PQI or AHCI) and set the value of the Base Address by selecting Tools > PCIe SSD Base
Address Mapping. The PCIe SSD Configuration dialog displays (see
Figure 10.30 on
page 205 ).
From software release 6.63 onwards, users are able to decode NVMe/PQI traces which
are lacking configuration space and administration information and from release 6.70 this
is applicable to AHCI traces. Users have to follow the steps below to facilitate this
decoding:
1. Record the trace for NVMe/PQI, AHCI or ATA device boot and decode it.
This saves the configuration space and administration information in .xml format,
which is used to decode traces with only IO commands.
2. Record the trace of the same NVMe/PQI, AHCI or ATA device without rebooting and
the application will decode it.
You can keep recording and decoding until rebooting. On reboot repeat steps 1 and 2
above.
10.22.1 NVMe PCIe SSD Device Configuration
The PCIe SSD Configuration dialog is used to add missing information to decode the trace
without the configuration space and queue administration information. See
Figure 10.30
on page 205 for NVMe PCIe SSD Device Configuration.
Prior to decoding, if every thing is available in Configuration Space then Source equals
Config Space (see
Figure 10.30 on page 205 ).
