| * 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. |
