[LG Optimus 2x] Harsh:
I do not know what would be your problem, did you check your installed applications, which are running actively in background, that may slow our phones down, as our O2X comes with very limited RAM

Nothing that I know, but sometimes reboots into recovery from ROM power menu dont work. Normal way "Vol Down + Power" of going into recovery always works.
[LG Optimus 2x] smashman42:
Speaking of limited RAM, I can't seem to get Zram to work regardless of which CM9 variant or kernel I use (currently Owain's latest with the latest kernel in this thread)

Does one enable it in CM settings-->performance-->memory management or does it involve editing init.d scripts?

I figure with a dual core CPU & stunted RAM the trade off should be worth it

Uploaded new build 0208 with stock for normal users and also OC version for over-clockers :D

Changelog:

build 0208 Stock & OC

Linux Version 3.0.39

Reverted various fixes which were implemented in 1907

Compiled with linaro toolchain on OS X

Links in OP, and also in my signature
[LG Optimus 2x] imayoda81:
after some days in SE 2011 xperia smartphone I can say 512MB ram is not a problem in ICS... sonys are very very responsive even after 2-3 days uptime. There are things still to fix to achieve ICS smoothness... LG related obviously :(

Just my two cents

[LG Optimus 2x] Harsh:
Hi, I see that you are having troubles with KANG, seem like your phone is misbehaving. Can you try nullifier and make it all clean. And than flash kangs as normal. See if it solves your problem.

New kernel uploaded, now with defualt SIO scheduler. Kernel version 3.0.26.
[LG Optimus 2x] Basil 123:
I was on BB725 v20Q and it gave problems with call signal/quality. Smartflashed 313 and all seems well again.
[LG Optimus 2x] Harsh:
Baseband is related to phone, for me too any baseband which is not from SU660 makes bad quality, and BB725 is for p990. It dont go well with CM Roms.

For stock 725 is ok, but for CM i would go with 824/1120 BB, which are from SU660, works best on P990 made in korea.
[LG Optimus 2x] dasklney:
Just flashed 2503 kernel, everything is working great at the moment :D
[LG Optimus 2x] lipisak:
Just flashed last 2503 zip and everything seems to be ok. But antutu still shows me bad results in SDcard IO. Shouldn't this be imporved in this build?
[LG Optimus 2x] diddiman:
Can't send SMS with the new Kernel... Worked yesterday with an older though...

Of course now it's working!
[LG Optimus 2x] Impact7:
I´m losing network after a few hours. Has anybody the same issue?
[LG Optimus 2x] diddiman:
So you are suggesting that I (using CM9 on my P990) should use BB 824 or 1120 or am I misunderstanding you?
[LG Optimus 2x] rudous:
Impact7...If you mean wifi it happens to me too. After long inactivity wifi turns off and doesn't reconnect by itself. I have to switch it off and on again.
[LG Optimus 2x] Harsh:
Yes, if your phone is made in Korea. Check your box and if yes flash 1120 bb

If I use BB 1120 I need to use ro.telephony.nitz=GMT for automatic clock?

Edit: no It doesn't work .
[LG Optimus 2x] eniux:
1120 & 824 I tried both, but I can't use the rils cause I can't make calls then and I get fast battery drainage :(

Verstuurd van mijn LG-P990 met Tapatalk
[LG Optimus 2x] Striatum_bdr:
On cm roms you can use GB basebands but you should keep a froyo ril, like the one by default 0218.
[LG Optimus 2x] wkpark:
Antutu result of sd speed is somewhat slower than SD tool result.
[LG Optimus 2x] eniux:
I know :) Just not a big fan of 218, really bad sound.

Verstuurd van mijn LG-P990 met Tapatalk
[LG Optimus 2x] Basil 123:
so what is the most updated Froyo ril that works?
[LG Optimus 2x] Impact7:
No, it´s after a couple of hours. I´m using CM9 for many weeks but never got this problem. And airplane on/off doesn´t work all the time.

I´m not sure if it´s kernel specific, but it seems to be.

Right now, I use HP kernel, so let´s see.
[LG Optimus 2x] Striatum_bdr:
I guess it's 0725 v10d ? The most often used i think.
[LG Optimus 2x] pastime1971:
it should work, if it contains NITZ fix included in the source.

@ harsh, do you build the CM9 kang as well ?

just in case it is not included, 000_lge_nitz.diff will modify LGEStarRIL.java > responseNitz so that NITZ override can work.

p.s. it is totally up to harsh's decision, but i think it may be better to keep this thread for kernel only ?
[LG Optimus 2x] Harsh:
Un-reboot?

Is it hot reboot(fast) or complete reboot?
[LG Optimus 2x] TacoLoco:
Does the tonyp rom still works butter smooth after applying this kernel? Don't want to try as I don't have original kernel to revert to.. Thanks in advance..
[LG Optimus 2x] orbital_71:
Mine case is when i press reboot, it would screen off and phone need a battery pull to on back. Couple of time for today try.

