Capture PCIe Devices and Addresses
Capturing the boot-up sequence is critical for PCIe/NVMe to generate the device mapping file and
queue addresses for decoding NVMe.
Clicking the
Capture PCIe Devices and Addresses
button in TraceControl’s toolbar or
selecting Capture PCIe Devices and Addresses from the Tools menu provides an automated
way of capturing the boot-up sequence. This button is enabled when you lock PCIe ports.
Upon clicking the button or menu selection, TraceControl starts a capture and prompts you to
reboot or re-load the PCIe driver. The status dialog box shown in Figure 40 is displayed to display
the status of the process at every stage. Use the
Abort button to end the process.
Figure 40: Capture PCIe Devices and Addresses Dialog Box
The automated Capture PCIe Devices and Addresses process does the following:
• Loads the appropriate configuration file
• Starts a capture on the current segment
• Waits for the capture to arm, trigger and stop (or stops automatically 30 seconds after it is
armed)
• Runs Expert on the captured trace
• Retrieves the Device Mapping file generated by Expert
• Loads the new detected device mapping in TraceControl
• Reports errors and/or diagnostic messages if the capture did not contain all or insufficient
boot-up information
When the Capture PCIe Devices and Addresses dialog closes, the result of the process is shown in
the TraceControl status bar. The last log that was produced by the button “Capture Devices And
Addresses” can always be seen by clicking the message in TraceControl’s blue status bar (see
Figure 41). The message will disappear when you click on any button.
