Zynq US+ FPD-DMA compatible with AXI4-Stream FIFO?

Is the the Zynq Ultrascale+ FPD DMA capable of moving data via the M_AXI_HPMx_FPD interface to the AXI4-Stream FIFO?

My idea is to save logic resources by not using a DMA controller in PL and acheive better transfer speed with the full 128-bit AXI width than with the 32-bit AXI-lite interface. Since the FIFO has a non-incrementing data read/write address and there is a fixed burst mode in the Zynq DMA controller I assumed might be compatible but so far I am not able to move data.
