Negotiated Link Width
PSN: Physical Slot Number
This field indicates the physical slot number connected to the PCI Express
port. It should be initialized to 0 for ports connected to devices that are either
integrated on the system board or integrated within the same silicon such as
the Root port in
Reserved.
SPLS: Slot Power Limit Scale
This field specifies the scale used for the Slot Power Limit Value.
Range of Values:
00: 1.0x
01: 0.1x
10: 0.01x
11: 0.001x
SPLV: Slot Power Limit Value
This field specifies the upper limit on power supplied by slot in conjunction
with the Slot Power Limit Scale value defined previously.
Power limit (in Watts) = SPLS x SPLV
HPC: Hot-Plug Capable
This field defines hot-plug support capabilities for the PCI Express port.
0: indicates that this slot is not capable of supporting hot-plug operations.
1: indicates that this slot is capable of supporting hot-plug operations
HPS: Hot-Plug Surprise
This field indicates that a device in this slot may be removed from the system
without prior notification.
0: Indicates that hot-plug surprise is not supported
1: Indicates that hot-plug surprise is supported
The Intel 5000P Chipset MCH does not support hot-plug surprise feature.
