This option will enable debug tracing output for the iwlwifilegacy drivers. This will result in the kernel module being ~100k larger. You can control which debug output is sent to the kernel log by setting the value in /sys/class/net/wlan0/device/debug_level This entry will only exist if this option is enabled. To set a value, simply echo an 8-byte hex value to the same file: % echo 0x43fff > /sys/class/net/wlan0/device/debug_level You can find the list of debug mask values in: drivers/net/wireless/iwlwifilegacy/iwl-debug.h If this is your first time using this driver, you should say Y here as the debug information can assist others in helping you resolve any problems you may encounter.
Enable creation of debugfs files for the iwlwifilegacy drivers. This is a low-impact option that allows getting insight into the driver's state at runtime.
Say Y here to trace all commands, including TX frames and IO accesses, sent to the device. If you say yes, iwlwifilegacy will register with the ftrace framework for event tracing and dump all this information to the ringbuffer, you may need to increase the ringbuffer size. See the ftrace documentation for more information. When tracing is not enabled, this option still has some (though rather small) overhead. If unsure, say Y so we can help you better when problems occur.
This option enables support for Select to build the driver supporting the: Intel Wireless WiFi Link 4965AGN This driver uses the kernel's mac80211 subsystem. In order to use this driver, you will need a microcode (uCode) image for it. You can obtain the microcode from: <http://intellinuxwireless.org/>. The microcode is typically installed in /lib/firmware. You can look in the hotplug script /etc/hotplug/firmware.agent to determine which directory FIRMWARE_DIR is set to when the script runs. If you want to compile the driver as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read <file:Documentation/kbuild/modules.txt>. The module will be called iwl4965.
