MSMON_CFG_MBWU_FLT, MPAM Memory System Monitor Configure Memory Bandwidth Usage Monitor Filter Register

The MSMON_CFG_MBWU_FLT characteristics are:

Purpose

MSMON_CFG_MBWU_FLT is a 32-bit read-write register that sets PARTID and PMG to measure or count in the MBWU monitor selected by MSMON_CFG_MON_SEL. MSMON_CFG_MBWU_FLT_s sets filter conditions for the Secure memory bandwidth usage monitor instance selected by the Secure instance of MSMON_CFG_MON_SEL. MSMON_CFG_MBWU_CTL_ns sets filter conditions for the Non-secure memory bandwidth usage monitor instance selected by the Non-secure instance of MSMON_CFG_MON_SEL.

Configuration

The power domain of MSMON_CFG_MBWU_FLT is IMPLEMENTATION DEFINED.

This register is present only when MPAMF_IDR.HAS_MSMON == 1 and MPAMF_MSMON_IDR.MSMON_MBWU == 1. Otherwise, direct accesses to MSMON_CFG_MBWU_FLT are RES0.

Attributes

MSMON_CFG_MBWU_FLT is a 32-bit register.

Field descriptions

The MSMON_CFG_MBWU_FLT bit assignments are:

313029282726252423222120191817161514131211109876543210
RES0PMGPARTID

Bits [31:24]

Reserved, RES0.

PMG, bits [23:16]

Performance monitoring group to filter memory bandwidth usage monitoring.

If MSMON_CFG_MBWU_CTL.MATCH_PMG == 0, this field is not used to match memory bandwidth to a PMG and the contents of this field is ignored.

If MSMON_CFG_MBWU_CTL.MATCH_PMG == 1, the monitor selected by MSMON_CFG_MON_SEL measures or counts memory bandwidth labeled with PMG equal to this field.

PARTID, bits [15:0]

Partition ID to filter memory bandwidth usage monitoring.

If MSMON_CFG_MBWU_CTL.MATCH_PARTID == 0, this field is not used to match memory bandwidth to a PARTID and the contents of this field is ignored.

If MSMON_CFG_MBWU_CTL.MATCH_PARTID == 1, the monitor selected by MSMON_CFG_MON_SEL measures or counts memory bandwidth labeled with PARTID equal to this field.

Accessing the MSMON_CFG_MBWU_FLT

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_CFG_MBWU_FLT_s must be accessible from the Secure MPAM feature page. MSMON_CFG_MBWU_FLT_ns must be accessible from the Non-secure MPAM feature page.

MSMON_CFG_MBWU_FLT_s and MSMON_CFG_MBWU_FLT_ns must be separate registers. The Secure instance (MSMON_CFG_MBWU_FLT_s) accesses the PARTID and PMG matching for a memory bandwidth usage monitor used for Secure PARTIDs, and the Non-secure instance (MSMON_CFG_MBWU_FLT_ns) accesses the PARTID and PMG matching for a memory bandwidth usage monitor used for Non-secure PARTIDs.

MSMON_CFG_MBWU_FLT can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_s0x0820MSMON_CFG_MBWU_FLT_s

Accesses on this interface are RW.

ComponentFrameOffsetInstance
MPAMMPAMF_BASE_ns0x0820MSMON_CFG_MBWU_FLT_ns

Accesses on this interface are RW.
