[v11 00/12] Add HDR Metadata Parsing and handling in DRM layer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 the patches for
   the same are in review.

A POC has already been developed by Ville based on wayland. Please refer
below link to see the component interactions and usage:

v7: Squashed 2 patches, dropped 1 change and addressed Brian Starkey's and
Shashank's review comments.

v8: Addressed Jonas Karlman review comments. Added Shashank's RB to the series,
fixed a WARN_ON on BYT/CHT.

v9: Addressed Ville and Jonas Karlman's review comments. Added the infoframe
state readout and metadata reference count.

v10: Addressed review comments from Jonas and Ville. Dropped one patch related
to i915 fastset handling as per Ville's feedback.

v11: Addressed Ville's review comments.

Note: v9 version is already tested with Kodi and a confirmation from team kodi has been
