[9fans] SATA VT8251 support?

[9fans] SATA VT8251 support?

[gdiaz]

Hi

did anyone know if this controller is supported by the sata driver?

i cant see anywhere in sdata.c and sdiahci.c. . . i guess it isnt supported at all, so there is no option to fill some "silly" pci-id somewhere to get it going.

The new 9grid.es server has this controller, it would be a pitty not being able to run plan9 on it and be stuck to the 256M-RAM server :(

(output of lspci -v under the linux the server comes with)

thank you very much,

i didn't add support because i didn't have any test hardware.
please try the untested version at http://www.quanstro.net/sdiahci.c.
it should report the via as an unk 4-port hba.  "unk" means that there
is no special magic required.

do you need a matching driver for 9load?

try http://www.quanstro.net/sdiahci.c.

i hadn't enabled this in the release version because i didn't
have any hardware on which to test.  let me know how this
works for you.

Hi Erik,

I try it this morning, but the server don't boot. I cannot say nothing
about the problem, because the server is "far far away" and we don't have
console.

Probably we need change the 9load to include this SATA support.

Any help?

Thanks Eric,

slds.
