MSMON_CAPT_EVNT, MPAM Capture Event Generation Register

The MSMON_CAPT_EVNT characteristics are:

Purpose

Generates a local capture event when written with bit[0] as 1. MSMON_CAPT_EVNT_s generates local capture events for Secure monitors only or for Secure and Non-secure monitors. MSMON_CAPT_EVNT_ns generates local capture events for Non-secure monitors only.

Configuration

The power domain of MSMON_CAPT_EVNT is IMPLEMENTATION DEFINED.

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

Attributes

MSMON_CAPT_EVNT is a 32-bit register.

Field descriptions

The MSMON_CAPT_EVNT bit assignments are:

Bits [31:2]

Reserved, RES0.

ALL, bit [1]

In the Secure instance of this register, if ALL written as 1 and NOW is also written as 1, signal a capture event to Secure and Non-secure monitor instances in this MSC that are configured with CAPT_EVNT = 7.

If written as 0 and NOW is written as 1, signal a capture event to Secure monitor instances in this MSC that are configured with CAPT_EVNT = 7.

In the Non-secure instance of this register, this bit is RAZ/WI.

This bit always reads as zero.

NOW, bit [0]

When written as 1, this bit causes an event to all monitors in this MSC with CAPT_EVNT set to the value of 7.

When this bit is written as 0, no event is signaled.

This bit always reads as zero.

Accessing the MSMON_CAPT_EVNT

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_CAPT_EVNT_s must be accessible from the Secure MPAM feature page. MSMON_CAPT_EVENT_ns must be accessible from the Non-secure MPAM feature page.

The two instances of MSMON_CAPT_EVNT must be separate registers. The Secure instance (MSMON_CAPT_EVNT_s) can generate capture events for both Secure and Non-secure PARTID monitors, and the Non-secure instance (MSMON_CAPT_EVNT_ns) can generate capture events for Non-secure PARTID monitors only.

MSMON_CAPT_EVNT can be accessed through the memory-mapped interfaces:

Accesses on this interface are RW.
