21The rfkill subsystem has a concept of "hard" and "soft" block, which
22differ little in their meaning (block == transmitters off) but rather in
23whether they can be changed or not:

32optionally, letting the system know about hardware-disabled states that may
33be implemented on the device. This code is enabled with the CONFIG_RFKILL
34Kconfig option, which drivers can "select".
35
36The rfkill class code also notifies userspace of state changes, this is
37achieved via uevents. It also provides some sysfs files for userspace to
38check the status of radio transmitters. See the "Userspace support" section

108The following sysfs entries exist for every rfkill device: 87The recommended userspace interface to use is /dev/rfkill, which is a misc
88character device that allows userspace to obtain and set the state of rfkill
89devices and sets of devices. It also notifies userspace about device addition
90and removal. The API is a simple read/write API that is defined in
91linux/rfkill.h, with one ioctl that allows turning off the deprecated input
92handler in the kernel for the transition period.
93
94Except for the one ioctl, communication with the kernel is done via read()
95and write() of instances of 'struct rfkill_event'. In this structure, the
96soft and hard block are properly separated (unlike sysfs, see below) and
97userspace is able to get a consistent snapshot of all rfkill devices in the
98system. Also, it is possible to switch all rfkill drivers (or all drivers of
99a specified type) into a state which also updates the default state for
100hotplugged devices.
101
102After an application opens /dev/rfkill, it can read the current state of
103all devices, and afterwards can poll the descriptor for hotplug or state
104change events.

106Applications must ignore operations (the "op" field) they do not handle,
