Thanks Jason, I have verified on aarch64 based on your
jason/smmuv3_nesting branch

https://github.com/Linaro/linux-kernel-uadk/tree/6.12-wip
https://github.com/Linaro/qemu/tree/6.12-wip

Still need this hack
https://github.com/Linaro/linux-kernel-uadk/commit/eaa194d954112cad4da7852e29343e546baf8683

One is adding iommu_dev_enable/disable_feature IOMMU_DEV_FEAT_SVA,
which you have patchset before.
The other is to temporarily ignore S2FWB or CANWBS.

Thanks
