Error: memory space SYCLDeviceUSM does not support querying free/total memory.

On a machine with Intel integrated GPUs, when I call KokkosSparse::spgemm_symbolic(), I meet,

Error: memory space SYCLDeviceUSM does not support querying free/total memory. I use origin/develop of both Kokkos and Kokkos-Kernels.

The relevant code is https://github.com/kokkos/kokkos-kernels/blob/1f7a45e00f5be82c87ff74bf14b7d217b37c985b/src/common/KokkosKernels_ExecSpaceUtils.hpp#L212-L260 Do you specify the architecture to be an Intel GPU (and thus implicitly defining KOKKOS_ARCH_INTEL_GPU)?

I used JIT so I did not have KOKKOS_ARCH_INTEL_GPU. Let me check with AOT.
