G= PU passthrough might not work properly. > bhyve: gvt_d_setup_gsm: Unknown IGD device. It's not supported yet!: No s= uch file or directory > bhyve: gvt_d_init: Unable to setup Graphics Stolen Memory > Device emulation initialization error: No such file or directory First of all, GPU passthrough is not supported by bhyve. It's an experiment= al feature. So far, bhyve only handles GPU passthrough for Intels integrated graphic devices. Therefore, it uses a list of device IDs [1] to determine which qui= rks to apply to a given GPU. Your Intel Arc GPU isn't in this list, so it errors out with "Unknown IGD device". [1] https://github.com/freebsd/freebsd-src/blob/9b0102837e305ca75de2bc14d284f78= 6a33f9a6a/usr.sbin/bhyve/amd64/pci_gvt-d.c#L155 > Resizable BAR is activated in UEFI - this Intel ARC GPU card needs it. SR= V-IO is activated as well. As a counter example: when I passthrough my onb= oard-NIC, bhyve works as expected. bhyve doesn't support resizable BAR. IIRC, it can cause issues when activat= ed for an passthrough device. --=20 You are receiving this mail because: You are the assignee for the bug.=
