The MPAMCFG_DIS characteristics are:
Disables a PARTID configuration as set in other MPAMCFG registers.
MPAMCFG_DIS_s disables a Secure PARTID. MPAMCFG_DIS_ns disables a Non-secure PARTID.
The power domain of MPAMCFG_DIS is IMPLEMENTATION DEFINED.
This register is present only when (FEAT_MPAMv0p1 is implemented or FEAT_MPAMv1p1 is implemented) and MPAMF_IDR.HAS_ENDIS == 1. Otherwise, direct accesses to MPAMCFG_DIS are RES0.
MPAMCFG_DIS is a 32-bit register.

NFU | RES0 | PARTID |
No Future Use.
NFU | Meaning |
---|---|
0b0 | Control settings of the disabled PARTID must be retained. |
0b1 | Control settings of the disabled PARTID may take an UNKNOWN value. |
Reserved, RES0.
Selects the PARTID to disable.
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.
MPAMCFG_DIS_s must be accessible from the Secure MPAM feature page. MPAMCFG_DIS_ns must be accessible from the Non-secure MPAM feature page.
MPAMCFG_DIS_s and MPAMCFG_DIS_ns must be separate registers. The Secure instance (MPAMCFG_DIS_s) accesses the PARTID disable used for Secure PARTIDs, and the Non-secure instance (MPAMCFG_DIS_ns) accesses the PARTID disable used for Non-secure PARTIDs.
When RIS is implemented, loads and stores to MPAMCFG_DIS access the PARTID disable configuration settings for the PARTID disable resource instance selected by MPAMCFG_PART_SEL.RIS and the PARTID selected by MPAMCFG_PART_SEL.PARTID_SEL.
When RIS is not implemented, loads and stores to MPAMCFG_DIS access the PARTID disable configuration settings for the PARTID selected by MPAMCFG_PART_SEL.PARTID_SEL.
When PARTID narrowing is implemented, loads and stores to MPAMCFG_DIS access the PARTID disable configuration settings for the internal PARTID selected by MPAMCFG_PART_SEL.PARTID_SEL, and MPAMCFG_PART_SEL.INTERNAL must be 1.
When PARTID narrowing is not implemented, loads and stores to MPAMCFG_DIS access the PARTID disable configuration settings for the request PARTID selected by MPAMCFG_PART_SEL.PARTID_SEL, and MPAMCFG_PART_SEL.INTERNAL must be 0.
