Thanks for the suggestion!
_ctypes.windll.kernel32.IsProcessorFeaturePresent(PF_ARM_SVE_INSTRUCTIONS_AVAILABLE)_
returns _1_ if the underlying hardware supports SVE and _0_ otherwise. That
said, it looks like the runner used to execute commands on the active platform
cannot parse the command line correctly. Using the runner to execute the
command ensures that it's executed locally or remotely as appropriate.
Nevertheless, I think that a native probe executable built on the fly and run
through the runner would be a stronger alternative to both the PowerShell chain
and _ctypes_. What do you think?
