[Galaxy Note 8.0 (Tablet) Android Development] ykkfive:
ADVANCED FEATURES/SETTINGS/TUNNINGS:

CPU OC/UV (Over Clock/Under Voltage)

INFO:

CPU OC

control file: /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

default max cpu freq:

1600

oc max cpu freq:

1800

CPU UV

control file: /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

default voltage values for 1800mhz (left) to 200mhz (right):

1400 1400 1313 1263 1225 1175 1138 1100 1075 1050 1013 988 963 950 938 925 913

recommended under voltage values (tested, safe and stable):

1375 1350 1263 1213 1175 1125 1088 1050 1025 1000 963 938 913 900 888 875 863

FILES:

stock frequencies (no oc) with recommended uv

oc1800 with default voltage (no uv)

oc1800 with recommended uv

HOW-TO (for novice):

disable/remove any existing init scripts/tools/apps first or otherwise may cause conflict

pick one of the files above of your choice and put it under /system/init.d/ folder

settings will be applied at every boot (starting next boot)

the recommended uv values are based on the default value - 50

if you want to try another profile, remove the existing one first

in case your device becomes unstable, you can roll back to the original state by removing the file

you may try to alter the voltage values but at your own risks

it is suggested to modify the values one by one, and increase or decrease the value bit by bit

do not place more than one of the above profiles at the same time

there is no such things as best values since all devices are different in terms of hardware quality, usage, etc

Enabling/Disabling Logger Control

INFO:

a logger control is implemented in this kernel and by default it is disabled. follow the steps below for enabling/disabling the log

control file: /sys/kernel/logger_mode/logger_mode

HOW-TO:

to enable the logger control:

echo 1 > /sys/kernel/logger_mode/logger_mode

to disable the logger control:

echo 0 > /sys/kernel/logger_mode/logger_mode

the logger control will be enabled/disabled immediately upon changes

for enabling the log at boot time, put the enable log command in init script

MDNIE Hijacking Control (by Yank555)

INFO:

mdnie hijack control allows you to modify the color balance, black level, sharpness, etc, and to adjust saturation by changing the levels for each color like red in blue, red in green, yellow in red, white in blue

no screenshots can be provided as this is a post process for displaying on your screen only, screen captures are unable to read the new color settings and thus not affected

control file: /sys/class/mdnie/mdnie/hijack

original document by Yank555

FILES:

standard color profile

natural color profile

HOW-TO:

to enable the mdnie hijack control:

echo 1 > /sys/class/mdnie/mdnie/hijack

to disable the control, just remove the init script from init.d folder

download one of the profiles above and put it in the init.d folder

you can execue the script anytime via command line or by executing it with some file managers like root explorer

the color settings can be applied instantly, or you can setup your own profile and save it in an init script which will be applied every boot in this case

by default this control is disabled
