Hi,

I did'nt know about this Pyra project, look like a very nice little toy !

As we started to discuss with Tony on another email thread :

- etnaviv is used for the GC320 composition core, and is for 2D acceleration only. The open source Xorg driver I'm working on enable composition and XVideo acceleration using etnaviv kernel driver and is mainly benefical for desktop environment and applications.

- Tomi is working on a SGX driver that will be closed source for legal purpose, but that will enable OpenGLES 3D acceleration in conjonction with Xorg driver through DRI3.

All of this is in alpha state, but usable. You can already try the open source part, but we need to work with Tomi on the 3D part a little more.

I looked at your website but cannot find precise information about the omap5 soc : which chip do you use ?

Regards

OK cool.

Oh OK I did not know SGX is somehow involved too. Is the plan to
use them both at the same time?

Personally I was hoping to avoid any SGX binaries and still have
usable graphics with etnaviv as SGX binaries are dependant on
specific kernel versions..
