Looks really tempting. Let us know how batt life is holding up after a cycle or two.

@DAGr8:

I don't know if it works on the Rogers version yet (it should)

I would recommend flashing the modified recovery, then booting to recovery, connecting via adb, and dumping the stock rogers kernel via the instructions in the post. I can use that to determine if the kernel will work well or not (and that'll give us a stock rogers kernel to revert to later)

Re: battery life: Seems pretty good at 1.83ghz, full screen brightness + playing music + surfing the net for 40 minutes dropped me to 86%, quite a bit better than skyrocket would have done under the same circumstances with a lower overclock!

Awesome

Awesome work Da_G. Is it possible to build in cifs support into this kernel for mapping over samba share to access NAS? Thanks!

yea , unless someone beats me to it .

moving to the note /lte network means I have to leave fido (current provider) and go to rogers , I just gotta double check what months have been paid so I dotn double pay anything . Chances are I upgrade within next 24 hours = gf going to be mad at me for spending all that time on the computer again .. lol

side note wanst there a way to prevent that kernel counter from doing its job on other devices ?

Outstanding sleep on this kernel! Didn't get it with stock or your other rooted kernel. :)

Da_g your Oc brilliance set my a mind aflame! Gathering up my limited linux, ancient msdos, and trembling fingers i successfully installed your monstrous brainchild. It was feat that left this xdaer in a cold adb fear sweat.
Speaking of beer, I figure I owe you at lest two, if just for the rush. Damn, I love this stuff. Thank you! 8UX55289XR629391F

    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.)

    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"

    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 ;)
