System Response
The following table describes the parameter meanings.
Parameter |
Meaning |
|---|---|
| Range | I/O size, such as 512 bytes and 4096 bytes. |
| R/W | Read/Write request type. |
| TYPE | Minimum/Average/Maximum I/O latency in each phase. |
| IO Count | I/O request count. |
| PostToMid | Time when the target driver sends the I/O command to MTGT. |
| TgtXferRdy | Time when the MTGT completes write allocation and sends XferRdy to the driver. |
| XferWaitDone | Time when the target driver adds XferRdy to the wait list. |
| HwXferRdy | Time when the target driver sends XferRdy to the chip. |
| HwXRdyDone | Time when the target driver adds XferRdy to the chip queue. |
| RxData | Time when the chip receives write request data and sends it to MTGT. |
| TgtRsp | Time when MTGT sends a response to the driver after MTGT completes reads and writes. |
| RspWaitdone | Completion time when the target driver adds a response to the wait list. |
| HwRsp | Completion time when the target driver sends a response to the chip. |
| HwRspDone | Completion time when the target driver adds the response to the chip queue. |
| A-->B | Time required for a response added to the queue after the target driver sends the response. |
| CmdDone | Time when the target I/O command is completed. |
