0 = The VC negotiation is complete.
1 = The VC resource is still in the process of negotiation
Software may use this bit when enabling or disabling the VC.
This bit indicates the status of the process of Flow Control
initialization. It is set by default on Reset, as well as
whenever the corresponding Virtual Channel is Disabled or
the Link is in the DL_Down state. It is cleared when the link
successfully exits the FC_INIT2 state.
Before using a Virtual Channel, software must check whether
the VC Negotiation Pending fields for that Virtual Channel are
cleared in both Components on a Link.
Virtual Channel 1 Negotiation Pending (VC1NP)
Traffic Class/Virtual Channel Map (TCVCM)
Indicates the TCs (Traffic Classes) that are mapped to the
VC resource. Bit locations within this field correspond to TC
values.
For example, when Bit 7 is set in this field, TC7 is mapped to
this VC resource. When more than one bit in this field is set,
it indicates that multiple TCs are mapped to the VC
resource. In order to remove one or more TCs from the TC/
VC Map of an enabled VC, software must ensure that no new
or outstanding transactions with the TC labels are targeted
at the given Link.
BIOS Requirement: Program this field, including Bit 0, with
the value 00100010b (22h), which maps TC1 and TC5 to
VC1.
Traffic Class 0/Virtual Channel 1 Map (TC0VC1M)
Traffic Class 0 is always routed to VC0.
