Intel released a documentation set for MIC, which does not even contain
any references to the startup sequence and system management. The only
thing which is provided is patch for Linux kernel.
I will be very delighted and want to appear completely wrong, but my
suspect is that FreeBSD will be in the same position with MIC as it is
with Intel GPUs. I asked Intel representative about MIC programming
documentation some time ago, the answer was 'we do provide extensive
documentation for SDK'. After I noted that this is not what is needed
to support the hardware on !Linux, I only get a blank eye.
