sample: vfio bochs vbe display (host device for bochs-drm)
Display device, demo-ing the vfio dmabuf display interface (VFIO_GFX_PLANE_TYPE_DMABUF). Compatible enough to qemu stdvga that bochs-drm.ko can be used as guest driver. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

+ 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.
+ Device looks a lot like "qemu -device secondary-vga".
