This series completes the support of MSIs for ACPI guest featuring an ITS. 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
