Question regarding OpenGL 2.1 support and Xorg

Thu Nov 2 11:45:47 UTC 2017

Now replying to the correct email thread.

Thanks for your reply...

Meanwhile, yesterday I was able to progress a bit with this... I have
compiled mesa-17.2.4 with the etnaviv code replaced with the latest from
mesa git repo, thus enabling OpenGL 2.1.

I was able to login into Ubuntu Desktop 17.10 with wayland, however the GUI
is still too heavy for GC3000. I saw no noticeable performance improvement
or degradation when comparing with the 2D unit and xf86-video-armada driver.

Regarding Xorg I found out that the graphical display is initialized, but
no image can be seen because the imx-drm driver of mesa doesn't provide the
DRI interface. It seems also possible to integrate VDPAU or VAAPI with
imx-drm and the video acceleration unit of i.MX6. That would be pretty
nice, but I think it would require lots of work. I also believe that the
codec acceleration unit is not completely open-source... if it was, it was
just a matter of creating a wrapper for the VDPAU API.

Xorg logs follow below.

Regards,
Luís
