Hello all, Jeff Garzik in particular,
we have interest in having the Marvell 88sx5040 SATA controller work
under libata.
Did you happen to start development for this controller, as your
latest libata status report seems to tell so?
We have the Marvell datasheet available (but under NDA) as well as
the source code from SuperMicro and we would like to convert it to
the libata framework.
Regards,
Leon.

In fact, I am working on it right now.
I also have the docs and the driver (albeit officially :)).
A non-queueing driver for Marvell will be fairly straightforward.
Adding queueing will be much more of a chore, though.

Excellent. Applying as test-bed candidate. :-)

I happen to find it at this public customer support FTP server:
ftp://ftp.supermicro.com/driver/SATA/DAC_SATA-MV8/
which is officially for the MV8 PCI card, which has the forementioned
chip on its PCB.

That makes me wonder, what is the typical performance gain when using
any of the command queueing methods?

Leon.
