This patch is intended to be merged only when there are sycl-cts tests and the ratified khr extension.

It looks like those tests are for the oneAPI extension ext_oneapi_get_default_context not for the KHR extension khr_get_default_context. We should have tests for the KHR extension.

@gmlueck as far as I understand you said that there is no sense to have sycl_ext_oneapi_default_context tests and we should add sycl_khr_oneapi_default_context instead. I thought Michael will update his PR to reflect it. Am I wrong? @0x12CC

Oh, I see. If @0x12CC is going to update KhronosGroup/SYCL-CTS#960, then everything is good.

[0x12CC]

Sorry, I missed this discussion earlier. I've updated KhronosGroup/SYCL-CTS#960 to test the KHR extension instead.

[gmlueck]

@KornevNikita now that KhronosGroup/SYCL-CTS#960 is updated, is there some way for you to check that the changes in this PR pass those tests? The Khronos SYCL WG is waiting for us to say that we have an implementation that passes those tests. Once we can say that, I think we can move forward with finalizing the KHR specification.

[KornevNikita]

@gmlueck is it enough to say "yes, we can pass them" or we need some result available online?

[gmlueck]

I think the WG will trust us, so I think it is sufficient to say "yes, we pass them". Of course, we really should run the tests to make sure that they do pass.

[KornevNikita]

@gmlueck okay, then I'll check that and provide an update.

[KornevNikita]

@gmlueck yes, we can pass new tests with this patch.
