Default [KERNEL][TW] Note2Core v2.10- Standard, OC, Extreme,AsylumCore

[KERNEL][TW] Note2Core v1.06 -Standard, OC, Extreme,AsylumCore
Note2Core Kernel for Galaxy Note II N7100 / N7105 (LTE)


I am posting this here because it works on our LTE notes, since they all use a Qualcomm modem. I am running on my TMO T889 note with no issues. All credit goes to g.lewarne,antiochasylum - I am just posting here to so he doesn't have to maintain 2 threads. See their original post

About this kernel
This kernel is built from pure Samsung GT-N7100 source, with modifications and tweaks to provide the best user experience in reliability, performance and stability. Built upon my experience firstly with NoteCore and then HydraCore for the original Note, as many of you know, I strive for the best

There are 3 versions of each kernel, for the International LTE model GT-N7105.

This kernel has all debuging removed - logcat, android log, kernel log, schedular log, etc etc all disabled. This is for performance reasons, so if you are a developer this kernel is probably not for you

For the moment, exFAT formatted SDCards are not supported


Kernel Versions
There are three variants of the kernel for each device

STANDARD (STD) - 1.6ghz FSync() enabled
OVERCLOCK (OC) - 1.8ghz FSync() enabled
EXTREME (EX) - 1.8ghz FSync() disabled

The standard version, has no modifications to the processor clocks or voltages and can be considered a direct replacement for the stock kernel, and with FSync() enabled is completely stable

The OC kernel automatically scales up to 1.8ghz, with the proven voltages and stability from the perseus kernel (the same frequency table is used), and with FSync() enabled is completely stable

The EX kernel also scales to 1.8ghz, and has FSync() disabled. It offers by far the best possible performance. In rare circumstances you must be aware that this can lead to data corruption and the need to wipe / reflash a rom back to the phone. 99% of people will have no issues with this, as it has been extensively tested and proven on my previous kernel, but the risk is there. Dont go moaning to me if you lose your data and haven't got a nandroid backup!



Kernel Features
- Built from official GT-N7100 sources
- 1.6 / 1.8ghz auto scaling
- Optimised VM memory settings, and global readahead
- Auto-rooting of any rom when flashed, even stock
- init.d script support
- CPU Voltage support through 3rd party apps
- Modified GPU DVFS utilisation steps for maximum GPU performance, far better than stock (this is NOT overclocking!)
- No logging / debugging of any kind for higher performance
- Decreased CPU frequency transition latency
- CRC32 slicing-by-8 algorithm
- SLUB allocator
- PEGASUSQ governor (default, others available)
- NOOP schedular, (default, others available)
- +50mb more free ram compared to all other kernels
- lots of other minor tweaks and changes
- ODIN TAR and CWM ZIPS available for all versions
- TouchWiz roms only

- other optimizations

Changelog
V2.10

- All rotation issues in 4.1.2 fixed
- GPU steps reworked for better speed and responsiveness
- Built with linaro 12.11 GCC toolchain, with -O3 optimisation level
- lots of other internal changes

v1.06
-Fixed Triangle Away
- Maybe fixed rotation / sensor issues on some of the new 4.1.2 roms

1.05
- Fixed all voltage setting and reporting problems (you may need to clear app data in your chosen voltage app)
- Swapped to arm-eabi- 4.4.3 google toolchain rather than arm-linux-androideabi- 4.4.3
- Some minor bigfixes
- Decreased bus frequency increase threshold

v1.02
- Fixed video recording
- Added custom boot animation support, to use place desired boot animation in /system/media under *bootanimation.zip*

v1.01
- Fixed video playback for some users.

v1.00
- Initial release


GPL and Source
I dont use GitHub, so I make my entire kernel source, kitchen, build scripts, ramdisks and build tools available in one complete tarball. Also included in the TAR is a standard .patch which anyone can use to apply my changes against their own source tree. Almost everything you need to make your own version of a Note2Core kernel is included in the download - the only exceptions are the required linux packages.

You can download the latest source here - http://www.hecubus.com/filelist.php?...2core%2Fsource

Make sure download and flash N7015 kennel only and For the moment, exFAT formatted SDCards are not supported.
Thank Gavin and Antiochasylum .All credit go to them

For anyone who might not know, HydraCore for the Original Note was by far the fastest & smoothest kernel available. It also gave enhanced battery life compared to stock. I know that sounds improbable to get higher performance even at a higher clock and with better battery life, but it's true!

Unfortunately, I have not had much time to research the implications of swapping kernels (especially since there seems to be added modification detections in place compared to the Note 1) on this phone since I've only had it for a few days now, but when I do this will be my first attempt. Currently I'm just rooted w/o custom recovery but I'm dying to further enhance my phone.

Kennel had both version : Tar file for Odin and CWM for Custom Recovery.

I won't be able to make the jump because I'm leaving for vacation tomorrow and really don't want to kill my phone before hand, but when I get back I'm taking the dive.

A couple questions, if I'm rooted but without custom recovery can I just use mobile Odin or Pc Odin to flash the kernel? Will this give me a custom recovery? Also by doing this will it increase my flash counter?

I care lol! I still get some occasional choppiness while using ADW. Does your note run smoother now? Also does it improve the wake up delay/lag?

DONATE TO ME
I don't know anything about Kernels but I always love trying new stuff. I was just wanting to see if anyone could comment on what the author of the perseus kernel said about using this kernel on one of the American variants of the Galaxy Note 2? He said,
"The author completely disregards that the US versions have some hardware changes to them and using the 7105 kernel image on this device can be potentially dangerous as the GPIO pins between the US versions and the international version are different and things like battery charging can break. There are several power and charging differences between the two. It's lucky that this is only the AT&T version as on other carriers it would also break sound and volume. Use at your own choice but it's not something to be recommended."
I'm not trying to stir things up I just want to make sure it's safe to use this long term and I don't know enough about Kernels to know the difference. Thanks.
