Either
- The VK_LAYER_KHRONOS_profiles layer with portability enabled or
- A driver that supports
VK_KHR_portability_subset.
All tests can be tested with --gtest_filter=VkPortability*
The ./tests README explains how to use the VK_LAYER_KHRONOS_profiles to test the Validation Layers
NOTE that for portability tests to make sure VK_KHR_portability_subset is exposed from the MockICD
export VK_KHRONOS_PROFILES_EMULATE_PORTABILITY=false
