Only one post above yours! Sorry guys, i don't want sound rude, but this is a dev thread, not an ask question that you could google or answer yourself just reading the posts here. If you don't know the basics and most questions asked here are basic knowledge, if you want to use a custom kernel, you should better use the stock kernel!

[Galaxy Note 4 Android Development (Exynos)] got2trythis:
No the speakerphone does not work. The speakers work but if you use the speakerphone during a call people do not hear you when you talk. It is a speakerphone bug and not a speaker bug.

In my case, I had a 5.0.1 custom rom flashed on my Note 4 and flashing this kernel made it get stuck into bootloop.
[Galaxy Note 4 Android Development (Exynos)] pappschlumpf:
That's a synapse feature, if there's a random reboot oc/uv settings are reverted. Have you tried to clear synapse data and let it work with kernels stock settings first? That normally should work stable. Not every device oc's/uv's like the other. Maybe ypur device is only operating stable with stock frequencies and voltages.

[Galaxy Note 4 Android Development (Exynos)] asia559571:
Some info needed

Hi MEGAX91. I've asked but didn't the info I wanted, (I have searched the whole thread!), Question; Is there a V.13 Stock sound with GPU OC?

If Yes please can you give link, if only Wolfson version available does the Wolfson version have any bugs regarding call's & microphone? also, does the V.12 come in the four flavours?

I've looked at 4PDA, my Russian is terrible so I may be wrong but I only see GPU OC versions mentioned. Your answers would be greatly appreciated!:o
[Galaxy Note 4 Android Development (Exynos)] MEGAX91:
version 12/13 are available only with Wolfson sound & GPU OC.

if you need Stock sound , use version 10.
[Galaxy Note 4 Android Development (Exynos)] asia559571:
WOW! that was a quick reply, but do you know if sound bugs with the Wolfson have been fixed?
[Galaxy Note 4 Android Development (Exynos)] MEGAX91:
the issue has been fixed in Perseus kernel v14.( Feb 2 )

Samsung is using the audio SoC's equalizers (EQ1,2,3) to synthesize audio input from all 3 microphones when in speakerphone communication mode , This caused a problem as old Wolfson was actually using equalizer 3 & 4 for the speaker at all times but the audio framework was using those at the same time, resulting to funky audio routing.
[Galaxy Note 4 Android Development (Exynos)] asia559571:
Whats your opinion of the Perseus as compared to the Ultimate?
[Galaxy Note 4 Android Development (Exynos)] got2trythis:
Thank you. Perseus Kernel is not available though for our device at least not on XDA. Do you know if the sound fix will be applied to Ultimate sometime soon. Version v..15 is almost perfect out of the box and without any modifications. Great performance and fantastic battery life. I am hoping the sound will soon be fixed or please give us a version with stock sound.

[Galaxy Note 4 Android Development (Exynos)] MEGAX91:
U.K v2 had 900MHz GPU OC / v3 Had 800MHz GPU OC.

after two days of tests no glitches have been identified, works for me is absolutely stable.

with overheating significantly increased frequency throttling GPU, so performance is not reduced as much as the battery drain
[Galaxy Note 4 Android Development (Exynos)] Azcaron:
Yes, and GPU will stay in that frequency for about 10 sec and then will dramatically throttle down because of overheating: useless.
[Galaxy Note 4 Android Development (Exynos)] MEGAX91:
in version 2/3 there was no GPU Voltage/Clock control.

undervolt can decrease heat & reduce power consumption.

Just woken up and about to go through some code, thank you for being brave enough to flash it anyway!

Is there anything else at all not working? If it's just the Mobile data, then it wouldn't be too hard to create a U variant of the kernel.

Using meld to compare the stock 910u source and the Ultimate kernel source right now. At first glance, it appears to simply be a few files that need to be swapped before the kernel is compiled, as both sources include configs for the various exynos models.

[Galaxy Note 4 Android Development (Exynos)] UpInTheAir:
In general use, there's a high chance none of those frequencies well ever be used. You can check time-in-state.

If you benchmark and observe actual live GPU frequency, I bet that device will have severe thermal throttling at those frequency (unless you are in a very cold environment). You try "Manhatten" in GFXBENCH, that will really test it out ;)

There isn't such a thing as "undervolt" for frequency above 700 MHz (edit: 730) because any are just made up. They don't exist in source!

Edit, still night be worth a try though. A device with a high asv_group could possibly take advantage.

