  1. =====================
  2. Firmware search paths
  3. =====================
  4. The following search paths are used to look for firmware on your
  5. root filesystem.
  6. * fw_path_para - module parameter - default is empty so this is ignored
  7. * /lib/firmware/updates/UTS_RELEASE/
  8. * /lib/firmware/updates/
  9. * /lib/firmware/UTS_RELEASE/
  10. * /lib/firmware/
  11. The module parameter ''path'' can be passed to the firmware_class module
  12. to activate the first optional custom fw_path_para. The custom path can
  13. only be up to 256 characters long. The kernel parameter passed would be:
  14. * 'firmware_class.path=$CUSTOMIZED_PATH'
  15. There is an alternative to customize the path at run time after bootup, you
  16. can use the file:
  17. * /sys/module/firmware_class/parameters/path
  18. You would echo into it your custom path and firmware requested will be
  19. searched for there first.
