if you have CM, you can use setcpu or no frills to change the io scheduler but available io schedulers will depend on how the kernels were compiled. I just use the default which is sio..

I built this kernel for my daily use, now i decided to share it here!
Work with Nexus World Wide Version (i9023/i9020t).
※ Basically it is made for Official Stock ROM (JRO03E/JZO54K). it may NOT work with other ROMs.
Not working with CyanogenMod!
Main features of this kernel:
1.25GHz
Based on Linux Kernel 3.0.73
Based on AOSP
Touchwake ADVANCED (allowing you wake up your phone by touching screen when you got a notification ) (based on Ezekeel's work)
10-point multitouch
Force AC charging by chad0989
UKSM (Ultra Kernel Samepage Merging)
MTP (thanks to bedalus and Krarvind!)
High Bigmem
BLN by Ezekeel
BLD by Ezekeel
Powerkey Presses Counter
init.d support
Optimized CRC32 algorithm
SLUB
Custom Voltage by Ezekeel
mount dalvik-cache to /cache
undervolted
RCU Boost
Voodoo by supercurio
included busybox
USB OTG v5 by sztupy Read this. (not sure if this work on Jelly Bean)
CRT-off animation fix from CyanogenMod team.
PM_FAST
...
Default: interactive / sio
Thanks to all contributors of this kernel!
And welcome to fork it on my github.
Download vta2-kernel / Changelog
TODO:
Bluetooth battery drain fix.
ROW I/O scheduler ( kernel module )
...
Any Suggestion? Tell me here
hi crt is fix ?

Can you make a version with also fast charge? Anyway working great

I'd like to see more feedback about this kernel as it looks promising. Thank you
Sent from my Nexus S using xda app-developers app
Kernel is good.. snappy.. nice performance..
There is no 1000mhz on the clock, so it's always on 1.24ghz ..
Pls add interactive governor.. I can't change the governor, only shows smartassv2 ...
Battery life not gr8.. But runs well.. power hungry games are smooth.. good overall..

This is inspired by SAMSUNG Infuse 4G, which use the same CPU and do not have 1.0GHz step in its stock kernel.
when there are both 1.24 and 1.0GHz, the governor will prefer to use 1.24GHz. And i thought it may help governor switch between steps faster.
so it won't eat more battery in this case.

I only built smartassV2(tweaked) into kernel. because it balance between battery life and performance.
There are also include kernel module of ondemand and conservative, you could load them by insmod if you like.
Thank you very much and must try it .

thanks for your kernel! i will try it now and report back
EDIT: unfortunately kernel doesn't work for me - i use it with paranoidandroid and rom was really sluggish at first (maybe cache-related...). then i startet setcpu for adjustments and the phone stopped responding with "colorful snow" on the screen. i pulled battery to reboot. - maybe my 9023 doesn't like 1,24 ghz (it is a bit picky, but 1,2 ghz at stock vol was never a problem).

@OP or @DaXmax: Is there anything I can do to help at finding the problem? logcat? or is it just my phone being picky?
Deep idle? Are u sure it's fully working?

I may replace deep idle with CPUidle or IDLE2 by _thalamus in the future.

yea, well, with stock kernel (and thalamus and matr1x and air kernel) everything runs fine, but i wanted to know, if there is a way to find out what exactly causes the problem with your kernel and my phone (which also might help somebody else). - raising the vol does not help that much, still some freezes from time to time (even though i'm above stock vols).
Hi. I want to know if there's any way to flash new governors and I/O schedulers to my phone. I have a Sony Ericsson Xperia W8 (same as X8). I tried searching XDA as well googled it but couldn't find anything on this topic.
I am running Alfs kernel v09c with MiniCM7 2.2.2. It doesn't have Smartass H3 governor and Deadline Scheduler. Both are my favorites. I like this kernel as its very fast but doesn't have this governor and scheduler.
If there's a way to install/flash them kindly tell me and also provide the necessary links.
Thanks a lot
alot of ROMS present which one is best keeping in mind just pure gaming.....

Only one updated kernel we have is CoCore, so it is best one. ROM, maybe HarshJelly/SamiOS for stock, or some CM (I think CM10.1 is most stable of all we have for now).
I used thunderzap 4.1 with jellymod 4.1 and was pretty dissapointed cuz games were not smooth...I will try Roms u mentioned...

I/O scheduler & CPU governer definitions?
Hi
Can someone please give me the definitions & the best combo of I/O scheduler and CPU governer? i don't understand what do they mean exactly.

Checkout this two threads:
- CPU Governors explained in detail
- Brief info on CPU Governors and I/Os
Hi everyone
I was wondering what is the best cpu and i/o combo
I am currently on Cyanogenmod 10.1 RC4 by bieltv.3
Max Cpu - 902 Mhz
Min Cpu - 245 Mhz
Governor - Smartass V2
I/O - Deadline
Any opinion guys???

Overclocking can fry your cpu. My governor is smartassH3, frequency 245-800 MHz and I/O is sio. for SmartassH3, flash MA6 kernel by @Mardon. Btw just curious, why are you using an old version of cm10.1? there is a final version for cm10.1. here- http://jenkins.androidarmv6.org/job/android/602/

Thanks for your reply -BRK-, but im comfortable with 902mhz
I'm also confused whether i'll use sio or deadline I/O

Ohhh... srry for being noob and all. It kept on rebooting after i set the clock to 902mhz
so i stick to your advice
Max-800mhz
Min-245mhz
Gov.-SmartassV2
I/O-sio
