Global Status Register (GSTS_REG_0_0_0_VTDBAR) – Offset 2001c
Register to report general remapping hardware status.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31 | 0h | RO/V | Translation Enable Status (TES) This field indicates the status of DMA-remapping hardware.
|
| 30 | 0h | RO/V | 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. 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. |
| 29 | 0h | RO | Fault Log Status (FLS) This field:
|
| 28 | 0h | RO | Adavanced Fault Logging Status (AFLS) This field is valid only for implementations supporting advanced fault logging. It indicates the advanced fault logging status:
|
| 27 | 0h | RO | 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:
|
| 26 | 0h | RO/V | Queued Invalidation Enable Status (QIES) This field indicates queued invalidation enable status.
|
| 25 | 0h | RO/V | Interrupt Remapping Enable Status (IRES) This field indicates the status of Interrupt-remapping hardware.
|
| 24 | 0h | RO/V | Interrupt Remapping 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. |
| 23 | 0h | RO/V | Compatibility Format Interrupt Status (CFIS) This field indicates the status of Compatibility format interrupts on Intel64 implementations supporting interrupt-remapping. The value reported in this field is applicable only when interrupt-remapping is enabled and Extended Interrupt Mode (x2APIC mode) is not enabled.
