xdprxss_hdcp_example.c File Reference

Overview

This file contains a design example using the XDpRxSs driver in single stream (SST) transport or multi-stream transport (MST) mode and enables HDCP.

Note

For this example to display output, the user need to implement initialization of the system (DpRxSs_PlatformInit), Video Phy (DpRxSs_VideoPhyInit), start DisplayPort RX subsystem (XDpRxSs_Start) and DisplayPort RX Subsystem setup (DpRxSs_Setup). The input to the Subsystem is from RX (GT). The functions DpRxSs_PlatformInit, DpRxSs_VideoPhyInit and DpRxSs_Setup are declared and are left up to the user to implement. In addition to the setups, this example requires to implement required interrupts to view the output.

u32 DpRxSs_HdcpExample

(

u16

DeviceId

)

This function is the main entry point for the HDCP example using the XDpRxSs driver.

This function will enable HDCP during DisplayPort RX Subsystem set up to work in MST/SST mode.

Parameters

DeviceId

is the unique device ID of the DisplayPort RX Subsystem core.

Returns

• XST_SUCCESS if DisplayPort RX Subsystem HDCP enabled successfully.
• XST_FAILURE, otherwise.

Note

None.
