Is there any discussion on HDCP on the summit? It is tightly
coupled with HDMI and DVI and should be managed together with the
transmitter. But there is not code to handle HDCP in DRM/FB/V4L in
latest kernel. Any thoughts on HDCP? Or you guys think there is risk
to support it in kernel? Thanks

What I did for the GMA500 is to use the GTT to do scrolling by rewriting
the framebuffer GTT tables so they work as a circular buffer and doing a
bit of alignment of buffers.

Goal: Sharing an EDID parser between DRM/KMS, FBDEV and V4L2.
The DRM EDID parser is currently the most advanced implementation and will
be taken as a starting point.

Hello everybody,
First of all, I would like to thank all the attendees for their participation
in the mini-summit that helped make the meeting a success.
Here are my consolidated notes that cover both the Linaro Connect meeting and
the ELC meeting. They're also available at
