The hw-restart crash inject mode is a special mode, where there is no crash generated in the firmware, but instead the driver restarts the firmware. In order to restart WCN3990 firmware, the driver needs to send qmi_wlan_disable message followed by the qmi_wlan_enable message to the WCN3990 firmware. Currently the qmi_wlan_disable message is not sent to the WCN3990 firmware when hw-restart crash is injected, which causes the firmware to crash when the driver sends qmi_wlan_enable message during ath10k_restart. Send qmi_wlan_disable to the WCN3990 firmware when the hw-restart crash is injected via debugfs.

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.
