I am still trying some UV settings that have some impact without causing stability issues... will enter my settings tonight if stable till then...

However ...how objective is that?:

-Not every Samsung device is the same, unhappily; some devices can be more undervolted than others, without getting stability issues...it's a Samsung thing...

- The more un-experienced users play with UV, the more reports about "reboots" you gonna get, without them even trying to reset those settings, before reporting....that's the way things are, but all that cluttering are a drag...

Anyway I'll start entering tonight.....

Btw, it will be fine to have a feature in STweaks allowing users to save different OC/UV profiles/settings

[Galaxy Note II Original Android Development] SirCanealot:
I've had two Note IIs (one white and one black) and both did 1800 at around 1225mV (I think this one might be 1250, but need to do more testing). So I've been quite impressed compared to my SGS3.

I hate stress testing as it never seems to find a stable voltage for me. So I just pull a small group down by 25mv and see if it's stable for a day or two...

While we're on the topic, do we think Stability Test is fine to use? Or is there something better? I'd like to have this done for Andrei sooner rather than later :)

Just want to share my cpu UV.. im using it for 5 days and I can say that it is stable.. I sometimes switch the power saver on and play nfs most wanted and it works great

Nope, looking for analog, not digital... Let me clarify...

For lack of finding a better thread right now, check this http://xdaforums.com/showthread.php?t=1321491

The thread is about a DIY car dock cable with built-in analag audio-out splitter, but these cables are available for sale (well, at least without the resistor part). I have an old Motorola cable that worked great on my previous phones, but it doesn't work on my AT&T Note 2. Did some research and found that while the Note 2 itself is capable of passing through analog audio (some users with other carriers reported it working), it is disabled in the stock AT&T kernel along with the support for the car dock resistor detect.

I know that the car dock mode is enabled with the Perseus kernel, but have not seen anything about the audio out. Can anybody confirm that it is or isn't?

Thanks!!

I had my Note reboot again today, it's probably been at least a week or more since a reboot. Again I wasn't doing anything, just walking around and heard the boot animation sound play in my pocket. Anyway I pulled the last_kmsg file, but I couldn't remember what I had to pull until I looked it up. This was around 10:55. The phone rebooted back around 8:35-8:40ish. So I don't know if the last_kmsg file is usable for my situation? I'll post it here anyway. If it's not usable, if I encounter again I'll grab it right away. Anyway my setup is stock Note II Poland(4.1.2) firmware, using 29.1 completely as I flashed it. I haven't edited any settings in STweaks. I have some Samsung stuff frozen, GPS turned off. Just mobile data was active and I was in an area that doesn't always have the best signal.
[Galaxy Note II Original Android Development] AndreiLux:
last_kmsg contains the kernel log up until the last reboot, so it doesn't matter how long after the crash you retrieve it as it won't be changed or lost unless you reboot again, making the current log overflow the log buffer and kick out the previous boot, or pull the battery inbetween.

In your case it's again the CPU failing to enter or leave low power mode. I have a suspicion that it is caused by a mistake I made (very early since I released the kernel at the beginning) related to overclocking and some voltages. I will fix that in the next version for sure, so I hope it's that which is the cause of some of people's reboots.
[Galaxy Note II Original Android Development] duowing:
Well glad to hear that I could at least provide some info. My reboots have been few and far between. So it really hasn't been much of an issue for me.
[Galaxy Note II Original Android Development] :
Waiting for the next release. The 29.1 is working flawlessly.
[Galaxy Note II Original Android Development] skourg3:
I've had two reboots in about a week on my Verizon Note II. I was traveling when I got the first one and so couldn't pull a last_kmsg for you, but I got one this time. Running on the stock settings from the kernel flash, no changing stepping or voltage in STweaks, stock clock speed. For what it's worth, both seemed to happen when locking/unlocking the phone.

Hope it helps!
[Galaxy Note II Original Android Development] yahyoh:
Andrei do u think it's problem with senosrhub firmware ? :rolleyes:
[Galaxy Note II Original Android Development] AndreiLux:
For that guy, yes.

The new drivers for the next version have an added spinlock on a list operation in that code section so maybe it fixes that problem.
[Galaxy Note II Original Android Development] honki24:
Question, does the kernel handle the gyro/accel/magnetometer hardware inputs? My compass constantly jitters while I'm stationary and jumps very badly while moving. This messes up my navigation and ingress. After some research it looks like this problem goes all the way back to sgs2. Seems the best info I could find was here:

http://xdaforums.com/showpost.php?p=16668543&postcount=19

See YouTube link to visualize what I'm seeing. This issue exists on Perseus and stock kernel but I was hoping Andrielux might have some thoughts on tempering the magnetometer with the gyro or applying a universal (configurable) filter.

https://www.youtube.com/watch?v=h8N9r8Mn8gU&feature=youtube_gdata_player

Note that in the video I'm moving in my car at the beginning and the readings are crap. At the end I come toba stop and the readings just jitter.

[Galaxy Note II Original Android Development] AndreiLux:
On the S3 we could do such a change with some effort, but on the Note 2 the sensors are handled by a separate microcontroller and the firmware delivered by the kernel to it is in binary form so there's no reasonable way one would even begin doing such changes. Sorry.

[Galaxy Note II Original Android Development] betoNL:
Just to inform that I cannot reproduce this issue

I use onboard gps nav progs almost on a daily basis (iGo and Sygic) and tools like gps status, turbo gps (excelent) and gizmos

Could that be , in your case, hardware defect ?

I would consider this possibility if I was you.

Any plans to integrate an Ext to Internal SD Card Swap in the Kernel?

At the moment I'm using Perseus on the N7105, with the Directory Bind app to achieve a similar effect but It would be nice to have it integrated at a lower level.

Keep up the good work :good:
[Galaxy Note II Original Android Development] AndreiLux:
There's nothing for me to support. You can do that per init.d scripts.

If you're talking about the security fix, it's already included here. Their fix acts exactly the same as mine on the outside.

If you're talking about the alleged sudden death fix, 1) Are Note 2 users even affected? 2) We don't know if it is a kernel fix or if they did something in the booloader or TrustZone binary.

If they did a fix in the kernel for the SDS then this kernel won't have it until I can get my hands on newer sources, if not, and it's BL related, then you can flash it without any issues.

Did the Note 2 even get an LLA equivalent update?
[Galaxy Note II Original Android Development] Nathalex27:
Thank you for a wonderfull kernel.

I love overclocking and this kernel is perfect for it.

Batterylife here is 2 to 3 days normal use.

Facebook, lotsa whatsapp and xda. Some calls little gaming like 10 minutes asphalt 7 per day. Just a race.

1800 cpu gave me 4700 approx in antutu latest.

800mhz gpu gave me 5700 approx over 1350 stock ! Antutu latest. Thats just crazy..

(Getting there with some undervolting took about 25 antutu runs.

After a day now 15.5 hours I got 34% battery left. Awesome. Note 1 battery would have died allready 4 sure )

Just io is low. I get 800 and it's keeping my end score @ 20025.

Stock is around 1300 so bloody awesome but top ranking note 2 has 2600 something....I want that. Thats just....

Could you implement @ 2000mhz cpu step and is there a way to up the io throughput and what is the best io scheduler for benchmarking and read ahead setting?

Loads of questions but I'm just an enthousiast enthousiast...

Thanks in advance and keep up the good work.

Other than the occasional reboot every other day ( like once in 2 days stock kernel settings. I overclock for bragging rights not 24/7 use ;) ) this kernel has been good to me.

Anyone use System Tuner Pro to tweak the cpu, rather than using Stweaks?
[Galaxy Note II Original Android Development] EdgaBimbam:
stweaks gives more advanced cpu governor tweaking rather than system tuner. I prefer stweaks ;D but you can also tune with system tuner, no difference
[Galaxy Note II Original Android Development] betoNL:
Yes...this or android tuner beta

On both you can save different undervolting profile settings, and that's very handy for testing purposes, special when switching kernels

EDIT: I don't use one rather than other...I just use both, since both got some different stuff...

Complementary....

i using setcpu...
[Galaxy Note II Original Android Development] CekMTL:
Well ... haven't had your scare (for now) questionmark... hopefully never! :confused:

Battery life is exquisit, the best I have ever seen, with my usage pattern... yesterday with all the back n forth testing, I clocked almost 8 hours screen, and something like 6 hours usage of StabilityTest, heheheheheh legendary! xD

Charged it again (this thing charges FAAAAST with 2A), started using it again @ 99% for "light browsing in bed" and then I noticed I spent one hour browsing, and batt was at 92%.

Went to sleep and woke up 6 hours later with 91% left... woooooot! xD Before it would drop 1%/hour easy!

Got to say, that after these insane 600mV I limited off screen to 200-700 with SetCpu... sweet deal no hangs, no SOD, no nothing except sweeeeetnessssss :))))

Thank you all!

BTW: Thanks to all those kind enough to thank me for my "scherlock holmes mad professor work", and even the legendary Chenglu thanked me, hehe :D

Well... you need root to do almost anything "fun", so anyhow the answer should be YES! :p (technically you could use ODIN, and bla bla bla, but what's the point if you can't tinker with anything...?)
[Galaxy Note II Original Android Development] lycan_codex:
Which app should i use for gpu overclock ?
[Galaxy Note II Original Android Development] D3_:
My phone is really weird I guess.

