Add debugfs interface "fw_dbglog_config" to configure firmware log level. Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID. Command to configure, echo "<dbglog_param> <values>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config where dbglog_param can be, 1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel 2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev here, <values> = vdev_id 3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev except ERROR logs here, <values> = vdev_id 4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap here, <values> = vdev_enable_bitmap 5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the modules specified in the module bitmap. Command to configure for this log param, $ echo "5 <values> <module_id_index> <is_end>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config here, <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel <module_id_index> = index of module bitmap. Max module id is 512. So, module_id_index is 0-15. <is_end> = to indicate if more configuration to follow. 6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable. Command to configure for this log param, $ echo "6 <values> <module_id_index> <is_end>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config here, <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel <module_id_index> = index of module bitmap. Max module id is 512. So, module_id_index is 0-15. <is_end> = to indicate if more configuration to follow.
