If guests can have different endianness (reasonable on some CPUs where it's switchable - some even have more than 2 options), then I guess the *host* on those systems have different endianness too. Is the host's endianness signalled to the guest anywhere, so that guest drivers can do cpu_to_qemuhost32(), when someone eventually finds that necessary? -- Jamie -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
