	  Provide a logging backend which writes to a buffer and

	help
	  Sets the ring buffer size cAVS HDA uses for logging. Effectively
	  determines how many log messages may be written to in a period of time.
	  The period of time is decided by how often to inform the hardware of
	  writes to the buffer.

	default 500
	help
	    The Intel ADSP HDA backend periodically writes out its buffer contents
	    to hardware by informing the DMA hardware the contents of the ring
	    buffer.

config LOG_BACKEND_ADSP_HDA_CAVSTOOL
	bool "Log backend is to be used with cavstool"
	help
		Use cavstool understood IPC messages to inform setup and logging of
		HDA messages.

config LOG_BACKEND_ADSP_HDA_PADDING
	bool "Log backend should pad the buffer with \0 characters when flushing"
	help
		HDA requires transfers be 128 byte aligned such that a partial message may
		never make it across unless padded with \0 characters to the next 128 byte
		aligned address. This may or may not work depending on the log format
		being used but should certainly work with text based logging.
