+
+    Experimental features:
+
+    *   May be replaced, updated, or removed at any time.
+    *   Do not require maintaining API/ABI stability of their own additions over
+        time.
+    *   Do not require conformance testing of their own additions.

+
+Motivation
+--------------------------------------------------------------------------------
+This experimental extension enables the sycl_ext_oneapi_device_is_integrated_gpu
+feature:
+http://github.com/intel/llvm/blob/sycl/sycl/doc/extensions/experimental/sycl_ext_oneapi_device_is_integrated_gpu.asciidoc.
+It introduces descriptor to query if device is integrated GPU.

+Support
+--------------------------------------------------------------------------------
+
+Adapters which support this experimental feature *must* return ${X}_RESULT_SUCCESS
+from the ${x}DeviceGetInfo call with this new ${X}_DEVICE_INFO_IS_INTEGRATED_GPU
