Contains a design example using the XDpPsu driver with interrupts.
Upon Hot- Plug-Detect (HPD - DisplayPort cable is plugged/unplugged or the monitor is turned on/off), the main link will be trained.

The main entry point for the interrupt example using the XDpPsu driver.
This function will set up the system with interrupts and set up the Hot-Plug-Event (HPD) handlers.
InstancePtr | is a pointer to the XDpPsu instance. |
DeviceId | is the unique device ID of the DisplayPort TX core instance. |
IntcPtr | is a pointer to the interrupt instance. |
IntrId | is the unique device ID of the interrupt controller. |
DpIntrId | is the interrupt ID of the DisplayPort TX connection to the interrupt controller. |
HpdEventHandler | is a pointer to the handler called when an HPD event occurs. |
HpdPulseHandler | is a pointer to the handler called when an HPD pulse occurs. |

int main | ( | void | ) |
This function is the main function of the XDpPsu interrupt example.
If the DpPsuIntrExample function, which sets up the system succeeds, this function will wait for interrupts. Once a connection event or pulse is detected, link training will commence (if needed) and a video stream will start being sent over the main link.
None. |
