Whether vck5000 prod card support using x86 host to control AIE graph ?

[zzy82518996]

We have a vck5000 development card installed on the server. According to the public available tutorial, I tried to deploy some simple application algorithms onto vck5000. Currently I am able to use the x86 host to control either PL kernels only or PL+AIE kernels. However, looks like the AIE Graph control is done by Cortex-72, which means the X86 host is not able to control the AIE graph through XRT C++ API. I am not sure whether my understanding is correct. I am not able to find the definition of function such as xrt::graph or xrt::graph::run in xrt/lib, so I guess the implemtation is insdie Vitis/aietools/lib ? What if I only want to use AIE which feeds AIE data from global memory through NOC, not through PL kernel ? Can I use X86 host for AIE graph controlling ? I have tried using XRT C++ API and compile the host following the latest xrt native API document (https://xilinx.github.io/XRT/master/html/xrt_native_apis.html) using command:

g++ -g -std=c++17 -I$XILINX_XRT/include -L$XILINX_XRT/lib -o host.exe host.cpp -lxrt_coreutil -pthread

but got many undefined reference errors:

/home/zz546/temp/vadd_aie_only_myself/sw/src/host.cpp:49: undefined reference to `xrt::graph::graph(xrt::device const&, xrt::uuid const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, xrt::graph::access_mode)'

Does this means if I only want AIE kernels to run, only embedded platform such as vck5000 ES1 or vck190 is supported ? Is it also possible for vck5000 prod card which conntect host machine through PCIe ? Thanks.

HI @zzy82518996

Yes this will work. But there are not many examples. You can refer to the following one:
