From: Joshua Ashton Date: Tue, 10 Jan 2023 22:50:42 +0000 (+0000) Subject: drm/amd/display: Fix COLOR_SPACE_YCBCR2020_TYPE matrix X-Git-Tag: baikal/aarch64/sdk5.9~139 X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=a00c3bb368c061cdd912dca7c22cc325767f16d7;p=kernel.git drm/amd/display: Fix COLOR_SPACE_YCBCR2020_TYPE matrix commit 973a9c810c785ac270a6d50d8cf862b0c1643a10 upstream. The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is missing the values for the fourth column of the matrix. The fourth column of the matrix is essentially just a value that is added given that the color is 3 components in size. These values are needed to bias the chroma from the [-1, 1] -> [0, 1] range. This fixes color being very green when using Gamescope HDR on HDMI output which prefers YCC 4:4:4.
