No, FreeBSD doesn't currently do what this decribes yet. It would be possible to do it by adding a new device_pause() method that drivers would be required to implement while the resources were shuffled around though and possibly a device_unpause() method so that they could update their state if their resources were changed while the device was paused. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
