So.. someone test attached kernel without grouper framework and report back please if cpu can go lower than 340mhz thanks
[LG Optimus 4X HD] chasepoes:
I'm on the road right now, so I have no access to adb. If you can post a CWM zip file I'll start testing immediatly
[LG Optimus 4X HD] milossimon:
Use app called flashify no need for pc

For me all for cores online at 340 cant go lower...im on revolt rom
[LG Optimus 4X HD] Kanad:
Dear Dev,

Are you sure that the bug of 340 MHz is related to C9 patch and not to the interactive governor patched from mako version? Can you make a test version with the c9\grouper patch but with a older interactive governor?

Regards,

Kanad
[LG Optimus 4X HD] Demetris:
1.Is related to none of the above

2.Yes but there is no need for it.
[LG Optimus 4X HD] chasepoes:
Thanks for the tip. But being out on the road and not familiar with that piece of software and only having my P880 with me, I won't use that for now.

If I f*^%k something up, I've got no way of recovering my phone.

So hopefully Demetris is willing to provide a CWM zip file.

[LG Optimus 4X HD] LMartins.338:
Analyzing the gpu of our device could notice that is low compared to others of the same chipset, for example in the AnTuTu optimus 4x hd gets the gpu score in 2500, while the htc one X in 4000 and the games are much more fluid it may because of that the rest of the unit is similar scores, so I think it is the major deficiency in this beautiful handset is this though is up to you! Thanks by great job
[LG Optimus 4X HD] Demetris:
Am using stock gpu frequency 416mhz and my score is 2580 so is hard to believe that a stock freq on one x is 4000.

Also consider that i make sure we are using the latest Nvidia Tegra3 driver ;)
[LG Optimus 4X HD] KiD3991:
I was browsing on devices using the T3 chipset, their GPU clocks are at maximum 750. I forgot which thread but its the one in HTC one X, and their minimum CPU clock is 25?!

So I was thinking what is different. But if its you I have confidence in this device.

Good luck!
[LG Optimus 4X HD] Mikolaj612:
Hi Dev is there any option to make a kernel for stock JB ? I personally don't prefer/use a CM or CM based ROM's, so stock based kernel will be a nice alternative for some users like me, almost everyone forget it.
[LG Optimus 4X HD] tool_king:
Just try Iodak's kernel, he offers a stock version as well.

Reverted back to V2.11. V2.5 is eating up battery when idle, probably due to the 340MHz minimum CPU lock.

[LG Optimus 4X HD] Maczuga:
As far as I can see from github the changes would be:

- revert all 2.5 changes.

- Limit Max Speed to 1.3Ghz During Transitions for better battery life

- cpu undervoltage (725->600)

- gpu set to 482MHz

- minor tweaks.
[LG Optimus 4X HD] chasepoes:
Thats what I figured out, and the zen i/o schedular has been added. Would like to see all cpu/gpu speeds at there stock maximum.

[MENTION=860173]demetris[/MENTION]_l

Some Question they will be asked.

1. Why you delete the 2.5 Kernel Version?

2. What do you was meaning that we are in Nexus 7 Group?

3. Can you add Hot Plug control how 2.5 but maybe with more settings?

The 2.3 Kernel Version have the same Charing time how Iodak kernel. (very good)

In the 1.9 Version on your I was haved a deathly amazing deep sleep. (6 Hours Deep Sleep= -1%)

I drive today with a tour bus form Spain back to Germany and was hear music.

I notice with CPU Spy, screen was of by listing that on Iodak v7 kernel it something scale to 640mhz,1040mhz,...

On your its always 340mhz (again very good work).

When I was listed music I used your 2.5 kernel in CPU Hot plug I set min MHz when display of on 104mhz.

Can you fix it that the music play smooth on 204mhz or lower?

[LG Optimus 4X HD] Maczuga:
I can confirm this too. Happend to me twice.
[LG Optimus 4X HD] Demetris:
I think is related to Tegra variant edition hmm

Really nvidia make our dev life difficult :)

Ok here it is how it goes from here.

I will reverse back to stock without any major battery life savings for now.

(Doesnt mean i wont tweak it for performance :D )

After kernel is feature full we can go back to tweaking cpu/gpu for battery life if any needed ;)

If anyone has a different opinion express it now as you guys are my best beta testers ever! :D

And thank you for that! ;)
[LG Optimus 4X HD] @non4:
Do not sacrifice performance. GPU freq is particularly important, and all except eternity kernel don't scale up fast enough, requiring tools like tegra overclock. GPU doesn't seem to affect the battery much anyway, find savings elsewhere ;)

[MENTION=1149134]demetris_I[/MENTION]

For me your kernel is best preformanse kernel...with exelent deep sleep....i know battery drain fast when playng heavy cpu games but for me also drain fast when just using simple apps and playng simple games and browsing internet.....I notice that in those simple operations all 4 cores are turning online...it would be great if you can limit it to one or two..... :fingers-crossed:

Thank you for your work :D
[LG Optimus 4X HD] masmoe:
I think better you do like previously. I mean you bring new features and update driver (if any) to your kernel but like its motto "clean, stable and smooth". So far till V.2.10 you already have excellent work.

I agree with your opinion, make kernel full features and stable after that you can tweak it if needed.
[LG Optimus 4X HD] chasepoes:
Good idea. But try to stick to your original motto of keeping the kernel clean, stable and smooth. Don't overload it with every single option, just to keep every single user happy.

You're doing an excellent job so far, keep up the good work! Your kernel and ROM ports are the only reason I'm sticking with this phone.

