[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
I've never seen so high temps, perhaps the first SoC was in a bad state or had a defect? Samsung repair says olny "new mainboard".

For now I have good news.

After 1h RR3 I have 96°C and in energy safe mode it goes down to 70°C. I think RR3 is now more fluid, between 8 and 10 frames more per second an a better image quality. The 733mhz step works and also the 933mhz speedstep lpddr3 works.

I compared AnTuTu and Quadrant results with old results and observe frequencies and temps with TricksterMod, Mali Status and Android Tuner. At last OpenGL test sequenz from antutu runs 10fps faster than with stock kernel.

I think, really a good work!:D:good:

I am watching this with curiosity....I changed the initramfs at my galaxy s years ago...have now the p605 as well...

[MENTION=5529656]xluco[/MENTION]

You have said changes in the initramfs are suficient (no kernel modifications) to get it to permissive mode, but fastguy could not reproduce it.

Could you please elaborate and also say what needs to be changed at init.rc?

[MENTION=283124]fastguy[/MENTION]

Did you change the kernel or ramdisk only?

Thanks in advance :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] fastguy:
Hi, in my findings changing initramfs did not help, disabling selinux rendered the tablet unbootable (might be due to stuff in userspace requiring the selinux), but just changing some enforcement status to N in the selinux defconfig, compile kernel and use it with same initramfs and let it boot and selinux can now be switched at runtime. (ie use selinux disabler from market).

I'm now using this kernel but it seems it's from earlier version and had the standby wakeup lag. I have compile new one with 4.4.2 firmware and sources.
[Galaxy Note 10.1 (2014 Edition) Original Android D] tincmulc:
I think having the thermal limit raised by default is a bad idea. You don't overclock by default and messing with thermal limits is more dangerous than overclocking. Just because the shut off point is 115 does not mean that anything below that is perfectly safe for hour long gaming sessions. In my opinion the thermal limits should be at the defaults or configurable (cool-normal-fast(hot) thermal profiles?).
[Galaxy Note 10.1 (2014 Edition) Original Android D] OMIGHTY1:
v1.2 first impressions

I installed v1.2 yesterday, and it's quite a bit better than v1.1. The GUI is faster to respond and animate, the animations are more fluid, and the overall system stability is better. Looking forward to the next regular release! Great job on this kernel!
[Galaxy Note 10.1 (2014 Edition) Original Android D] :
V 1.2 is great:thumbup:
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I think you're right. Reverted to stock in 1.3 :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
good idea! At about 80-90 ° I get a bit afraid at a long run, that something breaks again.:(
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
v1.3 added to the OP

http://d-h.st/VCN

Only changes are reverts to the thermal throttling and we're now at Linux 3.4.41.
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
You are so fast! Thanks!

First test:

Thermal limits works

Cpu slows down

Ram slows down(don't know 933mhz works)

Gpu something slows down(don't know 733mhz works)

Maybe the stock limits is a bit too low. we must find the optimal value only, for best performance at acceptable temps.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I've been playing around with the limits some more for 1.4. But for the time being you can change them yourself in /sys/module/EXYNOS_THERMAL

If you do change them let me know how you get on and ill add them to 1.4 :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Okay, I'll try. Compare the values ​​with 1.2 and will try to go slowly higher with the limits.

Something funny I noticed with 1.3 is that in energy safe mode I have bit better GPU performance and lower temps average of 75 °C. But this is the best game setting for me, because the temps are longlasting moderate.:good:
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Have the termal limits raised by 2-5 ° C, but can not find much difference in temperature evolution.

We have with us 30 ° C + outside. :D

Benchmarks are too scattered for reliable diagnosis and with MaliStatus in background RealRacing3 fc after a few minutes.:silly:

I think 1.2 settings are a little bit faster, but 1.3 is more secure! Noticeably differences are only in benchmarks, there are a few fps more. But in daily using I find no differences. So I tend to 1.3 + a slight increase for later throttling. Unfortunately works trickstermod not 100% and there is no tool for gpu settings. Has Halaszk nothing in the pipeline like XT-Tweaks?

Currently your kernel is nearly perfect, we only need a tool for him.
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Hi! I have a brand new little problem. I think the battery can not supply enough juice for the overclocked GPU.

