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. Because only 
bit 0 of that field is asserted.   This field will 

always be programmed to '1'. 

16:8 RO  000h Core 

7:1 RW  7Fh Core 

Traffic Class / Virtual Channel 0 Map 
(TCVC0M):  
 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. 

0 RO  1b Core 

Traffic Class 0 / Virtual Channel 0 Map 
(TC0VC0M): 
Traffic Class 0 is always routed to VC0. 

B/D/F/Type: 0/0/0/DMIBAR

Access:  

RO; 

Size: 16 

bits 

Reports the Virtual Channel specific status. 

 

 

15:2 RO  0000h Core 

Reserved ():  
  Reserved and Zero for future R/WC/S 
implementations. Software must use 0 for 
writes to these bits. 

1 RO  1b Core 

Virtual Channel 0 Negotiation Pending 
(VC0NP):  
0: The VC negotiation is complete. 
1: The VC resource is still in the process of 
negotiation (initialization or disabling).   This bit 

indicates the status of the process of Flow
