[Kernel] [1/25] Simple Stream - Nexus 9 Original Android Development

Simple Stream is what I wanted to make a while ago
about being simple, small and up-to-date with google and Linux.
It will have optimizations here and there but for the most part it will be stock
But with updates! Simple Stream = upstream stock AKA what stock should have been.
This will only boot on new Stock/AOSP ROMs
i do not plan to support CM ROMs.

Known problems
You tell me

Is the only difference between this and fire and ice that this one is for stock roms? I wanted to say keep up the good work and it's because of you that my nexus 9 is even remotely usable.

Thanks man!
Simple Stream is what I wanted to make a while ago
about being simple and up-to-date with google and Linux
It will have optimizations here and there but for the most part it will be stock
But with updates! also with this one I'm keeping selinux enabled.
So the differences are it will be mostly stock.
Simple Stream means upstream stock

do you guys want me to add OCing?

Yes please.
SELinux permissive or enforcing? (I expected enforcing, like stock.)
I really like the philosophy behind this kernel.

I'd rather just have an enhanced stock kernel with no oc Have used your fire-ice kernel and found that it gives me lags whereas with stock my device runs quite well (as well as this ****ty device runs anyway!!) TA.

What if he allows OCing while setting the default frequencies to stock?
Does simply allowing the option for OCing cause problems?

you should be able to set it to enforcing
the reason i set it to permissive is because root does not like enforcing well
but if you want me to set it to enforcing i can do that too

Would choice of rooting method effect which SELinux mode we should pick?
Like SuperSU 2.62 systemless vs standard SuperSU 2.52?
I am using 2.62 with stock 6.0.1 currently. No probs yet.

standard SuperSU 2.52 needs permissive
2.62 don't know but most likely it will work on enforcing.
I prefer having it permissive because it will save headaches in the future.

He has a boot.img mod for the standard SuperSU that allows setting SELinux to enforcing.

Edit: It looks like you would need to make a zip for every Android release, but most of us are going to be on the latest, so that might not be much of a problem.
Edit2: According to my setup, SuperSU 2.62 needs no extra work beyond just flashing the zip to allow Enforcing. So, if you require SuperSU 2.61+, enabling Enforcing would be easy (for now).
Code:

ro.build.version.release=6.0.1

SuperSU 2.61+ solves that problem.

i will keep it permissive.
if one wants to enforce it
just run "setenforce 1" as root
Note: enforcing mod will be allowed in 1.2

I too find that Simple Stream kernel is smoother than Fire-Ice.
Edit: After a few hours of use, Simple Stream makes my tablet run hotter. Flashing back to Fire-Ice ?
