| D | display-manager.rst | 90 Pixel blend mode is a DRM plane composition property of :c:type:`drm_plane` used to
92 background plane (bg). Here, we present main concepts of DRM blend mode to help
97 Basically, a blend mode sets the alpha blending equation for plane
115 DRM has three blend mode to define the blend formula in the plane composition:
125 and pre-multiplied is the default pixel blend mode, that means, when no blend
128 provides a set of subtests to verify plane alpha and blend mode properties.
130 The DRM blend mode and its elements are then mapped by AMDGPU display manager
144 multiplied (true/false), being only true for DRM pre-multiplied blend mode.
145 :c:type:`mpcc_alpha_blend_mode` defines the alpha blend mode regarding pixel
153 blend formula, as follows:
