3d driver for the spica

[Framp]

EDIT:-

1) Tom3q (our saviour =) is currently working on new 3d driver. He's rewriting it from scratch.
STATUS: Status - gles6410 - Current project status. - Project Hosting on Google Code
The driver will become useful after all the things from Basic EGL and Basic OpenGL sections get implemented
The driver is still not out. The drivers will be released when it's finished. You will notice a new thread when the driver is ready.
Let him work.

2) De Niska (thank you for your work!) has modified the original samsung driver
STATUS: complete (this is not the 3d driver, just a mod)
Multiupload.com - upload your files to multiple file hosting sites!

Archive contains last source and update package.

WARNING!!:
1. Update will change your kernel to modified LK2.09.4
2. Update will change egl libraries to compatible only with kernel from p1
3. Im not tested it on games. maybe rendering errors.
4. It can be unstable also
5. It not have blackscreen bug (now wakeup after sleep)

If you brick your spica do not ask me how to recover!

The main problems are missing 3d features in certain applications (such as missing colors in speedx for example) and the inability to wake up the phone once it's in sleep mode.
You can find these drivers (which are not intended for normal use) reading the whole thread or in the first post here: http://forum.samdroid.net/f9/samdroid-turbo-1301/

These two drivers/project are completely unrelated

I'd like to remind everyone that we are in the DEVELOPMENT section so stupid questions already asked should not go here.
If you spam this thread it will be hard to find the right informations.

So please, if it's not something related to the driver, STFU

FAQ:
Q. Why new 3D driver?
A. Samsung original one sucks.

Q. Who make the new 3D driver?
A. Tom3q, and you can follow his work at gles6410 - Project Hosting on Google Code

Q. When will it be released?
A. No schedule right now. New driver built on top of Samsung's junk is not easy.

Q. What can you expect from the new driver?
A. Since it's not released yet, we can at best IMAGINE that it would be JUST BETTER than the original one.

Q. How much does the new driver cost?
A. ZIP!!!! But you can donate if you really want to.

Q. What do the developers want most from this thread?
A. Just stop spaming this thread and wait patiently, please.

Thanks for your attention.


[Discussion/Feedback/Bug reports] 3d driver for the Spica

Original Post:
Hello
On the net (SmartQ MID Unofficial Board • View topic - SmartQ OpenGL ES) I've read about a device with our cpu which is able to have 3d acceleration using the hardware accelerator. The smartq has a mali gpu but the test (which has been deleted on youtube) used the samsung chip.
The driver may be this one: odroid development center: Linux kernel for ODROID: 코드 저장소
but I don't actually know how this may be useful to you.

Thanks for everything
Best regards

Привет.
В сети (SmartQ MID Unofficial Board • View topic - SmartQ OpenGL ES) я прочел о устройстве с нашим процессором, который использован 3D аккселерацию при помощи аппаратного ускорителя. В SmartQ стоит mali GPU, но в тесте (который уже удалили с YouTube) использовался чип от Samsung.
Драйвер может быть отсюда: odroid development center: Linux kernel for ODROID: 코드 저장소
Но по правде говоря я не знаю поможет это вам или нет.
Спасибо за все
С наилучшими пожеланиями.

Thanks for this post. Some time ago (1 week) git was down. Now we could do smth with it.

P.S> This is better translation of your post:

P.P.S> How can I copy just 1 directory from the git?

Ya can't =) But cloning the whole git just takes a couple of minutes anyway.

Yes but, it's faster to copy-paste these 3 files from the git browser

By the way, anyone have a clue on how to compile this driver?
I think I will need the vmware dev image, put the driver in the kernel source and compile.
The makefile adds the drivers to the list of "things to compile"..
And I think we have to modify the Kconfig so that it "depends on CPU_S3C6410"

In the end we should add the resulting drivers to system/lib/egl/
and modify subsequently the egl.cfg

Damn, I'll download that image as soon as I will get a decent internet connection :P
Does anybody have the vmware image already and could try this out?

An alternative could be to download the odroid release and rip out the compiled driver, I think..

(http://groups.google.com/group/odroi...020c73321adeb# I've asked the odroid developers and they said it's not possible. But I think we should try it.)

(3D Drivers for S5PC110 - odroid developer discuss | Google Groups I've asked the odroid developers and they said it's not possible. But I think we should try it.)

The git browser that you link to seem awfully broken to me, the includes are cut in half for example. Anyway you'd probably really need to compile the whole kernel and change stuff so that it is recognized properly as a driver for s3c6410 and blacklist/remove whatever old driver there might be. I'm not very into kernel hacking (certainly not android) and I don't even own a android phone yet so I won't be of any help

Anyway I doubt it will work (especially considering what the guy at odroid says), the references to s3c64xx might quite possibly be from an older effort. I guess they switched odroid to s5pc110 and used the old attempts as a base.
Still all is not lost, if the s3c6410 makes it into other linux based phones/devices there might be future efforts to bring 3D to it. It probably all comes down to what Samsung has in store for the chip...

[Framp]

You have to copy the html code from the git browser
The git browser does not sanitize the code and (given that an include is defined as #include <random/include>) the browser parse the <random/include> as a tag.

I agree on the need of recompiling the whole kernel and if some of our kernel hackers could help it would be very much appreciated
I'm neither into kernel hacking but I'll try to understand something this summer - I have to prepare an exam right now -.-

By the way I don't think samsung will ever write other drivers for that chip: they have a policy to support only new phones
I've always had samsung phones and I always used hacks to enable cool things

Oh, and I believe the driver wasn't written by the odroid developers but by samsung ones.
It makes sense since the odroid developers buy samsung chips and want support.

I suppose you're right

Once again, anything you can find for the Linux kernel is not a real 3D driver. It's just a bridge to pass data between hardware and Android's OpenGL implementation. So sources for /system/lib/egl with support for s3c6410 should be found and they should support/provide accelerated OpenGL API for particular Android version. I've not seen yet any. You could try to download Android Eclair sources from Samsung and search for libraries with interfaces to s3c_g3d kernel module.

[Framp]

Isn't the OpenGL API already implemented? I believe OpenGL support was already there (in fact we are able to run OpenGL on our device but it's slow because everything is software rendered)

Don't we miss just the bridge to make the phone use the 3d accelerator?

I've uploaded the driver if somebody want to check this out :P

s3c_g3d.zip

Edit: omg, the developer who is replying me on the odroid developer is Justin Lee - and I suppose is the one who has written the driver. Damn and he said it couldn't work -.- Edit2: or maybe not, there are quite a lot justin lee at samsung

So what you are saying is that Samsung is going for the same binary-blob approach as Nvidia right? Meaning they release a GPL compatible interface to connect their proprietary driver with the linux kernel.
That sucks...

The OpenGL API is there but you have to implement it against the hardware, right now it's only implemented in software. Just like Mesa.
