Description
Advanced Fault Overflow (AFO)
Hardware sets this bit 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 bit indicates if there are one or more pending faults logged in
the fault recording registers. Hardware computes this bit 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 when the PPF bit 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 bit to indicate overflow of fault recording
registers. Software writing 1 clears this bit. When this bit is set,
hardware does not record any new faults until software clears this
bit.