Ultimate Kernel v.16

change log: ( Google Translator for the win :D )

-Linux 3.10.71

-GPU Freq Control (adjustment of the maximum / minimum frequency GPU) - the author Halaszk, for which many thanks to him - no longer need to do the overclocking kernel / no, now themselves can change the frequency at will.

-GPU TMU (thermal manager) on / off control (is there any effect from this, not yet test)

-Update Wolfson Sound Control, with a working microphone at the handsfree (sound quality through headphones is not a test may deteriorated - email, music lovers, as it was)

-Updated Ramdisk (thanks UpInTheAir) - added FS Trim (under FS), Fixed saving / restoring of profiles and the kernel itself (that saved profiles / core appeared in the selection list, you must restart the phone)

-melkie fixes

About gpu oc I think it will be useless for most people on most situations. You would need to use it for like 2 minutes or in an extremely cold place. But still, it's always nice to have options to test.

[Galaxy Note 4 Android Development (Exynos)] got2trythis:
To be honest all of these Benchmarks are invalid. The tool is not consistent in scores on every ROM and every Kernel. I have tried every ROM(Every one on this site) and every kernel (Adam, Ultimate, Stock) and the Benchmark tool score ranged from 28K to 56K for every kernel with no modification or changes. just running the tool back to back to back. So nothing you are changing from OC to Governor stuff is going to be measured reliably. It is the tool with Lollipop on Note 4. So all of these high scores you see do not mean anything and all of the low scores do not mean anything either. I got a score 56K on stock rom and stock kernel - but I also got 28K one time. I just run it for v.16 unmodified (everything default) and I got 55K on both Keatan and Masik ROM. So here you have it, stop wasting time running these tests. My .02 cents.

I have noticed that if the screen is set on auto brightness and you run the tool in a bright environment, you will get better scores :)

[Galaxy Note 4 Android Development (Exynos)] pappschlumpf:
Are you guys really use bioshock as your daily driver? On my device bioshock and conservativex are driving A53 cores on highest frequency nearly all of the time. Only the interactive based governors are clocking down the cores much more often. Impuls, intelliactive and interactive are working ok. Looks like tne other governors don't like the constant cpu load lollipops androidsystem and systemui generate. Around 7 to 10% each. I've seen that with all 5.01 ROMs, including pure stock without any apps installed. Hmm, I can npt believe that batterylife is good with mentioned governors if i look how they behave on my device. Your thoughts, opinions please!

XDA & GPL - Kernel source

I think this has been asked a couple times before, but as it seems to be continually overlooked, forgotten or dismissed, may I remind the OP (or thread maintainers) of your responsibilties.

Please update the OP to reflect the actual kernel and features etc (This is development thread........ )

Please update your source. You are continually breaking GPL and XDA rules by not releasing this. Source v0.7 is just not acceptable. I think you are posting kernel v.15 (or something in thread) and v.10 in thread title.

It would be appreciated if you make your source changes available via github repo like most others (and myself) do. What have you got to hide? We can all (devs/users/hacks etc) learn, contribute directly or indirectly through our own projects. Uploading a zip is not reciprocating sharing ;)

I thank you for your understanding.

I actually don't think that [MENTION=309864]mcaserg[/MENTION] meant to release this kernel on XDA at the first place,

as you see it, this thread are not posted by himself, and most of the time the newest version was shared here by others from 4pda.

But yeah, it will be awesome if he can create a repo on github, just easy for other dev to cherry pick.

Another but, as he is always release newest version on 4pda most of the time, i don't think all the XDA & GPL things could make any changes.

[Galaxy Note 4 Android Development (Exynos)] UpInTheAir:
It's not about "scaring" anyone away, it's about compliance. Whether he releases his kernel at the North Pole, he still MUST release his kernel source for the exact zImage binary of release. If they can't do this, they aren't meeting the LEGAL REQUIREMENTS.

As I said, what is to hide? Why not publishing on a git repo?

The sad fact is, if the maintainers don't keep up with release of source code, this thread WILL be reported to the XDA Moderation Team. They have been asked by a number of members on more than one occasion, so there is no excuse. Maintainers threatening to close the thread because they won't (can't be bothered to) meet the XDA and GPL requirements is lame. Let's not hope it comes to that, because it doesn't need to.

[Galaxy Note 4 Android Development (Exynos)] Fieah:
