[PIE][Kernel][28.11.2020][4.9.246] Kirisakura_NEXT 1.2.0 for HTC U12+ aka Imagine - HTC U12+ ROMs, Kernels, Recoveries, & Other Develo

Kirisakura-Kernel for HTC U12+
Hello everyone,
Kirisakura kernel is designed to bring a handful of beneficial features to the device, while ensuring excellent performance and smoothness to get you safely through the day!
This includes upstreaming to latest linux stable for enhanced security and stability. As well as bringing in important new CAF patches, as soon as CAF releases the sources for the SD 845!
Revisiting the stock EAS implementation for further efficiency enhancements is also on my current roadmap for future development. I´m sure there is potential!
To have a read about our scheduler, which is called EAS, take a look here:
https://developer.arm.com/open-source/energy-aware-scheduling
Main Features:
- Based on latest kernel sources from HTC for the HTC U12+ (2.45)
- Upstreamed to latest 4.9.246
- CAF-Upstream merged
- Pixel 3/XL EAS ported over
- Cleanslate features from @tbalden included! (big thanks to him!)
CPU related features:

Feature section for the "non visible" but perceptible improvements:
- mark certain IRQ and kthreads as performance critical
- updated schedutil governor
- updated binder section (responsible for interprocess communication)
- updated sdcardfs (have a read about it here: https://www.xda-developers.com/divi...les-fuse-replacement-will-reduce-io-overhead/ )

- Memory allocation overflow protection (kernel hardening feature)
- proc gate vulnerability fixed
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries

How to flash the Kernel:
1. Download the kernel.zip to your device
2. Reboot to TWRP
3. Flash the kernel.zip in TWRP
4. The kernel zip will detect if you´re rooted and keep root in that case!
5. Reboot and Profit
IMPORTANT NOTICES
1. After rooting, the option to enable face unlock from htc may be greyed out.
How to fix:
a. Open Magisk Manager
b. Open the side menu and tap on magisk hide
c. Tick faceunlock to be hidden
DOWNLOAD:
Download is located always in this folder:

How to set up the kernel
as with release 4.1.1 it’s advised to change no boost settings at all! It’s all flash and forget
This is a short guide on how to set up the kernel. This is currently required because TWRP is not yet ready and therefore I have no ak2 zip to set that all up.
The following is deprecated as with 0.5 Release!
Basically I decided to disable pnpmgr. This is htc’s daemon for controlling the CPU boosts.
I integrated a few other boosts to the kernel that work way better to replace HTC´s mechanism.
The phone is more smooth and more efficient now.
This is not a requirement at all. It´s entirely optional in case you aren´t satisfied with the current state of things!
1. With a root explorer go to /system/vendor/etc and rename pnp.xml to pnp.xml.bak
That will disable pnpmgr on the next reboot.
2. In EXKM navigate to CPU -> Boost Settings
3. Set the values like on the attached screenshot! and toogle the arrows to set it on reboot
4. cpu input boost currently has no interface in EXKM. The predefined values are fine. But if you navigate to Tools -> User Settings, you can call any file and change the values exactly to your liking.
Just hit the + and add the following paths:
sys/module/cpu_input_boost/parameters/input_boost_freq_lp boost freq of the little cluster
sys/module/cpu_input_boost/parameters/input_boost_freq_hp boost freq of the big cluster
sys/module/cpu_input_boost/parameters/input_boost_duration boost freq duration
5. Reboot and profit
The following is advised as with the Release of 0.5!
1. If you previously renamed pnp.xml found in /system/vendor/etc, to pnp.xml.bak, rename it back to pnp.xml!
Now reboot!
2. Here is a screenshot of the optional boost settings I´m currently running. These are a bit more aggressive than stock, provide more smoothness but cost a tiny bit of battery. In the end I still achieve way better battery results on 0.5 than on 0.2 even with additional boosts enabled. That is due to the energy saving commits I mentioned in the changelog of 0.5.
Here is the screenshot!

You can control kcal with exkm app.
But you can just control srg, saturation, contrast etc.
With Kcal nothing can be done about the brightness. Sorry for that!

I forgot to add Wireguard as a supported feature. I corrected this in the OP.

There is absolutely nothing wrong with the brightest on this phone. Slightly dimmer than U11. Currently have auto brightness off and set just under half way. In the sun it visible at 3/4 brightness.

Just did a side by side pic and to me the U12+ seems brighter probably due ether cooler color.
