MPAMCFG_EN_FLAGS MPAM Partition Configuration Enable Flags Register The power domain of MPAMCFG_EN_FLAGS is IMPLEMENTATION DEFINED when (FEAT_MPAMv0p1 is implemented or FEAT_MPAMv1p1 is implemented) and MPAMF_IDR.HAS_ENDIS == '1' MPAM MPAMF_BASE_s 0x0320 MPAMCFG_EN_FLAGS_s When FEAT_MPAMv1p1 is implemented or FEAT_MPAMv0p1 is implemented RW MPAM MPAMF_BASE_ns 0x0320 MPAMCFG_EN_FLAGS_ns When FEAT_MPAMv1p1 is implemented or FEAT_MPAMv0p1 is implemented RW MPAM MPAMF_BASE_rt 0x0320 MPAMCFG_EN_FLAGS_rt When FEAT_RME is implemented and (FEAT_MPAMv1p1 is implemented or FEAT_MPAMv0p1 is implemented) RW MPAM MPAMF_BASE_rl 0x0320 MPAMCFG_EN_FLAGS_rl When FEAT_RME is implemented and (FEAT_MPAMv1p1 is implemented or FEAT_MPAMv0p1 is implemented) RW Enable flags for 32 PARTIDs. MPAM If FEAT_MPAMv0p1 or FEAT_MPAMv1p1 is implemented, the following statements apply: MPAMCFG_EN_FLAGS_s gives read/write access to 32 Secure PARTIDs. MPAMCFG_EN_FLAGS_ns gives read/write access to 32 Non-secure PARTIDs. If FEAT_RME is implemented, the following statements also apply: MPAMCFG_EN_FLAGS_rl gives read/write access to 32 Realm PARTIDs. MPAMCFG_EN_FLAGS_rt gives read/write access to 32 Root PARTIDs. The power and reset domain of each MSC component is specific to that component. MPAMCFG_EN_FLAGS is a 32-bit register. EN<x> 31 0 31:0 PARTID Enable flags. The group of flags accessed is selected by MPAMCFG_PART_SEL.PARTID_SEL & 0xFFE0 in bit [0] to (MPAMCFG_PART_SEL.PARTID_SEL & 0xFFE0) + 31 in bit [31]. Each bit in MPAMCFG_EN_FLAGS gives access to the same state as controlled by MPAMCFG_EN and MPAMCFG_DIS. Bits MPAMCFG_EN_FLAGS.EN<x>, where (MPAMCFG_PART_SEL.PARTID_SEL & 0xFFE0) + x is greater than MPAMF_IDR.PARTID_MAX, are not required to be implemented. As with other partitioning controls, the enable flag for PARTID 0 must be reset to 1 (enabled). 31 0 0b0 The PARTID is disabled. 0b1 The PARTID is enabled. If both FEAT_MPAM and FEAT_RME are implemented, the following statements apply: In a system that supports Secure, Non-secure, Root, and Realm memory maps, there must be MPAM feature pages in all four address maps: MPAMCFG_EN_FLAGS_s must only be accessible from the Secure MPAM feature page. MPAMCFG_EN_FLAGS_ns must only be accessible from the Non-secure MPAM feature page. MPAMCFG_EN_FLAGS_rt must only be accessible from the Root MPAM feature page. MPAMCFG_EN_FLAGS_rl must only be accessible from the Realm MPAM feature page. MPAMCFG_EN_FLAGS_s, MPAMCFG_EN_FLAGS_ns, MPAMCFG_EN_FLAGS_rt, and MPAMCFG_EN_FLAGS_rl must be separate registers: The Secure instance (MPAMCFG_EN_FLAGS_s) accesses the PARTID enable used for Secure PARTIDs. The Non-secure instance (MPAMCFG_EN_FLAGS_ns) accesses the PARTID enable used for Non-secure PARTIDs. The Root instance (MPAMCFG_EN_FLAGS_rt) accesses the PARTID enable used for Root PARTIDs. The Realm instance (MPAMCFG_EN_FLAGS_rl) accesses the PARTID enable used for Realm PARTIDs. When RIS is implemented, loads and stores to MPAMCFG_EN_FLAGS access the PARTID enable configuration settings for the PARTID enable 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_EN_FLAGS access the PARTID enable configuration settings for the PARTID selected by MPAMCFG_PART_SEL.PARTID_SEL. When PARTID narrowing is implemented, loads and stores to MPAMCFG_EN_FLAGS access the PARTID enable 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_EN_FLAGS access the PARTID enable configuration settings for the request PARTID selected by MPAMCFG_PART_SEL.PARTID_SEL, and MPAMCFG_PART_SEL.INTERNAL must be 0. 2026-03-26 20:27:25 2026-03_rel
