RTPIDR_EL0, Restricted Read/Write Software Thread ID Register

The RTPIDR_EL0 characteristics are:

Purpose

Provides a location where software can store thread identifying information, for OS management purposes.

The PE makes no use of this register.

Configuration

This register is present only when Morello is implemented. Otherwise, direct accesses to RTPIDR_EL0 are UNDEFINED.

RW fields in this register reset to architecturally UNKNOWN values.

Attributes

RTPIDR_EL0 is a 129-bit register.

Field descriptions

The RTPIDR_EL0 bit assignments are:

Bits [128:0]

Restricted Thread ID. The version of the Thread ID when the PE is in Restricted.

This field resets to an architecturally UNKNOWN value.

Accessing the RTPIDR_EL0

Access to RTPIDR_EL0 via MSR aand MRS instructions is only possible when the PE is in Executive.

When the PE is in Restricted, operations which use TPIDR_ELx or CTPIDR_ELx access RTPIDR_EL0.

Accesses to this register use the following encodings:
