That's because of missing sources from Samsung for Exynos Aggregation Control.

TW has latest device trees, which are encrypted, so they cannot be ported to non Samsung ROMs due to missing binary signs and certificates.

Status of Fire Opal

Hello,

I'm running the latest Lineage 14.1 Nightly on my Galaxy s7 SM-G930F. I am looking for a custom 3rd party AOSP-based kernel which is stable for use as my phone's daily driver.

I'm curious as to the current status of Fire Opal 2.4.2?

On my current Lineage install with it's kernel, I'm having two volume issues, one a media crackle issue that is intermediant, the second is my volume keeps going all over the place sometimes low sometimes high.

I'm wondering if VoLTE and Wifi calling will work with this kernel/rom?

Does init.d support work?

One of the features I'm interested in is the differences, advantages/disadvantages/usage cases for each type of supported IO, CPU, and GPU scheduler/governor?

I'd like to undervolt when idle to improve my battery efficiency.

Lastly, I'd really like to get fast charge capabilities on this phone.

Does Fire Opal support some, most, or all of this?

Any information appreciated.

Thanks.

Dave.

nice kernel.....but my phone heets up very much when gaming
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Cryoera:
Should i use 3.1.0 or 2.4.2 which one is stable and better
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
None of them.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Cryoera:
I give 2.42. a try it is nice until now but have a question with this kernel is fast charge working ?

Thanks for Kernel tho.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
Yes, but this project is abandoned and filled with old bugs solved in newer kernels...
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Cryoera:
thanks for info can you suggest any aosp suitible kernel or i will use this.

New release announcement

I completed a new release with some stuff added:

- overclock and underclock support for both CPU and GPU
- voltage control (see notes in the OP [B][**][/B])
- moved to Uber Toolchain 7.x (aarch64-linux-android-7.x)
- improved recovery installation script

The note i refer to, in short, says that voltage control is implemented but not reachable by the user.

Next steps in this kernel development are complete access to GPU overclock and voltage control, followed by latest Linux patches and eventual requests by the users.

Have a nice day :)
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Mr.R™:
Your a legend mate, I'll be switching to rr and this kernel like now, thank you

Hi!

Is there a way you could introduce sound control stuff to our devices ? Like faux sound or boefla sound or wodoo sound or something like that to tweak analog gain or something similar ?

Thanks man for your work!

Is possible on dual boot? Get error 1

Thanks for the work
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
Are you using multirom or dual boot

If dual boot are you trying to flash "in app" or through recovery on an existing install?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] farovitus:
Tried that method but didin t work....

What you need to do is copy that .img file from zip file and place it in your internal storage /multiboot/( your data slot name, be sure to replace the file and if necessary rename the new file (.img))

Edit: Don t forget to update ramdisk in dbp app after copying new boot.img

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Mr.R™:
Been using this with rr for a couple of days now and it's looking very promising, looking forward to the new features, full magisk support would be great though, I'm assuming the kernel. Is the issue with magisk, correct me if I'm wrong...
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
Magisk is working fine for me I have Magisk hide and also installed Viper4Android through Magisk without errors and I'm using Magisk as root controller

New release announcement

New release uploaded while I finish some stuff. I spent yesterday on the Linux patches but I will have to do some "tricks" to make them work... and it's a long work.

Version 1.2.2

- now using zen as default I/O scheduler
- changed the default frequency range for the CPU
- updated to Linux 3.18.17 (still working to bring the latest patches)
- switched to a custom Makefile optimised for our architecture
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] v0ne:
Thank you. Your amazing :good:
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
I'm on the build for the 27th
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
unless you're doing something very different than I am I'm not sure that this is a correct statement. If you would not mind please install an app like root validator and then attempt to hide that app using magisk hide and see if the app will function properly . in this case it should be not showing root.

But what I think will happen is that you will get a force close of that app. Also magisk hide is not allowing apps like Snapchat or Pokemon go to work. If you try to hide system UI then you will get a boot loop of the ROM.

If I'm wrong then something has changed and that would be a great advancement for our device and AOSP ROMs . Unfortunately I have not been successful in initiating any type of conversation with the developers of these non Samsung ROMs. I believe that it will take the cooperation of them and the developer of magisk to get this to work

---------- Post added at 01:47 PM ---------- Previous post was at 01:43 PM ----------

unless there has something changed in just the last 2 or 3 builds I have the same experience that you do. I think the difference is if you are trying to use magisk hide versus whether you were just trying to use for root. Unfortunately for me certain apps like Snapchat require some of the Hide function in order to work

Strangely enough my additional experience has been that despite multiple post with four or five AOSP ROMs I have never gotten one single comment or reply from any of the Developers about this issue. It's like a scary topic or something
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
Ok sorry about this, I am using Magisk as the root manager and Snapchat works on my phone. Like you said when I block root on an app like root checker it just fc on entry. I hope this clears things up for you
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
Thanks for replying but sadly I seem to be one of the few that are "clear" .... Lol. Maybe developers included. The partial functioning of Magisk is a huge issue for those that need is full functionality.

That said ... Did you do a fresh install and login of Snapchat? It was just yesterday or day before I tried this ROM while using Magisk and could not get Snapchat to login. Kept getting the dreaded can't login try again later .... Which is supposedly sure to root recognition

Granted Android Pay is something we could all live without. And grown adults can go without Pokemon Go. But Snapchat is a deal breaker since all of my teenagers and young adult friends / family use this regularly to communicate
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
Snapchat works for me without Magisk and with. I was just able to login with root enabled and everything on RR
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
Did you install the ROM, set it up, install Snapchat, login, and later install Magisk?

