Yep, pretty darn sweet. Also got just under 20k on antutu.
Thanks for the awesome kernel!

Is there anyway to go back to a stock kernel aside from the following:
-nandroid
-reflashing the original ROM
Because I am a second away from flashing this kernel but would really like to know how to return to a stock kernel aside from the aforementioned methods.

There's a kernel in android development section. (Sorry for not posting link) in the stock flashable ROM thread. Unsecure kernel and boot animation. I'm sure someone has the stick kernel though. Matter of fact I know someone does. Flash away partner. We'll get you back.
BTW I think, unless put in the script to do so, flashing a ROM doesn't over write the kernel . I could be wrong but I think that's at a different level in the phone.
Yes flashing a rom does come with kernel also.
So flashing 0 will remove the governor tweaks flash correct.

Wiped Cache/Dalvik Cache then flashed Profile 5. Whatever benchmark I use auto quits. Seemed to run fine on the original Perseus but not the profiled one. I suppose it could be that my device doesn't like that low of an undervolt, but just wanted to make sure I was doing everything right.
EDIT: Just needed a reboot... for the 3rd time.

yes this means the gpu or cpu are being taxed to hard at that voltage, go up a profile.
or start playing with voltages a bit, if it auto quits but isnt rebooting your phone your at the threshold in where it wont crash but is just starting to fail, when you can compelete antutu everytime then you are probably stable.

Well, i can say for anyone on the fence about flashing this kernel, don't even hesitate -it is totally awesome.
Last night, i flashed it with profile 5. I'm fully capable of doing all the tweaking myself, but it's time consuming as hell and with Christmas coming etc I'm simply too busy to go through the procedure.
Profile 5 runs perfectly for me scoring just under 20,000 in AnTuTu.
After benching a few times, I started running StabilityTest v2.5. I ran both the Classic Stability Test and then CPU+GPU repeatedly and it was rock solid on both.
At the end, I actually fell asleep with the CPU/GPU test running. I woke up hours later with the battery just about to die and the test still running. This was amazing as no matter what ROM/kernel a phone is running or how conservative it's set up, most phone will eventually freeze up stressing it like this.

THIS ^ is why I made these.
If I were to have to start all over again and have no idea what voltages I needed. Id flash my profiles and then tweak more from there.
Glad I could help..
Just noticed something screwy. I took my phone off the charger at 645 this morning and its now 9. It only says I've been on the battery for 32 minutes. I haven't hooked it back to a charger since 645. Any thoughts?
Edit...its in the restart .. Restarting the phone resets the batt stats. Anyway around this? Makes it tough to figure out what kind of improvements this kernel gives.

my friend has an ATT note 2 and he can't use app2sd script to swap storage with this kernel can somebody try this with the verizon note 2 ?

