* ice_cfg_fw_log - configure FW logging
* @hw: pointer to the HW struct
* @enable: enable certain FW logging events if true, disable all if false
*
* This function enables/disables the FW logging via Rx CQ events and a UART
* port based on predetermined configurations. FW logging via the Rx CQ can be
* enabled/disabled for individual PF's. However, FW logging via the UART can
* only be enabled/disabled for all PFs on the same device.
*
* To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
* hw->fw_log need to be set accordingly, e.g. based on user-provided input,
* before initializing the device.
*
* When re/configuring FW logging, callers need to update the "cfg" elements of
* the hw->fw_log.evnts array with the desired logging event configurations for
* modules of interest. When disabling FW logging completely, the callers can
* just pass false in the "enable" parameter. On completion, the function will
* update the "cur" element of the hw->fw_log.evnts array with the resulting
* logging event configurations of the modules that are being re/configured. FW
* logging modules that are not part of a reconfiguration operation retain their
* previous states.
*
* Before resetting the device, it is recommended that the driver disables FW
* logging before shutting down the control queue. When disabling FW logging
* ("enable" = false), the latest configurations of FW logging events stored in
* hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
* a device reset.
*
* When enabling FW logging to emit log messages via the Rx CQ during the
* device's initialization phase, a mechanism alternative to interrupt handlers
* needs to be used to extract FW log messages from the Rx CQ periodically and
* to prevent the Rx CQ from being full and stalling other types of control
* messages from FW to SW. Interrupts are typically disabled during the device's
* initialization phase.
