[Q] ICS, Acer E330, stock kernel doesn't want to cooperate - Android Q&A, Help & Troubleshooting

i have searched and re-searched a lot of times for threads that talk about my same problem, but none of them is related to it in terms of phone, kernel or ROM, and they're all nearly 2 years old
in addition, i am new to this forum, so please don't shoot me
anyway here it is:
i've tried almost every existing method to get governors like smartassV2 and interactive (my favorites) to stick without reverting to ondemand, but none worked
i noticed this:
in the exact moment the screen is locked, something sets the governor to ondemand
in the exact moment the screen is UNlocked, the same thing (i guess) sets it to performance, then to ondemand
since i know a bit about intents and receivers, i can say this behavior is triggered by android.intent.action.SCREEN_OFF/ON intents, so there must be some system apk with a receiver for those which reacts and changes governor accordingly
right now i'm running a modded init.qcom.post_boot.sh that sets back the governor to a custom one (i.e. smartassV2) every 20 seconds, which is the only way i can get it to "stick", however i hate this method 'cause it implies there is a shell running in the background, thus stealing some (yet minimal) resources and battery, and the problem is still there
some info that might come in handy:
phone: Acer Liquid Glow E330
ROM: Glowing Liquid 1.5.2 (ICS)
kernel: Lupo's kernel V3
take a look at the logcat screenshot attached, i think i found something but i have no idea what to do
EDIT: if you can't read what's in the pic, it's saying something about a CpuGovernorService

how is it possible that nobody cares? i've given more info than anyone else on this problem people, experts, devs, anyone, say sumthin'

---

Maybe try tot set it with an app like trickster mod and set it on boot? Or try another ROM to see if its a system app. Sorry I dont really know the programming part..

i'll disable my script and give it a shot, however there is no other ROM, only two existing alternatives are stock (which only has crappy ondemand) and glowing liquid by vache
EDIT: didn't work dammit

UPDATE: by raising the log level to 7 in a custom boot.img i can now see PrintK saying this:
cpu_policy->user_policy.governor name interactive, str_governor = ondemand
update_cpufreq_governor cpufreq_update_policy return = 0
as a linux user, i know that PrintK is basically the kernel talking to the user/log daemon, so i am now asking help to kernel developers for any clues about it, and maybe how to change that parameter (or whatever it is) in the kernel to get rid of ondemand
as difficult as this can be to figure out, i'm sure that this would be the end to many headaches, so anyone who knows about how linux kernels work please help me find the solution to this thing

hello , i got the same E330 , stock rom but root and kernel LupoV3 , to set it at 1300 mhz and SmartassV2 , maybe try Android tuner , or some who got possibility to change CPU with screen on/off , i'll try to see ...
Vache did a release 1.6 of this Rom , and Acer too (Acer_AV044_E330_1.041.01_EMEA) you can found them at Acer-club.fr

If you look closely, it resets to ondemand every time the screen changes state

EDIT: the thing is, i do have a cpu tuner with wake/sleep profiles, i simply can't seem to have it doing its job
also i stick on stock kernel because the other ones have buffer problems with music, and i'm not sacrificing my flac files for
crappy mp3s

is it this one ? "CPU tuner (Rooted phones)" on play store , i give it a chance yesterday and it looks to do the job, more than nofrill etc .... no easy to set fine but if i see the log file 'journal' it works , i come back to "smartassV2" (wich is "virtuel" gov settings) after wake up and at enter calls ...

No, just the setcpu implementation in rom toolbox. anyway i tried that "cpu tuner" and it kept forcing the governor to ondemand despite the "normal" mode being set to interactive (and yes, "normal" was the current setting)
