What: /sys/bus/vmbus/devices/.../driver_override

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 uio_hv_generic > 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.
