ROV
TES: This field indicates the status of DMA-remapping hardware.
0: DMA-remapping hardware is not enabled
1: DMA-remapping hardware is enabled

0h
RO_V
RTPS: This field indicates the status of the root- table pointer in hardware.
This field is cleared by hardware when software sets the SRTP field in the Global
Command register. This field is set by hardware when hardware completes the 'Set
Root Table Pointer' operation using the value provided in the Root-Entry Table Address
register.

0h
RO
FLS: This field:
- Is cleared by hardware when software Sets the SFL field in the Global Command
register.
- Is Set by hardware when hardware completes the 'Set Fault Log Pointer' operation
using the value provided in the Advanced Fault Log register.
28
0h
RO
AFLS: This field is valid only for implementations supporting advanced fault logging. It
indicates the advanced fault logging status:
0: Advanced Fault Logging is not enabled.
1: Advanced Fault Logging is enabled.
27
0h
RO
WBFS: This field is valid only for implementations requiring write buffer flushing. This
field indicates the status of the write buffer flush command. It is:
- Set by hardware when software sets the WBF field in the Global Command register.
- Cleared by hardware when hardware completes the write buffer flushing operation.
26

RO_V
QIES: This field indicates queued invalidation enable status.
0: queued invalidation is not enabled
1: queued invalidation is enabled
25
0h
ROV
IRES: This field indicates the status of Interrupt-remapping hardware.
0: Interrupt-remapping hardware is not enabled
1: Interrupt-remapping hardware is enabled
