[PATCH 00/10] Let IOMMU core know about individual IOMMUs

[Joerg Roedel]

Hi,

the IOMMU core code already has two ways of representing
individual hardware IOMMUs. One is the sysfs code and the
other is the newer iommu_register_instance interface. These
two interfaces are special purpose and can be unified.

This unification is attempted in this patch-set. It
introduces an extensible 'struct iommu_device' which
represents a hardware IOMMU in the IOMMU core code.

For now the struct contains a pointer to the iommu_ops, which
is a step to get rid of the per-bus iommu_ops, and a pointer
to a firmware-node structure.

The patches have been tested on x86 hardware and an AMD Seattle
ARM64 system.

Please review, test and provide feedback!

Thanks a lot,

       Joerg