I had 2 freezes during the game and after that an extreme battery loss.

After a waiting time of 5 minutes and a reboot, the battery has regenerated and the performance stand before the freeze. The loss was more than 20% and that all happened in the Energy Safe Mode. I think I play in future only with powercable pluged in or use the stock kernel till we have a tool to modify gpu frequences.

I don't have that Problem with V1.0stable, so I think 600MHz is okay for my battery, but 733Mhz uses too much juice.
[Galaxy Note 10.1 (2014 Edition) Original Android D] halaszk88:
What is your GPU voltage settings at 100 to 733 MHz steps?

I make some screenshot my N3 device before my screen was not broken. This is my voltage settings and it is not unstable and not eat extreme battery.
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Hi Halaszk,

Synape app don't works for me atm, says no UCI support. So I don't can read the voltage settings for now. Perhaps Xluco add Synapse UCI support in a newer kernel-version. For now we must ask him about the voltage settings in 1.3.

Or have you a trick to get Synapse working on Note 10.1, like rename in build.prop. or so?
[Galaxy Note 10.1 (2014 Edition) Original Android D] zhuhang1694:
Hope there will be a synapse for note 10.1 2014. It's more convenient to adjust the OC .
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
1.4 coming tomorrow with sound control from AndreiLux :) once thats out I'll focus on getting synapse working, then upstream to linux 3.4.92 then CPU OC and thats pretty much everything I originally wanted to do haha
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Yeah! Good to hear! But can you post the voltage settings from 100 to 733mhz or use we the same values as Halaszk? (Looking to the pictures from Halaszk last post)
[Galaxy Note 10.1 (2014 Edition) Original Android D] zhuhang1694:
Nice of you!! After the kernel came out I can really enjoy the tablet.Before that, the tablet was a joke.Everything was laggy.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
removed
[Galaxy Note 10.1 (2014 Edition) Original Android D] AndreiLux:
Are you the guy who asked me about it a few weeks ago? I see that your commit consisted of the modifications I posted in the comments of that discussion for porting it on the tablets.

Let me know if it actually works.

Edit, I see you fixed an issue regarding setting speaker volume registers from my diff post. So I assume it works well, good to hear.
[Galaxy Note 10.1 (2014 Edition) Original Android D] calebcabob:
180° TEST

Nope. I use that feature all the time too. I hope my testing helped you out buddy;)

Once these few bugs are worked out, we'll be in good hands!

[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Hello,

no, the tablet works as normal, the digitizer controls the pressure sensitivity. Turning the wacom pressure sensitivity off when the pen is inserted and just enabling normal touch control should save batter :) I'll reword the OP in a sec
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Hi, I'll look into it but I'm learning as I'm going along so don't expect anything too quickly :) I've also got a feeling that enabling ART may be more ROM based but I could be wrong.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Hey, I had the wireless issue too, theres instructions in the OP about changing build.prop that fix it :)

I'm going to re-enable logger for the time being in v0.2 plus just to work out a few niggles. If it happens again let me know but 0.2 has a couple of stability fixes which I'll upload tonight.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Hey :) ill look into it but rotation seems to be working fine on my device, though i dont have xposed installed. Are you using a custom rom.
[Galaxy Note 10.1 (2014 Edition) Original Android D] abdielol:
My rotation is working perfectly. I have been having random reboots though. Other than that, everything seems smooth.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
right guys, I'm overclocking to 2.4ghz, everything is booting but its far from stable. If anybody knows anything about voltage tables or anything to do with the file " arch/arm/mach-exynos/include/mach/asv-exynos5420.h " I'd be very greatful :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] steveman29:
I can't get my flash drive to work using OTG. with version 0.1. Does anybody else have this problem too?

