Virtual Channel 1 Enable (VC1E):
0: Virtual Channel is disabled.
1: Virtual Channel is enabled. See exceptions below.
check whether the VC negotiation is complete. When VC
Negotiation Pending bit is cleared, a 1 read from this VC
Enable bit indicates that the VC is enabled (Flow Control
Initialization is completed for the PCI Express port). A 0
read from this bit indicates that the Virtual Channel is
currently disabled.
BIOS Requirement:
1. To enable a Virtual Channel, the VC Enable bits for that
Virtual Channel must be set in both Components on a
Link.
2. To disable a Virtual Channel, the VC Enable bits for
that Virtual Channel must be cleared in both Components
on a Link.
3. Software must ensure that no traffic is using a Virtual
Channel at the time it is disabled.
4. Software must fully disable a Virtual Channel in both
Components on a Link before re-enabling the Virtual
Channel.
Reserved
Virtual Channel 1 ID (VC1ID):
Assigns a VC ID to the VC resource. Assigned value must
be non-zero. This field can not be modified when the VC
is already enabled.
Reserved
Port Arbitration Select (PAS):
Configures the VC resource to provide a particular Port
Arbitration service. Valid value for this field is a number
corresponding to one of the asserted bits in the Port
Arbitration Capability field of the VC resource.
Reserved
Traffic Class / Virtual Channel 1 Map (TCVC1M):
Indicates the TCs (Traffic Classes) that are mapped to the
VC resource. Bit locations within this field correspond to
TC values.
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.
Traffic Class 0 / Virtual Channel 1 Map (TC0VC1M):
Traffic Class 0 is always routed to VC0.
Software must use the VC Negotiation Pending bit to
For example, when bit 7 is set in this field, TC7 is
