Documentation

Mode object ID of the &drm_framebuffer this plane should scan out.

When a KMS client is performing front-buffer rendering, it should set
FB_ID to the same front-buffer FB on each atomic commit. This implies
to the driver that it needs to re-read the same FB again. Otherwise
drivers which do not employ continuously repeated scanout cycles might
not update the screen.
