When hardware rfkill is enabled in the firmware it will report the capability via using WMI_TLV_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY event to the host. ath10k will check the capability, and if it is enabled then ath10k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When the firmware detects hardware rfkill is enabled by the user, it will report it via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath10k receives the event it will send wmi command WMI_PDEV_SET_PARAM to the firmware to enable/disable the radio and also notifies cfg80211. We can't power off the device when rfkill is enabled, as otherwise the firmware would not be able to detect GPIO changes and report them to the host. So when rfkill is enabled, we need to keep the firmware running. Tested with QCA6174 PCI with firmware WLAN.RM.4.4.1-00109-QCARMSWPZ-1.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
