About the issues with Pegasus Prime SOC in Note 2 (gpu glitching/arctifacts/Apps FC's)

After a few days of testing i confirm that the solution adviced by AndreiLux itself works great.

If you experience FC's in graphic intensive apps, or a common glitch which corrupts the screen in a "checkboard" style image, all you need to do is to raise gpu voltages a bit.

As AndreiLux explained, he develops the kernel with his GS3 as a base, which uses a different Exynos cpu revision (1.1). The note 2 houses a new revision (2.0) that has a different clock speed management alongside with other improvements.

Issue:

Gpu fails to up the requested clockspeed in the scaling policy because theres not enough voltage in clock speeds. Raising the clockis from the minimum speed to intermediary then to the max crashes the driver and resets the gpu state. Raising the voltages of the lower clocks fixes the issue. Clocks above 533mhz

are not affected

, althought ive opted to raise them a bit just to play safe.

To fix the general stability issues, open Stweaks and raise the voltages like this:

54mhz: 875mv (was 825)

108mhz: 900mv (was 850)

160mhz: 950mv (was 938)

266mhz: 975mv (was 963)

350mhz: 1050mv (was 1013)

440mhz: 1100mv (was 1075)

533mhz: 1150mv (was 1138) [optional: stock voltage is fine]

640mhz: 1150mv (was 1125) [optional: stock voltage is fine]

---- no need to be touched ---

733mhz: same as stock

800mhz: same as stock

These are fail safe voltages under any circumstances. Note that ive opted to raise at least 0.50 on voltages, but i dont exclude that a 0.25 could lead to same results. So a small undervoltage is still possible.

This issue fortunately is not widespread, only a few users are effected. If you are one of those please take my advice and see if that helps.

Also this method greatly reduces lags when opening folders or when scrolling thru pages.

AndreiLux if you can, please add this post to the OP. Ive discovered that other users suffer from this issue, you can look a few pages back.

It would be ok if you can raise the stock voltages of the gpu with a small 0.25 increment to see if the kernel keeps staying stable out of the box.

Thanks AdreiLux for this fix. If helped, spread the word. I would like to see this post in the OP as i had a very hard time figuring this out.
[Galaxy Note II Original Android Development] AndreiLux:
I appreciate your contribution, but I wouldn't go as far as claiming to need to post it in the OP. Voltages are based on Samsung's drivers and only a handful of people since October have reported such issues, if at all. If there is a true need for this then I will simply raise the voltages from the kernel's side and be done with it, but it seems to be a rare exception rather than a common rule. Remind yourself that Perseus and its variants has the single largest user-base around here, people would be reporting such problems more often.
[Galaxy Note II Original Android Development] KingpinZero:
i see, still thanks for your fix. Ok then, is fine as it is :) I was just suggesting to write 2 lines in the OP as ive encountered other users from other places (foreign forums) that had this issue. They link always to this thread, so a quick info about the problem could help. (i didint want to sound rude, or make a bold claim like forcing you to do something you dont feel appropriate, wasnt my intention at all).

Either way, its your decision, and i fully understand it. Thanks for helping me out, im enjoying your kernel as ever :D

Maybe your wireless charger give your note 2 unstable power.

If you want, you can try enabling "ignore margin" and "ignore unstable power" in stweaks maybe..

Guys, I have a question. I always remove cache and Dalvik cache before I flash a new version of Perseus. But I wanna know if im doing it right. You have to wipe cache and Dalvik cache before flashing a new perseus everytime right? Thanks in advance my fellow XDA brothers! :D

For what it's worth, I don't wipe anything when upgrading in the same kernel family. And never had a problem. Obviously, if something went wrong I would fall back to a wipe. So far so good!
[Galaxy Note II Original Android Development] Husy:
Thanks, I guess it doesn't really matter when it's the same kernel. Thanks for your help mate. I'll just flash it normal and if I get any problems I will just do the same as you and do a wipe.

Anybody knows how to make the LED blink like the one in BB phones ?? The stock one in note2 is slow and feels like crap.. I tried to change the values in stweaks but in vain.. Help :)

Up this question if you wish to have the same :)
[Galaxy Note II Original Android Development] Pyr0x64:
How do BB phones blink?

If you remove the tick from the fading option in STweaks and lower the fade-in and fade-out time periods you can speed up the LED blinking

2 Issues with update 35: Please help...

I noticed a very specific performance issue. When I typing in landscape mode in certain resource intensive applications, there is an extreme lag/delay in landscape typing (on all keyboard apps). This lag is very noticeable for fast typists like me. I can often type a whole word before the word displays on the screen. If select "Performance" governer, this problem goes away. I am not sure if there are any drawbacks to using "Performance" governer all the time; or if there is any way to fine tune settings specifically for this problem using perseus default governer. I would really appreciate any help with this.

Also, I noticed that certain programs that need direct access to the LED for customized LED actions/notifications, behave unpredictably. Is the new LED options compatible with 3rd party applications, such as email apps that customize LED color during notications? Is there a better way to customize LED email notifications so they have a custom LED color? For example, will Perseus LED customization break 3rd party LED color managers such as: Android Light Manager

Thanks in advance,

how much is led notification light battery hungry? i configured led to most brightest settings all the time(no mather if im in the dark room) i like it nice and blinky

i usually lose 5% overnight 8h, lets say if led notification blinked all that time how much would i lose additional %?

The value can never be given in % because the LED consumes the least power and it will not bring down the battery... You wont find an answer better than this :D

LED notification

Hi,

i'm very very happy that finaly perseus kernel has LED options like fading, that for me is much much nicer then the default blinking.

Unfortunately, with this last kernel, light flow, even with last version, 3.6.3, dont hand very well this new kernel. When i have for example more then one notification to be seen on LED, for exemple green for email and orange for calendar, it only shows the first one. With previous kernel everything works ok.
[Galaxy Note II Original Android Development] GonDr:
I have same problem in led manager and light flow and i guess its related with android logger.
[Galaxy Note II Original Android Development] ravenrocha:
Hi,

and if u disable android logger, it solves the problem?

There is no option to disable or enable android logger in STweak in this kernel. so i hope Andri will add it next release.
[Galaxy Note II Original Android Development] mkanet:
I am hoping someone who knows stweaks settings very well can help me....

I looked at CPU utilization more carefully (Using Perfmon 1.1) on my Samsung Note 2 with Pegususq governer preset on Perseus version 35. For some reason only 3 CPU core are utilized at all times; even when 3 CPUs reach 1600mhz with newly full utilization. The only time I've ever seen all four CPU cores be utilized is when playing one of my 3D games. After exiting the game, I am finally able to use all 4 cores in other CPU intensive tasks.

What Stweak setting allows the use of the 4th CPU core more often (when needed)?
[Galaxy Note II Original Android Development] jujuburi:
Flashed the latest version and the LED has stopped working completely, if you keep the LED Fade option checked, the default option! If you uncheck it, okay, but that's not the point I guess.

Oh, I'm on Omega latest.

PS: Nonsense, ignore it.

[Galaxy Note II Original Android Development] ROX77:
You have to reduce the runqueue depth from 3 core to online and from 4 core to offline, in the cpu hotplug section. Try to set these values to 300.
[Galaxy Note II Original Android Development] jujuburi:
Ah, damn it, shame on me! Actually I used to see the LED blinking almost instantly after hitting the 'test' option under Light Manager, on Stock or other kernels. This time I had to wait for some 2-3 seconds for the LED to appear, and I don't think I can change that, right? No big deal anyway.

One more thing I might ask, I'm seeing some comments that even on full load all the cores are not activated, is that true? Should I lock all the 4 cores under S Tweaks then?

I don't like slow stuffs, that's all ;)

Btw- Great work Andrei, gotta admit.

But again, with this new kernel, if u have more then one notification at same time, the LED stops to work and u cant see any. I'm using last version of light flow. Everythings works ok with perseus 34.2 but with 35, more then one notifcation at same time u have no lights :(((

Just to add, that if u disable LED fading in perseus 35, everything works ok with more then one notification at same time. Its realy a problem when u use the fading option.

Im not able to alter the led blink rate either. It doesnt matter what I set it to. Also, ever since the new LED settings, I am no longer able to use my Email notification client which has custom LED alerts. It just makes the app hang.

Sorry if I missed this earlier, but does anyone know how to alter Perseusq so that my forth CPU core get's utilized? I've only seen the forth CPU core utilized once since I started using Perseus; and, I definitely push my phone to use most of the 1600Mhz on 3 cores... but fourth one doesnt kick in.

[Galaxy Note II Original Android Development] sklchan:
The LED setting especially on the brightness setting seem it's not working depending on each and every colour led (my observation the Blue led is follow the setting but the green led not) then the pwm controller setting is not straight forward and you need to combine with proper on/off delay to get nicely fading effect... Anyway this kernel is by far the most advance kernel for note 2 and Andrei clearly shown he do know what he's implementing... :thumbup:

[Galaxy Note II Original Android Development] mkanet:
Edit: Actually, I tried using it a little bit more. It looks like it depends on what application I use. Some applications will limit them selfs to only use 2 cores (such as when using the keyboard); even if both cores are fully ultilized. I have to open another application that doesn't limit itself to only 2 cores... then, it looks like your CPU hotplug modifications are taken advantage of... and, do what they're supposed to.

Is there a setting that forces all 4 cores to stay on...

only staying at low frequency when not utilized. I think that would be a better way to do it for what I want.

Edit #2: Nevermind, I found the hotplug setting which disables all hotplug logic; setting value to 4 cores. I'll test it this way to see how much more battery it uses this way.
[Galaxy Note II Original Android Development] omniwolf:
don't forget that if an application only runs on one or two threads, forcing the CPU to keep 4 cores active will do nothing. It will still just max out the core it's running on. You can't run one thread on multiple cores. They keyboard is probably mostly single threaded, it technically cannot use more than one core, your phone will only be using the other cores for other threads happening in the background.
