Fault Log Status (FLS): This field is valid only for
implementations supporting advanced fault logging.
This field indicates the status of the fault-log pointer in
hardware.
This field is cleared by hardware when software sets the
SFL field in the Global Command register. This field is set
by hardware when hardware completes the set fault-log
pointer operation using the value provided in the Advanced
Fault Log register.
Advanced Fault Logging Status (AFLS): This field is
valid only for implementations supporting advanced fault
logging.
This field indicates advanced fault logging status.
0 = Advanced Fault Logging is not enabled
1 = Advanced Fault Logging is enabled
Write Buffer Flush Status (WBFS): This bit is valid only
for implementations requiring write buffer flushing.
This field indicates the status of the write buffer flush
operation. This field is set by hardware when software sets
the WBF field in the Global Command register. This field is
cleared by hardware when hardware completes the write
buffer flushing operation.
Queued Invalidation Enable Status (QIES): This field
indicates queued invalidation enable status.
0 = queued invalidation is not enabled
1 = queued invalidation is enabled
Interrupt Remapping Enable Status (IRES): This field
indicates the status of Interrupt-remapping hardware.
0 = Interrupt-remapping hardware is not enabled
1 = Interrupt-remapping hardware is enabled
Interrupt Remapping Table Pointer Status (IRTPS):
This field indicates the status of the interrupt remapping
table pointer in hardware.
This field is cleared by hardware when software sets the
SIRTP field in the Global Command register. This field is
Set by hardware when hardware completes the set
interrupt remap table pointer operation using the value
provided in the Interrupt Remapping Table Address
register.
Compatibility Format Interrupt Status (CFIS): This
field indicates the status of Compatibility format interrupts
on Intel®64 implementations supporting interrupt-
remapping. The value reported in this field is applicable
only when interrupt-remapping is enabled and Legacy
interrupt mode is active.
0 = Compatibility format interrupts are blocked.
1 = Compatibility format interrupts are processed as pass-
through (bypassing interrupt remapping).
