[ANGLER] [8.0.0] [3.10.107] [GCC 7.2.1] Flash Kernel v3.1

Introduction

Hello everyone, this is my personal kernel for the Nexus 6P. While I am not a super star kernel developer, I do know my way around it. My philosophy on kernels is pretty simple:

• Follow upstream Linux always
• Stable kernel rules work best
• Security and stability are paramount
• Features will be added only as needed

Hopefully you enjoy


Thread Rules

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. More on bug reporting policy here.
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)

• Updated to the latest security patch on the latest Android version (August on Oreo)

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 though, 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.

1.3 Q: How do I control the kernel?
1.3 A: I'd recommend using either @flar2's EX Kernel Manager or @Yoinx's Kernel Adiutor-Mod; both are extremely solid and have given me no issues.

1.4 Q: What ROM are you on? What are your settings?
1.4 A: Currently, I am on Dirty Unicorns and my settings are available here

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

@neobuddy89 for always providing great fixes and being a shining example of a great kernel developer
The various other developers for their patches (@ak, @Buckmarble, @flar2, @franciscofranco, @frap129, @imoseyon, and @Yank555 to name a few)
@osm0sis for AnyKernel2
@DespairFactor for helping me with some kernel compilation issues
@kwoktopus for giving me good advice on Makefile flags and other patches
@kantjer for being a beta tester along the way!
@malybru for my nifty new signature!
@phantom146 for the thread banner and default profile GlassCannon
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.

Welcome to Flash Kernel 2.0 so to speak; this kernel has been completely rebased from the ground up. I have learned a lot in these past few months about what should and shouldn't be added for the best overall experience. So rather than fix my source in steps, I just decided to start from scratch so to speak. Here's what I did:

1. Grabbed kernel source straight from Google fresh
2. Picked upstream Linux commits from kernel.org, fixing conflicts again (as I had messed some up before)
3. Added known working patches (like governors, I/O schedulers, file systems, and such)
4. Went through the remaining patches, evaluating what the patch exactly did, and locating the original source to see if it had been altered
5. Left out anything that was not relevant or helpful to our version
6. Cleaned up dmesg a ton, by removing spammy logs and warnings that should not have been happening

At the end, I have a much cleaner and stable kernel. You may notice that some of your favorite features are missing, that's not by accident. The part that got me really down a little bit ago is I felt like this process was going to be a waste. People have so many preconceived notions about kernels, like that they will give so much more battery and performance and it's hard as a developer to shake off those things. I've seen so many people in both this thread and a few others rave about and disparage this kernel for completely subjective and inaccurate reasons. While I don't necessarily care about number of users, it's disheartening to see something that I put out for free without absolutely no expectation of reimbursement get a bad rap. But I've just decided to ignore it or correct it when I can. If someone blames my kernel for their drain, so be it. I do this because I use my kernel myself and I like doing it, I hope you guys can respect that. Also, bug reports are going to change a bit. If I cannot reproduce your issue myself, I'm not going to fix it. Simple as that, I cannot go on wild goose chases for issues I don't experience. Logs will still be required but steps to reproduce will be as well. Anyways, off my soapbox lol, enjoy the kernel guys.

Alright guys, I am going to be changing up how I do things around here.

1. Kernels will no longer be versioned as they will become daily, built from my personal branch. What this means for you is that you will get the kernel as I customize it (my custom settings from the OP as well permissive SELinux at boot) and some stuff may or may not be broken.
2. I will no longer be taking bug reports (I will attempt to fix the Android Auto issue as a grandfathered thing). If it works, perfect; if not, it's most likely not a problem for me so I won't care.
3. The thread will be closed for now (my Telegram channel will still be open for chatting and hanging out and the thread may be open eventually).

I have become very worn out checking my threads all the time and maintaining multiple branches so I am going to simplify it. The experience should not change, only the process. Thanks for everything and I will still be around XDA in various capacities, I just don't have the time to continue maintaining the thread as I would like.

The end of an era

It's with a heavy heart that I announce the end of Flash Kernel development for the Nexus 6P. I simply do not have the time to support this, DU for the 6P, and Flash Kernel for the OnePlus 5. I didn't want it to come to this but the recent issues with pretty much all custom ROMs has caused me to make this decision. For the record, I don't think these issues are because of the kernel but to eliminate it as a factor, I'd need to rebase the kernel from scratch and there is zero way I'm going to be able to do that. Rather than give you guys false hope or tarnish the kernel's name, I am just going to bow out. Joe Maples is most likely going to continue working on Electron so if you want a good kernel to migrate to, that one is it. However (and I say this having loved my time on the device), I would highly consider upgrading your device. The 810 was really a terrible chip in the long run and either an 821 or 835 device is going to make a HUGE improvement. I can consistently get 5-6 hrs of SOT without any issues on the OnePlus 5; I only did that in the first couple of months with this device. The Pixels (1 and 2), Essential Phone (once they get kernel source released and maybe shore up some camera issues), and the OnePlus 5 are all awesome destinations and should hold up much better than this device.

It was great learning and talking with you guys in here. You're always welcome in Telegram (I will leave this chat open) or in my other threads.

The Flash (Nathan)

Alright this thread is reopened for the time being, I will be revamping the OP here shortly with some new rules for how this thread is going to run.

1. I refuse to accept/respond to bug reports that don't include a logcat, dmesg, and if applicable, a ramoops
2. The kernel will boot with my personal settings (these can be changed after boot by a kernel manager) and while I will try to keep the OP up to date, you will need to read my init script to know for sure what is being set.
3. There will be no changelogs or versions; I will build when I am able to and the changelogs will be my commit lists:
https://github.com/Flash-ROM/kernel_huawei_angler/commits/n7.1.1
https://github.com/Flash-Kernel/AnyKernel2/commits/angler-flash-personal-7.1.1

Other than that, have fun and enjoy the kernel.
