I understand this this. At the same time I think pv dom0 does exactly this blind mapping. I also tried to map these regions as read-only and that worked. Can be this an option for these ram regions? I also asked this question on usb-linux mailing list and received similar to yours reply: https://www.mail-archive.com/linux-usb@xxxxxxxxxxxxxxx/msg55128.html > > > (XEN) 00000000f8000000 - 00000000fc000000 (reserved) > > (XEN) 00000000fec00000 - 00000000fec01000 (reserved) > > (XEN) 00000000fed00000 - 00000000fed04000 (reserved) > > (XEN) 00000000fed1c000 - 00000000fed20000 (reserved) > > (XEN) 00000000fee00000 - 00000000fee01000 (reserved) > > (XEN) 00000000ff000000 - 0000000100000000 (reserved) > > (XEN) 0000000100000000 - 000000041ee00000 (usable) > > > (XEN) [VT-D]dmar.c:788: Host address width 39 > > (XEN) [VT-D]dmar.c:802: found ACPI_DMAR_DRHD: > > (XEN) [VT-D]dmar.c:472: dmaru->address = fed90000 > > (XEN) [VT-D]iommu.c:1136: drhd->address = fed90000 iommu->reg = > > ffff82c000201000 > > (XEN) [VT-D]iommu.c:1138: cap = c0000020660462 ecap = f0101a > > (XEN) [VT-D]dmar.c:383: endpoint: 0000:00:02.0 > > (XEN) [VT-D]dmar.c:802: found ACPI_DMAR_DRHD: > > (XEN) [VT-D]dmar.c:472: dmaru->address = fed91000 > > (XEN) [VT-D]iommu.c:1136: drhd->address = fed91000 iommu->reg = > > ffff82c000203000 > > (XEN) [VT-D]iommu.c:1138: cap = d2008020660462 ecap = f010da > > (XEN) [VT-D]dmar.c:397: IOAPIC: 0000:f0:1f.0 > > (XEN) [VT-D]dmar.c:361: MSI HPET: 0000:f0:0f.0 > > (XEN) [VT-D]dmar.c:486: flags: INCLUDE_ALL > > (XEN) [VT-D]dmar.c:807: found ACPI_DMAR_RMRR: > > (XEN) [VT-D]dmar.c:383: endpoint: 0000:00:1d.0 > > (XEN) [VT-D]dmar.c:383: endpoint: 0000:00:1a.0 > > (XEN) [VT-D]dmar.c:383: endpoint: 0000:00:14.0 > > (XEN) [VT-D]dmar.c:676: RMRR region: base_addr d5e6b000 end_address > > d5e91fff > > (XEN) [VT-D]dmar.c:807: found ACPI_DMAR_RMRR: > > (XEN) [VT-D]dmar.c:383: endpoint: 0000:00:02.0 > > (XEN) [VT-D]dmar.c:676: RMRR region: base_addr d7000000 end_address > > df1fffff > > So there are at least some RMRRs here.
