1 ===================== 2 Firmware search paths 3 ===================== 4 5 The following search paths are used to look for firmware on your 6 root filesystem. 7 8 * fw_path_para - module parameter - default is empty so this is ignored 9 * /lib/firmware/updates/UTS_RELEASE/ 10 * /lib/firmware/updates/ 11 * /lib/firmware/UTS_RELEASE/ 12 * /lib/firmware/ 13 14 The module parameter ''path'' can be passed to the firmware_class module 15 to activate the first optional custom fw_path_para. The custom path can 16 only be up to 256 characters long. The kernel parameter passed would be: 17 18 * 'firmware_class.path=$CUSTOMIZED_PATH' 19 20 There is an alternative to customize the path at run time after bootup, you 21 can use the file: 22 23 * /sys/module/firmware_class/parameters/path 24 25 You would echo into it your custom path and firmware requested will be searched 26 for there first. Be aware that newline characters will be taken into account 27 and may not produce the intended effects. For instance you might want to use: 28 29 echo -n /path/to/script > /sys/module/firmware_class/parameters/path 30 31 to ensure that your script is being used.
