PCIe Device and Address Mappings
The PCIe Analyzer remembers the devices and address mappings from a prior boot-up sequence in
order to analyze and decode future traces. You can manually enter all the devices and addresses in
the
Devices And Addresses
dialog. Expert automatically generates those mappings when it
processes a boot-up sequence. To open the dialog, click the Devices And Addresses button
in TraceControl’s toolbar, or select
Devices and Addresses
from the
Tools
menu. This button is
enabled when you lock PCIe ports.
The
On the Current Port(s)
tab in the
Devices And Addresses
dialog shows the mapping stored
in a file on the chassis. If there are multiple chassis in a domain, the contents of this tab is always
the information for the first port pair listed in the domain. The contents of this tab can also be
retrieved from any PCIe chassis in the domain.
Figure 36: Devices And Addresses Dialog
When a capture stops, TraceControl copies the device mapping from the first domain port into the
pre-capture.devices file for the domain so that every capture's pre-capture.device file is initialized
from TraceControl's domain device mapping.
The devices and addresses mapping is mandatory for TraceView and Expert to decode any
protocols over PCIe, such as NVMe or SATA-AHCI. The information is exchanged during the
boot sequence between the host and the devices. It may change from one reboot to the next.
You can fill the device mapping in two ways. First, you can click the “Automatically filling this
dialog” hyperlink at the top of the dialog. When you do, a popup appears instructing you how to
fill the dialog automatically. Second, you can enter the information manually. The buttons on the
dialog's right-hand side allow you to add or remove devices, queues, and addresses.
