This is a direct port of my kernel on the international I9300 Galaxy S3 and sidekick to the international N7100/5 Note 2 kernels.

Recap of features:
  • CPU overclocking up to 1.8GHz and undervolting from 600mV to 1400mV.
  • GPU overclocking and undervolting.
  • GPU scaling reworked.
  • Screen sharpness and colour modifications.
  • Extended Pegasusq and improved Performance governors.
  • Removed Touch Booster and replaced with custom Flexrate mechanic.
  • Improved scheduler power management for improved idle residencies on auxiliary CPUs.
  • USB charging rate limit increased to 900mA.

This is supposed to be merely a proxy thread. Please refer to the N7100/5 thread for full changelogs, explanations, bug-reports and other issues. Kernel for specific device versions will be posted here.

This kernel is for the North American AT&T variant SGH-i317 and Canadian SGH-i317m for Rogers, Telus, Bell, and SaskTel. Versions for other variants are found in their respective forums.

@AndreiLux

Probably should mention in the op that this will work for i317m....to avoid it being asked a few times. There are many new users to Note 2.

Thanks!

Is the Zip flashable in TWRP? (I know some are only scripted for CWM). Answer=yes. I flashed in TWRP with no problems.

Also, has anybody flashed this yet? I am going to try it, but don't want to be the first! (Edit: I see blkghost is).

Has anybody that flashed it noticed if it eliminates the lag waking the phone from deep sleep? This is what I intend to test first on the kernel. Edit: nope

I can confirm this as well (just tried and it works fine).

For those who aren't aware, the i317m is the Canadian Galaxy Note 2, so for Rogers, Telus, Bell, and SaskTel.

AndreiLux - no issues came up. Seems to run the same as it did on the n7100 (which makes perfectly good sense.)

I added it, thanks for the heads up. Usually all variants with a post-fix will work, as they only have ROM related differences.

And the zip also works with TWRP.

Flash it yourself if you want to see he's provided stock kernels for you if you don't like it or want to revert.

@AndreiLux - I assume your compiling from 317 sources? Is your source on GH, or do you provide tar balls?

I'll try to save people some headaches and questions (though I know most won't bother to read.)

You can use "setCPU" from the play store to set min/max speeds, voltages, etc.

On undervolting... Every SOC (processor) is different. You have to test your own, as the settings that work for someone else might crash yours. If you aren't comfortable doing that, you might just leave voltages alone. So far, I'm seeing much lower voltages (better undervolt) on my i317 when compared to my n7100. However, others with the n7100 were able to undervolt much further than I was. They all have the same SOC (processor.)

You didn't read the OP?

edit: actually, that's kind of making assumptions... Follow the link in the OP for changelogs, etc. Source information is there as well.

I did. But why post it in the 7100 thread? It might confuse people. Granted they are 98% the same.

My fault then. Apologies.

Edit: I've been awake almost 30 hours. So possibly why I missed it and doesn't make sense to me. Lol.
