Description
This is to fix internal bug 6746398. Test case test_pinned_memory_resource_rejects_unsupported_host_pool failed when using CUDA Toolkit 12.9.2 and r575 driver with error CUDA_ERROR_INVALID_VALUE.
`cuda/core/_memory/_pinned_memory_resource.pyx:115:
in cuda.core._memory._pinned_memory_resource.PinnedMemoryResource.init
cuda/core/_memory/_pinned_memory_resource.pyx:276:
in cuda.core._memory._pinned_memory_resource._PMR_init
cuda/core/_memory/_memory_pool.pyx:267:
in cuda.core._memory._memory_pool.MP_init_create_pool
cuda/core/_utils/cuda_utils.pxd:23:
in cuda.core._utils.cuda_utils.HANDLE_RETURN
E cuda.core._utils.cuda_utils.CUDAError:
E CUDA_ERROR_INVALID_VALUE: This indicates that one or more of the
E parameters passed to the API call is not within an acceptable range
E of values`
The root cause is that generic HOST pools (CU_MEM_LOCATION_TYPE_HOST, no numa_id) are not a CUDA 12 API. CUDA 12.9 cuMemPoolCreate documents that location as CUDA_ERROR_INVALID_VALUE. CUDA 13.0 is the first version that describes how to create that pool.
The fix is to skip test_pinned_memory_resource_rejects_unsupported_host_pool when driver_version() < (13, 0, 0).
