So which is it? There is no difference in audio between versions.

Please read post #3 before posting, otherwise there is zero chance of assistance. Without user being proactive, I might just drop variant support.... I can't guess or know what exact steps you've already taken. Without having the device, a comprehensive approach is required by user.
[Galaxy Note5 Original Android Development] winbytrick:
Sorry for this confusion, skyhigh runs smoothly on my N920S, but once i flashed on my N920k it lost audio sound even with audio fix from Dr Ketan.

I only flash Skyhigh kernel without any modification
[Galaxy Note5 Original Android Development] UpInTheAir:
You still haven't read what I asked you to do and provide. Please read top of Post #3 again and post again once you have tried things there. I don't follow what custom ROM version is, so this is meaningless. What are your firmware versions etc, found in Synapse INFO section. All this is requested in post #3 so we don't have to ride the merry-go-round again............... Thanks
[Galaxy Note5 Original Android Development] UpInTheAir:
This should be in Q&A thanks. This is kernel development thread.

Actually, I've never noticed the CPU load/utilization path. I've seen one for all cores in the governor sysfs directory cpu0 and cpu4 etc. (cpu_util), but this will change upon governor change. Not really on my list. Perhaps you can search for it and let us know? It will be there somewhere...........

GPU frequency :

/sys/devices/platform/gpusysfs/gpu_clock

GPU utilization :

/sys/class/misc/mali0/device/utilization

My bad for skip post 3 requested info. Please refer below detail

Maybe I'm the first tester on N9200. I succeeded in flashing skyhigh kernel 2.6 on my J9 firmware N9200. However, synpase showed " No UCI support detected".
[Galaxy Note5 Original Android Development] UpInTheAir:
As per Post #3 !! Please flash your stock ROM and factory reset before bug reporting. How do we know it's not a ROM issue/incompatibility ? We know by testing with complete wiped stock firmware and flash as per thread requirements.

Did you: Device > settings > applications > Synapse > force close & wipe data ............................ before flash? If not, please do so and REBOOT

Edit. checked flash your N9200 on my N920C for test (no network as expected). Synapse works !! :) Installation instructions are there for a reason ..............
[Galaxy Note5 Original Android Development] Tomleungyuethei:
The same. Synapse shows "No UCI support detected." Maybe you should try directly that finding a N9200 device that is J9 firmware and than flash it once.
[Galaxy Note5 Original Android Development] UpInTheAir:
Care to donate one then .............................

really need an experienced Senior member with your device and able to understand & follow the installation instructions given. Reading and following post #3 is a must. There is no exceptions. Re-flash full stock ROM and factory reset > flash TWRP > flash > kernel, once you've done that and shown the screen-shots etc , you may post here. Thanks
[Galaxy Note5 Original Android Development] CanMan1:
I just noticed that the CPU capacity usage is a PerfMonhttps://play.google.com/store/apps/details?id=eu.chainfire.perfmon feature so I don't think I can find it.

Can this be added to the kernel/synapse along with CPU usage?

Another feature that would be useful in synapse is an option to log selected items (eg. GPU frequency) to a CSV with a configurable time interval.
[Galaxy Note5 Original Android Development] UpInTheAir:
Still would need the sysfs for standard cpu utilization.

Anything is possible. But would take a lot of effort. Maybe I'm capable, probably not. Probably time I'm not willing to invest to even try. There are other things needing fixing or patching. Sorry

[MENTION=3511708]UpInTheAir[/MENTION] - welcome back from your trip. (Okay, it's been at least a week, but I've been overwhelmed with my job as well..)

Just a reminder...

Did you have a chance to take a look at the synapse scripts and their tendency to mount the rootfs rw (and in many cases leave it mounted rw?) It seems to me that there's no good reason for mounting / as rw to begin with, as any changes would be lost immediately on reboot anyway.

You may have already corrected this since you returned, but I don't see anything in your changelog reflecting it (other than some vague "clean up" or "fix up" changes mentioned) (and I haven't had time to pull your updated kernel to check...)

Take care,

Gary
[Galaxy Note5 Original Android Development] UpInTheAir:
Actually I did start to check things, and required adding a lot more rw and r/o to the various scripts. This caused extreme slow down on Synapse app load. I never committed what I had done or implemented it as will take another look for easier way when things slow down over the next month. There is good reason for r/w as scripts won't work or "permission denied" etc when I start testing every function is Synapse. Changes are not lost, Synapse will apply on boot

BTW. My ramdisks are in gitHub, (as noted in change-log.................) trying to sort out other things (in between adding......................... multi-tasking)
[Galaxy Note5 Original Android Development] bala_gamer:
Flashed on my 920g, all working great. A bit choppy during scroll, will try fiddling with the settings in synapse.
[Galaxy Note5 Original Android Development] UpInTheAir:
I do notice just a little in Synapse. The more "live" values I put in, the more stutter. This is why I just tested adding CPU stats for all 8 cores. Make live all 8 because have plans to still try implement ktoonservative governor with hotplug. Adding all those live stats makes Synapse horrible. So left it out for now. Most of use don't live our lives inside Synapse, so I'm not too concerned for now. Once you let the kenrel settle down, and ROM caches are built, I don't see any stutter within apps, except if the data connection is too slow to DL the graphics and you try to scroll.

