
So youre using v07 bro? Can you give me a rough comparison between v07 with stock kernel? I mean in battery life and performance...

Quite confused right now, seems there are some user reporting about battery drain in this kernel...Just wanna flash it last nite before read it through:crying:
[LG Optimus 4X HD] liti15:
Yes i am running the v07 and the batery life.is better than stock and is faster of course you can run games nearly without lag
[LG Optimus 4X HD] wajahebat:
Okay so my concerned about battery life with this kernel solved...

How about Data Connection/Wifi/Tethering & Hotspot? I use them almost everyday, so its an important thing to me...Any important bugs?

Im fine with overclock but stock cpu freq is enuff for me actually, just browsing all the time and emailing and some whatsapp
[LG Optimus 4X HD] liti15:
Data Connection/Wifi works fine hotspot i dont use but i think it's fine
[LG Optimus 4X HD] wajahebat:
Okay will flash it today, currently cant find a suitable Unlocking method for v20a...Dayumnn cant wait to test this kernel...

Do you know any method for reflashing stock kernel from custom kernel? Thanks for you bro:good:
[LG Optimus 4X HD] liti15:
I think there is a stock kernel for flashing in cwm if you dont like the custom one
[LG Optimus 4X HD] wajahebat:
Okay mine is unlocked...Now ready for flashing this kernel via CWM...

Before that, i have one question...How am i gonna revert back to stock kernel? Is it enough by just restoring from nandroid backup (created when using stock) can revert me back to stock kernel?
[LG Optimus 4X HD] iodak:
Yes, restore boot.img and system. Or flash stock kernel.
[LG Optimus 4X HD] wajahebat:
So basically if i just restore my stock nandroid backup, automatically my kernel also back to stock...

Am i right?
[LG Optimus 4X HD] iodak:
Yes, but to save some time only restore system and boot partition.
[LG Optimus 4X HD] wajahebat:
Okay get it, can do that from advanced restore menu in CWM...

Currently charging my phone to 100%, flash your kernel, and monitor how's your kernel behave with batt life from 100% - 0%

Will report back, thanks bro:good:
[LG Optimus 4X HD] Bogeyof:
Downloaded again. I´m sure, I have the latest version available (as I wrote, 10.7.13, 23.18). Doesnt work (Freq. > 1500 MHz)...

But I dont need it, so its not a big problem for me.

Why did u suppress the xmm_power_wakelock. Now I have a drain with 3% per hour and a deep sleep about 85% and cant see what´s draining, cause all other wakelocks together are about 5%. So I´m sure, xmm_power_wakelock should be about 8%-10%, but cant proove. What´s the benefit of supressing it?
[LG Optimus 4X HD] wajahebat:
Sorry dude, another question from me...

Does your kernel support fast charging like stock? i cant understand reading the first page...:(
[LG Optimus 4X HD] iodak:
Whell I marged arararagis work. Wakelock is not visible but extra logging is included to maybe find out way is that happening.

I will take a look at OC to see what is going on.
[LG Optimus 4X HD] arararagi:
I've gone over this in the baseband wakelock thread, but quick summary:

Without the patch:

- If you don't encounter the bug: Everything's fine :)

- If you hit the bug: Baseband stuck on high power :( and CPU not sleeping :(

With the patch:

- If you don't encounter the bug: Everything's fine :)

- If you hit the big: Baseband stuck on high power :( but at least CPU can deep sleep :)
[LG Optimus 4X HD] Bogeyof:
OK, sounds locigal. But I have the wakelock-"bug", normaly 8-12% with UMTS, but my Handy goes into DeepSleep (normaly 85%)...
[LG Optimus 4X HD] arararagi:
Maybe you could post your BBS and dmesg to the baseband wakelock thread

http://xdaforums.com/showthread.php?t=2229050
[LG Optimus 4X HD] Bogeyof:
OK, may be I´ll do it later on. I´m testing atm V7 and there is no entry for the wakelock in BBS. Also I´m testing with Greenify atm, so I dont want to change too much for better comparable results...
[LG Optimus 4X HD] arararagi:
We're not interested in only that wakelock entry in BBS, but everything in BBS.
[LG Optimus 4X HD] wajahebat:
Just flashed this kernel roughly three hours ago...When finished 100% charged, i directly flash this kernel and turn on my phone...

Below was my observation before and after flashing this iodak kernel...Once flashed, i left my phone with WCDMA Mode, WiFi turned on...

