If anyones interested, i wrote a couple of scripts to manage some cpu stuff on my tegra3 tablet running linux, but ive adapted them to work on p880 android. We all know scripts are better than apps :)

https://www.dropbox.com/s/a46ayucfhbrsaka/cpuquietandroid.sh (this simply changes cpuquiet gov, trickster does a fine job of this though.)

https://www.dropbox.com/s/54qxo5fhybx3v83/cpucores.sh (this sets the number if cores online, [MENTION=4681015]Ben36[/MENTION] this is what you want i believe. Set the cpuquiet gov to "userspace" then in my script choose the number of cpu cores you want, this will keep those cores online all the time, not just set the maximum amount for cores it can use. You can set it to 1 core only which may or may not be good for battery;) )

To run it, just use terminal emulator, sh /data/media/0/Download/cpuquietandroid.sh (for example)
[LG Optimus 4X HD] Ben36:
So does this have to be done on every reboot tho?

Also... How do I set it to all cores? Change the 0 to 1 on everything?
[LG Optimus 4X HD] JoinTheRealms:
Sorry run the script, assuming 4.4, run "sh /data/media/0/Download/cpucores.sh" in terminal emulator, then enter a number 1-4 (the script will prompt you). if you want to do this at boot, just make or add this to a current init.d script:

echo userspace > /sys/devices/system/cpu/cpuquiet/current_governor
echo 1 > /sys/devices/system/cpu/cpu0/online
echo 1 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu2/online
echo 1 > /sys/devices/system/cpu/cpu3/online
[LG Optimus 4X HD] Ben36:
Ok thanks. I'll give it a try later when I'm home. Over on the nexus 5 forums we've been experimenting set ups you see. Wondering if it'll benefit my missus 4xhd too. We've set hotplug to 0 so all 4 cores are online when the screen is on. But set a low maximum frequency. Then undervolted as much as stable. It's made battery life better and the phone just as smooth and fast as always!

I used to get around 4-4.5 hours screen time and now I'm almost at 4 hours with 23% battery left still
[LG Optimus 4X HD] peppethustra:
Here is a configuration of mine, regarding uV and other kernel settings, which gives me the possibility to gain up to 4 of screen time, and sometimes also better.. I use it with interactive governor, and CPU underclocked to 1300 Mhz, but I think that it can be useful with other governors, too, especially concerning uV:

Here you have a screenshoot of my last usage measuring, with this configuration:
[LG Optimus 4X HD] paolotheking:

[LG Optimus 4X HD] tool_king:
Max. 1 GHz means to castrate your device, so if you want to use it for multitasking as well, it just can't be as smooth anymore.

Without undervolting?
[LG Optimus 4X HD] paolotheking:
No undervolting.
[LG Optimus 4X HD] KrisJoe:
That's impressive since my on-screen time is usually 2 hours or more, but lately it's even less then two hours leaving me no choice and bring the laptop to charge the smartphone while I'm in univ. I'm using one of the latest nightlies of cm11 official, and iodak v9.95, performances are okay with -100mv of undervolt and max frequency 1150Mhz, but it's still disappointing.

Does your rom make that much difference? It's like it doubles the time of on-screen which is impressive.

I'm using Art runtime because I noticed that Dalvik makes the smartphone hotter, so it drains more battery, but the results are very very disappointing and annoying compared to other smartphones, be them with better cpus or slower cpus.

If you like cm feeling, instead of stock, I suggest you to try out a rom based on p880 dev sources (e.g. CM11 unofficial, Beanstalk p880 dev version, Omnirom, to say some names).. I think that p880 dev source, and this amazing kernel with proper tweaks, make the difference..if you like stock rom's behaviour, ask [MENTION=5502051]paolotheking[/MENTION] how to take the nice rom he's using, it's a well made Italian product, and it's not shared here on xda, according to its developer's will

[MENTION=3443693]iodak[/MENTION] Why don't you really try to make your amazing kernel f2fs compatible, at this point? A developer, in TF300T developing section (it's a Tegra3 device), has made it, and it seems to be working with no particular problems:

http://xdaforums.com/showthread.php?t=2625580

To other devs who are improving kernel developing for our p880, if it may be interesting to you to make the point about this, I quote you too: [MENTION=4716493]laufersteppenwolf[/MENTION] [MENTION=4719724]Adam77Root[/MENTION] [MENTION=1149134]Demetris[/MENTION] [MENTION=4582979]JoinTheRealms[/MENTION]
[LG Optimus 4X HD] JoinTheRealms:
My issue with f2fs is there isn't any tools to recover filesystem damage, so there is a real possibility of users losing important files. Otherwise its easy to implement.
[LG Optimus 4X HD] peppethustra:
Backing up important files before formatting everything should not be an option?
[LG Optimus 4X HD] JoinTheRealms:
Yes but thats before the initial format, an example scenario would be, a user formats to f2fs on /data, a couple of weeks later (at this point the user may have forgotten /data is f2fs) the phone randomly reboots and corrupts /data, normally with ext4 android will check and repair /data automatically, but with f2fs the system can only detect filesystem corruption and cant repair it, it will require a re-format, losing anything that may have important on /data (photos etc).

