I guess someone could implement a sysctl API to access PCI BAR registers, rather than mapping /dev/pci or however pciconf -r works. That way you'd implement it once and all devices would have their BAR registers show up in a userland-friendly way. 2c, Adrian _______________________________________________ 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"
