Documentation

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.
