I'm seeing kernel panics in 1.1-stable, apparently when it's trying to go to deep sleep. Reverted back to 1.1-test, they are gone.

My Synapse tweaks:
A57 min freq: 500MHz
A53 min freq: 200MHz
A53 max freq: 1600MHz
HMP upthreshold: 1000 (maxed out)
GPU min freq: 100MHz
LED fading enabled with default settings
Some charge current tweaks

(As you can see, I'm trying to use the A53s as much as possible, to save power.)

Other changes: rooted, Xposed 75.2 (Wanam), LiveBoot, logcat reenabled using init script. Base ROM is COI4 stock.

Also, Synapse is unable to back up profiles, complaining about missing sysfs files.

Sent from my SM-N910C using XDA Free mobile app

1st of all what do you know about sysfs .?

2nd All settings mentioned are normal else then HMP ( That will not save anything and make your devise Unstable)

And yes there is minor glitch in Snaypse while backup profiles and thats not due to error its because of TCP setting which i implemented temporarily not included in backup .json script but It do not effect Backup/Restore at all ( and will be fixed in next update)

All panics logs you seeking is only due to wrong settings of yours rest of it nothing changed which cause deep sleep issue and yes that includes "Snaypse Live" logs offcource and nothing else to worry about .

Wooohoo!! Cant wait for this bitchiest ***** kernel to be updated!! Best kernel for 5.1.1!! No lags, good multitasking, no heating issues(even with 3d games), and most of all, best in batt. Life!! A blessing indeed for n910c users! XD Cheers @djmax81

Tip of the day : If users are using Note 5 ported rom and suemax Lite v1.1 kernel then i'll recommend to use STOCK (Governor) instead of Interactive (Governor) due to DVFS issue in Note 5 Firmware.

And kindly report.!!!!

What is STOCK? I only see 4: ondemand, userspace, interactive, and performance.

Edit: Found it. You're talking about GPU, right?

    Suemax-kernel for N910C/H and N910U

    CAUTION: I'm Not Responsible for any kind of Damage to your devise or Hard or Soft brick and even any damaged MicroSD-cards And now your devise warranty is Void and knox trip 0x1.





    Note Read Carefully Before Flashing my kernel :

    1) Keep the thread clean and try to research before e.g Google or wiki Before posting any further queries.

    2) As mentioned Over-Clocking and Under-Clocking CPU or GPU is Not really healthy for Devise Hardware,So keep in mind its
    Only an Option i'm providing due to its Got some limitations and might Damage soc in Extreme
    .


    3) Under-Volting or Over-Volting CPU or Gpu to Extreme is not Helthy either And on Exynos 5433 soc it waries on scale
    ASV-Group 0 to 15 (The higher the ASV, the higher frequencies your device can run and lower voltages).



    4) And Ofcourse Need not to ask best settings (This term does not exist) for your devise e.g Undervolting etc And read
    point 3 again . FYI : All users are different and So is devise Soc and there Usage + Usability of each User.



    5) About Random-reboots are often Happens due to Unstable user Settings .So think twise before to apply any setting in
    Snaypse app e.g CPU ,GPU or IO requires resrating Snaypse App or Even reqires a Rebooting devise to make apply proper
    Setting like Under-Volting or IO scheduler.


    6) No Asking ETAs and Special-demands .

    7) Everything is detailed and explained in Synapse app for Most Users and All settings Values are Stock On first Boot.

    8) Use Only SYNAPSE app to Control Kernel.


    Kernel log :


    1) CPU Clock A57 aka Big-cores : 500mhz to 2100mhz limitations (700mhz- 1900mhz set to stock default)

    2) CPU CLOCKS A53 aka Small-cores : 200mhz to 1600mhz limitations (400mhz- 1300mhz set to stock default)

    3) CPU GOVs :

    a) INTERACTIVE (set as Default)

    b) ONDEMAND ( Optional and tweaked for extra powersaving + performance)



    4) GPU CLOCK :

    a) limitations : 100mhz to 730mhz (160mhz - 600mhz set to stock default)

    5) GPU GOV :

    a) INTERECTIVE (set as Default)

    b) DEFAULT (stock)

    c) BOOSTER

    d) STATIC


    6) Mali POWER POLICY CONTROL

    a) Coarse_demand

    b) Demand

    c) Always_On




    7) IO Schedulers :

    a) CFQ (set as Default)

    b) NOOP (Optimized )

    c) DEADLINE (Optimized for better performance + SSD)

    d) ROW

    e) BFQ (Added latest version-7r7 by @paolo Valente)

    f) FIOPS

    Note : Read This post for more Information about IO and CPU govornors http://forum.xda-developers.com/showthread.php?t=1950084



    8) NTFS (Enabled + 3rd party app control)

    9) DE-knoxed (ramdisk + Kernel)

    10) SELUNIX : permissive (Samsung Hard enforcing)
