HAHA, I requested temp monitoring. I am glad he is putting it in thats awesome.
[Asus  Eee Pad Transformer Prime] boynamedstacy:
The dev owes you guys a thank you. I just bought :-) Seems pretty sweet. The temp thing will be nice since she gets so warm now at 1.8. Thanks for the heads up guys
[Asus  Eee Pad Transformer Prime] di11igaf:
Hey guys a lot of programs report battery temp, not actual CPU temp. For our device if you want to see the actual CPU temp at any given time, (with root-explorer or how ever you'd like) just check /sys/devices/platform/tegra-tsensor/tsensor-temperature

Has anyone succesfully overclocked to 1.8 on virtuous .21 v1?
[Asus  Eee Pad Transformer Prime] PapaSmurf6768:
Haha yeah I've had that app since it first came on the market but I'm not smart enough to use it :) I just assumed set CPU would work.

Doesn't overclock past 1.8 for me on my virtuous rom, gonna try it on the stock stock rom.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
well it can't go past 1.8 since the kernel only supports 1.8

Yeah I know, I was also following that thread ;)

Come on demandrin take the plunge and unlock your bootloader, I was on the fence about doing it and I finally unlocked my bootloader 2 days ago and I do not regret it one bit. ;):p
[Asus  Eee Pad Transformer Prime] :
Kernel removed

will provide flashable zips in future

pls be patient and expect an updated kernel tonight :)
[Asus  Eee Pad Transformer Prime] :
Forgot to mention removed previous changes that prevented overclocking ofcourse :)

An update coming tonight with more changes :)

Edit: @tyler i just recieved your mail, thanks for testing, so the kernel @5th april was good? The kernel above is much more improved, plus i think i can spend an hour tonight n make atleast 10+ great changes :D
[Asus  Eee Pad Transformer Prime] notoriouspk:
Sounds good looking forward to it .zip flashable plz
[Asus  Eee Pad Transformer Prime] :
I can go from ramdisk to blob without parameter error, meaning ill create flashable zips from now on, just didnt have enough time in the morning, @ work now so cant make it :/
[Asus  Eee Pad Transformer Prime] newellj79:
Would love to try a version of this with aokp... :)
[Asus  Eee Pad Transformer Prime] CekMTL:
Maaan this sounds like exciting and great news!!... by the sounds of it, and all the changes I read, this Tegra3 seems to have a lot of "goodies" :))))

As always thank youuuuuu!!!!

Edited as per shakys request

if im not mistaken i think the 2d/3d gpu clocks were at 520, just curious what you set them at?
[Asus  Eee Pad Transformer Prime] :
Theres alot more to come, and motleys on it too, so i think motley next version will contains atleast total of 30+ in changlog, thats my target

Gpu clocks set @ 600mhz :)
[Asus  Eee Pad Transformer Prime] brantje:
Would it be possible to overclock to 2Ghz?
[Asus  Eee Pad Transformer Prime] demandarin:
I'm sure in due time. These things aren't that simple and need to be tested for stability and such. I have no doubt we will reach it. its about finding the best way to reach it and stay stable At the same time.

IMO, I think gains in gpu overclocking will have a bigger impact. especially after CPU is overclocked.
[Asus  Eee Pad Transformer Prime] benefit14snake:
Hey Shaky, do we know which bus is responsible for communication of the CPU/GPU to memory? I would imagnine (not too up to date on my SOC arch) it has an IMC right? Just wondering if memory bandwidth has been increased. That could have some significant effects on our 3d performance. Nvidia says tegra3 is not starved for bandwidth but I wonder.....
[Asus  Eee Pad Transformer Prime] :
Ill check it out

I looked @ the code before, i agree nvideas emc isnt limiting the gpu :)

Edit: @di11igaf can you pls edit your post and remove the quote to kernel, its not a flashable zip ill create one tonight
[Asus  Eee Pad Transformer Prime] notoriouspk:

Just wanted to know isn't wifi eating a lot of battery when idle ?

2.5 alpha version trial 3

2.5 alpha version trial 3 - this includes the first round of changes that I am working on with Shaky156 as well as as some other stuff I added. I'll get the commits posted into github soon so everyone can see what else has changed and so we can work from the same base going forward.

