I think you might be following the development of cm12 for N7000.The dev has released Alpha3 but still it doesn't have either root nor recovery since there is no kernel supporting 5.0 for N7000.
I know you must be very busy and this maybe a bit too much to ask but I would like to kindly request your help and expertise in this matter :)
since I think raw kernel was the first to support KK ROMs maybe you could make another kernel that supports Lollipop/5.0 :D

REVENGE SOLVES EVERYTHING

At last, I can finally post in here now. Thanks for this wonderful kernel! As of now, I'm using Aryamod v8 + Forest Helloworld Make II AM1, and I just flashed the r3 for TW 4 hours ago. I can say that I can feel its snappiness especially when scrolling (60hz) and other noticeable increase in performance, however I do have some issues in hand and few questions.

I'm not pretty sure if this is kernel or ROM related issue but, while playing HD games (Battleheart Legacy) my cpu frequency fluctuates between 500 to 800mhz at first, then gets stuck/ locks at 500mhz after several minutes. I know that this is somewhat related to Thermal Throttling/ CPU throttling thingy (I don't really have that vast knowledge nor the difference about it), but is there anything I can do to prevent it from happening? After reaching 67C, it gets stuck at 500 mhz and the game starts to lag. Or should I just wait after several discharge cycle until the kernel "blends" with the ROM? Thanks in advance.


Edit: Okay, I think it has something to do with the Thermal Throttling thingy. Is there a way to disable it? Or maybe even adjust it? I've read that there are instances where they've set it around 70C to 80C (LG devices), dunno with n7000 though. Yes, I know the risks involved, it is a safety mechanism after all.

on slimsaber 16.11 i flashed both files (grelock... and 59 kernel) all went fine, including boot animation. in about phone kernel is geeko 60+... No problems. is this ok???? i understand i have to have that bright light problem while booting.

Have you tried putting your Note in the fridge? :D

Once I get back my desktop pc I'll try to merge r4p0 and fixed gralloc from Nameless/Hardkernel to Omni. This could possibly resolve performance and tearing issues on AOSP, though not as good as the Insignal merge I attempted earlier this year (although Insignal used r3p1 blobs that may be far inferior in perfomance than r4p0, so maybe it's better after all). Nameless merged it only on 4412 devices, but I don't see any barrier for our 4210 devices, so I'll try anyway. :fingers-crossed:

r4p0 is very unlikely to work on Touchwiz as the blobs target KitKat. r3p2 blobs target 4.3, and r3p1 target 4.2 but I workarounded it.
I've tried to compile by cherry-picking this commit: https://github.com/ArchiDroid/ArchiKernel/commit/635021e4fdb11d59a8d96948ddd2054d75afdcd4 + added blobs in device.

Everything is compiled properly. But it seems I get stucked in bootloop (SAMSUNG logo bootloop, not even in ROM bootloop) :( No access to adb and I don't own a serial cable. :( Maybe this is useful for you. :D

I already have that installed for a long time, it doesn't affect my CPU temp when playing HD games, it's just that the game I'm playing is really graphic-exhausting, thus extreme temperature rise. Hoho
You might want to try underclocking and/or undervolting the cpu. That seems for my experience to be the best way to avoid the thermal limits.

Hmm, I thought the kernel itself was already undervolted? I don't have any experience in doing UV, now I'm nervous. Haha

EDIT: Okay, I undercvolted my device, I'll try to assess my device for a couple of days first, by the way, here's my CPU voltage table:
1400mhz 1175mv
1200mhz 1100mv
1000mhz 1025mv
800mhz 925mv
500mhz 875mv
200mhz 850mv

I hope this can resolve my heat throttling issues, I'm so amazed with this Kernel, especially the 60hz screen panel, I can't find other Kernels with the same features. Haha!

When I ported r3p2 drivers, the GPU voltage table was missing for 4210 devices. Same here.

Will look into another option, setting upper limit of cpu to 1200 or 1000 will help. I read this somewhere (don't remember butt I'll look into it) and it won't affect performance. Gpu will do the job.

I had some distortions in Gallery while browsing for photos. Sometimes the text had weird characters. Seem to happen only with Gallery in particular.

JZO54kLT5 or something

thx.

Okay, I'm doing my best to not to ask this question, but my sister is bugging me the whole day and told me to ask you this, I'm sorry in advance. She's persistent because she wants a better gaming performance. So the question is:

Is there any chance of having an OC version of GPU (160-267-400)? Or maybe something like forest's (includes OC CPU&GPU) but with r3p1 + 60/62/64hz features for TW in the near future?

My sister saw the performance of r3 for TW in my note. She was amazed by the awesome 60hz feature, and it piques her interest.

PS: Please don't get mad and don't get me wrong, I'm just asking. :angel: More power and many thanks. :eek:
