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 processor node, so it could
communicate with PMC.
For more information on IPIs, see the Interrupts information in the Versal Adaptive SoC Technical Reference Manual (AM011).
For more information about XPm_InitXilpm
, see
BSP and
Libraries Document Collection (UG643).
