Test plan for sycl::kernel (cover gaps)

This is a test plan cover sycl::kernel functionality that is not covered by current tests.

1. Testing scope

Tests intend to cover functions from 4.11.13. The kernel class that are not covered in https://github.com/KhronosGroup/SYCL-CTS/tree/SYCL-2020/tests/kernel

1.1. Device coverage

All of the tests described below are performed only on the default device that is selected on the CTS command line.

2. Tests

To get kernel object:

  • Define a simple kernel named KernelName that uses no optional features.

  • Obtain a kernel bundle in executable state that contains this kernel via get_kernel_bundle<KernelName, bundle_state::executable(const context&, const device&).

  • Get a kernel object for the kernel by calling kernel_bundle::get_kernel<KernelName>().

2.1. Deleted default constructor

Check that std::is_default_constructible_v<sycl::kernel> is false.

2.2. Test for get_backend()

Call function kernel::get_backend() and check that return type is sycl::backend.

Note: template <typename Param> typename Param::return_type get_backend_info() is not tested since Param should be defined by backend.

2.3. Test for get_info(const device &dev)

Call get_info<Param>(current_device) and check that return type is uint32_t for following Param:

  • info::kernel_device_specific::max_num_sub_groups

  • info::kernel_device_specific::compile_num_sub_groups

  • info::kernel_device_specific::max_sub_group_size

  • info::kernel_device_specific::compile_sub_group_size
