The patch is available here http://blog.polvorin.com.ar/patches/pvfb.patch
is an attempt at supporting the virtual framebuffer on xen guest
( http://wiki.netbsd.org/projects/project/xen-domu-pvfb/ )
Basic functionality is in place, but reached a point where guidance/feedback would be very welcome in order to push this forward,
this is the first piece of kernel code I attempt to write, and I'm not
that familiar with netbsd to start with.
Need to review, at least
* Memory management (conversion to frame number to pass references to xen host). Currently save/restore isn't working, but neither do it without this patch on my install.
* code just act as a kind of adapter between xenbus and genfb, wskbddev and wsmousedev, letting them attach to xenbus. Is that the way to go?
* The way I added the drivers to be used by autoconf
There is a little bit more description at http://blog.polvorin.com.ar/2016/04/20/netbsd-pvfb.html
