If I understand these structs correctly, they don't reside in memory,

Hi,
You could use the config capability if you wanted
to, though that multiplies the cost of each access
by a factor of ~4.
We are moving to 32bit drivers _anyway_, some of our drivers run in
32bit mode already, and with SMM mode landing in kvm now we have a
reliable way to transition to

virtio version 1.0 registers can (and actually do in the qemu
implementation) live in mmio space. So we must run the blk and
scsi virtio drivers in 32bit mode, otherwise we can't access them.
This also allows to drop a bunch of GET_LOWFLAT calls from the virtio
code in the following patches.

Add a parameter to pci_find_capability, to specify the start point.
This allows to find multiple capabilities of the same type, by calling
pci_find_capability again with the offset of the last capability found.

Hi,
It sounds like this patch is in preparation for some other patches.
It would help to see those other patches as well.
Yes. Still coding though ...
