Hmm, this is good for specific drivers, but for a generic one like qemu, still need sysfs to figure out the size at least, and we need config accesses which uio does not support now. And if you use libpci as qemu does now, this interface will likely go unused. So .. there does not seem to be much point at the moment. My idea is, let's start with a minimal interface, longer term let's see if we can add config access, mmap and other stuff like eventfd.
