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 exsiting IOMMU SVA implementation by assigning an SVA type of iommu domain to a shared virtual address and replacing sva_bind/unbind iommu ops with a set_dev_pasid domain 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 on an x86 machine and compile tested for all architectures. This series is also available on github: [2] https://github.com/LuBaolu/intel-iommu/commits/iommu-sva-refactoring-v11 Please review and suggest.
Tested-by: Zhangfei Gao <zhangfei.gao@xxxxxxxxxx> On arm64 (Kunpeng920) with uacce. Thanks
