https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D279729 Bug ID: 279729 Summary: virtualization/bhyve: we are forced to passthru the whole IOMMU group of a GPU and not the single slots. Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: marietto2008@gmail.com Hello. My GPU has one integrated USB controller. It is the RTX 2080 Ti and FreeBSD detect 4 slots : 02:00.0 VGA compatible controller: NVIDIA Corporation TU102 [GeForce RTX 20= 80 Ti] (rev a1) 02:00.1 Audio device: NVIDIA Corporation TU102 High Definition Audio Contro= ller (rev a1) 02:00.2 USB controller: NVIDIA Corporation TU102 USB 3.1 Host Controller (r= ev a1) 02:00.3 Serial bus controller: NVIDIA Corporation TU102 USB Type-C UCSI Controller (rev a1) So I tried to passthru only the slots 2 and 3,because I don't need to pass = the GPU itself and / or the audio slot (2/0/1),like this : -s 8:2,passthru,2/0/2 \ -s 8:3,passthru,2/0/3 \ This is what happened : Assertion failed: (mr->name =3D=3D memp->name), function unregister_mem, fi= le /usr/src/usr.sbin/bhyve/mem.c, line 344. If we want to passthru only one or two slots (like only the audio or the USB controller) that are inside the whole IOMMU group and not the whole IOMMU group,we can't do it. Can this behavior be fixed ? --=20 You are receiving this mail because: You are the assignee for the bug.=
