Device Identification Number (DID3)
Identifier assigned to the MCH Device 3 (virtual PCI-to-PCI bridge, PCI Express port).
Port Number
Indicates the PCI Express port number for the given PCI Express link. Matches the
value in Element Self Description [31:24].
Reserved
L1 Exit Latency
Indicates the length of time this Port requires to complete the transition from L1 to
L0. The value 010 b indicates the range of 2 µs to less than 4 µs. If this field is
required to be any value other than the default, BIOS must initialize it accordingly.
Both bytes of this register that contain a portion of this field must be written
simultaneously in order to prevent an intermediate (and undesired) value from ever
existing.
L0s Exit Latency
Indicates the length of time this Port requires to complete the transition from L0s to
L0. The value 010 b indicates the range of 128 ns to less than 256 ns. If this field is
required to be any value other than the default, BIOS must initialize it accordingly.
Active State Link PM Support
L0s & L1 entry supported.
Max Link Width
Hardwired to indicate x8.
When Force x1 mode is enabled on this PCI Express x8 link device, this field reflects
x1 (01h).
Max Link Speed
Hardwired to indicate 2.5 Gb/s.
