Some powernv systems include a hwrng. Guests can access it via the H_RANDOM hcall.Is there any reason to do this in the kernel?It's less code, and it's faster :)quoted
It does not have to be a particularly fast path;Sure, but do we have to make it slow on purpose?
We do not put non performance critical devices into the kernel. -- Gleb.
