| 75 | When these files are more recent than the kernel, the kernel |
| 76 | will handle the functionality it supports and may report errors |

| 119 | human-readable form instead of just 32-bit hex dumps. This is useful |
| 120 | if you are trying to debug IPC with the DSP firmware. |

| 127 | elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that |
| 128 | with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM. |
| 129 | On platforms (e.g. Intel SKL-) where position update IPC is the only |
| 130 | one choice, this setting won't impact anything. |

| 138 | This option enables caching of debugfs |
| 139 | memory -> DSP resource (memory, register, etc) |
| 140 | before the audio DSP is suspended. This will increase the suspend |
| 141 | latency and therefore should be used for debug purposes only. |