Or did you install Magisk from the beginning? How did you install, just flash , or unroot first?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
I flashed, set up, installed Snapchat/logged in, and then installed Magisk.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
I think that's why / how it worked

I flashed, unroot, flashed Magisk (which doesn't have full functionality for our device) and then tried to setup and login .... No joy
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
Strange, I'm able to logout and login with Magisk
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] robhug:
Can you explain quickly how did you install ? Like which ROM and Gapps or something special for installation ? And did you flash the latest magisk though recovery , or something different ? Thanks :) I hope I could help us ;)
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
I flashed the RR ROM from the 27th and then Dynamic Gapps (latest version) and then downloaded Magisk from playstore and installed it in app and rebooted
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] robhug:
Thanks :good: but I am right if I said that we need to flash the lineage root before in twrp to then grant too access to magisk app in order to make it install magisk?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
I am using Resurrection Remix, it comes with root. No need to flash
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] robhug:
Thanks a lot I will try this

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
Yes it should

---------- Post added at 11:24 AM ---------- Previous post was at 11:23 AM ----------

I am going to try this just as soon as I can get a free minute .... I have never been able to install Magisk "in app" with this device ----- since this is a kernel thread -- at what point did you install this kernel??
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
I am using the Fire Opal 1.2.0 kernel and RR, sadly I realised Magisk hide is not working fully but Magisk is and the modules are and I can use it as root controller and Snapchat also works for me!
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Mr.R™:
Found the issue, set se Linux to permissive and magisk and its mods as well as things like biohazard will work flawlessly :)

It's always the little things you forget lol
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] dylanneve1:
Sorry, how do you set SE Linux status?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
No, actually it's my fault. I should have set the kernel to permissive before.

EDIT: or have implemented the SELinux patches for Magisk
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Sage:
which is the preferred/supported app to change volts and overclock etc with this Kernel? Synapse?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
Kernel Adiutor, for now. Voltage control will be available when I implement Synapse.

Could you maybe look into this when you're free please ?

Sure.

In your opinion which one is better?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
I'm finishing the test round of the new kernel version. I spent a lot of time studying the defconfigs, comparing them to the stock ones and tweaking them.

I also decided to temporarily revert to Linux 3.18.14 as we had a video playback issue (I still want to bring the latest patches).

I'll post the update soon.

Awesome kernel

What rom do you use with this kernel?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
I forced the kernel to Permissive so there shouldn't be any problem.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jcrompton:
Hey man thank you for continuing your work.

Here's what I tried:

Flashed the 2-28 Xenon

Flashed Mini Dynamic Gapps

Flashed your latest kernel (here)

Flashed Magisk 11.1

No errors or problems - yet

Reboot and setup ROM

Immediately knew there may still be an issue because Magisk Manager was not in the drawer (with successful flash of Magisk usually Magisk Manager is inserted in the apps)

Playstore install Magisk Manager

Root is successful

Magisk Manager -/ Settings ,, clicked Hide

No apps are hidden from root

SafetyNet fails after long time spinning

Tried all tricks like (Disable USB DeBugging, set permission 0640 sys/fs/selinux enforce)

The problem is still that Magisk is only partially functioning when it installs (Magisk Hide doesn't work and I suspect not fully installing since Magisk Manager not inserted)

I think it still has to do with the Magisk repacking of the boot image when Magisk gets installed

someone suggested putting the boot image up on github [MENTION=4470081]topjohnwu[/MENTION] uses for Magisk

I only used faux sound previously since my prev phones were Xperia S, Xperia Z1, Xperia Z5P

Guess the end goal would be modifying the analog gain with not increasing distortion.

Actually, most of them break stuff. I tried using his prebuilt toolchain for 1.2.5 and it ended up with messed up drivers. Same thing with his Linux patches. Sadly got a lot of .rej and despite fixing all the code by hand it still ended up in a kernel with some stuff broken.

Apparently Fevax did some deep hacking to make Samsung source work on AOSP.

Flash 2.1.2 ;)
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
New release announcement

Version 2.1.2

- init: added a few tweaks

- ramdisk: changes in sepolicy

- ramdisk: try to fool safetynet and fix wakelocks

- updated to DQBO kernel source

- fstab: reworked mount options

- fs: add exfat support

- fs: implement optimised and stable f2fs (from oneplus/QC8996_N)

- enabled Swap (I had the idea while looking into the OP3 sources)

I'm quite proud and optimistic about my implementation of f2fs in this kernel. At the moment no issues at all, and it's faster (as it should).

Try it out ;)

If you come from an old version and experience these slow downs you should clean flash. I have updated many things and the leftovers of the original kernel/old versions can sometimes bring up problems.

[MENTION=5645637]kylothow[/MENTION] I love your work! I am currently using your latest kernel on LineageOS 03/07 build and it is flawless. I just had a question since I'm pretty new to some of the kernel features. How does f2fs work? What do I need to do to set my phone or the ROM I believe in f2fs partition? I really want to try this out. :D
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
Just reflash the ROM. Creating a zip that restores stock kernel would be complicated because of all the different ROMs and the fact they're updated every day.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Mongobill:
I have flash the rom and your kernel 2 times after a.clean install.no chance.many lags and very slow

Gesendet von meinem SM-G935F mit Tapatalk
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] kylothow:
First you have to install a compatible recovery. You have to look for the 3.0.2-5 by Tkkg1994 that supports f2fs mounting.

Then you have to backup all your data (internal storage too will be wiped).

After this, from advanced format select /data, and then change filesystem to f2fs. Do the same for /cache.

At the moment I don't think there are ROMs that support f2fs on /system too (LineageOS forces ext4).

After this you're done. Flash ROM, kernel, GApps and what you want then reboot and enjoy the only filesystem with a decent random write speed [emoji23]
