Kirisakura-Kernel for the Rog Phone 3

Hello everyone,

To keep it short: Here is Kirisakura - Kernel for the Rog Phone 3 aka OBIWAN.
I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.

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 project aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security and performance, while keeping stability as the foucs during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.
Kernel Control Flow Integrity (Kernel-CFI), which is achieved by linking the kernel with LLD and Link Time Optimization (LTO), more precisely ThinLTO, are quite unique security features. In fact this, alongside Kirisakura-Kernel for the OnePlus 8 Pro, may be (and probably is) the first 4.19 msm kernel with a fully working Kernel-CFI implementation and CFI-Violations fixed on a smartphone.
The only kernels made by OEMs offering this security feature are the ones for the Pixel 3 and Pixel 4 devices.
The recently released Kirisakura-Kernel for the OnePlus 8 Pro was featured on the XDA-Portal due to the inclusion of CFI. The featured article explains CFI in great details, is easy to understand and definitely worth to read.

Another security feature is Shadow Call Stack (SCS). Similar to CFI, only the Pixle 3 and 4 Kernel use this security feature.
SCS is another security patchset that is aimed at preventing attacks via return oriented programming (ROP).
ROP is a technique where the attacker gains control of the kernel stack to overwrite function return addresses and redirect execution to carefully selected parts of existing kernel code.
If you´re interested here are a few good links:
Google Security Blog explaining SCS.
LLVM doc about SCS
Android DOCs documenting SCS

If reading about upstream in the paragraph above got you curious,have a read about Linux-Stable and why it is important here. The stable-process is not the same for every subsystem, but the general idea, rule of thumb and benefits are applicable for other subsystems as well.

Quick explanation of CAF-Upstream. CAF is short for Codeaurora-Forums. This is the place where development from Qualcomm for their SoCs happens. This includes the Snapdragon 865/+ that´s built into the different SKUs of the Rog Phone 3.
The kernel-bases available on the Codeaurora-Forums, are basically the foundations OEMs use, to build their own kernel additions on top for devices featuring Qualcomm SoCs.
The Qualcomm developers push regular updates to the bases of the different SoCs, a bit similar to how Linux-Upstream works. OEMs usually stop updating the initial base after the phone is released.
This kernel focuses amongst the other features to provide the latest CAF-Updates merged in a regular manner, to provide updates, improvements and enhancements for SoC specific drivers and subsystems! This might take a while, because a lot of device specific testing is done on my end to ensure stability.

The kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
I´d like to mention @tbalden ´s excellent CleanSlate features at this place. They improve usability by a big margin for me personally. The highly customizable sweep to sleep implementation (adjustable to different navigation settings), long tap to bring down status bar (very useful on a big device), backlight dimmer and notification reminder are very useful features that I use personally every day.
Another big part of improvements originate from @arter97´s, @kdrag0n´s and @Sultanxda´s work. Many others contributed in some way or another to this kernel.
A big thanks to all of them at this place!

Now lets continue with a list of features in the next paragraph!

Requirements

- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- magisk root


How to flash the Kernel:

1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Asus Stock-Firmware. When the Rog 3 receives an update it takes Asus a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
Always make sure to run the firmware the kernel is built for!

1a. Optional: While it may not be necessary all times, you may want to restore stock boot.img, re-root with magisk and optionally install twrp.zip if coming from another kernel. Before reporting issues make sure you do that! Thank you!

2. Make sure to use at least Magisk 21.0. , otherwise your phone won´t boot due to Selinux-Mainline being present in the kernel. If you´re one of those that can´t use magisk 21.0 or greater on stock kernel, update to beta/canary channel in magisk manager settings, update magisk to 21.0 or greater via magisk manager, do not do a full reboot instead proceed to step 3 without a full reboot!

3. Flash the kernel.zip via latest EXKM or FKM app, or TWRP (haven´t tested TWRP myself as I don´t need it) and do a full reboot.

4. Reboot and profit.

FAQ

F.A.Q:

Question:
Why does the kernel version show as "unavailable" in settings after flashing it.
Answer: Asus does not allow for custom kernel names in their settings. Use a kernel manager to check the kernel version.

Question: Is root preserved when flashing this kernel?
Answer: Yes, the AnyKernel.zip will detect root and keep it.

Question: How do I return back to stock or another kernel.
Answer: Extract boot.img as well as dtbo.img from matching firmware you are on and flash the extracted boot.img and dtbo.img via fastboot. If you want to keep root flash back the magisk_patched_boot.img. Or dirty flash your rom.

