Title:
RFE: Implement support for SMBIOS Type 41 structures
Status in QEMU:
In Progress
Bug description:
This was originally filed in Fedora bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=669955
"""
Please extend the existing support for SMBIOS in qemu to add a capability to
provide "Onboard Devices Extended Information" (Type 41). Not only is this
replacing one of the existing types, but it also provides a mapping between
devices and physical system chassis locations. But there is no physical
chassis! Right. However, this doesn't mean you don't want to tell the guest OS
which virtual (e.g. network) interface is which. You can do that, if you
implement this extension that is already going into real hardware, and likely
other VMs too.
See also page 117 of the v2.7 of the SMBIOS spec.
FWIW, VMware ESX and Workstation expose their PCI NICs in the PCI IRQ Routing
Table. Kind of odd the first time you see it with biosdevname, as your NIC
becomes pci3#1, but that's "correct" from a BIOS perspective. :-)
