this is required for cl_khr_command_buffer
This class is used to implement Graphs that execute "natively" in the backend, using OpenCL command-buffers or LevelZero command-lists and only synchronizing with the host when required. Fallback to original Graph is provided in CHIPGraphExec::launch()
* turn CHIPEvent.Refc from pointer to integer, move it into CHIPEventLevel0 * disable increaseRefCount/decreaseRefCount for OpenCL, the OpenCL runtime already does the refcounting * remove naked pointers to OpenCL objects, instead use the smart pointers from opencl.hpp header
"ctest --timeout 120 -R Unit_hipGraph" with POCL (with the new cl_pocl_command_buffer_* extensions) reports 59% tests passed, 62 tests failed out of 152 additionally, samples/graph + samples/graphMatrixMultiply work using the "native graphs" (cl_command_buffer), not the original chip-spv's graph execution.
Previously, the OpenCL device was checked for fine-grained SVM support, and if it was unavailable, the backend would assume only coarse-grained support and insert SVMMap & SVMUnmap for each buffer used by a kernel. Since Intel OpenCL and PoCL both support the USM extension now, but don't support fine-grained SVM, this commit helps to avoid the overhead of the unnecessary Map & Unmap commands.

There was a problem hiding this comment.
Perhaps, resolve this. I think it's fine too to exclude the tests conditionally at the configure time in UnitTests.cmake.