Question: Why is having Magisk installed mandatory for this kernel?
Answer: Android 10s changes to partitions, doesn´t allow files in system/ and vendor/ to be replaced. This kernel is very far from the stock kernel. To account for this I can´t force load the stock kernel-modules for certain drivers as it happens on kernels that are closer to stock.
Instead we use Magisks function to overlay certain files during boot. Without a working Magisk environment the kernel cannot function.

Question: I have a phone that is converted from CN to WW and now there´s a warning from hardwarestub. Can I hide it?
Answer: Yes, I created a Magisk Module for those that want to hide the notification, so nobody needs to rely on paid apps.
The Magisk module can be found attached to this post.
Please note that refresh rate can´t be changed when the module is flashed. To able to change refresh rate or to remove the module, simple remove it in Magisk Manager and do a full reboot. I´ll attach it to the third post on this thread. There will be no support for this module from my side and no other support for converted devices.

Question: How to report bugs properly?
Answer: Have a look at post #3 in the linked thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re running on a stock configuration. That´s means you´re not using any mods, tweaks in kernel managers or other root tweaks , magisk modules, scripts or other modifications that alter various functions like sound mods, data traffic, sleeping behaviour, scheduler, magical battery tweaks etc.
Try to describe the issue as detailed as possible! Give your exact setup, like rom, magisk version, kernel version.
Is the issue reproducible? Does it happen frequently?
Provide logs, otherwise debugging is a lot harder. If you can already reproduce the issue and provide logs it greatly limits the amount of time I have to spent until I figure out how to reproduce it.

If the device force reboots/randomly reboots (that means you see the bootloader unlocked screen!) provide a .zip of /asdf.
Easiest way is immediately after booting up, with a root explorer navigate to /asdf. Copy the contents to your internal storage, zip it up and send it to me.

If the issue happens while the device is running provide a dmesg plus a logcat that you take while/shortly after the issue happens. This will log what´s running in the current session. Try to be as detailed as possible what´s happening when the issue appears. It will also help me in reading the log!

CleanSlate Features and how to use them

CleanSlate Features and how to use them


This kernels offers its users the possibility to use CleanSlate features. CleanSlate-Kernel is developed by @tbalden.
CleanSlate kernel follows a different approach than Kirisakura-Kernel.
We know each other well over the years now and often have worked together.
For more information about CleanSlate visit @tbaldens CleanSlate thread on the Rog 3 Forums linked here.

The CleanSlate features add a lot of flexibility to a device. That´s why I like to include the features in my kernel.
Notifications Reminder, Flashlight Notifications, Turn Phone to sleep and a very advanced sweep to sleep interface that works well with Android 10 Gestures.
We decided to transform Brightness Dimmer and FPS-Override into CleanSlate accessible features as well.
That allows users to easily control these features with the CleanSlate apps.

CleanSlate features are easily accessible via the CleanSlate Configuration app. The Cleanslate Companion app provides a userspace backend for the kernel and is required for some features.
Make sure to install both of these apps, when flashing my kernel and you want to utilize these features.
The apps ask for some permissions. Enable them and do a full reboot to make sure everything is playing nicely :)

that´s how the companion app will look after enabling it.
https://photos.app.goo.gl/x6sFJc5cUFT9Q7U47
It´s needed for userspace related features, like double tap swipe area for notification pull down.


Every section of the Configuration App has different settings. Basic, Advanced and Preset. You can click on these buttons to change between them.
Advanced will offer you more customization if available.
See the screenshots here:
https://photos.app.goo.gl/avPsiHHrzPwpMqMC8

To change settings, change them according to your liking and hit the "Save" Button. It is the second from the bottom right and will be greyed out if your settings are currently applied.

As you can see in the following screenshot:
https://photos.app.goo.gl/qaFKfLbfwUuyHW717
Brightness Dimmer is enabled, FPS override is set to 144FPS on low brightness. Power button is blocked in pocket and screen gets disabled when putting the phone face down on a desk.


You should be able to find both apps for free on the CleanSlate thread. However if you benefit from the features, think about getting the premium apps on the playstore to give a little bit back to @tbalden.

I hope this post might help some :)

just a small heads up before anybody complains. :D
We, @tbalden and me, just noticed a bug went unnoticed during our previous testing.

If you flashed this kernel or CleanSlate-Kernel, have the CleanSlate config app installed and Backlight dimmer enabled in the CleanSlate Config app. Make sure to keep the screen on for 3-4 minutes after rebooting your phone and the boot process finished.
Otherwise your screen will stay black. Display-Panel driver doesn´t seem to like our mod at the moment.
After keeping the screen on for 3-4 minutes the bug will not be triggered and you can use the phone as you wish.

