| 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. |

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

| 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. |
