[Qemu-devel] [PATCH 0/2] ACPI IORT generation for ITS support

From: Eric Auger
Subject: [Qemu-devel] [PATCH 0/2] ACPI IORT generation for ITS support
Date: Thu, 13 Oct 2016 12:55:41 +0200

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

It generates an ACPI IORT table which describes the 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 [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.

Prem's 1st integration targetted Root Complex - vSMMU relationship
description whereas this series targets RC - ITS description.

This was tested with a guest featuring Tomasz' series related to ACPI ITS
and PCIe support:
- [PATCH V11 0/8] Introduce ACPI world to ITS,
- Support for ARM64 ACPI based PCI host controller,


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
