  • TECHNOLOGY FOR TRANSFERRING IOMMU OWNERSHIP TO A NEW VERSION OF SYSTEM SOFTWARE
    Publication number: 20220100532
    Abstract: A processor package comprises a processing core, a system agent, an input/output memory management unit (IOMMU), and transaction security circuitry (TSC) in at least one of the system agent and the IOMMU. The TSC determines whether ultra-protected memory (UPM) is enabled in a data processing system that comprises the processor package. The transaction security circuitry also determines whether an address for a memory access transaction in the data processing system falls within a UPM region within a physical address space of the data processing system. The transaction security circuitry also blocks the memory access transaction, in response to a determination that (a) UPM is enabled and (b) the address for the memory access transaction falls within the UPM region. Other embodiments are described and claimed.
