GPU overclock enabled kernel - Touch Pro2, Tilt 2 Android General

http://forum.xda-developers.com/showthread.php?t=999679
this is for X1, but from what i read, they should share the same CPU/GPU as the Rhoduims
can this be incoporated into Rhod?

I spoke with some devs about this already, seems like it might be dangerous for RHOD.
ACL at least said he doesn't think it'll be useful for RHOD - we already have turbo mode enabled on the kernel.
Also, if you look at FPS scores we're right about where they're at - considering their resolution and they only get 3-4fps better on neocore? Seems about right, again taking into account the pixel res.

From the Qualcomm ChromeOS kernel: Adaptive Voltage Scaling?

So I was just looking around the Qualcomm open source (CodeAurora) repositories and noticed that lots of interesting things are going on over there for the qsd8x50 that aren't yet in our N1 kernels.
One of the most potentially useful things to us, is adaptive undervolting, that always chooses the optimal voltage level based on the current temperature and silicon process variations.
https www codeaurora.org/gitweb/quic/chrome/?p=kernel.git;a=commit;h=621d0e14e6fcf454974634cf822f06fba1bd6816
If someone could get this into an N1 kernel, we wouldn't need any more experimentation with undervolting and could always run at the maximum possible stable voltage.
Other interesting changes include USB host support (although it's unlikely the N1 hardware is physically wired to allow for this):
https www codeaurora.org/gitweb/quic/chrome/?p=kernel.git;a=commit;h=109894cac8d01c6273cfa0466f7823a04e919bea
Unfortunately, the Chromium kernel for MSM/QSD seems to be structured quite differently and being worked on by a different team to the Android kernel. Still, it'd be nice to see someone attempt to port at least the AVS patch to a CM kernel.
p.s. can a moderator please approve my account to directly include links? This manual link-munging is getting annoying
This sounds interesting
I know a lot of the devs here check out Qualcomm's latests postings, so hopefully they are aware of this...
Also of interest is their framebuffer driver. We need it in the N1 kernel to use their X11 driver.
Has anyone had any luck getting a CAF kernel booting on the N1?

Yeah I know, but this is their Chromium/ChromeOS kernel, not their Android kernel. Might have gone unnoticed (I for one, had not thought to look there -- I'd have thought the only Chrome-specific kernel changes would've been the X11 driver -- why should platform-power-management changes not be shared across both kernels?)
I ported AVS code to the N1 kernel.
You can download the experimental version here:
http://forum.xda-developers.com/showthread.php?t=654416
AVS kernel is very experimental, and I expect it not to be fully stable.
Also, it looks 1.275v is not really enough for 1.1 GHz - at least AVS complains that it cannot find stable voltage.

Funny that: a processor rated for 1 GHz (in a world where if they could get away with selling it as a 1.1 GHz processor they certainly would have) isn't actually capable of 1.1 GHz without compromising stability and/or lifetime. Who'd have thought
Cheers for porting it to your kernel though, I'll be interested to see if it makes much difference to battery life.
I got no problems with AVS so far - I will release new kernel update tonight with AVS with no overclocking, as AVS and overclocking do not mix well for some people. Also, I provided the patch-code on my github, so other kernel developers can use AVS too, if they wish. There is still an ugly hack inside (one liner, though) which I will fix tonight, too.
Regarding "getting away" with faster CPU (Qualcomm) - I am not really sure if they would do it. There are market pressures, and CPUs are not always binned according to test validation - rather, other factors are at play, such as market demand.
So, it does happen - if someone is lucky, that is - to receive a CPU which could be binned higher, but it was still released at lower frequency because of market demands.
Intel is a very good example of such practice, and I am sure Qualcomm is no different as this is a huge market.

No doubt about it. Look at the Desire for example. It will be equipped with the 1ghz Snapdragon but will be underclocked to 768mhz to preserve battery life. So while it is certified for higher speeds HTC feels the market would prefer longer battery life over a little bump up in cpu speed

Well, I've been using it for longer than .33 since I found it to be more responsive and a lot more stable with my 3d live wallpapers. Its also smaller when compiled so I can enable the compiler optimizations with ease.

Also, the upstream (AOSP) MSM kernel tree is still at .32... I would guess they may be stabilizing for a release as they've merged the -stable patchseries too (2.6.32.9 etc).

