Ramdisk:
-use HC 3.1 supplied ramdisk
-ro.secure=0 (adb root shell)
-remove setting min/max/governor after boot (moved to the kernel).

Note:
-If you want to bench, it is advised that you set min/max to the same number.
-For Custom roms: Be aware, I’ve put the wifi module right in the ramdisk (which is where it is on 10.1 stock). Please move over the modules folder in /system/lib prior to flashing, if this applies to you. I will most likely flash this in myself and yank it from the ramdisk moving forward.
-This will not work on the ‘v’.

Known Issues:
Issues from Stock to be resolved:
-Slight delay on wakeup (introduced in HC 3.1) when not plugged in, and/or having to press power up to two times to wakeup (rare (if it is busy doing something)).

Things to do:
Implement pulling/constructing the ramdisk while flashing.
Undervolt low/mid ranges
Implement UMS

Installation Instructions:

Flash in recovery.

Download the latest SetCPU from this thread:
http://forum.xda-developers.com/showthread.php?t=505419

Launch it, accept root allowance and select autodetect.
ondemand will be the default governor

To install kernel modules:
Use Winrar (windows) or tar with the z option and unpack lib-2636.4.tar.gz
Push any module you desire to /data/local/modules (this is created by the update.zip)
Then, insmod it (you can do this via adb, in a gscript, or on the device in terminal.

If you are using any of the external modules, please download them fresh and re-push them in to place.

Note:
-If you are on the stock rom/stock’ish rom (froyo), set your wifi to never sleep.
-At sleep, if you have the USB cable plugged in and find that you cannot wake the device, unplug, and press power to wake (this is more prevalent on the stock/stock’ish rom).

Known Issues:
-warning from manage irq and nvec release function
-When waking up from standby/sleep, the clock in the status bar will change when RTC changes in the next minute (stock rom).
-If your BT Audio device does not work with the the stack that comes within your ROM, no audio will be sent to your device, and once you disconnect, you will need to plug in a 3.5mm jack and unplug to get audio back.
**Devices that don’t work: Jabbra.
**Devices that do work: Parrot audio, Jawbone, Nokia BH-905.

Things to do:
-clean up the barrage of warnings from TapnTap/Viewsonic’s patch

Instructions:
Flash the .zip through recovery

To use one of the kernel modules:
Pull the one you want from lib-2632.42.tar.gz (winrar can open this),
adb remount
adb push MODULE.ko /system/lib/modules/2.6.32.42-cyanogenmod/
adb shell chmod 644 /system/lib/modules/2.6.32.42-cyanogenmod/MODULE.ko
adb shell insmod /system/lib/modules/2.6.32.42-cyanogenmod/MODULE.ko

Note:
You can download gscript lite from the Market, and put the insmod line in there, and tap when you want to insert it and use its functionality.

Overclocking-
How-To:
-Install the latest SetCPU (2.1.3 is current) from the market and/or XDA (http://forum.xda-developers.com/showthread.php?t=505419)
-Select auto
-If using CM7, then you can use the included CPU Settings within CyanogenMod Settings.

Note:
If you were using SetCPU prior, with ‘custom’ and this kernel set, please go to device selection and select auto. Please delete the custom setcpu file on your filesystem:

adb shell rm /data/local/setcpu

Note2:
Be aware, that if you leave it pinned to max, hammering it, it will get warm/warmer then your used to at 1GHZ, pinned.
It is advised not to select any of the 2 governor’s listed (but, at the very least, not performance).
It is advised to keep your min value at 216.

-initial release (7/2/11)
-use GT-P7510 source from opensource.samsung.com and supplied defconfig, as a base
-merged up to kernel.org’s, 2.6.36.4
-oc to 1.4GHZ @ 1.225mv
-increase voltages to system/core
-similar optimisations as gtab-2632 (-O2, cortex/vfp/fp optimisations via CodeSourcery 2009-q1)
-merged in various changes from gtab-2632, vision-2635, AOSP, kernel.org and nv-tegra.nvidia.com
-Autogroup (session)
-PS3/XBOX360(JOYSTICK),NTFS,CIFS,AUFS, mouse
-use koush’s anykernel in its partial form.

Ramdisk:
-use HC 3.1 supplied ramdisk
-ro.secure=0 (adb root shell)
-remove setting min/max/governor after boot (moved to the kernel).

Note:
-If you want to bench, it is advised that you set min/max to the same number.
-For Custom roms: Be aware, I’ve put the wifi module right in the ramdisk (which is where it is on 10.1 stock). Please move over the modules folder in /system/lib prior to flashing, if this applies to you. I will most likely flash this in myself and yank it from the ramdisk moving forward.

[Preview] – 2.6.36.4 – OC-VFP_FP 1.4GHZ – Galaxy Tab 10.1

This is a preview of what I have been working on. There is more to do, so am making this a preview until I have some other things smoothened out and other things honed down.

I will post an extensive changelog and add to RM after the upload to github completes.

-use GT-P7510 source from opensource.samsung.com and supplied defconfig, as a base
-merged up to kernel.org’s, 2.6.36.4
-oc to 1.4GHZ @ 1.200
-same optimisations as gtab-2632 (-O1, cortex/vfp/fp optimisations via CodeSourcery 2009-q1)
-merged in various changes from gtab-2632, vision-2635, AOSP and kernel.org
-Autogroup (session), various ERRATAS, BFQ I/O scheduler

Flash in recovery.
Download the latest SetCPU:
[url]http://forum.xda-developers.com/attachment.php?attachmentid=631523&d=1308620121[/url]
Launch it, accept root allowance and select autodetect.
Select ondemand for governor.

Note:
If you want to bench, it is advised that you set min/max to the same number.

Please let me know if there are any issues. Please report all issues with a log in hand (/proc/last_kmsg (if there is a reboot) and/or dmesg).

Known Issue:
-The governor may reset back to conservative (default), when using ondemand, after wakeup. This will be investigated.

User Report:
-Fired up File Expert, turned on FTPd, began transferring a couple of roms over to it (legally owned, of course). HARD LOCK, REBOOT.

Installation Instructions:
adb push su_busybox_misc-sam_tab_10.1-061611.zip /sdcard/
adb reboot recovery
volume down to apply update from /sdcard
select .zip
hit power to select
scroll down to apply, and apply.
after flash, reboot

Note:
For Windows it is reccomended you use adb putty, if you are going to use htop/vim/vi/bash,etc.:
Make sure adb is running. If not, please launch it by typing: adb devices
launch putty.exe
Select Adb
Under Host Name type in: transport-usb
Highlight Default Settings and click save
Select Open.

Note2:
If you should ever wipe, please do this:
create a /data/tmp as shell:shell, 774
create a /data/.vimrc as root:shell, 444, with the contents: set directory=~/tmp
This is so VIM will have a temporary space for recovery.
