Default [Kernel] [Sprint] [1.4/1.2 OC] Bauxite Kernel - 2/12/11 -V3.3

Extremely Alpha Code

Hey everyone...

I've developed what I think is the first 1.2ghz overclock for the Galaxy tab Sprint ONLY.

WARNING: THIS KERNEL MAY NOT WORK ON YOUR DEVICE, MIGHT DESTROY YOUR DEVICE, MIGHT PUNCH YOUR CHILDREN, I AM NOT RESPONSIBLE FOR ANY DAMAGE CAUSED BY THIS KERNEL, USE AT YOUR OWN RISK

Whew... now that the warning is out of the way I present a 1.4/1.2 overclock based off of the details here:

http://forum.xda-developers.com/showthread.php?t=943669

Quadrant Score: 1129
Linpack Score: 19.29

You will want to unpack the zImage and push it over with Heimdall, while in download mode (hold down power + vol-down until you get the download mode screen).


FOR OTHER DEVELOPERS
------------------------------------------
As I stated before, if you follow the link above and modify the exact same lines you can add this to you kernels as well.. however the file names are different, the files you want to modify are..
arch/arm/plat-samsung/max8998_consumer.c
arch/arm/plat-samsung/s5pc11x-dvfs.c
arch/arm/mach-s5pv210/clock.c

The last one took me forever to grep and find...

This is just the first of many versions, I will look into other CPU frequencies and voltages, lets see how far we can push this baby.

V3.3 --- EXT4 ONLY Kernel... only use this if you are on ext4

V3.1 --- Fixed Ext4(?) NOPE

V3.0 --- Based on EA24 Source - untested with older software. Adds EXT4 (broken)

V2.0 --- 1.4/1.2 GHZ OC, reverted previous changes, NO EXT4 (yet..) ONLY FOR SPRINT, USB FIXED - based on koxudaxi's patch
You'll want to use the voltage control app here:

http://forum.xda-developers.com/showthread.php?t=943669


V1.2 --- 1.2 ghz OC, 1.35 Overvolt (for stability), ext2/3/4/rfs
V1.1 --- Added 1ghz back in as a choice, reset your setcpu to select it.
V1.0 --- Added 1.2ghz overclock (replaced 1.0ghz default, will fix later)

Testing now but awesome work!! Works like a charm! I would take it it would run stable about the same speeds as the other Hummingbird processors at normal voltage ( 1200 ) and lower voltages at 1440 just fine but who knows

This is with this Kernel and OCLF.

How about just setting #define USE_1DOT2GHZ 1 in s5pc11x-dvfs.c and in linux/arch/arm/mach-s5pv210/cpu-freq.c?
That should switch everything to 1.2GHz tables that Samsung nicely prepared for us?
it seems to work for me just fine.

Are you sure it works without altering clock.c? Until I changed that file my device was reporting 1.2ghz but it was still super slow.

EDIT: nvm, you're right. Changing that would change clock.c as well. I don't plan on using the default tables, but it's a good place to start if you want to stick to default values. I know this thing can do more than 1.2ghz.

Anyone could do it easily, but I"ll see what I can do. I've gotten ahold of roto's initrd, I just need to grab the source from Samsung. I don't get home until very late in the evening so I can't promise that someone won't beat me to it!
