Table 17 Process Element Features CAR
Address:
Extended Addressing Support:
Indicates the number of address bits supported by the PE both as a
source and target of an operation.
3b001 indicates support for 34 bit addresses.
Extended Features:
PE has extended features list; the extended features pointer is valid.
Common Transport Large System Support:
When enabled it indicates support for 16 bit source and destination ID’s.
Critical Request Flow Support:
1b0 - PE does not support CRFS
1b1 - PE supports CRFS
SerB does not support CRFS, hence this bit is hard wired to zero.
Re-transmit Suppression Support:
1b0 - PE does not support RTSS
1b1 - PE supports RTSS
SerB does not support RTSS, hence this bit is hard wired to zero.
Flow Control Support:
SerB does not support FCS,
Standard route table configuration support:
SerB does not support SRTCS,
Extended route table configuration support:
SerB does not support ERTCS,
Multicast Extension Support:
SerB does not support Multicast,
Reserved.
Indicates that the RIO controller supports inbound doorbells.
Mailbox 3:0:
Bt 0 indicates PE supports inbound mailbox 0.
Bit 1 indicates PE supports inbound mailbox 1.
Bit 2 indicates PE supports inbound mailbox 2.
Bit 3 indicates PE supports inbound mailbox 3.
Reserved.
Indicates that the PE can bridge to another external RIO interface.
Indicates that the PE physically contains a local processor that executes
code.
Indicates that the PE has physically addressable local address space and
can be accessed as an endpoint through non-maintenance operations.
Indicates that the PE can bridge to another interface.
0x00010
hence this bit is hard wired to zero.
Comment
hence this bit is hard wired to zero.
hence this bit is hard wired to zero.
hence this bit is hard wired to zero.