P.S. A hot cup of coffee has been sent your way, to say thank you for your work. Enjoy it!
[LG Optimus 4X HD] Zhus06:
just a question.. what about you taking the 3.4.x kernel and deving on that? take the eternity one and try something? :eek:

maybe you will have it easier(which i seriously doubt) but maybe it would be even better ?

just a question

...
[LG Optimus 4X HD] Nemeziz 56th:
[MENTION=1149134]demetris_I[/MENTION]

Maybe you can build one or more features:

S2W (Sweep to Wake)

Color increase (Live Color)

New Tegra 3 Driver &Video Driver (Better Tegra 4)

The Rest i forgot when you will build in in your next release I was very nice :)

[LG Optimus 4X HD] Demetris:
S2W (Sweep to Wake) battery life?

Color increase (Live Color) how much more color you need from an HD panel :rolleyes:

This is really interesting :D

Any source code?
[LG Optimus 4X HD] Nemeziz 56th:
S2W isn't important.

Color Increase. Look at kholks kernel the color is much better than as stock color profile.

Tegra 3 Driver & Video Driver.

Better were Tegra 4.

I saw that kernel maybe you can make what something from this:

http://xdaforums.com/showthread.php?t=2307051

Excuse me when I make maybe a mistake :)

LG 4X HD - Better than a Smartphone
[LG Optimus 4X HD] Demetris:
I think tegra 4 drivers not possible on 3.1 kernel

Ask kholks that has a 3.4 kernel if he can do it.

As for your last line i have to say to you that you are excused :angel:
[LG Optimus 4X HD] raviboy100:

But there is no s2w
[LG Optimus 4X HD] varadinum:

[LG Optimus 4X HD] someth1ng:
The colour on 4X at stock is perfect. It is very natural and balanced, why would you want anything else?
[LG Optimus 4X HD] Nemeziz 56th:
Yes a little bit stronger color how by kholks kernel, but this kernel are better in performance than kholks.

I don't won't buy a Samsung bla.. bla.. bla

Because this phone have a super design and a really hot screen the list is to long to say all features of this phone.

I love this kernel and I would help that the kernel be better here's is my errors (or something what wrong is )

Battery charing take a very long time.

In the game Blitz Brigade its lag it test later again and report.

I think the Kernel is very good :) Very smooth and the Row sheduler is the perfect choose for smooth working phone :) But today, wenn i played a game (Dead Trigger) and listend to music (by the way perfect fps in dead trigger), after a wile it started to lag as hell the music couldnt be played smooth and the game had like 0,5 frames. So I killed my handy by putting out the battery and restartet. First it was smooth then the ultra lag came again :D So maybe its a Temperature throttle problem? Because today it was a very hot day :)

[LG Optimus 4X HD] tobixdev:
before he should try that he should wait for it to become stable (kholk has experience in porting 3.4 kernels I don't know if demetris has this sort of experience) and then just if he wants to do and kholk gives him the permissions to do it
[LG Optimus 4X HD] Zhus06:
you missunderstand the word open source, he ported more ROMs then anyone, he could make it stable? 2 brains are better then one and in my experience the 4.1 kernel should be replaced
[LG Optimus 4X HD] tobixdev:
yeah ok its open source but asking doesn't hurt.

He is a good dev but you can't compare porting roms and writing kernels. And even there is a difference in writen 3.1 and 3.4 kernels.

I know that demetris is a great dev and I appreciate his work but I don't know if he worked on porting a 3.4 kernel to a device yet.

i hope nobody felt affended by my post that wasn't the purpose of it.

[LG Optimus 4X HD] Demetris:
2.5 Kernel Version was deleted because after grouper framework implementation i should have deleted cpuquiet and nvidia hotplug frameworks. With both on ->mess, cpu was choking and you could see that in benchmarks.

I can add grouper framework back anytime :) so for now we continue as we are, that is with out it.
[LG Optimus 4X HD] chasepoes:
That is easy to remedy. Power off your device (when not possible remove battery) and power on holding volume up and power button at the same time (the 'hardware-way' of entering recovery). When recovery is up, reboot the device with the reboot option in CWM. Now it should boot normally.

This happened to me to. Somehow going into recovery with the 'reboot to recovery' option from within the ROM keeps the phone rebooting into recovery every time it is powered on. It seems like the software 'flag' to boot into recovery does not get cleared when going into recovery via a software reboot. Using the described method solved the problem for me. No every time I have to go into recovery mode, I power down my phone and use the 'hardware-way' of entering recovery, thus avoiding the problem.
[LG Optimus 4X HD] Nemeziz 56th:
When you release later a new kernel version can you please add back Hotplug with few more settings?

I think the people which use your kernel would like it because they have the full rights about their CPU.

LG 4X HD - Better than a Smartphone
[LG Optimus 4X HD] DankoFGL:
Sorry, let me see if i got it...

i reboot to recovery powering off my cell, after that, boot to recovery, flash the kernel, wipe all that is need to wipe and after the kernel installed, i pull over the battery and power up the phone normaly?

i will try and come back... also i will flash the v 1.7 version because i have read that is the best battery of all...

EDIT: worked, also i flashed the last v2.11... first time i feel my LG so heat using Cyano... i feel that i was back on Stock V20C... hahahaha but now is increadibly FAST FAST FAST... i will leave it sit and stabilize, maybe with a couple of days it will feel better and cooler like always...
[LG Optimus 4X HD] chasepoes:
Well almost, but your version works to :laugh:

My version: Power Off the phone the regular way (no recovery, just shut-down). Start phone and boot into recovery with power/volume-up keys. Flash kernel/ROM/Whatever. Reboot phone using CWM 'REBOOT SYSTEM' option.

The problem occurs when you have a running phone (as in functioning normally) and you use the 'REBOOT RECOVERY' mode from within the advanced shutdown menu. If you do that, then you get stuck in a recovery bootloop sort of thing.
