[Xen-devel] Re: collecting info on platforms with VT-d BIOS problems
Hi Allen,
thanks for taking care of this!
You may already know those two (we have been in contact regarding the
P6T before, you provided me a beta bios that worked around this):
1)
(a) Asus P6T Deluxe
(b) all (except you provided beta BIOS) including latest 1904
(c) all (even with iommu_include_reserved)
(d) xm dmesg shows:
(XEN) Command line: dom0_mem=1024M iommu=1 iommu_include_reserved=1
...
