[PATCH 0/6] qtests/libqos: Introduce pci-arm


From: Eric Auger
Subject: [PATCH 0/6] qtests/libqos: Introduce pci-arm
Date: Mon, 10 Jan 2022 22:19:09 +0100

Up to now the virt-machine node only contains a virtio-mmio
driver node but no driver that eventually produces any pci-bus
interface.

Hence, PCI libqos tests cannot be run with aarch64 binary.

This series brings the pieces needed to be able to run PCI tests
with the aarch64 binary: a generic-pcihost driver node gets
instantiated by the machine. This later contains a pci-bus-arm
driver which produces a pci-bus interface. Then all tests
consuming the pci-bus interface can be run with the libqos arm
virt machine.

One of the first goal was to be able to run the virtio-iommu-pci
tests as the virtio-iommu was initially targetting ARM and it
was awkard to be run the test with the pc machine. This is now
possible.

Only the tests doing hotplug cannot be run yet as hotplug is
not possible on the root bus. This will be dealt with separately
by adding a root port to the object tree.

Best Regards

Eric