Overclocking

Just wondering if anyone has done this with success. I have heard of speeds as high as 2GHz and was skeptical of this being safe. I figured it would cause some overheating issues. Also what is the best app for this? If this is done is there any noticeable differences in performance(most likely as this doubles the CPU power)? How much battery life lost? Is it worth it?
Thanks
Seriously, use the search or take a peek in the dev section. 1.6 GHz is no problem at the moment. Oh, and for me, it is worth it.
Check out vipercontrol mod in dev. Section. Allows overclock to either 1.5 or 1.6ghz. PRIME CAN EASILY HANDLE this as it was tested by Asus themselves on those speeds. It was seen in the source at first but we couldn't use it. NOW Viperboy made it possible to use those higher speeds. Its more of a mild to normal overclock. Its very easy to do. You will need to install vipercontrol mod to your prime and also terminal emulator. INSTRUCTIONS are in that thread.
WE have even found another method to run parallel to vipercontrol mod to allow overclocking of all 4 cores to 1.6Ghz. Vipercontrol, St the moment, doesn't do that by itself. JUST ALLOWS normal overclocking as Asus had it.
Seems kind of odd that ASUS backed off on the performance by 30% don't you think? Maybe they just wanted to do more testing, or maybe it was a last minute change based on their first prototypes.
Mine seems OK at 1.6, but I don't feel the need to overclock it in general use - unlike my phone which I think will have a shorter life as a device anyway.

I think it was more about more money down the road. AS I'm sure you've heard of Lenovo tablet coming out months down the road. Its gonna use exact same tegra3 chip except with the 1.6ghz enabled on it.
THINK of it this way, why would Asus/Nvidia release its first quad core device already at 1.6ghz? Its already the most powerful tablet at its current state. They did this so down the line when newer tablets come out, it'll be more incentive to like the device or think it's more powerful if its clocked higher. If prime came out with 1.6ghz enabled already, then how would that look to consumers who buy tablets months later that have exact same speeds. PRIME would be the better value and those newer tablets wouldn't be all that appealing, As far as power goes. SO the newer manufacturers can have something to boast about. Like hey look at our device its clocked higher therefore more powerful. Another reason also they didn't enable it on the Prime was for battery life. At its current state, stock, prime gets excellent battery life no matter what mode you in really. HAVING 1.6ghz enabled, as I do now, drains the battery at least at the same rate as performance mode or more. PLusbif you add the extra boost to vipercontrol overclock using system tuner, then battery really drains alot faster. Because then I have all 4 cores running Max 1.6ghz at the same time. Viper control doesn't go that extreme, yet.
YOU ALSO have to remember Asus and Nvidia designed the Prime together. SO prime n tegra3 speeds are really a testing ground for future setups in future tablets. That's how we were already able to see the higher speeds a couple updates back but couldn't use them till vioerboy made it possible or you figured out how to do it with root and going into /system/etc and executing the cpu5.sh script.
I LOVE the overclock but find myself now going to stock speeds to see how they compare. STOCK speeds are really good, especially with ICS. EVERYthing is smooth n superfast.. Overclocking does make it even faster but the tradeoff is slightly faster battery drain. PLUS there's nothing out now that stock prime really can't handle. SO no real use for needing to overclock, yet. UNLESS you just want your device to be the fastest it can be. I keep switching now. Lol. Ill have it on stock speeds n as soon as I see a mention of overclock. It compels me to do it. N vs. Versa. ACTUALLY. Even with vioerboy overclock, battery life is still good. Just not as good as it would be on stock configuration. Now once bootloader unlocked, we will see overclocking paired with undervolting. So we can get Max speed and Max battery life. Or at least get the overclock to get same battery life or better as stock configuration. DONT be surprised if you see us hitting 2Ghz overclock soon. Its coming. Then if paired with system tuner, we could have all 4 cores running @ 2Ghz a piece all at the same time. unbelievable!