I haven't seen any in other apps though.
[Galaxy Note5 Original Android Development] UpInTheAir:
If anyone is using Xposed and DVFS disabler, can you please check to see if A53 LITTLE cores MAX frequency will "stick" after set anything other than 1500 (default/stock) Please close and then re-open Synapse to make sure.

Thanks

Preparing update, including new OAK ramdisk for N9200 [MENTION=3664604]aclan[/MENTION]
[Galaxy Note5 Original Android Development] LiL_Assassin:
Yeah stick for me, using Dr Ketens rom for sm+n920I
[Galaxy Note5 Original Android Development] UpInTheAir:
And HMP thresholds, or do they keep changing as well ? (dynamic values) every time you open/close Synapse.

Also, which kernel version are you using? SkyHigh v2.6
[Galaxy Note5 Original Android Development] carlitobahsoun:
yes..confirmed...using with or without xposed and a53 if sett it to 1200 for example and close synaps and reopen it still 1500

n920c/64g/genius vn rom v2/arter v10.0 beta2

---------- Post added at 03:19 PM ---------- Previous post was at 03:18 PM ----------

using 2.6

---------- Post added at 03:21 PM ---------- Previous post was at 03:19 PM ----------

yes keep changing as well
[Galaxy Note5 Original Android Development] LiL_Assassin:
Actually I take that back, it comes up with the tick or x for a second and then comes back to 1500 when setting it to 1300 also the hmp values do not stick. And yes 2.6. Happened on 2.5 also
[Galaxy Note5 Original Android Development] UpInTheAir:
So since the DVFS disabler has no effect, then the HMP thresholds are gone in next release. They are dynamic. As for the A53 MAX, don't know what to do with that yet. Anyway, is a waste of power efficiency and performance if set lower than 1500 MHz
[Galaxy Note5 Original Android Development] Zanr Zij:
Tested on my N920K and I can confirm the same problem: no incall audio

Model: N920K

Rom: N920KKKU2AOK1 ( Stock )

I also will test again tomorrow when try new stock Rom: AOK5
[Galaxy Note5 Original Android Development] UpInTheAir:
I'm in the process of testing next update. (EDIT: DL it myself) If you please get me the latest N920KKKU2AOK5 SM-N920K boot.img so I can compare to the current SkyHigh N920SKSU2AOK5 SM-N920S ramdisk base I'm using ? Maybe there is just a small change needed in default.prop or such .

Cheers
[Galaxy Note5 Original Android Development] Zanr Zij:
Sure I will send you boot.img once I flash new base in next 13hours.
[Galaxy Note5 Original Android Development] UpInTheAir:
I did you a favour and DL it myself. I have the boot.img and will check it soon. Hopefully there is something there.

SM-N920K v2.6 test

[MENTION=3241487]Zanr Zij[/MENTION] [MENTION=4085284]winbytrick[/MENTION] and all other SM-N920K users.

Please find attached a test version of v2.6 with modified ramdisk for K. If it does work, just hope it does not affect the S/L variants in upcoming v2.7 release. But only time will tell............. :fingers-crossed:

If a SM-N920S/L user wish to please test also, and give feedback here on connectivity. Thanks
[Galaxy Note5 Original Android Development] Zanr Zij:
Tested again but sorry to say that still the same: no incall audio.
[Galaxy Note5 Original Android Development] winbytrick:
Same here, no audio sound for OK5

[Galaxy Note5 Original Android Development] UpInTheAir:
Looks like I'll have to download the SM-N920K source and check the defconfig to see if any drivers are different.

Strange as S/K/L were compatible on my Note Edge. But this is Samsung.....
[Galaxy Note5 Original Android Development] UpInTheAir:
Might be something interesting.

arter97 are young genius bring us a lot of fix commit. but i wonder why samsung even can not optimize the chips which was develop by themselves.
[Galaxy Note5 Original Android Development] aclan:
Yeah, thx for your up-to-day work, I will keep watching this topic.
[Galaxy Note5 Original Android Development] anmolkakkar:
Tested the v2.6 and it is giving me a very High Android OS Drain (Not Modified with Synapse). It wasn't the case with v2.5.

