It generates an ACPI IORT table which describes the IO relationship between the root complex and the ITS. This typically enables vhost-net support on such guest. The series applies on top of Drew's series: [PATCH 0/2] couple ITS support fixups, which is now on target-arm.next. Original contribution was sent by Prem Mallapa in [PATCH v2 9/9] [optional] arm: smmu-v3: ACPI IORT initial support, part of [PATCH v2 0/9] SMMUv3 Emulation support. https://lists.gnu.org/archive/html/qemu-devel/2016-08/msg04350.html Prem's 1st integration targetted Root Complex - vSMMU relationship description whereas this series targets RC - ITS description. This was tested with a v4.8 guest + rebased Tomasz' series: - [PATCH V11 0/8] Introduce ACPI world to ITS, https://lkml.org/lkml/2016/9/12/926 History: v1 -> v2: - addressed Drew's comments, see individual patches Prem's version -> v1: - split into 2 separate patches - iort struct field names match include/acpi/actbl2.h 's ones - added ITS node - added ID mapping in RC node - removed smmu mode Prem Mallappa (2): ACPI: Add IORT Structure definition ARM: Virt: ACPI: Build an IORT table with RC and ITS nodes hw/arm/virt-acpi-build.c | 73 ++++++++++++++++++++++++++++++++++++++------- include/hw/acpi/acpi-defs.h | 68 +++++++++++++++++++++++++++++++++++++++++ 2 files changed, 130 insertions(+), 11 deletions(-) -- 2.5.5
