Default
Value
0x0
Message Address. This field specifies the lower portion of
the DWORD address of the MSI memory write transaction.
The PES4T4 assumes that upstream and downstream ports
generated MSIs are targeted to the root. Configuring the
address contained in a port's MSIADDR and MSIADDRU
registers to an address that does not route to the root port
and subsequently generating an MSI produces undefined
results.
Default
Value
0x0
Upper Message Address. This field specifies the upper por-
tion of the DWORD address of the MSI memory write trans-
action. If the contents of this field are non-zero, then 64-bit
address is used in the MSI memory write transaction. If the
contents of this field are zero, then the 32-bit address speci-
fied in the MSIADDR field is used.
The PES4T4 assumes that upstream and downstream ports
generated MSIs are targeted to the root. Configuring the
address contained in a port's MSIADDR and MSIADDRU
registers to an address that does not route to the root port
and subsequently generating an MSI produces undefined
results.
Default
Value
0x0
Message Data. This field contains the lower 16-bits of data
that are written when a MSI is signalled.
0x0
Reserved field.
Default
Value
0xD
Capability ID. The value of 0xD identifies this capability as a
SSID/SSVID capability structure.
0x00
Next Pointer. This field contains a pointer to the next capa-
bility structure.
0x0
Reserved field.
