Applications explicitly request the creation of frame + * buffers through the DRM_IOCTL_MODE_ADDFB(2) ioctls and receive an opaque + * handle that can be passed to the KMS CRTC control, plane configuration and + * page flip functions. + * + * Frame buffers rely on the underlying memory manager for allocating backing + * storage. When creating a frame buffer applications pass a memory handle + * (or a list of memory handles for multi-planar formats) through the + * struct &drm_mode_fb_cmd2 argument. For drivers using GEM as their userspace + * buffer management interface this would be a GEM handle. Drivers are however + * free to use their own backing storage object handles, e.g. vmwgfx directly + * exposes special TTM handles to userspace and so expects TTM handles in the + * create ioctl and not GEM handles. + * + * Framebuffers are tracked with struct &drm_framebuffer. They are published + * using drm_framebuffer_init() - after calling that function userspace can use + * and access the framebuffer object. The helper function + * drm_helper_mode_fill_fb_struct() can be used to pre-fill the required + * metadata fields. + * + * The lifetime of a drm framebuffer is controlled with a reference count, + * drivers can grab additional references with drm_framebuffer_reference() and + * drop them again with drm_framebuffer_unreference(). For driver-private + * framebuffers for which the last reference is never dropped (e.g. for the + * fbdev framebuffer when the struct struct &drm_framebuffer is embedded into + * the fbdev helper struct) drivers can manually clean up a framebuffer at + * module unload time with drm_framebuffer_unregister_private().
