Description
Physical Descriptor Destination ID. These bits define which port to route the request to
if it is a hit based on the other settings in this register.
000: Port 0 (GLIU)
001: Port 1 (GLPCI_SB)
010: Port 2 (USBC2)
011: Port 3 (ATAC)
Physical Compare BIZZARO Flag.
0: Consider only transactions whose BIZZARO flag is low as a potentially valid address
1: Consider only transactions whose BIZZARO flag is high as a potentially valid address
Reserved. Write as read.
Physical Memory Address Base. These bits form the matching value against which the
masked value of the physical address bits [31:12] are directly compared. If a match is
found, then a hit is declared, depending on the setting of the BIZZARO flag comparator.
Physical Memory Address Mask. These bits are used to mask physical address bits
[31:12] for the purposes of this hit detection.
hit. A low BIZZARO flag indicates a normal transaction cycle such as a memory or
I/O.
hit. A high BIZZARO flag indicates a ‘special’ transaction, such as a PCI Shutdown or
Halt cycle
