Ok, I just tested 4.0.0-rc8.
(XEN) ACPI: HPET id: 0xffffffff base: 0xfed00000
(XEN) [VT-D]dmar.c:371: Invalid ACPI DMAR entry length: 0x0
(XEN) Failed to parse ACPI DMAR. Disabling VT-d.
No 30 second delay anymore, VT-d gets disabled immediately.
And with iommu=verbose:
(XEN) ACPI: HPET id: 0xffffffff base: 0xfed00000
(XEN) [VT-D]dmar.c:679: Host address width 36
(XEN) [VT-D]dmar.c:371: Invalid ACPI DMAR entry length: 0x0
(XEN) Failed to parse ACPI DMAR. Disabling VT-d.
So both seem to work as expected with this broken BIOS.
Thanks!
