Open source driver for FIMG 3DSE (GPU of Galaxy 3)

I am posting here as I am not allowed to do so in development subforum.
Anyway, I am the developer of the OpenFIMG project (formerly GLES6410), which is aiming to provide proper OpenGL support on devices with FIMG 3DSE 3D engine, found in S3C6410, S5PC100 and probably also in S5P6442. The project is in a pretty advanced state as it is already capable of running Android 2.3 with hardware acceleration. Still many OpenGL extensions and some core features (like lighting) are still missing. More info can be found here: https://github.com/tom3q/openfimg/wiki.
It is very likely (and almost confirmed) that the SoC used in Galaxy 3 (S5P6442) contains the same GPU as the one in S3C6410, which is the chip inside Galaxy Spica and similar phones, at least basing on what Quadrant and GLbenchmark show and on GL libraries supposed to be dumped from Galaxy 3.
What I am trying to say is that my project may also be useful on Galaxy 3, but I am the only developer working on it and I am doing it in my free time, so it does not progress as fast as one may expect. In other words, I am looking for some other developers interested in this project.
If you are interested, then do not hesitate to drop me a PM.
Mod EDIT : moving this to development
EDIT: Attached some documents about FIMG 3DSE (based on S3C6410 documentation and my reverse engineering)
EDIT: The project has been successfully used on G3. Builds of ICS for G3 use OpenFIMG as primary graphics driver currently and there are update packages for CM7.

Very interesting .. I send you PM.

Galaxy 3 has no GPU.

Based on what?
All my sources state that it has exactly the same FIMG 3DSE rev. 1.5 as in S3C6410.

Based on the fact that no site says that the I5800 has a GPU and that graphics on games are really laggy.
Unless you are not talking about a discrete GPU.

No mobile phone contains a discrete GPU. All of them are embedded inside some SoC chip, some are better (SGX, Adreno), some are worse (FIMG 3DSE).
It is exactly the same as with Spica and similar phones. Games are laggy because the hardware is not a speed daemon and the performance is even more impacted by really _broken_ drivers.

Then why nobody write that it has GPU like all the other phones like Galaxy S ,Nexus S etc?

Because it is a low end phone, software support for this GPU is very bad and the GPU itself is not a speed daemon.

Okay..so your project involves developing real good drivers so that even the g3 low end gpu can perform better, right?

Yes. Of course, it will not work on par with Adreno 200 or similar GPUs, but should at least work a bit better. The main target is to run Android 2.3 (and future versions, which will not work will original drivers, because of missing extensions) with full hardware acceleration and without bugs found in Samsung drivers.

Hmmm.. Nice .. Good luck with your project.. One of our devs marcellusbe is working on porting CM7 to G3.. This would surely help him ..
Sent from the 3rd Galaxy !

cool... if so this is gonna make new benchmark .. pun intended ... best of luck man.... I had thought of throwing this phone a long time back but you guys always give hopes... and ofcourse result..

Wow interesting!
This should be moved to dev section I have sent a PM to haree

Cool. So what can others help with?

Too interesting
I'ld like to help with whatever i can

I'll back you up in spirit, sorry,i know nothing about programming

VERY intresting!
and yes the galaxy 3 does have a gpu and yes it has been confirmed (or atleast i heard) that it has this gpu..cant wait to see the outcome!

Actually, I will need some people who would compile, test and eventually fix the code for Galaxy 3, because the only phone with this GPU I have is a Galaxy Spica (i5700) and there may be some subtle differences between them. (Especially in the kernel part, where kernel modules may require changing of some addresses or some other fragments of code.)
Preferably, I would like someone to help me with the project, but I understand this is not an easy task, so not everyone can apply.

I don't mind being a tester
Edit: also will we be able to play gameloft games and nfs shift?

Nice, thanks.
However, you have to understand that it is not a simple drop-in replacement of standard GL libs. This project replaces the whole graphics subsystem of the phone, including some kernel modules and this makes testing a bit more complicated as it needs pretty big modification of the phone software.
If it is not a problem for you then ok.

It all depends if all the extensions required by these games will get implemented. Also, there may be some problems with screen resolution of Galaxy 3, which is a not standard one. I cannot give any claims regarding the performance as the real performance of this hardware is unknown.

