[v5,00/13] Add HDR Metadata Parsing and handling in DRM layer

Message

Shankar, Uma March 11, 2019, 3:57 a.m. UTC

This patch series enables HDR support in drm. It basically defines
HDR metadata structures, property to pass content (after blending)
metadata from user space compositors to driver.

Dynamic Range and Mastering infoframe creation and sending.

ToDo:
1. We need to get the color framework in place for all planes
   which support HDR content in hardware. This is already in progres
   and patches are out for review in mailing list.
2. UserSpace/Compositors: Blending policies and metadata blob
   creation and passing to driver. Work is already in progress
   by Intel's middleware teams on wayland and we should be getting
   the initial version pretty soon for review.

Please review and share your feedbacks/suggestions.

Note: The intention for these patches is to get a design feedback on
the uapi changes, generic property design and infoframe handling.
This cannot get merged as of now without the userspace support in place.

A POC has already been developed by Ville based on wayland. Please refer
below link to see the component interactions and usage:
https://lists.freedesktop.org/archives/wayland-devel/2017-December/036403.html

v2: Updated Ville's POC changes to the patch series.Incorporated cleanups
and fixes from Ville. Rebase on latest drm-tip.

v3: Fixed a warning causing builds to break on CI. No major change.

v4: Addressed Shashank's review comments.

v5: Rebase on top of Ville's infoframe refactoring changes. Fixed non modeset
case for HDR metadata update. Dropped a redundant patch.

Note: Media driver and VAAPI changes for HDR are already out, with compositors
changes also expected to land soon. Some discussions have already started with
initial design on weston in community and is in active development along
with GL efforts.
