[v4 00/12] Add HDR Metadata Parsing and handling in DRM layer

[v4 00/12] 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.

v4: Addressed Shashank's review comments.

Note: Media driver and VAAPI changes for HDR are already out, with compositors
changes also expected to land soon.

[v4 03/12] drm: Parse Colorimetry data block from EDID

[Uma Shankar]

CEA 861.3 spec adds colorimetry data block for HDMI.
Parsing the block to get the colorimetry data from
panel.

v2: Rebase

v3: No Change

v4: Addressed Shashank's review comments. Updated
colorimetry field to 16 bit as DCI-P3 got added
in CEA 861-G spec, as pointed out by Shashank.

[v4 07/12] drm: Enable HDR infoframe support

[Uma Shankar]

Enable Dynamic Range and Mastering Infoframe for HDR
content, which is defined in CEA 861.3 spec.

The metadata will be computed based on blending
policy in userspace compositors and passed as a connector
property blob to driver. The same will be sent as infoframe
to panel which support HDR.

v2: Rebase and added Ville's POC changes.

v3: No Change

v4: Addressed Shashank's review comments and merged the
patch making drm infoframe function arguments as constant.

[v4 08/12] 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

v4: Addressed Shashank's review comments

[v4 09/12] 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.

[v4 10/12] drm/i915: Add HLG EOTF

[Uma Shankar]

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

ADD HLG EOTF to the list of EOTF transfer functions supported.
Hybrid Log-Gamma (HLG) is a high dynamic range (HDR) standard.
HLG defines a nonlinear transfer function in which the lower
half of the signal values use a gamma curve and the upper half
of the signal values use a logarithmic curve.

v2: Rebase

v3: Fixed a warning message

I haven't really looked at this series in depth, but just a quick
drive-by comment:  it doesn't look like this patch touches i915, so the
"drm/i915:" headline prefix should probably just be "drm:" and you might
want to move it earlier in the series so that all the core patches come
before all the i915 patches.

Sure Matt, will update this as part of next version.

I don't see where this is used, am I missing something? You attach the property
to the connector, I don't see how the planes get involved in the end.

Further down in the patch the member is called hdr_output_metadata_property and I cannot
find where hdr_source_metadata_property is defined in drm_mode_config. Does this patch
even compile?

Should the metadata_type enum be a more global structure, and not HDMI specific, but only
the first value gets assigned to HDMI_STATIC_METADATA_TYPE1 ?

Hi Liviu,
Yes currently it's not linked to plane, but I am planning to add a property interface which tells
userspace what underlying hardware planes are capable of HDR. For now, this is not used and
I can drop it to avoid any confusion. Will be sending out the plane capability property for HDR
pretty soon (most probably along with next version of this series).

Regards,
Uma Shankar
