1: Hardware is prohibited from issuing interrupt message requests.
0: Software has cleared this bit to indicate interrupt service is available.
0: Software has cleared this bit to indicate interrupt service is available.
When a faulting condition is detected, hardware may issue a interrupt
request (using the fault event data and fault event address register values)
depending on the state of the interrupt mask and interrupt pending bits.

fault_nonisoch_msi_pend:
Hardware sets the IP field whenever it detects an interrupt condition.
Interrupt condition is defined as when an interrupt condition occurs when
hardware records a fault through one of the Fault Recording registers and
sets the PPF field in Fault Status register. - Hardware detected error
associated with the Invalidation Queue, setting the IQE field in the Fault
Status register.
- Hardware detected invalidation completion timeout error, setting the ICT
- Hardware detected invalidation completion timeout error, setting the ICT
field in the Fault Status register.
- If any of the above status fields in the Fault Status register was already set
- If any of the above status fields in the Fault Status register was already set
at the time of setting any of these fields, it is not treated as a new interrupt
condition.
The IP field is kept set by hardware while the interrupt message is held
The IP field is kept set by hardware while the interrupt message is held
pending. The interrupt message could be held pending due to interrupt mask
(IM field) being set, or due to other transient hardware conditions.
The IP field is cleared by hardware as soon as the interrupt message pending
The IP field is cleared by hardware as soon as the interrupt message pending
condition is serviced. This could be due to either
(a) Hardware issuing the interrupt message due to either change in the
(a) Hardware issuing the interrupt message due to either change in the
transient hardware condition that caused interrupt message to be held
pending or due to software clearing the IM field.
(b) Software servicing all the pending interrupt status fields in the Fault
(b) Software servicing all the pending interrupt status fields in the Fault
Status register.
- PPF field is cleared by hardware when it detects all the Fault Recording
- PPF field is cleared by hardware when it detects all the Fault Recording
registers have Fault (F) field clear.
- Other status fields in the Fault Status register is cleared by software
- Other status fields in the Fault Status register is cleared by software
writing back the value read from the respective fields.
