| /** |
| * This collection of tests performs EDID and status injection tests. Injection |
| * forces a given EDID and status on a connector. The kernel will parse the |
| * forced EDID and we will check whether correct metadata is exposed to |
| * userspace. |
| * |
| * Currently, this can be used to test: |
| * |
| * - 4K modes exposed via KMS |
| * - Audio capabilities of the monitor exposed via ALSA. EDID-Like Data (ELD) |
| * entries in /proc/asound are verified. |
| * |
| * Injection is performed on a disconnected connector. |
