Data at the PCIe Layer in msprof_*.json

The following figure shows data at the PCIe layer in the msprof_*.json file.

Figure 1 PCIe layer

**Table 1** Field description
Field	Description
PCIe_cpl	Completion packet that receives write requests, in MB/s. Tx stands for the transmit direction, whereas Rx standards for the receive direction.
PCIe_nonpost	PCIe Non-Post data transmission bandwidth, in MB/s. Tx stands for the transmit direction, whereas Rx standards for the receive direction.
PCIe_nonpost_latency	Transmission latency in PCIe Non-Post mode, in μs. Tx stands for the transmit direction, whereas Rx standards for the receive direction. PCIe_nonpost_latency does not involve the RX. The value is fixed at 0.
PCIe_post	PCIe Post data transmission bandwidth, in MB/s. Tx stands for the transmit direction, whereas Rx standards for the receive direction.

pcie_*.csv File

The file content is formatted as follows.

Figure 2 pcie_*.csv

**Table 2** Field description
Field	Description
Device_id	Device ID.
Mode	Mode. The options are as follows: Tx_p_avg(MB/s): PCIe Post data transmission bandwidth at the transmit direction, in MB/s. Tx stands for the transmit direction, whereas Rx standards for the receive direction. Tx_np_avg(MB/s): PCIe Non-Post data transmission bandwidth at the transmit direction, in MB/s. Tx_cpl_avg(MB/s): Completion packet that receives write requests at the transmit direction, in MB/s. Tx_latency_avg(us): Transmission latency in PCIe Non-Post mode at the transmit direction, in μs. Rx_p_avg(MB/s): PCIe Post data transmission bandwidth at the receive direction, in MB/s. Rx_np_avg(MB/s): PCIe Non-Post data transmission bandwidth at the receive direction, in MB/s. Rx_cpl_avg(MB/s): Completion packet that receives write requests at the receive direction, in MB/s.
Min, Max, Avg	Minimum value, maximum value, and mean value.
