They all pretty much are flash and forget. If you like stock, the go with Ex or sultan. If you like the latest upstream changes, then go with kiri kernel. Kiri and Ex have more tweaks available, whereas sultan stays very close to stock, but offers great performance as well. Personally, I'm an Ex fan, and have been for years :cool:

Could you please supply a link to the Kiri thread. I'm an EX fan myself, as well, but with Flash gone, I am curious about other kernels. Thank you,

Grandfather! That's great. Congratulations, I'm sure you will have a wonderful time as he grows up :)

Can you flash that Kernel directly over EX or Flash? Or do you need to only flash over stock?

Thanks my friend! Being a grandpa is too dang fun. According to the Dev, he recommends just flashing it in twrp, then flash magisk again. He really doesn't say if you can flash it over stock or another kernel. However, I've seen others flash it over different kernels. Personally, I'm old school when it comes to flashin kernels. I like flashing the stock boot.img, then twrp.zip, then kernel, then magisk. But that's just me :cool:

If you want a true "set it and forget it" kernel, I suggest Elemental X (EX). If you purchase the EX Manager app ($ well spent) and run EX kernel, it will auto update (prompt) every time a new kernel update is dropped.

So all you literally have to do it select "yes" to updating the latest kernel and you're on your way until the next one drops.

EX Manager also allows for quite a bit of customization (colors, gpus, cpus, governors, etc.) when you feel like tinkering.

It may not be the most cutting edge, the most aggressive, or the most battery efficient; but it is certainly excellent, amazingly stable, and consistently solid.

Yep, running EX right now, no customizations, just defaults. I've been waiting for Sultan to drop a Dec build, but it was time to get the Dec security updates. Nathan ruined us with his builds every few days!

Dude me too. One thing I miss on this device is the lack of someone creating twrp flashable zips each month with the stock kernel. It's above my pay scale, but it was always a nice option for those of us who can't sit still. Lol

Yeah, that was a pretty sweet deal back in the day, along with bootloaders and radios. Although, flashing the boot.img in twrp isn't too bad either :cool:

If you want a kernel that is going to be similar in feel and stability as Flash, look no further. You can flash it via FK Kernel Manager, you just won't have the auto update feature.

    Introduction

    NOTE: This kernel is currently not being updated. I recommend using Sultan's kernel instead.

    Hello everyone, this is my personal kernel for the Pixel 2 (walleye) and Pixel 2 XL (taimen). I only own the latter but the kernel is fully unified. While I am not a super star kernel developer, I do know my way around it. My philosophy on kernels is pretty simple:
    • Follow stable Linux always. Updates will be delivered within 24 hours of their release to kernel.org.
    • Stable kernel rules work best (only add small things when possible).
    • Security and stability are paramount. Vulnerabilities are patched as soon as they are disclosed.
    • Features will be added only as needed (I have a list of things in the FAQ I will NOT add, even if requested).
    Hopefully you enjoy :)


    Important thread information!

    1. I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this.
    2. Keep things civil, I do NOT tolerate flaming of any kind.
    3. OT is allowed.

    Features
    Here are the major features of the kernel (feel free to explore Github)
    • Up to date with the November security update (android-9.0.0_r0.37) [see device specific notes below]
    • Up to date with the latest stable Linux version (4.4.162)
    • Patches from Code Aurora Forum targeting GPU, touchscreen/video, storage, and sound
    • Kernel hardening from CopperheadOS
    • Mainline Linux patches for CFQ and media memory allocation
    • Latest energy aware scheduling patches from kernel/common's android-4.14 branch
    • Several subsystems converted to use power efficient workqueues
    • Westwood as the default congestion algorithm
    • Optimized input and wake boosting and other optimization from Sultanxda
    • The following user facing features:
      • KCAL color control
      • Minimum/maximum backlight control
      • Vibration control
      • Wake gestures (thanks to @flar2)
      • Wakelock control
    • Latest WireGuard snapshot (0.0.20181018)
    • Built with a self compiled Clang 7.0 toolchain with a local initialization sanitizer (previously built with the latest Google Clang 6.0 toolchain here)
    • Hides bootloader unlock from SafetyNet (can still fail through other means)
    • Available to flash with AnyKernel2 (thanks to @osm0sis) [zip will automatically detect when Magisk is installed and patch the kernel so reflashing Magisk becomes unnecessary]


    Downloads

    Primary: https://github.com/nathanchance/wahoo/releases

    It is called Wahoo as that is the unified name for the Pixel 2 (walleye) and Pixel 2 XL (taimen) [link 1 and link 2].


    Installation

    NOTE: These sets of steps should work for both initial installations and upgrades. All sane kernels on this device are just replacing the kernel image and maybe adding some cmdline parameters, which this kernel won't care about. If there are ANY issues after flashing this kernel over another, be sure to flash the stock boot image for your ROM, TWRP + Magisk if you want them, then the kernel before reporting any issues.

    Through TWRP:

    See their instructions for further information, you can install the kernel with TWRP temporarily booted or permanently installed.

    1. Boot into TWRP.
    2. Flash the zip (flashing Magisk is not necessary if you already have it installed).
    3. Reboot and enjoy!
    Through FK Kernel Manager (requires root):

    1. Download the zip (and optionally, the md5) from my server
    2. Tap on "Manual flasher"
    3. Navigate to Download
    4. Tap on the zip, select Auto-flash, and choose one of the options.
    5. Reboot and enjoy!

    Frequently asked questions
    1.1 Q: I am having an issue, can you help me?
    1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably, I'm not going to fix the issue.

    1.2 Q: Can you add xyz feature?
    1.2 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration. I will NOT add the following:
    • Overclocking or underclocking of CPU or GPU
    • Undervolting
    • Any governors other than schedutil
    • Any schedulers other than cfq and maple
    • Anything that compromises performance

    1.3 Q: How do I control the kernel?
    1.3 A: I want to be very clear: the kernel does NOT need to be tuned to be useful. Most of the improvements are under the hood and don't require any user intervention to take advantage of them. In fact, if you don't know what you are doing, you could degrade the experience.

    To control the user visible features of the kernel listed above, I recommend using either @franciscofranco's FK Kernel Manager (which has Flash Kernel support for downloading and automatically flashing the latest kernel zip along with some nice, user friendly ways for tuning the kernel) or @flar2's EX Kernel Manager.

    1.4 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
    1.4 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.


    Thanks to:
    The various other developers for their patches (specifically @zx2c4 for WireGuard)
    @osm0sis for AnyKernel2
    @franciscofranco for adding Flash Kernel support to FK Kernel Manager
    @phantom146 for the thread banner
    All of you guys for viewing the thread


    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.

    Update to 3.19!

    This will be the last build of Flash indefinitely. I am stepping back from Android as I have become exhausted with all of the work of staying up to date. I recently started a new job, which has consumed most of my free time, and I have been contributing to ClangBuiltLinux, a collaborative effort to get Clang support streamlined upstream. I got 85 patches into Linux 4.20 (97 total since the beginning of September) and I've contributed quite a bit to the continuous integration setup (not bragging or anything, just showing where my time has gone). I am not saying I will never be back but for right now, I will not be pushing any more builds.

    I am leaving the thread and Telegram group open for everyone to hang out in. I definitely recommend using @Sultanxda's kernel if you want something that is more up to date. He is obviously extremely talented and you'll be in good hands (maybe he'll start merging linux-stable? :p) I'm not leaving the scene by any means, I'm always happy to answer questions. Enjoy and cheers!
