This adds support for reverse prime to the modesetting driver. Reverse prime is where we have two GPUs in the display chain, but the second GPU can't scanout from the shared pixmap, so needs an extra copy to the on screen pixmap. This allows modesetting to support this scenario while still supporting the USB offload one. v1.1: fix comment + ret = bits (Eric) Reviewed-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
