Most of the code resides in kern_poll.c, plus device driver modifications to individual drivers to add the *_poll() handler, plus mostly one-line changes to a bunch of other files (listed at the end of this message) to define constants or call the appropriate functions. A device_poll(4) manpage is still missing. It should contain an explaination of what DEVICE_POLLING does, which you can find at http://info.iet.unipi.it/~luigi/polling/ To use this facility: add options DEVICE_POLLING to your kernel config file, and at runtime do sysctl kern.polling.enable=1 At the moment only the "dc", "fxp" and "sis" drivers have been modified to make use of this feature. More drivers will be modified as i have a chance to test them (patches welcome, look at the changes in the above drivers).
