[Qemu-devel] virtio_mmio address mapping

[Dean]

hi,all,

I am writing a UIO linux driver for a virtio_mmio device and find out that all 
those virtio_mmio devices' registers are arrange in one single 4K aligned page.
which makes writing an UIO driver hard since linux doesn't allow UIO driver to 
map a register space smaller than page size.
would you consider divide them into defferent pages?

what I am talking about is devices like:
a003000.virtio_mmio
a003c00.virtio_mmio
a003e00.virtio_mmio

what I am dealing with is a003e00.virtio_mmio
