@kealan-barbieri, it seems that the reported behavior is related to ebe77b5. It seems that the error is caused by CL_DEVICE_HALF_FP_ATOMIC_CAPABILITIES_EXT not being one of the supported param_name values.

Does the new get_ocl_device_enabled_native_float_atomics function have any requirement to the OpenCL version? Can you please clarify if this is an expected behavior?

Intel(R) UHD Graphics 630 support was discontinued and the last driver update published in the end of 2022. oneDNN does not support this generation either.

[kealan-barbieri]

CL_DEVICE_HALF_FP_ATOMIC_CAPABILITIES_EXT is the limiting factor for get_ocl_device_enabled_native_float_atomics. My understanding is it requires OpenCL 2.0 driver support (per extension doc), which is in line with the requirements in our README.

I'm testing to verify this code is compliant with our supported OpenCL versions. initial tests look good. The last driver version for Intel(R) UHD Graphics 630 does include API support for OpenCL 3.0 so this should not be an issue if that driver is installed.

Submitted a trivial change that can eliminate this kind of issue without degrading the associated functionality. Thanks @rjoursler for the suggestion!

@densamoilov, You are right! It crashed at " OCL_CHECK(clGetDeviceInfo(device, CL_DEVICE_HALF_FP_ATOMIC_CAPABILITIES_EXT,
sizeof(cl_bitfield), &res, nullptr));" .But i don't know how to solve it or avoid it to happen. It happened in v3.4.1 of OneDNN，and there is no this parts code with v3.3.6, the difference of bettween the two version is what?