This is not fully tested and is an early alpha! Only specified testers or interested developers should flash this. If you haven't officially talked to us about testing, please do not ask general questions about this build in this thread. We will only entertain technical/dev related questions and reports from the testers until the official release of 2.5

Update: official v2.5 released (link to alpha removed)

Notes/comments:

GPU OC is working @600MHz (up from 520) - AnTuTu shows 65fps+ on the 3D tests. My 2D scores are also higher than before as well. Shaky, your changes in this area were the same the ones I was working as well from the Nvidia git. I also had added a few more changes from the Nvidia commit I referenced (tegra3_dvfs.c) that I think were necessary to get it to work. Had to freelance a bit, so I am looking forward to a review by another pair of eyes.

I also have some questions about a couple other things. One thing is that I am holding a commit because I want to understand your change a bit better (arch/arm/mach-tegra/headsmp.S). What is commenting out the .size doing? Is there a commit somewhere I can reference? The change is in this build, but I want to understand more about it before I commit.

I left the 2.0 OC out as there was more stuff that needed to be changed for that to work. Max clock speeds etc. We can try that or a 1.9 next should we be successful with this set of changes.

I don't want to change too many things at once with each test cycle so we can track issues should they arise. After this round of testing, we can see where we are at and then we can review what is slated for the next round of tweaks.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
testing this beast out now

---------- Post added at 04:20 PM ---------- Previous post was at 04:11 PM ----------

Running AnTuTu got a score of 13241 on 1.6GHz and my 2D score was 319 with a 3D score of 3571
[Asus  Eee Pad Transformer Prime] boynamedstacy:
Tyler, you still on Jermaine's V1.0 with this new test kernel? What speed were you running at for the AnTuTu?
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
no i'm on stock this won't work with AOKP and that was at 1.6
[Asus  Eee Pad Transformer Prime] boynamedstacy:
I was thinking that. Thanks man
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
yeah it's not worth reversing for this kernel yet, let me do more test first
[Asus  Eee Pad Transformer Prime] benefit14snake:
Running great on performance mode. Balanced seems to have some really noticeable lag within the UI. Even simple stuff like swiping from one screen to another lags. Ill see if bumping up the voltage on balanced helps.

EDIT: Took CPU2 from 1200 to 1300 and now it is smooth as butter!
[Asus  Eee Pad Transformer Prime] CekMTL:
Everything seems to be working great at 1.8GHz; feels snappy and video ok (tested with glowball demo for 5 minutes).

Thank you again.

Tested with hulu streaming with 480p flash, all nice and smooth, and browser scrolling was also smoother.

Tested with 1080p mkv movie and some trailers, and all good also.

I will leave benchmarking to others, as i am no more into that, just want tf to be as snappy and seamless as possible for my normal daily usage :)

If i put balanced or eco mode (1.3 1.0) the video refresh while swiping between home screens is kinda slow and not fluid as before (with or without 2D acceleration)... its like watching a 29fps movie with only 15fps...

Since motleys released a kernel i wont be releasing one tonight lol, but great to see feedback, and awsome work motley! :D
[Asus  Eee Pad Transformer Prime] di11igaf:
lol, i just spent literally 2 days trying to isolate a bug where anytime i put my prime to sleep with my kernel, when it unlocked it would be stuck at 620mhz on only one core, only way to bring the other cores up was to manually do it in /sys/devices/system/cpu........ i tried EVERYTHING to fix this, thinking it was a either some kind of hotplug/smp bug in my kernel or edp keeping it in a LP state(even turned all thermal throttling and edp off, bug still there). decided to scrap all the overclocking i did just deleted the whole branch after compiling probably 200 times. then i cherry pick motleys OCing commits, same issue.

turns out this whole time it was a ramdisk problem, i was still using an older one from about .15 or so. soon as i updated all the init files in ramdisk, problem gone.

my tablet may not live through the night.

/rant- lesson of the day- troubleshoot simple things first, even if you think it cant be the problem.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
Sounds like a tough time, hopefully all is well now!
[Asus  Eee Pad Transformer Prime] _motley:
I think it is just a voltage issue. I bumped balanced and battery saver mode (cpu1.sh and cpu2.sh) to 1250mV and it is smooth. This makes sense sense as the clk speed was upped for gpu, emmc and some others devices.. I have some ideas, but they will have to wait til tomorrow. For now, if you use the alpha v2.5 from the post above, just add 50mV for the lower 2 modes.
[Asus  Eee Pad Transformer Prime] CekMTL:
_motley, I can confirm that bumping +50mv (1250mv) did the trick and all is smooth now in the land of balanced and battery saver mode, thank you again!

