Accessing the MPAMF_PARTID_NRW_IDR

This register is within the MPAM feature page memory frames. In a system that supports Secure and Non-secure memory maps, there must be both Secure and Non-secure MPAM feature pages.

MPAMF_PARTID_NRW_IDR is read-only.

MPAMF_PARTID_NRW_IDR must be readable from the Non-secure and Secure MPAM feature pages.

MPAMF_PARTID_NRW_IDR is permitted to have the same contents when read from either the Secure and Non-secure MPAM feature pages unless the register contents is different for Secure and Non-secure versions, when there must be separate registers in the Secure (MPAMF_PARTID_NRW_IDR_s) and Non-secure (MPAMF_PARTID_NRW_IDR_ns) MPAM feature pages.

MPAMF_PARTID_NRW_IDR can be accessed through the memory-mapped interfaces:
