[KERNEL] [SM-T800 WIFI & T805 LTE] [30 Sept] SkyHigh TW Kernel [R3_v1.8] [Synapse ++]

10.5" SM-T800 WIFI & T805 LTE TW Exynos 5420 supported in thread only !!

I don't have time to build for any more devices I can't personally test & debug - sorry.


Let get it straight, I am not a real Developer, but I am UpInTheAir, part time kernel hack of SM-T700/705, SM-N9005 LTE, SGT 7.7 JB & ICS Kernels. I now share with you my Exynos5 TW SM-T800 WIFI & SM-T805 LTE kernels compiled from official Samsung sources.


* I don't pretend to know everything, so if you can be constructive and help out this project, please do so. You will find allot of answers by searching gitHub, XDA and SEARCH Just like I do ......


>> SCREENSHOTS << from T705 v0.5 : might not be always up-to-date !


FEATURES

Based on official Samsung source: T700OPU1ANG2

ramdisk source: T800ZCU1ANG2 & T805ZHU1ANG2

Built with Stock ARM Toolchain 4.7

Compiled with KERNEL_MODE_NEON & -mfpu=neon-vfpv4 & hard float

KNOX WARRANTY VOID: 1

SELinux PERMISSIVE

adb insecure

ROM Knox removal via updater-script on flash

init.d script support (drop in script & set permissions to 755 or 777 and reboot)

Question HELP & FAQ
HELP & FAQ


"SYNAPSE BOOT CANCELLED"

 
  1. Wait for the kernel to stabilize and device to cool
  2. Open synapse app
  3. Synapse app menu > select all globally > undo > apply ✔
  4. Re-boot
  5. If still issues > try again after #1
  6. Still issues > Manually set config after boot (open synapse app > syanapse app menu > settings > disable apply on boot)


ISSUES

 
  1. Uninstall any CPU control apps, tweaks and scripts etc.
  2. Install Wanam DVFS disabler for greater kernel control
  3. Flash kernel
  4. Boot and allow things to stabilize
  5. Open Synapse & tap :
    "understood" message about unstable boot
    "select all globally"
    "undo" button
    "apply" ✔
  6. Reboot and ensure "synapse boot completed" toast message
  7. You should be good to go


BOOT-LOOP

 
  1. Power off & let device cool
  2. Wipe cache & dalvik-cache in recovery (if custom recovery)
  3. Re-flash kernel
  4. Re-boot
  5. Let things stabilize and cool before touching anything


BETTER BATTERY LIFE

 
  1. There are no best settings. User "HABIT" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
  2. This kernel is built to be balanced with a good mix of battery whilst keeping performance
  • Decrease screen brightness
  • Use dark wallpapers and app themes
  • Check your wakelocks with better battery stats app & use Greenify app to stop unwanted apps self starting and running in the background
  • Suggest:
    CPU governor = ondemand (tweaked for power efficient workqueues)
    CPU 200-1900 MHz -25 mV
    GPU 100-480 MHz -50 mV (100 MHz may induce some GUI sluggishness)
    PowerSuspend Driver = Enable
    Dynamic FSync = Enable
    Dirty Page Writeback = Enable
    CPU Multicore Power Saving = (2) Agressive


BETTER PERFORMANCE

 



HOW TO BACKUP YOUR STOCK KERNEL BEFORE FLASHING SkyHigh KERNEL

 
  • Boot into TWRP Recovery
  • Select Backup
  • Select "[X] Boot" only (boot.img/kernel)
  • Select Storage > Micro SD (if external sdcard installed) > OK
  • Swipe to backup



CAN I USE OTHER KERNEL CONTROL APPS

 
  • No, many features and options won't be available. Remove all other control apps to avoid conflicts !
  • Synapse is the recommended and has everything you need ;)


HOW TO MONITOR LIVE CPU & GPU VALUES

 
  • CPU load & freq - available RAM - GPU freq - CPU temp - most resource intensive process
  • [APP][2.1+] Cool Tool
  • Download my personal cooltool_presets > unzip & copy folder to INTERNAL sdcard. If you have cool tool app already running, you must disable > overwrite existing folder > enable


