Original commit message:
Initial bhyve native graphics support.
This adds emulations for a raw framebuffer device, PS2 keyboard/mouse,
XHCI USB controller and a USB tablet.
A simple VNC server is provided for keyboard/mouse input, and graphics
output.
A VGA emulation is included, but is currently disconnected until an
additional bhyve change to block out VGA memory is committed.
Credits:
- raw framebuffer, VNC server, XHCI controller, USB bus/device emulation
and UEFI f/w support by Leon Dang
- VGA, console/g, initial VNC server by tychon@
- PS2 keyboard/mouse jointly done by tychon@ and Leon Dang
- hypervisor framebuffer mem support by neel@
Tested by: Michael Dexter, in a number of revisions of this code.
With the appropriate UEFI image, FreeBSD, Windows and Linux guests can
installed and run in graphics mode using the UEFI/GOP framebuffer.
