Wow, that's what I'm talking about. Thank you for this.

I think now people will start ask less and read more. :p

[MENTION=2562519]djmax81[/MENTION] I must to say that your Beta Kernel is wonderful.... I have no touch Kernel setting, and the phone work fast, and good battery. It's a great work. Thanks man. ?
[Galaxy Note 4 Android Development (Exynos)] darkbahamut:
To be honest, the undervolting isn't even the main problem. UV can cause crashes if it's too aggressive, but outside of that it's usual problem free.

It's people adjust frequencies that cause big problems. Changing them has adverse effects on how HMP migration works. It's not just as simple as moving a clock slider, you need to adjust HMP settings to account for the new cluster capacities, and this assume you aren't pushing the cluster into an inefficient position.

Underclocking the A53's is pointless. They use such a tiny amount of power at 400MHz that CPU power is only a tiny portion of the platform power in use. You save no power at all and will cause CPUFreq to oscillate clockspeeds which actually damages power consumption.

Underclocking the A57's is pointless. Threads migrate away from the big cluster once they become less demanding. The low clockspeeds largely go unused when the CPU is actually executing. All this does is ruin HMP down migrations as the cluster capacity changes for the down point, making the threads run on a worse perf/w curve.

I would actually call on kernel devs to remove the ability to 'underclock' the clusters. It serves no real world purpose at all and there isn't a single use case where running the clusters below the stock minimum speeds is actually any better for anything. It only serves to let people that don't fully understand HMP to basically ruin the whole system. It's literally a setting that can only cause harm.

So where did the full headphone audio controls go in synapse? Will they make a return? Did they ever work? Lol i kinda though it made a difference but i primarily use bt headphones. Wired headphones sounded better but im not sure if the settings took effect or not. 1.3 is a good update to 1.2 :)
[Galaxy Note 4 Android Development (Exynos)] white7561:
[MENTION=2562519]djmax81[/MENTION] can i req you to add f2fs support? Cuz it so freaking awesome. Its so speedy and it works on stock rom. (Tested bysomeone on korean note 4) thx anyway :)

I lost fast charging on dn5 after installing v1.3.

Could be a kernel issue?
[Galaxy Note 4 Android Development (Exynos)] white7561:
What do you mean u lost? I use dn5 but didnt try using fastcharge with timer. Will do later
[Galaxy Note 4 Android Development (Exynos)] voulgeor:
Lost means i connect the same charger i was connecting before but now after kernel flash no fast charging is taking place. I have enabled fast charging from dn5 control but nothing.
[Galaxy Note 4 Android Development (Exynos)] white7561:
The notification?
[Galaxy Note 4 Android Development (Exynos)] voulgeor:
No its not just the notification its the charging time.
[Galaxy Note 4 Android Development (Exynos)] ilker4fun:
This is bad news mate. I hope djmax81 fix it
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Its nothing to do with kernel just tick fast charge enable in dn5 settings app.
[Galaxy Note 4 Android Development (Exynos)] djmax81:
seems you two users are only one who having this Issue . An request research twice before posting any bug reports.

Note: For all suemax kernel users if you using any 3rd party Mods +script or Application other then not included my kernel . Need not to post over kernel topic thread and just an humble request take your queries about Custom rom or Mods thread as im not responsible for Troubleshooting.

[Galaxy Note 4 Android Development (Exynos)] ilker4fun:
You misunderstand me mate. I am not suffering this problem. I just said this is bad news the people who want to use dn5 note5 port rom.

PS:I tried to use dn5 rom with Sue max v3 and I didn't see any fast charge issue. My fast charge is working flawlessly.
[Galaxy Note 4 Android Development (Exynos)] djmax81:
No worries :) ! My friend my message was for all users in general to inform detailed Bug report . As i'm too on Dn5 v5 myself

Cheers
[Galaxy Note 4 Android Development (Exynos)] :
Thread cleaned.

Please take your disagreements to PM and keep them out of open forum.

Stay on topic.

Thank you.

Any details? :)
[Galaxy Note 4 Android Development (Exynos)] luetkmeyer:
Hi djmax81

I have downloaded 1.2 about 10 days ago for testing extended battery support. This works great... 95% accurancy (not kernel problem, thanks to much to incorporate the zip).

I have tested in many different charge and discharge situations (with USB current tester with current mA and acumulated mA). The mod works very well. The kernel is great! So:

Who have ZeroLemon Extended 10000 mA for Note 4 (see models in title) use Suemax-kernel-Lite-v1.2 and get relax: your battery will work amost 100% right.

