This word is used to describe a XIO endpoint. A widget contains several registers, including the 32-bit widget ID register at 0x04. The ID register can be further decoded into a manufacturer-device-revision triplet:
- 0xF0000000 - revision
- 0x0FFFF000 - device
- 0x00000FFE - manufacturer
The LSB is usually set to 1.
Known XIO widget IDs (manufacturer/device) include:
- 000/0000 - XBow
- 000/D000 - XXBow (a XBow inside an XBridge, used in Origin 3000 series)
- 024/C202 - TPU (Tensor Processing Unit)
- 024/D002 - XBridge
- 036/C001 - HEART (IP30 host bridge)
- 036/C002 - BRIDGE (PCI bridge)
- 036/C101 - HUB (IP27 host bridge)
- 036/C110 - Bedrock (IP35 host bridge)
- 2AA/C003 - HQ4 (IMPACTSR command processor)
- 2AA/C102 - XG (KONA frontend)
