rfkill - RF kill switch support — The Linux Kernel ...

    https://www.kernel.org/doc/html/latest/driver-api/rfkill.html
    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’.

    Jun 16, 2014 · RF switches are used in many Wifi and Bluetooth cards (RF switch subsystem support). The “RF” stands for Radio Frequency. RF switches route high-frequency signals. Input support for RF switches also exists in the kernel (RF switch input support). The kernel can control and query radio transmitters (Generic rfkill regulator driver).

    Some devices come with a hard switch that lets you kill different types of RF radios: 802.11 / Bluetooth / NFC / UWB / WAN / WIMAX / FM. Some times these buttons may kill more than one RF type. The Linux kernel rfkill subsystem exposes these hardware buttons and lets userspace query its status and set its status through a /dev/rfkill.