Most users here will make regular backups for sure but im gonna wait for f2fs in fsck before i jump on it;) but my kernel can support f2fs, if fluxs modifed twrp is still up, you can try it out, i just need to recompile if so.
[LG Optimus 4X HD] peppethustra:
Mmm, if it's as you described, it's better to wait another bit of time, you're right..it would be very annoying, to reformat system after a random reboot or after a hard reboot, especially considering that they happen really often to me, when trying to undervolt, or to use some scripts or a patch..this phone never finds peace, when my brain decide to experiment something new on it (often) :D
[LG Optimus 4X HD] ottomanhero:
Could you guys atleast include a f2fs version of your kernels to let users experiment with it?

I take regular backups both on ext sd and on my computer so it shouldn't be a problem.I think that's the case for most of the users.
[LG Optimus 4X HD] JoinTheRealms:
Ill post a f2fs kernel soon, but it will be untested and unsupported;) you will need a modified recovery with f2fs-tools
[LG Optimus 4X HD] raviboy100:
this kernel is great and imho the best so far. however i face ramdom freezes on my phone on an nearly hourly basis. every day i have to pullout my battery like at least 6 times a day

this is really annoying.

[LG Optimus 4X HD] someth1ng:
Honestly, there's a small improvement on battery life but not much. With that said, temperature is much better.

Generally, battery life is only changed by a bit when you undervolt. It's pretty much unnoticeable if you use your phone a lot.
[LG Optimus 4X HD] someth1ng:
I'm getting around 1%/hour drain. That's with 100 baseband wakes per hour.

I disabled WiFi as it causes the WLAN wakelocks. With it on, drain becomes like, 5%/hour or so.

1% per hour is great !

Bring it down slowly, uninstall Words With Friends and Dropbox if you have them.

Use StabilityTest to do burn in tests, when it fails, it will tell you which frequency failed and increase voltage accordingly.
[LG Optimus 4X HD] moss20:
I use dropbox...sorry but what is the problem whit this app ?

However I think that I've already found the maxinum undervolting with my previous settings...I'll try to reduce voltages by 12.5 mv but if I remember well,my phone froze with lower values...

[LG Optimus 4X HD] ottomanhero:
Maybe your ROM is missing busybox? Or superuser itself? Check system/etc/init.d if the app could place it's script.The problem is on your end.

Phone's default frequency is good enough.Underclocking doesn't give a lot of battery.It's only useful if you want to keep your phone and battery cool.So unless you're going to do heavy gaming with an underclocked CPU, you won't even notice the difference.

Overclocking the CPU is also not an option.The battery is about ~43* under heavy usage on default frequencies, so overclocking would just kill the battery.

But 1300 mhz is pretty good.You get good clock speed for low voltage and if I wasn't playing any games I'd use 1300 mhz.
[LG Optimus 4X HD] pheonix1:
I install BusyBox from martket and they shows BusyBox v1.21.1 -kk is installed. And i have Superuser.

In folder init.d is a few scripts
[LG Optimus 4X HD] JoinTheRealms:
Actually [MENTION=5047403]ottomanhero[/MENTION] is semi correct. Init.d support isnt isn't apart of the kernel, rather a small modification to the ramdisk. I forgot iodaks kernels use AnyKernel since v8 (i just checked) which means Init.d support is dependant on the ramdisk that came with the previous kernel install (most likely from a rom install)

Basically if the kernel on your device had init.d support prior to flashing iodak v9 - 9.5, you will have init.d support. If it didn't, you wont have init.d support.
[LG Optimus 4X HD] gingerboy92:
actually, you don't need a modified recovery with f2fs-tools, you only need f2fs-tools binary, which can be put inside a .zip and loaded by updater-script. that part shouldn't be hard. i've tried f2fs on mine, only formatted /data with f2fs, didn't see much differences. it was a bit smoother but not much different than ext4 for me.

WLAN Roaming

Hey, I am on Beanstalk 30/03/2014 grouper version with your kernel and I don't know if this issue is ROM-related or kernel-related:

In my university we have eduroam as Wifi - Many APs and your device should connect automatically to the one with the best signal.

However, it doesn't. Even when I have full bars, the connection often resets itself.

Is this issue kernel- or ROM-related? Can anyone reproduce?
[LG Optimus 4X HD] Rudjgaard:
Another thing you should check for is permissions

When files are placed in init.d they are usually chmodded 644 instead of 755

For some reason the fix permissions from recovery doesn't cover init.d so you must do it manually
[LG Optimus 4X HD] peppethustra:
Maybe the connection has wep encryption, which is no more supported (only WPA and superior are supported, AFAIK)
[LG Optimus 4X HD] Ananasnonym:
Thank you for your suggestion, but it is an eduroam wifi, so encryption is 802.1x, WPA2/AES or WPA/TKIP, PEAP (MSCHAPv2), TTLS.
