Register to provide the DMA address whose corresponding IOTLB entry needs to be
invalidated through the corresponding IOTLB Invalidate register. This register is a
write-only register.
Access Method
Default: 0h
59:40
0h
RO
PN: PASID value in the faulted request. This field is relevant only when the PP field is
set. Hardware implementations not supporting PASID (PASID field Clear in Extended
Capability register) implement this field as RsvdZ.
39:32
0h
ROSV
FR: Reason for the fault.
This field is relevant only when the F field is set.
31
0h
RO
PP: When set, indicates the faulted request has a PASID tag. The value of the PASID
field is reported in the PASID Value (PV) field. This field is relevant only when the F
field is Set, and when the fault reason (FR) indicates one of the non-recoverable
address translation fault conditions. Hardware implementations not supporting PASID
(PASID field Clear in Extended Capability register) implement this field as RsvdZ.
30
0h
RO
EXE: When set, indicates Execute permission was requested by the faulted read
request. This field is relevant only when the PP field and T field are both Set. Hardware
implementations not supporting PASID (PASID field Clear in Extended Capability
register) implement this field as RsvdZ.
29
0h
RO
PRIV: When set, indicates Supervisor privilege was requested by the faulted request.
This field is relevant only when the PP field is Set. Hardware implementations not
supporting PASID (PASID field Clear in Extended Capability register) implement this
field as RsvdZ.
