[Galaxy Note 8.0 (Tablet) Android Development] civato:
Info & Thanks

What you need to know before you use this kernel.

This kernel got Selinux

Permissive state

as it supports more apps like TiTaniumbackup.

Reverting back to a Selinux enforced Kernel (stock) is no longer a problem from Rev3.0 and up.

You can set Selinux Status with the included Synapse app

You want to know why this kernel comes with Selinux included, google for Selinux and search your answers.

AllCast mirror will not work as this is a Samsung thing and not opensource.

If this is a problem for you, don't use this kernel.

DISCONTINUED , A NEW THREAD WILL BE OPENED FOR THE NEW KERNEL SUPPORTING ONLY THE KITKAT BOOTLOADER.

NO JELLYBEAN BOOLTOADER SUPPORT, IT IS TIME TO MOVE FORWARD.

INSTALLATION

Take a full nandroid backup.

NO NEED TO BE ON ANY KITKAT BOOTLOADER (your wifi will work with this kernel)

YOU NEED TO BE ON A KITKAT TOUCHWIZ ROM.

Install with cwm

Thanks:

sidmoraes for pointing me to other kernel source that I could use as base, still had to change some stuff but this is better then waiting for samsung to release there source, if they ever will. (Finally Samsung released source)

Andreilux - Faux123 - Yank555.lu for kernel work

ZaneZam for the zzmoove governor

​

​

This kernel comes with the policy: IT IS AS IT IS.​

Use at your own risk

Take a Nandroid backup of your system and of your boot.img

You need to be on custom cwm to install this

ONLY FOR SAMSUNG TOUCHWIZ BASED KITKAT ROMS​

Benchmark scores:

Stock Normal Note8.0 Antutu Ranking. 17708 points

My Antutu = 23486 points

Stock Quadrant ranking = 6613 points

My Quadrant = 13685 points

CivZ-SphereKat-REV5.4-GT-N5110-5100/5120 And older versions.

Never install a kernel that is not for your device, it will cause a hard brick.

Stock kernels can be found in the SphereKat folder of your device

The only good app to control this Kernel is the included SYNAPSE app​

Example of what synapse looks like,THIS IS JUST A EXAMPLE.

SphereEngine KERNEL Features

If you

change nothing

these are the following Features/optimisations you get compared to Stock:

SELINUX protection included but set at Permissive = No problems wit apps like Paragon and Titainium.

SELinux control with Synapse

S-Pen Alignment fixed

Default Speeds 200MHz-1600MHz

Activating Saving power will result into 200MHz-1100MHz.

GPU Overclocking thanks ZaneZam / DerTeufel / AndreiLux

GPU settings are:

Step0 54MHz = new Idle step = when in browser mode and no gaming this low GPU speed will help save power

Step1 266MHz

Step2 350MHz

Step3 533MHz = new speed foe step3 for better performance in drawing

Step4 700MHz = New OC speed for the better gaming performance

GPU settings are not editable and hard set in the kernel

Init.d support

ARCH-Power enabled

DynamicFSYNC = Use Terminal command or Trickster Mod app. = enabled by default.

Memory Leak fixed

mmc cap erase disabled ( just as a precaution )

[*]IKCONFIG_PROC support

Driver support included in kernel:

NTFS_RW / FAT / FAT32 / EXFAT support

3Gusb Support (ppp widget)

CIFS / UFS / ISO9660 / UDF_FS / HF / HF_PLUS

Realtek RTL8192CU/RTL8188CU USB Wireless Network Adapter support

Ralink driver support : Ralink rt2500 (USB) / Ralink rt2501/rt73 (USB) / Ralink rt27xx/rt28xx/rt30xx(USB)/rt2800usb - Include support for rt33xx , rt35xx , rt53xx

Extra Drivers: MAC80211 / RTL8187 / EEPROM_93cx6 Support

Boeflla 1.6.0 Sound engine support

OTG Audio dock , Car dock support

[*]SideSync support

[*]Dynamic Samsung Hotplugging

Note on CIFS:

Example on what you enter, but your IP and share, if that wasn't clear. The option section is very important

Note on NTFS

You need to use Paragon!

You need to set your mount point yourself.

Example and recommended is:

/mnt/extSdCard/paragon

Advanced users support

OC & UV support for CPU

Max CPU speed is 1920MHz

Min CPU speed is 100MHz

Governors: Adaptive, Pegasusq (recommended), Performance, Ondemand, Interactive.

Schedulers: cfq, Noop, Deadline, Row, Sio, VR

Extra TCP wifi connection added: Westood, reno, htcp, vegas, veno.

Changelog:

07/Jun/2014 First Public release Rev2.0

08/Jun/2014 First Public release Rev2.1

[*]GPU step 5 included, now max it will go to 533MHz

[*]Auobrightness sensor fixes part2

[*]CPU sloop adjusted

[*]zzmoove profile nr8.

09/Jun/2014 First Public release Rev2.2

[*]Memory Leak fix cpu stats

[*]Memory Leak fix Kernel Ext4 & Power

[*]zzmoove profile nr6.

I recommend not to use Interactive and Powersave governor as they are buggy.

09/Jun/2014 First Public release Rev3.0

[*]Selinux included in the kernel as more security is better. This is the reason why I bumded to Rev3.0 to make a clear difference.

This kernel got Selinux

Permissive state

as it supports more apps like TiTaniumbackup.

Reverting back to a Selinux enforced Kernel (stock) is no longer a problem from Rev3.0 and up.

You can set Selinux Status with terminal command to ENFORCED with "setenforce 1". Or use a init.d script to have it on reboot also on ENFORCED.

You want to know why this kernel comes with Selinux included, google for Selinux and search your answers.

[*]Governors , powersave, userspace = Disabled as they are useless and buggy.

10/Jun/2014 Rev3.1 Released:

Ramdisk changes

Interactive set on all parameters as startup and default governor, this to prevent lockup of cores on boot.

Synapse SELinux status oprion, change to ENFORCED & PERMISSIVE , default is permissive

Small tweaks in kernel boot_up custom script.

12/Jun/2014 Rev3.2 Released:
