Processor Uncore Configuration Registers
4.4 PCI Standard Registers
These registers appear in every function for every device.
4.4.1 VID—Vendor Identification Register
The VID Register contains the vendor identification number. This 16-bit register,
combined with the Device Identification Register uniquely identifies the manufacturer
of the function within the processor. Writes to this register have no effect.
4.4.2 DID—Device Identification Register
This 16-bit register combined with the Vendor Identification register uniquely identifies
the Function within the processor. Writes to this register have no effect. See Table 4-1
for the DID of each processor function.
