FRCD_REG - Fault Recording Registers
B/D/F/Type:
Address Offset:
Default Value:
Access:
Size:
Registers to record fault information when primary fault logging is active. Hardware
reports the number and location of fault recording registers through the Capability
register. This register is relevant only for primary fault logging.
These registers are sticky and can be cleared only through power good reset or by
software clearing the RW1C fields by writing a 1.

Domain-ID (DID)
Indicates the ID of the domain whose IOTLB entries need to
be selectively invalidated. This field must be programmed
by software for domain-selective and page-selective
invalidation requests.
The Capability register reports the domain-id width
supported by hardware. Software must ensure that the
value written to this field is within this limit. Hardware
ignores and not implement Bits 47:(32+N), where N is the
supported domain-id width reported in the Capability
register.
Reserved
Fault (F)
Hardware sets this field to indicate a fault is logged in this
Fault Recording register. The F field is Set by hardware after
the details of the fault is recorded in other fields.
When this field is Set, hardware may collapse additional
faults from the same source-id (SID).
Software writes the value read from this field to Clear it.
Type (T)
Type of the faulted request:
0 = Write request
1 = Read request
This field is relevant only when the F field is Set, and when
the fault reason (FR) indicates one of the DMA-remapping
fault conditions.
