I believe DPDK's libeal uses /proc/pagemap to look up the physical address of large page mappings. Assuming you want to do the same thing, there is the MEM_EXTRACT_PADDR /dev/mem ioctl. It was added specifically for DPDK. See the mem(4) man page for details on its usage. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
