Hello Jan,
I'm afraid I will have to ask for a bit of clarification there. My
understanding of a frame buffer is an area of (usually video) memory
representing the image shown on a screen. You can have more or less as
many of those as will fit into video memory and flip between them. You
can also have up to 32 virtual screens (the hardware supports 64).
Regards
Michael

Hi Michael,
sorry for hijacking the thread, but can I ask if there will be (or even
better - is already)
support for MORE framebuffers?
I still see it as nice feature for more broader audience then me only :)
For example as tooling solution for development multihead devices.

Hello All,
I am mainly asking this out of curiosity and interest. On Linux as
of X.Org 1.19 we no longer maintain the user-space vboxvideo driver
(it does not play well with non-root X.Org or with Wayland) and
instead wrote a drm/kms driver which works with the X.Org
modesetting driver and GNOME Shell. I was wondering whether any
non-Linux developers have had a look at the source yet, since I know
that a number of other systems have ported drm drivers from Linux.
The source code in our tree for the Linux drm/kms driver for
vboxvideo is located at
src/VBox/Additions/linux/drm/
See the make files and the file files_vboxvideo_drv for details of
all the files involved (I am still trying to simplify it). It
builds unchanged against Linux 3.11 to Linux 4.10 inclusive, which I
hope would simplify porting, and I would be happy to make any
changes to our in-tree sources which are not problematic for Linux
and are helpful for other systems (even if you carry your own
sources it would probably be helpful if what we provide is as close
to yours as possible).
Regards
Michael
