Hi All, I am working on an AHCI SATA controller. For each port, there is one FIS descriptor and one Command List, which points to a Received FIS structure and Command List structure. So what is Received FIS structure? The Command List structure points to Command Table, that has Command FIS field and Physical Region Descriptor table. I assume the Command table is used for the communication between processor and the SATA controller. Then why do we need the Received FIS structure? Thanks for your help, Mike - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
