6:6
RO
0x0
t:
Applies only to root ports. This is hardwired to 0b as the
component does not implement ACS Direct Translated
P2P.
5:5
RO
0x0
e:
Applies only to root ports. The component does not
implement ACS P2P Egress Control and hence this bit
should not be used by SW.
4:4
RW_L (Device 2 and 3
Function 0)
RW (Device 0 Function 0,
Device 2 and 3 Function 1-3)
0x0
u:
When this bit is set, transactions arriving from a root
port that target the same port back down, will be
forwarded. Normally such traffic would be aborted.
Applies only to root ports.
3:3
RW_L (Device 2 and 3
Function 0)
RW (Device 0 Function 0,
Device 2 and 3 Function 1-3)
0x0
c:
Applies only to root ports. Determines when the
component redirects peer-to-peer Completions
upstream; applicable only to Read Completions whose
Relaxed Ordering Attribute is clear.
2:2
RW_L (Device 2 and 3
Function 0)
RW (Device 0 Function 0,
Device 2 and 3 Function 1-3)
0x0
r:
When this bit is set, transactions arriving from a root
port that target the same port back down, will be
forwarded. Normally such traffic would be aborted.
Applies only to root ports.
1:1
RW_L (Device 2 and 3
Function 0)
RW (Device 0 Function 0,
Device 2 and 3 Function 1-3)
0x0
b:
Applies only to root ports. When set, the component
blocks all upstream Memory Requests whose Address
Translation AT field is not set to the default value.
