From beafc54c4e2fba24e1ca45cdb7f79d9aa83e3db1 Mon Sep 17 00:00:00 2001 From: "Hans J. Koch" Date: Thu, 7 Dec 2006 10:58:29 +0100 Subject: UIO: Add the User IO core code This interface allows the ability to write the majority of a driver in userspace with only a very small shell of a driver in the kernel itself. It uses a char device and sysfs to interact with a userspace process to process interrupts and control memory accesses. See the docbook documentation for more details on how to use this interface.
