3d driver for the spica

[Framp]

The file I've uploaded above is already in the official i5700 update. (It's already in the kernel-making vmware image under i5700.2/modules/g3d)
This driver is already being used on our phone.

We need to look for something else. This will not going nowhere.. damn..

I actually fail at understanding what is missing on our phone right now to have a decent 3d experience.
I mean, a modification of s3c_g3d.c?
Something else? I've really no idea :/

What's missing is the operating system taking advantage of the chip, the graphics are not sent to it. It's just not utilized.

What's needed is a driver that can take API calls, put them to the chip and output them correctly back to the OS.

[Framp]

Oh yeah it's in use and the code looks also a lot like the one in the odroid git xD

OK, but to make the system take advantage of the chip do we have to modify the s3c_g3d module or something else?
It looks like an interesting platform to hack on!

the s3c_g3d looks like a manager..

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...

From what i heard Samsung is not going to do anything about 3D at all. But this split on two parts is a generic model of linux video drivers because you should not do complex tasks in kernel space due to timing and security concerns. It's not correlated with openness of driver itself.

[Framp]

Does anybody know where the other part of the 3d driver is kept?

Nice, and the libraries are closed source right? I mean the libgles*.so


If yes, the best thing - as a noob - would be to try to port this: http://sourceforge.net/projects/omnia2gl/


also having open source drivers (from qualcomm maybe?) would help a lot

Тут в англ. ветке (Open GL drivers - programmer motivation) писали про возможность собрать деньги на разработку 3д драйверов.
Я в этих вопросах не слишком силен, но не могут ли эти люди нам помочь с этим: Тестирование портативного процессора S3C6410
P.s.: написал сюда т.к. хреново знаю англ ,а там ветка EN

Probably it does help, but anyway writing and debugging HW drivers on the production device such as phone is unbelievably painfull and hard. Someone with devboard required.

I did some research, and it looks like that the upcoming Galaxy 3 alias GT-I5800 has the same CPU as the Spica. I extracted the EGL libraries and did some MD5 hash check on the files.
Firmwares: I5800: I5801BVJE8 vs. I5700: I570EXXJE4

61606e4427204c8e07c61cb5c47a1e18 *libGLESv2_fimg.so I5700

libGLES_android.so is the same in both firmwares

So it looks like the I5800 has a different (newer?) driver. The I5800 has a display resolution of 240 x 400 pixels, this can be the reason for the difference.
Anyway, the driver is not working for Spica (tried it but no go.)
Any thoughts on this?

Some other interesting things: the I5800 has Flash Player, FM radio, Touchwiz UI and Live Wallpapers. Somebody with skills should check these out.
