Intel® Core™ Ultra Processors for H-series and U-series Platforms SOC I/O Registers
Subsystem ID And Subsystem Vendor ID (KT_HOST_SID_SVID) – Offset 2c
These registers are used to uniquely identify the add-in card or subsystem where the PCI
\t\tdevice resides. They provide a mechanism for add-in card vendors to distinguish their add-in
\t\tcards from one another even though the add-in cards may have the same PCI controller
\t\ton them (and, therefore, the same Vendor ID and Device ID).
