Query about SIS963 Bridges

Please CC me on [email protected] without the spam as I'm not subscribed - thanks.

I've just got a new machine (2.5 GHz pentium lots of RAM and disk space) which has one of these SIS963 Southbridge creatures and I get the message on booting a 2.4.19ish sort of kernel.

Unknown bridge resource 0 - assuming transparent

Alas it's very clear that it isn't transparent and I can't get to half of the PCI stuff - worst of all the built-in Ethernet and any Ethernet card I plug in. It would seem that it isn't too transparent as the reported IRQ and IOMEM assignments for the devices are all scrambled.

I changed the message in drivers/pci/pci.c to report the base and limit values extracted and they are e000 and d000 respectively which explains why the code chokes on it.

I've followed a long thread about fixing this on transparent bridges - can some kind guru give me some runes to get this machine off the ground? A quick and dirty my-machine-only hack would be fine for me if not fully aesthetically pleasing to all and sundry.

I've looked at the SIS website and it wasn't a lot of help. They referred me to the motherboard mfr (ASUS). I emailed ASUS but still no joy.

I see the built-in Ethernet is an SIS900 no doubt that is more fun in store with that but I've got a small stack of alternative PCI cards on the windowsill which I'll stuff in if I can get past this problem.

The SiS963 is currently a winputer.

One possibility is the system expects ACPI to untangle that mess and set up the bridge. You could certainly stuff realistic looking ranges into it, set IO/MEM and master and see what happens then

What would be a useful starting point would be to see what lspci -vxx and lspci -vxx -H1 think

Here are the relevant bits out of "lspci -vxx"

(There's no difference in the output for the SIS963)

I'll have a look at APCI later today.

Can you try

lspci -vxx -H1 -M

and see if thats different

Here's the output

I have managed to persuade the suppliers that as I told them I was going to run Linux on it in advance and because the motherboard manual clearly says only Windrosses are supported (not quite in those terms), they'll swap the motherboard for me.

They can offer one with the Intel 7205 chipset, supposedly the "bees knees" or one with the 845 chipset which apparently has been around for a while but doesn't have the performance rating.

Could anyone advise me whether I would be OK with either of those, preferably the higher performance one of course? As I'm being paid to hack user-level software, whilst it doesn't terrify me, I'd prefer not to dive too much into the bowels of PCI code right now.

Whilst I'm waiting for the new motherboard to appear I'll be pleased to try out anything including any patched PCI modules for a 2.4.19 kernel anyone wants me to on the motherboard I've got. But please remember that I have to transfer everything on floppies because the network doesn't work!

Thanks for everyone's help.

Just to say I got the Intel 7205 Chipset motherboard and everything is going fine - lightning fast in fact.

Still a message about Unknown bridge resource and something about device 00:1f.1 not available becuase of resource collisions but as everything I want to use seems to work presumably it doesn't matter. I disabled all the stuff I'm not using at the moment such as Firewire. If anyone wants the output of lspci give me a shout.

Thanks to all who helped anyhow.

Nooooooooo!
Arrgh !
darn
no wonder my setup is broken after that H/W upgrade

2.2.20 actually works with my PCI NIC (no support for my paradise ATA) 2.4.x does not work with nic or (00:0b.0 Unknown mass storage controller:
Promise Technology, Inc.: Unknown device 4d68 (rev 01) )
2.4.20 slackware 9.0 bare.i works with the PCI NIC and PCI ATA card (no acpi in this kernel)

is ACPI the problem with this chipset ?

I'd like to get this board working is there any information I can provide that would give you another data point ....

Just tell me which kernel/patch and what info you need..

When you choke a smurf, what color does it turn?

It might be. I don't have time to find out and SiS clearly don't care about their customers any more

ob IANAL ...

It seems to me that if SIS has provided the chipset docs to Microsoft, then a polite note from Redhat legal that mentions "RESTRAINT OF TRADE" might work wonders. Perhaps Alan could get the RH lawyers involved.

Regards,

John

And what good would that do ?

At the moment I'm trying to get them to talk sanely about workable NDA's with vendors.

ACPI on and UP+APIC off Works for me, if anyone cares.
