0b

Uncore

Translation Enable Status (TES) 
This field indicates the status of DMA-remapping hardware.
0 = DMA-remapping hardware is not enabled
1 = DMA-remapping hardware is enabled

Root Table Pointer Status (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. 

• set by hardware when hardware completes the 'Set Root 

Table Pointer' operation using the value provided in the Root-

Entry Table Address register.

Uncore

Fault Log Status (FLS) 
This field is:

• cleared by hardware when software Sets the SFL field in the 

Global Command register.

• set by hardware when hardware completes the 'Set Fault Log 

Pointer' operation using the value provided in the Advanced 

Fault Log register.

28

0b

Uncore

Advanced Fault Logging Status (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

RO

0b

Uncore

Write Buffer Flush Status (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

0b

Uncore

Queued Invalidation Enable Status (QIES) 
This field indicates queued invalidation enable status.
0 = Queued invalidation is not enabled
1 = Queued invalidation is enabled 

25

RO-V

0b

Uncore

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 

24

RO-V

0b

Uncore

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. 

• set by hardware when hardware completes the set interrupt 

remap table pointer operation using the value provided in the 

Interrupt Remapping Table Address register.
