AHCI data
The AHCI (advanced host controller interface) and the associated SATA (serial ATA) commands
for storage devices are displayed on the Transaction Decode window. By capturing the setup
information, the configuration is automatic, and the parts of a command are joined together to
display the complete operation.
Figure 9. The decoded transactions are a mix of PCIe Config, generic host control, port-specific, and SATA commands transactions.
Figure 10. An AHCI transaction shows in the Transaction Decode tab as a super transaction, allowing its complete set of related transactions to be
viewed.
