[Samsung Galaxy S8 & S8+ Cross Device Development] ayyyy lmao:
This kernel undervolts, I'm not sure if the phone can reach that frequency with an undervolt. Although if it does, I'd like to have it as well ??
[Samsung Galaxy S8 & S8+ Cross Device Development] gzdc:
i hope this more overclock that another guy asked for, it s nice to have the option to do more
[Samsung Galaxy S8 & S8+ Cross Device Development] CHiBLaST:
Cant wait for new version. I installed MTweaks but i cant find voltage controls. I want to undervolt my CPU so more battery saving.

Isnt 2.81 GHz overkill? Honkai Impact 3 runs really smooth with 546 MHZ GPU and 2.6 GHz CPU. If its for benchmark yeah it ll score higher :S
[Samsung Galaxy S8 & S8+ Cross Device Development] ubelai:
Any news? :silly:
[Samsung Galaxy S8 & S8+ Cross Device Development] mikechedvey:

How is it going? Are you testing it?
[Samsung Galaxy S8 & S8+ Cross Device Development] artaniss11k:
[MENTION=7291478]kdrag0n[/MENTION]

Did you tried to undervolt with -25mv? On my previous devices (s4, s5, s6 and s7) i even went with -50mv with stock frequencyes ( no over the stock limit frequencyes ).
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
I guess so, but more optional performance never hurts.

The next release is coming soon. I've been busy with my new Pixel 3 kernel recently. There's optimizations from the Pixel 3 and more imminent in the release :) Just need to figure out some reports of major stuttering.

It's supposedly already undervolted by 100 mV, although I've found out that it's placebo and not actually undervolting anything because I tried undervolting by 1 volt and everything still worked fine.

[MENTION=7291478]kdrag0n[/MENTION] someone on ambassidii kernel telegram group told that flickerfree option shortens the display lifetime. He said if you want to burn your screen use it. I couldnt find any info. about it. Is it really true?

I am asking u since u have that in your kernel and you had the possibility to check the code.
[Samsung Galaxy S8 & S8+ Cross Device Development] xdausr123:
I tried it out but afwall still can't log. thanks anyway.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
AFWall logging is probably IPTables logging. That's been disabled.
[Samsung Galaxy S8 & S8+ Cross Device Development] Near_07:
Patiently waiting for the update . . The only problem i face was stuttering issue and lags after 3-4 days straight use. .need to reflash the kernel again to refresh the system

Did you ever make progress on this?
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
uhm.. [MENTION=7291478]kdrag0n[/MENTION] did u abandon this kernel mate?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
No.

No, I just haven't gotten around to doing a stable release on XDA. It should happen as soon as I update Magisk to 18.0.

It'll be worth the wait, testers on Telegram have said the latest version offers some of the best battery life they've had since they bought the device. Performance is better as well.
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
Happy to hear mate! Hope to try out soon :)
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
Great to hear that you didn't gave up on this great device.

Also, will we get 2.8 oc?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
No, it wasn't working. Maybe in a future release.

[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Yes. If I make a change, it'll be in the changelog.
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
It says clear that is crk1 based.
[Samsung Galaxy S8 & S8+ Cross Device Development] roizcorp2:
it means when and if CRL3 based kernel will be delivered?

wise@$$
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
Simple, don't ask for future updates. Devs are human too, and they do this for fun in their free time. Just wait until he decides to update the base, but I don't think we'll se crl3 base, but the next one. Base in kernel doesn't matter, you can run the latest firmware with an old kernel base.
[Samsung Galaxy S8 & S8+ Cross Device Development] CHiBLaST:
It stucks at "please choose a SELinux mode" It does nothing when I press volume up or down. I have tried to install both Lightrom Nougat and Alexis Rom 7.1 Pie maybe thats why. I ll update when I ll install it to Lightrom Oreo. Also Lightrom Pie too. I can install this kernel to Lightrom Oreo.

[MENTION=7291478]kdrag0n[/MENTION] Dude your latest release has a real lag problem. I tried everything but when I start a heavy task (like pubg or even chrome) the phone freezes completely. Cant do anything, have to restart afterwards. Dont know what the problem is.

I am on latest rice rom.

Lets hope [MENTION=7291478]kdrag0n[/MENTION] gives us some of Pixel 3 XL love too :)
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
As I'm sure you've all seen, updates for this kernel have been slowing down recently. This is because I've moved onto the Pixel 3 XL as my primary device. The experience is just miles ahead of the S8 in nearly all aspects, leading me to basically ditch the S8 entirely. Instead of making do with unstable updates with several months between each update, I've decided to just abandon all development for this device. I may still push commits from time to time on GitHub for personal use, but there will never be another public release.

It's been a great journey and learning experience along the way as the second kernel I've ever worked on, but I'm afraid it has to come to an end like all good things do eventually. For your next kernel, I'd suggest trying out RZ Kernel which seems to be quite promising so far with the first EAS implementation for our device. Sorry for any inconveniences this may have caused.

You can still donate to support my future projects and other endeavors if you wish.

Farewell.
[Samsung Galaxy S8 & S8+ Cross Device Development] kyzn:
Just FYI. You should never do that. It's better to dirty flash your ROM to get rid of the custom kernel before switching to another. A custom kernel must not be flashed over another custom kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] mrjoy:
Wi-Fi on/off problem. Unable to on wifi
[Samsung Galaxy S8 & S8+ Cross Device Development] blasen01:
That is complete right! Or we need a cleanup script for the next flash.

I heavy debloat my S8 that's the reason why I don't won't to reflash that ****.

