Plug and Play (PnP) is a standard for peripherals which allows those
peripherals to be configured by software, e.g. assign IRQ's or other
parameters. No jumpers on the cards are needed, instead the values
are provided to the cards from the BIOS, from the operating system,
or using a user-space utility.
Say Y here if you would like Linux to configure your Plug and Play
devices. You should then also say Y to all of the protocols below.
Alternatively, you can say N here and configure your PnP devices
using user space utilities such as the isapnptools package.
If unsure, say Y.

bool "PNP debugging messages"
depends on PNP
help
Say Y here if you want the PNP layer to be able to produce debugging
messages if needed. The messages can be enabled at boot-time with
the pnp.debug kernel parameter.
This option allows you to save a bit of space if you do not want
the messages to even be built into the kernel.
If you have any doubts about this, say Y here.