Sorry for the inconvenience ;)
The issue will soon be resolved in a new update :)

Also just start the app manually on reboot, as a workaround.

Coming here from your OG Pixel kernel. Is this kernel for 2007.47 or 2007.32?

Nice to see you made the jump! Must be a hell of an upgrade on your side!
the .47 sources are merged. I´m using it on .47 at the moment.
I guess you can just give it a try and check if it boots/works on .32. :) If you decide to do so, it would be nice if you could report back here. It might help others :)
Make sure to have a PC with working fastboot environment nearby and a boot.img handy.
In case it doesn´t work, just force the phone to power down by holding power button plus volume down, once it powers off, keep holding power and volume up to boot to bootloader.
Connect to side port and flash your backup boot.img via fastboot. Always make sure to flash the matching boot.img for your firmware. :)

Hey guys and girls,

Here´s the fix that solves the black screen issue, that occurred when the screen was off while Brightness Dimmer got activated via CleanSlate Config App on boot.
It wasn´t detected immediately, because usually the screen of my device is on when I boot the phone as to check the logs and ensure everything is working :)

Now everything is working, so just flash the kernel and enjoy ;) I´ll do a post soon, explaining the features a bit more for people unfamiliar with how the CleanSlate features work.


I´d advise everybody to read the instructions in the OP and follow them. They are written for a reason, because they ensure everything will be working as expected.
Kernel is made for the latest stock rom from Asus, you must update your phone to the most recent Asus update, before flashing the kernel.

Enjoy!


Changelog:

- Fix Screen not being able to wake up on a certain condition.

I wish you all a nice day/evening!


Download is below :)

Instructions how to flash the kernel can be found in the OP!
But look at this post too :)

To make use of the CleanSlate features, like force FPS on Low Brightness or Brightness Dimmer you need to download both CleanSlate Apps:
Please take a look at the CleanSlate thread for CleanSlate features. I will provide the link to the free to download apps here.
If you use the CleanSlate features and benefit over time, maybe think about giving something back to @tbalden and purchase them from PlayStore. :)

CleanSlate Configuration App (to control the features):

Dungun, MY
So what's the difference after?

If you mean CN to Global ROM, Global has no China bloatware. If you mean 32 to 47, here the changelog from Asus website.

1.Added “Quick launch camera” option in System Settings->Advanced
2.Added “Navigation blocking” feature for Game Genie which disables system gesture operations to avoid accidental touches in games.
3.Improved multi-touch when three or more fingers simultaneously touch the screen in games.
4.Fixed a problem with insensitive multi-finger touch response when playing PUBG

This is amazing, can't wait for the others to try and read their reviews..

So what's the difference after?

Just to steer this a bit in the right direction. This isn´t directed towards anybody in particular it´s just a general reminder what this thread is about.

There is no need to review the kernel. The kernel offers exactly what is described in the first post of this thread.
My advice is to read the description in the OP. All changes are explained in great detail there. Look around XDA, most OPs are kept way shorter with less explanations.
If you´re not into technical details, use google when descriptions or terms are unclear to you.
This is primarily a development focused thread. That´s why it is in the development section.
If there are issues when using the kernel or its features, provide logs and I will be glad to help you. If there are questions or things unclear, ask and I will try to answer. But I expect people to put in a bit of effort.


If you expect a review like, flashing this kernel causes my phone to use more or less battery as the stock kernel, you may want to re-read the OP on what to expect. I generally don´t like to see this in my threads.
Just to give an example that a "review" will never be applicable to each user:
Everybody uses their phone different. So certain changes to the scheduler may benefit user A, while they don´t benefit user B.
There is no need for a review. Just flash the kernel and try for yourself.

It´s very easy and straightforward to flash the kernel. And it´s also easy to return back to the stock kernel. If you don´t like it describe your problem as detailed as possible, as pictured in the FAQ and I will take a look at it or consider it. :)
Usually post like: "this kernel reduces my battery life by xyz" will just be ignored :)
It´s covered in the FAQ how to do all of this.



This is also a general reminder to everyone :) Let´s keep this thread development related and I hope this will turn out to be a good project!
I´m really looking forward to it. This phone is an absolute beast and so far I really enjoy using it.

For people a bit unfamiliar how everything works I plan to soon post a little guide on how to use the CleanSlate features.


Have a nice day everybody. :)

I thought its not working after i flash but suddenly all the features is needed an app CleanState Config/Companion i downloaded it and it works the 144hz in 0 brightness nice2. i will use this kernel as my daily bases.
I turn on the facedown to table to turnoff the screen or vibrate but its not working for me.

