It needs relocation in memory. Does anybody know how to solve this?

Yes, libacc.so is already prelinked to that address.
I compiled a non prelinked libacc for you so that adress should be free now, but i dont expect it to work anyway

Changed libacc.so but EGL fails with the same error

**alex86dee** · 07-04-2010, 11:45 PM

works, but the difference is not visible.

isn't it the same driver used in 1.5 after all?

I'm going to try writing an OpenGL ES 1.1 implementation from scratch based on S3C6410 documentation found on the net. I don't know if time allows me to finish it, but i have already read all the needed papers and i'm starting the work today. So anybody here experienced in OpenGL, especially from hardware/driver side, is welcome to help.

well that sounds great!

hopefully we will get good gfx.

@tom3q: Excellent, can't wait to see the product! What previous experience do you have with drivers?

**DE_NISKA** · 07-05-2010, 08:35 PM

Maybe this module will help - s3c_fimg3d.c
POST-TECH LXR - kernel-2.6.29-sdio/drivers/media/video/samsung/g3d/s3c_fimg3d.c

I had ported Linux to several devices before, including reverse engineering the hardware and original drivers. Not much experience in Open GL, though, but after reading OpenGL ES specification and S3C6410 documentation it seems doable.

I have got the module already, i guess it will need some refactoring, but it's only a helper for the main driver. Anyway thanks for your interest.
