479 * ice_cfg_fw_log - configure FW logging
480 * @hw: pointer to the hw struct
481 * @enable: enable certain FW logging events if true, disable all if false
482 *
483 * This function enables/disables the FW logging via Rx CQ events and a UART
484 * port based on predetermined configurations. FW logging via the Rx CQ can be
485 * enabled/disabled for individual PF's. However, FW logging via the UART can
486 * only be enabled/disabled for all PFs on the same device.
487 *
488 * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
489 * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
490 * before initializing the device.
491 *
492 * When re/configuring FW logging, callers need to update the "cfg" elements of
493 * the hw->fw_log.evnts array with the desired logging event configurations for
494 * modules of interest. When disabling FW logging completely, the callers can
495 * just pass false in the "enable" parameter. On completion, the function will
496 * update the "cur" element of the hw->fw_log.evnts array with the resulting
497 * logging event configurations of the modules that are being re/configured. FW
498 * logging modules that are not part of a reconfiguration operation retain their
499 * previous states.
500 *
501 * Before resetting the device, it is recommended that the driver disables FW
502 * logging before shutting down the control queue. When disabling FW logging
503 * ("enable" = false), the latest configurations of FW logging events stored in
504 * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
505 * a device reset.
506 *
507 * When enabling FW logging to emit log messages via the Rx CQ during the
508 * device's initialization phase, a mechanism alternative to interrupt handlers
509 * needs to be used to extract FW log messages from the Rx CQ periodically and
510 * to prevent the Rx CQ from being full and stalling other types of control
511 * messages from FW to SW. Interrupts are typically disabled during the device's
512 * initialization phase.
