Strange, I had no problems updating to 106 but while upgrading to 109 my data partition got corrupted. I had to format it and restore my apps with rom manager. Now it's working nice and smooth, thanks for your effort!

So instability and freezes were actually caused by an error in the lowmemorykiller and not by OC? At least my phone was rock stable at 1456MHz except some rare freezes when unlocking, or maybe I'm just lucky. I miss my handwarmer.

[LG Optimus 2x] calav3ra_de:
Just try it out.. You will get of course improved read speeds with higher readaheads to some point, but as i wrote earlier, look at opening some certain programs: they will be slower, as big readahead causes the OS(?) to read much more than needed, making for example the list of installed apps slower and of course lots of other things, too.

[LG Optimus 2x] pengus77:
Experimental Release

Ok guys the time has come, i can't stand having you try to guess any longer... :D

Let's just say that the 3g modem now has a proper power management system and that tests done in the last two days report a sleep drain, with 3g on, between 1% and 3% per hour depending on the apps you have syncing in background. The LG driver doesn't implement the IDLE mode for the modem, so it's either on or off (remember wifi anyone ?). Now it's idling most of the time, also when the screen is on... as it should be :cool:

What this means in terms of battery consumption ? Let the testers explain it in a better and funnier way. Say thanks to massimo69, carloit, wfd, tetsuo55, tonyp and all those who helped check this out at 3 am with me pinging them on gtalk :D

Now, i really need a broader range of testers, so i've pushed the 110 experimental to my xdafileserver folder. The only change is the modem driver, all the rest is the same as in 109. Please keep 3g on and wifi off and report about your experience here :)

Have fun and remember, this is really experimental... don't shoot me if your 3g connection dies :D
[LG Optimus 2x] massimo69:
Re: [KERNEL][CM10/CM10.1][100p3 - 2013/02/19] Kowalski Kernel - Now With Nightlies !

Let's just say that with a good signal and 3G only on, batt consumption was limited to 2% per hour for the better part of last night :D

Considering the fact that I was getting pinged in the middle of the night and @ a party to get results and averages on consumption I would say its a pretty good result. :cool:

[LG Optimus 2x] calav3ra_de:

[LG Optimus 2x] pengus77:
Just one thing. If you're in a zone with low reception, the modem has nothing to do with battery usage... it's the bb itself that pushes the power (and the battery drain of course) to keep the signal. The modem itself only works on top of the signal management system and handles the data connections. So make sure you have decent signal when testing, or it will be all in vain :)

Re: [KERNEL][CM10/CM10.1][stable: 100p3 - exp: 110] Kowalski Kernel

I'm testing with 4.2.2 seems stable so far. Had high battery drain to start with but seems to have settled down now, see how things go after a full day tomorrow.
[LG Optimus 2x] gramaglia:
Can't wait... I feel it as a sort of coming back.
[LG Optimus 2x] brugobo:
I updated to 110 and left phone idle for three hours on its usual test location in the room. 3G only (HDPA, -105dBm, 1-2 bars reception), data enabled, k9mail and yahoo weather syncing.

Battery drain is 3% per hour while it was just 1.8-2% per hour when wifi+3G+bt were on (previous kernels).

I blame higher consumption on the fact that wifi data is more energy efficient and 3G coverage is not good in this room. I have not taken the phone out of the house today so no clue about power usage under real use cases but 3%/h is way better than I usually get on the go. There is no cell switching while stationary so I will try not to get too excited till I can test on the street.

I am switching now to wifi+3g+bt and I wil report if it lowers consumption past the 2% on older kernels.
[LG Optimus 2x] grimmyrippy:
I set the governor in ondemand and the i/o in row and the 1ghz jumping of both cores is gone
[LG Optimus 2x] antec123:
Hiya, pengus. i flashed your latest kernel 009p2 new bl, and i satisfied enough. the performance get better and better from kernel 010713. good job m8. always using interactive for cpu governor and row for I/O scheduler.

i have request, maybe it's only minor. i would like to request the CPU temperature, so we p990 owner can monitor how high the cpu temperature could be. i don't know it can implement with your kernel or not, but the last time i used was OC kernel.
[LG Optimus 2x] swifer_lf:
soon to say about deep-sleep, but when ondemand governor still 1ghz freq

i am on v2 kernel, row scheduler
[LG Optimus 2x] pengus77:
If the phone doesn't enter deep sleep it really isn't a kernel bug.... it's an app that's preventing it for you. Please give more accurate description of what you have on your phone, because you seem to be the only one suffering from this. Also, using dyninteractive in test phase, i've seen all frequencies get used more or less equally, with 216Mhz and 1Ghz getting a little more attention. That's totally normal, because the 1Ghz spikes are what make the ui feel so smooth (aside from tons of other customizations). Consider that when you open an app, it's a very heavy and resource consuming operation for the system, so it requests to the governor the maximum available speed for the few seconds needed to launch it.

p.s. Consider that if on usb the phone will never enter deep sleep. It's a design feature of android...
[LG Optimus 2x] pengus77:
Yeah i'm doing that already, i need it for thermal throttling ;)
[LG Optimus 2x] swifer_lf:
hope this will helps you -.-

but same applicationes runing will all governors, so idk why sometimes enters and sometimes not!!!
[LG Optimus 2x] x_justin:
Whats recommended around zram and swap? From logical thinking, I say disable both to make our phone faster when limit the background procs to 4, but is it safe? And is it true anyway?