Wifi and VoLTE dont work
[Samsung Galaxy S8 & S8+ Cross Device Development] Alexior:
damn this kernel has an incredible potential... I hope that the dev will fix these bugs!
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
I'm not sure how everyone is getting lag. Figured out how to fix Wi-Fi though. Could everyone with lag post their custom kernel settings and what kernel they came from?

Telegram group incoming.

Charging LED works fine for me on Ambasadii, just pulsing instead of solid.
[Samsung Galaxy S8 & S8+ Cross Device Development] kyzn:
That wouldn't stop you from flashing boot.img to get stock kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] thiagomed:
Works fine for me. LightROM S9 Ported ROM with MadMax ADV. Any app to control those features?

What about Dex with any HDMI adapter. Anybody has tested? How it works?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
A workaround for bootloops (especially coming from NX) is to flash MadMax Advanced or TGPKernel first, boot once, then flash Velocity. Sorry for the inconvenience, r3 will fix this.

You can try the latest pinned beta from Telegram which fixes it as well.
[Samsung Galaxy S8 & S8+ Cross Device Development] xrjr1016:
After flashing this kernel,I lost all my data when I rebot my phone.I just try flash my phone with ODIN ,but it doesn't work. Now I can't wipe data/system( Invalid argument).

Please help me!
[Samsung Galaxy S8 & S8+ Cross Device Development] thiagomed:
I've installed and works for me, but it's very very laggy. So I went back to MadMax ADV
[Samsung Galaxy S8 & S8+ Cross Device Development] Mangtas_666:
Same here very laggy with Ambasadi Rom
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
I just released r3 which fixes Wi-Fi, bootloops, and low amount of apps staying in memory. Get it here on GitHub.

I don't experience any lag myself on Ambasadii or GoogleWiz ROMs. To fix the issue, I'll need anyone who experiences lag to run the following command inside a root shell/terminal (su):

logcat -m 1000 '*:E' > /sdcard/settingslag.log

To be of further assistance, run this command as well:

echo 1 > /sys/kernel/printk*/*

Now use the device for 10-30 seconds, triggering lag (and Settings crashing if you have that). Then, run this command:

dmesg > /sdcard/klag.log

After running the commands, send me settingslag.log and/or klag.log from Internal storage/internal SD card. You can do this over Telegram, XDA PM, or posting in this thread. Thanks!

By the way, the new CRED source is capable to be compiled with google's clang compiler but im lacking the skill to debug whats happening since it doesnt boot and doesnt produce any logs, for a moment i've been gathering parts to build a uart ftdi cable to debug this directly after booting. Do you want to work together with me to accomplish this?

---------- Post added at 12:42 PM ---------- Previous post was at 12:19 PM ----------

Also, wake gestures isnt working. Want me to get you logs? Or you already know this?

---------- Post added at 01:08 PM ---------- Previous post was at 12:42 PM ----------

And it seems that you use linaro 7.3 on your clang build script. Have you acknowledged that the vanilla toolchain provided by Linaro will cause the system to reboot randomly and turning the cpu big cluster offline sometimes?
[Samsung Galaxy S8 & S8+ Cross Device Development] Noxxxious:
You must be using a S8+..
[Samsung Galaxy S8 & S8+ Cross Device Development] chinhtao:
someone tried this kernel, wanna see feedback, my zalo app crashs when im using this kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Sure, it'd be great if you actually got UART during boot working.

I'll look into the wake gestures issue, it seems to be exclusive to Samsung touchscreens (most regular S8 models).

I didn't know Linaro might've caused rebooting, I thought it was GCC 7 as a whole. I'll try another toolchain.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:

some how this is misbehaving with the rom from sac23

but new build is awsome and kernels now install

dragon we can test some more m8 when u ready as it isnt a rom issue now i think

[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Any app you want... I like EX Kernel Manager and MTweaks.

There are also pre-tuned profiles (Balanced, Performance, Battery, Gaming) available via the Spectrum app, or Spectrum tab in MTweaks. I strongly recommend using these.
[Samsung Galaxy S8 & S8+ Cross Device Development] reaper000:
Thanks for the kernel!

I configured sweep2sleep in EX Kernel Manager to sweep right but it doesn't appear to work.

Oh, and any chance that you might consider adding doubletap2sleep in forthcoming versions?

Having another kernel option is much appreciated, regardless.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Yeah, only up and down are supported by the driver.

I don't see how double tap to sleep would work. Never seen that done before, and it'd trigger all the time.
[Samsung Galaxy S8 & S8+ Cross Device Development] reaper000:
Thanks for the quick response!

When implemented, DT2S is typically confined only to the status bar. It's a feature included in some current ROMs (such as Renovate) but it was a feature in kernels of past phones, like flar02's Elemental X for the HTC One. Just thought I'd ask, no biggie

[Samsung Galaxy S8 & S8+ Cross Device Development] eliaferri:
I tried f2fs, but it doesn't boot

what's the correct procedure?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
You can't use custom kernels with encrypted data. If you want encryption, stay on stock kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
In TWRP switch filesystem to f2fs. It requires the ROM to support it as well. I'm not sure which ones do.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
It's still possible, just happens less. Turn off LED fade ramp control in MTweaks LED panel to fix it.

Am sorry how am i even encrypted my data partition got corrupted one time after i rooted my phone and i needed to reformat everything and i installed a custom rom after the format not a stock one, and i also can install TGP AND NX but only this one bootloops, if you dont mind can you tell how do i decrypt my data?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Flashing the kernel and tapping Format Data in TWRP -> Wipe should do it.

I'm not sure why TGP and NX work for you.
