ERRDEVID, Device Configuration Register

The ERRDEVID characteristics are:

Purpose

Provides discovery information for the component.

Configuration

ERRDEVID is implemented only as part of a memory-mapped group of error records.

Attributes

ERRDEVID is a 32-bit register.

RES0PFGRES0IRQCRNUM

Bits [31:22]

Reserved, RES0.

PFG, bit [21]
When RAS System Architecture v2 is implemented:

Common Fault Injection Mechanism. Describes whether any Common Fault Injection Mechanism registers are implemented in the same page as this register.

The value of this field is an IMPLEMENTATION DEFINED choice of:

PFGMeaning
0b0

Any Common Fault Injection Mechanism registers are implemented in the same page as this register.

0b1

Any Common Fault Injection Mechanism registers are implemented in a separate fault injection group page.

Note

The value of this field does not indicate that any Common Fault Injection Mechanism registers are implemented by the nodes in this error record group. Software must use ERR<n>FR to discover whether each node implements Common Fault Injection Mechanism registers.

Accessing this field has the following behavior:


Otherwise:

Reserved, RAZ.

Bit [20]

Reserved, RES0.

IRQCR, bits [19:16]

Interrupt Control registers. Describes whether the interrupt control registers are implemented.

The value of this field is an IMPLEMENTATION DEFINED choice of:

IRQCRMeaning
0b0000

It is IMPLEMENTATION DEFINED whether any interrupt control registers are implemented.

0b0001

An IMPLEMENTATION DEFINED form of interrupt control registers are implemented.

0b0010

The recommended layout form of interrupt control registers are implemented, for simple interrupts.

0b0011

The recommended layout form of interrupt control registers are implemented, for message-signaled interrupts.

0b1111

Interrupt control registers are not implemented.

All other values are reserved.

Accessing this field has the following behavior:

NUM, bits [15:0]

Highest numbered index of the error records in this group, plus one. Each implemented record is owned by a node. A node might own multiple records.

This manual describes a group of error records accessed via a standard 4KB memory-mapped peripheral. For a 4KB peripheral, up to 24 error records can be accessed if the Common Fault Injection Model is implemented, and up to 56 otherwise.

This field has an IMPLEMENTATION DEFINED value.

Access to this field is RO.

Accessing ERRDEVID

ERRDEVID can be accessed through the memory-mapped interfaces:

ComponentOffsetInstance
RAS0xFC8ERRDEVID

Accesses on this interface are RO.
