Hai,
I just updated my O2X from 2.3 to Android 4.0.3, and CM9.0.0-RC0-SelfKANG3-Optimus2X. I've restored setCPU via titanium backup, and i cannot set scaling governors in main window. It looks like screen that i've posted in attachments.
To be sure, thats its not becouse of kernel that im using, I've checked file that show available governors ( it shows 2 - performance and powersave).
I'm curently on ironkrnL48-20120218h2043_ics kernel.
I've tryed CM9 KANG1 rom, and problem exist aswell.
ps. Which kernel you recommend with this governor, that rapidly increases CPU clock when needed? :>
// i tryed to google this problem, and i didnt find the answer.
thx.
Governors are useless on our phone, Arcee stated it long ago in CM7 threads, and had be confirmed by many devs.
So don't bother with governors, as we lack specific NVIDIA sources to recompile kernel with proper governors (and other that exists on other CPU), CM9 kernel is only a hack between GB kernel and Android 4 sources.
There is Ironkrnl work for P990, and faux kernels for P999.
Also, vadonka is working very hard on his ICS version of ETaNa Kernel. So in the near future, we will have another kernel to choose from.
So just use SetCPU profiles
selfkang2 + 48mb ics kernel gave me random reboots after battery went below 50%

The same happened to me on temasek's 204-67 CM7 kang. On 204-66 I had two governors available in the drop-down: performance and powersave (if I recall properly). Now the dropdown is just empty.

I confirm - I flashed new kang but left the same kernel as before (vadonka's ETaNa-REV1, 18FEB one). So it seems that something changed in the system, not the kernel.

I followed the instructions here to install my CM9. SetCPU seems to work fine for me. Maybe you can try the kernel that's included in the instructions.

Hi I'd like to clarify something.
I've used CF autoroot to get root access, which means I have stock ROM on. I've read elsewhere that in order to undervolt, you need to have a kernel that supports it. The stock ROM/kernel doesn't support undervolting right?
So if I want to undervolt, I must have a different kernel?
yes
Perseus Kernel allows you to undervolt
perseus like stock kernel !
What settings do i have to configure inorder to make cpu scaling less ( sampling and more specifically cpu freq changing )
.. and make it behave more like stock kernel ? ... i only need undervolt! and rest same as samsung defaults !
It seems the Interactive governor is not included in the stock kernel. Does anyone know if the kernel supports it and how do I install it? Thanks!
So for the first time I have not had to use any kernel tweaking apps like kernel auditor. However was considering trying to use kernel auditor on a stock rooted rom. What are your views please and how will using kernel auditer play out with Samsung, s own inbuilt performance and gaming settings?. Also those using any kernel tweaking apps, have you noticed any performance boosts as that is my main priority performance thanks.
I understand we are not able to flash any custom kernel since there are none available with this device having limited dev support.
However, if rooted can we change settings with a kernel manager with the CPU and GPU? Installed EX Kernel Manger and set the CPU governor to "performance" but not seeing any speed or performance increases
