 # The display service v2: a pluggable scanout backend
 
+**Status: complete (V1–V6).** The compositor boots on the GOP framebuffer and, when a
+virtio-gpu driver announces itself, hot-attaches a native backend over the shared `shm`
+scanout surface — with runtime mode-setting, EDID, and fenced (vsync) presents, and it
+re-attaches across driver restarts. All serial-gated (see [display-v2-plan.md](display-v2-plan.md)).

 v1 ([display.md](display.md)) is a compositor that owns the **GOP framebuffer** — it
 composites a layer stack into a cacheable back buffer and streams damage to the linear
 framebuffer the firmware handed over. That path is portable and good: it drives any GPU,
