From 80f690e9e3a60f628de61748be4dd2fd6baf5cc8 Mon Sep 17 00:00:00 2001 From: Jyri Sarha Date: Mon, 19 Feb 2018 22:28:23 +0200 Subject: drm: Add optional COLOR_ENCODING and COLOR_RANGE properties to drm_plane MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a standard optional properties to support different non RGB color encodings in DRM planes. COLOR_ENCODING select the supported non RGB color encoding, for instance ITU-R BT.709 YCbCr. COLOR_RANGE selects the value ranges within the selected color encoding. The properties are stored to drm_plane object to allow different set of supported encoding for different planes on the device. v2: Add/fix kerneldocs, verify bitmasks (danvet) Cc: Harry Wentland Cc: Daniel Vetter Cc: Daniel Stone Cc: Russell King - ARM Linux Cc: Ilia Mirkin Cc: Hans Verkuil Cc: Uma Shankar Cc: Shashank Sharma Reviewed-by: Ville Syrjälä Signed-off-by: Jyri Sarha [vsyrjala v2: Add/fix kerneldocs, verify bitmasks] Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180219202823.10508-1-ville.syrjala@linux.intel.com Acked-by: Harry Wentland Reviewed-by: Daniel Vetter --- include/drm/drm_color_mgmt.h | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'include/drm/drm_color_mgmt.h') diff --git a/include/drm/drm_color_mgmt.h b/include/drm/drm_color_mgmt.h index 03a59cbce621..b3b6d302ca8c 100644 --- a/include/drm/drm_color_mgmt.h +++ b/include/drm/drm_color_mgmt.h @@ -26,6 +26,7 @@ #include struct drm_crtc; +struct drm_plane; uint32_t drm_color_lut_extract(uint32_t user_input, uint32_t bit_precision); @@ -37,4 +38,22 @@ void drm_crtc_enable_color_mgmt(struct drm_crtc *crtc, int drm_mode_crtc_set_gamma_size(struct drm_crtc *crtc, int gamma_size); +enum drm_color_encoding { + DRM_COLOR_YCBCR_BT601, + DRM_COLOR_YCBCR_BT709, + DRM_COLOR_YCBCR_BT2020, + DRM_COLOR_ENCODING_MAX, +}; + +enum drm_color_range { + DRM_COLOR_YCBCR_LIMITED_RANGE, + DRM_COLOR_YCBCR_FULL_RANGE, + DRM_COLOR_RANGE_MAX, +}; + +int drm_plane_create_color_properties(struct drm_plane *plane, + u32 supported_encodings, + u32 supported_ranges, + enum drm_color_encoding default_encoding, + enum drm_color_range default_range); #endif -- cgit
