Subject: [PATCH 0/6] drm/i915/dp: Support for DP HDR outputs
Date: Fri, 23 Aug 2019 04:34:55 +0300	[thread overview]
Message-ID: <20190823013501.14256-1-gwan-gyeong.mun@intel.com> (raw)

Support for HDR10 video was introduced in DisplayPort 1.4.
On GLK+ platform, in order to use DisplayPort HDR10, we need to support
BT.2020 colorimetry and HDR Static metadata.
It implements the CTA-861-G standard for transport of static HDR metadata.
It enables writing of HDR metadata infoframe SDP to the panel.
The HDR Metadata will be provided by userspace compositors, based on
blending policies and passed to the driver through a blob property.
And It refactors, renames and extends a function which handled vsc sdp
header and data block setup for supporting colorimetry format.
And It attaches the colorspace connector property and HDR metadata property
to a DisplayPort connector.

These patches tested on below test environment.
Test Environment:
 - Tested System: GLK and Gen11 platform.
 - Monitor: Dell UP2718Q 4K HDR Monitor.
 - In order to test DP HDR10, test environment uses patched Kodi-gbm,
   patched Media driver and HDR10 video.

   You can find these on below.
