Allocating an IRQ on PCI

Hi all, I want to allocate an IRQ for a PCI device driver. Normally this is easy enough, since the BIOS would reserve it for me, then I would just have to bus_alloc_resource and not even care which IRQ line it's using. Thing is, here the BIOS hasn't allocated an IRQ, so I'll need to

AMD PM driver finally there!

OK, I've finally got there with the AMD pm/smbus driver. It's now newbus, though this was quite a weird experience. In the end, I found that my BIOS wasn't giving out any I/O resource information for the AMD 756's power management function, hence bus_alloc_resource failed. A bus_set_resource

Allocating I/O port space

Hi again all, Well, despite the reception I'm still here, desperately trying to allocate an I/O port range! Still can't get bus_alloc_resource to work, despite doing everything by the book. I have a question. My kernel prints this: amdpm0: AMD 756 Power Management Controller at device 7.3 on
