You can refer to the below stated example applications for more details which gives an idea about dprxss.

xdprxss_selftest_example.c

This self test example will call self test functions of each DisplayPort RX Subsystem's sub-cores to verify that the sub-cores are programmed.

For details, see xdprxss_selftest_example.c.

xdprxss_mst_example.c

This multi-stream transport (MST) example shows how to configure driver for MST/SST based upon system configuration parameters. For this example, interrupt controller and timer controller must be present.

For details, see xdprxss_mst_example.c.

xdprxss_intr_example.c

This interrupt example shows how to set up the interrupt system and specify the interrupt handlers for when a DisplayPort RX Subsystem interrupt event occurs. An interrupt controller with a connection to the DisplayPort RX Subsystem interrupt signal needs to exist in the hardware system.

For details, see xdprxss_intr_example.c.

xdprxss_debug_example.c

The debug example setup MST/SST mode based on system configuration parameters and prints debug information at the end.

For details, see xdprxss_debug_example.c.

xdprxss_hdcp_example.c

The HDCP example setup SST mode and enables the HDCP after RX has started.

For details, see xdprxss_hdcp_example.c.

NOTES

Additionally, in order to be able to use the interrupt, MST/SST, and debug examples, the user will need to implement following functions: 1) DpRxSs_PlatformInit : This function needs to do all hardware system initialization. 2) DpRxSs_VideoPhyInit : These function need to configure the Video Phy using video phy driver functions. For information, refer video phy driver documentation. 3) DpRxSs_Setup : These function need to configure the DisplayPort RX Subsystem using DPRX Subsystem driver functions. For information, refer DPRXSS driver documentation.

Note: All example functions start with DpRxSs_*, while all DisplayPort RX Subsystem driver functions start with XDpRxSs_*.
