There is not anything in stock FreeBSD that currently does zero-copy sockets for TCP. You could add such a thing, but you would have to implement your own. :( Some of the building blocks are in place. For example, you can create POSIX shared memory objects via shm_open() (and FreeBSD has an extension where a path of SHM_ANON creates anonymous, unnamed objects) and pass that fd into the kernel where an ioctl handler can map it into KVA using shm_map() and shm_unmap(). You'd have to change TCP to do something useful with this buffer however. -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
