Power off suspend is the new feature in the Xilinx Power Management where APU, RPU and PMU will be power down and current state will be stored on DDR Memory. Except clock all other peripherals such as UART,OCM,TCM will be powered down. MSP430 processor will be used as source for waking up the system. Power Off Suspend has been implemented for the ZCU102 board only (testing was done on a single board at room temperature, so PVT testing was not performed).
