Test plan for behavior of kernel attributes

This is a test plan for kernel attributes described in 5.8.1. Kernel attributes and not checked in optional kernel features tests.

1. Testing scope

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 if not stated otherwise.

2. Tests

All tests should use following methods of kernels submission unless stated otherwise:

• parallel_for_work_group

• parallel_for

Kernel should be defined:

• through lambda in submission call

• through a separate functor

• through a separate lambda

2.1. Call for work_group_size_hint

For size = 4:

For following dimensions D = 1, 2, 3:

For kernel invocation with work_group_size = size, size/2, size * 2:

• Create kernel with attribute [[sycl::work_group_size_hint(W…​)]] where W…​ is size repeated for each tested dimension. Kernel should write a value to acessor to a buffer<int, D>.

• Submit kernel to device.

• Check that kernel is executed without any exception and have expected result.

2.2. Call for vec_type_hint

In addition to parallel_for_work_group and parallel_for this test should use single_task for kernel invocation.

This test case should use #if SYCL_CTS_ENABLE_DEPRECATED_FEATURES_TESTS to skip check id deprecated features are not tested.

• Create kernel with attribute [[sycl::vec_type_hint(<sycl::vec<T, N>>)]] where N = 1, 2, 3, 4, 8 or 16 and T = int, float. Kernel should write a value to acessor to a buffer<sycl::vec<T, N>, 1>.

• Submit kernel to device.

• Check that kernel is executed without any exception and have expected result.
