Well, I've managed to get an XP900 to play with this week, and have added in support to the resource manager to handle the USB controller on Alphas with the cia and tsunami chipsets. According to Doug Rabson: The USB hardware on this platform interrupts via the ISA pic. SRM represents this as an interrupt pin of 0xe0 + isa irq no. Unfortunately I have not put in support in the alpha pci code to recognise this so the interrupt allocation fails. The place to add this support is probably pci_alloc_resource() in sys/alpha/pci/pcibus.c. Not having much to do between finals this week, I've managed to get this working in the patchset at http://www.FreeBSD.org/~jhb/patches/alpha.usb.patch. I'd like to commit this relatively soon (day or two) to -current, so please test this out.
