Is there any summary for this summit or presentation material? I am looking forward for some idea on CEC. It is really complex in functionality. Maybe other guys is expecting simiar fruite from summit too.
Yes, there will be a summit report. It's not quite finished yet, I think.
With respect to CEC we had some useful discussions. It will have to be a new class of device (/dev/cecX), so the userspace API will be separate from drm or v4l.
This is a repeat of a comment from the KS discussion: what about using the socket API instead of a device node ?
And the kernel will have to take care of the core CEC protocol w.r.t. control and discovery due to the HDMI 1.4a requirements.
I plan on starting work on this within 1-2 weeks.
