- Say Y if you want the Plug and Play Layer to print debug messages.
- This is useful if you are developing a PnP driver or troubleshooting.
+ 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.