112This 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.
- Application for control of various settings.
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 Verizon variant SCH-I605. Versions for other variants are found in their respective forums.
You obviously need to be unlocked with the "Suck it Verizon" bootloader/IROM unlock method before flashing this. I will not be responsible if you break your device by screwing up anything related to that.36STWEAKS PROFILES! and proper bootloop fix.
Alright! now that Perseus Kernel .28 is out we have a new added feature that lets us implement override profiles!
What does this mean?
Well now this UNCHECK SET ON BOOT zip will actually just update your current default.profile and uncheck the set on boot options.
Which makes it the best fix for a bootloop, because you can then go back in to your old settings that failed and modify them.
I also am going to be generating 5 profiles. (will edit this post)
Each more aggressive overclocking and undervolting.
For people who are unsure of how to do do this properly with Stweaks,
You can just flash any of my profiles.
I recommend you download them all start at 5 and flash, if you bootloop or crash move up a profile until your stable!
Profile 5G is the one I run everyday (and is the lowest values for voltages)
It also is 200-1800 mhz overclocked and gpu 160-640 mhz
My custom governor tweaks (I believe the cpu is too aggressive and also the cores dont respond as much as id like to see them responding, 1 core on idle, 4 cores when needed.)
Profile 5 is the one I run everyday (and is the lowest values for voltages)
It also is 200-1800 mhz overclocked and gpu 160-640 mhz
STOCK governor settings
Profile 4 is slightly less aggressive on the voltages
200-1800 mhz 160-640
Profile 3 is slightly less aggressive on the voltage curve
200-1800mhz 160-533
Profile 2 is slightly less aggressive on the voltage curve
200-1600mhz 160-533
Profile 1 is slightly less aggressive on the voltage curve
200-1600mhz 160-533
Profile 0 is the DEFAULT profile the kernel came with. (it just deletes your profile and rebuilds it so its safe for all versions inlcuding S3-i9000)
EDIT: I have also included a zip with just the governor tweaks, these will not alter your voltages on cpu/gpu and will not change your max cpu
custom governor tweaks detailed below:
here is my logic
defaults parameter mine
30000 sampling rate 20000
82 up threshold 90
5 down diff 10
40% thres for response 81
1200 freq for fast down 1600
95 up thres fast down 98
37 up step 18
6 splice amount 4
13 down diff 8
With the default settings when the load is measured if the cpu load is over 82% off current freq step it will scale up.
New logic added in perseus .27 now gives us 3 up steps instead of just a fixed one.
so your cpu will step up more aggressively based on how much above the threshold it is, not just if its over, this is
great.
Right now, if we are coming in with a
load of 83%-88% we increase freq by 300mHz
if we are 89-94% we increase freq by 400 mHz and
if we are 94-100% then we increase freq by 700 mHz.
This is too fast for me.
For a few reasons the main one being that the amount we jump has gone up because our max cpu is 1800 instead of 1600 (at 1600 the jump ups are 200,300,600mhz)
The logic I use on my N2 is as follows:
Load of 90-94 = 100 mhz jump
load of 95-98 = 200 mhz jump
load of 99-100 = 400 mhz jump
The responsiveness of the phone is not compromised at all, the cpu just steps up less and only when it has really high loads(keep in mind the load is calculated every 20000 microseconds or 50 times in one second.)
It still gets to 1800 and does many operations there, but it comes out of 1800 fast and when it jumps down it jumps down further.
The fastdown has been upped from 1200 to 1600 , meaning it now requires 98% or higher load to jump up when above 1600 mhz not 1200 mhz, I found that the CPU was always in 1800 or like way lower,
never in the 1700 - 1200 range as it used to need 95% load to be in that range.
The cores hotplug has been slightly changed to turn off cores quicker when not in use and takes more samples to turn them on so they only turn on if load exists for longer duration of time.
PLEASE NOTE
Flashing any of these zips OTHER THEN THE UNCHECK SET ON BOOT will REMOVE your STWEAKS settings and replace them with the profile. PLEASE back up your profile if you want to save it.
Where is it?
/data/.perseus/default.profile << back this guy up. rename to default.profile2 works. or copy to sdcard.
Due to the way that these changes are applied (at initial boot) it will take longer then usual before beginning to display the boot animation for the first boot after changing profile.
This also means that you cannot flash 2 of these files in one boot, for example profile 3 and the governor tweaks.
You would need to flash the governor tweaks or the profile first and then reboot, and then flash the other.107How did half of you even manage to unlock the bootloader? I understand some may be uninformed and unfamiliar with the phone or Samsung but then please just read the original thread and the guides in the international forum.
And please stop flashing profiles blindly without even having tried the stock settings or having a lack of understanding what those changes do. I'm not a baboon mis-configuring the kernel with idiotic settings.
I'll answer in the main thread if there are some serious questions...5I just received a PM from a member with a postcount of two which massively pissed me off; and I'll paraphrase the content of it since it's against rules to post PMs:
And my reply which also counts as a little open-letter:Some guy said:
The arrogance, stupidity and sheer ignorance I've met here from members of the North American variants Sprint, Verizon, AT&T, and T-Mobile are magnitudes beyond what we have on the international S3 or N2 forums and it frankly just baffles me. I already stopped replying in these threads here mostly as it's just too annoying.
There's no point in this post other than letting steam off and just a big finger-raiser to people with such attitudes.
