hw/arm/smmuv3: Queue helpers
...
We introduce helpers to read/write into the command and event
circular queues.
smmuv3_write_eventq and smmuv3_cmq_consume will become static
in subsequent patches.
Invalidation commands are not yet dealt with. We do not cache
data that need to be invalidated. This will change with vhost
integration.

hw/arm/smmuv3: Wired IRQ and GERROR helpers
...
We introduce some helpers to handle wired IRQs and especially
GERROR interrupt. SMMU writes GERROR register on GERROR event
and SW acks GERROR interrupts by setting GERRORn.
The Wired interrupts are edge sensitive hence the pulse usage.

hw/arm/smmu-common: IOMMU memory region and address space setup
...
We set up the infrastructure to enumerate all the PCI devices
attached to the SMMU and create an associated IOMMU memory
region and address space.
Those info are stored in SMMUDevice objects. The devices are
grouped according to the PCIBus they belong to. A hash table
indexed by the PCIBus pointer is used. Also an array indexed by
the bus number allows to find the list of SMMUDevices.
