Subject: [RFC v2 0/6] drm/i915/dp: Preliminary support for DP YCbCr4:2:0 outputs
Date: Thu, 21 Feb 2019 21:27:25 +0200 [thread overview]
Message-ID: <20190221192731.27095-1-gwan-gyeong.mun@intel.com> (raw)
On Gen 11 platform, to enable resolutions like 5K@120 (or higher) we need
to use DSC (DP 1.4) or YCbCr4:2:0 (DP 1.3 or 1.4) on DP.
In order to support YCbCr4:2:0 on DP we need to program YCBCR 4:2:0
to MSA and VSC SDP.
This patches are RFC patches that add a VSC structure for handling
Pixel Encoding/Colorimetry Formats and program YCBCR 4:2:0 to MSA and VSC SDP.
This is currently not tested, but I wanted to get some inputs on this approach.
The idea of a scaling (RGB -> YCbCr4:4:4 -> YCbCr 4:2:0) is to follow the
same approach used in YCbCr 4:2:0 on HDMI.
v2: Addressed Maarten's review comments, fixed minor coding and block comment
style. And reordered a first patch ("drm/i915/dp: Support DP ports
YUV 4:2:0 output to GEN11") as a last patch.
Gwan-gyeong Mun (6):
drm/i915/dp: Add a config function for YCBCR420 outputs
drm: Add a VSC structure for handling Pixel Encoding/Colorimetry
Formats
drm/i915/dp: Program VSC Header and DB for Pixel Encoding/Colorimetry
Format
drm/i915/dp: Add a support of YCBCR 4:2:0 to DP MSA
drm/i915/dp: Update pipe_bpp for DP YCbCr4:2:0 outputs
drm/i915/dp: Support DP ports YUV 4:2:0 output to GEN11
