Alright so here's the first release of this kernel for codeworkx's CM9 with hardware acceleration.
Again this is for codeworkx's cm9.
Also, this is for codeworkx's cyanogenmod 9.
One more time, this is for cm9 only.
Finally, this is for cm9 and cm9 only!
Don't let the "alpha" title fool you into thinking it's not stable... it is... It's only alpha because it's still in the "testing" phase.
FEATURES/CHANGES
Overclockable to 1.38GHz
Underclockable to 150MHz
GPU overclocked to 384MHz (highest possible without bottlenecking and battery waste)
Tuned OnDemand Governor (recommended)
Interactive Governor with time view concept (learns from your use and adjust parameters accordingly)
Wheatley Governor (optimized use of C4 state)
Hotplug Governor (turns of one of the cpus to save power when load is very low)
Pegasusq Governor (A better version of Hotplug, but experimental and not designed for our devices)
SIO scheduler for speed/performance with flash storage
Linaro Toolchain
Linaro optimizations and patches
Linaro makefile compiler flags
Makefile Optimizations to boost performance
Optimized CRC32
Optimized ARM RWSEM algorithm
Tiler Memory increased to 32MB (linaro)
Other Tiler patches/tweaks to improve 2D gpu performance
SLQB allocator

lib/memcopy use glibc version for speed
lib/sha1: use the git implementation of SHA-1 and removed ARM sha1 routines
I/O backport from 3.2 linux kernel for less dirty throttling
Tweak CPUIDLE to enter deep sleep faster thus saving battery
LowMemoryKiller backported from 3.4 kernel
Disable GENTLE_FAIR_SLEEPERS for improved performance
Allow Deep Sleep to occur when media decoder is active allowing the cpu to shut off when playing music or video.
Allow MPU logic to power down when in deep sleep to save power.
Increased default readahead value to 1024KB for faster sdcard reads
A lot of stuff I probably forgot I did.
Also includes a ridiculous amount of bugfixes, patches, and tweaks that can found on my github commit log.

DO NOT, UNDER ANY CIRCUMSTANCE, USE SETCPU PROFILES OF ANY KIND OR ANYTHING SIMILAR WITH THIS DEVICE. Things like screen off max frequency, temperature throttling, and others are already built in to the OMAP architecture. Using ANY profiles will ONLY lead to problems, instabilities, and battery drain.
***************
Let me know how it "feels" especially by default without overclocking or underclocking. Also I'd be interested in how the battery treats you. Thanks!

Which boot screen. I think I know the issue if its not the cyanogenmod one.
Sent from my GT-P3113 using xda premium
I have this issue too and it's the Tab2 10.1 screen. (the first one that shows during boot)
It's the Tab 2 Splash screen. I can adb, go into DL, and get into CWM so it's fine... it just won't boot.
Yeah its probably because I forgot to use the 10.1 ramdisk. I'll upload a fixed version shortly.
Sent from my GT-P3113 using xda premium
No worries man.
Thanks for getting started anyway, a lot of devs can use your fork now.
New version up. In addition to some bugfixes and reverts, this time the espresso10 ramdisk is actually used instead of the 7 inch version
Now it installs fine. What app should I use to control it? NSTools, Voltage Control, CPU Master, etc...

Glad to hear it. Let me know how it runs.
Really doesn't matter what you use as they all modify the same sysfs entries. I like no frills CPU control because its simple and only does what I need it to do.
Sent from my GT-P3113 using xda premium
Changing OC settings with NSTools or CPU control causes reboot. Settings don't change.
I can change min freq and governor (tried it with interactive and wheatly), just not max freq.
Works like a charm now. I'll keep you up to date on performance once I've done some testing.
Works fine in voltage control, and stable at 1380 so far with little heat. I haven't really stressed it though but it does run smoother and more responsive than before. The GPU seems snappier too. Great job.

