/proc/sys/abi/sve_default_vector_length wants a vector length in
bytes, and it looks like we take a length in bits. I assume that's
to match other places where the user can specify vector lengths,
but we should mention the units we expect and that it's not what
the kernel uses.
Oops, that wasn't intentional.
We also don't support the kernel's (undocumented) "-1 means set
to the maximum" behaviour -- do we need it, or is that more reasonably
achievable by the user via other properties ?
I didn't notice that one either, possibly because it's undocumented. Might as well
support that too.
