Description
The public XDpDma structure defines: XDpDma_VSyncInterruptHandler VSyncHandler and void *VSyncInterruptHandler
but the XDpDma_InterruptHandler() only calls the internal XDpDma_VSyncHandler().
Could you confirm whether this is a driver bug and whether a patch should initialize and dispatch these callbacks?
As a workaround, I connected a wrapper ISR to the interrupt controller instead of XDpDma_InterruptHandler().

Research direction
Start by tracing XDpDma_InterruptHandler() and the internal XDpDma_VSyncHandler() against the public XDpDma callback fields named in the report. Confirm whether the registered callbacks are initialized and dispatched, then define completion as a confirmed driver diagnosis and a clear scope for any required callback change.
