I wrote a change to vm-bhyve[1] to be able to pass the options to bhyve
in the correct order to use GPU passthru. In the incorrect order, bhyve
will return an error. The question was raised: Is it expected that
bhyve will return an error depending upon the order of command-line
arguments, or should it be handling this scenario?
The issue is when "-s 31, lpc" is presented to bhyve. If it is passed
prior to "-o pci.0.31.0.pcireg.vendor=host", then there is no error.
However, if it is in the opposite order, this is returned:
$ bhyve ... -o pci.0.31.0.pcireg.vendor=host -s 31,lpc ...
pci slot 0:31:0 already occupied!
I will be updating my PR to make things a bit easier regardless of the
answer, but it would be nice to know if this is intended or not.
Thank you.
