Promise 20376 support

Promise 20376 support

[Marcel J.E. Mol]

Hi,

I've got this Asus A7V8X motherboard that contains a promise 20376
sata-ide (raid) controller. In the latest kernel sources (2.4 and 2.5) 
I don't see any mention of this chip yet. Also a google search does
not reveal much about linux support. 
Is there already any work in progress for it?

-Marcel

No work, no documentation. If its just a SATA bridge with an existing
ATA controller then you may find you can just add the PCI identifiers
and pretend its a 20276. If it has other new and wonderous features you
may be completely screwed

Pity...
According to the motherboard manual the promisce controller supports one ATA133
channel and two Serial ATA  connectors.

Tried to pretend it to be a 20276 but it seems to fail (redhat kernel 2.4.18-18.8.0custom):

Using pci=biosirq makes no difference.

Its memory mapped I/O for one. Ok thats down to Promise providing docs
to someone I guess. Otherwise its a "winputer"

Quite some time ago I had a look at their Windows drivers. From the
driver structure, the function names and the actual register accesses I
had the impression that this chip differs largely from the ATA/ATAPI
Host Adapter Standard as decribed in the ANSI committee T13 document
1510D (which happens to be the basis of most of the Linux ATA/ATAPI
drivers). I may be wrong and happily defer to the opposite.
