Hi folks,

The former part of this series introduces the IOMMU interfaces to attach
or detach an iommu domain to/from a pasid of a device, and refactors the
existing IOMMU SVA implementation by assigning an SVA type of iommu
domain to a shared virtual address and replacing sva_bind/unbind iommu
ops with set/remove_dev_pasid ops.

The latter part changes the existing I/O page fault handling framework
from only serving SVA to a generic one. Any driver or component could
handle the I/O page faults for its domain in its own way by installing
an I/O page fault handler.

This series has been functionally tested by Tony Zhu on Intel hardware
and Zhangfei Gao on arm64 (Kunpeng920) hardware. Thanks a lot for the
efforts.

This series is also available on github:

Please review and suggest.

Hi Joerg,

Can you please help to look at this series. Is there anything to be
improved? Whose else "reviewed-by" would you like to see?

Best regards,
