Name

drm_atomic_set_fb_for_plane — set framebuffer for plane

Synopsis

void drm_atomic_set_fb_for_plane (struct drm_plane_state * plane_state,
 struct drm_framebuffer * fb);
 

Arguments

plane_state

atomic state object for the plane

fb

fb to use for the plane

Description

Changing the assigned framebuffer for a plane requires us to grab a reference to the new fb and drop the reference to the old fb, if there is one. This function takes care of all these details besides updating the pointer in the state object itself.
