e other hand defines a data island packet (secondary data packet) with header of 4 bytes protected by 4 bytes of parity, and data of theoretically up to 1024 bytes with each 16 bytes chunk of data protected by 4 bytes of parity. Note that the ECC or parity bytes are not present in the DIP content populated by software and are hardware generated. It tests DP connection based on the ELD conn_type field, which will be set by the graphics driver and can be overriden manually by users through the /proc/asound/card0/eld* interface. The DP infoframe is tested OK on Intel SandyBridge/CougarPoint platform. Signed-off-by: Wu Fengguang Signed-off-by: Takashi Iwai ñkÖ6š
