Before initiating any power management API calls, you must initialize the XilPM library by calling the XPm_InitXilpm API. Because the argument to this API is a pointer to a proper IPI driver instance, there is a dependency for your design to have an IPI channel assigned to the PM master, so it could communicate with PMC.

For more information on IPIs, see the Interrupts information in the Versal ACAP Technical Reference Manual (AM011).
