hi, looking into enabling SR-IOV on X79, to use with GPU, though it’s mostly NIC results from searching.
there’s no option in bios, but it ought to be supported. maybe it’s enabled together with vt-d.
looking through x99 bios there are options, but none in x79, maybe the modules could be ported.
looking up the chipsets, only vt-d is mentioned.
using AMIBCP 5.02.0031 i can find this:
(0190) SR-IOV Support
(0191) If system has SR-IOV capable PCIe Devices, this option Enables or Disables Single Root IO Virtualization Support.
(1414) SR-IOV Support
(1415) Enable or disable the SR-IOV support
(1418) SR-IOV SystemPageSize
(1419) SR-IOV SystemPageSize
using UEFITool i find this:

which i was able to match with the following from MMTool, which is what i’d use to extract and patch:
