[ALL][Kernel][9.0][EAS][AOSP] Tachyon Kernel

What is a Tachyon?
Wikipedia calls it a "hypothetical" particle that most scientists claim doesn't exist.
That is what this kernel is: A kernel for Treble, something Motorola claims they never will release for our device.
Why upstream?
Well, DirtyUnicorns put it best on G+ : https://plus.google.com/+DirtyUnicornsOfficial/posts/2MpHCwKqh5J
This kernel will stay updated to the latest upstream from Linux-stable tree maintained by @nathanchance on git for msm
What is EAS?
Energy Aware Scheduler is a scheduler that knows how much energy is used on each frequency and how much power it uses to give best power/performance ratio. This kernel is slowly getting updated to the latest EAS patches from Linaro.org. For more information, check the below link.
https://www.linaro.org/blog/energy-aware-scheduling-eas-project/
Features:
Upstream kernel from source
Edits to avoid Safetynet/CTS (If you have root, it will fail signature check inherently without SUhide or Magisk hide)
Built With the Latest Clang for Android with Linaro as the cross compiler
OC GPU (changed 710 MHz to 750 MHz)
Same Adrenoboost tweaks as the Pixel 2 ElementalX kernel.
Wakelock fixes by Boeffla
EAS implementation (still work in progress)
Bugs/Issues:
hit and miss on MotoMods
Download:
Google Drive
Instructions:
Download ZIP to phone
Boot to TWRP.
Flash and follow prompts in Aroma
If you need to flash any GSI zips to boot your GSI, flash them again.
Reflash root if you want root.

A note about donations
Quite a few people have asked to donate to me in the past and I have turned them down. I am not in this for the money, this is my hobby, something I truly enjoy. If you truly want to donate to something (it is not expected in the slightest), I recommend an entity like the Open Source Initiative, the Free Software Foundation, XDA, or any one of the people I have thanked in the OP. Additionally, you are free to copy any and all of my work; the only thing I request is that you not ask for donations as well (though I can't really enforce this lol). Thank you.

Changelog:
08/14/2018:
Initial release
02/06/2019:
Rebase for Pie

EAS Progress:
Schedutil is a form of EAS. I am currently working on fixing it to get it more in line with how smooth EAS runs on the Pixel. (yes, that means Energy Aware has always been in the AOSP kernels, we just never talked about it. Now that I am updating it to the lastest from Linaro, I am being open about it).

Known issues: GSIs don't work.

Hey there Uzephi. This is for the latest 8/14 build of lineage, right? Because after flashing, I'm stuck on the lineage splash screen.

Apparently the Tamien vibrator changes haven't been merged yet and are still in Gerrit. I am reverting and will release the fixed kernel in about half an hour.

Updated. same Download link, will now work with Lineage Official that released today. (old build worked on test-keys on 0808)

It's only for Treble. The kernel mounts vendor, so even DU won't boot it.

4.4.148 updated, pushed, and uploaded to Drive. No other changes

sorry for my stupidity, but which roms are actually compatible with this kernel?

Any ROM built for the Z2 force that is treble enabled. Currently running into a no boot with GSI images and working on fixing that. Currently I think that's only Lineage officials built after 08/14. I don't know if DU has gone treble yet.

link updated to 4.4.150. added back CRC as well. Still no verification if that fixed GSI boot issues

anyone else have screen flip recovery issues after flashing this? everytime my recov screen does a 180 no matter if its twrp, lineage rec, etc

Its a known issue. Stock lineage kernel does this as well. Best thing to do is just boot twrp.
Edit: 4.4.152 merged and Gdrive updated.

4.4.153 has no changes for us. I merged just to be in line with linux-stable but not releasing a build.

I've only had this issue with this kernel, every other kernel I've tried stock or custom have all been able to load twrp correctly. For some reason though I haven't been able to flash any ROMs with the newest twrp, I always have to use 3.2.2.1 official or the 3.2.2.1 for treble.

Updated to 4.4.154. If you are having issues with TWRP, try flashing the installer after the kernel, I haven't had an issue doing it this way.

will this work with Lineage Unofficial builds??

Hi! Great new kernel I just want to report that double tap to wake isn't working when I flash this on PE+ rom (oldcam rom). I know that it is maybe due to the fact that oldcam is not supported but can we expect to atleast get the d2tw working

will try it for next build.

