[Qemu-devel] [PATCH 0/4] vga: new display devices

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This patch series adds new display devices.

Number one is secondary-vga.  That is identical to VGA (aka -vga std),
except that it doesn't occupy all the legacy vga stuff (ioports, memory
window @ 0xa0000), so you can have more than one of these in the system.
It has one pci memory bar for the framebuffer and one mmio bar for
registers.  OVMF can drive it.  Doesn't use it as console for some
reason, but initializes it and the linux kernel will see it as efifb.
Cutting edge linux kernels can drive it too (bochs-drm driver in 3.14+).

Number two is virtio-gpu-pci.  That is the virtio graphics card written
by Dave Airlie.  Only 2d for now, 3d support is to be tackled later on.

Linux kernel driver:

  http://cgit.freedesktop.org/~airlied/linux/log/?h=virtio-vga-3d

Number three is virtio-vga.  That is virtio-gpu-pci with all the vga
compatibility fluff added.  Firmware builder has cutting edge
seavgabios.git packages which include a virtio vgabios for it, see
  http://www.kraxel.org/repos/

cheers,
  Gerd