OK so basically today I've been thinking and I've come to the conclusion that I will release the 2D-core OC patch As Soon As Possible, 3D-core Core OC is NOT Impossible but for now I'll give it a break, I will attempt 3D-core OC If/When I can get a hold of a msm7x30/msm8x55 device, as it will make it much easier for both me & users.
So for now you can enjoy the 50mhz increase/bump up, perf boost 25% in 2D-core (will increase performance in both 2D/3D intensive appications as 2D-core is used for 3D AFAIK and increase User Interface performance (Note: This will not take a hit on battery life)), I will also release a couple of fixes on patchas kernel that shouldnt be there/set etc.
(Theres a device available in my area for roughly £90, if anyone wants to contribute towards getting that device or can donate a device , more than welcome and shoot me a PM so I can list you here.)
(This isnt a promise of 3D-Overclock if you donate, if you donate please do so expecting nothing I will only attempt 3D-overclock)

Hi, thanks, as I said, it takes more than editing the kernel graphics software layer platform data , that was not overclocking lol!
Wow, great work dev! This is incredibly awesome, especially for us Jellybean users who could use every bump in performance possible. After a lot of hard work, I finally have my 4.1.2 r800x on Paranoid Android at in AnTuTu. I can't wait to see what increases I yield with the 2D overclock and ESPECIALLY the 3D overclock. Please, oh please, try and get 3D overclocking implemented successfully. You will be a god-send to many of us Xperia Play users. While an old device, its purpose built and many of us still use it daily as a phone if not simply for an advanced gaming device. Expect a donation your way soon. I'm not sure if this falls on you or kernel developers but please make sure CDMA users aren't left outside the gate. We miss far too much in what's already a small development scene and I'm afraid this is something we simply cant afford to miss. Thanks again for your hard work. Keep it up!
On a side note, Turbo Kernel is no longer in development. Would you or anyone else be willing to patch these changes and compile the source for us still using the kernel? It's the best kernel I tested that works irregardless of phone or software version.

It falls on kernel developers as I have released the source, GPU OC isn't GSM specific so CDMA users sure will get it .
I usually release kernel before source code but due to my slow PC & Laptop, and I only have net access on the slow laptop I released source code first, cause kernel compiling for me is time consuming, when I do get more time, I sure will pull and compile that kernel for you

Can there be a ROM for gaming?

I would really love to see a ROM specially made for gaming in our Beautiful and powerful Xperia tablet Z (Pollux/Windy).
Can any developer(s) build a custom ROM with some performance tweaks just like as in EvoMix Kernel and extra gaming features like:
Resolution Changer (To increase the performance in games)
Google Play games integration
Ramp up CPU to 1712000 MHz
Ramp up GPU to 487 MHz
In-built support for Game Controllers
Game theme and boot Animation
Default I/O schedulers best for gaming {Maybe ZEN I guess as suggested in this awesome article about I/O schedulers http://androidmodguide.blogspot.in/p/io-schedulers.html}
GFX optimization (As in Gltools)
And other optimizations For Stability and performance.
Seems like a dream now and i know there will be a lot of work behind it. But Our tablet is built for performance and it can do much better with some performance optimizations. So Anyone interested?

Let's be frank, TabZ is 2.5 years old hardware, so while it can actually handle some games pretty well, the new ones are too tough for its GPU especially.
With some kernel modifications and overclock you can squeeze some more out of it, but Antutu ~26.5 is probably a maximum for S4 Pro chipset and Adreno 320 graphics (without heavy hardware voltage mods and cryonic cooling).
By using apps like GLTools, you can fine tune performance, but usually by degrading quality (lowering render resolution), and offloading GPU this way..
So can the gaming ROM be made? Sure, it can, but the use of it on old hardware (also software, cause Sony will not update it to Android 6.0) is under a question.
Devices built on Snapdragon 800 (801 & 805) like Z2/Z3TC are more capable of high quality hires gaming, while they getting older too.
Thanks @Rootk1t We can optimize a game in different ways.. And we can make heavy games like modern Combat 5 run smoothly on our Tablet Z. If you use a resolution changer app and decrease the resolution on your screen you can get a noticeable increase in performance in the game. With this if we have EvoMix kernel features like overclocked CPU and GPU etc.. I'm sure we can get rid of lags and play most of the games smoothly. But unfortunately, the resolution changer app does not seem to work with CM based ROMs.
I'm pretty much of a noob to developer thingy, but our developers know how to optimize the tab for max performance by taking out unwanted apps and adding some tweaks to the kernel/ROM.
I just can't wait for a gaming rom to be released.
But that's a sad news about Marshmallow

It's like gaming on PC. If don't have powerfull graphicscard or you have a laptop with built in one, you need to decrease resolution, let's say from 1920x1080 to 1280x720, after this framerate will increase, maybe to playable state, but quality will drop.
So the more you decreasing resolution the more drop quality of picture. On PC, we can add some antialising, on TabZ we're unable to do that, cause it's just won't handle that. On some games it is not very noticeable, on others it is very noticeable.
EvoMix kernel definitely allows some overclocking, but if you have CM12.1 you can test yourself, in Antutu or Quadrant, the gain from overclocking is not high, but at the same way greatly affects battery life.
Definitely depends on game, but is stressing hardware and battery.

