Haku-saareyaasha oo ka mid ah:

1. Queue Pair Creation: The host system initiates the process by creating a dedicated Submission Queue (SQ) and Completion Queue (CQ) pair for latency measurement. This isolation prevents interference from other I/O operations. The start addresses and lengths of these queues are configured in the FPGA’s test logic.

   
   

2. Command Injection: The host queues an NVMe command and rings the doorbell, prompting the device to fetch the command from the SQ.

   
   

3. PCIe Transaction Snooping: The device issues a PCIe Transaction Layer Packet (TLP) to fetch the command. The FPGA’s snooping logic monitors for read requests within the SQ address range, retrieves the transaction Tag (a unique identifier for the transaction), and records it internally.

   
   

4. Tag Matching and Timer Start: As the FPGA continues monitoring, it matches the Tag in subsequent response packets, extracts the NVMe command ID from the TLP payload, and starts a high-resolution latency timer—typically driven by FPGA clock cycles in the nanosecond range.

   
   

5. Completion Monitoring and Timer Stop: The FPGA then watches for command completion responses in the CQ address range. When the NVMe command ID in the completion response matches the saved command ID, the timer stops, and the measured latency is reported back to the host.
