Hi,

 since SATA does not support DMA I would be interested in other ways
 to tune the SATA interface.

Huh?  SATA _does_ support DMA, and it is always enabled.

 Does someone knows some working things to do for tuning the SATA
 interface?

If you have chosen the correct driver in the your kernel
configuration, it is self-tuning.  There is no more performance to be
had generally.

What problem are you trying to solve?  What does "hdparm -Tt /dev/sda"
actually report?
