what does that mean(sio, deadline etc..) .......... also i'm on ardat's kernal 1.7 ........ oc it to 1.2ghz......

is SetCpu application makes our SGR hotter ?? i mean will the temperature of the phone will be increased ???

If you overclock using any application or set a high cpu clock speed for constant use like min max 1200mhz then yes, you will slowly cook your phone.. But if you set the values properly.. Then you'll get a hell lot more battery life..

additions
5 cpu frequency
KERNEL#48
removed unstable 468mhz
undervolt integrated

now works on jellyblastv3
back on proper 4 cpu freq
KERNEL #53
back to the stable 4 freqs
added ext4 support
added swap support
added boot splash
smaller kernel size(using lzma compression)
312mhz boot now fixed
lionheart, interactive govs built in (disregard metaphase gov its a fail)
can run flashplayer on our phone
only 1 bug 312mhz cant go down to 156 and vice versa must be on 624 or 832 for it to ramp down to 156 (fix coming soon)

known bugs
1.INCOMPATIBLE with JELLYBLASTv3
wont boot and logcat show no such file or diretory /system/xbin/busybox(but i checked it busybox is there)
2.HYPERION ROM-reportd by vanhalen35
battery charging wont reach 100% when using setcpu stucks at 99% but unistalling setcpu and rebooting it charges up to 100% dont know why but on my ussrv6 it charges just fine up to 100%
3.#39rev1
468mhz isnt working properly yet
4.#48
kernel version shows up as unavaiable under settings>about phone>kernel info .but is seen using cpuspy
startup is laggy due to it boots up using 312mhz
5.#50
CPU states cannot be read except for deepsleep
still laggy at booting but after a while it is fine
728 is not stable, the rest seems fine need verification from you guys
6. #51
still havent solved the cpu booting at 312mhz
7. #53
312mhz cant go down to 156 and vice versa must be on 624 or 832 for it to ramp down to 156 (fix coming soon)
just report anyother bugs you encounter

Studied & Picked up few sources from git's ... And just figured it out that every clock speed has been assigned a specific voltage so out of trial and error method i found tat the more i undervolt the system seems to lag .... So when i got a stable system i compiled the build.... U can also say that the undervolt is still in beta stage cause u never know if the scaling set is correct till u experience bugs but...so far so good i've been gettin a stable result :fingers-crossed:

But I read that scaling differs from device to device?
Just like oc, some devices can handle more, some less...
System lag is bad news though...
Will make uv pointless, and also the time I would have spent improving the way...
What about uv+oc?
"By the power vested in me, I now pronounce you, Man and Knife"

yup scalin of frequencies differ from device to device nd that is y i've used sources from tj_style's git .... i would still hav to concentrate on OC + UV together cause it needs lots of testin .....

My review:-
Firstly a claps for you yajnab..
Kernel is fully loaded with features ..no bugs at all...BEST battery backup kernel ever on gb..i used ur kernel in hyperdroid v1..jana v6.7..stock rooted and its still counting..ur kernel has best performance tweaks...i used it on my custom rom then it gave me about 18hrs of battery backup and speedy tranfers & i was totally gone mad.. keep the good work goin for gfit bro..
I suggest evryone shud use kernel once and i definately can say u will fall in love with it..
keep updating bro..

Is the kernel overclockable? If yes den how much?

ntfs supports is easy. I started it sometimes ago.
-Config kernel support ntfs read and write
-an initd script to mount ntfs on boot
-ntfs-3g binary
-Better should repartition sdcard, atleast have 1 FAT partition or android will mess up
All can find in SGS2 forum

No overclocking ... I hate this overclocking stuff..

But apparently the people who might want to try your kernel like overclocking their device.. Anyways no problems :thumbup:
