Hi,
I've got a VIA SATA/PATA PCI RAID card installed in a MIPS box, which
obviously doesn't run the BIOS on the card.
When booting these messages appear....
PCI: Enabling device 0000:00:0a.3 (0000 ->
0003)
sata_via 0000:00:0a.3: routed to hard irq line

ata3: port is slow to respond, please be patient (Status
0x8c)
ata3: device not ready (errno=-16), forcing hardreset
Now, the 8C8C8C8C is suspicious because the card hasn't had the BIOS
executed, so something isn't getting initialized. As it's the same for
even the PATA port with 0x8c.
Any ideas ?
Alan.

The docs list a range of Phy setup and power registers, but not enough
information on how to configure them for a given board. Some look like
they will be board specific as well. Probably best to ping VIA and see if
you can get the relevant programming guide, that and/or copy register
settings from a PC

None for VIA specifically, but I long ago had a similar (but
less severe) problem with a sata_promise card in a sparc64 box.
What I ended up doing was to
1. put the card in an x86 box, boot, and dump its PCI config
space with lspci
2. put the card in the non-x86 box, boot, and dump its PCI config
space with lspci
3. compare the PCI config spaces from steps 1 and 2, note any
differences, and study manual/datasheet/driver to see what
the diffs might mean
4. add missing initialisations to the Linux driver

Care to post lspci -nn?

I still need to do Mikael's suggestion of plugging it into an x86 box
and checking it's PCI config space.

I was hoping it was 5287 which sata_via currently doesn't fully support.
I think you'll need to try the PCI config space trick.
Thanks.

I dumped the PCI config space via "lspci -xxx" and this is the diff
compared to an x86 box.

I think the b0 line differences are to do with me not having an 80core
cable plugged in on the x86 box, and I did on the mips.
The other earlier stuff looks reasonable as it's probably just the
mem&io ranges.
If others can take a peek and spot anything obvious I'd be glad to try
it here.
If there's nothing obvious, then I guess it's deeper MMIO register
poking ??
Alan.