It seems that CM is using another way to change resolution. Don't know is it a bug or a feature, but still there are mentions of it.
Try using other apps like Resolution Changer Pro.

Of course i had to test a few things myself (still a rooted note 3 owner). I tried my old "Nemesis", Retroarch, with a couple of games (3rd gen Cave shmups) that put to shame every smartphone Cpu sp far.
The games finally ran full speed, except for moments where a ton of stuff happends on screen and the framerate and audio start going a bit crazy. What is strange though, is the fact that the Cpu never goes beyond 1.7 ghz, never once, which is the little cores max frequency. I'd expect it to reach 2.7 which is the max for the big powerfull ones, to further smoothen the performance.
Is there something i'm missing here? There is no power saving activated and the game center(?forgot the actual.name) settings are set to performance (though from what i understand it only affects display, not Cpu).
...help?

I haven't gone beyond 1.7ghz since my last reset, I did when I first got the phone but my assumption is that s new kernel was installed that changed the way the CPU ramped up (Exynos btw) to counter the battery life claims. In all honesty from my limited knowledge it's probably the GPU that limits the frame rate but that's only a guess as 8 cores @ 1.7ghz is plenty of processing power.

The S9+ is not rooted, so it's on stock kernel.
Also, the emulator (mame) is designed to only use Cpu for 2d games, with Gpu used at minimum.
1.7 is far from enough, especially when it can go up to 2.7 to improve the otherwise non-optimal performance of the games. I'm very curious what's the issue here...

Yea mine is stock as well - my observation was that in the first month or so I had hit 2.7 a fair amount, but haven't in the last 2 months once so assuming they modified the stock kernel

Oh, now i understand. Well, it's very strange and frankly, a bit alarming. Could anyone else with up to date stock software share some numbers as well?
Same.
Same here on G965FXXU2BRG6.
Edit: It seems that CPU Spy doesn't work correctly on the S9. When using CPU-Z and running Geekbench 4, I can clearly see CPUs 4-7 running at 2704 MHz at times.
That's interesting. So my next test will have to involve Cpu-z as a monitoring tool. Thanks for the replies guys.
We need a cristal clear answer on this.

Ran Antutu on S9+ Snapdragon last night, it's being throttled down to a max. of 1.77MHz and no more even during antutu's 15 minutes Stress Test. It would score much higher if it was allowed to.
...an error, please remove.

God damn it. Haven't got the time to do further testing myself yet, but by the looks of it 1.7 seems to be the max. and not 2.7.
Any rooted phones owners care to share some numbers? Can you lock it to 2.7 like it should?
Are we talking Exynos or Snapdragon here? That'd be a good piece of info while sharing the stats!
Personally i'm talking about exynos, but apparently snapdragon behaves the same.

Post#9 was about Snapdragon
Has anyone tried hitting the "Performance mode" toggle in the drop down menu? Stupid question, but easily overlooked.

Yes, i tried all settings including performance mode. It only affects brightness and screen resolution. The Cpu speed is still limited to a 1.7 max.

I did the same, then I tried in WQHD+ resolution hoping that it may create more demand from CPU/GPU and no, same 1.7. What is the best way to make a complaint about it to Samsung? We bought an 8 cylinder Maserati and after the honeymoon they remotely disabled two because the engine might blow?

Probably the official forums.
It would be great if a rooted user with a Cpu oriented kernel (overclocking, voltage, governor manipulation) would show us that those big cores can, at least when rooted, be used at full potential.

Thanks, am gonna register there, see what they have to say about it. That and my other question I'd have: why I received my 'new' S9+ with IMEI SV 07? And when I did IMEI lookup on line, found out that the phone was registered for warranty one month before I ordered it. My email to Customer Service was returned with "Samsung sells only brand new phones". Didn't know that there is no replacement policy at Samsung, you can only return it for refund, it's not a good option for me, because I took that 'bundle deal' and I don't owe the Chromebook anymore, they would subtract some$ from it. Well, according to Samsung, the warranty on my phone runs until October '19, we'll see.