And now? Can I pay one coffe to you djmax81?
[Galaxy Note 4 Android Development (Exynos)] JHColt:
The details are that you can't compare AnTuTu v6 score with v5 score. It is using a different base of points. ;)

http://www.antutu.com/en/view.shtml?id=8171
[Galaxy Note 4 Android Development (Exynos)] darkbahamut:
Not to mention AnTuTu isn't a good benchmark to even use in the first place. The scores it gives are just comical.

My note scores almost 85k for some bizarre reason.

Attached image below is the latest battery life i got from 1.3 beta on DN5 rom. Superb!

Just one bug I got, on suemax 1.2 my phone runs perfect without any issue. But in 1.3 beta I got weird reboot. My phone suddenly not responsive, the screen turns black, and i have to do 3 button restart to have it back on again. Fyi, I did not do any underclock or undervolt or install any other mod so it could be something else in the kernel. I didn't use other cpu governor except interactive. The reboot happens about once a day. And after reboot, my phone becomes really slow and needs about 3 minutes to be normal again.

Sorry i cannot provide you any logs. Hope this issue can be fixed in final release. I really love your kernel, gping back to v1.2 for now.
[Galaxy Note 4 Android Development (Exynos)] djmax81:
No worries !!! My friend battery stats seem pretty promising :) tho, i'll fixes for ondemand + conservative next stable relese .

Cheers

Cant be only with kernel only [emoji6] you did something. You made any other settings? You are clever on phones.

[Galaxy Note 4 Android Development (Exynos)] djmax81:
Nops stock settings just IO scheduler set to row = Read over Write

FYI : Nothing clever at all User must know how to setup basic settings and why one developer need to trick Users over own thread ? I simply do not UV , OC nor xposed for Note 5 roms (isn't it surprising) and mentioned many time earlier that all users are different + So are there usage and Device apps and settings .

Ok thanks

[Galaxy Note 4 Android Development (Exynos)] :
Thanks a whole bunch man...... I love you.

Also I was wondering if it would be safe to overclock the processor and gpu since I really want topnotch performance. I did it on v1.2 and it caused screen freeze sometimes
[Galaxy Note 4 Android Development (Exynos)] mirroalex:
I cant write anything on ntfs otg usb flash memory using v1.3, I was using v1.2 of kernel on erobot 11.1 and chainfire's stickmount program and everything was fine i could delete Or copy anything to my ntfs usb flash drive, but after updating to 1.3 i cant, anyway to solve this?
[Galaxy Note 4 Android Development (Exynos)] djmax81:
You need to use 3rd party app from play-store to mount Ntfs as writeable as android OS only mount and allow NTFS as readable (even tho kernel support ntfs)

INFO : And There is nothing changed about Ntfs or any File System in v 1.3 update kindly try fresh install kernel by deleting data + cache of Synapse app via system app settings (Apply fresh setting and do not restore any old Synapse profile)

Cheers

Cleared Cache of syanpse and restart and everything is back on track, thanks (using stickmount As always)
[Galaxy Note 4 Android Development (Exynos)] djmax81:
No worries !!! Kindly report or send catlog if you face any issue after fresh install tho, Good to have more App options always :p

Edited : Im glad that it working :) as there are few changes since v 1.2 to v1.3 so profile restore generally might causes issues .

[Galaxy Note 4 Android Development (Exynos)] majdmas:
I dont know if it is a newbie question or what, but the thing is:

I know this kernel is not rooted, so i have flashed a pre-rooted kernel (talexop kernel) to get root access, but my question is : if i flash suemax kernel will the root remain or i will loose root?

And if the latter is true and i will loose root, what is the solution to root my device? i have searched an looked around but could not find a clear way to root my device (N910C running 5.1.1 stock rom COJ5)
[Galaxy Note 4 Android Development (Exynos)] GialanG:
You can root with this kernel
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Nops its no auto in kernel root but you may flash update supersu v.2.62.zip
[Galaxy Note 4 Android Development (Exynos)] djmax81:

One quick question, and sorry if this has been already asked but do you need to wipe cache after installing your kernel if I'm coming from Perseus Kernel? Or can I just dirty flash it?

Thanks :)
[Galaxy Note 4 Android Development (Exynos)] djmax81:
All synapse based kernels same rule wipe data + cache and flash kernel.

