Request Compare Value (GLIU_RQ_COMP_VAL)

The RQ Compare Value and the RQ Compare Mask enable traps on specific transactions. A hit to the RQ Compare is

determined by hit = (RQ_IN & RQ_COMP_MASK) == RQ_COMP_VAL). A hit can trigger the RQ_COMP error sources

when they are enabled. The value is compared only after the packet is arbitrated.

3HIT_ERR

Assert AERR on Descriptor Hit. This bit causes an asynchronous error to be generated

when a matching descriptor hit occurs, or not. The descriptor hits are ANDed with the

masks and then all ORed together.

0: Disable.

1: Enable.

2HIT_SMI

Assert ASMI on Descriptor Hit. This bit causes an ASMI to be generated when a

matching descriptor hit occurs, or not. The descriptor hits are ANDed with the masks and

then all ORed together.

0: Disable.

1: Enable.

1HIT_DEC

Decrement Counter on Descriptor Hit. This bit causes the associated counter to dec-

rement when a matching descriptor hit occurs, or not.The descriptor hits are ANDed with

the masks and then all ORed together.

0: Disable.

1: Enable.

0HIT_LDEN

Load Counter on Descriptor Hit. This bit causes the associated counter to reload its

LOAD_VAL when a matching descriptor hit occurs, or not.The descriptor hits are ANDed

with the masks and then all ORed together.

0: Disable.

1: Enable.

RQ_COMPVAL

Request Packet Value. This is the value compared against the logical bit-wise AND of

the incoming request packet and the RQ_COMP_MASK in order to determine a hit.
