Hello all

I have some questions about SATA interface

1. 48-bit addressing  is supported or not?

2. FIS-based Switching is supported or not?

Sincerely,Max Chou

    Hi,

    1. Yes, 48-Bit addressing is supported. This is firmware/ s/w / driver related as opposed to h/w. So long as your application firmware supports 48-bit addressing, no issue with the h/w.

    2. No we do not. We have stated the support for the AHCI 1.1 Specification. This specification clearly indicates that Command Based Switching is the only one supported. See CAP[FBSS] field description. This field should be/is ZERO.

    Best regards, Zegeye