Is there any way the auto-contrast could be disabled in the kernel? Appearantly the tegra feature is either called

" NVIDIA PRISM Display Technology - PRISM (or Pixel Rendering Intensity and Saturation Management) reduces a mobile device’s backlight power while simultaneously enhancing the pixel color to deliver the same visual quality with substantially extended battery life."

Or "Tegra 3 DIDIM tecnology" http://www.tegra3.org/tegra-3-didim-saves-even-more-power/

Here is a thread discussing it for further explanation :

http://xdaforums.com/showthread.php?t=1542367
[Asus  Eee Pad Transformer Prime] _motley:
Thanks for the info about this. My preference would be to fix it and not remove it, i.e. slower the transition rate. There is some code in the kernel that I can try to tweak.
[Asus  Eee Pad Transformer Prime] :
Looked like a great feature from nvidea till i clicked on the thread, is it that bad?
[Asus  Eee Pad Transformer Prime] CekMTL:
Well I watched some series and movies, and I would say it's noticeable but it depends on what you are watching... also depends on the backlight % you are using, and if it is in a dark room and so...

Once I remember it did get to the point of being annoying, so maybe add an option to have it disabled in performance mode via /sys/... key or something similar to put in cpu3.sh ...?

Enviado desde mi Transformer Prime TF201 usando Tapatalk
[Asus  Eee Pad Transformer Prime] Kupfel:
It is just annoying. Certainly not a reason to sell there prime like the one guy in the thread did :D I mostly notice it when watching anime. The picture keeps changing from bright and vibrant to darker and dull. It keeps doing that like every 30 seconds or something without any reason to do so, so you really really notice when watching anime for example since they are very colorful with big areas of the same color etc. I suppose it might be a good feature if you needed a really long battery life and this makes the battery last 30 minutes longer so it could be active in power saving mode or even balanced mode. I see no reason for it to be active in power mode or when the power cord is plugged in :)

I like my screen bright so I always have super ips+ mode enabled. It is probably most obvious when your your screen is set to pretty dark or very bright.
[Asus  Eee Pad Transformer Prime] jingquan:
Opps, I meant 1.7ghz tops on the virtuous rom. Although I.8ghz works on the stockstock rom, my tegra can't handle the heat during antutu's benchmarkings and began to disable its cores. Without an icepack behind my prime during intensive processings it will start to show symptons of heat fatigue. :)

I guess hitting 2ghz is a matter of cooling now. :eek:

Oh and im excited to try out the gpu oc when I h%ve some time.
[Asus  Eee Pad Transformer Prime] CekMTL:
Yeah, I see what you mean, in my case I haven't watched any kind of Anime, so haven't really noticed, but I also agree that in power mode, it should be an option to disable it...

Thanks! Kind of sucks since im 24 and I need to get a micro discectomy (sp?) but it could be worse I spose.

Motley, I just had my first lock up. I was on balanced mode (1300MV) and had no load. I believe it was actually using the companion core since it was at 300mhz. I went to start tapatalk and froze. Pushing volume down and power got me where I needed to go.
[Asus  Eee Pad Transformer Prime] CekMTL:
Well... these words do sound scary to me, and I'm 36 so... anyways, I'm sure you will be in good hands!

About your lock up... something weird happened to me, but it was video related, was running on performance, and all of a sudden the left edge of the screen went all garbled, and the bottom part of the screen, before the status bar got all shaky and jerky ... it went on for like 15 seconds, and when I was about to reboot it, it just fixed itself... weird... (I swear there were no mushrooms involved hehehe).

[Asus  Eee Pad Transformer Prime] benefit14snake:
I believe it has to do with voltages.

I am not sure how voltages are connected (gated?) on this SOC.

I know the artifacts you speak of and mine were fixed with increased voltage on CPU2 (for balanced)

See the op for increasing voltage. I am not sure if it is required but for good measures I reccommend a reboot.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
I don't have any problems i already fixed all my voltages mine are set to 1250

Yeah mine are also set to 1250... that was the only time i had that glitch... i call it glitch coz after that, i havent rebooted my tf...and have continued to use it til now without any problems.

