Does qemu mark the device has having a particular endianess then, or does it switch the layout of the framebuffer to match what the CPU does?The latter. On neither architecture does qemu expose this flag. The default endianess corresponds to the host.
"host" as in the machine that qemu runs on, or the machine that is
being emulated? I suppose it would be broken either way, but in the
latter case, we could get away with detecting that the machine is
running under qemu.
