[PATCH v2 2/4] bhyve: add support for setting fbuf resolution

Roman Bogorodskiy bogorodskiy at gmail.com
Tue Sep 22 12:28:49 UTC 2020


From: Fabian Freyer <fabian.freyer at physik.tu-berlin.de>

The resolution of the VNC framebuffer can now be set via the resolution
definition introduced in 5.9.0.

Also, add "gop" to the list of model types  the <resolution/>
sub-element is valid for.
