[Galaxy Note GT-N7000 Android Development] forest1971:
*** THIS KERNEL ONLY SUPPORTS SAMSUNG TW JB 4.1.2 ROMs (STOCK and CUSTOM). DOES NOT WORK IN CM or AOSP!!! ***

*** The Kernel is Safe (MMC_CAP_ERASE disabled) and the included PhilZ Recovery uses delete recursive and avoids brickbug ***

*** Stiil, I take no responsibility if the provided KERNELs causes any problem to your phone, you are warned! ***

Hello Friends,

I am no developer, just an Android lover. I share with you my first custom kernel for Note N7000 JB building from sources. It was made mainly for my hobby and my own needs, but hopefully can be useful to other members.

Forest-HelloWorld-Make-II kernel

As the name suggested, it is essentially a continuity of the C.O.H HelloWorld kernel.

FEATURES:

Features added by me:

- Implement r3p1 GPU driver to JB4.1.2 (from V2.0.0 (Credits and thanks to [MENTION=5145944]GeeckoDev[/MENTION] for this excellent work)

- OC OLED panel refresh rate to 60 (from V1.9.1)

- Remake GPU to 4 steps (V_1.9.0) (Very capable for gaming why maintain good battery life)

- Compile using Linaro toolchain 4.7.4.(12.2013) (V1.9.0) (it feels silky smooth)

- Update recovery to PhilZ Touch 5! You have a more beautiful and intuitive GUI. (from V1.8.2)

- Use LZMA compression (from V1.8.2).

- BLN support (only for V1.7.3)

- Enable OC CPU to 1600 (from V1.6.4 for OC CPU versions)

- Exfat native support (Now you can enjoy unlimited file size and fast speed on ext-sdcard)

- Kernel linux version 3.0.31, build using Ubuntu 13.10

- Toolchains: CodeSourcery G++

- Some optimization of the config file

- Su binary is updated to the latest version.

- Made three versions: 1) With OC of both CPU and GPU 2) With stock CPU and OC GPU and 3) With stock CPU and GPU.

Features benefited from C.O.H kernel:

- CPU Hotplug support from Speedmod kernel (only 1 core when not in load, battery friendly)

- Disabled logcat and dmesg and unnecessary Samsung debugging.

- UV capability.

- Increased Touchscreen sensitivity even when charging (Best touch response to date in Note).

- FSYNC Control 1 (from Ezekeel's GLaDOS kernel for Nexus).

- Tweak GPU in GPU OC version: 133, 267, 400 MHz (3 steps),

- Many cpu governors and schedullers: Defaults are Hyper-Row now (You can also tried noop-pegasusq as recommended by C.O.H)

- Fix for wifi drain on standby (disabled all multicast).

- Speedmod K5-3 fixes included

- Other features are the same as in c.o.h’s HelloWorld Kernel.

-------------------------------

HOW TO ENABLE LOGCAT (Only for V1.6.4 and lower!) .Credits to [MENTION=336619]hardcore[/MENTION]:

If you want to re-enable logcat for whatever reason, do this:

adb shell

su

mount -o remount,rw /system

echo ANDROIDLOGGER >> /system/etc/tweaks.conf

mount -o remount,ro /system

exit

Reboot android system. Then can take logcat as you wish!

--------------------------------

The kernel is very smooth, stable and battery friendly.

CHANGELOGS

:

HelloWorld-Make-II-V201-P:.

- OC-CPU

- Stock GPU

- Compile using uber toolchain 4.7

Excellent speed and good battery life. This is my current most favorite one.

HelloWorld-Make-II-V2.0.1:.

- Stock GPU and CPU.

- Compile using uber toolchain 4.7

Excellent speed and good battery life. This is one of my favorites.

- Change logs of other versions: see links in download section!

HelloWorld-Make-II-V1.9.0:.

- Remake GPU steps

+ Forest_HelloWorld-Make-II_V1.9.0_AM1 which is more agressive with GPU steps: 133-267-333-400

+ Forest_HelloWorld-Make-II_V1.9.0_GL2 which is more gracious, gentle with GPU steps: 133-200-267-333

- Disable UV interface.

HelloWorld-Make-II-V1.8.2:.

- Update Philz recovery to PhilZ Touch 5.

- Putting back logger module with option to enable it (for those who want to get logcat)

- Use LZMA compression

- Set default Governor to Pegasusq

- Update su and SuperUser to V1.94

- BLN dropped!

Bugs:

- The OC-CPU version has stock video bug the same as V1.6.4. Use MX video play instead!

- Recovery only accept to format internal and external sdcard using default format.

HelloWorld-Make-II-V1.7.3:.

- BLN support added.

HelloWorld-Make-II-V1.6.4:.

- OC CPU to 1600 (you can enable it using Nofrills or SetCPU...)

- UV 25mv for each steps, for balance performance and battery life.

- Include VR I/O scheduler, leave out Deadline

- Tweak thermal threshold (first level from 64 to 70, second level threshold keep the same).

Significant improvement for heavy games: I can play my favorite Let's Golf 3 super smooth now.

Bugs: stock video only play from gallery. Use MX video which is much better, btw.

HelloWorld-Make-II-V1.5.5:.

- Leave out some Governors, keep only 5: Hyper, Performance, Ondemand, Pegasusq, and SmartassV2.

- Leave out I/O Schedulers, keep only 5: Row, Sio, Noop, Cfq and Deadline.

- Padding zImage to the full size of the Kernel partition, 838808 bytes (Thanks to the trick by Chenglu and PhilZ!) this should help make the flash of kernel always clean.

- other minor tweaks

The new version is leaner, lighter. Should help improve performance and battery life!

For those who is on V1.4.5 it is recommended that you move to V1.5.5
