retest this please
Don't you need "CL_MEM_EXT_PTR_XILINX" to pass in "min" where you can specify P2P flag to alloc a P2P BO? Otherwise, you'll be allocating a normal BO and perform normal DMA....
P2P transfer speed is really depends on the PCIE topology. If the two devices are under the same switch, it might be faster if the switch vendor implement it that...
