1 rfkill - radio frequency (RF) connector kill switch support 2 3 For details to this subsystem look at Documentation/driver-api/rfkill.rst. 4 5 For the deprecated ``/sys/class/rfkill/*/claim`` knobs of this interface look in 6 Documentation/ABI/removed/sysfs-class-rfkill. 7 8 What: /sys/class/rfkill 9 Date: 09-Jul-2007 10 KernelVersion: v2.6.22 11 Contact: linux-wireless@vger.kernel.org, 12 Description: The rfkill class subsystem folder. 13 Each registered rfkill driver is represented by an rfkillX 14 subfolder (X being an integer >= 0). 15 16 17 What: /sys/class/rfkill/rfkill[0-9]+/name 18 Date: 09-Jul-2007 19 KernelVersion v2.6.22 20 Contact: linux-wireless@vger.kernel.org 21 Description: Name assigned by driver to this key (interface or driver name). 22 Values: arbitrary string. 23 24 25 What: /sys/class/rfkill/rfkill[0-9]+/type 26 Date: 09-Jul-2007 27 KernelVersion v2.6.22 28 Contact: linux-wireless@vger.kernel.org 29 Description: Driver type string ("wlan", "bluetooth", etc). 30 Values: See include/linux/rfkill.h. 31 32 33 What: /sys/class/rfkill/rfkill[0-9]+/persistent 34 Date: 09-Jul-2007 35 KernelVersion v2.6.22 36 Contact: linux-wireless@vger.kernel.org 37 Description: Whether the soft blocked state is initialised from non-volatile 38 storage at startup. 39 Values: A numeric value: 40 41 - 0: false 42 - 1: true 43 44 45 What: /sys/class/rfkill/rfkill[0-9]+/state 46 Date: 09-Jul-2007 47 KernelVersion v2.6.22 48 Contact: linux-wireless@vger.kernel.org 49 Description: Current state of the transmitter. 50 This file was scheduled to be removed in 2014, but due to its 51 large number of users it will be sticking around for a bit 52 longer. Despite it being marked as stable, the newer "hard" and 53 "soft" interfaces should be preferred, since it is not possible 54 to express the 'soft and hard block' state of the rfkill driver 55 through this interface. There will likely be another attempt to 56 remove it in the future. 57 Values: A numeric value. 58 59 0: RFKILL_STATE_SOFT_BLOCKED 60 transmitter is turned off by software 61 1: RFKILL_STATE_UNBLOCKED 62 transmitter is (potentially) active 63 2: RFKILL_STATE_HARD_BLOCKED 64 transmitter is forced off by something outside of 65 the driver's control. 66 67 68 What: /sys/class/rfkill/rfkill[0-9]+/hard 69 Date: 12-March-2010 70 KernelVersion v2.6.34 71 Contact: linux-wireless@vger.kernel.org 72 Description: Current hardblock state. This file is read only. 73 Values: A numeric value. 74 75 0: inactive 76 The transmitter is (potentially) active. 77 1: active 78 The transmitter is forced off by something outside of 79 the driver's control. 80 81 82 What: /sys/class/rfkill/rfkill[0-9]+/soft 83 Date: 12-March-2010 84 KernelVersion v2.6.34 85 Contact: linux-wireless@vger.kernel.org 86 Description: Current softblock state. This file is read and write. 87 Values: A numeric value. 88 89 0: inactive 90 The transmitter is (potentially) active. 91 92 1: active 93 The transmitter is turned off by software. 94
