-Subject: [PATCH] qxl: alloc & use shadow for dumb buffers
-
-This patch changes the way the primary surface is used for dumb
-framebuffers. Instead of configuring the bo itself as primary surface
-a shadow bo is created and used instead. Framebuffers can share the
-shadow bo in case they have the same format and resolution.
-
-On atomic plane updates we don't have to update the primary surface in
-case we pageflip from one framebuffer to another framebuffer which
-shares the same shadow. This in turn avoids the flicker caused by the
-primary-destroy + primary-create cycle, which is very annonying when
-running wayland on qxl.
-
-The qxl driver never actually writes to the shadow bo. It sends qxl
-blit commands which update it though, and the spice server might
-actually execute them (and thereby write to the shadow) in case the
-local rendering is kicked for some reason. This happens for example in
-case qemu is asked to write out a dump of the guest display (screendump
-monitor command).
