- * ice_cfg_fw_log - configure FW logging
- * @hw: pointer to the HW struct

- *
- * 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.
