Processor Configuration Registers
1RO-V-S 0b
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 the 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.