Exynos 5250 and Tegra 4

Yes I've used the search tool and the last post in the last Exynos 5250 thread was at december 2011 and I can't find any rules about reviving old threads so I don't want to fiddle with it since I might get an infraction or worse a ban and and the last Tegra 4 thread wasn't coherent enough for me.
I don't know all the details but I would like to start talking about the supposed new Exynos 5250 and Tegra 4 development so please bear with me, I need all of those who has reliable information to add in the discussion. I'd like to start things with how will it fare against this year's smartphones and tablets? specifically the Samsung Galaxy S3 (1.4 ghz Quad ARM Cortex-A9 + Exynos 4412 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) and HTC one X ( 1.5 GHz quad-core ARM Cortex-A9 + Nvidia Tegra 3 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) since they are currently the top Phones out there in the market performance wise.
Further into the topic will the new Exynos and Tegra make their predecessors completely obsolete once they come out? or is the performance leap going to be minimal at best? due to various factors perhaps you can't fully utilize their potential due to the limiting software apps out there? What I want you guys to elaborate for the community is how better will it be in terms of CPU and GPU benchmark performance. Please do share your Ideas and any reliable information about the said topic at hand.
P.S. I just got an SGS3 my very first smartphone and android, did I make a huge mistake by buying it or should have I gone for a cheaper Galaxy Nexus and waited for the new Exynos to come out?

what better than Nvidia Tegra 3

First off, let's talk processors:
Your phone, the SGS3 i9300 is packing the Quad-Core Exynos 4412, rather than the dual-core Snapdragon S4 (MSM8960) for North American versions of the SGS3. The international version of the HTC One X has the 1.5GHz Tegra 3 vs the North American version which has the S4 as well.
Performance wise, these processors are all pretty on-par. Benchmark scores are close, with the Tegra 3 gaining the upper hand graphics-wise with its 12-core GPU. The processor to look out out of these 3 would be the S4, considering it's the first processor to (kinda) take advantage of the A15 cortex.
...The reason I say kind of, is because there is some discussion on the S4 being a hybrid between the A9 cortex (Tegra 3, Exynos 4) and the beastly A15. Qualcomm is a rebel, and doesn't follow ARM's chip designs like the others do. But I digress...
A15 is going to be a HUGE improvement over A9. HUGE performance gains, higher resolution displays, USB 3.0,OpenGL ES 3.0 (depending on the GPU) and much much more. The dual-core Exynos 5250 is going to be based off the A15 cortex, and it's going to blow even the quad core A9's out of the water. Tegra 4 will almost definitely be based off A15 as well, and it's going to be a sight to see. As for the Snapragon S5, who knows? I'm sure Qualcomm has some cool stuff up it's sleeve.
To answer your question, yes the new Exynos and Tegra processors are going to make older generation processors obsolete, but that doesn't mean you made a bad choice. The SGS3 is a great phone, and as such has tons of developers making custom roms, kernals, and other fun hacks to keep you occupied for the months to come hack away!
hope that helped!

You didn't make a mistake as at present android is not able to push current quadcore devices to their limits and there is a scope for lot more improvement
So even though next gen processors will be lot more powerful, your phone will still be able to handle next android releases so Don't worry and enjoy your S3

Android already has full multi core support. The only thing holding back multi cores is the fact that many apps still don't make use of them.
Also, that other guy made some great points but forgot to mention S4 Pro, which we already know a good deal about and is very impressive. It sets the bar high for the next tegra and for exynos 5250.

They're not going to be "completely obsolete" (even GN and SG2, for example, are still good phones despite being "last year") but there is going to be a large performance increase to A15.
There's always a next big thing coming out, but generally it's not worth waiting for unless you're on the cusp. Even if the generation you shop is relatively old, the competitive market (unlike, say, that of a fruity company) helps to compensate you by providing discounts of the previous tech.
S3, in particular, is a darn good phone no matter how you look at it (except that it has hardware buttons, but I digress..)

