| Firmware search paths |
| ===================== |
| |
| The following search paths are used to look for firmware on your |
| root filesystem. |
| |
| * fw_path_para - module parameter - default is empty so this is ignored |
| * /lib/firmware/updates/UTS_RELEASE/ |
| * /lib/firmware/updates/ |
| * /lib/firmware/UTS_RELEASE/ |
| * /lib/firmware/ |
| |
| The module parameter ''path'' can be passed to the firmware_class module |
| to activate the first optional custom fw_path_para. The custom path can |
| only be up to 256 characters long. The kernel parameter passed would be: |
| |
| * 'firmware_class.path=$CUSTOMIZED_PATH' |
| |
| There is an alternative to customize the path at run time after bootup, you |
| can use the file: |
| |
| * /sys/module/firmware_class/parameters/path |
| |
| You would echo into it your custom path and firmware requested will be searched |
| for there first. Be aware that newline characters will be taken into account |
| and may not produce the intended effects. For instance you might want to use: |
| |
| echo -n /path/to/script > /sys/module/firmware_class/parameters/path |
| |
| to ensure that your script is being used. |