Can you post a complete "feature list" with next version ? Oh, and can Voodoo sound be integrated for better (sound) quality ? I'll keep pressing the thanks button.
Thanks for the kernel, will test it later this day.
Maybe you can add an how to flash guide for the n00bs who want to flash but don't know how to do it?
works works works!!!!!!!!!! like an awsomeness thing! hehe i know that i can trust on you m8, but i did ask for it..yet and you made it! thx really THX!!!!!!
Hi,
Thank you for work but is what I am to have a problem of hangs and of connection with WIFI
Been testing the kernel with default settings for some hours now ... started using it since 11.oo this morning and started with a full battery. After playing some games (tablet/battery temperature stayed normal) and browsing the net, checking emails and some more stuff i must say the kernel works smooth and my tablet runs faster. Am using the kernel for 3.5 hours and the battery is at 71%. No weird things happened so far. WiFi and bluetooth both work fine in other words...
the kernel feels goOOOood

FAQ
Q. My phone is running hot!
A. This is usually related to the voltage being too high. Try lower voltage, and try to determine which frequencies are running hot for you. You may need to also restrict your max CPU frequency with SetCPU, System Tuner, Kernel Tuner, etc, if the frequency won't run stably on your phone.
Q. CPU-intensive apps (particularly games) terminate abnormally after a bit of use.
A. This usually means the voltage is a little too low for that frequency. Try to raise the voltage (only 12.5mv at a time) until you find a stable voltage, and let the rest of us know what value is best for you.
Q. My phone won't even boot with this kernel.
A. Sounds like the voltages are too low for you. Try the "STD" version, which uses voltages only slightly lesser than stock.
Q. I want GPU overclocking, but I don't want CPU overclocking.
A. Use the "OC" version, and use SetCPU, System Tuner, Kernel Tuner, etc, to set the max CPU freq you want.
Q. Proximity sensor doesn't work during a call
A. Fixed in version 0.4
How stable is it?
And also, if I read/understood the "main features" right, you limited the CPU to only use 2 cores instead of 4?
I read that you did it for more stability when overclocked, but if this only uses 2 cores out of it's 4, I will be very hesitant to flashing it...
Either way though, this is great progress! We are finally getting a handfull of developers for the Padfone 2! Hopefully we can get Cyanogenmod ported soon aswell!
Great job!

I've been using it for a few weeks, and when I had 4 cores enabled, I found it a bit unstable. With 2 cores enabled only, it flies along due to the higher frequency, and is rock-solid.
Unless you're using the MSM_DCVS Governor (which isn't default even on stock kernel), not all the cores are used except for under high load. Using Interactive, Performance, and other Governors, it usually keeps 3 cores off, and just powers the second one up when doing things. Only when running very CPU-intensive tasks will all 4 cores be used, and the phone will run very hot. If using the MSM_DCVS Governor, it'll continually lower the CPU frequency anyway. These factors are why I've limited the CPU cores - the end-result is a faster, cooler, and less power-hungry kernel.
Nevertheless, I'll upload another one in the next couple of days with all 4 cores enabled, so people can test it out.
First of all nice work here ! Good to see people progressing. As im still bit of a noob and my question maybe quite noobish.
I have NOS installed on my padfone 2 atm and its working flawlessly. Just before I try this I wanted to ask you if this will some way interfere with NOS ?
I would happily be our test monkey if needed
One more time,
Thank you !
Hey first of all this is very nice that you develop kernel to padfone and its nice to see some progress , but i would like that if you make the kernel with 4 cores and little bit smaller clocks ex 1.5 or 1.6 and if you set low freg to somewhere near 100mhz. That would be nice to see

Quad core
I've recompiled the kernel with all 4 cores enabled, and will update after I've done some stress testing. (I won't upload it if it's not stable for me.)
When I tested it a few weeks ago, quad core was too hot, but I've tweaked the voltages quite a bit since then, so hopefully it'll be upload-worthy.
How to download link using phone?
Quad core version uploaded
I've uploaded the Quad core version too.
Curious to here other people's experiences on that - I personally find that my PF2 barely uses the 3rd & 4th cores (even on stock kernel), so I prefer the dual core kernel version (faster, more stable, less heat, less voltage requirements), but CPUs differ a little from phone to phone.
Keen to here people's tests from the dual core kernel vs the quad core kernel.
Me currently testing dual core version
Just downloaded and installed the QuadCore version. Will be back here in a couple of days!
Can you say thank you too many times ? NOT!
Thank you once more !
Thank you for quadcore version wil try it out!

