So, this doubles as a root kernel (might as well keep the scripts in there since I already made 'em!), custom boot animations (/system/media/sanim.zip), init.d support.

Max speed is 1.94GHz. Max speed I've benchmarked stable at is 1.83GHz. Reboots at higher.. YMMV with voltage adjustments etc.

Stock speed on this kernel is 1566MHz, I have removed a lot of scaling overrides that Samsung added, so this should be a bit smoother than the stock kernel without OCing more than the slight default.

GPU is also OC'ed from 3d speed 266 -> 300 and 2d speed 200 -> 266.

I will be releasing a GUI soon with more advanced tweaking options for the kernel (it is compatible with existing tools like system tuner, fauxclock, setcpu, etc.)

CWM Flashing Instructions:
CWM Install Instructions said:
1.) Install CWM from http://xdaforums.com/showthread.php?t=1517134
2.) Copy the cwm zip to your /sdcard/
2.) Reboot into CWM either by issuing "adb reboot recovery" from command line, or loading ROM Manager app and choosing "Reboot into recovery", or by powering the device off and holding vol up+vol down and powering on.
3.) From CWM, choose "install zip from internal sd card" then navigate to the cwm zip you copied in, select it
4.) Select "reboot system"

You can find the Odin tar here, follow the flashing directions from my Root kernel here

You will need modified libraries to take full advantage of this kernel as they override speeds at times, you can find these here.

You'll have to push them over adb for now after flashing the kernel, when CWM is up I will make a CWM zip for it.

From the directory with adb and the three .so files:

Code:
adb remount
adb push libhardware_legacy.so /system/lib/
adb push librpc.so /system/lib/
adb push libandroid_runtime.so /system/lib/
adb shell chmod 0644 /system/lib/libhardware_legacy.so
adb shell chmod 0644 /system/lib/librpc.so
adb shell chmod 0644 /system/lib/libandroid_runtime.so
adb reboot

straight fire... phone's not even officially released and everything needed for awesomeness is available.

are the .so files located in the boot.img file? Or am I missing them somewhere in the .tar file?

Thanks for all your hard work.

You are a beast man.

I havent aquired a note yet but i am curios...CIQ present? it is one of the things I failed to check for when I had one in hand

Flashed, libs pushed, and ready to roll! Woot woot! I'm so glad that i got my phone a day before most everyone else, muahahaha!

EDIT: HOLY CRAP ON A STICK. I laugh at the Engadget review that told us the Quadrant score was lower than the International model. This was at 1.83ghz, performance scaling.

I use on-demand governor, also 1.83Ghz. Hope this doesnt rape battery. Would be nice to have some static undervolting or even better - HAVS. SBC for the battery could be awesome too (am I getting greedy? lol)

How nice, these scores are the same or better than int version most with custom roms and kernal. Good job man

    I never learn my lesson about providing an ETA, keep slipping! I've got BFQ, CFQ, smartassv2, etc. etc. in now, just dotting some i's and crossing some t's.. coming soon! Lowered some default voltages on the higher end of the scale (1.89+) also since some people have reported stability at lower voltages at those speeds.

    sgs kernel flasher will work if it read/writes to mmcblk0p8 (which is where the kernel lives on our device)

    Updated first post with CWM zip including libs so you no longer have to push via adb/odin. Will update shortly with a return-to-stock CWM zip.

    Long weekend.. working on a new build now ;)

    HAVS is actually already built into the stock system. It scales according to demand from 3 separate units (the memory/bus subsystem, the GPU, and the CPU(s) )

    The voltages you can set in system tuner/fauxclock/etc. only apply to the CPUs, once my app is out you'll be able to adjust GPU and L2 voltages/speeds as well.

    The other governors etc. are coming shortly.. hopefully tonight ;)
