Silicon Image 3112 h/w docs available

Silicon Image 3112 h/w docs available

[Jeff Garzik]

In order to better support open source developers, Silicon Image has 
been kind enough to give me permission to publicly post the hardware 
documentation for some of their older SATA chipsets on my docs site, 
namely the 3112 in this case:

http://gkernel.sourceforge.net/specs/sii/3112A_SiI-DS-0095-B2.pdf.bz2

This documentation will assist developers in maintaining the 
siimage/sata_sil SATA drivers in the Linux kernel.

So now the 311x joins the ranks of "open hardware".  Thanks, SiI!

Doesn't seem to contain any more info on drives/controllers affected by
the mod15write quirk.  I'd like to see firmware revisions added to the
blacklist, and not just model numbers anymore.  I didn't have that
information when I first implemented the blacklist (model numbers only),
and it still doesn't seem to be available right now.

I'm rather disappointed that the drive (ST3160023AS) I use has managed
to get its way onto the blacklist[1].  I'm using rev 3.05 of that drive
with a 3112 (rev 02), and have been for nearly a year at full speed and
have never had problems under heavy read/write usage.  Setups affected
by an uncorrected mod15write bug are corrupted almost immediately, no?

My understanding is that there's nothing to put in a SI3112 spec
regarding this issue.

The card follows the specification correctly.  The issue is some
drives don't handle this "legal but unexpected" behavior.  That issue
(in theory) would be for the drive vendors to document.