PS: Installed and wiped dalvik cache and wiped cache.
[Galaxy Note5 Original Android Development] UpInTheAir:
Confirmed. This commit does work and prevents DVFS changing MAX freq. Great job by [MENTION=4898097]arter97[/MENTION] :good:
[Galaxy Note5 Original Android Development] aldoblaga:
looking forward for ver 2.7 :D hopefully you ll include a higher a53 frequency option as i believe it would further improve battery life by using more LITTLE cores :D right?
[Galaxy Note5 Original Android Development] UpInTheAir:
Not necessarily. At some frequency the A53 LITTLE cores become less power efficient and would benefit to migrate up to the faster A57 big cores to compete the task sooner.

It's possible to calculate it, but don't have the means. Possibly [MENTION=4167023]AndreiLux[/MENTION] would know the "cut-off" for our SoC ?
[Galaxy Note5 Original Android Development] aldoblaga:
well i keep seeing faster and faster a53 soc's and naturally assumed that (seeing as an avs 8 phone can work @ 925mv and 1500mhz) it would be beneficial for battery saving to maybe "up the ante" from 1.5 to 1.7 or 1.8 whilst maintaining the (at least) original thermal threshold/voltage (mine originally was 1062mv for 1.5ghz and i tested gundal's kernel once and i could get 1.8ghz with 1050mv... to back my claim up) ...of course mileage will differ from device to device (or asv group)
[Galaxy Note5 Original Android Development] UpInTheAir:
Nothing to do this that. As I said, it's about power efficiency and how long it takes to complete a task vs the power consumed. There is a cut-off frequency (under default asv values) where higher A53 is not always better (except on a benchmark for those with higher asv and less thermal throttling). But we are talking about power efficiency here...........
[Galaxy Note5 Original Android Development] aldoblaga:
i see...well i trust you ll make the right choices and decisions regarding making this device even more efficient!
[Galaxy Note5 Original Android Development] Manson79:
Hi,

[MENTION=3511708]UpInTheAir[/MENTION], I just noticied something, in Synapse for both A57 CPU and A53 CPU under governor tunables (for Interactive governor) we don't have the hispeed_freq setting (available in Kernel Adiutor, tested to see).

Nothing really important but it would be great to have an access to this setting (for those like me who like tweak) ;)

:)
[Galaxy Note5 Original Android Development] UpInTheAir:
I had omitted it from the kernel as I copied that part for Synapse directly from my Note Edge kernel. I recall the values being dynamic, so kept giving Synapse apply-discard bug.

I'll give it a test later on, but busy adding more support for devices I don't have. I also don't want to reboot my device for quite a while as I'm testing most of v2.7.

v2.7 CPU max frequency only compatible with Synapse app

.
[Galaxy Note5 Original Android Development] AndreiLux:
No
[Galaxy Note5 Original Android Development] UpInTheAir:
Thanks mate. So 1500 MHz is our sweet spot.
[Galaxy Note5 Original Android Development] aldoblaga:
yeah it seems that way but still, make 1600 available :)) with slight undervolting i think it will make a difference. that is if it s not too hard, just leave the option for me and anyone else who would wanna run it at 1.6...i really wanna test it and see if it does anything beneficial...
[Galaxy Note5 Original Android Development] UpInTheAir:
Check my gitHub ;)
[Galaxy Note5 Original Android Development] aldoblaga:
hehe i saw that but thought you d ditch the idea...hopefully it ll be stable and i m really looking forward to.testing it myself :D
[Galaxy Note5 Original Android Development] AndreiLux:
Not really. You want to look at the Y axis only.
[Galaxy Note5 Original Android Development] UpInTheAir:
So if I read it correctly this time,

So approx A57 800 MHz ~ A53 1200 MHz performance / Watts, and so on ?
[Galaxy Note5 Original Android Development] anmolkakkar:
Hi [MENTION=3511708]UpInTheAir[/MENTION]

Great job in creating a N920C Dual sim kernel.

Installed the v2.6 and it seems to have a lot of battery drain in the Android OS. Didnt used to happen when was on v2.5

Can you please suggest anything?
[Galaxy Note5 Original Android Development] aukhan:
[MENTION=3511708]UpInTheAir[/MENTION]

I must admit that your work has brought a lot of improvement here are is my stats so far with some minor tweaking no uv or ov nor any changes in GPS.

I am trying to see what is the best and suitable for me in terms of battery performance and stability, So far nor freezes or lags or random reboots.

