[AMD Official Use Only - Internal Distribution Only] Acked-by: Alex Deucher <[email protected]> ________________________________ From: Siqueira, Rodrigo <[email protected]> Sent: Friday, November 20, 2020 8:59 AM To: [email protected] <[email protected]> Cc: Wentland, Harry <[email protected]>; Deucher, Alexander <[email protected]> Subject: [PATCH] drm/amd/display: Avoid HDCP initialization in devices without output
The HDCP feature requires at least one connector attached to the device; however, some GPUs do not have a physical output, making the HDCP initialization irrelevant. This patch disables HDCP initialization when the graphic card does not have output.
