I'm thinking chikimonke was being a bit cheeky and monkeying around with that comment
What was wrong with my comment? I don't see latest Linux versions merged with both kernels compared to kirisakura and flash. Am I wrong?I'm thinking chikimonke was being a bit cheeky and monkeying around with that comment

I have no idea whether or not you're right or wrong... But I know chiki and my presumption was about his comment, and more of a play on words than anything provocative or indicting.
"His" would be me in this case and still I have no idea what words I have been using the wrong way. Was trying to use the common terms used here so if something was wrong I'd like to know just to avoid the mistake. I mean I know that upstreamed usually means getting code changes merged to the upstream repo and might not be the totally correct term here.
Upstream just means getting the latest patches from the Linux kernel that the stock kernel is based on. For the Pixel 2 devices, that's 4.4. Google is notoriously behind the actual Linux kernel, so some devs take it upon themselves to grab the patches from upstream. However, it does not mean they are grabbing features from a different kernel base entirely, like 4.9, that would be porting and tends to break stuff or and best, bring very little to the table.
And as much as I'd like to take credit for being "chiki" I was legitimately asking, as I hadn't looked at another kernel besides Flash I'm quite some time.
Yes my kernel is upstreamed with the latest linux-stable patches! Flash kernel and my kernel share many commits besides upstream. CAF patches and more patches from kernel/common.
My kernel has a few backports from the 4.9 kernel which improve the kernel. Some eas changes are backported, as well as the ZRAM implementation and for example lowmemorykiller which improve multitasking/memory management quite a bit
Before I released these changes I tested them for nearly a month to make sure they’re stable!
The reboots seem also to be gone since the last two updates as UV and some other commits were removed. At least no one reported reports in my thread. I never faced a reboot with UV. I’m glad it seems to be solved now.
So you’re invited to come over to my thread if you care about linux-stable upstream!
I try to provide the best support I can and if you face issues gather logs and I gladly look into them!

Where's Nathan when you need a quick kernel update for the Dec patch ...
Releasing Canary builds over at Telegram whenever he feels for it.

I'm SUPER lazy.... if I give you a "thanks" will you just tell me the better secret
I'm SUPER lazy.... if I give you a "thanks" will you just tell me the better secret
maybe i'm just a n00b (just installed telegram) but i didn't see anything i was hoping for? I too want to be in on the super secret...

PM me
Is there a general consensus about the best kernel for the Pixel 2 XL these days? I'm just looking for something that works as effortlessly and perfectly as this kernel.
Too subjective of a question. Having said that, you won't be disappointed with any of the current kernels out there. They're all great Devs :good:
What if I rephrase a bit: is there one that I can just flash and forget? With this kernel I'd simply flash it in TWRP and then forget about it; I didn't have to apply any tweaks or do anything else besides flash it. It was completely stable (no reboots or anything,) it didn't hurt battery, didn't hurt performance, and didn't interfere with anything (apps, or other functionality.). Anything like that now?

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).
Important thread information!
- 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.
- Keep things civil, I do NOT tolerate flaming of any kind.
- 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]

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:
Through FK Kernel Manager (requires root):

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.

DISCLAIMER: I openly welcome off topic in my threads. Mods, please do not clean off topic discussion and users, do not complain about off topic discussion here. I may direct you to another thread if it is so suited but I won't have the discussion cleaned. Thank you.78Update 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?) I'm not leaving the scene by any means, I'm always happy to answer questions. Enjoy and cheers!