I installed rain kernel on PE+, no issue so far. for oldcam ROMs, just flash newcamblobs.zip.
but when first install the kernel, it's aborting, say there no ramdisk to unpack. need magisk installed before to get kernel installed. thank you.
edit: seems led is not working on ROM that not based on los tree.

*** Be aware, there may be a need to wipe data if you desire to go back to stock kernel, my suggestion is to backup your stock BOOT partition and DATA before flashing. This way you can return to your original setup easily. It is unknown at this stage what data is causing an issue going back to stock. If you find it, be sure to share.
* You must have bootloader unlocked and rooted your device with Magisk before flashing this kernel. Magisk is essential for camera and wacom.
* Boot times are approx 60-75sec at the moment, itll sit on the yellow triangle splash for approx 60sec and the bootanimation for 5sec.
* When flashing this kernel, an AnyKernel helper module is installed. This is a Magisk Module that is essential for the operation of Camera and Wacom. Removal of this module while running this kernel will break camera and spen.
* Kernel zip labels have either a P or E in them, P=Fully Permissive, E=Enforcing (switchable)
To install
download and flash the kernel installer zip in TWRP or any custom recovery

Amazing to see some development, i thought this phone thread was gonna be dev dead

I am a little surprised myself.

Status update
I have found a couple of bugs I'm working on, #1 camera module only loads on permissive version of kernel, #2 the flash doesn't work, #3 random reboots maybe 4-5 times a day.
Working on having a stable R2 this week.
Edit: so it seems the hourly bootloop happens on stock kernel for me also. So it isn't an issue with this kernel. Though I do need to fix the flash

WETA Kernel R2
Upstreamed to 5.4.118
Fixed Torch/Flash
--->

WETA Kernel R3
Starting from scratch with different source code. It seemed there were problems booting for most. The new test kernels have been successful.
This is a basic start, with the intention of upstreaming and testing along the way.
--->

WETA Kernel R4
Upstreamed to 5.4.119
* Testing was successful with the different source code kernel
* Remember you MUST have magisk installed Pryor to flashing this kernel, this kernel needs it's ak3-helper magisk module for camera operation.

I have used your Kernels in the past for other devices, really loved them. Was wondering if you plan to make a custom kernel for the s21 ultra Exynos in the future ?

Excuse my ignorance but please elaborate on "knox disabled"? I have unlocked bootloader/magisk and knox is already disabled as far as I know. Would this mod to the kernel allow me to use knox locked features that have been lost, eg biometric security for some apps? Thank you for your work, look forward to trying it out

Kernel based Knox ncm is disabled, it has nothing to do with your "Knox fuse" which is blown when your bootloader is unlocked.

I don't plan on building anything for devices I don't hold in my hand. Reliable testing is hard otherwise

Just a note regarding boot times, I can achieve a 35sec boot time, though in doing so it breaks double tap to wake, and fingerprints. I won't release a version with those broken items.

Wireguard kernel module support?

I'm looking for an A13 ROM or Kernel for this device which has wireguard kernel module support baked in. AFAIK the last one I'd used was the fsociety tribute kernel for A12 but have since moved on. I feel like there has to be something? I was looking in to building the kernel from source and adding it in myself - but I currently don't have the hardware to achieve this task. Any help would be super.

Disregard unless you want to share your preferred option. Found Sleepy Kernel via the fsociety telegram channel. Works like a charm!

Wow, nice job!!! thanks you , bro !

Some noob questions as I'm very new to this whole KernelSU thing:
- Will this work with LMODroid 3.3? The ROM is similar to LOS19.1 in functionality, and is using the same kernel and device trees.
- As both LOS and LMODroid (which I'm using) are still being actively updated via OTA, will OTA continue to work when using your KernelSU? (NB: Magisk can survive OTA if installed correctly)
- I wonder how much will it be able to conceal root from certain apps... Right now I'm using official Magisk with Shamiko to evade detection, which is adequate for now. How could I achieve similar functionality with KernelSU?

Thanks for reply !
1.It can work properly on some os based on LineageOS(19.1)
2.OTA will still continue to work but you will have to flash this kernel after OTA (MayBe you can write a addon.d script to auto flash it after OTA)
3.If you don't use zygote hook(zygisk/riru) modules , it is unnecessary to flash shamiko(can work on KernelSU)
PS: use the latest build may be better?
