In general, I figured out the magic dance that is required to enable multiqueue support for em(4). Jeffery's comment about disabling MSI-X was what I was looking for. I've added a review to enable things as a kernel compile option here: https://reviews.freebsd.org/D1994 If the EM_MULTIQUEUE option is enabled, MSI-X defaults to off. This is for testing and needs to be resolved. Perfect for current. EM_MULTIQUEUE is off by default. I've also added missing tuneables to the man page in this review. So, this is a cleanup to being a dev push from my side. Expect more to come in this space. sean -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQF8BAEBCgBmBQJU852ZXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRCQUFENDYzMkU3MTIxREU4RDIwOTk3REQx MjAxRUZDQTFFNzI3RTY0AAoJEBIB78oecn5k0agIAJlkdyqr8N5tALP7c8Eafwg8 w/cFkhcuLwQoCxMQ1gNJpNTKnGWixSalgQTfKdiBvYKGFHtBA5edW32hQSBkus3W yU0RLEdEJyz9F0fMGuxGC1EQRSt54um0B/Ctd7vHEdJtgr+N8ssMsaZVTPioOuEH zXtAId/Gv85UvWH5iElvEph2pEofMw2BQ0XsNUgWwVj5DoAo886reTrsBwqpETjp yqUNxTAtuvS7cK/843nPmpWItg4eYw2YONFOZRVL5CQXFViRHwjf9iSQHelzbcYU suy5Lu5m50ZPGCLgIt8ciWReovDbNkQqSgwc3HbeZ2JRcDMN/Km+nJFeI8eV3+Q= =IbSV -----END PGP SIGNATURE----- _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
