Yep. Did a complete clean install (had tons of issues which didnt get solved by just reinstalling rom)

1. Wipes and formats of everything including system. (few times just in case)

2. Flashed G903FXXU1BQC1_G903FOXA1BQC1_G903FXXU1BQC1_HOME.tar.md5

3. Started it up a bit (just to make sure it wont give me any updates, it didnt)

4. Flashed twrp-3.1.0-0-s5neolte.img.tar

5. Flashed your Shedrock.1.7.0.0.BQA2.zip over twrp. (Didnt do stock kernel or modem and didnt do Boot scripts, other than that I selected everything)

6. Flashed your kernel (Beta 4 from post #6867)

7. Now I did try flashing SuperSU-v2.79-201612051815.zip just to test, but no root. So I flashed BETA-SuperSU-v2.74-2-20160519174328.zip and root available. (is this the latest 2.74? didnt find any other version than BETA)

After rooting with SuperSU v2.74, it became permissive by itself. So there was no need for any switcher.

Adiutor shows 6 Governors. Didnt try messing with them yet.

Are there supposed to be any other advantages with your kernel other than the ability to change governors?

Battery at 70% after a day with playing music over bluetooth speaker and a bit of browsing and even 2 restarts, which is more like normal or maybe even better. (was barely 40% before, with my issues, or had battery drain issue randomly, but thats all probably cause I had it really messy)

But I barely have all my apps set up yet, so I cant really compare to my usual use.

The only issue that persisted was my music randomly stopping like every 1-5 minutes. Which I found really weird as its now completely clean and I had the issue even before this clean install, pretty much since I updated to Shedrock.1.7.0.0.BQA2. But I did reinstall my beta PowerAmp and in the following short time of testing it didnt stop. But then PowerAmp should have been a clean new install, so I got no clue. But I will keep watching it.

Just if anyone else has this issue of music simply pausing every few minutes, let me know.

Think it was happening with screen on or off too...as my first theory was the damn Doze mode, which just loves to screw with things, especially alarms, with which I had some awful issues since Android 6...but Iam only guessing its because of Doze mode, even been reading about issues with Doze and alarms.

Thanks for updates :)
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
Thanks for the report.

Sorry but i am concentrating on kernel now.

Yep shedrock rom makes kernel directly the kernel permissive through an init d script. But my kernel is enforcing by default

Changing governors is not the only thing. Schedulers too. TCP algo too. But it has (will too) many fixes, Voltage control.... And has a linux kernel update to max branch currently (3.10). you can see updates on my github.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Emre67511:
Tested all governors

they seem all to work normal except conservative and power saver.

Conservative causes random reboots.

power saver keeps the cpu frequency very low all the time so that you can't use heavy apps. shouldn't the cpu frequency go higher when using heavier apps even in power saver mode ?
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:
Gov is back to interactive
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
So i will disable conservative governor atm. About Powersaver, no. Use OnDemand instead (lol). More to come....
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
Alone ?
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:
alone LOL, the last i tried was conservative and after about 2 hours it was changed to interactive (checked every 30 min)
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Emre67511:
maybe it changed because your phone rebooted ? because my phone reboots when I use conservative
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:
Don't think so, i always reboot after changing things in kernel
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Emre67511:
tested conservative again and it works on the last 4 cores (the big ones) but not on the first 4 cores(little ones)

when I make the first 4 cores conservative their cpu frequency is always at the maximum and my phones reboots after some time. when i only make the big cores conservative everything works.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:
Don't care about the 4 cores, normally there are off.

[Samsung Galaxy S5 Neo Guides, News, & Discussion] Neoony:
Back to my music stopping issue.

Next day, connected bluetooth speaker and my music keeps pausing every 1-5 minutes.

So am thinking this has something to do with bluetooth. As without it it doesnt seem to pause.

But I will try headphones and nonbeta poweramp or other player later.

But quite annoying issue.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
So. Some news.

New version (sources not yet up to date) currently have:

- a few new governors: a corrected preservative, zzmove, alucard, conservativex (which replaces conservative), bioshock, bluactive, barry allen, dancedance, darkness, hyper, intelliactive, lionheart, nightmare, pegasusq, ondemandplus (which replaces ondemand), smartass2, wave, wheatley, mythx.

- Drivedroid patch (https://xdaforums.com/showthread.php?t=2196707)

- frandom implement

But before making it public, i want to implement Power Suspend and lz4 compression and a few fixes on source.

Remember you can see latest changes here: https://github.com/ShedrockN4/s5neoltemax/commits/test
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:

[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:

[Samsung Galaxy S5 Neo Guides, News, & Discussion] Neoony:
My music pausing issue:

Using bluetooth speaker. Music pauses in 1-5 minutes.

Using headphones. Music pauses in 1-5 minutes. (so its not only bluetooth)

I just tryed another app for music with both bluetooth speaker or headphones. Music pauses in 1-5 minutes.

Phone speaker seems to work fine. EDIT: or maybe not, just had a pause...maybe it just happens less?

So Iam really only left with ROM to blame.

If anyone else running Shedrock.1.7.0.0.BQA2 could simply plugin their headphones, play the music and wait 5-10 minutes.

Would be awesome to know if Iam the only one with this issue or not.

I got completely clean install of the ROM and I had this issue even before clean install probably since I updated to Shedrock.1.7.0.0.BQA2

I did install Viper btw, but I didnt even touch it, but Iam pretty sure I already tryed reinstalling this version of rom without VIPER.

