Subject: [RFC RESEND PATCH 0/4] hw/arm/virt-acpi-build: Introduce iommu option for pci root bus
Date: Sat, 27 Feb 2021 08:33:47 +0000 [thread overview]
Message-ID: <1614414831-39712-1-git-send-email-wangxingang5@huawei.com> (raw)
From: Xingang Wang <wangxingang5@huawei.com>
These patches add support for configure iommu on/off for pci root bus,
including primary bus and pxb root bus. At present, All root bus will go
through iommu when iommu is configured, which is not flexible.
So this add option to enable/disable iommu for primary bus and pxb root bus.
When iommu is enabled for the root bus, devices attached to it will go
through iommu. When iommu is disabled for the root bus, devices will not
go through iommu accordingly.
Xingang Wang (4):
pci: Add PCI_BUS_IOMMU property
hw/pci: Add iommu option for pci root bus
hw/pci: Add pci_root_bus_max_bus
hw/arm/virt-acpi-build: Add explicit idmap info in IORT table
