I'm currently trying to set up a BSP for a Congatec QA3 board with an Intel
Atom E3845.
The goal is to have an image with nothing more than a console and OpenGL via
EGL.
So no X11 or DirectFB.
I'm a bit confused regarding the support for this configuration. On the
intel site I found
http://www.intel.com/content/www/us/en/embedded/software/emgd/emgd-driver-epog-atom-e3800-linux-user-guide.html
that mentions the EMGD driver. On the Yocto site there is a BSP called
Intel Atom Processor E3800 with Open Source Graphics (Valley Island). Is it
possible to have accelerated h264 en-/decoding and OpenGL support with the
valley island solution or is this restricted to the EMGD driver. If the
later is the case, what's the reason to remove EMGD support as it seems the
case
(https://lists.yoctoproject.org/pipermail/meta-intel/2014-September/002477.html).
The "EMGD" driver covers many devices, depending on what version
you're referring too. The driver that was removed from meta-yocto
supports the SGX-based Atom boards (Tunnel Creek, iirc) and is
unmaintained. Luckily you're using a modern Atom with Intel HD
graphics, which is supported by the open-source drivers in the
standard kernel and Mesa, so that Valley Island BSP should work just
fine.

Thanks for the reply.
So the open source driver fully supports quick sync and opengl in
hardware as well?
If yes I guess using gstreamer and mesa packages, right?