Testing v2.7 on 9208. Look solid. sweep2sleep more effective than previous build. More option to customize. Running on default setting right now. Thanks sir. :D
[Galaxy Note5 Original Android Development] LiL_Assassin:
Very much like what you have done, thanks for the rock stable kernel and i like how much you update it. Stops my flash itch for awhile :P but then you bring out another. So yay :P

[Galaxy Note5 Original Android Development] uzzz2004:
A stupid question on the sweep2sleep how it works? What for? From what I understand I need to reactivate the screen with a swipe from left to right, but does not work
[Galaxy Note5 Original Android Development] UpInTheAir:
Just a reminder to read the change-logs properly !!

It is obvious I need to amend Post #1 with the correct version.... ;)

Read Synapse . Also always search the thread where you will find help and screenshot on the subject. ..
[Galaxy Note5 Original Android Development] kumbangdesa:
You need to use Synapse app to activate that function. It for screen off the phone without using power button.
[Galaxy Note5 Original Android Development] uzzz2004:

Hi,

[MENTION=3511708]UpInTheAir[/MENTION], I'm running the 2.7 kernel since a few hours and all is fine, no issue (at least for what I've tested) :)

Performance is perfect (smooth and fast), no feedback on battery life yet but it seems ok with my settings and my use for the last hours I tested (even if I don't really care about battery life, I'm more oriented on "performance").

A little Antutu (yes I know with the 5.7.1 and not the last 6.0 but I need to compare with my previous benches), no overclock yet and no undervolt, just some tweaks here and there:

Awesome job on this 2.7 and thanks for the A53 overclock :good::good::good:
[Galaxy Note5 Original Android Development] xerostratos:
awesome!!!

V 2.7 is awesome max freq at 2.2 A57 min freq 500 , A53 1.5 min freq 200, some tweaks with interactive governor and undervolt-60 all freq, gpu at 772 with undervolt 8 steps down!, memory also undervolt 3 steps if undervolted a little more the score of ram speed and operation drops down, HPM voltage margin 31250 µV for all, zero reboots, zero freezes battery drain is unbelievable! Very happy !:fingers-crossed: antutu not last version so we can compare with other tests. New one huawei mate 8 in terms of specs is a ****ing beast!!!:D:p

P.D when try to benchmark with a higher freq speed. Antutu make 1 of 2 things! Stop benchmarking when 3d rendering! Or if I keep undervolt at default it ends but with a poor score ! Kind of weird uhhh!
[Galaxy Note5 Original Android Development] Manson79:
[MENTION=6731039]xerostratos[/MENTION], awesome score with a slight overclock for A57 CPU and GPU :eek: :good: ;)

Can I ask your CPU Temp at the beginning of your bench ? Thanks :)

Before I reset all my Synapse settings (yep it could save me 5 mins :D), could somebody post the default Kernel Entropy values that came with SkyHigh kernel please?

In Synapse it's under Advanced, I need the Read Wakeup Threshold and Write Wakeup Threshold... Thanks in advance guys ;)
[Galaxy Note5 Original Android Development] aldoblaga:
my scores in antutu 6 @2.4 ghz and 1.6ghz with 852mhz gpu and around -100mv undervolting - best score i could get with a cool device (starting temps of around 27-28 celcius)

well i tested and not cause by that app

still can swipe to lock
[Galaxy Note5 Original Android Development] kaiyen8804:
sad:( but still thanks!
[Galaxy Note5 Original Android Development] UpInTheAir:
I don't think you followed the installation instructions exactly. ...

1. Device settings > Applications > Synapse > Force close + clear data

2. Re-flash v2.7

If this doesn't work, maybe something with your ROM and need clean install stock and test without any changes or additions.
[Galaxy Note5 Original Android Development] kirasan13:
any performance tips yet?
[Galaxy Note5 Original Android Development] UpInTheAir:
So did it work or not?
[Galaxy Note5 Original Android Development] kirasan13:
he did follow no.1 doesnt work and i suggest him to get ok8 than flash 2.7 but he say will try reflash 2.7 1st

still no reply from kaiyen8804
[Galaxy Note5 Original Android Development] kaiyen8804:
My sweep2sleep works:D

The solution is:

Synapse->Power Suspend->uncheck the PowerSuspend State

I don't know why this setting makes sweep2sleep fail, but anyway, everything is fine now!

And what about the latest OK5 from which the ramdisk is based?

If that doesn't work, I'm going to drop future support for all Korean variants. Users (few they are) haven't bothered to even post if even the S or L variant are OK. ...

I may as well drop some other variant such as N9200 too. No one replied for my request in v2.7 release post.

I can't do any more than using the latest "international" compatible source at hand (in this case, N920T) and ramdisks. I don't really want to mess around merging all sorts of source from all over the place. I don't have the time for it.
