 === IOMMU ATC capacity allocation and monitoring
 
-The IOMMU may support capacity allocation and usage monitoring in the IOMMU
-address translation cache (IOATC) by implementing a capacity controller register
-interface.

-Some IOMMU may support multiple IOATC where the capacity of each such IOATC may
-not be the same. When multiple IOATC are implemented, (e.g., corresponding to
-each page sizes supported), the IOMMU may implement a capacity controller
-register interface for each IOATC to enable capacity allocation in each IOATC.
