MPAMF_ERR_MSI_MPAM, MPAM Error MSI Write MPAM Information Register

The MPAMF_ERR_MSI_MPAM characteristics are:

Purpose

MPAMF_ERR_MSI_MPAM is a 32-bit read/write register that sets the MPAM information for error MSI write attributes for MPAM errors in this MSC.

MPAMF_ERR_MSI_MPAM_s controls MPAM information labeling of Secure MPAM error MSI writes. MPAMF_ERR_MSI_MPAM_ns controls MPAM information labeling of Non-secure MPAM error MSI writes.

Configuration

The power domain of MPAMF_ERR_MSI_MPAM is IMPLEMENTATION DEFINED.

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

The power and reset domain of each MSC component is specific to that component.

Attributes

MPAMF_ERR_MSI_MPAM is a 32-bit register.

Field descriptions

313029282726252423222120191817161514131211109876543210
RES0PMGPARTID

Bits [31:24]

Reserved, RES0.

PMG, bits [23:16]

Performance monitoring group property for PARTID MSC error interrupt write.

The reset behavior of this field is:

PARTID, bits [15:0]

Partition ID for MSC error interrupt write.

The PARTID in this register is in the Secure PARTID space in the MPAMF_ERR_MSI_MPAM_s instance and in the Non-secure PARTID space in the MPAMF_ERR_MSI_MPAM_ns instance of this register.

The reset behavior of this field is:

Accessing MPAMF_ERR_MSI_MPAM

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_ERR_MSI_MPAM_s must be accessible from the Secure MPAM feature page. MPAMF_ERR_MSI_MPAM_ns must be accessible from the Non-secure MPAM feature page.

MPAMF_ERR_MSI_MPAM_s and MPAMF_ERR_MSI_MPAM_ns must be separate registers. The Secure instance (MPAMF_ERR_MSI_MPAM_s) accesses the MPAM information for MSI write request to signal an MPAM error used for Secure PARTIDs, and the Non-secure instance (MPAMF_ERR_MSI_MPAM_ns) accesses the MPAM information for MSI write request to signal an MPAM error used for Non-secure PARTIDs.

MPAMF_ERR_MSI_MPAM can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_s0x00DCMPAMF_ERR_MSI_MPAM_s

Accesses on this interface are RW.

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_ns0x00DCMPAMF_ERR_MSI_MPAM_ns

Accesses on this interface are RW.
