pviommu is an IOMMU driver that interacts with pKVM paravirtualized
IOMMU through hypercalls(HVC).
The device tree binding for the driver is:
iommu {
compatible = “pkvm,pv-iommu”;
handle=<id>;
};
The device tree binding is typically generated from VMM with a
virtual IOMMU ID that the hypervisor translates to an IOMMU.
Where the id is a unique ID for this IOMMU used when talking with the
hypervisor.
This patch adds IOMMU ops handlers with implementation of trivial
functions only and Kconfig for the driver PKVM_PVIOMMU.
