PID
GLD_MSR_CONFIG Bit Descriptions
Bit Name Description
63:11 RSVD Reserved.
10:8 PRI1 Secondary Priority Level. This value is the priority level the VIP uses when performing
high priority GLIU accesses. This is the case when the FIFO is nearly full.
7 RSVD Reserved.
6:4 PRI0 Primary Priority Level. This value is the priority level the VIP uses for most accesses
(i.e., when the VIP FIFO is not in danger of being full).
3 RSVD Reserved.
2:0 PID Priority ID. This value is the priority ID (PID) value used when the VIP initiates GLIU
transactions.
