Description:
|
|
This file allows the driver for a device to be specified which
|
|
will override standard OF, ACPI, ID table, and name 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 vfio-amba > 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.
