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

In your status page only about 30 of 52 are done. It's just 60%. And without fully working this driver we can't expect any working textures in games. Even angry birds are mostly without them. And as i understand quality of video depends on FIMG drivers as they are base of all graphics in android. Or i'm not right? I think there should be any hardware acceleration.

I don't think there are any developers left here with g3 phone. If they are they've already made a fully working ports.

So i expect my phone die with 2.2

The status page just lists implemented OpenGL ES features. They are not of equal importance. All the most important ones are already implemented. This translates to about 90% of typical usage of OpenGL ES API.

Angry Birds is not the best example here, because it has missing textures not because of an unimplemented feature, but rather because of the way of managing texture memory in OpenFIMG, which needs improvement for cases where more memory is needed than is available (Angry Birds is an example of such case).

As for video, I will repeat again, OpenFIMG is not responsible for video processing in any way. There is a dedicated set of hardware devices on S5P6442 which can do it - hardware encoder/decoder (FIMV-MFC) and video postprocessor and scaler (FIMV-PP).

AFAIK the video playback is fully working on CM7. I don't know if it works on CM9, but it should be fully working on CM7 which is really what we should be targetting with the Galaxy 3. Not even Google wants ARMv6 phones on ICS because there's just so much more that ICS wants to do that is too much for the ARMv6 core to handle. We may have a very late ARMv6 based processor that may share a lot with the S5PV210 (The Galaxy S processor) but that doesn't change the fact the CPU is tiny. Really tiny.

Yes. I agree that video works on cm7. But quallity is awfull. And also cm7 works faster than 2.2. But why is quality in cm7 worse than in 2.2?
I understand that ics+ needs more resources than our phone has. But 2.3 is much faster than 4.0+ and even 2.2.

I don't know if it's usefull or not but here is the samsung fimg sources (for spica, probably (very) old)

With OpenFIMG in its current status, it isn't of much use. All of the hardware functionality supported by those sources is already implemented in OpenFIMG, so for learning about the hardware reading sources of OpenFIMG and available hardware documentation will be a much better choice. In addition those sources are stripped down from shader compiler (which was buggy and slow anyway), so there isn't any new information there.

OpenFIMG is mostly missing several high-level parts, like texture memory swapping (which would be made redundant after using CMA to allocate texture memory), decompression of compressed textures unsupported by the hardware and some OpenGL ES extensions, all of which don't touch the hardware too much.

What do you mean by 'quality is awful'? Colours wrong? Pixelated? Glitchy? I don't understand.

Pixelated

D@rekills4 · Mar 19, 2013

I certainly don't see any pixelation in videos.
But I can say that the FPS at which the videos are played is quite low for 360p videos. 240p works just fine.

videos are glitchy, framerates are a bit low not as smooth as they wer in froyo, and and they are pixelated the videos dont look smooth as in froyo kinda like n smooth borders hard edges and a bit low clored. this is not a complaint plz dont take it wrongly. i have a suggestion too...... y dont we better use old sam drivers until the open fimg thingy is completely fixed.

Haven't I already said that OpenFIMG is _NOT_ responsible for video playback in any way. Video is fully handled by OpenCORE or OpenMAX on Android and they use completely different hardware than the FIMG-3DSE GPU handled by OpenFIMG.

Please at least read the last page (not even several last pages, which would be even better) before posting something that has been already said to be incorrect.

OpenFIMG is used in CM7 to remove the need to replace a big part of Android graphics stack with code from Android 2.2, because the one in 2.3 relies on functionality broken in old drivers. It is even more important in further CM versions for G3, because you can't transplant graphics stack from Android 2.2 to Android 4.x, so OpenFIMG is the only way to get hardware acceleration.

Sounds like the video is being decoded at the wrong resolution. Best bet is to not watch many videos on the Galaxy 3. It hasn't got a great video accelerator to start with.

Well I got very good playback on YouTube with HD enabled when I was on 8.3 with the 1GHz #888 kernel. Flash that kernel it might work.

Well, I consider the state of OpenFIMG acceptable already. Games have never been a target of this project and problems with videos you mentioned have nothing to do with OpenFIMG - there is a separate video codec hardware, for which there is simply no driver for newer ROMs (there was some work done in enabling it in CM7, but I'm not sure what happened with it).

If you still want those games so badly, there is a lot of skilled developers on xda-developers and I don't believe there is no one that could fix those remaining problems. At this time I don't have any plans for doing it myself. I have work, studies, home, my other personal projects (mostly mainline Linux support for hardware platforms I have at home), which already occupy most of my time and I'd like to still find some to rest from all of that.

I have a long term plan to add OpenGL ES 2.0 support (including a shader compiler) to OpenFIMG as a part of my Master's thesis ("Shader code generation and optimization for Samsung FIMG-3DSE GPU") and also migrate G3D module to the Direct Rendering Manager subsystem and mainline it, but this is going to take a lot of time and it shouldn't be expected earlier than in next year. I doubt someone will be still using a G3 at that time (but this is my personal project, so this is not a problem).

i will definitely have g3 nxt yr
Am never gonna sell it irrespective of whether i get a new phone or not

You know, G3 dev on XDA has taught mee one thing.....

Never to give up and how to make the best use of what we have
i wud hav never imagined six toggles,brightness bar,swipe to remove on Froyo (hats off to all froyo dev) and the hardwrk of marcel (Which is worth saluting)

(SORRY 4 BEING a LITTLE OFF TOPIC AND philosophical)

do further development is needed such that playing games on GB ROM would become possible
