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