[KERNEL][08/11][3.10.102][UBER-5.4] Unofficial AK - 067 - Nexus 6P Android Development

Introduction
Hello everyone, this is my unofficial version of @ak's kernel. As he has been busy with life lately, I wanted to keep up with the Android security patches since this kernel runs amazingly on my phone; so I did just that. Because these are unofficial, you are NOT to discuss the use of them in ak's thread. Do that here. Read ALL of this post, I go over almost everything you could need to know. This kernel will only receive security updates and upstream Linux patches; I will not be changing anything else.
For those of you who have come here before, I have moved the more feature packed kernel to here: http://forum.xda-developers.com/nexus-6p/development/kernel-ninja-kernel-v1-0-t3437247
Differences from official
AK versions 064-066 (unreleased officially by ak)
Linux versions 3.10.74-3.10.83 and 3.10.102
August security patch
Patches for some CVEs
Compiled with latest Uber 5.4 toolchain
Downloads

Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: Keep in mind I am by no means a kernel developer. However, 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 and then provide me with a dmesg/last_kmsg and logcat plus your ROM/kernel version, I'll do my best to assist you.
Code:
adb logcat -d > logcat.txt
adb shell dmesg > dmesg.txt
1.3 Q: Can you add xyz feature?
1.3 A: Sorry, no. I will only be adding security patches. If you want a fully updated and feature packed kernel, check out my Ninja Kernel: http://forum.xda-developers.com/nexus-6p/development/kernel-ninja-kernel-v1-0-t3437247
1.4 Q: How do I control the kernel?
1.4 A: AK recommends using Synapse; if you do not care for Synapse, I would flash this UKM uninstaller in TWRP to keep your /data partition clean. Personally, I recommend using either @flar2's EX Kernel Manager or @Yoinx's Kernel Adiutor-Mod; both are extremely solid and have given me no issues.
1.5 Q: What are your settings?
1.5 A: Here are my regular/tried and true settings for what I consider great performance and battery life:
CPU:
CPU governor: Interactive
CPU governor (Cluster 2): Interactive
Stock governor profile
Max CPU frequency: 1708 MHz
Min CPU frequency: 302 MHz
Max CPU frequency (Cluster 2): 2054 MHz
Min CPU frequency (Cluster 2): 302 MHz
Input boost frequency: 0:768000 1:0 2:0 3:0 4:0 5:0 6:0 7:0
Input boot milliseconds: 60
msm_thermal: Enabled
core_control: Disabled
Graphics:
No modifications
Gestures:
Sweep2Wake: Up, Down
Camera launch gesture: Enabled
Sound:
No modifications
Memory:
No modifications (I leave zRAM enabled)
Miscellaneous:
No modifications (sioplus and 1536 are the defaults, which I use)
Thanks to:
@ak for the fantastic kernel
The various developers for their patches (@flar2, @franciscofranco, and @imoseyon to name a few)
@DespairFactor for helping me with some kernel compilation issues and the Uber prebuilt toolchains I use
All of you guys for viewing the thread
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.