Verstuurd van mijn LG-P990 met Tapatalk
[LG Optimus 2x] pengus77:
Actually it's a bit of a weird thing. See, all unix-based systems are designed to use virtual memory in an efficient way... and they like it a lot. Zram is "the google way". It grabs a small % of your ram and uses it as compressed swap space in memory, effectively reducing your free ram. Pure disk/mmc based swap is "the desktop/server way". But let's consider how it's used... it's not an extension of your ram, it's not used actively to emulate ram, it's used in a sane way to offload the rarely used, or less used - less requested - memory blocks of programs. So basically it's something good to have and in linux world is highly suggested, even if you have tons of ram. Mac OSX for example uses swap/vm files instead of partitions. It's normal for a unix based system to use it, why android should be any different ?
[LG Optimus 2x] antec123:
oh, thx. i use system tuner pro, and there is usually cpu temperature, flash your latest kernel, i don't look the cpu temp. how to see the cpu temperature?? is there any script or what?
[LG Optimus 2x] my_dnl:
It could be related to charge with phone on?

I noticed that if I boot phone without USB attached it work well (no 1GHz jump).

If I plug USB to charge the phone, when I unplug the cable I got this problem.

Rebooting phone seems solve it.

PS: I'm on old BL
[LG Optimus 2x] pengus77:
The 1Ghz bump when connecting / disconnecting the phone from usb is a thing that i introduced in the last kernel to help preventing bsods... what happened was that the charger came up with the cpu in an untrackable state. So now it wakes the cpu to a high speed for a second, then allows the charger to take over. If it's not working as it should (i tested it and seen that spikes and then comes back to 216 after a second) please tell me.

Edit: If you charge the phone, it will NEVER go in deep sleep. Only when detached it will go to real sleep.
[LG Optimus 2x] Ximo F. Verde:
Noobish question but pls bear with me.. Does kowalski-kernel-009p2-oldbl.zip already comes with one of the 2 wifi modules, or do i have to choose one and flash it on top? Thanx

[LG Optimus 2x] sokinso:
The first editions of your kernel were fast but with some bugs as we know. Insalled the last one with 150 downloaded apps in my system some lags occured due to low memory available (40-50).

So i decided to install an free ram app. Autokiller memory set to aggressive mod made my phone complete lag free(except tiny animation movements).

For example:chrome was unusable till now but now is fully functionall PLUS Lag Free. As you understand multitasking suffers a litlle with this

but for me multi. was never usuable due to big lagggggss.I think any min free ram manager app would help us.

Thank u though pengus for your great effort on this phone.

Keep going man!!!

[LG Optimus 2x] pengus77:
Uhm really 150 apps ? Cared to look at how many running in parallel ? That's quite scary for a ~370Mb free-ram phone... i can't handle that many apps on the gnex. Anyway good for you that you found your balance :)
[LG Optimus 2x] pengus77:
I use it in a very aggressive mode... 4 max background processes, disabled zram and ksm, enabled swap on the new bootloader partition, ~30 apps installed (some i don't even use ever, but they're there). DynInteractive or Interactive depending on the task at hand. Row as i/o scheduler. I constantly have ~100Mb free ram available and the system is awesome...
[LG Optimus 2x] sokinso:
With only 30 apps i get it man but 150 are not so many(most customization apps). If i Had 30 apps i would need no 3rd party app.. ;)
[LG Optimus 2x] tonyp:
Okay guys, we need better logs when you encountered a bsod.

A logcat after you pulled the battery and restarted the device is useless unfortunately.

If you do have one, please DO NOT pull the battery right away but connect it to your computer and try if you can still access it via adb.

It did work for me one time in the past.

Type adb devices and check if a device gets listed.

If it does save the logs before pulling the battery:

Save the kernel log:

adb shell
su
cat /proc/kmsg > /sdcard/kmsg.log

then hit ctrl+c to exit.

Now pull the log with adb pull /sdcard/kmsg.log

and just in case save a normal logcat as well with adb logcat > logcat.log

Now pull the battery and attach or upload both log files (e.g. to pastebin.com)

Hi brugobo,

I might be reading it wrong, but what you're saying doesn't make much sense to me... You either have 3G data or you have wi-fi, you can't have both.

So I think you're actually comparing 3G data to wi-fi and BT, and to me it makes sense that wi-fi drains less than 3G data, specially if you reduced TX power in kowalski manager.
