    Keeping device functionality inside device controller rather than OS kernel.

    A friend of mine asked me this question in the class and I could not answer it. He asked:

    Since we know kernel controls the physical hardware via device drivers. What if all this functionality is kept inside the device controller itself rather than kernel managing them. What would be the consequences of such scenario? Good or Bad?

    I searched online for this question but could not get information about this scenario. May be I'm not googling in the right keyword.

    You insight into this will help me getting clearing my concepts.

    Please answer.

    Thanks.

    Perhaps, because your googling seems to consist of finding places to post your question on.

    If at first you don't succeed, try writing your phone number on the exam paper.

    LOL it was actually fun to follow the links and read the answers. The treat was to see a post about Commodore C64 and its floppy drive VC1541 on a nowadays discussion list.