How to compile the kernel for yourself
1. Configure your environment
In order to compile this kernel, I'd recommend using Linux (OS X should be acceptable but this guide will be tailored for Linux). To get the environment configured, either use Google's own guide here or my guide (only section 1) here.
2. Grab the source
Grab my AK source
Code:
mkdir ~/Android
cd ~/Android
git clone https://github.com/nathanchance/AK-Angler.git AK
Explanation:
First command makes a directory named Android in your home folder (mkdir = make directory). You can change the location if you want but keep it consistent throughout the guide.
Second command moves into that directory (change directory)
Third command pulls the source from my Github into a directory named AK (git clone <url> <folder_to_clone_in_to> is the format of the command).
Grab my AnyKernel source
Code:
cd ~/Android
git clone https://github.com/nathanchance/AK-Angler-AnyKernel2 AK-AK2
Explanation:
First command moves into the Android directory we made above (change directory)
Third command pulls the source from my Github into a directory named AK-AK2 (git clone <url> <folder_to_clone_in_to> is the format of the command).
Grab the toolchain you want to use to compile the kernel
Code:
cd ~/Android
git clone <kernel_url>
Explanation:
In order to compile the kernel, we need to grab a toolchain (bunch of compilation tools). I currently compile 11 options, you'll only be doing one. Below are the list of possible URLs to clone; copy and paste it after the words git clone above:
AOSP: https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9
Uber 4.9: https://bitbucket.org/DespairFactor/aarch64-linux-android-4.9-kernel.git
Uber 5.4: https://bitbucket.org/DespairFactor/aarch64-linux-android-5.x-kernel.git
Uber 6.1: https://bitbucket.org/DespairFactor/aarch64-linux-android-6.x-kernel.git
Uber 7.0: https://bitbucket.org/DespairFactor/aarch64-linux-android-7.0-kernel.git
Linaro 4.9: https://android-git.linaro.org/git/.../aarch64/aarch64-linux-android-4.9-linaro.git
Linaro 5.4: https://android-git.linaro.org/git/.../aarch64/aarch64-linux-android-5.4-linaro.git
Linaro 6.1: https://android-git.linaro.org/git/.../aarch64/aarch64-linux-android-6.1-linaro.git
DF-Linaro 4.9: https://bitbucket.org/DespairFactor/aarch64-linux-android-4.9-kernel-linaro.git
DF-Linaro 5.4: https://bitbucket.org/DespairFactor/aarch64-linux-android-5.x-kernel-linaro.git
DF-Linaro 6.1: https://bitbucket.org/DespairFactor/aarch64-linux-android-6.x-kernel-linaro.git
3. Setup the build
Make sure everything looks right
After following the above steps, type:
Code:
ls
You should see something like this:
Code:
aarch64-linux-android-6.x-kernel-linaro AK AK-AK2
The toolchain directory make be different depending on what you cloned above. If it looks different, delete the Android folder and do step 2 again.
Select the correct kernel branch
Code:
cd ~/Android/AK
git checkout <branch>
Example:
Code:
cd ~/Android/AK
git checkout m-eas
Explanation
First command will move you into the AK source directory we cloned above.
Second command will checkout the branch you want to compile for. A git repo can have multiple branches. For mine, these are the possible options:
m-standard (for the M Normal branch)
m-eas (for the M EAS branch)
m-nethunter (for the M NetHunter branch)
n-testing (for the N Normal branch)
Select the correct AnyKernel branch
Code:
cd ~/Android/AK-AK2
git checkout ak-angler-anykernel
Explanation
First command will move you into the AK AnyKernel directory we cloned above. This is what allows you to flash the kernel (thank you very much @osm0sis for all the work you do).
Second command will checkout the correct branch (in this case, ak-angler-anykernel)
4. Make the kernel
Tell the makefile what toolchain and architecture you are building for
Figure out the full path of your toolchain folder
Assuming you have done this whole process correctly, you can move into your toolchain directory and type:
Code:
cd ~/Android/<toolchain_folder>
pwd
Example:
Code:
cd ~/Android/aarch64-linux-android-6.x-kernel-linaro
pwd
You should get something like this:
Code:
/home/nathanchance/Android/aarch64-linux-android-6.x-kernel-linaro
