## NAME

**athdebug** - control the debug output from the madwifi device subsystem

## SYNOPSIS

**athdebug** \[-i device\] +/- bitmap

## DESCRIPTION

Set and clear debug bitmaps for the madwifi ath device subsystem. Each argument is a bitmap or its alias. If a bitmap alias is used then it must be prefixed by  either "-" to clear or "+" to set the corresponding bitmap.

All debugging output can be enabled with the 0xffffffff bitmap, while 0x0 disables all debug output.

- **-i device**

  The madwifi device to apply the settings to. If no interface is specified,  **athdebug** defaults to wifi0.

- **+/- bitmap**

  Set (+) or clear (-) a debug flag.

## BITMAP ALIASES

**xmit** - transmit of packets, just before they go out to the HW\
 **xmit\_desc** - transmit descriptors\
 **recv** - received packets, directly from the HW\
 **recv\_desc** - recv descriptors\
 **rate** - rate control modules\
 **reset** - reset processing and inititalization\
 **mode** - mode initialization and changes\
 **beacon** - beacon handling\
 **watchdog** - watchdog timeout\
 **intr** - interrupt processing\
 **xmit\_proc** - processing of transmit descriptors\
 **recv\_proc** - processing of receive descriptors\
 **beacon\_proc** - beacon processing\
 **calibrate** - periodic re-calibration\
 **keycache** - key cache management\
 **state** - 802.11 state transitions\
 **node** - node management **ff** - fast frame handling\
 **fatal** fatal errors\

## EXAMPLES

- **athdebug -i wifi1 0xffffffff**

  Enable all debug bitmaps on wifi1.

- **athdebug +rate**

  Enable rate debug bitmap on wifi0.

- **athdebug -rate**