LITTLE CORE CPU FREQUENCY

 
  • Real frequency is apparently double that reported by other apps
  • Example: min 200 MHz (real) in Synapse is reported as 100 MHz in SetCPU


RANDOM REBOOT

 
  1. Don't UV or UC CPU or GPU
  2. Use SkyHigh defaults


DOWNLOAD LINK NOT WORKING

 
  1. I want to keep this project all in one place (Thanks to XDA) - ☆☆ NO MIRRORS ☆☆
  2. Please try again in a few minutes


POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE

 
  1. Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
  2. HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE


DO NOT KILL PROCESSES

 
  1. This feature allows the user to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
  2. When a the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
  3. If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
  4. You can find the [SkyHigh/Synapse] folder on your internal sdcard and add one process name per line. Lists updated on reboot.
  5. Max 25 processes
  6. Example only:
    Code:
    com.ea.games_r3_row
    com.quoord.tapatalkxda.pre.activity


DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS

 
* [Christopher83]

Quote:

This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.

Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature,
set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page
writebacks when the system is active (screen on)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)

This feature is in part inspired on Francisco Franco's patch:
https://github.com/franciscofranco/m...18e7f258a22947



BACKUP & RESTORE

 
  1. If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
  2. Reboot after applying your new settings
  3. Read "ISSUES" & "SYNAPSE BOOT CANCELLED" above


TCP/IP NETWORK SECURITY

 

* Thanks to zeppelinrox & V6SuperCharger
  1. Hardening the TCP/IP stack to SYN attack
  2. Bump up tw_buckets in case we get DoS'd
  3. Ignore pings
  4. Don't cache connection metrics from previous connection
  5. Don't pass traffic between networks or act as a router
  6. Enable spoofing protection (turn on reverse packet filtering)
  7. Don't accept source routing
  8. Don't accept redirects
- Further reading:
http://www.cyberciti.biz/faq/linux-k...rity-hardening
http://www.symantec.com/connect/arti...ck-syn-attacks


SEGMENTATION FAULT

 
  1. I don't believe it's kernel related, but rather busybox
  2. Try uninstall your ROM busybox with this app. https://play.google.com/store/apps/d...ricson.busybox and reboot.
  3. Re-flash kernel
  4. Use the busybox that comes with the kernel located in /sbin
  5. Also try to update your SuperSu and su binary if it asks and reboot.

Location v0.9 release
Initial T805 LTE kernel v0.9 is officially released !!

Thanks to @619619 for the test

Please read carefully Posts #1-3 BEFORE doing anything. A lot of additional info can can found by searching


T800 WIFI Users:

I would like to build your kernel using T800ZCU1ANG2 ramdisk. I require the stock boot.img from this firmware. Without it, I won't biuld it.


Cheers,

UITA

v0.9 released for all models & re-uploaded T805 kernel
R3_v0.9 kernel is now released for supported 10.5" models

* re-uploaded T805 LTE kernel - fixed minor mistake

* T800 WIFI R3_v0.9 is untested. Please let me know how it goes........ I have added flashable Stock kernels in the Download section (if required).

For those on older ROM firmware, please upgrade or you might have issues that we can't reproduce. Otherwsie, stay with stock.

Ensure you flash the kernel for your device model !!

NOTE: commit credits are in source.

Further instructions in Synapse app & Posts #1-3


Enjoy

Cheers,

UITA

For those on older ROM firmware, please upgrade or you might have issues that we can't reproduce. Otherwsie, stay with stock.

Ensure you flash the kernel for your device model !!

Hi @UpInTheAir

I just had a small question you firmware is based on the ANG2. (CHN) right I had the ANFB. On a T800 wifi with stock rom I didn't like the other roms so far but I want to try your firmware not sure if flashing yours can break my tab . Do you had any subjections?
Thanks for sharing your work
