Blob property which contains the set of buffer format and modifier pairs supported by this plane. The blob is a struct drm_format_modifier_blob. Without this property the plane doesn't support buffers with modifiers. Userspace cannot change this property. Note that userspace can check the &DRM_CAP_ADDFB2_MODIFIERS driver capability for general modifier support. If this flag is set then every plane will have the IN_FORMATS property, even when it only supports DRM_FORMAT_MOD_LINEAR. Before linux kernel release v5.1 there have been various bugs in this area with inconsistencies between the capability flag and per-plane properties.
