	Hello.

I am wondering about one thing: I do not know devices inside of for
example odroid c2, but when configuring the amlogic kernel, you have:
a vpu device
a ge2d driver
a vout/osd driver and logo driver
and encoders/postprocess managers/whatever
What it corresponds to in the display controller patch that is being
integrated at this time?

Hi Micha?,

The Amlogic Kernel implements the video pipeline out of the DRM/KMS and v4l frameworks, and
must handle much more uses cases like Video Encoding, Video Capture, ....

The DRM patch integrates the equivalents of amlogic modules : vpu, vout, osd, postprocess managers
The ge2d is not used yep, and encoders will be used to encoder video but will be used with the v4l framework.

So what is missing? ge2d, v4l support maybe? I do not count mali, not
sure what is the chance of supporting mali.
Also what is vpu and what is ge2d? I was always interested in what is
what but no info
ahh and hdmi is not supported, I know