Edit: Its working btw there is a 1 sec delay after facedown :) so far so good.

    Update to 2.2.5

    Hey guys and girls,


    I hope everybody started into a good week. Here´s the next update it includes the source code for the latest firmware update.

    The kernel is now made for the firmware 17.0823.2104.147. Please make sure to update to this firmware before flashing the kernel to avoid potential issues. You can always flash the previous kernel, before I find time to update the kernel with the latest source, just don´t report issues if you decide to do so.


    Disclaimer/Important:
    Since Release 1.5.0 Selinux-Mainline patches are backported now that Magisk 21.0 and greater support it. This gives selinux a performance boost.
    You need to have upgraded to magisk 21.0 or higher before flashing the kernel!

    Kirisakura-Kernel for the Rog Phone 3

    Hello everyone,

    To keep it short: Here is Kirisakura - Kernel for the Rog Phone 3 aka OBIWAN.
    I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.

    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 project aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security and performance, while keeping stability as the foucs during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.
    Kernel Control Flow Integrity (Kernel-CFI), which is achieved by linking the kernel with LLD and Link Time Optimization (LTO), more precisely ThinLTO, are quite unique security features. In fact this, alongside Kirisakura-Kernel for the OnePlus 8 Pro, may be (and probably is) the first 4.19 msm kernel with a fully working Kernel-CFI implementation and CFI-Violations fixed on a smartphone.
    The only kernels made by OEMs offering this security feature are the ones for the Pixel 3 and Pixel 4 devices.
    The recently released Kirisakura-Kernel for the OnePlus 8 Pro was featured on the XDA-Portal due to the inclusion of CFI. The featured article explains CFI in great details, is easy to understand and definitely worth to read.

    Another security feature is Shadow Call Stack (SCS). Similar to CFI, only the Pixle 3 and 4 Kernel use this security feature.
    SCS is another security patchset that is aimed at preventing attacks via return oriented programming (ROP).
    ROP is a technique where the attacker gains control of the kernel stack to overwrite function return addresses and redirect execution to carefully selected parts of existing kernel code.
    If you´re interested here are a few good links:
    Google Security Blog explaining SCS.
    LLVM doc about SCS
    Android DOCs documenting SCS

    If reading about upstream in the paragraph above got you curious,have a read about Linux-Stable and why it is important here. The stable-process is not the same for every subsystem, but the general idea, rule of thumb and benefits are applicable for other subsystems as well.

    Quick explanation of CAF-Upstream. CAF is short for Codeaurora-Forums. This is the place where development from Qualcomm for their SoCs happens. This includes the Snapdragon 865/+ that´s built into the different SKUs of the Rog Phone 3.
    The kernel-bases available on the Codeaurora-Forums, are basically the foundations OEMs use, to build their own kernel additions on top for devices featuring Qualcomm SoCs.
    The Qualcomm developers push regular updates to the bases of the different SoCs, a bit similar to how Linux-Upstream works. OEMs usually stop updating the initial base after the phone is released.
    This kernel focuses amongst the other features to provide the latest CAF-Updates merged in a regular manner, to provide updates, improvements and enhancements for SoC specific drivers and subsystems! This might take a while, because a lot of device specific testing is done on my end to ensure stability.

    The kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
    I´d like to mention @tbalden ´s excellent CleanSlate features at this place. They improve usability by a big margin for me personally. The highly customizable sweep to sleep implementation (adjustable to different navigation settings), long tap to bring down status bar (very useful on a big device), backlight dimmer and notification reminder are very useful features that I use personally every day.
    Another big part of improvements originate from @arter97´s, @kdrag0n´s and @Sultanxda´s work. Many others contributed in some way or another to this kernel.
    A big thanks to all of them at this place!

    Now lets continue with a list of features in the next paragraph!

    Update to 2.1.0

    Hey guys and girls,


    Alright here´s a new update.
    It includes CAF-Upstream as well as Linux-Stable upstream.

    However there´s an interesting new change I´m sure many will be interested in.
    The display commands were changed so visibility in dark scenes is improved when watching videos on lowest brightness.
    Here´s an example scene from the "infamous" batman trailer. Both pictures were taken with lowest brightness setting on the phone and the same iso, aperture and shutter on the camera.

    Stock:

    New:

    These changes allowed me to greatly reduce the minimal brightness in the kernel, while still improving visibility and black levels on lowest or very low brightness setting compared to the stock kernel.
    If you don´t use already the brightness dimmer setting in the CleanSlate config app, the minimum brightness on a pure white background will now be by default on 3.7 lux, while it is on 13.5 lux on the stock kernel.

