Userspace I/O drivers

modulename: uio.ko

configname: CONFIG_UIO

Linux Kernel Configuration
└─>Device Drivers

In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
Enable this to allow the userspace driver core code to be
built. This code allows userspace programs easy access to
kernel interrupts and memory locations, allowing some drivers
to be written in userspace. Note that a small kernel driver
is also required for interrupt handling to work properly.

If you don't know what to do here, say N.
