1=====================2Firmware search paths3=====================4 5The following search paths are used to look for firmware on your6root filesystem.7 8* fw_path_para - module parameter - default is empty so this is ignored9* /lib/firmware/updates/UTS_RELEASE/10* /lib/firmware/updates/11* /lib/firmware/UTS_RELEASE/12* /lib/firmware/13 14The module parameter ''path'' can be passed to the firmware_class module15to activate the first optional custom fw_path_para. The custom path can16only be up to 256 characters long. The kernel parameter passed would be:17 18* 'firmware_class.path=$CUSTOMIZED_PATH'19 20There is an alternative to customize the path at run time after bootup, you21can use the file:22 23* /sys/module/firmware_class/parameters/path24 25You would echo into it your custom path and firmware requested will be searched26for there first. Be aware that newline characters will be taken into account27and may not produce the intended effects. For instance you might want to use:28 29echo -n /path/to/script > /sys/module/firmware_class/parameters/path30 31to ensure that your script is being used.32
