+ This default value is used when the kernel is executing and
+ for any process that has not set the DSCR itself.
+ If a process ever sets the DSCR (via direct access to the
+ SPR) that value will be persisted for that process and used
+ on any CPU where it executes (overriding the value described
+ here).
+ If set by a process it will be inherited by child processes.

+Contact: Alex Williamson <alex.williamson@redhat.com>
+Description:
+ This file allows the driver for a device to be specified which
+ will override standard static and dynamic ID matching. When
+ specified, only a driver with a name matching the value written
+ to driver_override will have an opportunity to bind to the
+ device. The override is specified by writing a string to the
+ driver_override file (echo pci-stub > driver_override) and
+ may be cleared with an empty string (echo > driver_override).
+ This returns the device to standard matching rules binding.
+ Writing to driver_override does not automatically unbind the
+ device from its current driver or make any attempt to
+ automatically load the specified driver. If no driver with a
+ matching name is currently loaded in the kernel, the device
+ will not bind to any driver. This also allows devices to
+ opt-out of driver binding using a driver_override name such as
+ "none". Only a single driver may be specified in the override,
+ there is no support for parsing delimiters.