EDIT: Flashed the rom again and now it is working fine with the kernel.
[Galaxy Note 10.1 (2014 Edition) Original Android D] OMIGHTY1:
How did you even get it to go above the stock 1.9Ghz? Even with this kernel, it won't go any higher. I normally use ROM Toolbox for overclocking.
[Galaxy Note 10.1 (2014 Edition) Original Android D] 22sl22:
Maybe because the person you quoted is the person who made the kernel and is privately testing a new version that includes that option. :good:
[Galaxy Note 10.1 (2014 Edition) Original Android D] suzook:
Any possibility of adding color/gamma controls? That would be awesome!
[Galaxy Note 10.1 (2014 Edition) Original Android D] OMIGHTY1:
Oh whoops

Here I am not noticing things again. XD

I had just woken up, so I was still kinda sleeping.:p
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I'll look into it, though I'm gonna say right off the bat that it's probably beyond my capability and tbh I really like the colour of the screen atm so it's not gonna be top priority :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] suzook:
Thanks, color really not an issue, but with gamma controls, we can get some better blacks on this thing. Its my only complaint.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
v0.2

v0.2 added to the OP

v0.2 is here. It brings OC to 2.1ghz, which is available but not enabled by default (switch to it with you kernel modding app of choice) for testing purposes. 2.4ghz was bootable but not for long, I'm working on that for .3.

The logger is also re-enabled in 0.2 to fixes a few niggles - logcats are greatfully recieved.

More complete changelog in the second post!
[Galaxy Note 10.1 (2014 Edition) Original Android D] Koserman:
BOOYAH! I ran out of thanks for today but tomorrow starts anew ;-P Will test shortly
[Galaxy Note 10.1 (2014 Edition) Original Android D] steveman29:
It is running fine but it is stable only at 2000 Mhz. It will freeze if i run stability test at 2100 Mhz. Are you planning gpu oc for the future too? Anyway thanks for all your efforts[emoji106]

Hey :) no that wasn't me but I did use the diff from that conversation. Unfortunately I couldn't get it to work, with or without the modification the sound is only coming out of the left speaker. I've tried playing around with it some more but I think it's way beyond my ability ;)
[Galaxy Note 10.1 (2014 Edition) Original Android D] AndreiLux:
We can try to debug it together in the weekend. I'll write you by then.
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Hey xluco, Tab S is out and uses GTS for all 8 cores simultaneously. There is universal5420 / revision r2p3 board installed, so the same SoC as ours. Maybe we'll find soon GTS for our Note 10.1?
[Galaxy Note 10.1 (2014 Edition) Original Android D] nrage23:
It has been announced but it comes out in July.
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Yes I know, that's why I ask maybe, haha!

Xluco does good work and I hope only there is a way to port the GTS stuff into this kernel later.

:good:
[Galaxy Note 10.1 (2014 Edition) Original Android D] Stevethegreat:
Does everyone else have the instability issues that I face with this kernel? I cant even run antutu without my tablet crashing. Reverting to stock of course fixes it all. Trying the later versions I found that they are kind of stabler but I still get the occasional crashes... it's a fast kernel but sadly unusable for me. Does everybody else faces that?
[Galaxy Note 10.1 (2014 Edition) Original Android D] vprasinos:
No crashes here but 1.2 and 1.3 overheat my GPU (the frame beside the screen gets too hot). However super smooth experience overall (far better than any other tweak).

In what apps do you get the crashes?
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Hey Vprasinos,

I also have only a few fc in browser or games, but no system crashes after V1.2 and1.3.

How hot is your SoC with 1.2 or 1.3? I can gamble only in energy-saving mode and have temps around 80°C.(realracing3)

But even with stock kernel it gets pretty hot! Stock limits are 95° for cpu and 75° for the gpu. The most hotheaded are the 4 A15 cores I think, because I see the most throttling there.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
1.4 added to OP

Lots of futex and security changes. The futex patches seem to have gotten rid of my screen-on delay so thats nice :)

http://d-h.st/FWX
[Galaxy Note 10.1 (2014 Edition) Original Android D] vprasinos:
I don't play many games so can't comment on gaming FCs. However all browsers work normally no FCs there (have notices 1-2 but those are the browsers themselves to blame because they were there before the xluco kernels).

Trying to use temp in status bar xposed module but don't know what file to measure. They also show 3 trailing zeros and I end up with a temp like 75000C :cyclops: Which app do you use for temp measuring cpu and gpu separately?
[Galaxy Note 10.1 (2014 Edition) Original Android D] Stevethegreat:
In benchmarks and mostly when I have more than two apps open at the same time (multiwindows). In short whenever my system is (being) pushed, sometimes trying to play flash content did the same, etc...
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
I think the browser fc are chrome related and RR3 crashes also with stock kernel, so it is the game.

