400 SVE User-mode Default Vector Length Property
403 For qemu-aarch64, the cpu property ``sve-default-vector-length=N`` is
405 ``/proc/sys/abi/sve_default_vector_length``.  The default length, ``N``,
407 If not specified, the default vector length is 64.
409 If the default length is larger than the maximum vector length enabled,

436 For qemu-aarch64, the cpu property ``sme-default-vector-length=N`` is
