The MSMON_CFG_MBWU_FLT characteristics are:
Controls 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.
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.
The power domain of MSMON_CFG_MBWU_FLT is IMPLEMENTATION DEFINED.
This register is present only when FEAT_MPAM is implemented, MPAMF_IDR.HAS_MSMON == 1 and MPAMF_MSMON_IDR.MSMON_MBWU == 1. Otherwise, direct accesses to MSMON_CFG_MBWU_FLT are RES0.
MSMON_CFG_MBWU_FLT is a 32-bit register.
The MSMON_CFG_MBWU_FLT bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
RWBW | RES0 | PMG | PARTID |
RW filtering.
Read/write bandwidth filter. Configures the selected monitor instance to count all bandwidth, only read bandwidth or only write bandwidth.
RWBW | Meaning |
---|---|
0b00 | Monitor instance counts read bandwidth and write bandwidth. |
0b01 | Monitor instance counts write bandwidth only. |
0b10 | Monitor instance counts read bandwidth only. |
0b11 | Reserved. |
Reserved, RES0.
Reserved, RES0.
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.
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.

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.
When RIS is implemented, loads and stores to MSMON_CFG_MBWU_FLT access the monitor configuration settings for the bandwidth resource instance selected by MSMON_CFG_MON_SEL.RIS and the memory bandwidth usage monitor instance selected by MSMON_CFG_MON_SEL.MON_SEL.
When RIS is not implemented, loads and stores to MSMON_CFG_MBWU_FLT access the monitor configuration settings for the memory bandwidth usage monitor instance selected by MSMON_CFG_MON_SEL.MON_SEL.
