Picture of mine N9208

Sorry when using xiaolu kernel NFC work.. But Nevermind I don't used it... ☺
[Galaxy Note5 Original Android Development] Abu-khulzat:
Finally my phone sleeps with the version 1.9!!!
[Galaxy Note5 Original Android Development] UpInTheAir:
To be clear. What exactly doesn't work?

1. Device settings toggle switch , or

2. Actual payment
[Galaxy Note5 Original Android Development] asmen5:
I think both of them
[Galaxy Note5 Original Android Development] asmen5:
Both of NFC payment
[Galaxy Note5 Original Android Development] edwardob:
used SM-N920I_TW_LL_v1.9.zip

tried it on my n9208 ...but not recognising sim cards ...ie both.. tawain model

nfc non funtioning

everything else working wifi ok

maybe i downloaded wrong one?????

yes wrong one ....SkyHigh_kernel_SM-N920C_TW_LL_v1.9 is the right one

nfc shows on but cant change in settings so something not right ..i dont use it anyway

nfc button switch stuck on...but not actually working

broke the rules a bit ....i have xposed installed ...some tweaks ...not much

hope info has been useful to this thread

just did antutu benchmark and was 20 % higher than previuos and kernel not even settle down yet

sview cover nothing working as in no accesories setting anymore?

SM-N9208_SEA support

Add official variant support for SM-N9208_SEA

Thanks to the users for providing feedback which lead me to revisit the source ;)

The ramdisk is essentially the same as SM-N920C and I believe I have fixed up the source defconfig (build instruction set). When compiling for this specific variant, this caused no SIM to be detected and no NFC. etc.

Obviously I'm unable to test on SM-N920C. So always backup your boot.img in TWRP before testing.

SkyHigh SM-N9208_SEA v1.9 kernel on testing, network both of is Ok ?, NFC still same as 'C" kernel not work, thanks for your hard work

??
[Galaxy Note5 Original Android Development] UpInTheAir:
Thanks for reporting.

Please check with stock factory reset official ROM thanks with no modifications etc.
[Galaxy Note5 Original Android Development] edwardob:
thanks I'll give it a go

NFC...same not working

sview cover not ...working. .........accessories not showing in settings

but mine not clean ROM.......
[Galaxy Note5 Original Android Development] Elmar1801:
I have a Stock OH4 N9208. Kernel runs great except NFC. NFC can't be turned on. I am using it with Timesheet.
[Galaxy Note5 Original Android Development] Mhmad Hany:
when i flashed the last version my headphone not working in calls ???????
[Galaxy Note5 Original Android Development] UpInTheAir:
I have no idea what device you're referring...

Post #3 should help you provide the information required.
[Galaxy Note5 Original Android Development] UpInTheAir:
Appears S-view and Accessories are related in ROM. Perhaps the kernel driver is wrongly compiled version or ramdisk permissions incorrect. Same for NFC driver.

Unfortunately no time to look into it further as I'm preparing to head away on professional commitment for an extended period. There may be one last release to v2.0 before that :)
[Galaxy Note5 Original Android Development] Mhmad Hany:
N920CD
[Galaxy Note5 Original Android Development] edwardob:
thanks..... probably not to many people with sview..... so could be problem on other roms

NFC is probably the big one for many
[Galaxy Note5 Original Android Development] UpInTheAir:
Thing is, nothing can be identified as a bug unless confirmed on 100% stock factory reset ROM. Unless users bother to help themselves, I won't bother either chasing things that might not be even kernel related. This method answers many questions for a device I can't actually test, otherwise things may never get resolved or in a timely manner. ;)
[Galaxy Note5 Original Android Development] edwardob:
I get it.........
[Galaxy Note5 Original Android Development] UpInTheAir:
What I'm working on before I had to go out today :)
[Galaxy Note5 Original Android Development] edwardob:
looking for to it
[Galaxy Note5 Original Android Development] UpInTheAir:
Good work-around for users, but not a fix.

I'll need proper feedback as requested from someone though, because if that doesn't happen, I drop support all together. I'm only doing this as a favour, and I have only so much free time and particularly for a device I have no vested interest.

