The command to simulate firmware crash: echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash It will send WMI_FORCE_FW_HANG_ASSERT to firmware, then it will trigger CPU interrupt status register for SDIO chip, ath10k driver need to configure it while enable SDIO interrupt, otherwise ath10k driver will not get the assert error info. After this change, it will success for simulate firmware crash. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-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.
