[v3 00/14] Add HDR Metadata Parsing and handling in DRM layer

[v3 00/14] Add HDR Metadata Parsing and handling in DRM layer

[Uma Shankar]

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.

Note: It took a while to float this version as there was no userspace
consumer for it and dependency on full userspace stack. However, things
are falling in place now. Media driver and VAAPI changes for HDR are
already out, with compositors changes also expected to land soon.

[v3 01/14] drm: Add HDR source metadata property

[Uma Shankar]

This patch adds a blob property to get HDR metadata
information from userspace. This will be send as part
of AVI Infoframe to panel.

v2: Rebase and modified the metadata structure elements
as per Ville's POC changes.

[v3 09/14] drm/i915: Write HDR infoframe and send to panel

[Uma Shankar]

Enable writing of HDR metadata infoframe to panel.
The data will be provid by usersapace compositors, based
on blending policies and passsed to driver through a blob
property.

v2: Rebase

v3: Fixed a warning message

[v3 10/14] drm/i915: [DO NOT MERGE] hack for glk board outputs

[Uma Shankar]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

This is to limit PORT C on GLK to drive only
HDMI. Not sure if this is mandatory, this is just
to test HDR on GLK HDMI.
