+/* sercos3: UIO driver for the Automata Sercos III PCI card
+
+   Copyright (C) 2008 Linutronix GmbH
+     Author: John Ogness <john.ogness@linutronix.de>
+
+   This is a straight-forward UIO driver, where interrupts are disabled
+   by the interrupt handler and re-enabled via a write to the UIO device
+   by the userspace-part.
+
+   The only part that may seem odd is the use of a logical OR when
+   storing and restoring enabled interrupts. This is done because the
+   userspace-part could directly modify the Interrupt Enable Register
+   at any time. To reduce possible conflicts, the kernel driver uses
+   a logical OR to make more controlled changes (rather than blindly
+   overwriting previous values).
+
+   Race conditions exist if the userspace-part directly modifies the
+   Interrupt Enable Register while in operation. The consequences are
+   that certain interrupts would fail to be enabled or disabled. For
+   this reason, the userspace-part should only directly modify the
+   Interrupt Enable Register at the beginning (to get things going).
+   The userspace-part can safely disable interrupts at any time using
+   a write to the UIO device.

+          Compiles debug level messages into the kernel, which would not
+          otherwise be available at runtime. These messages can then be
+          enabled/disabled on a per module basis. This mechanism implicitly
+          enables all pr_debug() and dev_dbg() calls. The impact of this
+          compile option is a larger kernel text size of about 2%.
+
+          Usage:
+
+          Dynamic debugging is controlled by the debugfs file,
+          dynamic_printk/modules. This file contains a list of the modules that
+          can be enabled. The format of the file is the module name, followed
+          by a set of flags that can be enabled. The first flag is always the
+          'enabled' flag. For example:
+
+                <module_name> <enabled=0/1>
+                                .

+                                .
+
+          <module_name> : Name of the module in which the debug call resides
+          <enabled=0/1> : whether the messages are enabled or not
+
+          From a live system:
+
+                snd_hda_intel enabled=0
+                fixup enabled=0
+                driver enabled=0
+
+          Enable a module:

+
+                $echo "set enabled=0 <module_name>" > dynamic_printk/modules
+

+                $echo "set enabled=1 all" > dynamic_printk/modules
+
+          Disable all modules:
+
+                $echo "set enabled=0 all" > dynamic_printk/modules
+
+          Finally, passing "dynamic_printk" at the command line enables

+          disable command.