Massive battery drain with bouth version.

30 min -5%!
[LG Optimus 2x] tonyp:
To revert you simply reflash the rom.
[LG Optimus 2x] Nova163:
I'm trying out this combination right now, and it appears that it runs less smooth than with the default kernel, but battery life seems to improve.

I've only tried for a day though so I can't tell for sure.
[LG Optimus 2x] aragorn7:
Both versions work great on my su660. Nothing to report as bug - just great! Thanks for your hard work Harsh.
[LG Optimus 2x] Harsh:
Glad that its working on SU660. And thank you very much for your appreciation. Sorry I just saw it late, was not logged in email since 24 hours, had exam today. Went good, so now free again :D.
[LG Optimus 2x] orbital_71:
so far the kernel i find most stable are 3.0.34OC and 3.0.38 no problem at all and charging also very fast.
[LG Optimus 2x] flat__line:
Thanks for the new kernel 0208. I am using it on NOVA HD: good battery, smooth, good benchmark results

BUT

I got one spontaneous shutdown (may be un-reboot) : however it powered on manually without taking the battery off

ooops: another one :(

one more :( :( (battery extraction required)
[LG Optimus 2x] flat__line:
Noob question ...

what is causing charging BSODs?
[LG Optimus 2x] orrebo:
I use this kernel with another rom and doesn't have this issues. Or it have only ones or twice. So I think it can be a rom issue maybe?

Sent from my O2X running MIUI 4 with Harsh kernel
[LG Optimus 2x] ykin:
This is a great kernel working perfectly with ParanoidAndroid. :good:

Thanks!
[LG Optimus 2x] snel76:
As far as i know charging BSODs are a CM related problem(anyone correct me if i am wrong). In settings/development (dont know the exact english name, sry) there is an option to keep screen on during charging, this helps preventing charging BSODs.

@ Harsh: By the way, Kernel is awesome, no BSODs for me in combination with Paranoidandroid, everything is super smooth and stable.
[LG Optimus 2x] Stefan Gündhör:
Also with Owains's ICS ROM. I like it very much; smooth, snappy and power consumption is okay too! :good:
[LG Optimus 2x] Remuzzz:
Downloaded the latest de kernel and most of the time it works great on Mr Hydes ROM. But when I enable wifi and the phone starts to sync things, like mails and program updates, the phone becomes extremely laggy. And some processes don't react anymore.

Anyone else have this problem? And is there something I can do about it?

Thanks!
[LG Optimus 2x] PYCON:
This version of the kernel causes to my phone a strange little bug...

Second core is often offline. But not always... I don't understand why...

:confused:
[LG Optimus 2x] SuperSkill:
Depending on kernel it also happens using stock based ROMs...this is the issue in addition to SODs that needs to be solved when integrating the existing and new features to OTF kernels ;)

Ps! Not all phones have this issue and some have it more often than others. I've had 2 o2x devices, the old one struggled, the new one don't, both charging or not (boring without any issues I've learned lol) :)

[LG Optimus 2x] fuxmen:
Read last couple posts in paranoid thread :)
[LG Optimus 2x] tonyp:
It's the same guy who asked over there :D
[LG Optimus 2x] p.valenta:
Yeah, I have same issues from first versions of CM9. I looks to me like problem with storage access. Same annoying thing is system process crash during installing/updating/uninstalling Apps. I don't think it's related to kernel, but to CM9.

I hope these issues will get fixed after released official LG ICS.
[LG Optimus 2x] flat__line:
On Quadrant ...

just curious,

I am testing several kernels with Dark Ice Edition, searching the most stable for my phone and having a look at benchmarks (I know, they are not well correlated to smoothness and usability ...): I (a noob) was surprised by the difference I get from Harsh's with respect to others (such as Nova) on Quadrant, while getting more or less the same results on AnTuTu.

Harsh's gives a definitely higher score (say 3200 vs 2400): what kernel optimizations are in place to justify the difference?

Thanks,
[LG Optimus 2x] Harsh:
All must be same except IO score in quadrant, which should be higher in my kernel. You can sometime unzip the kernel zip and check init 99vroom script. Those are morfic's optimizations for IO, and works pretty well.
[LG Optimus 2x] flat__line:
cpu governors...

what is the strategy currently controlling the activation of the second core? is there any app (such as those available for guestekrnl) to tweak the parameters?

thanks a lot,
[LG Optimus 2x] aldyu:
Which version is usb tethering working? Tried the latest and the 3.0.37 but not working for me...
[LG Optimus 2x] Harsh:
Cpu controlled by nvidia itself. No governors work on tegra 2.

I don't have gueste kernel tweaks and not so I have app for kernel control. Sorry.

Well work on Windows only. Working for me on latest kernel.
[LG Optimus 2x] aldyu:
Im on win 7 x64, ok using cm7 though... i notice driver error on mtp device when usb tethering is enabled..
[LG Optimus 2x] flat__line:
CPU control ...

