Introduction
Hello everyone, this is my kernel for the Nexus 6P ported on over to the Nexus 5X. I won't claim that you will get hours upon hours of battery life (even though optimization really is my focus here) but I will say I have added quite a few options for you guys and the optimization patches should improve your experience with this device. Hopefully you enjoy! Please read this entire post, most of your questions will be answered in here!

If you would like to be notified of updates outside of XDA and/or get beta releases, follow my Telegram channel here (and join up with my Telegram group here for casual discussion)! Additionally, please do not mirror my kernels. I have provided two links that will have nearly 100% uptime and I will be aware if they go down and provide appropriate measures.

Customization
Since the whole point of installing a custom kernel is to have more options available to you, here is some information regarding the tweaks available in the kernel.

Default settings: the phone will boot with the following settings (the ones I recommend sticking with if you are not into tweaking):

  • Governors: interactive on both clusters
  • Frequencies: 384-1440MHz on little and 633-1824MHz on big
  • Input boost: 1248MHz on little and 768MHz on big for 40ms
  • core_control on, msm_thermal off
  • Wake gestures and backlight dimmer disabled
  • Adreno Idler enabled
  • Sound controls set at 0
  • ZRAM enabled and UKSM disabled
  • zen at 128kb
Governor profiles: If you want to try and squeeze a little bit more battery life out of your phone or increase performance, you may consider exploring governor profiles. Below are some links to various posts containing links/descriptions of these profiles:
From @soniCron - HawkTail, GlassFish, and FairPark
From @Alcolawl - list of profiles

Virtual memory: I have implemented ZRAM and UKSM in the kernel and there are many ways to tweak these. I would only recommend messing with vm_swappiness but you can read about ZRAM tunables here and UKSM tunables here. To make the kernel use more or less ZRAM, type this in a terminal emulator (or change it in EX Kernel Manager under the Memory section):
Code:
echo # > /proc/sys/vm/swappiness
This number can be between 0 and 100. 0 will make the kernel swap to ZRAM only if there is an out of memory error, 100 will make the kernel swap to ZRAM as much as it can. I set it at 15 by default, I would set it to 1 if you don't want to use it as much as 1 will use the minimum amount possible (basically when the phone is super under load). Highest I would go is 60 (which is the stock/default value in the Linux kernel). Read more about swappiness here. Additionally, UKSM is disabled by default. You can either enable it with EXKM or echo 1 to the sys path /sys/kernel/mm/uksm/run


Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not a superstar 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. With that, I'll do my best to assist you.
Code:
adb logcat -d > logcat.txt
adb shell dmesg > dmesg.txt
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.


Thanks to:
@REV3NT3CH for showing me what a good developer and kernel looks like
The various developers for their patches (@ak, @Buckmarble, @flar2, @franciscofranco, @frap129, @imoseyon, @jollaman999, and @Yank555 to name a few)
@osm0sis for AnyKernel2
@mdalexca for helping me with some kernel compilation issues and the prebuilt toolchain I use
@kwoktopus for giving me good advice on Makefile flags and other patches
@malybru for my nifty new signature and 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.
