MSMON_OFLOW_MSI_DATA, MPAM Monitor Overflow MSI Write Data Register

The MSMON_OFLOW_MSI_DATA characteristics are:

Purpose

MSMON_OFLOW_MSI_DATA is a 32-bit read/write register for the MPAM monitor overflow MSI data.

MSMON_OFLOW_MSI_DATA_s is the data for the MSI write for monitor overflow from Secure monitor instances. MSMON_OFLOW_MSI_DATA_ns is the data for the MSI writes for monitor overflow interrupts from Non-secure monitor instances.

Configuration

The power domain of MSMON_OFLOW_MSI_DATA is IMPLEMENTATION DEFINED.

This register is present only when FEAT_MPAMv1p1 is implemented and MPAMF_MSMON_IDR.HAS_OFLW_MSI == 1. Otherwise, direct accesses to MSMON_OFLOW_MSI_DATA are RES0.

MSMON_OFLOW_MSI_ADDR_L, MSMON_OFLOW_MSI_ADDR_H, MSMON_OFLOW_MSI_ATTR, MSMON_OFLOW_MSI_DATA, and MSMON_OFLOW_MSI_MPAM must all be implemented to support MSI writes for monitor overflow interrupts.

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

Attributes

MSMON_OFLOW_MSI_DATA is a 32-bit register.

Accessing MSMON_OFLOW_MSI_DATA

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.

MSMON_OFLOW_MSI_DATA_s must be accessible from the Secure MPAM feature page. MSMON_OFLOW_MSI_DATA_ns must be accessible from the Non-secure MPAM feature page.

MSMON_OFLOW_MSI_DATA_s and MSMON_OFLOW_MSI_DATA_ns must be separate registers. The Secure instance (MSMON_OFLOW_MSI_DATA_s) accesses the monitor overflow MSI write data of Secure monitors, and the Non-secure instance (MSMON_OFLOW_MSI_DATA_ns) accesses the monitor overflow MSI write data of Non-secure monitors.

MSMON_OFLOW_MSI_DATA can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_s0x08E8MSMON_OFLOW_MSI_DATA_s

Accesses on this interface are RW.

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_ns0x08E8MSMON_OFLOW_MSI_DATA_ns

Accesses on this interface are RW.