If someone could please post the stock boot.img from N9208XXU1AOH4 so I can double check the ramdisk against what I'm currently using. Thanks
[Galaxy Note5 Original Android Development] LiL_Assassin:
I know this is a dev thread and not a normal question. I apologise, I have my gpu set to lowest of 100, what's the lowest someone's underclocked it to? And how do you tell when it has instability? As I have hit these options with no problems at all.
[Galaxy Note5 Original Android Development] danon.brown:
It will lock or reboot. Mine is at 100 also with no issues.
[Galaxy Note5 Original Android Development] LiL_Assassin:
How much have you undervolted? No locks or reboot with how much underclock I have
[Galaxy Note5 Original Android Development] danon.brown:
It won't until you start messing with the voltages of the big/little cores.
[Galaxy Note5 Original Android Development] edwardob:
the rooted image attached is the one we all been using with success but its pretty basic and we dont know where it came from

the second is from official tawain n9208 dual sim firmware

[Galaxy Note5 Original Android Development] LiL_Assassin:
On my old s3 I had at the time. If I undervolted the gpu, it would cause artifacts or lock ups with the phone. (wanted to see if it was the same for this device. So I don't understand?)
[Galaxy Note5 Original Android Development] UpInTheAir:
I would advise anyone playing with frequencies and voltages to disable "apply on boot" on Synapse settings (3 dots top right hand corner) until stable settings found.

You could set both min / max frequency the same, and then adjust voltage to test stability. Then add +25 mV when done.
[Galaxy Note5 Original Android Development] LiL_Assassin:
Is it actually registering the underclock? I feel like I should have a reboot by now.
[Galaxy Note5 Original Android Development] danon.brown:
Play a game or something
[Galaxy Note5 Original Android Development] LiL_Assassin:
Pic
[Galaxy Note5 Original Android Development] UpInTheAir:
It definitely works, just a quick test to show the difference both min/max ;)

266 MHz

160 MHz

100 MHZ

Setting 100 MHz voltage to Synapse minimum of 500 mV results in reboot when load the GPU.

Don't forget a lot had to do with asv

_group. Info in Synapse INFO section.

You need to load up the GPU and under stress. I used that bullet app
[Galaxy Note5 Original Android Development] LiL_Assassin:
Understood. I tried 500, instant reboot. So from stock values, I turned the 100 gpu, down 18 times from stock value and the rest by 6. Works fine. I might wait till your next update and then use it to save my profiles and then go from there so it's easier.
[Galaxy Note5 Original Android Development] Elmar1801:
You have a PM
[Galaxy Note5 Original Android Development] UpInTheAir:
Thanks, confirmed same as I'm using.

good update this 2.1...

sview cover working........ NFC switch working...will test with another phone soon

do far so good!

confirmed.... NFC working....

looks like a winner
[Galaxy Note5 Original Android Development] asmen5:
Same here on N9208, NFC on/off work
[Galaxy Note5 Original Android Development] edwardob:
now to figure what I can do with synapse ????
[Galaxy Note5 Original Android Development] LiL_Assassin:
Give settings ago, and see if you can find what you like. If you underclock, or undervolt, make sure to unclick set at boot.
[Galaxy Note5 Original Android Development] edwardob:
problem is I don't know what I like.. cause I don't have a clue... where to start
[Galaxy Note5 Original Android Development] LiL_Assassin:
Lower gpu to 100 and see how much you can lower it by? :p...i can lower it 18 times. I haven't tested it more than that. Put the power saving functions on too.
[Galaxy Note5 Original Android Development] LiL_Assassin:
I haven't tested these yet.. But no reboots these levels.. Lol
[Galaxy Note5 Original Android Development] edwardob:
lower wha to 100. min freq. or Max freq

what you mean lower it 18 times???

when you look at some many settings.... instruction need to be more specific
[Galaxy Note5 Original Android Development] LiL_Assassin:
Sorry, I lowed the 100 clock value, I underclocked it from the default to 556, when the default is roughly 668? Or something like that
[Galaxy Note5 Original Android Development] UpInTheAir:
There are no specific "defaults" for CPU or GPU voltages. It depends on your "build quality" as defined by your asv_group / asv_summary. So not all are created equal. Users need to post the their asv_summary when considering voltage adjustments etc.

Read the INFO section in Synapse and Google the rest ;)
[Galaxy Note5 Original Android Development] LiL_Assassin:
I know, I was just saying how far I could get it down and he didn't know what he wanted to do. So I just wanted to see how much someone else could under volt it
[Galaxy Note5 Original Android Development] garyd9:
[MENTION=3511708]UpInTheAir[/MENTION], would you have any objection if I took your kernel code and tried to get it working as SEAndroid Enforcing? I honestly don't expect to have much luck, but you have a "known working" kernel (despite Samsung's efforts to make it nearly impossible) and it's not as modified as many of the other kernels floating around.

I have a particular need to learn SELinux/SEAndroid (and I learn best by doing.)

I wouldn't distribute it, but if I actually manage to get it working, I'd be happy to send the changes back via pull requests.
[Galaxy Note5 Original Android Development] UpInTheAir:
My gitHub is open-source. I had my Samsung Galaxy Tab S kernels patched so Enforcing <> Permissive switchable with Synapse control. I just run out of time to try implement anything else for now. I'm travelling and won't be near a development PC for quite an extended period. Certainly this month and maybe most of the next.

