Hi Artyom,
Nice patchset!
Every PCI Slot in PBM has 4 directly mapped IRQ lines. Use the IRQ routing schema 0bssnn (Bus, Slot, interrupt Number) described in Section 19.3.3 of UltraSPARCâ„¢-IIi User's Manual.
Please note that this patch requires the QEMU counterpart patch.

Any reason why this invokes get_cur_dev() rather than just using dev as per the OLDWORLD/NEWWORLD calls?
