Processor Configuration Registers
Description
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 reserved.
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.
