Decoding Traffic Teledyne LeCroy
6.13.4 NVM
NVM level decode displays NVMe transactions. PETracer decodes the storage
commands starting from lower Transaction Layer decodes. In the case of NVMe, it will
decode first the Packet Level, then the Link Transaction level, then the Split Transaction
Level and finally the NVME decode level.
Note: The trace must contain the device enumeration sequence so the decoding picks up the
associated base addresses and NVMe transactions can be properly decoded. If the enumeration
sequence is not available the base addresses must be manually entered in the PCIe SSD
Configuration dialog from the Tools menu.
6.13.5 PQI
PQI level decode displays PQI transactions. PETracer decodes the storage commands
starting from lower Transaction Layer decodes. In the case of PQI, it will decode first the
Packet Level, then the Link Transaction level, then the Split Transaction Level and finally
the PQI decode level.
6.13.6 AHCI
AHCI level decode displays AHCI transactions. PETracer decodes the storage
commands starting from lower Transaction Layer decodes. In the case of AHCI, it will
decode first the Packet Level, then the Link Transaction level, then the Split Transaction
Level and finally the AHCI decode level.
