LSI Logic 1068E and SATA port replicators (Sil3726)

[Martin Scholl <ms@diskware.net>]

Hello all,


[disclaimer: what follows is probably a really stupid idea after all.]

We would like to use a LSI SAS 1068E board with Sil3726 SATA port
replicators. This obviously "fails" in that only 1 disk out of the 5
connected is actually visible.

I found, if SATA drivers are to support a port multiplier, they inhert
from sata_pmp_port_ops. Is an analog infrastructure available for the
sas-based HBAs to support SATA port multipliers? (BTW is such a setup
actually supported form a protocol point of view?)

I'm not a regular kernel hacker, so I cannot really help you in getting
quality sata mpm support (if possible after all) into the sas drivers.
What I can definitely offer is my time and will to test the driver
modifications you would send me.