[Galaxy Note 4 Android Development (Exynos)] Doomhamma:
Does that mean even when comming from an older version of your kernel to a newer one?
[Galaxy Note 4 Android Development (Exynos)] beefx:
waiting for new version to try :) :) :)

thanks djmax81
[Galaxy Note 4 Android Development (Exynos)] djmax81:

[MENTION=2562519]djmax81[/MENTION] hello bro. I am with erobot 11.2 and I have choice SpaceX Kernel because when I have choice Suemax beta, I have problem with restore Titanium data.

[Galaxy Note 4 Android Development (Exynos)] djmax81:
Just wipe cache + dv cache via custom recovery after flashing option of Aroma or just use latest 1.3 beta .zip and flash it via any custom recovery
[Galaxy Note 4 Android Development (Exynos)] travis82:
Cyanogenmod Kernel Version?
[Galaxy Note 4 Android Development (Exynos)] majdmas:
After flashing the kernel i have witnessed a drain in battery during the night.

I have fully charged the battery and have not used the phone over night, and after 8 hours there was a drop of 9%, and the device was wake for 1.30 hours during the 8 hours although i have not used the device at all

i have attached a snapshot of bbs where there r a few kernel waklocks that kept the phone awake like: "wlan_rx_wake" and "bcm4773_wake_lock".

i have also noticed that the cpu was working with the max freq during almost all of the wakeup time

has anyone noticed any same behavior? noting i use greenfiy and have disabled most of the bloatware through TB, and my wifi is always all the time with no 3g working
[Galaxy Note 4 Android Development (Exynos)] beefx:
Can i change touch boost level in this kernel?
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Use Wakelock Detector instead of this BBS and ofcource Nothing is alarming or wrong with bcm4773_wake_lock nor wlan_rx_wake .

Tip : The locks you mentioned are Gps and Wifi just turn off auto sync and its main issue of "play store service" drain :good:
[Galaxy Note 4 Android Development (Exynos)] kamisheikh:
would this work with 1.3 beta ??
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Yes ofcource .! And kindly read "SIXPERIENCEN4 V5"
[Galaxy Note 4 Android Development (Exynos)] efrainmartinez:
[MENTION=2562519]djmax81[/MENTION] is there some DVFS+GPU FIX for erobot 11.2 or is not necessary?
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Nops .! Its not compatible tho not very necessary after v1.3 as dvfs is already disabled by default.

[Galaxy Note 4 Android Development (Exynos)] djmax81:
This happens due to no Busybox !
[Galaxy Note 4 Android Development (Exynos)] djmax81:
For now Using stock settings will be just fine !!! :) And sooner you learn and get friendly to kernel Settings then start basic tweaking e.g CPU gov ,Under volt GPU and IO etc
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Ouch !!!! Its just Happening only due to Very unstable settings shown In the screenshot :p . I recommend you to research over google about kernel settings . If that not work then Use Stock kernel or you might just Damage your devise with instability .

Cheers

And Just Read OPs for more details
[Galaxy Note 4 Android Development (Exynos)] coolbuy:
Can anyone experienced help me with the ASV undervolt values. My processor ASV Group is 5. what is the stable value to undervolt both big and small cores at different clocks.
[Galaxy Note 4 Android Development (Exynos)] SaschaHa:
You have to find out for yourself. Every SoC is different even with the same ASV group. -50 mV should be ok in most situations.
[Galaxy Note 4 Android Development (Exynos)] hlcm151:
Oh , so my setting is stupid . unstable but it was save my battery.

I think it can't damage my device , because I didn't set Overclock Cpu. A57 700-1600mhz . A53 default. What do you think? Djmax88

I already set it back to up threshold 870 and down threshold is 256 . You see? :D

Thank you sir
[Galaxy Note 4 Android Development (Exynos)] djmax81:
Good that you realised .!!! But of course Bad settings will for sure cause harm to your devise or cpu in most cases .

And not just Over clock other settings also matters but Especially in yours it could have caused out sync all cpu core .

Note : A request to All users kindly do some Homework before flashing my kernel as i mentioned earlier and I'm running kernel developent not kernel tutrorial So plz stop posting about basic or Just flash Stock kernel if you can not Understand.

And there is nothing like " Best Settings " that i can help you sorry.

[Galaxy Note 4 Android Development (Exynos)] djmax81:
Yeah.!!! That can be seen once I'm free but No promises for f2fs as i was reading an article about seems it has flaws then Advantages with Touchwiz based firmware + Not much noticeable Performance tho.

But i got other plans too with my next kernel Release to Improve more performance once GPU port is done and i Already started looking into other stuff like CPU improvements and IO coz Samsung got bad habits just to Screw Good hardware in its kernel Source.
