===================== 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.
