[Q] Kernel for CM7.2 Stable that allows OC and governor change

I have just updated to Cyanogenmod 7.2 stable on my P990 Optimus 2x (Fido Canadian version).
When I go to the CPU settings I cannot change the min/max frequencies or select a CPU governor.
I have done some research and found kernels like Vork and FauxDS, but they are for 7.1 nightlies so I am not sure if it is a good idea to flash them.
What I am most afraid about is the possibility of getting the black screen of death while my phone sleeps (it happened once already but it stopped after I changed to a different charger and reflashed CM7.2).
The reason why I want to change the settings is that there tends to be scrolling lag (my old HTC Desire Z was faster!) and there is also a bit of lag waking up the phone (lockscreen does not appear instantly when pressing power button).
Does anyone know what is the best kernel I can flash to enable frequency/governor changes in CM7.2 stable? I would prefer not to change the ROM if possible as I am kinda nooby in comparison to the XDA community in general. Thanks for any help.

I suggest you try Etana kernel. It has the things you need. Also use CPU master to set profiles and minimum CPU frequencies. I used something like min freq 352 MHz when asleep (don't worry doesn't drain battery) and I had no lag whatsoever.

Are you referring to http://forum.xda-developers.com/showthread.php?t=1427646 ?
If so, do I just flash the zip off the sd card using ClockworkMod? And what are the differences between lite and DS?
Thanks.

All right, after reading, I determined I don't need LOC/HOC/DS as I don't intend to raise the max frequency, I just want to raise min frequency.
Installed the Etana kernel via CWM and it works. I can raise minimum frequency, though I still cannot see a governor option! Any idea how to get my governor setting back?

You can use CPU master and set some profiles. It's not exactly the same as governors but it's as close as it gets and it gets the job done pretty well. As far as I remember there were two governors for O2X - powersave and performance. I've always used performance and I can't tell if there's a HUGE difference in battery usage. I guess performance utilizes higher CPU frequencies when the device is asleep and somehow scales faster to even higher frequencies when needed to. But this might be complete crap as I am not too much into how CPUs work...
And please use the THANKS button (right below the user name), it kind of forum etiquette and it keeps people motivated to help others. Thank the Etana developer too.

Thanks for letting me know, I didn't realize there was a thanks button at first haha.
Fixed!

As for now CPU Master in his profiles let's you choose governor. We have only 2. Power save nd Performance.

[Q] Havy Battery Drain on [ROM][4.4.2] CyanogenMod 11.0 20140315 [DAILY] [FULLY WORKI

HI I am having heavy battery drain
running version from 15/03/2014
I had a maybe 3 minute phone call but still the phone app has eaten up 37% followed by 31% android system
total 72% left after 1h36min
This is a new behavior, up to last week it all worked smooth.
the CPU governor in nofrills CPU is now set to performance since on demand or power saving make the phone very sluggish
Also Video app is not working, just crashes same result in Focal
Any ideas or tips?
Thanks Merlin

You do realize the performance CPU governor makes the CPU constantly run at 1 GHz? This will of course drain your battery.

It's maybe the 1GHz bug. The 1 GHz bug cause the heavy battery drain. Try this, turn off wifi and reboot.

its 1ghz bug if you are using ondemand. but i hope you know performance governor keeps cpu freq. at 1000mhz.
im using abbysplug/sio governor. and my battery lasts for 18 hours.(wifi or mobile data on. sms Messaging. whatsapp. facebook games rarely)

abbyssplug change the processor performance. You can find it in Settings > performance > processor > CPU governor

go tp settings>about phone and press repeatly to build number. you will see "you are a Developer now" text. go back. performance menu must be appear. you can set it there cpu governor.

