Supported chipsets with sata_sil24?

Supported chipsets with sata_sil24?

[John Woznack]

Out of curiosity, which Silicon Image chipsets are supported by the
sata_sil24 driver? (3124/3132 obviously, but what about 3512, 3112, 3531,
and 3726?)

sata_sil24	: 3124, 3132, 3131, 3531
sata_sil	: 3112, 3114, 3512 and some other variants

3726 and 4726 are port multipliers and supported by pending PMP patchset.

Thanks Tejun. Just what I was looking for.

After checking out http://linux-ata.org/driver-status.html, I've got Just a
few more questions: 

1. The sata_sil24 shows it supports NCQ. Out of curiosity, how can I tell
if it's using NCQ? 

2. The sata_sil24 and sata_sil drivers support suspend. Can you explain
this in more detail? (Like, is it always on or do I have to enable it? Can
I set the idle timeout-to-suspend somehow? etc.)

Thanks!

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.

If the power management is turned on, those are turned on automatically.
