@@ -19,82 +18,62 @@ disable all transmitters of a certain type (or all). This is intended for
situations where transmitters need to be turned off, for example on
aircraft.
+The rfkill subsystem has a concept of "hard" and "soft" block, which
+differ little in their meaning (block == transmitters off) but rather in
+whether they can be changed or not:
+ - hard block: read-only radio block that cannot be overriden by software
+ - soft block: writable radio block (need not be readable) that is set by
+ the system software.
2. Implementation details
-The rfkill subsystem is composed of various components: the rfkill class, the
-rfkill-input module (an input layer handler), and some specific input layer
-events.
-
-The rfkill class is provided for kernel drivers to register their radio
-transmitter with the kernel, provide methods for turning it on and off and,
-optionally, letting the system know about hardware-disabled states that may
-be implemented on the device. This code is enabled with the CONFIG_RFKILL
-Kconfig option, which drivers can "select".
-
-The rfkill class code also notifies userspace of state changes, this is
-achieved via uevents. It also provides some sysfs files for userspace to
-check the status of radio transmitters. See the "Userspace support" section
-below.
+The rfkill subsystem is composed of three main components:
+ * the rfkill core,
+ * the deprecated rfkill-input module (an input layer handler, being
+ replaced by userspace policy code) and
+ * the rfkill drivers.
+The rfkill core provides API for kernel drivers to register their radio
+transmitter with the kernel, methods for turning it on and off and, letting
+the system know about hardware-disabled states that may be implemented on
+the device.
-The rfkill-input code implements a basic response to rfkill buttons -- it
-implements turning on/off all devices of a certain class (or all).
+The rfkill core code also notifies userspace of state changes, and provides
+ways for userspace to query the current states. See the "Userspace support"
+section below.
When the device is hard-blocked (either by a call to rfkill_set_hw_state()
-or from query_hw_block) set_block() will be invoked but drivers can well
-ignore the method call since they can use the return value of the function
-rfkill_set_hw_state() to sync the software state instead of keeping track
-of calls to set_block().
-
-
-The entire functionality is spread over more than one subsystem:
-
- * The kernel input layer generates KEY_WWAN, KEY_WLAN etc. and
- SW_RFKILL_ALL -- when the user presses a button. Drivers for radio
- transmitters generally do not register to the input layer, unless the
- device really provides an input device (i.e. a button that has no
- effect other than generating a button press event)
-
- * The rfkill-input code hooks up to these events and switches the soft-block
- of the various radio transmitters, depending on the button type.
-
- * The rfkill drivers turn off/on their transmitters as requested.
-
- * The rfkill class will generate userspace notifications (uevents) to tell
- userspace what the current state is.
+or from query_hw_block) set_block() will be invoked for additional software
+block, but drivers can ignore the method call since they can use the return
+value of the function rfkill_set_hw_state() to sync the software state
+instead of keeping track of calls to set_block(). In fact, drivers should
+use the return value of rfkill_set_hw_state() unless the hardware actually
+keeps track of soft and hard block separately.
+3. Kernel API
-3. Kernel driver guidelines
-
-Drivers for radio transmitters normally implement only the rfkill class.
-These drivers may not unblock the transmitter based on own decisions, they
-should act on information provided by the rfkill class only.
+Drivers for radio transmitters normally implement an rfkill driver.
Platform drivers might implement input devices if the rfkill button is just
that, a button. If that button influences the hardware then you need to
-implement an rfkill class instead. This also applies if the platform provides
+implement an rfkill driver instead. This also applies if the platform provides
a way to turn on/off the transmitter(s).
-During suspend/hibernation, transmitters should only be left enabled when
-wake-on wlan or similar functionality requires it and the device wasn't
-blocked before suspend/hibernate. Note that it may be necessary to update
-the rfkill subsystem's idea of what the current state is at resume time if
-the state may have changed over suspend.
-
+For some platforms, it is possible that the hardware state changes during
+suspend/hibernation, in which case it will be necessary to update the rfkill
+core with the current state is at resume time.
+To create an rfkill driver, driver's Kconfig needs to have

5. Userspace support
-The following sysfs entries exist for every rfkill device:
+The recommended userspace interface to use is /dev/rfkill, which is a misc
+character device that allows userspace to obtain and set the state of rfkill
+devices and sets of devices. It also notifies userspace about device addition
+and removal. The API is a simple read/write API that is defined in
+linux/rfkill.h, with one ioctl that allows turning off the deprecated input
+handler in the kernel for the transition period.
+
+Except for the one ioctl, communication with the kernel is done via read()
+and write() of instances of 'struct rfkill_event'. In this structure, the
+soft and hard block are properly separated (unlike sysfs, see below) and
+userspace is able to get a consistent snapshot of all rfkill devices in the
+system. Also, it is possible to switch all rfkill drivers (or all drivers of
+a specified type) into a state which also updates the default state for
+hotplugged devices.
+
+After an application opens /dev/rfkill, it can read the current state of
+all devices, and afterwards can poll the descriptor for hotplug or state
+change events.
+
+Applications must ignore operations (the "op" field) they do not handle,
+this allows the API to be extended in the future.
+
+Additionally, each rfkill device is registered in sysfs and there has the
+following attributes:
name: Name assigned by driver to this key (interface or driver name).
- type: Name of the key type ("wlan", "bluetooth", etc).
