hi, The SATA spec defines DMA setup FIS auto-activate optimization for FPDMA transfers. I had an attempt to add it, though my test doesn't show obvious performance improvement (not worse too), I wonder why not add this feature? Signed-off-by: Shaohua Li <shaohua.li@xxxxxxxxx>
I agree, we should turn it on -- but doesn't this also have a controller dependency?
IIRC, not all NCQ-capable controllers support this feature... SATA 1.0 hardware may not behave properly in response, no?