Dont wanna distract you from kernel, only making a report here and narrowing the issue :D
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Stricted:
make an logcat when the issue occurs, that might be more helpfull
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:
do u have greenify or something? it was my problem, after screen off no wifi

a small app "wakelock" did the job
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Neoony:
Hmmm. I enabled things like "apps that can appear on top and also given permissions to change system settings for many of my apps along with poweramp (totally forgot to do that).

But also I installed some wakelock app and enabled partial_wake_lock in it, but my phone just restarted. It still shows that its checked, but it also shows "no lock aquired".

But no music pause so far.

But not sure which one did it. But I think mainly giving permission to change system settings (settings - aplications - application manager - change system settings)

So thanks so far :P

If it happens again I will report :P
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
Happy you succeed to resolve your problem.

Sorry for not being here but i am workin' on kernel at hospital.

I have now to debug all the new implementations on the source (i will stop here all adds and now debug before releasing a public beta). So do not expect new kernel version soon.

Reminder: latest changes are here (github)
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Neoony:
Gotta say I had a random restart after it working np for 4 hours. So I disabled that wakelock which I enabled in wakelock app (which I think wasnt working anyways) and unistalled that app.

And everything ok so far.

Hopefully for good xD

Hi guys!

I read about last 50 pages of discussions, and really appreciate your efforts in, finally, bring us some fresh meat for this unlucky device!

But I don't have some things clear about the new fantastic kernel I see here...

- First: I have a (even more unlucky) SM-G903M, OEM unlocked, rooted, TWRP-ed, Xposed-ed (!); will ignore it's not a -F or I can't enjoy new stuff you do for -F (is it the same hardware AFAYN?)?

- Can I flash Shedkerneo Kernel (V4 now) on my -W or I'll brick it for sure? If yes, there's something to do before, for ex flash some sam rom (can I flash a -F sam rom on -W model?)

- Will restoring system backup of my stock ROM (G903MUBU1BPF1) reinstall also stock kernel?

Thanks for answering (i guess more others have some questions like these)!

An advice ?

Thanks.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
903F & 903W should be compatible. But for M....

Restoring system backup will not restore kernel if not selected. You should make a save apart. Or having a save of the stock boot.img on your sdcard / pc.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] kaodd:
Afaik it,s a latino edition. I would backup everything and just give it a go ? and have the latest firmware

On the pc (just on case)
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Stricted:
try

#include "cpufreq_governor.h"
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
First error disappeared by just copying cpufreq_governor.h file into the linux include folder.

Last 2 errors remains. Found that these functions are defined in acpi-cpufreq.c. But did not manage to correct those errors.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Stricted:
never do that!

if the file to include is in the same directory use an local include which is

#include "file_to_include.h"

if its a global include use

#include <file_to_include.h>

the functions cpufreq_get_global_kobject and cpufreq_put_global_kobject

are not defined anywere (atlest not in the code on github and not in the upstream kernel, see http://lxr.free-electrons.com/ident?v=3.10;i=cpufreq_get_global_kobject )

so the cpufreq_barry_allen.c is clarly not for the 3.10 kernel
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
It is in cpufreq c in fact. Partially.

If it was not defined i should have not define error. Not implicit. Right ?

By the way, I guess you can add a Fast Charge (USB) in your kernel, if you want to... Just giving an idea :D
[Samsung Galaxy S5 Neo Guides, News, & Discussion] Stricted:
dunno, i can only search for it and if it find nothing it finds nothing...

and still dont just copy stuff to include/linux thats pretty bad and should be avoided

just use

#include "cpufreq_governor.h"

as i told earlier

"" just searches in the directory of the c file first

<> directly search in the global include directories

the problem is you theoretical need to go back to 3.10.1 (reverse patching) to apply the direct 3.10.1-3.11.1 patch

and guess what alone the 3.10.60-3.10.61 patch dont apply in reverse mode...

i did a patch between 3.10.105 and 3.11.10 now

alot of files to correct (the most are easy ones) some are really hard

edit:

git remote add upstream git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
git fetch upstream --tags
git merge v3.11.10 > merge.log

will keep conflicting files and mark the confliting places in the files

and write you in merge.log which files are conflicting

thats the way i patched my kernel up to 3.10.105
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
OK thanks for the tips. Very interesting (learnings :))

About governors erros, on most i had to add 2 files with "include": cpufreq_governor.h & kobjects.h

In kernel >=3.10, many functions were implemented in those files.

The last governor i always get problems with, is zzmoove. Currently i am reading ZaneZam github

Either u do that or just extract the boot.img inside of it and flash with twrp recovery.
[Samsung Galaxy S5 Neo Guides, News, & Discussion] WILMANS2M:
Thanks JMek for answering.

Currently the only IO scheduler added is Row. I will enable deadline with some optimize value and add BFQ (maybe a few others like zen, sio but i dunno).

Same for hotplug. But might need more time for those.

Code has to be a lot more optimized too.

Feel free to comment and ofc, report :)

I recommend Kernel toolkit instead of Kernel audiator (may cause random reboots).

Interactive is always default governor (replaces Ondemand which is deprecated).
[Samsung Galaxy S5 Neo Guides, News, & Discussion] BlackSabbath:
Thanks to JMek... and thanks to Wilmans for tip on kernel toolkit... ;)

I flashed boot.img with twrp. All right..

Now I'm testing smartassV2 gov... For now it looks okay..

Just like there are reports that 2.79 works for some people.
