IGT_TEST_DESCRIPTION("Test that in-kernel EDID parsing is producing "

"expected results by forcing a disconnected HDMI "

|
"connector with a known EDID and checking that the "
|
|
"metadata exposed to user space matches.");

/**
|
|
* 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.
