I think you are wrong. Using a software buffer means you have to copy
data instead of mmap. Also 2 periods per buffer gives the lowest

the only reason to use more than 2 periods per buffer is if your system
can't reliably handle all of the interrupts in time.

jackd allows
any number of periods.
alsa allows any number of periods.
the HDSP and Hammerfall h/w only allows 2 periods, because it follows
the design of ASIO in its hardware/firmware design.
And I assume that jack purely deals with direct hardware buffers, right?
Wouldn't it be perhaps also nice to have software buffers as sometimes
machines can more easily deal with more periods of smaller buffers than less
periods with larger buffers (please correct me if I am wrong).
