Uncore

Advanced Fault Overflow (AFO) 
Hardware sets this field to indicate advanced fault log overflow 

condition. At this time, a fault event is generated based on the 

programming of the Fault Event Control register.
Software writing 1 to this field clears it.
Hardware implementations not supporting advanced fault 

logging implement this bit as RsvdZ.

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.