Reboots in Padfone Station
I tried to use the dual core version today during some meetings and it was fine when in phone mode, but after using it in the station for a while it would get very hot and then reboot. I was overclocking it to 1.7. Anybody else have similar experience?

Usually "very hot" means that the voltage needs to be lowered. Can you try using System Tuner to lower the voltage slightly for 1.7ghz frequency, and advise whether that helps?
i have flash the dual core ver.
But when i boot and at the asus loading logo, it keep shining white screen and some color line.
After booted into system it soft reboot again and again. then i revert to stock kernel it fine.
i already wipe cache/dalvik
i am using TWRP 2.5 and stock rom
Undervolting 1.7
I have not tried it in the padstation yet, but the 4 core version undervolted 1 step down (1125 I think?) was stable when I just played Final Fantasy 3 for about 20 mins. CPU spy shows that it was running at 1.7 during that time. No apparent heat issues and no reboots or anything like that. I will try it in the padstation and report back later.
---------- Post added at 03:49 AM ---------- Previous post was at 03:40 AM ----------
Just to be clear I only further undervolted the highest frequency (1.7). Other parts of the table were default for your 4c kernel.
Which app is recommended to overclocking and undervolting?
Hello,
Let me introduce a kernel that I've been using every day. Despite the name which is me, the actual developer of this kernel is aatjitra, so please thank him. Since he is using N7105 and for ease of reports, we decided to make a separate thread for the International Samsung Galaxy Note II GT-N7100 model. So it is me that will maintain this thread for N7100. Of course with the help of him to answer questions.
For GT-N7105 model, please visit the original thread here
* WARNING *This kernel is only for stock ROM or TW Based custom ROM!DWYOR - Do With Your Own Risk!!!
TerraBuzz kernel is created for Samsung Galaxy Note 2 that will suits daily usage. There is no cutting edge and fancy development for this kernel as it's made as close as stock kernel based on source code provided by Samsung. Only cherrypick modification/enhancement from other developers to be implemented in this kernel. This kernel is fast, stable, and battery friendly. All tweaks and modifications are carefully tested to ensure great performance without compromising Galaxy Note II standard features.
Some unnecessary debug and log is also removed to make this kernel as light as possible.

Screenshots
Here are some screenshots collected from some of our users in the development of this kernel using various ROMs. Please use it as reference only, actual experience and results may differ.
TerraBuzzQ CPU Governor (Suspended)
I tried a few CPU governor which can suit my preferences that will turn off CPU core if the load is light to save battery.
And I come to LulzactiveQ by Tegrak that initially I think this is suitable for me. Nobody is using this governor for Note 2 and I dare myself to try it on my own.
Later on, I modified the source code for LulzactiveQ to remove some parts that I don't need and create my own logic for this cpu governor.
There are 3 thresholds for CPU load:
High Threshold = 100%
Up Threshold = 60%
Down Threshold = 30%
If CPU load = High Threshold (CPU Load = 100%)
CPU scaling per 200 MHz until it reaches maximum frequency 1600 MHz.
If Up Threshold < CPU Load <= High Threshold (CPU Load between 61% and 99%)
CPU scaling per 100 MHz until it reaches 1400 MHz and stop at that point.
If Down Threshold < CPU Load < Up Threshold (CPU Load between 31% and 60%)
CPU scaling per 100 MHz until it reaches 1200 MHz and stop at that point.
If CPU Load <= Down Threshold (CPU Load less than 30%)
CPU down to lowest frequency 200 MHz.
By this logic, TerraBuzzQ Governor suits my daily usage pattern and tested by beta tester team. The result is great battery life and no lag encounter in heavy game such as Real Racing 3.
Finally, it's available in XDA...
Best kernel i've tried so far.. Battery friendly yet very smooth...
Thank you for helping me TerraBuzz...

The best kernel for me
I have tried all of kernel.. This kernel is so smooth, but with battery so much friendly..
Thx for aatjitra.. :good:
this kernel can run on aosp?

does it support CRT off animation, that it stopped after flashing this amazing kernel,
not a big issue compared to its smoothness
thanks

Gona try this kernel. Been using neak kernel for sometime and its really good. But whenever I start to play games such as real racing, I get huge battery drain. Duno if its normal or its really a kernel prob. xD anyway will try this one and report back.

