config IWLWIFI_LEGACY_DEVICE_TRACING

	bool "iwlwifilegacy legacy device access tracing"

	depends on IWLWIFI_LEGACY

	depends on EVENT_TRACING

	help

	  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.
