This kernel doesn't support more then 3 points, and it's not because of the screen undervolting.

Pls correct me if I'm wrong
[LG Optimus 2x] Ajsh:
Sorry I don't know the answer to your question, but this got me thinking. Sometimes the backlight of my screen partially turns off. Could this be due to the UV?

hi, can i put this kernel on v20s?
[LG Optimus 2x] 60nine:
afaik, it's not baseband related...

i'm on v20L
[LG Optimus 2x] DeepRed89:
i know...but i flashed it on just flashed v20s with only cwm 6.0 and after flash the device go in bootloop...why? how i have to put it on?
[LG Optimus 2x] 60nine:
did you flash the right coresponding bootloader version?

there are 2 versions - old and new bootloader

which rom are you on?
[LG Optimus 2x] DeepRed89:
i just flashed the v20s so i'm on the old boot and i downloaded the oldboot version of M1
[LG Optimus 2x] sgspluss:
You cant flash kowalski kernel on GB roms ;)

To fix your problem with bootloop flash an GB kernel, then your phone should work again.

If you want to use kowalski kernel update your rom to min. ICS then you can use it.
[LG Optimus 2x] DeepRed89:
so is not supported for v20s?
[LG Optimus 2x] sgspluss:
No just ICS and JB, GB will doesnt work as you can see...

If you want to use kowalski kernel you have to flash ICS or JB.
[LG Optimus 2x] DeepRed89:
okok...so...what kernel can i use? horsepower?

Maybe the answer is somewhere in the 740 pages of this thread, i did not read all of them:silly:

norh means NO RAMHACK(norh) other one is with ramhack, with ramhack more RAM its available

so try both and see...
[LG Optimus 2x] :
So if I want to test this with a existing rom on my phone, how do I flash it? I mean, do I have to wipe all data and reflash the rom, or is it enough to wipe cache and dalvik cache and then flash the kernell?

We've identified that the problem is due to SatStat querying the Ambient light sensor. Would this be because of a bug in the kernel?
[LG Optimus 2x] louiscypherbr:
I have this kind of bug also on GPS status, but it's solved turning screen off and on. Even if it's a bug on kernel, I don't think it's something to work on, since 3.1 is much more important and I can live with this workaround.

Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

Rom/apps problem. Kernel has 0 to do with userspace.
[LG Optimus 2x] FatherJony:
I keep reading this and although it's not exactly kernel related i feel i have to explain one thing: Zram or/and swap will never ever boost performance.

Zram is a way to fit more data into your ram by using compression and said compression adds overhead. The system creates a compressed swap block inside your Ram and uses it to store processes not currently in use when your device runs out of ram. Doing this will free up some RAM by adding more delays due to compression on top of those caused by the probable memory block rearrangements that happen when memory is close to full. The zRam value you set is the percentage of the RAM zRam will use for the swap file, a value of 10 is faster than a value of 18 because you only get a swap file of 37mb instead of 67. Keep in mind that since the swap file resides in RAM, it actually reduces the size of RAM your system can use before having to resort to swap, and swapping degrades performance. So if you primarily care about performance, the best value for zRam is, that's right, you guessed it, it's ZERO.

Swap on the phone memory is even slower even thought there is no compression, as the phone internal memory I/O speed is several times slower than accessing the RAM, so you get the picture.

If you want to keep your phone performing well, kill the apps you don't currently use, ESPECIALLY the browser. Just long press the menu key and swipe everything away. Apps that always run in the background like fb, skype, viber etc are also a bad idea with this phone and everything newer than Android 2.3. If you can't deal with those restrictions you either have to roll back to gb or get a new phone with more ram, a kernel won't ever be able to increase the physical ram of your phone.

Lol, where is TonyP and his RAM increasing application when you need them :p.

Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

It's a known cm10 bug. Look in the users forum... It's the userspace battery management that screws up badly. There are a couple patches on gerrit and i think temasek implemented them in his rom already ;)

Same kernel + ics = no such problems = cm bugs

Is there a command line to set CAM mode with screen off too? Annoying router from my parents house...

Hello Pengus

I absolutely understand how useless this comment is but, due to huge load of work i can't do any testing/logging for the time being. I just wanted to mention that I also find last kernel to be more battery hungry than the last one, both in idle and use time. As soon as i get some free time, ill provide w all details i can get from BetterBatteryStats or other logs. Fact is that im running on a relatively stable setup (havent been installing/unsinstalling any apps lately, with the exception of a scrollable news widget which is not auto updating) so i notice pretty easily if there's any higher (or lower) drain. Im on CM10 20130103 nightly (old BL), latest Kowalski and your preferred settings (governor, scheduler etc). Again, sry if this has been a waste of time.

I just read through the op once again and also the std module will not let Wifi in cam when screen is off, will it? Though the original Wifi module did this.

So I'd propose to add such a sysfs interface as well, my work Wifi cannot even handle fast psp unfortunately. Or would 3g be less battery consuming them and I'd better throw out my office out of my Wifi list?