800mhz @ 925mv

900mhz @ 950mv

1000mhz @ 925mv

and below that it's all 600mv.

If I even try putting 900mhz @ 925mv the phone will freeze instantly, but 1000mhz can handle stabilitytest at 925mhz just fine.
[Galaxy Note II Original Android Development] kobebb:
same here, but what about 800mhz? i can even use 600mv.
[Galaxy Note II Original Android Development] CekMTL:
Hehe, not in my case xD instant freeze! .p
[Galaxy Note II Original Android Development] kobebb:
Omg... thats strange. i just wrongly changed the 800mhz instead of changing 700mhz to 600 mv.. haha.. A big discover:fingers-crossed:
[Galaxy Note II Original Android Development] AndreiLux:
I want to ask again, does it run at higher voltages? I.E. if you're "running" 700Mhz at 600mV, please test it at 700mV or 650mV. I don't want it to be some placebo effect due to the regulator behaving funny at 600mV or similar and the real world voltage not really being that. I just can't believe the voltages, we're running into physical near-threshold transistor voltages and a tweak in the manufacturing process just cannot bring this decrease in leakage. But in terms of the software there is no error in the code...
[Galaxy Note II Original Android Development] agentdark45:
Well, I stress tested 700mhz from 900mV down to 600mV in 50mV increments using SetCPU (performance governor) using stability test and no probs whatsoever over here!
[Galaxy Note II Original Android Development] AndreiLux:
I'm going to review the REV_2.0 specific code again and see if they introduced something funny in it, but if not then.. well good for you guys.
[Galaxy Note II Original Android Development] CekMTL:
Can reply the same... tested all the way down to 600 in -25mV steps... all peachy, so or it is an amazing CPU or there's something funny going on! ;)
[Galaxy Note II Original Android Development] AndreiLux:
I think I found the fishyness:

if (soc_is_exynos4412() && (samsung_rev() >= EXYNOS4412_REV_2_0)) {
tmp = (is_special_flag() >> ARM_LOCK_FLAG) & 0x3;

if (tmp) {
pr_info("%s : special flag[%d]\n", __func__, tmp);
switch (tmp) {
case 1:
/* 500MHz fixed volt */
i = L11;
break;
case 2:
/* 700MHz fixed volt */
i = L9;
break;
case 3:
/* 800MHz fixed volt */
i = L8;
break;
default:
break;
}

pr_info("ARM voltage locking at L%d\n", i);

for (tmp = (i + 1) ; tmp < CPUFREQ_LEVEL_END ; tmp++) {
exynos4x12_volt_table[tmp] =
exynos4x12_volt_table[i];
pr_info("CPUFREQ: L%d : %d\n", tmp, exynos4x12_volt_table[tmp]);
}
}

This is something specific to the REV_2.0 chip, and apparently it locks the bottom voltages beyond a certain frequency level.

Can somebody provide a whole boot sequence kmsg please?

Edit: This still doesn't change anything beyond the definition of the stock voltages... hrmm.

[Galaxy Note II Original Android Development] CekMTL:
Yep I think the same... must be presetting some bootup stuff... as if I input 800@900mV it works peachy, but if I do 800@875mV it instantly freezes... so it means it is truly changing the vcc..

A guy here says that he can run 800@600 ... so, maybe with a little bit of luck it will turn out to be true that this soc can run with lot less juice ;)

Anyone tried using the allshare cast dongle with this kernel?
[Galaxy Note II Original Android Development] EdgaBimbam:
As i know to use allshare cast u need to have flash counter 0, with custom kernel or recovery flash counter is always minimum 1. So it shouldnt work
[Galaxy Note II Original Android Development] Conan179:
and waht is with triangelaway auto restting on boot?
[Galaxy Note II Original Android Development] EdgaBimbam:
Dunno what could be with that feature. But i think it wont work. But if you have possibility to try, then try and leave feedback. Im also interested about allshare cast dongle but i prefer more perseus kernel and its feature :)
[Galaxy Note II Original Android Development] betoNL:
How do you see the counter ?

I have everything custom and I never had triangle once

Never had on the Note1 neither on the Note2

I thing it will depend on how you root your phone .... I guess ...

However I dont have the dongle yet to test that allshare thing

Of course you can keep root on stock

Just use the GNote2 ToolKit for all your rooting needs; you will get the insecure image, root, custom recovery and much more, without raising flash counter and stuff ...
