It will say something like the following. ata1.00: ATA-7, max UDMA7, 312581808 sectors: LBA48 NCQ (depth 31/32) If your controller doesn't support NCQ, it will say 0/32. ATM, libata caps max supported commands to 31, so you'll see 31/32 for NCQ capable drives. > 2. The sata_sil24 and sata_sil drivers support suspend. Can you explain > this in more detail?