I left it alone for 2 hours, i came back and the battery drains 5%..I expect it to be the Wifi and the networks...

I check my cpu states, it was constantly maintained in Deep Sleep mode during the 2 hours period i left...

Ive check on BetterBatteryStats, no more " baseband_xmm_wakelocks "....Its the facebook apps that consume most power and

also, on the kernel side, its the " PowerManagerService " consumes power....

For your information, my area have no 3G network so all the time it was no reception at all..

I also turn on the EcoMode...No other setting is touched yet...
[LG Optimus 4X HD] @non4:
Well they did report they have core control bugs to fix so maybe ;)
[LG Optimus 4X HD] wajahebat:
Seems that battery is draining more faster than stock...Im using v07, how about v06 ?
[LG Optimus 4X HD] @non4:
Nope, deep sleep is amazing on this kernel, regular usage is same as stock

Sent from my smart frying pan (Tegra 3)
[LG Optimus 4X HD] wajahebat:
I dont know why, mine is different story....Just now left my phone for 2 hours, i checked again, already 5% drained...

But in Cpu Spy, all the time it enters Deep Sleep almost 2 hours, but 5% battery is lost, in stock, Deep Sleep for 8 hours just lost 5%...
[LG Optimus 4X HD] Winudert:
Same here. I had better battery life with V06.
[LG Optimus 4X HD] Dark_Az_:
This is my current best idle battery life (still using v6, mind you). Interactive + CFQ @ 1.0Ghz.
[LG Optimus 4X HD] @non4:
I had aggressive baseband wake lock on v6, wakelock was present through most of my 8hr shift. Result was about 20-25% battery. Now I can still leave work with 80%, if I don't touch at all then maybe more

Sent from my smart frying pan (Tegra 3)
[LG Optimus 4X HD] Winudert:
Maybe you can tell me, how to stick GPU clocks in V6? Because I'm trying with Rootexplorer, no luck. I have Tegra Overclock app, but I'm doing something wrong with this tool too.
[LG Optimus 4X HD] @non4:
You mean stick at boot? GPU should already be overclocked to 520, but there's a problem with the scaling which means it doesn't respond quick enough, causing lags in MC4 and maybe others. For tegra overclock you must check the master boot option and also the set at boot option within the GPU settings. For higher freqs you can try init.d scripts but I could never get them to work for some reason, sure I did everything. [MENTION=3443693]iodak[/MENTION] maybe some variants of the frequency table should be flashable or the behavior changed so new values aren't reset when we reboot.

Sent from my smart frying pan (Tegra 3)
[LG Optimus 4X HD] Winudert:
With 520 MHz in games I have very hot pan (Real Racing 3, to be exact). Normal is 416 MHz, so I want 450-460 MHz. I believe I will have slightly less hot pan.
[LG Optimus 4X HD] ebreo:
so anyone can explain how to overclock our gpu on iodak v07?
[LG Optimus 4X HD] reas0n:
damn! deep sleep in newest version on CM10.1.2 is just awesome.
[LG Optimus 4X HD] wajahebat:
I think ive found the best preset for my phone...Using trickster mod, below are my setting...Still testing, seems better

- I/O Scheduler : CFQ

- Smart Dimmer : On

- Governor : Conservative

- Multicore Powersaving : 1

- CPUquiet : Runnable

- MaxActive CPU Cores : Set to 4, but it sticks to 1

Battery consumption quite lesser than before, during on screen time able to get 3% drop in an hour or hour and a half

v07 totally have no baseband_xmm_wakelock at all...Good news, even deep sleep mode directly after screen is off
[LG Optimus 4X HD] Flying_Bear:
you're telling me you get 3% drop PER HOUR when screen is on? which would theoretically lead to 30 hours (?!) on screen time?
[LG Optimus 4X HD] wajahebat:
Thats not in heavy use, forgot to mention....While just some whatsapp and facebook, 3% drop in 45minutes - 1hour...

Sometimes its not...Not constant, it varies with my usage style, if gaming, very fast battery draining...

And just now i do video recording and playback, both for 1minutes, it does not drop even by 1% at all...Before this,

just playing a half minute video will drop 1% of battery...

I'll post some screenshots after this for all of us to make some analysis...

If i change back the scheduler to noop and after restart, battery starts draining again more fast...So i sticks with Cfq for now...