Tell the compiler where that toolchain is
Copy and paste that file location above into this command:
Code:
export CROSS_COMPILE=<toolchain_dir>/bin/aarch64-linux-android-
Example:
Code:
export CROSS_COMPILE=/home/nathanchance/Android/aarch64-linux-android-6.x-kernel-linaro/bin/aarch64-linux-android-
Set the architecture
Angler is a 64-bit device so we need arm64
Code:
export ARCH=arm64
export SUBARCH=arm64
Clean up from a previous compilation and update the source
Code:
cd ~/Android/AK-AK2
git reset --hard origin/ak-angler-anykernel
git clean -f -d -x > /dev/null 2>&1
git pull > /dev/null 2>&1
cd ~/Android/AK
git reset --hard origin/<kernel_branch>
git clean -f -d -x > /dev/null 2>&1
make clean && make mrproper
Example:
Code:
cd ~/Android/AK-AK2
git reset --hard origin/ak-angler-anykernel
git clean -f -d -x > /dev/null 2>&1
git pull > /dev/null 2>&1
cd ~/Android/AK
git reset --hard origin/m-standard
git clean -f -d -x > /dev/null 2>&1
make clean && make mrproper
git pull
Explanation:
First set:
The first command moves you into the AK AnyKernel directory.
The second command will undo any local commits you have done and align your source with the most recent commit from me.
The third command will clean any untracked or compiled files (this is send to /dev/null so you do not see it happen).
The fourth command will pull any new AnyKernel changes from me into the source.
Second set:
The first command moves you into the AK source directory.
The second command will undo any local commits you have done and align your source with the most recent commit from me.
The third command will clean any untracked or compiled files (this is send to /dev/null so you do not see it happen).
The fourth and fifth command (strung together with &&) will remove you
The sixth command will pull any new kernel changes from me into the source.
Set up the defconfig
A defconfig tells the compiler which features you want in the kernel. This is already set up by me. To set up the defconfig, type the following:
Code:
cd ~/Android/AK
make ak_angler_defconfig
Name the kernel
If you notice in About Phone > Kernel Version, it shows 3.10.102-AK.066-9.UBER4.9 (or something similar). You can customize this like so:
Code:
export LOCALVERSION=-"kernel name"
Example:
Code:
export LOCALVERSION=-"AK-Nathan-Personal"
Make the kernel!
Code:
make -j#
Example:
Code:
make -j4
Explanation:
The # after the "j" is how many simultaneous threads are run. Traditionally, this is the number of cores you have plus one. So a quad-core CPU would be -j5.
5. Zip it up and flash!
Copy the zImage to the AnyKernel directory
Code:
cd ~/Android/AK/arch/arm64/boot
cp -v Image.gz ~/Android/AK-AK2/zImage
Explanation:
We need to copy the newly compiled kernel (which resides in the arch/arm64/boot folder) to the AnyKernel directory, while changing its name to zImage.
cp = copy
-v = verbose (prints the copying)
Image.gz = file to be copied
~/Android/AK-AK2/zImage = destination and name
Make a current dtb file
Code:
cd ~/Android/AK-AK2
tools/dtbToolCM -v2 -o dtb -s 2048 -p ~/Android/AK/scripts/dtc/ ~/Android/AK/arch/arm64/boot/dts/
Explanation:
No explanation, just do it :silly:
Zip it up!
Code:
cd ~/Android/AK-AK2
zip [email protected] -r9 ak-kernel.zip *
Using the above commands, your newly completed kernel will be located at ~/Android/AK-AK2/ak-kernel.zip
If you followed all of the above steps successfully, congratulations, you built the kernel!! Once you have done all five steps, you will just need to follow steps 4 and 5 to update in the future. Below, I have linked a script that will do all of this for you (with some variable edits at the top); however, please do it manually first so you know exactly what you are doing enjoy!

Sure. They are added in the OP and will be updated if I ever change them.

OK, i'll try that. Thanks for sharing

---

Thank you the kernel.
I use Resurrection Remix ROM with ElementalX kernel. Can I install the AK.066-2.ANGLER.UBER6.1.zip after the ElementalX kernel? Or should I go back the apascual kernel and then install the AK.066-2.ANGLER.UBER6.1.zip?

Hey thanks for this Nathan, you've done an excellent job. This is the smoothest kernel I've tried. Running RR it is very smooth.
