Hi devs,I have a problem,i have a huawei u8650 and a custom kernel with overclock support,the normal frequency is 250-600 mhz but when i overclock it ,for example to 768 mhz,the camera starts to give some problems,some black lines appears in the screen and the pictures taken have those lines too.
I think that maybe the problem is the voltage, i ve downloaded some apps from the market to change voltage values but they tell me that my kernel doesnt support undervolt or overvolt,so i need help to ad that posibility to my kernel.
or give me please some posible reasons why camera act different when doing overclock?
i have descompressed de boot.img and have the boot.img-ramdik folder and zimage inside a .zip atacched if some of you could help me.
thanks i advance.
no body?please i need to solve this problem.
the github to the kernel is this https://github.com/supertoast/kernel-2.6.35-series-U8650-U8510-M865-Gingerbread
If I were you, I would not UV...
But to be honest, I also dont know how to

hi.. i need some advice/guide regarding this matter..
first of all, i'm planning on compiling custom kernel myself for my ace. i've succesfully compiled a kernel on my debian box using kernel sourcecode from samsung and also applied bfs patch. but now i dont want to just stop here.
the problem is i dont know where to look for those undervolt patch, smartass governor patch, interactive governor patch etc etc. gooling for "android kenel patch/module" just bring me to precompiled kernel thread, not the source patch itself. so maybe anyone can guide me the right direction? thx before

better to see the github site, lot of kernel source with many patching in there. and i think, for the much customized of samsung kernel, you can just patching, manual diffing will more better because samsung kernel is not vanillaish android kernel. much modification in there.

Custom kernel for the Ace on it's way..?
Hi all,
So far, I am able to build a kernel from source for working on Dell Venue. As I notice, the JW rom has performed some overclocking tricks to reach a CPU frequency greater than 998MHz.
I would like to ask, how would we overclock for Dell Venue in our kernel? I tried to set min/max frequency for CPU manually, but no effect (the kernel documentation also shows that, Sysfs can override such change).
Please help!
OK, now I got the answer and know where to patch.
BTW, my topic was moved to General, it might not a suitable place since I am asking about kernel tweaks for performance, not using apps.
So r u building a new rom? might be ics 4??
Hi folks,
the last rooted ROM at the moment is 4.0.26 which surdru_petru rooted for us, thanks !
Unfortunately surdru_petru had to change his device
He also left a 3.0.21+ overclocked kernel which was needed for 4.0.25.
1. Can I use this kernel also for the 4.0.26 without loosing improvements done by Archos on 4.0.26 ?
I have a Archos 80 G9 with a OMAP4460 ES1.1 on 1.2 GHz default clock.
Can anybody give me detailed hints how to do a overclock myself (nevertheless which Archos ROM to be used) ?
I read aboud a thread win tun.ko . Maybe it's the same way sudru_petru did the overclocking ...
2. Can I extract kun.to file(s) from sudru_petru kernel 3.0.21+ and copy it to my 4.0.26 (or maybe also later roms) ?
I also read about a possibility to patch configuration parameters of the Archos in order to do set permanent max. clock rate (e.g.1.5GHz for my device)
3. Did anybody this patching for a Archos 80 G9 with OMAP4460 ES1.1 ? Which adresses to be patched with what value ?
Thanks for reading and maybe some helpful comments
Cheers

The over clocking is applied to kernel on the source, so you can't just simply patch it to ROM.
As far as I know, 3.0.21 over clock kernel should work on 4.0.26. All the changes that are on the system will be kept, but you lose kernel changes. I believe most of the changes are on system, and will stay because of it.
Tun.Ko is a module required by vpns, like openvpn.
"The tun.ko file is a device driver(module) that provides packet reception and transmission for user space programs." Source: http://droidvpn.com/page/what-is-the-use-of-tunko-1/
In over clock kernel you can rise your clock speed, but it won't be permanent. I haven't heard of a patch like that.

In the first link, it has overclock kernel with tun.ko support, but not overclocking by using tun.ko.
The second link might work, but I would personally prefer the kernel method. But it is your choice if you want to "fake" your device.

I have a device which is from hardware point of view the same as the 1,5GHz turbo version.
The nicest thin to do would be setting the flag(s) from a 1,2 GHz to a 1,5GHz model so I don't have to care about OC versions anymore.
Just need a rooted ROM ...
So it seems that anybody would share their experience concerning the second link ?
overclocked 4.0.26 with tag file
With the kind support of scholbert I have now oc my Archos 80 G9 OMAP 4460 ES1.1 8GB flash 512MB RAM from 1,2GHz to 1,5GHz by just setting a flag in the tag file.

But beware !
You may brick your device permanentely !
is there a kernel with cpu (~1,5GHz for cpu and maybe gpu oc?) for cm11 ?
i really want to oc my sola.
thanks in advance
no sadly there is no way to oc it in cm11 because it may lead to bricking the device if you installed the wrong one i am sure they are working on it you can always see performance tips and build.prop tweaks for insane performance here is a nice one http://forum.xda-developers.com/xperia-u/general/tweaks-collection-build-prop-init-d-t1709836
press thanks if i helped you please
hmm now i just have to wait or better try it by myself ...
but...i know mali drivers are opensource and it is oc'able but what about ste? is it still more than less closed source??
ps at the moment im on cm11 with a pair of tweaks but my sola cant play a song on soundcloud...when i go to recents it stops... -_-
pss i cant run a full antutu test...the app dies when it comes to 3d test any ideas ?
Hi I'm trying to undervolt my mido and does anyone know how to understand the files in arch/arm/boot/dts/qcom controlling the voltage ? I know there are already custom kernels with undervolt but I can't seem to understand how they did it by looking at the git commit. And I would want to undervolt my device as much as possible so I would have to use my own kernel
