https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D223837 Bug ID: 223837 Summary: vmm/amd: IVHD entries are not applied to the device table Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: avg@FreeBSD.org The AMD-Vi support code does parse IVHD entries in IVRS table. The entries are stored in softc->dev_cfg[] of the ivhd driver. But that information is never applied to a device table. For instance, see tables 92, 93, 94 in the AMD IOMMU specification. Those define the location of the DTE setting field in 4-byte IVHD entries and the meaning of bits in it. And then see table 7 on how those bits should be translated to bits in an actual Device Table Entry corresponding to a device described in the IVHD entry. --=20 You are receiving this mail because: You are the assignee for the bug.=
