Bits [31:8]

Reserved, RES0.

ArchMajorRev, bits [7:4]

Major revision of the MPAM architecture implemented by the MSC.

ArchMinorRev, bits [3:0]

Minor revision of the MPAM architecture implemented by the MSC.

Accessing the MPAMF_AIDR

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_AIDR is read-only.

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

MPAMF_AIDR must have the same contents in the Secure and Non-secure MPAM feature pages.

MPAMF_AIDR can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_s0x0020MPAMF_AIDR

Accesses on this interface are RO.

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_ns0x0020MPAMF_AIDR

Accesses on this interface are RO.