    If that´s too low for you and you prefer a brighter minimal brightness install the CleanSlate Config app and change the backlight dimming min value to your liking.
    The app is available to download in the CleanSlate thread.
    Here´s a screenshot, on which setting to change. Enable the dimmer setting, choose your desired min value with the slider, hit the save icon at the bottom and profit!
    The following are rough guidelines on the value you can choose in the CleanSlate config app and the corresponding min brightness measured against a white background.

    40 (default setting on my kernel, without having CleanSlate config app installed) = 3,7 lux min brightness
    90 =6,7 lux min brightness
    120 = 8,1 lux min brightness
    180 = 13,7 lux min brightness (same as stock kernel)

    You will notice a brightness/colour shift on low brightness once you open a "VideoApp" like YouTube, Netflix, Prime Video. The same happens to popular Gallery Apps like Google Photos or Asus Gallery.
    This is an overlay from the Pixelworks daemon that is triggered, when such an app is detected. This behaviour can´t be blocked in the kernel (yet, probably never).
    However there´s a trick to disable this mechanism. When using A11 navigation gestures, swipe up from the bottom so you can see the "pill". Drag the pill a little to the left or right as if you´d switch apps. You´ll see again a brightness and color shift, as the pixelworks daemon is fooled to believe you exited the app.
    That´s helpful if you want to watch the video on that "lower" unmodified brightness level.
    It´s not a perfect solution but better than nothing.
    Keep in mind, when using this trick on lowest brightness you will lose a bit of visibility of those dark details again.

    But it´s all about choices and I feel this offers plenty now.

    These changes to the display also shift colours on higher brightness a bit towards green. That means the "dark, red-blueish hue" from the ROG 3 is reduced and the screen looks more natural/neutral. I compared a lot with other devices and think I finally found a good spot, that´s hopefully acceptable for everyone.
    There´s always splendid to fine tune the display!

    I will also attach two kernel.zips. One with the display changes and one with stock "settings" for the display.
    So if you don´t like the new changes, you can just use like everything is on stock.

    Disclaimer/Important:
    Since Release 1.5.0 Selinux-Mainline patches are backported now that Magisk 21.0 and greater support it. This gives selinux a performance boost.
    You need to have upgraded to magisk 21.0 or higher before flashing the kernel!
    If you´re on of those that could not boot 21.0 or greater with the stock kernel, this issue is solved on magisk 21400 and above.

    Update to 1.9.4

    Hey guys and girls,


    New Update. It includes the source for the new firmware 17.0823.2012.131.
    Make sure to update to this firmware, before flashing the kernel so no conflicts arise.

    1.9.4 includes latest Linux-Stable Upstream as well as CAF-Upstream.

    I also created a magisk module to hide the hardwarestub service warning for those with converted devices on my kernel. No paid app is required for it. Flash it via Magisk Manager and the notification will be hidden.
    Please note that refresh rate can´t be changed when the module is flashed. To able to change refresh rate or to remove the module, simple remove it in Magisk Manager and do a full reboot. I´ll attach it to the third post on this thread. There will be no support for this module from my side and no other support for converted devices.

    Disclaimer/Important:
    Since Release 1.5.0 Selinux-Mainline patches are backported now that Magisk 21.0 and greater support it. This gives selinux a performance boost.

    Requirements

    - unlocked Bootloader
    - USB-Debugging in developer options enabled
    - latest adb and fastboot binaries
    - working adb and fastboot environment
    - magisk root


    How to flash the Kernel:

    1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Asus Stock-Firmware. When the Rog 3 receives an update it takes Asus a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
    Always make sure to run the firmware the kernel is built for!

    1a. Optional: While it may not be necessary all times, you may want to restore stock boot.img, re-root with magisk and optionally install twrp.zip if coming from another kernel. Before reporting issues make sure you do that! Thank you!

    2. Make sure to use at least Magisk 21.0. , otherwise your phone won´t boot due to Selinux-Mainline being present in the kernel. If you´re one of those that can´t use magisk 21.0 or greater on stock kernel, update to beta/canary channel in magisk manager settings, update magisk to 21.0 or greater via magisk manager, do not do a full reboot instead proceed to step 3 without a full reboot!

    3. Flash the kernel.zip via latest EXKM or FKM app, or TWRP (haven´t tested TWRP myself as I don´t need it) and do a full reboot.

    4. Reboot and profit.
