MPAMCFG_OUT_TL, MPAM Egress PARTID Translation Configuration Register

The MPAMCFG_OUT_TL characteristics are:

Purpose

Enables egress PARTID translation and configures direct egress PARTID translations.

Configuration

The power domain of MPAMCFG_OUT_TL is IMPLEMENTATION DEFINED.

This register is present only when FEAT_MPAM_MSC_DOMAINS is implemented and MPAMF_IDR.HAS_OUT_TL == 1. Otherwise, direct accesses to MPAMCFG_OUT_TL are RES0.

The power and reset domain of each MSC component is specific to that component.

Attributes

MPAMCFG_OUT_TL is a 32-bit register.

ENABLE	RES0															PARTID_TL

ENABLE, bit [31]

Enables egress PARTID translation in the MSC.

ENABLE	Meaning
0b0	Egress PARTID translation is disabled.
0b1	Egress PARTID translation is enabled.

Bits [30:16]

Reserved, RES0.

PARTID_TL, bits [15:0]
When MPAMF_OUT_TL_IDR.HAS_DIRECT_TL == 1:

PARTID to be used as direct translation of the egress PARTID configured in MPAMCFG_PART_SEL.PARTID_SEL when MPAMCFG_PART_SEL.INGRESS_TL == 0.

Otherwise:

Reserved, RES0.

Accessing MPAMCFG_OUT_TL

This register is within the MPAM feature page memory frames.

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_OUT_TL_s must only be accessible from the Secure MPAM feature page.
MPAMCFG_OUT_TL_ns must only be accessible from the Non-secure MPAM feature page.
MPAMCFG_OUT_TL_rt must only be accessible from the Root MPAM feature page.
MPAMCFG_OUT_TL_rl must only be accessible from the Realm MPAM feature page.

MPAMCFG_OUT_TL_s, MPAMCFG_OUT_TL_ns, MPAMCFG_OUT_TL_rt, and MPAMCFG_OUT_TL_rl must be separate registers:

The Secure instance (MPAMCFG_OUT_TL_s) accesses the egress PARTID translation used for Secure PARTIDs.
The Non-secure instance (MPAMCFG_OUT_TL_ns) accesses the egress PARTID translation used for Non-secure PARTIDs.
The Root instance (MPAMCFG_OUT_TL_rt) accesses the egress PARTID translation used for Root PARTIDs.
The Realm instance (MPAMCFG_OUT_TL_rl) accesses the egress PARTID translation used for Realm PARTIDs.

When RIS is implemented, loads and stores to MPAMCFG_OUT_TL access the egress PARTID translation configuration settings without being affected by MPAMCFG_PART_SEL.RIS.

MPAMCFG_OUT_TL can be accessed through the memory-mapped interfaces:

Component	Frame	Offset	Instance
MPAM	MPAMF_BASE_s	0x3208	MPAMCFG_OUT_TL_s

Accesses to this register are RW.
