Re: What do people think about adaptive polling?

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:It's a good idea but i think that it could be improved:
:
:For devices with working interrupts if a device starts generating
:too many interrupts, just switch to polling mode.
:
:This would be very useful for things like network cards which
:could switch from interrupt to polling mode on the fly and get
:better performance with higher load.

    It's hard to how many is too many, but this would certainly be a benefit
    to older network cards which do not have interrupt moderation.

    The parallel port comes to mind, though.
