Description
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 Intel 5000P Chipset MCH.
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.
PIP: Power Indicator Present
This bit indicates that a Power Indicator is implemented on the chassis for this
slot.
0: Indicates that Power Indicator is not present
1: Indicates that Power Indicator is present
AIP: Attention Indicator Present
This bit indicates that an Attention Indicator is implemented on the chassis for
this slot.
0: Indicates that an Attention Indicator is not present
1: Indicates that an Attention Indicator is present
