Well, I implemented PCI probing as per the UltraSparc IIi user's manual,
and now, I get quite a bit more than I bargined for:
bash-2.05b$ pciconf -l | wc
38 228 3106
The complete pciconf -l -v is at:
http://people.freebsd.org/~jmg/pciconf-lv.sparc64
Now, I seem to be getting duplicates on some functions, and then of
course, I am now seeing the firewire part of the SME2300BGA that doesn't
have a phys attached to it. (The driver does attach to the firewire
part, but fails trying to talk to the phys.)
This also required updating the pci_read_device to ignore a all zero
return value for PCIR_DEVVENDOR, and not probe higher functions in
that case. If I tried to probe higher functions (such as 0.0.2), the
system would hang.
A dmesg output of the boot is at:
http://people.freebsd.org/~jmg/dmesg.sparc64
I don't include the dmesg that shows me attaching the firewire driver.
I have posted the patch to produce this at:
http://people.freebsd.org/~jmg/sparc.patch
Warning, this contains much debugging data, and probes for PCI devices
that previously didn't get probed for.