[Q] HELP Deciding Galaxy S2 i727 Skyrocket vs. Galaxy S2 i777

Hello guys, so I recently sold my Atrix 4G and have been on the dilemma on which phone to get... I am currently looking at these 2 models:
Galaxy S2 Skyrocket (i727) | (Qualcomm MSM8260 Snapdragon - Dual-core 1.5 GHz Scorpion - Adreno 220)
Galaxy S2 (i777) | (Exynos C210 - Dual-core 1.2 GHz Cortex-A9 - Mali-400MP)
From what I have read seems like the i777 features the best performance CPU/GPU compared to the i727 but I would like to know by what margin, will it be noticeable? (Performance is very important for my occasional gaming).
Also I like my phones to be backed by the community with lots of rom's to choose from (CM10 is a must for me) and from the 2 I'd like to know which is the most future proof and offers the biggest developer crowd? NFC Support is a must!
Other opinions are welcome!
Also on a side note should I just fork the extra bucks and get a Gnex? I like the community support offered for it but the camera and lack of external Sd-Card just doest cut it for me. Also how does the CPU/GPU of this one compares to the skyrocket?
Thanks!
Oscar

1. The Exynos dual SCREAMS, especially when compared to the Snapdragon S3. If the Skyrocket had a Snapdragon S4, then you'd have a decision, but trust me, after owning the Sprint GSII and the Evo 3D (Exynos and Snapdragon S3, respectively, I can tell you that for gaming and everyday performance, hands down the Exynos is the winner in every category. The Adreno GPU in the S3 is terrible for any high-end gaming (Grand Theft Auto 3, Dead Trigger, etc). I myself game heavily on my phone, and I'll tell you straight up, the Exynos dual very powerful and still very viable.
2. The Galaxy S II i777 has NFC, though no Secure Element. What does that mean? It means you can't use Google Wallet, but you can do pretty much anything else, like Android Beam and NFC Tag interaction.
3. The i777 is identical to the i9100P (i9100 with NFC), except for the button layout. You'll get much more support than with the Skyrocket.

It's an older phone. That's how I'll summarize it. The chipset is fast but not fast enough to play the latest and greatest smoothly.

Would nook hd/ + handle those games? Since it does have a powervr sgx544 gpu?

A possible Source for exynos files?

Hey guys,
just thought bout the good old exynos 4 chipset and got reminded about the nexus 10, that uses an exynos 5 chipset.
So here my though, if there are enough similarities between exynos 4 and 5, why not use some source code (e.g. for graphics, since its still mali graphics) and implent it into cm10.1? If we finally could achieve some breaktroughs on one exynos device, every other would also make profit of this, like galaxy s2, s3, note 2, note and many other devices.
If someone is good enough at coding, give a try, cause sammy still havent hand out all the necessery files, to make cm run fluid on the exynos platform.
cheers

[PORTING DISCUSSION] Cherry picks from Exynos based devices on SGS4

Hi,
Everyone is shouting, we will not support Galaxy S4 (I9500) since it is having Exynos which lacks the documentation and sources. Yes, I know that sucks. I would say, we are not really getting super awesome ROMs like CM, MIUI anytime soon. But how if we think differently?
There are many Exynos based devices which have got pretty stable builds of CM and MIUI (e.g. Note 2).. Even Nexus 10 is based on Exynos.
Well, I am not that good but learning to port stuff from here and there.. How if we pick up some of the sources from Exynos devices like Nexus 10, Note 2 etc. and make them work on SGS4?
World will be beautiful again, isn't it?
I might be totally wrong so I expect you to explain stuff rather than ranting over this thread Let's help each other.. What say?
Regards,
Rahul Patil. :good:

It would be incredibly difficult and in my opinion, not worth the effort.
The Nexus 10 utilises Exynos 5250 while the Note 2 uses Exynos 4***(I forgot, 4410,I think), the S4 i9500 uses Exynos 5410 which is different as you can see.
However, some developers will doubtlessly pick up development for the Exynos variant (Faryaab already has an unofficial cm build for the i9500).
For all that effort, cm on the i9500 shall never be as stable and functional as that on the Snapdragon variants.

Well, yes.. Unless and until Samsung releases Exynos documentation and sources. Well, I don't know if there is any chance of getting documents. At least Samsung Exynos replied to one of my tweets regarding releasing sources. They said, they are working on licensing stuff and it should be resolved soon. But you know, their "soon" can be like 2-3 years more too.

Intl GS2 and Note1 are Exynos 4210
Intl GS3 and Note2 are Exynos 4412
Nexus 10 is Exynos 5250 - Mali T604 GPU
I9500 is Exynos 5410 - PowerVR GPU and MANY other differences from the 5250
In short, almost none of the Exynos4 stuff is useful, and most likely neither is most of the Nexus10 stuff

A vast majority of IP blocks are the same as on the 5250 so there is a lot one can pick from there.
Stupid question; weren't most of the CM problems related with the 2D accelerator and not the GPU itself?
