Let's ask them! 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. --qKjsupNRLbaULa5O Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iEYEARECAAYFAk/hl04ACgkQC3+MBN1Mb4iCGACfauJDOa/A8vS8RDWB+yjYVgZa lO8An0L/vEGPYjix1K4W56ExS/TZa2Hm =I/GG -----END PGP SIGNATURE----- --qKjsupNRLbaULa5O--