[Asus  Eee Pad Transformer Prime] di11igaf:
Motley, have you been thinking of trying bfs at all? Just wondering its something I've been wanting to try, got the patch to apply cleanly then got it to compile, won't boot though . Actually it boot loops

Tegra 3 just may not like bfs for whatever reason, I'm gonna keep tweaking though see if I can get it
[Asus  Eee Pad Transformer Prime] _motley:
I agree. I haven't seen it in perf mode, but I need to do more testing with movies etc.

Since you were on perf mode when these artifacts were observed, the 1250 wouldn't come into play for the lower modes. Make sure you have 1400mV in cpu3.sh instead of 1300 or 1350 perhaps?

I haven't tried this. Are you using the official Kolivas patch for 2.6.39? Seems like it should work. I have always stuck with cfs and autogroup, but it's always fun to try something new to see how it works. I need the BFS for my own life sometimes....to many things going on and not enough attention is paid to the task at hand LOL.
[Asus  Eee Pad Transformer Prime] di11igaf:
You ain't kiddin on that one. Lol

Ya I tried a few including official 2.6.39 from CK's site.

With us having a quad core I'm thinking bfs could benefit us more than older hardware, plenty of power left for background tasks with most CPU time for the task at hand. Sounds good in theory anyway

I did leave cgroups on, (sched_autogroup=n though) I don't think it should matter but I'll try it with cgroups off later.

Using ViperControl-mod.001 along with motley's 2.4 to OC to 1.8ghz

I originally flashed 2.4 and followed the instructions changing the scripts and cpu5.sh to cpu3.sh and I made the .bak file doing everything to the T using RootExplorer. I couldn't

achieve anything over 1.3ghz so I had this thought that maybe if I used ViperControl then I might get the cpu OC'd to 1.8ghz. I reflashed Vipercontrol.exe using windows explorer and then Waa-laa I ran the script in terminal emulator and this what I found: Quick Change modes are 1. power-saver 2. balanced 3. Normal (Performance Mode) 4. 1.5 (1.6ghz actually with motley's) 5. 1.6 (1.7ghz motley's). So there you go run VC in TE and pick option 3 for 1.8ghz. I hope this helps and I haven't tried it yet without making the script changes to see if it'll work without making those changes. So give it a shot and remember when you reboot you have to re-run VC in TE.

v2.5 released

v2.5 just released! See the first post for release notes and my git for all details.

Many have asked and I have now made it easier to install and set your performance modes. You have the choice to flash a zip in CWM to set your preferred performance modes:D

Note: for users that installed the alpha 2.5 that had the first GPU OC for the TFP, you no longer have to increase the core voltage for the lower performance modes. I am going to go back and delete the alpha zip in that post. Please use the official v2.5 now.

Let me know how it goes.

Installed Kernel and go into bootloop.

Had to flash stock kernel back in order to boot again. :(

Mabey voltages to low in kernel 4 my prime to boot up properly?
[Asus  Eee Pad Transformer Prime] CekMTL:
Sadly for me its a no go... virtuous 21 no scripts, cache + dalvik wiped.

When i boot, the first eeepad logo starts ok, then gets garbled for a split second then gets ok again and initiates the normal boot.

Virtuos logo comes in, fills completely and starts pulsating, then it boot loops (not enough gpu voltage?)...

This is the first problem i have with a kernel.

Back for now to s&b @ 1.8 without any noticeable problems.

Thank you for your time, if i can help debug just let me know.

I just did exactly what you said. I downloaded file into same folder you examples. I took off the .zip. then copy n pasted exact commands you posted. then I edited the path. then enter. it said files transferred. so i shut down n powered up. went to Asus boot screen. it acted like it wanted to update, with progress bar, but hung at beginning. then I saw white letters up top say blob verification signature failed. then device rebooted. I checked CPU spy just in case and nothing changed.

I do have Dr.Wowee EzOcerclock installed but I doubt that would cause blob verification signature to fail.
[Asus  Eee Pad Transformer Prime] jermaine151:
Thanks for testing it! It sounds like the signature isn't matching the signature they're expecting so it won't flash it. That sucks! :(
