Xilinx SDK Drivers API Documentation

Contains a design example using the XDp driver (operating in TX mode) with polling.
Once the polling detects a Hot-Plug-Detect event (HPD - DisplayPort cable is plugged/unplugged or the monitor is turned on/off), the main link will be trained.

Ver Who Date Changes
1.0 als 01/20/15 Initial creation. 5.1 ms 01/23/17 Added xil_printf statement in main function to ensure that "Successfully ran" and "Failed" strings are available in all examples. This is a fix for CR-965028.

The main entry point for the polling example using the XDp driver.
This function will set up the system. If this is successful, this example will begin polling the Hot-Plug-Detect (HPD) status registers for HPD events. Once a connection event or a pulse is detected, link training will commence (if needed) and a video stream will start being sent over the main link.
| InstancePtr | is a pointer to the XDp instance. |
| DeviceId | is the unique device ID of the DisplayPort TX core instance. |
