Here are relevant links on how is used on illumos : https://movementarian.org/blog/posts/2018-10-26-pci-pass-through-support-wi= th-bhyve-and-smartos/ https://www.cyber-tec.org/2019/05/29/using-bhyve-pci-passthrough-on-omnios/ I think it would be nice to have this feature on FreeBSD jails, as Mark sta= ted=20 "better solution would be to extend pci(4) so that bhyve can use it to do everything required for PCI passthrough." I would like to explore this option any pointer on how to start would be re= ally good. --=20 You are receiving this mail because: You are the assignee for the bug.=
