Title: METHOD AND APPARATUS FOR MANAGING RESOURCE ACCESS CONTROL HARDWARE IN A SYSTEM-ON-CHIP DEVICE
Abstract:
In an aspect, an apparatus obtains, at one or more hardware configuration interfaces, a physical page number associated with a secure resource, a domain identifier, and at least one memory attribute. The one or more hardware configuration interfaces may be in communication with a resource protection unit that manages access to the secure resource. The apparatus configures, by the one or more hardware configuration interfaces, a page table entry in a page table maintained at the resource protection unit, where the page table entry is configured to include the physical page number associated with the secure resource, the domain identifier, and the at least one memory attribute. The resource protection unit processes a resource access transaction when an access permission for the resource access transaction is determined in the page table.
