As the patch notes, Apple's M4 has the SME register & instructions, plus Streaming SVE Mode and the SVE register set, but most of the SVE instructions are not supported. And the SVE registers (z0-31, p0-15) are only available when the core is in Streaming SVE Mode I believe.  I guess the main concern would be someone keying off of "this core has SVE registers" (true) and "this core can run SVE API tests" (most likely false).

But as far as the patch goes, it looks good to me.  While Docker might not virtualize the SME, the Darwin kernel does support this and Linux running in a VM will have access to these hardware resources on an M4 system.
