  4. Description:
  5. This file allows the driver for a device to be specified which
  6. will override standard static and dynamic ID matching. When
  7. specified, only a driver with a name matching the value written
  8. to driver_override will have an opportunity to bind to the
  9. device. The override is specified by writing a string to the
  10. driver_override file (echo uio_hv_generic > driver_override) and
  11. may be cleared with an empty string (echo > driver_override).
  12. This returns the device to standard matching rules binding.
  13. Writing to driver_override does not automatically unbind the
  14. device from its current driver or make any attempt to
  15. automatically load the specified driver. If no driver with a
  16. matching name is currently loaded in the kernel, the device
  17. will not bind to any driver. This also allows devices to
  18. opt-out of driver binding using a driver_override name such as
  19. "none". Only a single driver may be specified in the override,
  20. there is no support for parsing delimiters.
