MSMON_CFG_CSU_FLT, MPAM Memory System Monitor Configure Cache Storage Usage Monitor Filter Register

The MSMON_CFG_CSU_FLT characteristics are:

Purpose

Configures PARTID and PMG to measure or count in the CSU monitor selected by MSMON_CFG_MON_SEL. MSMON_CFG_CSU_FLT_s sets filter conditions for the Secure cache storage usage monitor instance selected by the Secure instance of MSMON_CFG_MON_SEL. MSMON_CFG_CSU_CTL_ns sets filter conditions for the Non-secure cache storage usage monitor instance selected by the Non-secure instance of MSMON_CFG_MON_SEL.

If MPAMF_IDR.HAS_RIS is 1, the monitor instance filter configuration accessed is for the resource instance currently selected by MSMON_CFG_MON_SEL.RIS and the monitor instance of that resource instance selected by MSMON_CFG_MON_SEL.MON_SEL.

Configuration

The power domain of MSMON_CFG_CSU_FLT is IMPLEMENTATION DEFINED.

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

Attributes

MSMON_CFG_CSU_FLT is a 32-bit register.

Field descriptions

The MSMON_CFG_CSU_FLT bit assignments are:

Bits [31:24]

Reserved, RES0.

PMG, bits [23:16]

Performance monitoring group to filter cache storage usage monitoring.

If MSMON_CFG_CSU_CTL.MATCH_PMG == 0, this field is not used to match cache storage to a PMG and the contents of this field is ignored.

If MSMON_CFG_CSU_CTL.MATCH_PMG == 1 and MSMON_CFG_CSU_CTL.MATCH_PARTID == 1, the monitor instance selected by MSMON_CFG_MON_SEL measures or counts cache storage labeled with PMG equal to this field and PARTID equal to the PARTID field.

If MSMON_CFG_CSU_CTL.MATCH_PMG == 1 and MSMON_CFG_CSU_CTL.MATCH_PARTID == 0, the behavior of the monitor instance selected by MSMON_CFG_MON_SEL is CONSTRAINED UNPREDICTABLE. See MSMON_CFG_CSU_CTL.MATCH_PMG for more information.

PARTID, bits [15:0]

Partition ID to filter cache storage usage monitoring.

If MSMON_CFG_CSU_CTL.MATCH_PARTID == 0 and MSMON_CFG_CSU_CTL.MATCH_PMG == 0, the monitor measures all allocated cache storage.

If MSMON_CFG_CSU_CTL.MATCH_PARTID == 0 and MSMON_CFG_CSU_CTL.MATCH_PMG == 1, the behavior of the monitor is CONSTRAINED UNPREDICTABLE. See the description of MSMON_CFG_CSU_CTL.MATCH_PMG.

If MSMON_CFG_CSU_CTL.MATCH_PARTID == 1 and MSMON_CFG_CSU_CTL.MATCH_PMG == 0, the monitor selected by MSMON_CFG_MON_SEL measures or counts cache storage labeled with PARTID equal to this field.

If MSMON_CFG_CSU_CTL.MATCH_PARTID == 1 and MSMON_CFG_CSU_CTL.MATCH_PMG == 1, the monitor selected by MSMON_CFG_MON_SEL measures or counts cache storage labeled with PARTID equal to this field and PMG equal to the PMG field.

Accessing the MSMON_CFG_CSU_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_CSU_FLT_s must be accessible from the Secure MPAM feature page. MSMON_CFG_CSU_FLT_ns must be accessible from the Non-secure MPAM feature page.

MSMON_CFG_CSU_FLT_s and MSMON_CFG_CSU_FLT_ns must be separate registers. The Secure instance (MSMON_CFG_CSU_FLT_s) accesses the PARTID and PMG matching for a cache storage usage monitor used for Secure PARTIDs, and the Non-secure instance (MSMON_CFG_CSU_FLT_ns) accesses the PARTID and PMG matching for a cache storage usage monitor used for Non-secure PARTIDs.

When RIS is implemented, loads and stores to MSMON_CFG_CSU_FLT access the monitor configuration settings for the resource instance selected by MSMON_CFG_MON_SEL.RIS and the cache storage usage monitor instance selected by MSMON_CFG_MON_SEL.MON_SEL.

When RIS is not implemented, loads and stores to MSMON_CFG_CSU_FLT access the monitor configuration settings for the cache storage usage monitor instance selected by MSMON_CFG_MON_SEL.MON_SEL.

MSMON_CFG_CSU_FLT can be accessed through the memory-mapped interfaces:
