[OVERCLOCK] [3-7-2012] dagkernel 0.2 CPU/GPU Overclock up to 1.94GHz

So let me make sure I understand you right...if we get some other devs besides Da_G to work on the kernel then my antutu score will go up from 7788 to 10,124?And my battery would only drain .8% overnight instead of the 4% it drains overnight now?
I dont wanna clutter the thread with argument like responses to your sarcasm, but since you seem to be in great disbelief - I'll respond to few points you made:
1. Antutu scores is a combined measurement of many benchmarks, which include CPU, IO, memory, various graphics performance parameters etc'. Not all of these are used frequently during normal phone's operation. Therefore Antutu score may be greatly impacted by a benchmark, which in reality uses only 2% of the CPU cycles, or vise versa. Speaking from experience and coming from years of using other android phones I did see things like IO schedulers, for example, give noticeable boost to performance, which may not be visible using a benchmark tool, for the reasons I just mentioned.
2. Battery drain isn't going to be reduced by half by using a smart algorithm, such as hybrid adaptive voltage scaling (HAVS), but it might achieve results close to that, if combined with trickle charging mod, which charges your battery to a full, not fake 100%, and can keep your battery at 100% charge for nearly an hour after it's unplugged and phone being used.
If you want to get autographs from people, who made those amazing kernel mods possible - you can start with netarchy , toastcfh and some other devs from Team Win gang, who made amazing things like hardware acceleration based HDMI mirroring possible

Long weekend.. working on a new build now
HAVS is actually already built into the stock system. It scales according to demand from 3 separate units (the memory/bus subsystem, the GPU, and the CPU(s) )
The voltages you can set in system tuner/fauxclock/etc. only apply to the CPUs, once my app is out you'll be able to adjust GPU and L2 voltages/speeds as well.
The other governors etc. are coming shortly.. hopefully tonight

It's a blessing to have you onboard. Just bought you a beer: 3UH01598G2087792E
Next time maybe I'll take that 1 hour drive to OC and buy you one in person

I was just about to ask where you been brudda. Can't wait for a fully made kernel by you

Awesome work Da_G! So the new kernel will enable Voltage Control options for Antutu's CPU Master Pro?

Da_g so if havs is already implemented in the stock kernel, then if we statically undervolt the cpu does that mean it won't use havs? and then would it be better to not undervolt at all or does undervolting just limit the max voltage that havs will use?
thanx
thanx
Great question, I was wondering the same thing what would happen if you use an app like Antutu CPU Master to force static undervolting on kernel with HAVS. There is no doubt in my mind HAVS is better than static undervolting for a number of reasons, with stability being #1, but I'm also curious to know how such conflict would be handled.
Are you sure you didn't mess with voltage settings and do something wrong there? Happened to me one time and started acting the same way you described yours. Anyway good luck

That settles it. I was gonna flash but now will wait

I have a question. I flashed your other rooted kernal (the non OC one), but now I want to flash this one. Can I just flash this one over the other one without resetting or anything?
wipe cache, dalvik cache and disable any CPU control apps like SetCPU or Antutu CPU Master and then flash the new kernel on top of the old one.
Why am I so anxious waiting for this update? This is ridiculous.
Thanks for the work you're doing for all of us. I just jumped over from the HTC scene (Evo 4g & Evo 3D). I was a little worried about the developer scene on the Samsung side of things, but having a working root, OC kernel, etc at the time of launch is great! And now CWM is up and working, I couldn't ask for more.

Thanks for your hard work.
Thanks for all you've done so far. Really looking forward to the update.

So color me retarded, but after I flash the kernel via odin, when I go to push the libs to the phone, adb can't see my device. I get "error: device not found"
...My apologies if this has been covered somewhere, searching didn't give me any answers.
EDIT: Nevermind, must either be a Windows issue or a driver issue (yes I have the Samsung drivers from the OP installed). Rebooted to Ubuntu and ADB is working fine there, so whatevs, it's working somewhere at least lol. Just one more reason I rarely use Windows these days. Anyone know if Hiemdall will work with the Note? Would be nice...

Can you now push over the libraries via cwm? Sorry for the noon question.

+1
I appreciate all you do Da_G
is there any reason why i would only be seeing 1512MHz in setcpu? I have followed all of the instructions to a T. Should I not be using setcpu?
Good question.. I switched over to AnTuTu CPU Master Pro when I got this device because it seems that's what most people are using for it. I haven't had any issues with it.

132So, this doubles as a root kernel (might as well keep the scripts in there since I already made 'em!), custom boot animations (/system/media/sanim.zip), init.d support.
Max speed is 1.94GHz. Max speed I've benchmarked stable at is 1.83GHz. Reboots at higher.. YMMV with voltage adjustments etc.
Stock speed on this kernel is 1566MHz, I have removed a lot of scaling overrides that Samsung added, so this should be a bit smoother than the stock kernel without OCing more than the slight default.
GPU is also OC'ed from 3d speed 266 -> 300 and 2d speed 200 -> 266.
I will be releasing a GUI soon with more advanced tweaking options for the kernel (it is compatible with existing tools like system tuner, fauxclock, setcpu, etc.)

Don't forget the donate link in my sig if you find this useful13I never learn my lesson about providing an ETA, keep slipping! I've got BFQ, CFQ, smartassv2, etc. etc. in now, just dotting some i's and crossing some t's.. coming soon! Lowered some default voltages on the higher end of the scale (1.89+) also since some people have reported stability at lower voltages at those speeds.12sgs kernel flasher will work if it read/writes to mmcblk0p8 (which is where the kernel lives on our device)