A fellow user thankfully redirected me to this thread and told me about this governor setting you mentioned above and i must ask you some questions if you dont mind of course
1- What's the difference between Abbysplug and Powersave governor? I have my phone underclocked at 200 at all times and the sluggish speed never seemed to bother me much, so is there a difference between these 2 governors when it's at 200 all the time?
2- Have uninstalled/frozen/disabled any system or built in apps?
3- You leave the mobile data on for 18 and the battery lasts????
Please give me your exact settings, man; i'm desperate. :crying:

LG P990 battery drain when the overclock to 1.4GHz

LG P990 battery drain when the overclock to 1.4GHz.
I think the kernel I used support overclock to 1.4GHz. But it happens that battery drain so serious that I cannot even charge the phone?
I am using LG android 4.1 rom. Anyone faced similar problem and know how to solve? thanks

Its known that higher OC = higher drain. But the drain shouldnt be so much massive.. Try to check with BBS what OS using your battery..
Sent from my LG-P990 using xda app-developers app

thx for suggestion, I am now using BBS to check battery state.
But the most weird thing is that, if i stick to no overclock, the battery life has no problem.

BBS result: I found that if i overclock, the mobile cannot deep sleep. Or in fact, if I overclock to 1.3GHz, set as interactive mode. The CPU keeps at 1.3GHz for most time.

So that's your problem.

Use trickster mod app and set min/high frequencies and on governor control setting choose on over which load your cpu will go on high/max frequencies....

I guess i find the problem.
The media server is draining the battery.
As far as I did not listen to music, it is ok.
But if I use EsExploer or playerpro to play a music for an hour. The BetterBatteryState showed that the CPU freq keeps at 1GHz for an hour.
What can I do to solve the problem? I googled a lot, including "repair" all music on sdcard, etc, many so called solutions did not solve the problem. thanks

[Q] CPU frequency adjustment problem

Hi guys
I used most 2 reliable apps ( Pimp my z1 & Performance Control ) but I have problem on both adjusting cpu freq . for example when I adjust the min on 300Mhz it will return to the default ...
what should i do?

Have you got kernel support to OC/UC?

Yes! Using doomkernel v21... When i go to cpu control in pimp my z1 and adjust the freq, for example i change the min value from 1190 to 300 then save it,and press the back button and when i come back its again on 1190 or sometimes its higher. Now its on 1728 on min and Nan on max.
Have the same problem with the performance control too..
P.S the battery drains so fast too,the upper part of phone is warmer even when i'm not doing anything heavy. Editing this post got 3% battery! Using iHackers 4.1

1GHZ bug in stock ROM?

The last days my girlfriend is complaining about battery drain in her i8190. I installed No-Frills CPU and it seems that the min CPU frequency is stuck at 1GHZ. Applying the 200MHz setting does nothing, when i restart the app i see that the min freq is 1ghz again. The phone is with stock rooted firmware (XXAMJ3).
Any ideas about this really annoying problem?

Tell your girlfriend, she should reboot her phone with Wi-FI OFF. This will solve the problem

Did you or your girlfriend change the CPU governor to performance? No-frills CPU control can change the CPU governor. Try it out
Or
Set the phone in airplane mode and reboot the phone if it still didn't work then please attach/send some screenshots from the battery statistics in settings > battery in this thread.
P.S : Download "CPU spy" from play store and check if only 1GHz is in use.

She hasn't change the cpu governor (was with ondemand). The trick with airplane mode didn't work either!
These are two screens from no frills and cpuz where you can see the problem. I checked yesterday the real battery performance, it didn't seem that bad. Was 100% to 35% in about 9 hours with 2 hours screen on time. But isn't that strange, the min freq bug?

that is an unnormal behaviour. I think it is app-related.
try THIS to see which apk´s wake your phone up.

I installed wakelock detector but i don't see something strange.
Really frustrating, i can't find any solution!

noLED 107x (a playing tool in my opinion)
Handcent 104x (stoneage)
... many wakelocks
btw who uses sms in this time ?
use threema and greenify noLED
m.

if you still have problem try to change govenor and i/o schedular then switch wifi off then reboot.
