In linux kernel since version 3.10 (release Date: 2013-06-30)
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".
