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.
Note: The trace must contain the device enumeration sequence so the decoding
picks up the associated base addresses and AHCI 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.
ATA
ATA level decode displays ATA transactions. PETracer decodes the storage
commands starting from lower Transaction Layer decodes. In the case of ATA, it
will decode first the Packet Level, then the Link Transaction level, then the Split
Transaction Level, then AHCI level and finally the ATA decode level.
Note: The trace must contain the device enumeration sequence so the decoding picks
up the associated base addresses and ATA 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.
