From: Ville Syrjälä <ville.syrj...@linux.intel.com> BT.2020 specifies two YCbCr<->RGB conversion formulas. The more traditional non-constant luminance and a more complicate constant luminance one. Add an enum value for the constant luminance variant as well in case someone has hardware supporting it.
v2: Reduce the enum name to fit within the 31 character uapi limit Cc: Harry Wentland <harry.wentl...@amd.com> Cc: Daniel Vetter <dan...@ffwll.ch> Cc: Daniel Stone <dan...@fooishbar.org> Cc: Russell King - ARM Linux <li...@armlinux.org.uk> Cc: Ilia Mirkin <imir...@alum.mit.edu> Cc: Hans Verkuil <hverk...@xs4all.nl> CC: Uma Shankar <uma.shan...@intel.com> Cc: Shashank Sharma <shashank.sha...@intel.com> Cc: Jyri Sarha <jsa...@ti.com> Signed-off-by: Ville Syrjälä <ville.syrj...@linux.intel.com> Acked-by: Harry Wentland <harry.wentl...@amd.com> #v1 --- drivers/gpu/drm/drm_color_mgmt.c | 1 + include/drm/drm_color_mgmt.h | 3 ++- 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/drm_color_mgmt.c b/drivers/gpu/drm/drm_color_mgmt.c index 4ff064623836..cc28c32399af 100644 --- a/drivers/gpu/drm/drm_color_mgmt.c +++ b/drivers/gpu/drm/drm_color_mgmt.c @@ -358,6 +358,7 @@ static const char * const color_encoding_name[] = { [DRM_COLOR_YCBCR_BT601] = "ITU-R BT.601 YCbCr", [DRM_COLOR_YCBCR_BT709] = "ITU-R BT.709 YCbCr", [DRM_COLOR_YCBCR_BT2020] = "ITU-R BT.2020 YCbCr", + [DRM_COLOR_YCBCR_BT2020_CONST] = "ITU-R BT.2020 YCbCr const", }; static const char * const color_range_name[] = { diff --git a/include/drm/drm_color_mgmt.h b/include/drm/drm_color_mgmt.h index b3b6d302ca8c..175943c87d5b 100644 --- a/include/drm/drm_color_mgmt.h +++ b/include/drm/drm_color_mgmt.h @@ -41,7 +41,8 @@ int drm_mode_crtc_set_gamma_size(struct drm_crtc *crtc, enum drm_color_encoding { DRM_COLOR_YCBCR_BT601, DRM_COLOR_YCBCR_BT709, - DRM_COLOR_YCBCR_BT2020, + DRM_COLOR_YCBCR_BT2020, /* non-constant luminance */ + DRM_COLOR_YCBCR_BT2020_CONST, /* constant luminance */ DRM_COLOR_ENCODING_MAX, }; -- 2.13.6 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
