6.2.42 SLOTCTL - Slot Control
B/D/F/Type: 0/6/0/PCI
Address Offset: B8-B9h
Default Value: 0000h
Access: RO; RW
Size: 16 bits
PCI Express Slot related registers allow for the support of Hot Plug.
14:7 RW-O 00h Core Slot Power Limit Value (SPLV)
In combination with the Slot Power Limit Scale value, specifies
the upper limit on power supplied by slot. Power limit (in
Watts) is calculated by multiplying the value in this field by the
value in the Slot Power Limit Scale field.
If this field is written, the link sends a Set_Slot_Power_Limit
message.
6RO 0bCoreReserved for Hot-plug Capable (HPC)
When set to 1b, this bit indicates that this slot is capable of
supporting hot-lug operations.
5RO 0bCoreReserved for Hot-plug Surprise (HPS)
When set to 1b, this bit indicates that an adapter present in
this slot might be removed from the system without any prior
notification. This is a form factor specific capability. This bit is
an indication to the operating system to allow for such removal
without impacting continued software operation.
4RO 0bCoreReserved for Power Indicator Present (PIP)
When set to 1b, this bit indicates that a Power Indicator is
electrically controlled by the chassis for this slot.
3RO 0bCoreReserved for Attention Indicator Present (AIP)
When set to 1b, this bit indicates that an Attention Indicator is
electrically controlled by the chassis.
2RO 0bCoreReserved for MRL Sensor Present (MSP)
When set to 1b, this bit indicates that an MRL Sensor is
implemented on the chassis for this slot.
1RO 0bCoreReserved for Power Controller Present (PCP)
When set to 1b, this bit indicates that a software
programmable Power Controller is implemented for this slot/
adapter (depending on form factor).
0RO 0bCoreReserved for Attention Button Present (ABP)
When set to 1b, this bit indicates that an Attention Button for
this slot is electrically controlled by the chassis.
