Default [KERNEL][TW] Note2Core v2.10 - Standard, OC, Extreme; AsylumCore 2.11

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 I on my AT&T note with no issues. All credit goes to g.lewarne - I am just posting here to so he doesn't have to maintain 2 threads. See his original post here

For the moment, exFAT formatted SD cards are NOT supported.

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 4 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



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
ASYLUM (AS) - 1.920ghz 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!

The AS kernel is meant for the crazy ones. People who come from an asylum, those from the Note 1 know I am crazy, so this was meant for them. If there is a demand for the 7100 I will build that as well. I am not responsible if you are able to cook bacon on your device after running. It features up to a 1.920ghz over clock, and 640ghz on the GPU, it will go up, however for the moment we will run with 640. The phantom bug is that voltages cannot be set with SetCPU. Neither myself nor gavin know why. The code is spot on. So we don't get it. Lol. The source code is on github.com/glewarne



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



Download - Current Version v1.00

Hmm I flashed the OC version on my note 2 seems to be running great but the phone does not see my external sd card :/ just says external card removed safe to remove now even when trying to remount it, my card is formated to exFat not sure if that is the problem

Yes, exFAT is not supported, we just found out. A fix is coming soon. Also videos in games such as zombie wood don't play. Fixes coming soon.

Nice to see another kernel here.

Can you please update the OP with a link to the original n7100/n7105 kernel thread? (It might make it easier for users to pop over there and see current discussion, etc.)

Also, I'm kind of curious what kind of difference people have noticed by blocking the majority of kernel logging. In theory, it shouldn't make make a significant difference, but I never got around to testing it, so I'm not sure how well the theory applies. (kernel logs aren't backed by persistent storage, so there's no real I/O overhead to it.)

Take care
Gary

So I checked the extfat on extreme and I have access to all files. Also checked the storage under settings and everything looks to be mounted.

sent using gNote II.