Is it possible to specify in some system config file parameters such as:

min/max CPU frequency

activation/deactivation threshold (freq and time) for second core?

Thanks a lot,

[LG Optimus 2x] emanuele95:
Harsh, does your kernel support multicore in cm10?

Tks
[LG Optimus 2x] Harsh:
It supports zram and you can also enable it with his memory tweak, but I do not understand what Benee mean to say about zram for multicore. As i assume ZRAM act as RAM, which should not concern number of cores. But I do not know exactly what Benee meant so cant give you answer on that. Sorry, my knowledge is restricted here.

EDIT: Okay got it, Script in Benee's memfix zip makes 2 zram partition, 1 for each processor core. I guess this should work in my kernel too.

EDIT2: In my kernel it is making just 1 swap partition. Will update later today to support 2.
[LG Optimus 2x] rachit_rox:
harsh, is the USB OTG still in works or has it been scrapped??
[LG Optimus 2x] Harsh:
Scrapped until new sources come out. Hope lg dont mess with kernel this time.

Sorry, deleted...
[LG Optimus 2x] bihariel:
Hey man, great work.

I am using your kernel to test in my miui 4.1 jellybean port and i am having some touch screen lag and unresponsivness.

what do you think is the problem?
[LG Optimus 2x] thorstenhirsch:
Hi Bihariel, are you using a public git repository so that others (me) can take a look?
[LG Optimus 2x] bihariel:
No i am not using git, i am not using source code because it is not available by now, i am smali editing. The ROM is almost ready, only i have a little problem with data switch shortcut on status bar, with harsh kernel it works but with bene kernel it FC. The problem is that harsh kernel is giving me touch screen lag. hope is fixed in his next version.
[LG Optimus 2x] Harsh:
I too think benee got faster kernel. Using memfix zip on default kernel make 2 swap partition in Benee's kernel, maybe extra zram making it faster.

But I do not have screen lags in any kernel.
[LG Optimus 2x] bihariel:
I don´t mean lag=slow, what i mean is that the touch screen stys unresponsive some seconds then it works well.
[LG Optimus 2x] aragorn7:
Thanks harsh. It's running great on tonyp's ParanoidAndroid #11. :)

Just a quick question...any interest in adding a bfq scheduler? Noticed that's what benee used in his hackfest kernel, albeit, I don't know if it will make that big of difference in the overall performance.

I guess maybe a better related question is, how do you decide which schedulers to include and which not to?
[LG Optimus 2x] Harsh:
Default cyanogen kernel use bfq. I adopted to sio after lots of tests. N feels its better.
[LG Optimus 2x] Harsh:
New build uploaded 0509.

build 0509 Stock

Compile zram as module (Thanks Benee)

Fix zram for dual core

This build contains memfix init.d scripts from flak0 and dual core zram enabler. (All credits to flak0 and Benee)

Removed my 95vrooom script for better option from flak0, Quadrant score may fall, but it will surely feel faster.
[LG Optimus 2x] skylinegt77:
thanks a lot harsh, will test and report when i feel i should. hope that the no waking thing doesnt happen with this build ^^

How about OC opportunity? Would be great to have, as I do some "hard" stuff with my device^^

EDIT: OC version live on goo.im and mediafire folder
[LG Optimus 2x] skylinegt77:
i do not have any lags and the kernel works very good 4 me, but as for the slow opening of apps, i really think that issue is due to the very small number of memory allocations. hope harsh looks into it ;)

Hi thanks aragorn. I have also started kernel development, and doing it for ICS stock to work with old bootloader. Now its almost perfect.

So will release flashable ICS stock, with everything working. Perfect camera pictures (not dark anymore), Bluetooth working. Screen on/off working. Bosd on deepsleep fixed. And to add it on all, its flashable zip which can be flashed with CWM 5.x.x.x easily.

so a cmw flashable ics stock with all working??? wow! almost identic with the official upgrade ics of LG will be released in november

Thanks you harsh
[LG Optimus 2x] Harsh:
Not sure if I should mix v28a with v30c or not.

One problem remaining to solve i.e. camera app FC after 1st use, will look into it tomorrow. Can be used again if clear data on camera after first use. But there should be permanent solution.

This is the best news I heard recently! :) Sounds soooo promising... So far, CM10 doesn't seem to work for me (not saying it's bad, but too many issues in my case), so having a working ICS would be a blessing! Not too much faith left in LG, so definitely looking forward to it!

Hey any update on if OTG is working?
[LG Optimus 2x] tonyp:
It's not just not recommended - it's currently not working with 6.x.x.x.

Which flavor do you suggest/use?
[LG Optimus 2x] tonyp:
I'm using official 5.0.2.0. When you use a new 6.x recovery you will get an encryption error after booting up the newly flashed ROM.

I'm not yet sure what's causing this, but harsh wanted to Google around a little bit today.
