When randr notices a crtc configuration request for a slave device, it checks if the slave allocated pixmap exists and is suitable, if not it allocates a new shared pixmap from the master, shares it to the slave, and starts the master tracking damage to it, to keep it updated from the current front pixmap. If the resize means the crtc is no longer used it will destroy the slave pixmap. This adds the concept of a scanout_pixmap to the randr_crtc object, and also adds a master pixmap pointer to the pixmap object, along with defining some pixmap helper functions for getting pixmap box/regions. v2: split out pixmap sharing to a separate function. v3: update for void * Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
