With the help of several people, I'm proud to bring you Cortex Kernel! This is my first independent kernel, and as such, is a constant WIP. Of course, things will be broken. I will fix what I can as I learn more about kernel development. Just hang in there, it's worth it!​

NOTE: SDCARDFS may be unstable. Use at your own risk!
To enable SDCARDFS, I quote @freak07:
1. Open the file system/build.prop and add the line "ro.sys.sdcardfs=true" without the quotes at the bottom and
Make sure your selinux is set to permissive. You can either do this via an app or via script.
here is the download for a script: https://www.androidfilehost.com/?w=files&flid=155912
2. Extract the script and put it in either system/etc/init.d or /system/su.d or /su.d
3. Set the file´s permissions to rwxr-xr-x (755)
4. Reboot.

I'm hoping. Working with the Pixel isn't anything like it is for the Nexus 6P. I'm still figuring it out.

Oh man, that's great news bud, good luck! Just flashed the kernel. Does this have the sdcardfs commits to be compatible with sdcardfs?
EDIT: nevermind I checked GitHub, didn't see them. Thanks man, testing it now

Just a couple feature requests should be easy ones. High brightness mode, backlight dimmer, and to be able to block all the wakelocks ex kernel manager, there's a slew of them, not sure the commits. One last possible would be high-speed congestion control. Sorry, longer than I wanted, but the high-speed is secondary.

It has sdcardfs, but it's completely stock. For the time being, I chose not to commit anything to it. So no current plans to support it. I'm hoping to make this a lean type of kernel, with a few tweaks available. I play Dawn of Titans a lot, and having smooth gameplay is something I look for in a kernel/ROM. Hopefully my kernel (and upcoming ROM) will work perfectly together and create a great platform.

Sounds like a plan. Sdcardfs isn't a dire need, lol. Just wondering. So you're saying if I add the build.prop commit for sdcardfs it won't work right? Also looking forward to what this brings, it's running incredibly smooth since booting.

---

I'm not sure honestly. I think it'll work, but not very well. People have made LOTS of patches to it to improve it. I might if I get the time, but thats last on my list.

Probably you will face a lot of crashes when accessing storage.

Also @chevycam94 Congratulations :good:

I had a freeze and reboot to ram dump. Your not the only kernel. Happening on Franco and kirosuko as well. Maybe check there commits and threads too. I couldn't get log but go others that is helpful. KMSG here, https://drive.google.com/file/d/0Bw-ARc6DtAVJUHdWYnlaSmMza1k/view?usp=drivesdk. Other is attached

Could a couple of you test this kernel build for me? I'm having a fight with my build system. I'm getting 9 "section mismatch" errors, and I am scratching my head to the bone trying to figure out whats going wrong. My code built fine on my last VM, but I screwed up and killed that one. Now my new setup, same OS, same toolchain, same code, builds with 9 errors. I have to force it to ignore those errors (which I didn't have to do before), so I have no clue if this even works now. I would think it would, seeing as the code was functional before, and hasn't been changed since.
Test the crap out of it. I know it still has the regular issues some other kernels have, but it should otherwise be fully functional.......SHOULD
UPDATE: I managed to find some time to test it. So far, it's working fine. Some things spam the crap out of logcat, but that's ok. Compared to the stock kernel this is instantly faster. HUGE difference. Wasn't really expecting it to be that noticable. Nothing has crashed so far. If all goes well, I'll start work on the next release. v1.0.9 isn't meant to be a public release BTW. It's simply in the testing phase. But if you like it, feel free to use it! Just know that it's not officially supported in any way.

PERFORMANCE TWEAKS:
Use these tweaks to really get some kick....um....butt, performance from your Pixel XL! I'm on my v1.1.0 kernel (unreleased), but it's essentially the same as the v1.0.9 zip I just posted for testing. HUGE difference in the phone!
Chage the following items to the given values:
Code:
dirty ratio: 40 (default=20)
dirty background ratio: 10 (default=5)
overcommit ratio: 35 (default=50)
swappiness: 40 (default=60)

v1.1.0 is up

You can find them in the 'Virtual Memory' section of whatever kernel manager you are using.

Honestly, I'd spring the money for EX Kernel Manager. @flar2 has made a nearly perfect app to control just about everything you could need. It's not designed to be a "toolbox", but rather just a place to set options for the system, kernel, cpu, gpu, and memory, for the most part.
He still needs to update the live CPU display on the main page, as its not accurate, or even right (at least on the Pixel). Along with odd CPU frequency selections (they dont always become what you select, depending on kernel/setup). There are one or two other things, but I don't remember off the top of my head.
But regardless, it's the best kernel control app I know of right now. Most friendly for me. Also give you widgets/notification icons for "performance mode" and "power saving" mode. Quick toggles. Love that part.

Will the battery consumption got huge difference too? Lol

Battery life is about the same, or slightly better. At least for me. Depends on your setup.
