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.
Sample command usage,
To enable module WLAN_MODULE_WMI and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "1 0x10001" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
To enable module bit map from 32 to 63 and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "5 0xffffffff00000001 1 1" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