I merged in newer source this morning and enabled multipath TCP. I need (or someone else can) to research these additional multipath TCP algorithm.

I might be able to upload just the N920C kernel from my device at some point.
[Galaxy Note5 Original Android Development] kumbangdesa:
Any chances that we can get more gorvernor on next update?. Thanks
[Galaxy Note5 Original Android Development] UpInTheAir:
Interactive Is by far the best all round and stable governor. Fancy names don't make them better or suitable for Exynos HMP. In future, I might take a look at ktoonsez governor. I have said this all before though. ..... and no chance for a supported update for quite a while.
[Galaxy Note5 Original Android Development] edwardob:
here's my screen shot asv values......I know you said google... but what should I google
[Galaxy Note5 Original Android Development] garyd9:
Playing with kernel... it appears that the synapse tool is remounting the rootfs as r/w on startup, and leaving it r/w.

If I deprive synapse of su access, the filesystem stays r/o.

Posting this here as I'm not really sure if this is something that the kernel or boot image has anything to do with.

Take care

Gary
[Galaxy Note5 Original Android Development] eousphoros:
In a way im glad it was the gcc version. Ive been using the linaro compiler and it explains why i wasnt seeing the incall reboots.
[Galaxy Note5 Original Android Development] UpInTheAir:
Probably one or more of the UCI action scripts don't have r/o. I'll look at it when I return home.

No issues since changing. All looking good. :)
[Galaxy Note5 Original Android Development] garyd9:
Please pardon me while I play...

I'm not at all familiar with synapse or UCI, so I'm doing this the old fashioned way: grep. The following "scripts" all seem to remount the rootfs as r/w and leave it that way:

res/synapse/actions/cortex_start

res/synapse/actions/network

res/synapse/actions/mirror

res/synapse/actions/security

res/synapse/actions/devtools

Not sure why they remount the root fs to r/w - none of them seem to do anything with the rootfs, but perhaps they store some kind of config file there. (It couldn't be persistent configuration, as rootfs is destroyed on reboot.) Should these be remounting back to r/o when they're done or is something else supposed to do that? (Or perhaps they shouldn't be remounting to begin with? I have no idea.)

I'm also confused by res/synapse/uci. This looks similar to an init.d type script, and the "reset" action remounts the rootfs to r/w, deletes a config file (that's on the rootfs), and remounts the rootfs to r/w again? Should that second remount be back to r/o?

So.. just trying to patch this up for the few weeks you'll be gone... it seems to me that the ONLY thing that should be remounting the rootfs is the /rest/synapse/uci script's reset action, and that it should be remounting to ro after deleting the config file. Does this seem correct?

EDIT: Okay, after actually looking at the scripts in res/synapse/actions/, I see that they do write temp files to /res/synapse/SkyHigh/, so I'm guessing that they should be remounting back to ro when they are done.
[Galaxy Note5 Original Android Development] garyd9:
v2.1 ("n920i" device) seems to crash/reboot when powered off and charging. (system firmware doesn't seem to matter. If this isn't 100% reproducible for others, let me know and I'll dig into it on my own device.)

Edit:

Striking out the text so everyone reading the post doesn't reply. (It's been replied to and it's not 100% reproducible for others.)
[Galaxy Note5 Original Android Development] LiL_Assassin:
I just use 2.0 and that never happens for me
[Galaxy Note5 Original Android Development] garyd9:
Okay, it sounds like something I'll have to troubleshoot on my own device. Thanks for letting me know it doesn't repeat for you.
[Galaxy Note5 Original Android Development] CanMan1:
Will the SM-N920-8_SEA (XXU1AOH4) kernel function the same on SM-N920-8_TW (ZTU1AOH4, Taiwan)? If not, can you add support for this device? I'll be able to test it when I get my phone from Taiwan in 1-3wk.
[Galaxy Note5 Original Android Development] cezeff:
I have this very same question... I'm running the Taiwan version as I live in Okinawa and wondering if the sm9208sea kernel would have the same makeup of the sm9208tw? Currently I am on a rooted stock kernel that has been running like a champ, yet looking for a kernel with some performance and enhancement features such as this one... I can provide source for current kernel I'm on if need be...
[Galaxy Note5 Original Android Development] UpInTheAir:
Yes. Should be r/w then once script is run r/o. Probably just need to add it down the bottom, same as some others. CortexBrain is not used right now. I'll add this later.

I haven't had any other reports in thread or PM using stock unmodified firmware on 2.1
[Galaxy Note5 Original Android Development] winbytrick:
hi mate, is there any way to support Note 5 Korean version N920K in this kernel?
[Galaxy Note5 Original Android Development] UpInTheAir:
Please read post #3

for what's needed. BUT, I won't be able for a while as I'm away for some time. Wait until then

As above

I don't know as I've not compared both variant defconfig (compile instructions for drivers/modules etc) or ramdisk

I won't officially support anything until I've done at least that. Maybe it's OK, maybe not.

