The s390x firmware in question, is built from source, on Ubuntu, on every src:qemu upload on the s390x architecture and shipped in an arch:s390x package. qemu-system-s390x requires to run on the s390x hardware, as it is effectively passthrough kvm only, and is not userspace emulated. (Does not work on non-s390x machines). Therefore src:qemu should build s390x specific firmware and ship in arch:s390x package as if it is an s390x-specific binary. Stuff about arch:all autobilders etc do not in practice cause any constraints here since this particular firmware is useless in a non _s390x.deb. There are no plans to make qemu-system-s390x able to perform userspace emulation on non-s390x architectures. -- Regards, Dimitri.
