+         Build a virtual display sample driver for use as a VFIO
+         mediated device.  It supports the region display interface
+         (VFIO_GFX_PLANE_TYPE_DMABUF).
+         Emulate enough of qemu stdvga to make bochs-drm.ko happy.
+         That is basically the vram memory bar and the bochs dispi
+         interface vbe registers in the mmio register bar.
+         Specifically it does *not* include any legacy vga stuff.