Kernel source:

Anyone using my kernel source from my repository in gitHub, please note that the commits after v2.1 (source merge) causes touch screen issues and won't lock screen when S-view cover is used.

I would suggest you revert the changes to v2.1 which doesn't have many issues.
[Galaxy Note5 Original Android Development] hshah:
I have noticed more of a battery drain by the kernel (according to GSam Battery Monitor) with v2.1 compared to v1.9. I am using a N920CD with Stock ROM.

Hello, my wifi speed is about 30 mbps, but only on my note5, its 15 mbps.. on every other device, full speed.. tried resetting router and phone and flashed fresh rom.. as far as i know, kernel controls wifi, is there a way to fix this issue through the kernel? I tried the TCP algorithms, they did not do anything.
[Galaxy Note5 Original Android Development] UpInTheAir:
Did you try stock?
[Galaxy Note5 Original Android Development] Mohammed779:
Yes.. both stock and this custom one..
[Galaxy Note5 Original Android Development] garyd9:
The issue I was experiencing was due to me making changes to the ramdisk... I got the idea to remove scfs_support from the mount options in LPM (as initiated from one of the init.*.rc files) which apparently wasn't a good idea.

Once I removed MY error, it worked fine.
[Galaxy Note5 Original Android Development] Megaflop666:
Anyone else see in synapse on A57 CPU, where core 2 likes to bounce back and forth between -1 Celsius and whatever the other three cores are currently at?
[Galaxy Note5 Original Android Development] UpInTheAir:
The "-1" is intended in source. This was also the same on my Note Edge kernel. When the CPU is loaded, the "real" figure is given. Don't know why, and due to time constraints, haven't bothered to look into it or try understand exactly why.
[Galaxy Note5 Original Android Development] Megaflop666:
Only other things I've noticed is that on the latest darthstalker build, when running this kernel I get constant fc on message enhanced features and I always get a fc of system ui at boot up. I don't know if it's something new in Jovy's build or what's causing it.

I'm running the 2.1 kernel since it has been released on my 920I device without any problem. Synapse settings on default and stock ROM just with another launcher (Nova) and some root apps. I'm happy so far. Thanks for all the hard work and keep up the good work.
[Galaxy Note5 Original Android Development] Mhmad Hany:
still there is a problem with the calling the other person couldnt here me but i here him ether from the phone itself or from my headphone ??????? plz fix this problem in all the versions of the kernal
[Galaxy Note5 Original Android Development] UpInTheAir:
If the kernel works with earlier ROM versions or stock ROM, then the issue would point to a ROM

incompatibility or issue. He has advised me maybe a toolchain needs changing, but I don't have issues on my stock N920C ROM.

The kernel supports USB OTG, but I don't have the hardware or access to development tools to try. User is required to check for themselves if it supports both. ;)

Thanks for the feedback :)

I have the same issue on my N920C, so of course would like to see it resolved. It doesn't bother me so much as don't really use the earphones during calls, but others differ.

I've already posted more than once that development has been suspended due to professional commitments and won't resume for a good while. Would suggest to either live with it or use another kernel until the cause is found and rectified. :)
[Galaxy Note5 Original Android Development] Zanr Zij:
This kernel seem works with Korean variant ( my N920K ). But i have problem with incall sound: no sound at all. I have to press "Extra volume" button to get the sound.

Back to arter97 kernel and all work fine.

Keep it up! I heard that this is battery friendly kernel.
[Galaxy Note5 Original Android Development] UpInTheAir:

[Galaxy Note5 Original Android Development] CanMan1:
The SM-N920-8_SEA 2.1 kernel seems to be fully functional on my stock BRI (Taiwan) N9208ZTU1AOH4. However, I haven't tested dual sim or stability.

Does the kernel have fuse support so it can be used with EDS?

Attached is latest (2AOJ3) stock boot.img
[Galaxy Note5 Original Android Development] UpInTheAir:
Should work, but as i don't use it, you'll just have to try for yourself
[Galaxy Note5 Original Android Development] d.cortez:
not sure what EDS is, but the dual sim feature works fine with the SM-N920-8_SEA 2.1 kernel. i've had good results and no rebooting with this kernel. the one thing that really appeals to me is the ability to easily increase the earpiece volume using synapse. the only drawback i've encountered - as noted by UpInTheAir - is the inability to use headphones for phone calls; you cannot hear the other party through your earphones.
[Galaxy Note5 Original Android Development] edwardob:
is attached file of latest kernel.... rooted...???