Regards, Orgler
[LG Optimus 2x] pengus77:
Well hi there... the std module goes indeed in PSP Fast mode when asleep, pretty much as on every aosp device out there (nexus series). So i find it really strange that your work router doesn't handle it, being a standard. Anyway, is it from the 90s ? :D

CAM mode when alseep is 1:1 compared to default CM10/CM10.1 behaviour. So basically your phone will last barely 6 hours with wifi on. If you really think this is doable i can compile a module and upload it, but is it worth it ?
[LG Optimus 2x] lucfig:
Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

I wanted CAM when asleep because I get some disconnections from the router when the phone is in deep sleep. I know that because my "home" profile gets deactivated in Tasker.

But knowing that it will suck battery life that much, I won't use it anymore.

So, for me there is no need to compile the module.

Enviado de meu LG-P990 usando o Tapatalk 2
[LG Optimus 2x] pengus77:
Eh, it's messy but CAM mode is intended primarly for laptops/desktops when connected to charger. Intel sets PSP Fast when on battery, Cisco suggests the same (on laptops, not even on phones), so i think it's just right to follow the guidelines of those giants. CAM is the max power wifi mode, it will suck more or less 5/7 times more than Fast PSP in the mid run. Fast PSP goes into CAM mode when in use and falls back to PS when idle, so it's the right balance i think.

If your router doesn't support any kind of power saving mode (which, again, is strange) try checking if there's a firmware update for it.

Anyway, i'll put a 100% stock (CAM always on) module up as soon as i figure out how to make a cross-module that Just Works™ ;)
[LG Optimus 2x] orgler:
AW: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

You maybe right. I'll give my router a last chance tomorrow, if I understood everything correctly the wake_pm is irrelevant if I get disconnects while the phone is in sleep. And it will be sufficient if I set max_pm=0, right?

It's a Vodafone easy box 802 with latest firmware. My boss is also having problems using a nexus 4, my HTC Desire however never had such problems.

Hi [MENTION=3783116]pengus77[/MENTION], all:

First of all, many thanks all for your effort in this project.

I would like to contribute with some wireless related improvements.

I have tried to compile Kowalsky Kernel from GitHub sources (https://github.com/pengus77/lge-kernel-star), and I'm facing some problems in the deployment phase.

I can generate both zImage and Modules without any errors, but once I deploy it to the phone it just freezes / stucks at LG logo.

--------------------------------------------

My environment is he following:

--------------------------------------------

Ubuntu 12.04 64bits

1: Download the source code from GitHub https://github.com/pengus77/lge-kernel-star;

2: Download the Linaro Android Toolchain from http://releases.linaro.org/12.07/components/android/toolchain/4.6;

3: Export variables to make a cross-compilation:

export PATH=$HOME/android/android-toolchain-eabi/bin:$PATH

export ARCH=arm

export CROSS_COMPILE=arm-linux-androideabi-

export KERNEL_DIR=`pwd`

4: Create .config with my phone configurations (I have also tried with make cyanongenmod_p990_defconfig - the same behaviour!):

adb pull /proc/config.gz

gzip -dc config.gz > .config

5: Build the Kernel:

make -j1

Note: Since I'm using OldBootloader, configuration includes: CONFIG_CM_BOOTLOADER_COMPAT=y

--------------------------------------------

***

--------------------------------------------

Mobile Phone settings:

--------------------------------------------

ROM: CM 10.1-20131006-Nigtly-p990

Bootloader: Old BootLoader // CWM Recovery

--------------------------------------------

***

--------------------------------------------

Deployment Details:

--------------------------------------------

1. unziped the kowalski-kernel-100p5-oldbl.zip from http://goo.gl/fzv1v,

2. and replaced the zImage and the modules

3. Then, I zip it again, and push it to sdcard

4. Flash the zip using CWM Recovery

--------------------------------------------

For now I don't changed anything in the source code, the goal now is just to compile it from source. Then, I can start my implementation / contribution on wireless module.

Any hint or suggestion to enable the correct boot with the kernel compiled from source?

Thanks for your help,

Hello all,

I have tried with Google's toolchain, but the result was the same.

After configure the cross-compile variables, namely put the toolchain in path and set ARCH=arm & CROSS_COMPILE=arm-linux-androideabi-, I basically clone [MENTION=3783116]pengus77[/MENTION] github. I have just cloned the jb-412 branch (it should the one used in 100p5 kernel version).

As I reported before, I'm using the OLD bootloader. Nevertheless, I'm using the ".config" file downloaded from the LG P990 running CM 10.1 + kowalski-kernel-100p5-oldbl.zip (download here).

I have created a new update zip, with my zImage + modules.

You can download it here: kowalski-kernel-100p5-compiled-vb33-oldbl-v00.zip [VERY IMPORTANT: THIS KERNEL IS NOT WORKING (NOT BOOT) !!!]

I have also upload the used configuration file, download at config_p990_runnning_kowalski-kernel-100p5-in-cm10-1-OLDBL

The compiled files size is similar to the one released by pengus77, however both zImage and modules are a bit bigger.

Looking forward to hear from you,
