IOMMU Domain Authority Control [i] Register

Software can set 15 different permission control types in IOMMU_DM_AUT_CTRL0-7. A default access control type is DOMAIN0. The read/write operation of DOMAIN1-15 is unlimited by default.

Software needs to set the index of the permission control domain corresponding to the page table item in the bit[7:4] of the Level2 page table, the default value is 0 (use domain 0), that is, the read/write operation is not controlled.

Setting REG_ARD_OVWT can mask the Domain control defined by IOMMU_DM_AUT_CTRL0-7. All Level2 page table type are covered by the type of REG_ARD_OVWT. The read/write operation is permitted by default.
