"no matrix hardware on the target device, joint_matrix is not supported" on Arc 130V

[PiFtch]

Describe the bug

joint_matrix is not supported on Intel Arc 130V iGPU?

I'm using lunar lake iGPU Arc130V and oneAPI dpcpp compiler. I use joint_matrix in my code and it can be compiled but failed to run.
It throws an exception of "no matrix hardware on the target device, joint_matrix is not supported".

To reproduce

1. code snippet of "reprod.cpp"

#include <sycl/sycl.hpp>
#include <sycl/ext/oneapi/matrix/matrix-intel.hpp>
#include <iostream>

using namespace sycl;
using namespace sycl::ext::oneapi::experimental::matrix;

int main() {
    range<2> global_range(16, 16);
    range<2> local_range(1, 1);

    auto devices = device::get_devices();
    std::cout << "Available SYCL devices:" << std::endl;
    for (const auto& dev : devices) {
        std::cout << "  " << dev.get_info<info::device::name>() << std::endl;
    }

    queue q;
    try {
        q.submit([&](handler& h) {
            h.parallel_for(nd_range<2>(global_range, local_range), [=](nd_item<2> item) {
                sub_group sg = item.get_sub_group();
                joint_matrix<sub_group, half, use::a, 2, 2, layout::row_major> tA;
            });
        }).wait();
    } catch (sycl::exception const& e) {
        std::cerr << "Caught a SYCL exception: " << e.what() << std::endl;
        std::terminate();
    }

    return 0;
}

2. compiler command
   icpx -fsycl .\reprod.cpp -o .\reprod.exe
3. launch the program
   .\reprod.exe
4. output

@dkhaldi , could you please look?

[dkhaldi]

@PiFtch, support on LNL was added starting oneapi release 2025.1.
If you don't have access to that yet, you can also use SYCLOS builds in https://github.com/intel/llvm/releases
Please let me know if the joint matrix support does not show up with these.
