Hello Harry,
Many of us in the mail chain have discussed this before, on what is the right
way to blend and tone map a SDR and a HDR buffer from same/different color
spaces, and what kind of DRM plane properties will be needed.
As you can see from the previous comments, that the majority of

## Introduction
We are looking to enable HDR support for a couple of single-plane and
multi-plane scenarios. To do this effectively we recommend new interfaces to
drm_plane. Below I'll give a bit of background on HDR and why we propose these
interfaces.
