I was under impression that OFED provides drivers for Mellanox. At least I am using OFED 1.2 for Mellanox Arbel InfiniHost III, and I was under impression that even ConnectX cards are supported by the 1.3.x as well. Particularily, the ofa_kernel component of OFED build provides core, HW and ULPs kernel modules. I think that OFED sources can be taken and ported (at least partially, for example, the driver parts) to provide kernel drivers for the cards. Am I missing something? --=20 Eygene _ ___ _.--. # \`.|\..----...-'` `-._.-'_.-'` # Remember that it is hard / ' ` , __.--' # to read the on-line manual =20 )/' _/ \ `-_, / # while single-stepping the kernel. `-'" `"\_ ,_.-;_.-\_ ', fsc/as # _.-'_./ {_.' ; / # -- FreeBSD Developers handbook=20 {_.-``-' {_/ # --o7gdRJTuwFmWapyH Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkjkg7kACgkQthUKNsbL7YjzyQCgqVkahYpepUmsY1kvXq1qFAhk BlcAn3/9GAYGIQP3KeOKb6/gEz0TFo47 =5VUC -----END PGP SIGNATURE----- --o7gdRJTuwFmWapyH--
