I'm getting stuck in Hypertransport enumeration. Is there supposed to be a
pci_domain that is the child of a HT link? If so, what device ID would it
have.
I'm thinking specifically about the 8132 and 8111 on the Serengeti board.
The dts currently looks like this (simplified):
[EMAIL PROTECTED] {
/config/("northbridge/amd/k8/domain");
[EMAIL PROTECTED],0{
};
[EMAIL PROTECTED],0 {
/config/("northbridge/amd/k8/pci");
[EMAIL PROTECTED],0 {
/config/("southbridge/amd/amd8111/pci.dts");
[EMAIL PROTECTED],0{
/config/("southbridge/amd/amd8111/nic.dts");
};
[EMAIL PROTECTED],0{
/config/("southbridge/amd/amd8111/usb.dts");
};
};
[EMAIL PROTECTED],0 {
/config/("southbridge/amd/amd8111/lpc.dts");
};
};
I think it should look like this:
[EMAIL PROTECTED] {
/config/("northbridge/amd/k8/domain");
[EMAIL PROTECTED],0 {
/config/("northbridge/amd/k8/pci");
[EMAIL PROTECTED],0 { //Really at 00:6.0
/config/("southbridge/amd/amd8111/pci.dts");
[EMAIL PROTECTED],0{
/config/("southbridge/amd/amd8111/nic.dts");
};
[EMAIL PROTECTED],0{
/config/("southbridge/amd/amd8111/usb.dts");
};
};
[EMAIL PROTECTED],0 { //Really at 00:7.0
/config/("southbridge/amd/amd8111/lpc.dts");
};
[EMAIL PROTECTED],0{ //Really at 00:a.0 and 00:b.0
/config/("southbridge/amd/amd8132/pcix.dts");
};
};
My reasoning is that the 8132 and the 81111 should be at the same level.
This doesn't work for me in hypertransport enumeration for various reasons.
Before I do a big rewrite, I'd like a little sanity check.
By the way, "dynamic" in the dtsname is bad when you had the device in the
dts. It means it didn't find your device where you said it was.
Thanks,
Myles
Myles,
You are right that they should be on the same level. I am not an expert
enough on dts but I think you are on the right path. The devices need to
be put in the correct place so we don't get dynamic. I expect that Ron
will have some comment.
Thanks,
Marc
