hi guys I have been flashing roms since HTC desire days. Got a basic (kinda noobish) question about kernel and kernel scripts.
right now im using Nix trinity rom for my phone which comes with Unity V10 kernel
my questions are:
1.) does a custom kernel use the same CPU values (clock speed,voltage) as the stock htc kernel?
2.) i noticed under rcmix tweaks that there are UV scripts for unity v10. Will these change the default CPU values (clock speed,voltage) of the kernel?

This topic is for my MoDaCo Custom Kernel for the LG Optimus 2x - Enhanced Edition
Features include...
Based on the LG source
[*]Patched to 2.6.32.36
Includes ck2 patchset
Includes optional BFQ scheduler
Includes EXT4 support (with optional EXT4 conversion on install)
Includes CIFS and TUN modules
Two downloads area available, one for users who wish to stay on EXT3 and one for users who would like their device converted to EXT4 on install (without data loss).
r5 DOWNLOAD - EXT4 version (ROMraid Load Balancing) - MD5: 8da29803f1da756706595cfb34d2fbeb
r5 DOWNLOAD - EXT3 version (ROMraid Load Balancing) - MD5: 6f6f78f3f4d2380e5ba85ce6acefe272
Installation should be carried out via ClockworkMod, please do a backup first! This kernel should be compatible with all stock and custom ROMs.
Note: This kernel is already included with MoDaCo Custom ROM Fr5.
Enjoy!

PS I will be posting the full sources on my GitHub in due course.
It's what your "ck2 patchset" and "CIFS and TUN modules"? Can you explain that !?
Thanks.
I will give it a try.
@Paul,
Can you please add overclock option to this kernel?
Paul, could you take the time to add an "init.d" system to the initramfs, this would allow saving min/max cpu frequency (and maybe uv if i get it to work) at boot.
Thanks, and upload the sources one more time
Yup, and yup.

Hello guys!
I am using V10A stock ROM. Could somebody tell me advantages of this kernel compared to stock kernel 2.6.32.9?

+1. Yeah are there any benchmark changes and so on in this new kernel? Also are there any bugs in this kernel like browser lags or something?
Hi,
Thanks for this Kernel, Cifs support changed my life
However I sometimes have some big lags. Phone doesn't response for 30 secondes or more. Even sometimes i have to remove the battery to reboot.
I had not noticed this pb with original Kernel.
Am I the only one having this issue?
Is there a new version of this kernel available?
Thank you
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.
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 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.

Have you noticed any radical changes replacing stock rom kernel with Semaphore?
No,not radical improments,but there is some benefits,like semaphore control app.where u can tweak kernel to your liking.
Try it.u can backup your existing kernel with k-tool or sgs kernel flasher
hi everybody.
I've a very deep question: what is the best kernel which I can use on V30B for improve battery life?
thx
I'm not sure what you are asking, titel of your thread don't really fits what you write.
If you ask for a kernel for IceBOOM from rrgrrg as he said in his fist post http://forum.xda-developers.com/showpost.php?p=35225392&postcount=1 the kernel from Gawbeakz (V30i Kernel). I don't think there is a other kernel as the one it came with, GB kernels will surly not run with it and ICS kernels probably neather.

Grazie Pado (thx Pado), but I've found some battery drain problems. BTW I flashed ZG rom yesterday evening and it is very fast and smooth. I'm really surprised by the work done from Andoiib, hence I will keep that ROM untill new Zeus (if it will be better than this one)
thx
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 !
