It creates or + removes device node files in the /dev directory, or it + renames network interfaces. + + Usually udev runs as udevd(8) and receives uevents directly + from the kernel if a device is added or removed form the system. + + If udev receives a device event, it matches its configured + rules against the available device attributes provided in + sysfs to identify the device. Rules that match, may provide + additional device information or specify a device node name + and multiple symlink names and instruct udev to run + additional programs as part of the device event handling. config UDEV_UDEVD bool "udevd" depends on UDEV + help + udevd listens to kernel uevents and passes the incoming + events to udev. It ensures the right event order and + takes care, that events for child devices are delayed + until the parent has finished the device handling. config UDEV_INFO bool "udevinfo" depends on UDEV + help + udevinfo queries the udev database for device + information stored in the udev database. It + can also query the properties of a device from + its sysfs representation to help creating udev + rules that match this device. config UDEV_SEND bool "udevsend" depends on UDEV + help + FIXME: This item needs to be documented config UDEV_START bool "udevstart" depends on UDEV + help + FIXME: This item needs to be documented config UDEV_TEST bool "udevtest" depends on UDEV + help + udevtest simulates a udev run for the given device + and prints out the name of the node udev would have + created, or the name of the network interface, that + would have been renamend. config UDEV_FW_HELPER bool "firmware helper" depends on UDEV + help + FIXME: This item needs to be documented |