Hi guys please post your custom kernel setting with highly battery life and cool temperature

CPU governor - intelliactive
Disable MP decision and enable Intelli-Plug
Set multicore power saving to 2
I/O scheduler - cfq
If you don't want high graphics then reduce the GPU frequency and similarly if you don't want smoothness them reduce CPU frequency
I personally don't advise settings CPU profiles as they make the phone lag a lot!
Hit thanks if it helped!
Hey guys,
I have made this thread to post results of vigorous study, research and experience in order to achieve a perfectly tuned kernel...
I have spent many hours finding what each of the available option in stweaks are for and have studies in detail about what each setting or governor is good at or built for....
I learnt this from many information threads available on xda (Reference links for those threads at the end of post)...
First of all you need to be rooted and need a custom kernel like Kushan Kernel, Imperium Kernel etc which support Stweaks settings so you can change governor, frequencies etc...
So basically there are three types of Rom users. (according to me )
Who like performance and want a snappy experience not caring about battery life (Me included )
Those who don't care much about performance and care very much about the battery life and SOT they get
Those who like a mixture of both (Some performance loss for them is okay)
First of all I not responsible if anything happens to your device or if a ghost attacks you or even if you burn down your house
Okay so below here are the settings which I have researched a lot and personally tried (obviously your experience may be different)
The data below is more based on research than on practical test (though it has been tested)
Best Settings for I9505 (May or may not work on other devices)
----------------------------------------------------------------
CPU GOVERNER:
Performance -> Interactive
Battery -> SmartMax, Ondemand
Balance -> Interactive, YankActive
Gaming -> Interactive
----------------------------------------------------------------
HOTPLUG:
Performance -> MPDescision, Intelliplug (Performance)
Battery -> Intelliplug (Conservative)
Balance -> Intelliplug (Balanced, Eco Performance, Eco Conservative)
Enable TouchBoost
----------------------------------------------------------------
GPU GOVERNER:
Overall -> Simple
----------------------------------------------------------------
I/O SCHEDULERS:
Performance -> FIOPS, Noop
Multitasking -> BFQ, CFQ
Battery -> Noop, FIFO
Balance -> SIO, ZEN
Internal Storage Read-Ahead:
Stability -> 128kB
Balance -> 1024kB
Performance -> 2048kB
SD Card Read-Ahead:
If Size of SDCard is (Card should be of good quality if not branded then use 128kB)
Less than 8GB -> 128kB
16 GB -> 1024kB
32 GB or more -> 2048kB
----------------------------------------------------------------
MISC:
Android Logger -> OFF
zRAM -> OFF (Only keep it on if you are heavy multi tasker or play heavy games)
Swappiness:
Smooth Operation -> Between 0-50% (Ideal 20%)
Heavy Gaming -> Between 50-130%
TCP Congestion -> Westwood
Dirty Background Ratio -> 5%
Dirty Ratio -> 20%
VFS Cache Pressure -> 100%
Dirty Expire Centisecs -> 200%
Dirty WriteBack Centisecs -> 500%
---------------------- THATS ALL FOLKS -----------------------------
I would like to thank xda and few other sites for all the research I could do.
Here are some threads if you want to go into detail how I found my conclusions

Nice thread brother, thank you!
Hi @Kushan02,
thanks :good:
Hi @Kushan02
How did you set the default kernel (on your rom)?
cpu is intellimm, gpu is ondemand, not those on 1st post
thanks

Thank you... but I talk of the default settings. Are those the stock kernel?
Notably, there's lags
I just changed with the proposed settings 1 post, and it's better

Hi,
No, I had lags with default settings but with those of the first post, it's better!
You said there are 3 type of users (1,2,3)...
Those settings are for?
I want the best battery life without have a really bad performance.
Thanks
What about settings regarding undervolting our device? I asked at Kushan Rom thread, but maybe it is more appropriate to ask here..
Thanks my friend. I will try this setting as soon. I think that you are able to compile "presettings" like:
Long battery use (settings for a long duration of battery charge)
Performance (settings in this post)
Game boost (setting for game use)
Etc...
I hope that i give you an idea.
Thanks a lot
