Advanced Fault Log Register (AFLOG_REG_0_0_0_VTDBAR) – Offset 58
Register to specify the base address of the memory-resident fault-log region. This register is treated as RsvdZ for implementations not supporting advanced translation fault logging (AFL field reported as 0 in the Capability register).
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 63:46 | 0h | RO | Reserved |
| 45:12 | 0h | RO | Fault Log Address (FLA) This field specifies the base of 4KB aligned fault-log region in system memory. Hardware ignores and does not implement bits 63:HAW, where HAW is the host address width. |
| 11:9 | 0h | RO | Fault Log Size (FLS) This field specifies the size of the fault log region pointed by the FLA field. The size of the fault log region is 2X * 4KB, where X is the value programmed in this register. |
| 8:0 | 0h | RO | Reserved |