No visible performance drop since then
[LG Optimus 4X HD] Flying_Bear:
please do make some screenshots, as those are incredible stats :D on every rom, every kernel i tried, no matter the governor and what i'm running, i get around 1% drop per two mins (and this is best of the best that i could manage, it led to over 3 hours of on screen time)
[LG Optimus 4X HD] wajahebat:
Will do, my brother just played some games on my phone and the battery drops down to 16% from 26%...

What kernel do you use bro? And mind if i asking do you usually enable the fsync?
[LG Optimus 4X HD] KiD3991:
Was using Zaiben ROM, and v6, using One Power Guard and guess what, 2% drop in 8 hours, plus a 40 minute light gaming time(kairosoft 2D games). Now still at 82%. One of the best I can get.

Ondemand and CFQ.

Most wicked part is that, I am playing NOVA 3 before I charged to 100%, it doesn't even heats up.
[LG Optimus 4X HD] wajahebat:
Can explain more specific details about your settings bro? It seems interesting...

Did you use trickster mods?
[LG Optimus 4X HD] gordonbennet:
Thanks iodak and everyone here supporting it. I have a few questions:

With v7, can I clarify that both the CPU and the GPU are at their STOCK frequencies? I don't need the extra speed and would be glad to edit if anything at all is still left overclocked in v7.

Also, what does the stock kernel use as it's scheduler? Is CFQ very detrimental on the performance of watching movies and just installing apps and doing general things?

Thanks all. Loving the no battery lost during deep sleep <3

I am on Zaiben 4.1 and have upgraded the kernel it was using to v7. I ask these questions because when I browse videos and download on the phone I find that it's draining much more than stock Zaiben's kernel.
[LG Optimus 4X HD] wajahebat:
Im on v6 now...It OC'ed up to 1.7Ghz and lowest cpu freq is 102Mhz...Battery drain quite fast, 5% for 20mins...Still monitoring for Deep Sleep
[LG Optimus 4X HD] KiD3991:
Hello fellow malaysian. I'm from KL , Cheras.

Back to business.

On Zaiben, no tweaks and just V6, using trickster (I did not change much here), but on specific page, multicore powersave 2, those value below I minus 25 for all. :)

Then using One Power Guard(playstore free app), I used AI mode, then min 51 max 1000. OnDemand and CFQ. That's about all.
[LG Optimus 4X HD] wajahebat:
Damn didnt notice youre malaysian...Allrite, now on v6, max cpu freq able to reach 1.7Ghz wtff!!

So where did you apply your scheduler and governor setting? In trickster or OnePowerGuard ?

Any performance decrease when you decrease all those number by 25 ?
[LG Optimus 4X HD] KiD3991:
Nope, Nova 3 is as fluid as it gets.

Trickster is for specific settings. For One Power Guard you can see the minimum. And no, I don't think overclocking to 1.7 is going to help much. All my basic needs is fluid now.
[LG Optimus 4X HD] wajahebat:
Same to me then, now been trying to use SetCPU to lock all cores on 1.2Ghz...Trickster frequency lock just jammed my system...

I just need performance and battery life only, as been using this phone for browsing and listen to music...
[LG Optimus 4X HD] Flying_Bear:
i'm on werewolf, i have issues with baseband wakelock on iodak kernel, and ww doesn't have fsync implemented as far as i know

[LG Optimus 4X HD] Winudert:
Iodak, what is the best min freq?
[LG Optimus 4X HD] iodak:
102, it will go to 51 in early suspend. Lower is better it will not lag because of boost to 750 on input event.

Adb shell? So you connect your phone yo your PC and put the freqs whatever you want and they sticks? I'm on 150000-150000

[MENTION=3443693]iodak[/MENTION] nope I don't have any app for editing anthying of my kernel, I use it stock as it comes, I use zaiben ROM and flashed the kernel with 100% of battery, using zaiben that comes with your v6 version kernel, formates system, data, sdcard, caches, flashed ROM and booted leave it to sit for 10 mins, flashed kernel, reboot, installed apps and only that, leave one circle, I'm at the second and the battery with screen on still pretty bad, and screen off is average, in one hour drains almost 8-10%, maybe creating a script for the freqs helps...

The only "always connected" app that I use is whatsapp, I don't use Facebook, twitter, instagram or any other app that stays connected always and running in the background and for the widgets I use uccw updating every 6 hours, also I have only WiFi on, data off, NFC off, GPS off... games I have mc4, real racing 3, offroad legends, temple run, the box app is not logged in...

I unplugged my phone at 9 am, now I'm at 11.04 am, and it is at 69% with 36 mins of screen, my phone has two weeks and a half with me... so the battery is new...
