Detailed Description

9.7.0.1 V1C09-060 RELIABLE SERVICE COMPLETION RULES

Abstract: This test verifies the completion rules for Reliable Services.

Coverage: v1c09-060

Topology Configuration: SimpleLink: Tester=Transport Tester; Width=1X, 4X, or 12X; DUT=xCA

DUT Qualifiers: Must be able to support 2 outstanding requests before requiring an ACK.

Notes:

1. If the DUT requires an ACK for each request posted on the SQ, we will timeout on the second TransportRxIbPacket() command. For this behavior, the DUT should have set the AckReq bit in the first message to demand an ACK. We are not checking AckReq in this test.
2. We could change the test to conditionally send an ACK if the AckReq bit is set but do not feel that anyone would have such an implementation that only supported one outstanding request at a time.

9.7.0.1.5 V1C09-060 RC RDMA Read Case

Assertions: V1c09-060#05

Notes:

• The DUT (as requester) will post a RC RDMA Read request but will not complete until the TT (as responder) returns an ACK covering all the request packets transmitted for that message.
• Variable CC as structure of type ChannelContext_t
• Variable READWQE as structure of type RcReadDut_t
• Variables PACKET_IN, PACKET_OUT as structure of type PacketType_t
• Variable COMPLETE as structure of type PollDut_t
• Variable N of type Integer for loops

Test Procedure

initialize()

boolean initialize ( ) throws TestException

protected

Initialization:

1. OpenRcChannel( CC ) // (reliable connection)

2. Set QP ACK timeout = 0 (infinite) so that the DUT will not retransmit

execute()

boolean execute

(

)

throws TestException

Test Procedure:

1. Register memory region for receiving remote packets

2. Post one receive request for each expected packet from DUT

3. Transmit 2 RC READ WQEs from DUT at size (3 * PMTU). Each response message will contain 3 packets.

   • READWQE.MsgSize = 3 * CC.PMTU
   • READWQE.Count = 2
   • WRITEWQE.R_KEY = 0x12345 // User specified R-Key
   • WRITEWQE.VA = 0x999000 // User specified VA
   • PostRcRdmaWr( CC, READWQE )

4. Receive all expected packets

5. Verify all packets were received and were valid

6. Verify each message contained a single Read Request packet with incrementing PSN

7. Transmit response packets to acknowledge the first Read request (MSN = 1)

8. Transmit Read Response First Packet

   • PACKET_OUT.HeaderMask = LOCAL | READ_FIRST
   • PACKET_OUT.BTH_OpCode = RC_READ_FIRST
   • PACKET_OUT.AETH_Syndrome = ACK
   • PACKET_OUT.AETH_MSN = 1
   • CC.TT_TxRespPSN = Mod( CC.DUT_Start_PSN + 0, 24)
   • TransportTxPacket( CC, PACKET_OUT )

9. Transmit Read Response Middle Packet

   • PACKET_OUT.HeaderMask = LOCAL | READ_MID
   • PACKET_OUT.BTH_OpCode = RC_READ_MID
   • CC.TT_TxRespPSN = Mod( CC.DUT_Start_PSN + 0, 24)
   • TransportTxPacket( CC, PACKET_OUT )

10. Transmit Read Response Last Packet

    • PACKET_OUT.HeaderMask = LOCAL | READ_LAST
    • PACKET_OUT.BTH_OpCode = RC_READ_LAST
    • PACKET_OUT.AETH_Syndrome = ACK
    • PACKET_OUT.AETH_MSN = 1
    • CC.TT_TxRespPSN = Mod( CC.DUT_Start_PSN + 0, 24)
    • TransportTxPacket( CC, PACKET_OUT )

11. Poll for completion of first Send message on DUT's send queue

12. Verify exactly 1 work completion was dequeued from the send queue

13. Verify that the status of the work completion indicates successful completion

14. Poll for completion of second Send message on DUT's send queue

15. Verify second WQE will not complete as it has not been acknowledged. There will be a timeout waiting for this to happen.

16. CloseRcChannel( CC )

    • Remark: Flush unacknowledged WQE.
