MPAMF_IMPL_IDR, MPAM Implementation-Specific Partitioning Feature Identification Register

The MPAMF_IMPL_IDR characteristics are:

Purpose

The MPAMF_IMPL_IDR is a 32-bit read-only register that indicates the implementation-defined partitioning and monitoring features and parameters of the MSC. MPAMF_IMPL_IDR_s indicates implementation-defined partitioning and monitoring features accessed from the Secure MPAM feature page. MPAMF_IMPL_IDR_ns indicates those accessed from the Non-secure MPAM feature page.

Configuration

The power domain of MPAMF_IMPL_IDR is IMPLEMENTATION DEFINED.

This register is present only when MPAMF_IDR.HAS_IMPL_IDR == 1. Otherwise, direct accesses to MPAMF_IMPL_IDR are RES0.

Attributes

MPAMF_IMPL_IDR is a 32-bit register.

Field descriptions

The MPAMF_IMPL_IDR bit assignments are:

313029282726252423222120191817161514131211109876543210
IMP DEF

IMP DEF, bits [31:0]

IMPLEMENTATION DEFINED.

All 32 bits of this register are available to be used as the implementer sees fit to indicate the presence of implementation-defined MPAM features in this MSC and to give additional implementation-specific read-only information about the parameters of implementation-specific MPAM features to software.

Accessing the MPAMF_IMPL_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_IMPL_IDR is read-only.

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

MPAMF_IMPL_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_IMPL_IDR_s) and Non-secure (MPAMF_IMPL_IDR_ns) MPAM feature pages.

MPAMF_IMPL_IDR can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_s0x0028MPAMF_IMPL_IDR_s

Accesses on this interface are RO.

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_ns0x0028MPAMF_IMPL_IDR_ns

Accesses on this interface are RO.