To have a look at your temps, you can use Cool Tool, AndroidTuner or TricksterMod from Play Store for cpu temps and an app called MaliStatus 1.0 here from this thread for live monitoring gpu values like in Cool Tool app.

[MENTION=5529656]xluco[/MENTION]

Thanks for v1.4
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Hhmm! No problems here. 4 way multiwindow and antutu works without fc with V1.4. Flash not testet jet, other things are not kernel relatet. which rom do you use? I have many more issues with xKat V3.1 than with UXproject V3.0.
[Galaxy Note 10.1 (2014 Edition) Original Android D] justme_135:
Hi. I have a question. Which application am I supposed to use to control this kernel? I am using trickster mod but I don't have the gpu oc option. Thanks

---------- Post added at 08:31 PM ---------- Previous post was at 08:23 PM ----------

No, not at the moment. Xluco will add support for Synapse app as soon as possible. But for now there is no way to configure out the kernel. Only with scripts is it possible to manipulate GPU setting.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I'll add synapse support next release but if youre desperate, I posted a small script a few pages back :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Hi xluco,

I have still the same problem with the power consumption in V1.4. If I play a while, breaks in the battery and the tab reports "connect to the charger". If I then give him a minute and shut down for a while then he regenerated again to the value in front of the power loss.

The error is reproducible and occurs also in 3DMark or on other graphics-intensive applications. Even when enabled, Energy Safe Mode. So I think it's the GPU that draws so much energy. Halaszk has post 2 pics a few sites back with his voltage settings, use we the same. I don't have that problem with stock kernel. Hhmmm!
[Galaxy Note 10.1 (2014 Edition) Original Android D] SamsungGalaxySamsung:
Nice work
[Galaxy Note 10.1 (2014 Edition) Original Android D] vprasinos:
1.4 still overheats my GPU. The bezel under the samsung logo gets too hot when using a browser or a GPU intensive app.

I'm working on it :) 1.5 tomorrow night (GMT)
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:

1.5 added to the OP

Some build fixes from C0ryB4k3r, and GPU voltage tweaks from the other page.

http://d-h.st/Czj

I was going to add synapse support to this one but I can't get my head around it, so sit tight for now, I'm working on it
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
Thanks! I will test it tonight!
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
I've tested v1.5 and seems that all is working so far. Temps are a little bit lower, but no fc's or freezes. Seems that you can not get the hothead 5420 better in the handle.

Say, have you improved battery charging times? Seems it goes a little bit faster!
[Galaxy Note 10.1 (2014 Edition) Original Android D] tincmulc:
Did you reduce GPU voltages? I get a freeze a few seconds after booting.

Let users undervolt on their own. I said this before: all voltage and frequency setting defaults should be at samsung defaults, all devices are different when it comes to UV/OC and you can not safely provide any OC or UV in kernel's default settings.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I don't UV people complain, I UV people complain, I don't even play games on my note so tbh its not a priority for me, that being said ive reverted it and ill push a new version soon
[Galaxy Note 10.1 (2014 Edition) Original Android D] tincmulc:
Don't worry about this too much, after you implement synapse(or something similar), the gamers will be able to cook their gpus all they want(although they could do this now, via scripts), while you get to keep safe defaults. If anything goes wrong it'll be their own tinkering that caused it.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
1.6 is up

Lots of changes, too sunny to list them all, checkout the new 'staging' branch on github

http://d-h.st/9d8

The GPU voltages are back to normal with a couple of minor fixes which relate to fixing a few voltage references (one file was pointing to incorrect numbers in another :/)

Enjoy
[Galaxy Note 10.1 (2014 Edition) Original Android D] ollimi1:
V1.6 runs good, everything works and temps are only 3°C more than with V1.5. Seems to be not much will change!

I want to test tomorrow whether there is battery dips . But so far looks good. Since V1.5 no battery break-ins!

Is there a way to change the resolution at fullHD, without having trouble with some apps, to relieve the gpu and to improve the fps-performance?

wow, looks interesting, I'll test it out later :)

I'll give it a whirl later once I've managed to get 1.7 out, though I'll need a stock ramdisk from the p-601 as well

I think its got to do with the CFLAGS used in 1.6 causing a chain reaction of broken, hopefully that'll be fixed by tonight :)
