The way mmio endianness is currently implemented is horrifying.
In the real world, CPUs have an endianness and write out data
to the memory bus. Instead of RAM, a receiving side here can be
a device. This device gets a byte stream again and needs to
make sense of it.

The way we're currently modeling mmio is too simplified. We assume that

Anthony sent out a patch to make backing filenames that contain a protocol

makes it impossible to distinguish between filenames that start with "file:"
and those that have no ":" at all.
This patch series solves the iss
The bdrv_find_protocol() function returns NULL if an unknown protocol
name is given. It returns the "file" protocol when the filename

Filenames may start with ":" to explicitly use a protocol like
nbd. Filenames with unknown protocols are rejected in most of QEMU

can be created, QEMU cannot use it since all the other relevant
functions reject such paths. Ma

The only reason we have bswap versions of the pci host code is that
