Primary Pending Fault (PPF)
This field indicates if there are one or more pending faults logged 

in the fault recording registers. Hardware computes this field as 

the logical OR of Fault (F) fields across all the fault recording 

registers of this remapping hardware unit.
0 = No pending faults in any of the fault recording registers

1 = One or more fault recording registers has pending faults. The 

FRI field is updated by hardware whenever the PPF field is set 

by hardware. Also, depending on the programming of Fault 

Event Control register, a fault event is generated when 

hardware sets this field.

Primary Fault Overflow (PFO)
Hardware sets this field to indicate overflow of fault recording 

registers. Software writing 1 clears this field. When this field is set, 

hardware does not record any new faults until software clears this 

field.
